Abstract

The invention discloses a manufacturing method for a transmission shaft, and particularly relates to the technical field of machine manufacturing. The manufacturing method for the transmission shaft comprises the steps that round steel is subjected to local hot upsetting treatment to obtain a hot upsetting blank; the hot upsetting blank is drilled and turned to form an inner hole, and turning is carried out on the hot upsetting blank to reduce the diameter of the hot upsetting blank to obtain a rough turning blank; the rough turning blank is subjected to tooth extrusion forming machining treatment through using a cold extrusion tooth extrusion forming method to obtain a spline cold extrusion part with an inner spline and an outer spline; and the spline cold extrusion part is turned througha numerical control lathe to obtain a numerical control machined part, and finally, two outer circle surfaces on the numerical control machined part are ground to manufacture the transmission shaft.The technical scheme of the manufacturing method is adopted, the problem that an existing machining method for the transmission shaft is low in material utilization rate, low in production efficiency,low in dimensional precision, low in surface quality and high in production cost is solved, and the method can be used for manufacturing the transmission shaft with high precision.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a manufacturing method of a transmission shaft. Background technique [0002] The transmission shaft is one of the key parts for power transmission in various mechanical equipment. It is a slender shaft coupling with involute tooth-shaped internal splines and external splines, a minimum diameter of φ18mm, and a total length of 225mm. It is used to transmit the power in the mechanical equipment from one mechanical mechanism to another in parallel, so that the other mechanical mechanism can generate some kind of mechanical movement after obtaining power. [0003] Present drive shafts are usually manufactured by metal cutting on lathes, gear shaping machines, hobbing machines or spline milling machines. In this conventional cutting process, the outer circle and inner circle of the transmission shaft are all cut on the lathe. For the slender shaft parts such as the ...
