The temperature and pressure changes in the internal cavity of the right-angle planetary reducer directly affect its output during high-speed operation, and long-term rotation will also affect its life. The input and output ends of the IP65 protection grade planetary reducer are sealed bearings and sealing rings, which will also affect the temperature and pressure changes in the inner cavity of the reducer.

　　Temperature and pressure limit the input speed. The maximum rotation efficiency of the planetary reducer is 98%, and 2% of the input energy is consumed by heat.

　　This loss is mainly due to the friction between the sealed coil and the bearing, which increases the temperature of the inner cavity of the planetary reducer.

　　If a higher ambient temperature is used, the temperature of the inner cavity of the reducer will also increase.The temperature of the inner cavity of the reducer directly limits the output torque and output speed.

　　There are two ways to reduce the internal pressure of the right-angle planetary reducer:

　　1. Reduce the grease in the inner cavity of the planetary reducer.During long-term high-speed operation, grease may cause excessive oil temperature.

　　However, the right-angle planetary reducer should be noted that after grease makes the mobile reducer run for a period of time, this may result in a lack of grease on the sun gear and planetary gear planetary reducer, which may lead to a reduction in the load-bearing capacity of the high-speed reducer.

　　2. An air valve can be installed to transport high-pressure gas from the reducer to the outside of the reducer.However, the safety and oil leakage of the reducer should be ensured, and the waterproof, dustproof and moisture-proof functions of IP65 should not be damaged.

　　The above are two methods to reduce the internal pressure of the right-angle planetary reducer. For the planetary reducer, reducing the internal pressure can take longer.
