Abstract

The invention discloses a machining method of a spline gear shaft in the technical field of machining. The machining method of the spline gear shaft comprises the following steps: S1: material selection: selecting a workblank of which the material adopts 20CrMnTi and the hardness is HB277-348; S2: forging: forging the workblank by adopting a horizontal forging machine; S3: normalizing; S4: turningmachining; S5: heat treatment; S6: shot blasting: mounting and fixing the spline gear shaft on a rotary table of a rotary table type shot blasting machine by adopting a positioning pin after quenching molding on the spline gear shaft is carried out, closing a shot blasting room door, and carrying out a shot blasting strengthening process; and S7: grinding: sequentially performing cylindrical grinding, gear grinding and spline grinding on the spline gear shaft after the shot blasting strengthening process is carried out. According to the machining method of the spline gear shaft disclosed by the invention, the Rockwell hardness of the spline gear shaft is greatly improved, the assembly pressure meets the assembly requirement, deformation of the spline can be effectively prevented, and thequality of the spline gear shaft is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a processing method for a spline gear shaft. Background technique [0002] The spline gear shaft is a kind of mechanical transmission, and the flat key, semicircular key, and oblique key have the same function, and they all transmit mechanical torque. There are longitudinal key grooves on the surface of the shaft, and the rotating parts on the shaft also have corresponding key grooves. Keep rotating synchronously with the axis. While rotating, some can also slide longitudinally on the shaft, such as gearbox shift gears, etc. It is widely used in the primary transmission in mechanical transmission, and the energy conversion is controlled by the spline gear shaft. It is obvious that it fully reflects its real function. The existing spline gear shaft processing method has low processing accuracy, severe spline deformation, and low service life of the spline gear shaf...
