High-speed temperature and pressure changes inside the planetary gearbox directly affect the output of the gearbox, and its long rotation also affects the life of the gearbox. The inputs and outputs of the planetary gearbox protection level use sealed bearings and seal rings, while affecting the internal temperature and pressure of the planetary gearbox.
The input speed of the planetary gearbox is limited by temperature and pressure, with a maximum rotational efficiency of 98% and a loss of 2% of the input energy due to heat. This is mainly due to the friction between the sealed tubes and bearings, which increases the temperature in the planetary gearbox. If the ambient temperature is relatively high, the internal temperature of the planetary gearbox will also increase. The internal temperature of the planet reducer directly limits the output torque and output speed.
Ways to reduce pressure in planetary gearboxes:
1. Reducing grease in the planetary gearbox may cause the oil temperature to be too high under long-term high-speed operation conditions, but after the gearbox is running for a period of time, the grease will move around, making the solar and planetary wheels of the planetary reducer lack grease, thus reducing the high-speed carrying capacity of the reducer.
2, the air distribution valve can be the high-pressure gas in the planetary reducer to the planetary reducer outside, but must ensure that the gas in the reducer is safe, do not leak, and will not destroy ip65 waterproof, dust, moisture and other protection functions.
Planetary gearboxes are mainly used in machine tools, robotic arms, precision testing equipment, printing equipment, textile machinery and equipment, automotive manufacturing, satellite communications, pharmaceutical industry, warehousing industry and so on. If the internal pressure of the planetary gearbox is well controlled, there will be no problem with the planetary gearbox in a few years.
