It plays the role of matching speed and torque transmission 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, and to drive the worm reducer and planetary gear reducer. It can be divided into single-stage and multi-stage reducer according to the number of transmission stages. The shape of the factory wheel can be divided into cylindrical gear reducer, bevel gear reducer and cone-cylindrical lead gear reducer. -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 housing. It is often used as a reduction transmission between the prime mover and the working machine. It plays the role of matching speed and torque transmission between the prime mover and the working machine or actuator, and is widely used in modern machinery.
The speed reducer is used first because of the speed reduction. The speed reducer is of course used for speed reduction. Commonly used power source-motor. Generally, the speed of a four-pole motor is 1400 rpm (provided that the frequency will affect the speed of the motor. This applies to inverters), but your working machine does not need to be so fast. If you use inverters, there are many restrictions. No matter whether the frequency becomes lower or higher, it will cause voltage changes, which will cause the motor output power to become lower. , And can not be used for a long time, the motor is easy to burn out. Secondly, from the formula P = (V * M) / (9550 * η), we can know that under the condition of fixed power and efficiency, the speed and torque are inversely proportional. At the same time, greater torque will be obtained, that is, you can use a smaller prime mover to drive a larger working machine; at the same time, the reducer can also meet your needs for commutation. Many machines and equipment are designed due to installation space. Reasons and other reasons, the installation form is special, at this time a suitable reducer can meet all your needs. In general, the fundamental purpose of using a reducer is to transmit (transmit power). The biggest purpose is to reduce the speed and obtain greater torque. Others, including commutation, can be considered the purpose. Reducers are everywhere in life. It's as big as a train ship, as small as a toy watch, and it's everywhere.
