Process technique for processing spline tooth profiles through replacing involutes with circular arcs

Abstract

The invention discloses a process technique for processing spline tooth profiles through replacing involutes with circular arcs, which belongs to the process field of machining. The process technique is implemented by making a calculation program for replacing involutes with circular arcs which are made by an Excel of a computer, so that the results produced by replacing involutes with circular arcs can be displayed immediately just by modifying the basic parameters of spline tooth profiles. According to the invention, spline tooth profiles are processed through replacing involutes with circular arcs, so that the processing of tooth profiles is realized by using a linear cutting machine under the condition that no device such as broaching machines, slotting machines, gear-hobbing machines, and the like is used, the processing capacity is improved, the processing space is expanded, and the processing error of the process technique is just a few thousandths of an millimeter, therefore, the matching and exchanging with traditional processing tooth profiles can be realized, and the processing precision of the process technique can completely meet the application requirements.

Description

technical field [0001] The invention relates to the field of mechanical processing technology, in particular to a technology for processing spline tooth shapes with circular arcs instead of involutes. Background technique [0002] Involute spline is an important transmission connection type in mechanical transmission. It has the advantages of automatic centering, large bearing capacity, long life, easy processing, high precision, and good interchangeability. Generally, when the involute spline tooth profile is processed in batches, different types of tools are required, and correspondingly, machine tools such as broaching machines, slotting machines, and gear hobbing machines are used for processing. For small batches of parts, it is not worth the candle to make tools and find the corresponding machine tool for processing. In this case, it is very convenient and affordable to use a wire cutting machine tool for processing. However, it is more troublesome to program the in...
