What kind of reducer to buy?

Reducer plays a more and more important role in the national economy, and there are more and more product categories. The common types of reducer include gear reducer, worm gear reducer, harmonic reducer, planetary reducer and cycloidal pin gear reducer. Among the many reducers, how to choose the reducer that meets your own requirements? After reading it, you will understand what kind of reducer to buy?
1. Gear reducer
The gear reducer is designed and manufactured on the basis of module combination system. There are many motor combinations, installation forms and structural schemes. The transmission ratio is graded carefully to meet different service conditions and realize mechatronics. The gear reducer has the characteristics of small volume, light weight, long service life, high bearing capacity, large transmission torque, easy disassembly and inspection, easy installation, stable operation and low noise. Gear reducer has high transmission efficiency, low energy consumption and superior performance.
2. Worm gear reducer
Worm gear reducer is a power transmission mechanism, which uses the speed converter of gear to reduce the rotation number of motor (motor) to the required rotation number and obtain a large torque. 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. Harmonic reducer
Harmonic gear reducer is a kind of gear reducer. It uses flexible gears to produce controllable elastic deformation waves, which causes the relative staggered teeth between the teeth of rigid and flexible wheels to transmit power and motion. It is composed of fixed internal tooth rigid wheels, flexible wheels and wave generators that cause radial deformation of flexible wheels. Harmonic gear reducer is a new transmission structure in gear reducer. This kind of transmission is essentially different from the general gear transmission, and has particularity in meshing theory, set calculation and structural design.
The harmonic drive of harmonic reducer uses the controllable elastic deformation of flexible elements to transmit motion and power. It has small volume, high precision and high bearing capacity. Compared with ordinary reducer, due to the use of 50% less materials, its volume and weight are reduced by at least 1 / 3. However, the disadvantage is that the flexible wheel has limited service life, is not resistant to impact, and its rigidity is poor compared with metal parts. The input speed cannot be too high.
4. Planetary reducer
Planetary reducer has the characteristics of small volume, compact structure, light weight, small return clearance, high precision, high bearing capacity, long service life, stable operation, low noise, large transmission ratio range, large output torque, large speed ratio, high efficiency and safe performance. The main transmission structure of planetary reducer is: planetary gear, sun gear and inner ring gear. The internal gear of planetary reducer adopts 20CrMnTi carburizing, quenching and gear grinding. Planetary reducer has the characteristics of power split and multi tooth meshing. It is a new reducer with wide universality. The input power can reach 104kw. The disadvantage is that the price is slightly expensive.
5. Cycloidal pinwheel reducer
Cycloid pin gear reducer is a transmission model based on the principle of cycloid pin tooth meshing planetary transmission. It is an ideal transmission device. It has many advantages, has a wide range of uses, and can run forward and backward. It can achieve high reduction ratio of 1:87 and high efficiency single-stage transmission of more than 90%. If multistage transmission is adopted, the reduction ratio is greater. The reduction ratio of primary transmission is 9 ~ 87, the reduction ratio of dual transmission is 121 ~ 5133, and the multi-level combination can reach tens of thousands. Moreover, the needle tooth meshing system has sleeve rolling friction, and the meshing surface has no relative sliding, so the primary reduction efficiency reaches 94%.


  • 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.
