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

Worm Gear Speed Reducers
A single reduction rate reducer can achieve up to a 100:1 reduction ratio in a small package. Known as right position drives, these consist of a cylindrical worm with screw threads and a worm. With an individual 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 gear ratio is the ‘size of the worm equipment to 1′. Higher decrease ratios can be created by using double and triple reduction ratios.

Basic Types of Gearboxes

The objective of a gearbox is to increase or reduce speed. Consequently, torque output would be the inverse of the function. If the enclosed drive is a quickness reducer, the torque result will increase; if the get improves speed, the torque output will decrease. Gear drive selection elements include: shaft orientation, speed ratio, design type, character of load, gear ranking, environment, mounting position, operating temperature selection, and lubrication.
