right angle worm gearbox

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

Worm Gear Speed Reducers
A single reduction acceleration reducer can achieve up to 100:1 decrease ratio in a little package. Known as right angle drives, these contain a cylindrical worm with screw threads and a worm. With an individual begin worm, the worm gear advances only 1 tooth for each 360-degree convert of the worm. So, regardless of the worm’s size, the apparatus ratio may be the ‘size of the worm gear to 1′. Higher decrease ratios can be created by using double and triple reduction ratios.

Basic Types of Gearboxes

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