How to solve the "Yali big" problem of planetary reducer motor

Planetary reducer can be directly installed on AC DC servo motors, is widely used in medium precision industrial fields, such as printing machine tools, flame cutting, laser cutting other industries. At the same time, the output torque is increased the inertia of the load is reduced. The inertia is reduced to the square of the deceleration ratio. So what if the internal pressure of planetary motor is too high? The manufacturer of adjustable speed motor has a way.

1、 Make the high pressure gas inside the reducer send to the outside of the reducer. However, it is necessary to ensure the safety of the reducer, according to the environmental protection requirements, no oil, oil masonry, oil mist, etc. can be sent to the outside, at the same time, it is necessary to meet the protection requirements of IP65 such as water-proof, dust-proof, moisture-proof, etc. People naturally think of adding one-way air valve. But it is suitable for planetary reducer which requires small volume, large output, high rotation efficiency high reliability.

2、 Reduce the grease in the internal cavity of planetary reducer model, but this affects the long-term efficient operation service life of the reducer. After the reducer has been running for a period of time, the lubricating grease continuously moves around, which makes the lubricating grease on the sun wheel the planet wheel of the planetary reducer. As a result, the bearing capacity of the reducer decreases at high speed, that is, the rated output torque decreases.
