How to Choose Lubricating Grease for Planetary Reducer

The planetary gear reducer is composed of basic accessories such as output shaft/planet carrier, output cover, planetary gear set, input shaft, input cover/motor connection seat, etc.
In order to achieve the best effect of the planetary gear reducer during operation, we need to add lubricating grease between the gear tooth meshing surfaces to avoid direct contact of the gears, reduce friction losses, improve transmission efficiency, improve the working condition of the gears, and maintain Proper operation and expected life.

The effect of lubricating oil on reducer

As an important part of the mechanical transmission device, the reducer is responsible for converting high-speed rotating power into low-speed and high-torque output. During the operation of the reducer, friction and wear are inevitable problems, and lubricating oil plays an important role, which can effectively reduce friction and wear, extend the service life of the reducer, and improve work efficiency.
 

First, lubricating oil can form a uniform lubricating film

The lubricating oil can form a uniform lubricating film, reducing direct contact between metal surfaces and reducing the friction coefficient, thereby reducing energy loss and improving transmission efficiency. At the same time, the lubricating film can also absorb and disperse the heat generated by friction, effectively reduce the temperature of mechanical parts, slow down the wear rate, and extend the service life of parts.
 

Secondly, lubricating oil can also prevent corrosion and oxidation of reducer parts

During operation, mechanical parts are easily affected by the external environment, such as humid air, acid and alkali substances, etc., which can easily cause corrosion and oxidation on the metal surface, thus affecting the normal operation of the machinery. The antioxidants and preservatives in lubricating oil can effectively prevent these chemical reactions from occurring and protect the surfaces of mechanical parts from corrosion and oxidation.
 

In addition, lubricating oil can also effectively clean impurities and metal shavings inside the reducer

During the operation of machinery, the friction between parts will produce metal shavings and impurities. If these impurities cannot be removed in time, they will increase the wear of mechanical parts and affect the normal operation of the reducer. The detergents and dispersants in lubricating oil can effectively remove these impurities and metal shavings, keep mechanical parts clean and reduce wear.
 

In short, lubricating oil plays a very important role in the reducer

It can effectively reduce friction and wear, extend the service life of mechanical parts, and improve work efficiency. Therefore, when using the reducer, attention must be paid to timely replacement of lubricating oil, and regular inspection and maintenance of the lubrication system to ensure the normal operation of the reducer.

So what should we pay attention to when selecting lubricating grease for planetary gear reducers and what kind of lubricating grease should we choose? Fubao reducer manufacturer will announce it to everyone.

The selection of gear lubricating grease is related to the temperature of the environment in which the planetary gear reducer is used. The higher the temperature, the lower the viscosity of the lubricating oil, so we need to choose lubricating grease of different viscosities according to different temperatures.

At the same time, it is also necessary to consider that temperature differences in different seasons will produce different viscosity of oil. Of course, it is also necessary to consider the temperature rise effect of the planetary gear reducer under working conditions. The higher the power of the reducer gear, the greater the temperature rise, the longer the working time, and the higher the heat. Under high temperature conditions, the viscosity of lubricating grease will increase. The consistency will decrease.

Fubao recommends that when selecting lubricating grease for planetary gear reducers, the following should be considered: load properties, size, gear material and operating speed of the gear reducer. Heavy-duty gear transmission can use lubricating grease with high viscosity, good lubricity, and strong anti-wear properties. Open gear transmission can choose lubricating grease with good corrosion resistance, anti-oxidation and anti-wear properties, and strong adhesion. Since the worm drive is not conducive to the formation of oil film, lubricating grease containing both extreme pressure additives and oily additives can be used. For transmission parts with light load, high speed and intermittent operation, lubricating grease with lower viscosity can be selected.
