Causes of oil leakage of planetary reducer

Planetary reducer is widely used in industrial production. But at the same time, some problems will be exposed, including oil leakage of planetary reducer, which is a common but headache problem for staff from all walks of life. Let's talk about the cause of oil leakage of planetary reducer.

1. Pressure rise in oil tank

In the closed planetary reducer, each pair of gears will generate heat when they are meshed and rubbed. According to Boyle mallott's law, with the extension of operation time, the temperature in the reducer box will gradually increase, while the volume in the reducer box will remain unchanged, so the pressure in the box will increase, and the lubricating oil in the box will splash and sprinkle on the inner wall of the reducer box. Due to the strong permeability of oil, under the pressure in the box, where the seal is not tight, the oil will seep from.

2. Oil leakage caused by unreasonable structural design of reducer

If the designed reducer does not have a ventilation hood, the reducer cannot achieve pressure equalization, resulting in higher and higher pressure in the box and oil leakage of planetary reducer.

3. Excessive refueling

During the operation of the reducer, the oil pool is stirred severely, and the lubricating oil splashes everywhere in the reducer. If the amount of oil is too much, a large amount of lubricating oil will accumulate in the shaft seal, joint surface, etc., resulting in leakage.

4. Improper maintenance process

During equipment maintenance, oil leakage will also be caused due to incomplete removal of dirt on the joint surface, improper selection of sealant, reverse installation of seals, untimely replacement of seals, etc.

The above is the reason for oil leakage of planetary reducer. In industrial production, oil leakage is inevitable. What the majority of industrial producers need to do is to pay attention at any time, pay attention at any time, avoid oil leakage accidents as much as possible and minimize industrial losses.


  • 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.
