Brief description reducer what does it mean

Reducer, he is actually a kind of power transmission Structural Parts that does not generate power itself, its role is to use the gear size and speed converter to reduce the number of revolutions of the motor (motor) to the number of revolutions they want; And get more torque mechanism. In the current power and motion transmission mechanism, the application range of reducer is quite wide. What the hell is a reducer? I believe that many people are the first time to hear that there may be some people have questions, the following is the small electromechanical network below to introduce you to what is the reducer? Personal arrangement is for reference only.

Some people have questions, directly adjust the motor speed is not it? In fact, the reducer gets a larger torque while changing speed. The motor is directly connected to the equipment, when the equipment is running, the load of the motor is very large, so the damage to the motor is also very large, but the reducer is not the same after, such as the reducer with a reduction ratio of 100, the load on the motor when the machine is running is only one percent, so it is not obvious. In addition, the reducer as long as the gear change is good, the cost is much lower than the motor, the motor is basically useless.

In the current power and motion transmission mechanism, the application range of reducer is quite wide. Such as gear reducer, almost all kinds of mechanical transmission systems can see its traces, from the transport of Building Materials, ships, automobiles, locomotives, heavy construction machinery equipment, bicycles, etc. are similar to the principle of the reducer, the processing equipment and automated production equipment used in the mechanical industry, to the common appliances in daily life, clocks and so on. Its application from conveying high power to conveying small load, the precise transmission point can see the application of the reducer, and in industrial applications, the reducer has the function of slowing down and increasing torque. Therefore, it is widely used in speed regulation and torque conversion equipment. For example, the elevator we do every day is the use of worm gear reducer this device.

The role of the reducer is:

1) Reduce the speed while increasing the output torque. The proportion of output torque 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 deceleration ratio. We can see that general motors have a value of inertia.

The reducer is a relatively precise machinery, the purpose of using it is to reduce the speed and increase the torque. There are many different models, and different types have different uses. There are many kinds of reducer, according to the transmission type can be divided into gear reducer, worm reducer and planetary gear reducer; According to the different transmission levels can be divided into single stage and multistage reducer; Gear shape can be divided into cylindrical gear reducer and bevel gear - cylindrical gear reducer; According to the transmission layout can be divided into expansion type, split type and coaxial reducer.

Working principle

Reducer is generally used for low speed and large torque transmission equipment, motor. Internal combustion engine or other high-speed running power through the reducer input shaft gear less meshing output shaft gear to achieve the purpose of deceleration, the general reducer will have several pairs of the same principle of gear to achieve the ideal deceleration effect, the size of the gear ratio and the number of teeth related, is the transmission ratio.
