‌‌Structural advantages and selection of helical planetary gearboxes

1.Introduction to helical planetary gearboxes ‌Helical planetary gearboxes‌ are a mechanical transmission device composed of a planetary gear mechanism and helical gears. The core lies in the layout of the planetary gears. The central sun gear is surrounded by multiple planetary gears, and the outer side of the planetary gears is wrapped with an annular gear ring, and all gear axes remain parallel. The characteristic of helical gears is that the tooth shape is inclined at an angle to the axis, and the common angle range is between 15 degrees and 30 degrees. This design makes the gear meshing process more coherent and effectively reduces the operating noise. ‌ .

2.Working principle of helical planetary gearboxes The working principle of helical planetary gearboxes is based on the layout of planetary gears and the meshing characteristics of helical gears. When the motor drives the sun gear to rotate, the planetary gears generate a reaction force during the self-rotation process, pushing the planet carrier to start rotating. The unique meshing method of the helical gears causes an axial component of force to exist at each contact point, and this force is transmitted to the output shaft through the planet carrier. Because multiple planetary gears share the load at the same time, this structure has a load-bearing capacity of about 40% higher than that of parallel shaft gearboxes at the same volume, which is particularly suitable for heavy-duty equipment.

3.Structural advantages of helical planetary gearboxes 1.Reduce shock and vibration: The helical tooth design of the helical gear makes the contact line longer and the meshing smoother during the transmission process, effectively reducing shock and vibration. The planetary gear has a compact structure and even power distribution, which further improves the stability of the system. ‌2.High transmission efficiency: The transmission efficiency of the helical planetary gearbox can usually reach more than 90%, or even higher. Efficient energy conversion means that more input power is converted into useful output torque, reducing energy loss. ‌3.High-precision transmission: Through high-precision processing and assembly, the helical planetary gearbox can achieve extremely high transmission accuracy and is suitable for occasions with high precision requirements. ‌4.High load-bearing capacity: The multi-tooth meshing design of the helical gear and the distributed design of the planetary gear enable the gearbox to withstand large loads and torques, especially for heavy-load conditions. ‌5.Low noise: The helical angle design of the helical gear disperses the meshing frequency to different phases, and the symmetrical layout of the planetary gear train offsets some vibration harmonics, thereby reducing noise. Comparative tests in a certain automobile transmission laboratory show that at the same speed, the helical planetary structure has an 8-12 dB lower sound pressure level than the spur planetary structure. ‌6.Compact design‌: The planetary gear has a compact structure, small size and light weight, which is suitable for use in environments with limited space. This is very beneficial for some compact mechanical equipment. ‌7.Long life‌: With high-quality materials and advanced heat treatment technology, the helical planetary gearbox has excellent wear resistance and fatigue resistance, which prolongs the service life.

4.Selection of helical planetary gearbox ‌1.Reduction ratio selection‌: The reduction ratio is one of the key parameters for the selection of helical planetary gearboxes. The selection of the reduction ratio should be determined according to the actual load characteristics and the required output torque. For heavy loads, a higher reduction ratio should be selected; for light or medium loads, a lower reduction ratio can be selected. In addition, the selection of the reduction ratio also needs to consider the rated power and speed of the motor. ‌2.Accuracy selection‌: The accuracy (return clearance) of the planetary reducer directly affects its transmission performance and stability. The smaller the return clearance, the higher the accuracy, but the higher the cost. Users should choose a reducer that meets the accuracy requirements according to actual needs. ‌3.Materials and design‌: The use of high-quality low-carbon alloy steel and the grinding process can reduce noise and vibration. The hardness of the working tooth surface of the small gear should be slightly higher than that of the large gear. In addition, the use of a smaller pressure angle and helical gear design can also help reduce vibration and noise. ‌4.Economic considerations‌: The cost of a planetary reducer is closely related to its speed ratio. On the premise of meeting the use requirements, an economically reasonable speed ratio selection should be pursued to reduce the overall cost of the equipment. ‌5.Installation space‌: Select a planetary reducer with a compact structure that meets specific space requirements to adapt to the limitations of the actual installation space. ‌6.Service life‌: Consider axial/radial force and average life. Reducers with large axial/radial forces are highly reliable during installation and use, and their actual life is usually far longer than the life of the servo motor they are equippe.

A Guide To Choosing A Harmonic Drive Gearbox

In both industrial and commercial machinery, a harmonic drive gearbox is an essential component that must be present. It can transfer rotational power into linear motion, hence enabling machines to move at great speeds with very little effort being exerted. There are many different avenues available for you to pursue to acquire the ideal harmonic drive gearbox for your company; however, why should you go with anyone other than UKHarmonicDrives?

Torque output

The harmonic drive gearbox is physically attached to the machinery that it controls, and for a gearbox to be constructed, it must have the capability of operating the machinery in question. This includes the torque that is created during jams and load shocks, as well as the torque that is necessary to start and accelerate the machinery (which may be significantly more than when it is running at operating speed).

