Problems solved by technology

However, if the conventional induction hardening method is adopted, since the induction hardening is much higher than the base of the pin shaft, after the pin shaft is bent under load, the surface is prone to cracks, and fatigue fractures often occur during use.

Abstract

The invention discloses a wear-resisting pin shaft which comprises a pin shaft body.The outer surface of the upper portion of the pin shaft body is provided with an induction quenching layer, and the two ends of the lower portion of the pin shaft body are each provided with a gap.In this way, the wear resistance of the pin shaft is improved; meanwhile, after the pin shaft bears loads to be bent, the surface of the pin shaft body is not prone to cracks, fatigue fractures occurring in the using process are reduced, and the service life of the wear-resisting pin shaft is prolonged.

Description

technical field [0001] The invention relates to an improvement of a pin shaft, in particular to improving the wear resistance of the pin shaft; at the same time, after the pin shaft is bent under load, the surface of the pin shaft body is not prone to cracks, reducing fatigue fractures during use; increasing the use of Long life wear-resistant pin. Background technique [0002] The pin shaft is one of the parts on the chain. The pin shaft of an ordinary chain is usually quenched and tempered as a whole. Chains used in special environments, in order to improve their wear resistance, also have surface induction hardening treatment. However, if the conventional induction hardening method is adopted, since the induction hardening is much higher than the base of the pin shaft, after the pin shaft is bent under load, cracks are easy to occur on the surface, and fatigue fractures often occur during use. Contents of the invention [0003] The technical problem mainly solved by t...
