Types of Gear Reducers

You can never talk of a motor without talking about a gear. They increase torque output through provision of gear reduction, and adjust the direction of rotation of shafts. Engine’s acts as a hub for power distribution to propel machines and run them at a high speed, to generate enough energy to perform a certain designated work. Although machines are highly dependent on engines, they do not reciprocate the same speed as it would be difficult to control them and their functions. Gear reducers are fixed to control the speed and torque of an engine by utilizing different gear ratios and are used on all types of electrical, mechanical and hydraulic motors.


There are many types of gear boxes characterized with their performance due to different sizes, ratio and efficiencies. Gear reducers are basically classified as spur, helical, worm and bevel gear reducers. Spur gears are used in large gear reduction and their teeths are straight, mounted in parallel on different shafts. Gear ratio ranges from 1:1 to 6:1 and efficiency, 94% to 98%. Helical gears are cut at an angle to allow gradual contact between the teeths. Gear ratios range from 3:2 to 10:1 and efficiency, 94% to 98%. Bevel gears are categorized into three straight with ratio of 3:2 to 5:1, spiral has ratio of 3:2 to 4:1 and hypoid gears with ratio of 10:1 to 200:1. Worm gears are also used in large gear reduction and their ratio ranges from 5:1 to 300:1. Example of different gear reducers are single reduction spur, single reduction bevel gear, double reduction bevel gear, co axial spur gear, multi speed gear reducers, triple reduction worm gear among others.