The amount of speed produced

If the application requires a specific speed output, the gearbox must maintain that speed while providing sufficient torque to the driven load. At the same time, it may seem counterintuitive at first, but as rotational speed increases, available torque decreases (due to inevitable friction losses). This makes it imperative that gears are chosen to provide enough torque for maximum speed targets.

The importance of service factors

The service factor of the harmonic drive gearbox system refers to the proportion of the gearbox's rated torque that it can maintain for relatively short amounts of time. If the gearbox is going to be subjected to frequent quick accelerations or periodic load spikes on the output, the service factor needs to be significantly increased. Because gear reducers do not have a cooling fan, the service factor is also determined by the total number of hours that the gear reducer is utilized each day.

Mounting and connecting attributes and qualities

Because the gearbox mounting area has space and profile limits, the size, shape, and arrangement of the gearbox are significant factors to consider when selecting which alternative is suitable. There are several distinct kinds of gears, each of which has its own unique size efficiency. Planetary gear trains are typically the most space-efficient, but spur gears require a far more extensive footprint.

Backlash

Backlash is the amount of error or play in the meshing of the gears in the gearbox. The resulting mechanical shock when starting or stopping a gearbox is called backlash. A small amount of play is desirable for smooth motion, but an excessive amount can cause damage to parts and wear of bearings.

Radial load

Radial load is the force that is placed on the output shaft of the gearbox when it is connected to the driven load in a manner that creates a right angle, such as when a belt pulley or sprocket is used to link the gearbox to the driven load. The radial load rating of a component is typically stated in kilograms per square centimetre and represents the maximum safe operating pressure based on how much metal must be compressed before it breaks. This is done so because the radial load rating is directly proportional to the amount of force required to break the component. The higher the number, the greater the amount of metal that can be utilized for a certain application without causing it to become overloaded.

Transmissions using helical gears

The Helical gearbox is an excellent option to go with if you are looking for a product that is both effective and dependable and that is also capable of managing applications that require a high level of physical strain. This gearbox is well-known for its specialized performance, which enables personnel who operate industrial equipment to achieve higher levels of productivity. In addition to being utilized in transmission systems and motion control units, this gearbox design can also be found in use.

Transmission systems that use planetary gears

The input shaft and output shaft of planetary gearboxes are perfectly aligned with one another. Because of this, a high degree of torque density may be achieved, which facilitates the transfer of the greatest amount of torque in the most compact form. These transmissions create nearly three times the amount of torque that is produced by a conventional gearbox since the torque is distributed across three gears of similar diameters.

Worm reduction gearboxes are the subject of this article

Worm Reduction Gearboxes consist of a huge worm wheel that revolves in a screw-like movement. These gearboxes provide you with the ability to improve the speed reduction between non-intersecting crossing axis shafts. This comes in especially handy for tasks involving things like CNC equipment and 3D printers. Despite this, they are among the least efficient gearboxes that can be purchased, which means that when using worm reduction gearing, careful consideration of the motor selection is essential.

Motors, Lubricant, and Seals all come into consideration

After the unit size and configuration have both been finalized, there are a few more stages that need to be addressed. The majority of manufacturers provide consumers with the choice to have their gearboxes shipped with the lubricant already installed (for most, the default is to ship units empty and let customers fill them on site.) Some manufacturers will propose a second set of seals for applications in which there is a vertical shaft down. These are situations in which the shaft is pointing downward.

The Temperature and Conditions of the Ambient Environment

A particular atmosphere is required for the gearbox to function properly. When determining the size of a gearbox, crucial criteria include the temperature of the surrounding air, the type of fluid being used, and the material used for the seals. The service factor that is applied will need to be increased to account for the higher temperatures. In a similar vein, your machine may need a variable viscosity of lubricant depending on the temperature to continue functioning properly.

If you are interested in purchasing a harmonic drive gearbox, the torque capacity of the product is the very first thing you will want to take into consideration before making a purchase decision. Depending on the requirements of your application, you will also need to choose the configuration of the input and output shafts. When searching for a harmonic drive gearbox, one more factor that should not be ignored is the question of whether or not it can survive extreme environments. Before you make a final decision about which product is ideal for your application, it is important to take into consideration not only the price but also the dimensions and weight of each option.

Top Considerations When Selecting A Harmonic Drive Gearbox

A harmonic drive gearbox is a type of gearbox that uses a harmonic oscillator to transmit power. The harmonic oscillator is a device that converts rotational motion into linear motion or vice versa. This type of gearbox is used in applications where high torque and low speed are required. When looking for a harmonic drive gearbox, here are some things you should consider:

Purpose

Understanding how the gearbox and engine will be utilised is the first step to determining the best assembly for the application. It's critical to fully comprehend how the motor gearbox assembly will be used and its intended function.

Compatibility

It's critical to verify that the motor and gearbox are compatible technologies when selecting the best harmonic drive gearbox and motor combination.

Desired output

Changing the gearbox's configuration impacts the torque and speed of the motor's output. Ensuring that the system can meet the required standards should not be underestimated.

Efficiency

With so many components, it's easy to imagine that maintaining a high-level operational efficiency is difficult. As previously stated, the effective functioning of the whole motor and gearbox configuration relies on numerous elements. However, ensuring that the harmonic drive gearbox  is correctly linked to achieving the desired output may improve motor performance.

