A gearbox is a mechanical device utilized to increase the output torque or change the speed (RPM) of a motor. The motor's shaft is attached to one end of the gearbox and through the internal configuration of gears of a gearbox, provides a given output torque and speed determined by the gear ratio.
Why do motors need gearbox?
Gearboxes reduce speed and increase torque Whilst there are occasionally gearboxes that will increase speed and reduce torque, in the vast majority of cases, a gearbox will be used to reduce the shaft speed of a motor and increase the torque.
What is difference between gearbox and motor?
Simply put, a gear motor is an electric motor coupled with a gearbox. In most cases, the addition of a gearbox is intended to limit the speed of the motor's shaft and increase the motor's output torque.
What is Gearbox and its function?
In the most basic sense, a gearbox functions like any system of gears; it alters torque and speed between a driving device like a motor and a load. ... The gearbox is a mechanical method of transferring energy from one device to another and is used to increase torque while reducing speed.Aug 4, 2017
How do I choose a motor and gearbox?
- Service Factor. Before sizing an application, the customer should determine the service factor. ...
- Ambient Temperature and Environment. ...
- Shock Load or Type of Load. ...

- Output Shaft or Hollow Bore Size. ...
- Housing Styles.
Is a gearbox a motor?
Simply put, a gear motor is an electric motor coupled with a gearbox. ... Gears transform shaft speed and torque at specific ratios, with minimum efficiency losses, which makes it possible to create the ideal output speed and torque with the addition of an appropriately sized and configured gearbox.
Is the need of the gearbox?
The purpose of a gearbox is to increase or reduce speed. As a result, torque output will be the inverse of the speed function. If the enclosed drive is a speed reducer (speed output is less than speed input), the torque output will increase; if the drive increases speed, the torque output will decrease.
What is the difference between motor and gear motor?
1 Answer. A DC motor is not the same as a "gear motor" - a "gear motor" may be an AC or DC motor coupled with a gearbox or transmission. A gear motor adds mechanical gears to alter the speed/torque of the motor for an application. Usually such an addition is to reduce speed and increase torque.
Why do we use gearbox in motor?
A gearbox—otherwise known as a gear reducer or speed reducer—is a set of gears that can be added to a motor to drastically decrease speed and/or increase torque. ... Each gearbox type works in unison with a motor to achieve the desired speed-torque output.May 25, 2018
