Helical Gear Speed Reducers
Provide high-efficiency speed reduction through 1, 2, 3, or 4 sets of gears. Power is certainly transmitted from a high-speed pinion to a slower-speed equipment. Helical gears generally operate with their shafts parallel to one another. The two most common types will be the concentric (insight and result shafts are in line) and parallel shaft (input and result shafts are offset). Single-stage helical gear reducers are usually used for equipment ratios up to about 8:1. Where reduce speeds and higher ratios are necessary, dual, triple, and quadruple gear reduction stages may be used.

Worm Gear Speed Reducers
A single reduction rate reducer can achieve up to 100:1 decrease ratio in a little package. Known as right position drives, these consist of a cylindrical worm with screw threads and a worm. With a single start worm, the worm gear advances only one tooth for every 360-degree turn of the worm. So, whatever the worm’s size, the apparatus ratio is the ‘size of the worm equipment to 1′. Higher decrease ratios can be created through the use of double and triple reduction ratios.

Basic Types of right angle worm gearbox Gearboxes

The objective of a gearbox is to improve or reduce speed. Because of this, torque output will be the inverse of the function. If the enclosed drive can be a acceleration reducer, the torque result will increase; if the drive increases speed, the torque result will decrease. Gear drive selection elements include: shaft orientation, acceleration ratio, design type, nature of load, gear ranking, environment, mounting position, working temperature range, and lubrication.
