Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical parts, and in particular relates to a high-strength and wear-resistant spline shaft. Background Art

[0002] Spline shaft is a kind of mechanical transmission. It has the same function as flat key, semicircular key and wedge key, which are used to transmit mechanical torque. There are longitudinal keyways on the surface of the shaft, and the rotating parts on the shaft also have corresponding keyways, which can keep rotating synchronously with the shaft. While rotating, some can also slide longitudinally on the shaft, such as the gear shift gear of the gearbox.

[0003] Spline shafts are widely used, generally in the configuration of mechanical transmission in aircraft, automobiles, tractors, machine tool manufacturing, etc., while involute spline shafts are used for connections with large loads, high centering accuracy requirements, and large sizes. However, spline shafts are currently relatively fragile during use and need to be replaced after a period of use. They are not wear-resistant enough, affecting the practicality of the overall device. For this reason, we propose a high-strength and wear-resistant spline shaft. Utility Model Content
