How to judge whether the oil return of the reducer is smooth?

The smooth flow of oil return is to enable the oil that may leak outside to flow back into the tank relatively smoothly.For example, the oil splashed on the inner wall of the box needs to flow back to the oil pool in the box as soon as possible, so the inner wall of the gear box cover is made into an arc shape, in order to prevent the oil from staying at the shaft head sealing device to prevent oil Leakage gradually to the outside of the box along the shaft head. The shaft head adopts an oil ditch type sealing device. The lower end of the oil ditch is provided with oil return, so that the oil accumulated in the oil ditch can flow back to the box to prevent leakage.

  The oil return groove with rectangular section on the joint surface of the reducer chassis can make the oil splashed on the inner wall of the box cover drip down along the inner wall, collect into the oil return groove, and then flow back to the oil pool.The size of the return groove can be determined according to the design needs. The individual oil return grooves of the box seat of some reducers are too small and cannot really play the role of backflow.
