Method for shaping gear shaver

Abstract

The method of shaping gear shaver includes calculating the curvature values of the practical engagement conversion point based on the curvature values of the machined gear, calculating the corresponding curvature values of the gear shaver in the engagement conversion point based on the no-side gap helical gear engagement formulation, and designing the shape correcting curve of the gear shaver precisely. The method can determine the reverse concave position range of gear shaver fast and accurately and has high shape correcting efficiency and low production cost.

Description

technical field [0001] The invention relates to the technical category of gear shaving technology in the gear manufacturing industry, in particular to a method for modifying the shape of a gear shaving cutter. Background technique [0002] As an economical and efficient gear finishing process, gear shaving has been widely used in the gear manufacturing industry. However, the gear tooth shape after shaving with a standard tooth shape shaving knife often produces a concave shape near the pitch circle, that is, the phenomenon of "shaving tooth concave", which increases the tooth shape error of the processed gear and directly leads to the gear transmission process. generate noise. At present, the effective way to solve the shaving concave in actual production is to modify the shape of the shaving cutter, that is, to modify the shape of the shaving cutter in the middle area of ​​the standard tooth shape. Since the shaving concave phenomenon is caused by the comprehensive dynami...

Problems solved by technology

Since the shaving concave phenomenon is caused by the comprehensive dynamic effect of various error factors in the shaving process, it is difficult to accurately determine the specific position and modification amount of the shaving cutter. Subjective judgment of process experience (the position is about the middle, and the concave length is basically equivalent to the concave length of the workpiece tooth surface), the modification target is poor, the number of grinding times is high, and the modification effect is poor, resulting in reduced production efficiency and high production costs for shaving.

[0003] In the relevant literature, the existing razor modification methods rely on the template modification method, the microcomputer control modification method, etc., and these methods only provide the technological method for realizing the concave modification of the shaving cutter, while the modification The specific position is determined step by step by the trial cutting method, the number of grinding times is large, and the modification effect is poor
