Reducer related information
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 and its purpose is to reduce the speed Shanghai Great Wall reducer worm reducer 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 pulley reduction. Machine; according to the transmission layout, it can be divided into expansion type, split type and co-axial type reducer. The reducer is an independent component consisting of a gear transmission, a worm transmission, and a gear-worm transmission enclosed in a rigid shell. It 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 the prime mover and the working machine or actuator. It is widely used in modern machinery.
A reducer is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of a motor (motor) to a desired number of revolutions and obtain a larger torque. Reducers are widely used in mechanisms currently used to transmit power and motion. Its traces can be seen in the transmission systems of almost all kinds of machinery, from heavy-duty machinery and tools used in transportation, ships, automobiles, and locomotives to construction, processing machines and automated production equipment used in the machinery industry, to common home appliances and clocks in daily life, etc. .The application of reducer can be seen from the transmission of large power to the transmission of small load. In industrial applications, the reducer has the function of reducing speed and increasing torque. Therefore, it is widely used in speed and torque conversion equipment.
1. The main functions of the reducer are:
Decrease speed while increasing the output torque. The torque output ratio is multiplied by the motor output and the reduction ratio, but be careful not to exceed the rated torque of the reducer.
, deceleration also reduces the inertia of the load. 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 in low-speed and high-torque transmission equipment to mesh electric motors, internal combustion engines or other high-speed running power through gears with a small number of teeth on the input shaft of the reducer. The large gear on the output shaft achieves the purpose of reduction. Ordinary reducers will also have several pairs of gears with the same principle to achieve the desired 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 whose purpose is to reduce the speed and increase the torque. It has a wide variety of models and different types with 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 reducers , 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 External reducer
Common types of reducers for small cranes
The main feature of the worm gear reducer is that it has a reverse automatic The lock function can have a larger reduction ratio. The input shaft and the output shaft are not on the same axis or on the same plane. However, generally the transmission efficiency is not high and the precision is not high due to larger size.
The harmonic transmission of 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 life of the flexspline is limited and it is not resistant to impact rigidity and metal parts. relatively poor. The input speed cannot be too high.
The advantages of planetary reducer are relatively compact structure, small return clearance, high precision and long service life. The rated output torque can be very large, but the price is slightly expensive.
