With the development of science and technology, the development of reducer is closely related to the application history of reducer. The two are complementary. The development of the reducer makes the reducer widely used. It is precisely because the reducer is widely used that the reducer has been developed. In fact, when the reducer was born, it was valued by various engineering construction fields.
Reducer is actually a kind of power transmission mechanism, which does not generate power itself. Its function is to reduce the rotation number of motor (motor) to the required rotation number by using different gear sizes and speed converters, and to obtain a mechanism with larger torque. At present, the reducer is widely used in the transmission of power and motion. What is the reducer?
Some people have a question, is it OK to directly adjust the speed of the motor? In fact, it is not the same. When the speed of the reducer is changed, it will get a larger torque mechanism. 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 big. But after the reducer, it is different. For example, for the reducer with a reduction ratio of 100, the load on the motor when the machine is running is only one percent, which is not obvious. Besides, it's better to replace the lower gear when the reducer is replaced. The cost is much lower than that of the motor. Once the motor is broken, it's useless.
At present, the reducer is widely used in the transmission of power and motion. For example, the gear reducer can be seen in almost all kinds of mechanical transmission systems, from ships, cars, locomotives, heavy machines and tools for construction, the principle of bicycle is similar to the reducer, processing machines and automatic production equipment used in the mechanical industry, to the common household appliances, clocks and watches in daily life, etc. its application is from the transmission of large power The application of reducer can be seen in small load and precise angle transmission. In industrial application, the reducer has the function of reducing speed and increasing torque. Therefore, it is widely used in speed and torque conversion equipment. For example, the elevator we make every day uses the worm gear reducer.
The main functions of the reducer are as follows:
1) Reduce the speed and increase the output torque at the same time. The torque output ratio is multiplied by the motor output deceleration ratio, but it shall not exceed the rated torque of the reducer.
2) At the same time, the inertia of the load is reduced to the square of the deceleration ratio. You can see that the general motor has an inertia value.
The reducer is a kind of relatively precise machinery. The purpose of using it is to reduce the speed and increase the torque. It has many kinds, different models, different kinds and different uses. There are many kinds of reducers, which can be divided into gear reducers, worm reducers and planetary reducers according to the transmission type, single-stage and multi-stage reducers according to the transmission number, cylindrical gear reducers, conical gear reducers and conical cylindrical gear reducers according to the gear shape; According to the arrangement of the transmission, it can be divided into the expansion type, the shunt type and the coaxial type.
Working principle of reducer
The universal reducer is generally used for the transmission equipment with low speed and large torque. The motor, internal combustion engine or other high-speed running power can be used to reduce the speed by meshing the gears on the input shaft of the reducer with the gears with few teeth on the output shaft. The ordinary reducer will also have several pairs of gears with the same principle to achieve the ideal reduction effect. The gear ratio of the big and small gears is the transmission ratio 。
Difference with frequency converter
Universal reducer reduces the speed of motor (motor) through mechanical transmission device, and frequency converter adjusts the speed of motor (motor) by changing the frequency of alternating current. When the speed of motor is reduced by frequency converter, the purpose of energy saving can be achieved. There are three famous inverter manufacturers in China, such as TRICRYSTAL, yingweiteng, etc.
