The reducer is an independent component composed of gear transmission, worm transmission and gear-worm transmission enclosed in a rigid shell, and is often used as a reduction transmission device between the prime mover and the working machine.It plays the role of matching speed and transmitting torque between prime mover and working machine or actuator, and is widely used in modern machinery.
The reducer is generally used for transmission equipment with low speed and high torque.The motor, internal combustion engine or other power running at high speed meshes with the large gear on the output shaft through the gear with few teeth on the input shaft of the reducer to achieve the purpose of deceleration.Ordinary reducers also have several pairs of gears with the same principle to achieve the ideal deceleration effect.The gear ratio of the large and small gears is the transmission ratio.
The characteristic of the worm gear reducer is that it has a reverse self-locking function and can have a large reduction ratio.The input shaft and output shaft are not on the same axis or plane.However, it is generally bulky and has low transmission efficiency and accuracy.The harmonic reducer for harmonic transmission uses the controllable elastic deformation of flexible components to transmit motion and power, with small size and high precision.However, the disadvantages of flexsplines are their limited life, poor impact resistance and rigidity compared to metal components.The input speed cannot be too high.The planetary reducer has the advantages of compact structure, small return clearance, high precision, long life, and large rated output torque.But the price is slightly more expensive.The gear reducer has the characteristics of small size and large transmission torque.
The gear reducer is designed and manufactured on the basis of a modular combination system, and there are various motor combinations, installation forms and structural schemes.The transmission ratio is finely graded, which can meet different working conditions and realize mechatronics.The gear reducer has high transmission efficiency, low energy consumption and superior performance.Cycloidal pin gear reducer is a transmission model based on the principle of cycloidal pin gear meshing planetary transmission.It is an ideal transmission device with many advantages, a wide range of applications, and can run in both directions.
