Speed reducer, he is actually a power transmission mechanism itself does not produce power, its role is the use of gear size and speed converter, the motor (motor) to reduce the number of revolutions to their desired number of revolutions; and get more Large torque mechanism. In the current institutions for the transmission of power and movement, the scope of application of reducer is quite extensive. What is reducer in the end? I believe many people are the first time I heard that there may be some people have questions, the following is million small mechanical and electrical network below will introduce you in the end what is reducer? Personal finishing for reference purposes only.
Some people have questions, the direct adjustment of the motor speed is not it? In actual fact, the reducer in the change of speed and get a larger torque body. Motor directly connected to the device, when the device is running, the motor load is very large, so the damage to the motor is also great, but after the reducer is not the same, such as the reduction ratio of 100 reducer, the machine running When the load on the motor only one percent, so it is not obvious. Besides, as long as the gear reducer change gear is good, the cost is a lot lower relative to the motor, the motor is basically a useless ah.
In the current institutions for the transmission of power and movement, the scope of application of reducer is quite extensive. Such as gear reducer, almost all kinds of mechanical transmission system can be seen in its tracks, from the transport of ships, cars, locomotives, heavy construction machinery and equipment, bicycles and the principle is similar to the reducer, the machinery industry used The processing equipment and automated production equipment, to daily life common appliances, watches and clocks, etc. Its application from the transmission of large power to small loads, the precise point of transmission can see the application of reducer, and in industrial applications On the reducer with deceleration and increase torque function. Therefore widely used in speed and torque conversion equipment. For example, we do the elevator every day, is the use of worm gear reducer this device.
The role of reducer are:
1) Decrease speed and increase the output torque at the same time. The proportion of torque output should be multiplied by the output of the motor, but be careful not to exceed the rated torque of the reducer.
2) Deceleration also reduces the inertia of the load, reducing the inertia to the square of the reduction ratio. We can look at the general motor has a value of inertia.
Reducer is a relatively sophisticated machinery, the purpose of using it is to reduce speed, increase torque. It's a wide range of different models, different types have different uses. A wide range of reducer, according to the type of transmission can be divided into gear reducer, worm reducer and planetary gear reducer; according to the transmission of different levels can be divided into single-stage and multi-stage reducer; Gear shape can be divided into cylindrical gear deceleration Conical gear reducer and cone - cylindrical gear reducer; According to the transmission layout can be divided into the expansion type, split and coaxial reducer.
working principle
Reducer is generally used for low speed and high torque transmission equipment, the motor. Internal combustion engine or other high-speed operation of the power through the reducer input shaft gear less gear meshing output shaft gear to achieve the purpose of deceleration, the general Reducer will have several pairs of the same principle gear to achieve the desired deceleration effect, the size of the gear ratio of the number of teeth, is the transmission ratio.
the difference
The reducer reduces the motor (motor) speed by a mechanical transmission, and the frequency converter achieves the motor (motor) speed adjustment by changing the AC frequency. Through the inverter to reduce motor speed, you can achieve the purpose of saving energy. The more famous domestic inverter manufacturers have three crystal, British Witten and so on.
