1, improve the breathable cap and check the hole cover.
2, smooth flow: in order to be thrown by the gear on the bearing excess lubricant does not accumulate at the shaft seal, it is necessary to make excess lubricant flow back to the oil tank in a certain direction, that is, to achieve smooth flow. Specifically, the lower tile center of the housing to open a tilt to the machine return tank, at the same time at the end cover straight open a gap, the gap is directed to the return tank, so that the excess lubricant through the gap, the return tank flow back to the oil tank.
3, improve the shaft seal structure.
4, the use of new sealing materials.
5, conscientiously carry out the maintenance process.
6, wipe: planetary gearbox static sealing point through the treatment, generally can be achieved without leakage, but the dynamic seal point due to seal aging, poor quality, improper assembly, shaft surface roughness and high reasons, so that individual dynamic sealing point still has a small leakage, due to poor working environment, coal dust glued to the shaft, appear oily, so need to stop running, wipe the oil on the shaft.
