Helical Gear Speed Reducers
Provide high-efficiency speed reduction through 1, 2, 3, or 4 units of gears. Power is usually transmitted from a high-velocity pinion to a slower-speed gear. Helical gears generally operate with their shafts parallel to each other. Both most common types will be the concentric (input and output shafts are in range) and parallel shaft (input and output shafts are offset). Single-stage helical gear reducers are usually used for gear ratios up to about 8:1. Where reduce speeds and higher ratios are required, double, triple, and quadruple equipment reduction stages may be used.

Worm Gear Speed Reducers
A single reduction swiftness reducer can achieve up to 100:1 decrease ratio in a little package. Known as right angle drives, these contain a cylindrical worm with screw threads and a worm. With a single start worm, the worm equipment advances only one tooth for each 360-degree change of the worm. So, regardless of the worm’s size, the apparatus ratio may be the ‘size of the worm equipment to 1′. Higher reduction ratios could be created through the use of double and triple reduction ratios.

Basic Types of Gearboxes

The purpose of a gearbox is to improve or reduce speed. As a result, torque output would be the inverse of the function. If the enclosed drive can be a rate reducer, the torque output increase; if the drive raises speed, the torque output will decrease. Gear drive selection elements include: shaft orientation, velocity ratio, design type, nature of load, gear rating, environment, mounting position, operating temperature range, and lubrication.
