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

Worm Gear Speed Reducers
A single reduction quickness 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 an individual start worm, the worm gear advances only one tooth for every 360-degree turn of the worm. So, regardless of the worm’s size, the gear ratio may be the ‘size of the worm gear to 1′. Higher decrease ratios could be created through the use of double and triple decrease ratios.

Basic Types of Gearboxes

The right angle worm gearbox 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 velocity reducer, the torque output increase; if the drive increases speed, the torque result will reduce. Gear drive selection factors include: shaft orientation, rate ratio, design type, character of load, gear rating, environment, mounting position, working temperature range, and lubrication.
