How to deal with the surface damage of planetary gear reducer?

The planetary reducer has 6 large gear contact surfaces with 360 degree uniform load. Multiple tooth surfaces uniformly accept the instantaneous impact load together, which can accept higher torsional impact, and the main bearing parts will not be damaged or broken due to high load.
The gear of planetary reducer has small volume and light weight. In the planning of traditional gear reducer design, multiple sets of large and fine gears are offset alternately to drive the system to reduce speed, because the reduction ratio is twice the number of two different gears, the size of the gears is the meshing relationship, and there must be a certain interval between them, so the gearbox contains a large space, In particular, when the combination of high-speed ratio needs to be combined by two or more reduction gear boxes below, the relative capacity required by the strength of structural materials is weakened, and the length of teeth can be lengthened, resulting in some huge volumes and parts.
At present, planetary gear reducer has been widely used. It should be noted that the surface of planetary gear reducer is easy to be damaged during operation. What should we do at this time?
1. The bearing is severely worn, overloaded or impacted, resulting in deformation or slight bending of the bearing of the planetary gear reducer, which will cause the rotor to sweep the inner hole. The result of the scanning chamber is that the surface of the core is scratched, the core is worn, and the winding shell is burned.
2. The silicon steel sheet at the worn part of the iron core is annealed due to friction overheating, resulting in the decrease of the permeability of the silicon steel sheet. If it is not treated in time, the eddy current will increase with the aging of the insulation of the iron core of the planetary gear reducer, resulting in the increase of the temperature rise of the planetary gear reducer, resulting in the overheating or even burning of the micromotor.
3. When the winding insulation burns the iron core surface through short circuit or arc, it is often uneven, which will not only affect the normal operation of planetary gear reducer, but also lead to short circuit between silicon steel sheets and increase eddy current in the iron core.


  • 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 provide you with a quotation, we will negotiate with you: EXW, FCA, FOB, CIF, CRF, DAP Etc. For mass production, you need to pay 30% of the deposit before production and 70% of the balance before shipment. Our most common way is T/T.
  • 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.
