What are the types and functions of common reducers?

What are the types and functions of common reducers. According to the demand of reducer, different types of reducer should be selected. According to the different characteristics of reducers, different types of reducers can be divided. Common reducers include worm gear reducers; Planetary reducer; Harmonic reducer.
1、 Types of common reducers
(1) The harmonic drive of harmonic reducer uses the controllable elastic deformation of flexible elements to transmit motion and power. It has small volume and high precision, but its disadvantages are limited service life of flexible wheels, no impact resistance and poor rigidity compared with metal parts. The input speed cannot be too high.
(2) Planetary reducer has the advantages of compact structure, small return clearance, high precision, long service life and large rated output torque. But the price is slightly expensive.
(3) The main feature of worm gear reducer is that it has reverse self-locking function and can have large reduction ratio. The input shaft and output shaft are not on the same axis or plane. However, the general volume is large, the transmission efficiency is not high, and the accuracy is not high.
2、 Function of reducer
(1) At the same time, the speed reduces the inertia of the load, which is the square of the reduction ratio. You can see that general motors have an inertia value.
(2) Reduce the speed and increase the output torque at the same time. The torque output ratio shall be multiplied by the motor output by the reduction ratio, but pay attention not to exceed the rated torque of the reducer.
3、 Type of reducer
General reducers include helical gear reducers, including parallel shaft helical gear reducers, worm gear reducers, bevel gear reducers, etc., planetary gear reducers, cycloidal pin gear reducers, worm gear reducers, planetary friction mechanical stepless speed changers, etc.
The reducer is generally used for the transmission equipment with low speed and high torque. The motor, internal combustion engine or other high-speed power is meshed with the large gear on the output shaft through the gear with less teeth on the input shaft of the reducer. The ordinary reducer will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of large and small gears is the transmission ratio.

FAQ

  • Where is your product mainly exported?

    Our products are mainly exported to Japan, the United States, Germany, Southeast Asia and other countries and regions. Our customers include many OEM customers specializing in construction machinery. We have partnered with several of the Fortune 500 companies to become one of their major foundry suppliers in China.
  • How to provide goods?

    Usually we will ship the goods to the sea. The factory is only 460 kilometers away from the port. It is very convenient and convenient to transport the goods to any other country. Of course, if your cargo is very urgent, Ningbo Airport and Shanghai Airport are also nearby.
  • What is the payment term?

    When we offer you a quote, we will confirm the transaction method with you, FOB, CIF, CNF, etc. For large-scale production, you need to pay a 30% deposit before production and a 70% balance on the copy of the document. The most common way is T/T. Letter of Credit is also acceptable.
  • How to ensure the quality of your products?

    First, we will check after each process. For finished products, according to customer requirements and international standards.
  • How many employees does your company have? What is the relationship between technicians?

    We now have more than 180 employees, including 36 engineers and 28 QCs.
  • What is the ability of your company?

    We have a number of production lines with a monthly production capacity of 1,600 units and an annual production capacity of 20,000 units.
