Abstract

The invention discloses a spline transmission shaft and a machining technology thereof. The spline transmission shaft comprises a cylindrical main shaft, wherein threaded holes are formed in the central axis directions of the two ends of the main shaft; a first spline and a second spline are formed in the surfaces of the two ends of the main shaft; an annular limiting ring and a limiting table arearranged between the first spline and the second spline; the limiting table is close to the first spline; the limiting ring is close to the second spline; and one end, close to the second spline, ofthe limiting ring is provided with an annular limiting groove. According to the spline transmission shaft, the threaded holes are formed in the two ends of the main shaft, the spline transmission shaft is fixed through the matching of screws and the threaded holes, the installation is simple, the disassembly is convenient, the assembly process of the transmission shaft is greatly facilitated, thelimiting ring and the limiting table perform the function of limiting, the assembly is simple; and in addition, the splines are arranged at the two ends of the main shaft, and the splines are matchedwith a driving device and an impeller, so that the transmission is stable and the safety is high.

Description

technical field [0001] The invention relates to the technical field of transmission shafts, in particular to a spline transmission shaft and a processing technology for the spline transmission shaft. Background technique [0002] The structure of the existing spline transmission shaft is composed of the outer diameter and the spline, and the product has high requirements on the dimensional accuracy, shape tolerance and roughness of the assembly outer diameter and the spline. The general processing technology is as follows: blanking---rough turning large end---rough turning small end---finishing large end---finishing small end---knurled key---heat treatment--- --Grinding center hole--cylindrical grinding--cleaning, the disadvantages of the existing processing technology are as follows: 1. The process is scattered and the stability of product quality is poor. 2. The product turnover time is long and the turnover inventory is large. 3. The equipment occupies a large area, and...
