Background

The planetary reducer has the advantages of small volume, light weight, strong overload capacity and the like, and under the same transmission power, the volume of the planetary reducer is only about 40% of that of the parallel shaft reducer, but the self heat dissipation area of the housing of the planetary reducer is smaller than that of the parallel shaft reducer, and the natural heat dissipation capacity of the housing of the planetary reducer is poorer. When the heat generated during continuous operation of the planetary reducer is greater than the heat dissipation capacity of the reducer shell, the temperature of the reducer is higher, so that the internal lubricating oil fails due to overhigh temperature.

The scheme that the existing cooling effect is better is that a set of oil circulation cooling system is added outside the speed reducer, lubricating oil in the speed reducer is pumped out and cooled and then is supplied into the speed reducer by an oil pump, but the scheme has obvious defects that the requirement of oil lubrication on a sealing element of the speed reducer is very high, and the sealing element is easy to leak oil and pollute the working environment after being worn.
