Problems solved by technology

At present, most of the oil seals are directly sleeved on the sealing section of the extending shaft, and the sealing effect is not good, and there is friction and wear at the joint between the oil seal and the sealing section of the extending shaft, which shortens the service life of the oil seal

Abstract

The invention discloses a surface treatment process of an extending shaft sealing section. The process comprises the following steps that 1, copper powder is evenly laid onto the outer circular surface of the extending shaft sealing section by adopting a thermal spraying method to form a transition layer; and 2, plastic powder is laid onto the transition layer through a thermal spraying or spraying and sintering method, and a wear-resistant layer is formed. The surface treatment process has the advantages that the plastic powder adopted in the process has the self-leveling characteristic in the cooling process after hot melting, the surface of the wear-resistant layer can be smoother and flatter due to the characteristic, and the sealing effect of an oil seal on the extending shaft sealing section is improved. Besides, the plastic powder adopted in the process also has a self-lubricating property, so that when the extending shaft sealing section treated by the method and the oil seal form a sealing pair together, the frictional wear can be reduced, and the service life of the oil seal can be prolonged.

Description

technical field [0001] The invention relates to the technical field of extension shaft seals, in particular to a surface treatment process for an extension shaft seal section. Background technique [0002] Gear-shaft mechanical transmission systems are widely used in various industries. In the gear-shaft mechanical transmission system, the transmission components are mainly gears and shaft parts. These transmission components together with the transmission box, bearings and other support components, as well as seals, fasteners and other components together form a transmission system. [0003] For a pinion shaft transmission system, at least one power input shaft is required to input power to the system outside the system, and at least one power output shaft is required to output power to the outside. Due to the need for power connection with the outside, the input shaft and output The shaft end of the shaft must protrude out of the system box, because the shaft protruding o...
