Helical Gear Speed Reducers
Provide high-efficiency speed decrease through 1, 2, 3, or 4 pieces of gears. Power can be transmitted from a high-speed pinion to a slower-speed equipment. Helical gears usually operate with their shafts parallel to each other. Both most common types will be the concentric (input and result shafts are in range) and parallel shaft (insight and output shafts are offset). Single-stage helical equipment reducers are usually used for equipment ratios up to about 8:1. Where reduced speeds and higher ratios are required, double, triple, and quadruple gear reduction stages can be used.
Worm Gear Speed Reducers
A single reduction speed reducer can achieve up to a 100:1 decrease ratio in a little package. Known as right position drives, these contain a cylindrical worm with screw threads and a worm. With a single begin worm, the worm gear advances only 1 tooth for each 360-degree change of the worm. So, regardless of the worm’s size, the gear ratio may be the ‘size of the worm gear to 1′. Higher reduction ratios could be created by using double and triple decrease ratios.
Basic Types of Gearboxes
The purpose 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 is usually a acceleration reducer, the torque output will increase; if the drive boosts speed, the torque result will decrease. Gear drive selection factors include: shaft orientation, velocity ratio, design type, nature of load, gear ranking, environment, mounting position, working temperature range, and lubrication.
