How to effectively control the oil leakage is of concern to people. For example, the oil splashing on the inner wall of the box needs to flow back to the oil sump in the box as soon as possible. The oil return groove of the rectangular section on the threaded surface of the cycloidal pinwheel reducer case can make the oil splashed on the inner wall of the box cover drip along the inner wall, collect in the oil return groove, and then flow back to the oil pool.The oil leakage of the cycloidal pinwheel reducer is one of the common faults of the cycloidal pinwheel reducer, and it is a headache.
In order to prevent the oil from leaking gradually to the outside of the box along the shaft head, the shaft head adopts an oil groove type sealing device, and the oil return oil is opened at the lower end of the oil groove to allow the oil accumulated in the oil groove to flow back into the box Helical Gearbox Manufacturers to prevent leakage. Therefore, the inner wall of the cycloid reducer case cover is made into an arc shape to prevent the oil from staying at the shaft sealing device.
Whether the oil return of the cycloidal pinwheel reducer is smooth is also an important factor for the oil leakage of the cycloidal pinwheel reducer. The individual oil return grooves of the box seat of some cycloid reducers are too small, which cannot really play the role of return flow. The size of the return groove can be determined according to the design needs. The smooth flow of oil return is to make the oil that may leak from the outside flow back into the tank relatively smoothly