Power source

If you have a motor and gearbox assembly with an insufficient power source, it can put your engine under strain. This can lead to early deterioration and necessitate maintenance or replacement.

Using multiple gearbox motors

If a single motor isn't enough to meet the need, it's worth considering whether multiple motors would work better.

Service factor

The service factor is the first step for most harmonic drive system makers. This gadget helps to compensate for different things that might affect how it works. Things like different input, how many hours per day it is used, and any shock or vibration present. If there is a shock that is not regular, like if something is grinding, then you will need a higher service factor. And if it is only used sometimes, like a backup power source, you will want a lower service factor.

Class of service

Once you've established this variable, it will define a category of service. A service class 2 is usually given to a machine driven by a plain AC motor that drives an evenly loaded, constant speed conveyor for 20 hours each day.

Overhung load

The harmonic drive system manufacturer's catalogue or website lists the maximum overhung load for given unit size. Suppose the load in an application is greater than the permitted maximum. In that case, the gearbox may need to be up-rated to accommodate the overhanging loading.

Mounting

Mounting options vary depending on the gearbox model, although there are several typical installations. Gearbox makers provide a wide range of alternatives for each unit size. Still, there are many more alternatives to choose from. Mounting feet above or below the body of the gearbox, hollow outputs, and input/output configuration are all possible choices. All gearbox manufacturers offer mounting possibilities and dimensions in catalogues and websites.

Torque output

The harmonic drive gearbox must deliver enough torque to operate the equipment it is connected to. This comprises the requisite torque to start and accelerate machinery, which might be considerably greater than ordinary operational torque and the induced torque created by jams and load shocks.

Speed output

Suppose the application demands a particular speed output. The gearbox must keep that speed while also delivering enough torque to the driven load.

Service factor

The service factor of the gearbox is the percentage of its maximum torque that it can endure for short periods. A large service factor is required if the output will be subjected to regular quick accelerations or occasional load spikes. Because gear reducers do not have a cooling fan, the service factor is also determined by how many hours a day it is used. The larger the production shift, the greater the space required to dissipate produced heat.

Mounting and connection characteristics

If the gearbox mount location has space and profile limitations, the gearbox size, form, and configuration must be considered when selecting a solution. The efficiency of different forms of gearing varies considerably, with planetary gear trains being the most compact while spur gears requiring a larger amount of volume.

Backlash

Backlash is the amount of error or play in the gearmotor's meshing, which results in a gearbox that feels mechanical shock when started or stopped.

Radial load

The force on the output shaft of a gearbox at right angles, such as with a belt pulley or sprocket, is known as a radial load. Different radial load tolerances are required for gearboxes, so double-check that your application's operational conditions will not overload the gearbox.

Harmonic drive gearboxes from companies like UK Harmonic Drives are a specialised type of gearbox that use elliptical gears to provide high torque and speed ratios with very little backlash. They are commonly used in applications where precise motion control is required, such as medical equipment, semiconductor manufacturing, and laboratory automation. Because harmonic drive gearboxes are expensive and require more careful installation than traditional gearboxes. It is important to select the correct model for your specific application before ordering.

HARMONIC GEARS

Introduction

Harmonic drive developed a unique gear tooth profile that optimizes the tooth engagement. This tooth profile enables up to 30% of the total number of teeth to be engaged simultaneously. Additionally, the large tooth root radius increases the tooth strength compared with an involute tooth. Harmonic Drives have been employed in a variety of applications such as military and aerospace use. Harmonic gearbox is also known as Strain Wave gearbox. Harmonic gearing is a type of mechanical gear system that uses a flexible spline with external teeth, which is deformed by a rotating elliptical plug to engage with the internal gear teeth of an outer spline.

Harmonic gearbox came with its attractive features like compactness and light weight, High gear ratio. It comes with reconfigurable ratios within a standard housing.  Harmonic reducer has a high torque capability with coaxial input and output shafts. The one of the main feature of harmonic drive reducer is, it comes with no backlash. It can provide reduction but can be also used to increase rotational speed.    

Harmonic drive components

The mechanism of Strain wave drive consists of a toothed mechanism comes with 3 components i.e. Circular spine, Flex spine, Wave Generator.

The circular spline is a solid steel ring with internal teeth. The flex spline is a flexible steel cylinder with external teeth. The drive is executed by the wave generator, It’s a thin-race ball bearing that is fitted onto an elliptical plug. The elliptical shape of the wave generator helps the teeth of the flexspline to engage circular spline at two regions at opposite ends of the major axis of the ellipse.

Applications of Harmonic Gearbox

Harmonic gearbox can be used in any gear reduction application where small size, low weight, zero backlash, very high precision and high reliability are required. Examples include aerospace applications, robotics, electric vehicles, medical x-ray and stereotactic machines, milling and lathe machines, flexo-printing machines, semiconductor equipment, optical measuring machines, woodworking machines and camera head pans and tilt axes. The Harmonic gear box is very useful when the axis moments are required for example in Robot arm.
