Helical Gear Speed Reducers
Provide high-efficiency speed reduction through 1, 2, 3, or 4 models of gears. Power can be transmitted from a large-acceleration pinion to a slower-speed equipment. Helical gears generally operate with their shafts parallel to each other. The two most common types will be the concentric (insight and output shafts are in series) and parallel shaft (insight and output shafts are offset). Single-stage helical gear reducers are typically used for equipment ratios up to about 8:1. Where reduced speeds and higher ratios are required, double, triple, and quadruple gear reduction stages may be used.
Worm Gear Speed Reducers
A single reduction swiftness reducer can achieve up to a 100:1 reduction 
ratio in a small package. Referred to as right angle drives, these contain a cylindrical worm with screw threads and a worm. With an individual start worm, the worm equipment advances only 1 tooth for every 360-degree convert 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 by using double and triple decrease ratios.
Basic Types of Gearboxes
The objective of a gearbox is to increase or reduce speed. Because of this, torque output will be the inverse of the function. If the enclosed travel is a quickness reducer, the torque result increase; if the drive raises speed, the torque output will decrease. Gear drive selection factors include: shaft orientation, speed ratio, design type, character of load, gear rating, environment, mounting position, working temperature spectrum, and lubrication.
