How is planetary gear reducer lubricated?

Planetary reducer is maintenance free, there is grease inside, generally do not need maintenance! Precautions for lubricating oil replacement of planetary reducer

1. The lubricant should be changed after 300-400 hours oil change, and then every 1500-2000 hours. In the harsh working environment, temperature and dust, the lubricant should be checked every half a month, and the lubricant should be cleaned to replace the lubricating oil, so as to keep the lubricating oil clean and extend the service life of the reducer. Improve economic benefits.

2. When changing the engine oil, wait for the reducer to cool down and there will be no combustion risk, but it is still necessary to keep the temperature warm, because the viscosity of the oil increases after cooling, so it is difficult to drain the oil. The output rotation direction is consistent with the input rotation direction. Series independent. Both speed reducing and speed increasing gear boxes can be called reducer (reducer or reducer). The reducer can be divided into one, two and three stages according to the number of deceleration Two stage planetary reducer refers to: the reducer has two decelerations (speed increase), and is two sets of planets, including two sun gears, two planetary carriers, two inner gear rings, two groups of planetary gears (each group of 3 or 4) to see the series. The planetary class is about 97-98%, and the parallel axis class is about 98-99.5%. The efficiency of planetary gear reducer is not necessarily higher than that of parallel gear reducer. The main reason is that the planet can be small in size.

Then the accuracy of planetary gear reducer produces the elements of return error,

The planetary reducer is analyzed as follows:

1、 Assembly error: the error occurred in the assembly of planetary reducer components, the first is the installation error between shaft and bearing, gear and shaft, and box. The larger of these errors is the base distance error, so it should be considered in the process of installation.

2、 Inherent error: the primary source of gear return error is from the error in gear processing. It is impossible to prevent the error of tooth thickness, tooth width and tooth profile in gear processing, and it can only be reduced as far as possible.

3、 Other environmental physical element error: the error of planetary reducer due to temperature rise and body elastic deformation during operation, which can be prevented by adopting relevant measures.
