Spline for high manganese steel automobile clutch and manufacturing method thereof

Abstract

The invention discloses a spline for a high manganese steel automobile clutch and a manufacturing method thereof, and belongs to the technical field of mechanical manufacturing. The spline comprises the following components in percentage by weight: 1.5-2.5% of Si, 0.5-0.75% of C, 1.2-1.8% of Cr, 6.4-7.5% of Mn, 0.26-0.52% of Ni, 0.036-0.046% of Ti, S less than 0.03%, P less than 0.018%, Zn less than 0.02%, and the balance of Fe and inevitable impurities. The plasticity and the toughness of steel are improved, so that the corrosion resistance of manganese steel is improved; a shot blasting technology is applied to remove iron oxide scales on the upper and lower surfaces of steel strips; scales can be repeatedly reduced and oxidized by electrolysis and acid washing for loosening; meanwhile, the surfaces of the steel strips generate the electrochemical reaction; and generated gas instantly blasts to peel off the loosened scales.

Description

technical field

[0001] The invention belongs to the technical field of mechanical manufacturing, and relates to a method for manufacturing a spline, in particular to a method for manufacturing a spline for a high manganese steel automobile clutch. Background technique

[0002] Generally, a clutch is a mechanical element that connects the driving shaft and driven shaft of a mechanical device to transmit power, and its characteristics require soft gear shifting and rapid and high power transmission response characteristics. These clutches are used in various industrial fields such as automobiles, motorcycles, industrial machinery, presses, and ships.

[0003] The clutch has a structure to transmit rotational force through friction between a driving gear and a driven gear, and includes a clutch disc generating friction and a splined hub connected to the clutch disc to transmit power to a drive shaft of a wheel.

[0004] Wear resistance, rigidity, and fatigue resistance are req...
