The gear reducer is a power transmission mechanism that uses the speed converter of the gear to reduce the number of revolutions of the motor to the desired number of revolutions and obtain a large torque.So how does it work?
The gear reducer uses various levels of gear transmission to achieve the purpose of speed reduction. The reducer is composed of various levels of gear pairs. For example, a small gear can be used to drive a large gear to achieve a certain deceleration purpose, and then a multi-stage structure is adopted. , You can greatly reduce the speed.
Gear reducers are generally used for low-speed and high-torque transmission equipment. The power of electric motors, internal combustion engines or other high-speed running powers through the gears with fewer teeth on the input shaft of the reducer meshes with the large gears on the output shaft to achieve the purpose of speed reduction. The speed reducer of the gearbox will also have several pairs of gears with the same principle to achieve the ideal speed reduction effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.
Decrease the speed and increase the output torque at the same time. The torque output ratio is the motor output multiplied by the reduction ratio, but it must be noted that the rated torque of the reducer cannot be exceeded.
Deceleration reduces the inertia of the load at the same time, and the reduction in inertia is the square of the reduction ratio.You can see that a 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 reducers, worm gear reducers , Planetary friction type mechanical stepless speed changer, etc.
