Abstract

The invention relates to the field of gear shafts, and particularly discloses a wear-resistant gear shaft and a production process thereof. The wear-resistant gear shaft comprises a body, the body comprises a shaft body and a gear, the surface of the body is treated through wear-resistant coating, and the wear-resistant coating is prepared from polyurethane, polyvinyl fluoride, nano-zirconia, acetonitrile, a dispersing agent and a flatting agent. The production process comprises the following steps: S1, selecting and purchasing a blank; s2, blank heating; s3, carburizing the blank; s4, natural cooling; s5, machining; s6, deburring; s7, heat treatment; s8, preparing the wear-resistant coating; s9, spraying the wear-resistant coating; and S10, detecting. According to the wear-resistant gear shaft, the polyurethane, the nano-zirconia and the polyvinyl fluoride are added into the raw materials of the wear-resistant coating, the nano-zirconia has a certain reinforcing effect on the polyvinyl fluoride, and the reinforced polyvinyl fluoride and the polyurethane are cooperated, so that the prepared wear-resistant coating is better in wear resistance; therefore, the wear resistance of the body coated with the wear-resistant coating is improved.

Description

technical field [0001] The application relates to the field of gear shafts, more specifically, it relates to a wear-resistant gear shaft and its production process. Background technique [0002] A gear shaft is a mechanical part that supports a rotating part and rotates with it to transmit motion, torque or bending moment. [0003] For example, the Chinese utility model patent whose patent notification number is CN205244099U discloses a gear shaft, including a shaft part and a gear; The front end is a support part; a hole is opened at the end of the support part, and six threaded holes with an angle of 60 degrees are opened on the periphery of the end of the hole; the helical gear installation part is provided with a keyway for installing a rectangular key; the inside of the hole is provided with a Plastic ring mounting slot. [0004] In the related art, the degree of wear resistance of the gear shaft is relatively limited, and after a long time of operation, the wear is s...
