Top 10 tips for working with gearmotors_2

Top 10 tips for working with gearmotors_2

1. Understand what causes gearmotor failure. Excessive overhung loading (radial load on shaft) can destroy bearing support systems. Shaft fatigue failure is also common on overloaded shafts. Gearboxes that experience shock loads from large inertia loads or excessive acceleration/deceleration can cause gear tooth fracture. High thrust forces on shafts can exceed bearing capabilities, compromise…

Top 10 tips for working with gearmotors(1)

Top 10 tips for working with gearmotors(1)

1. When specifying, start by determining the required torque at the gearbox output shaft. A gearmotor‘s purpose is to act as a power transmission component. As such, the two most important factors at the gearbox output shaft are its speed (in rpm) and how much work it can do, as determined by the amount of torque it produces. Typically, gearboxes serve to take motor power, reduce its speed, and…

How Does a Crane Work?

How Does a Crane Work?

What Is a Crane? A crane is a mechanism that uses a collection of simple machines to both raise and lower objects, and also move them horizontally. They are always equipped with at least a winder; cables, ropes or chains; and sheaves. Both sheaves and the winder are a form of pulley. Lifting Cranes can use a combination of simple machines to gain mechanical advantage and lift objects. The first…

Worm Gear – Definition, Working & Applications

Worm Gear – Definition, Working & Applications

 Worm gears are special gears used in rudders, automobile steering mechanisms, hoists and rolling mills. A worm gear drive consists of two elements: Driving element → Screw Driven element → Helical gear Driving element (screw) is called worm and driven element (helical gear) is called worm gear or worm wheel.   Worm gear drives are typically used for transmission of power between two non-parallel…

Dual lead worm gears

Dual lead worm gears

Dual lead worm gears, as their name suggests, are constructed with two leads. One flank of the worm thread and its mating sides of the wheel teeth are manufactured with one lead, and the other flank and its mating wheel teeth to a slightly different lead.   As far as the worm is concerned this had the effect of producing a worm thread which increases in thickness from one end of the worm to the…

Gears

Have you ever tried pedaling a bicycle up a really steep hill? It’s pretty much impossible unless you use the right gear to increase your climbing force. Once you’re back on the straight, it’s a different story. Flick to a different gear and you can go incredibly fast: you can magically make your wheels turn round much faster than you’re pedaling. Gears are helpful in machines of all kinds, not…

General Explanation about Speed Reducer

General Explanation about Speed Reducer

Speed reducers are mechanical devices generally used for two purposes. The primary use is to multiply the amount of torque generated by an input power source to increase the amount of usable work. They also reduce the input power source speed to achieve desired output speeds. The selection and integration of speed reducers entails much more than simply picking one out of a catalog. In most cases…

Speed Reducer Frequently Asked Questions

Speed Reducer Frequently Asked Questions

    Q. Why use a worm gear reducer? A. A worm gear reducer is a right angle gear solution that allows the maximum speed reduction in the smallest package. Q. Why use a bevel gearbox? A. A bevel gearbox is yet another right angle gear solution but its efficiency is much higher than the worm gear. If you need a right angle solution with a low ratio the bevel gear is the right choice. Q. Why use…

What’s the Difference Between Spur, Helical, Bevel, and Worm Gears?

What’s the Difference Between Spur, Helical, Bevel, and Worm Gears?

Gears are a crucial part of many motors and machines. Gears help increase torque output by providing gear reduction and they adjust the direction of rotation like the shaft to the rear wheels of automotive vehicles. Here are some basic types of gears and how they are different from each other. Spur Gears The most common gears are spur gears and are used in series for large gear reductions. The…
