Reducer introduction: The reducer plays the role of matching speed and transmitting torque between the prime mover and the working machine or actuator. The reducer is a relatively precise machine. The purpose of using it is to reduce the speed. Shanghai Great Wall Reducer Worm Reduction machine and planetary gear reducer; according to the number of transmission stages, it can be divided into single-stage and multi-stage reducers. The wheel shape can be divided into cylindrical gear reducer, bevel gear reducer and conical-cylindrical gear reducer; according to the transmission The layout can be divided into expansion type, split type and co-axial reducer. The reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid shell. It is often used as a reduction transmission device between the original moving parts and the working machine. It plays the role of matching speed and transmitting torque between the prime mover and working machine or actuator, and is widely used in modern machinery.
The reducer is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of the motor (motor) to the required number of revolutions and obtain a larger torque. Among the mechanisms currently used to transmit power and motion, reducers have a wide range of applications. Its traces can be seen in almost all kinds of mechanical transmission systems, from ships, cars, motorcycles, heavy machinery for construction, processing machinery and automated production equipment used in the machinery industry, to common machinery in daily life. Home appliances, clocks, etc. The application of reducers ranges from large power transmission to small loads and precise angle transmission. In industrial applications, reducers have the functions of decelerating and increasing torque. Therefore, it is widely used in speed and torque conversion equipment.
1. The main functions of the reducer are:
To reduce the speed and increase the output torque at the same time. The torque output ratio is based on the motor output multiplied by the reduction ratio, but be careful not to exceed the rated torque of the reducer.
, deceleration also reduces the inertia of the load, and the reduction of inertia is the square of the reduction ratio. You can see that generally motors have an inertia value.
2. Working principle of reducer:
Reducer is generally used for transmission equipment with low speed and high torque. It transmits electric motor, internal combustion engine or other high-speed running power through the input shaft of the reducer with a small number of teeth. The gear meshes with the large gear on the output shaft to achieve the purpose of deceleration. Ordinary reducers will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.
3. Types of small crane reducers:
The reducer is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. It comes in many types, with different models, and different types have different uses. There are many types of reducers. According to the transmission type, they can be divided into gear reducers, worm reducers and planetary gear reducers; according to the number of transmission stages, they can be divided into single-stage and multi-stage reducers; according to the gear shape, they can be divided into cylindrical gear reduction reducer, bevel gear reducer and cone-cylindrical gear reducer; according to the transmission layout, it can be divided into expansion type, split flow type and coaxial type reducer.
The following are commonly used reducer categories: Planetary cycloid pinwheel reducer, worm gear reducer, gear reducer, planetary gear reducer, reduction motor, continuously variable speed reducer, special purpose reducer, harmonic reducer, three-ring reducer belt Transmission Reducer Enterprise Standard Reducer (Device) Reducer Accessories Precision Reducer Combination Reducer Taiwan Foreign Reducer
Common types of reducer for small cranes:
The main feature of worm gear reducer is that it has the characteristics of reaction The self-locking function can have a larger reduction ratio, and the input shaft and output shaft are not on the same axis or on the same plane. However, they are generally larger in size, have low transmission efficiency and low precision.
The harmonic transmission of the harmonic reducer uses the controllable elastic deformation of flexible components to transmit motion and power. It is small in size and has high precision. However, the disadvantage is that the flexspline has limited life, is not resistant to impact, and is rigid. Poor compared to metal parts. The input speed cannot be too high.
The advantages of planetary reducer are relatively compact structure, small return clearance, high precision, long service life, and the rated output torque can be very large, but the price is slightly expensive.
