A gearbox is a mechanical device that transfers energy from one device to another. It is used to change the speed (RPM) or the output torque of a motor. It is also known as gear reducer, speed reducer, reduction gearbox or gearhead.

It has applications across a wide range of industries. For example, a gearbox is used to offer loads in the power transmission industry. On the other hand, motion control or servo industry might use it for handling dynamic motion applications.

All types of gearboxes operate in a similar way. A pair of the identical intermeshing modules (tooth shape) transfers the power from the A-axis (delivery) to the Z-axis. A gearbox can provide reliable power transmission as you can calculate the reduction gearbox speed ratio by adjusting the relative number of teeth.

Based on the shape, structure and application, the gearbox types can be classified into many categories: right angle gearbox,  worm gear box, motor gearbox, mini gearbox, planetary gear box, parallel shaft gearbox, servo gearbox, high torque gearbox, harmonic gearbox, lathe gearbox, slew drive gearbox, industrial gearbox, inline gearbox reducer, double reduction gearbox, hollow shaft gearbox, bevel gearbox, helical gearbox. As the gears are the core of all types of gearboxes. You can summarize the gear box from the classification of gear manufacturing. The all gear type: worm gear, spur gear, bevel gear, helical gear, planetary gear, spiral bevel gear. You can find that there are several main transmission gearbox actually:worm gearbox, planetary gearbox, 90 degree gearbox, slew drive, screw jacks (screw gear with shaft). In short, from any industrial equipment or transmission equipment, you can find the use of gear reduction box.

Based on gearbox transmission ratio, speed, lubrication requirements, reliability, cost, and transmission efficiency, different gearbox design structures have unique advantages and disadvantages.

What gearbox type we can offer? One simple list here: Worm gearbox, worm and worm wheel, spur gearbox, plastic gearbox, helical gearbox, spiral bevel gearbox, in-line gearbox, right angle gearbox, small gearbox, planetary gearbox and custom gearbox.

How to Select the Right Gearbox

  • Confirm various structural and dynamic parameters such as the transmission structure size, quality, power, speed, efficiency, gear ratio, and load characteristics.
  • Check the performance specifications such as reliability, service life, noise, vibration, temperature, and transmission accuracy.
  • Pay close attention to the choice of material, gearbox technology, and generic interchangeability.
  • Make sure to choose gear products with low-cost but high efficiency, precision, and reliability.
