Helical Gear Speed Reducers
Provide high-efficiency speed reduction through 1, 2, 3, or 4 units of gears. Power can be transmitted from a high-acceleration pinion to a right angle worm gearbox slower-speed gear. Helical gears usually operate with their shafts parallel to one another. The two most common types are the concentric (insight and output shafts are in series) and parallel shaft (insight and result shafts are offset). Single-stage helical equipment reducers are usually used for equipment ratios up to about 8:1. Where decrease speeds and higher ratios are necessary, double, triple, and quadruple equipment reduction stages may be used.

Worm Gear Speed Reducers
A single reduction speed reducer can achieve up to a 100:1 decrease ratio in a little package. Referred to 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 switch of the worm. So, regardless of the worm’s size, the apparatus ratio is the ‘size of the worm gear to 1′. Higher reduction ratios can be created by using double and triple reduction ratios.

Basic Types of Gearboxes

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