A gear reducer is a power transmission mechanism that uses the speed converter of gears to decelerate the number of revolutions of a motor to the desired number of revolutions and to obtain a larger torque. So how does it work?
The gear reducer is used to reduce the speed by using all levels of gearing. The speed reducer is composed of various levels of gears. For example, if a large gear is driven by a small gear, it can achieve a certain speed reduction, and then use a multi-stage structure, it can greatly reduce the speed.
Gearmotors are generally used for low-speed, high-torque transmission equipment, to reduce the speed of electric motors. Internal combustion engine or other high-speed power through the gear on the input shaft of the reducer with fewer teeth to mesh with the output shaft of the large gear to achieve the purpose of deceleration, ordinary reducer will also have several pairs of the same principle gear to achieve the desired deceleration effect, the ratio of the number of teeth of the large and small gears, is the transmission ratio.
Decelerate the speed and increase the output torque at the same time. The ratio of torque output is according to the motor output multiplied by the reduction ratio, but be careful not to exceed the rated torque of the reducer.
The reduction in speed also reduces the inertia of the load, and the reduction in inertia is the square of the reduction ratio. You can look at the general motor has an inertia value. Types of reducers General reducers include helical gear reducers (including parallel shaft helical gear reducers, worm gear reducers, bevel gear reducers, etc.), planetary gear reducers, cycloid gear reducers, worm gear reducers, planetary friction mechanical stepless speed changers, etc.
