Planetary reducer can be directly installed on AC DC servo motors, widely used in medium precision industrial fields, such as: printing machine tools, flame cutting, laser cutting other industries. The planetary gear motor reduces the speed while increasing the output torque, reducing the inertia of the load, the inertia is reduced by the square of the deceleration ratio. So what if the internal pressure of the planetary gear motor is too large? Speed motor manufacturers have a way.

First, the high pressure gas inside the reducer is sent to the outside of the reducer. However, it is necessary to ensure the safety of the reducer, according to environmental protection requirements, there can be no oil, oil, oil mist, etc. sent to the outside, to meet the waterproof, dustproof, moisture other protection requirements of IP65. People naturally want to add a one-way valve. However, this is suitable for planetary reducer which requires small volume large output, high rotation efficiency high reliability.

Second, reduce the grease in the internal cavity of the planetary reducer, but this affects the long-term efficient operation life of the reducer. The grease continues to move around after the reducer has been running for a period of time, making the grease on the sun wheel planet wheel of the planetary reducer as a result, the bearing capacity of the reducer is reduced when it is running at high speed, that is, the rated output torque is reduced.
