The same is true of stepping reducers. Planetary reducer axle breakage, the reason is not single, leading to the occurrence of axle breakage has many reasons, let's see what specific.

Insufficient Strength in Design of High Speed Shaft of Stepping Reducer

Stepping reducer breaks the shaft in a short time. Fractures after axle breaking are usually relatively flat. If this happens, the planetary reducer should be replaced or the high speed shaft should not be concentric.

When the high speed axle of the reducer is not centralized, the radial load of the input axle of the planetary reducer will be increased, and the bending moment of the axle will be increased, and the axle will be broken in long-term operation. When installing and repairing, it should carefully adjust its position to ensure that the two axes are concentric. In most cases, the motor shaft will not break, because the material of the motor shaft is generally 45 steel, the motor shaft is thicker, the stress concentration is better, so the motor shaft will not normally break.

Dual motor drive is equipped with two planetary reducers and two motors on the same driving drum. When the high speed shaft of planetary reducer is designed or selected with small margin, it is easy to break the shaft. In the past, it was easy for belt conveyor to drive without hydraulic couplings, because the speed synchronization and force balance of the two motors were difficult to guarantee during start-up and operation. At present, most of the hydraulic couplings have been used to break the shaft less often, but when using the couplings should not be too much fuel, in order to make them have a limited moment effect and improve the service life of the couplings.

Excessive impurities in stepping reducer

There will be a lot of impurities in the stepping reducer. Some impurities, if they are granular impurities, will cause the formation of the gear stone. But how to make the impurities big will easily cause serious damage inside the planetary reducer, and even cause the planetary reducer axle break when it is serious. The gear box cleaner cleans the gear box by using the original oil supply and drainage system of the gear box and the filtered lubricating oil. It does not change any hardware facilities of the gear box and does not add any cleaning agent. It ensures the safe operation of the gear box and prolongs the service life of the gear box. It reduces the occurrence of axle breakage of planetary reducer.
