During the high-speed operation of the step planetary reducer, the temperature and pressure changes in the internal cavity directly affect its output, and long-term rotation will also affect its life.
Temperature and pressure limit the input speed. The large 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 internal cavity of the gearbox will also increase. The temperature of the internal cavity of the reducer directly limits the output torque and output speed.
There are two ways to reduce the internal pressure of the planetary reducer
1. Reduce the grease inside the step planetary reducer. During long-term high-speed operation, grease may cause the oil temperature to be too high. However, it should be noted that after the mobile reducer is operated by grease for a period of time, this may lead to a lack of grease for the sun gear and planetary planetary reducer, which may lead to a reduction in the carrying capacity of the high speed reducer.
2. A gas distribution valve can be installed to deliver high-pressure gas from the reducer to the outside of the reducer. However, the safety of the reducer should be guaranteed, and the waterproof, dustproof and moisture-proof functions will not be damaged.
