Reducer is a lot of national economy in the field of mechanical transmission device, industry involving product categories include all kinds of gear reducer, planetary gear reducer, worm reducer, also includes a variety of special transmission device, such as growth device, speed regulating device, and including flexible transmission device, all kinds of compound gear, etc. Products and services involve metallurgy, non-ferrous metals, coal, building materials, ships, water conservancy, electric power, construction machinery and petrochemical industries.

How should we reduce the pressure in the inner cavity of the planetary reducer?

1, make the high pressure gas inside the reducer sent to the outside. According to the requirements of environmental protection, there can be no oil, oil dirt, oil fog and so on sent to the outside, and at the same time to meet the IP65 waterproof, dustproof, moisture-proof and other protection requirements.
People naturally thought of adding a one-way air valve. But this is not suitable for small volume, large output, high rotational efficiency and high reliability.

2. Reduce the grease in the internal cavity of the model, but this affects the long-term operation and life.
The grease moves around continuously after running for a period of time, which makes the grease on the sun wheel and planet wheel. As a result, the carrying capacity decreases when running at high speed, and the rated output torque decreases.
