Embodiment Construction

[0066] It should be noted that the specific embodiments described below are only used to explain the present invention, but not to limit the present invention, and the present invention is not limited to this embodiment.

[0067] This embodiment provides a method for predicting tooth profile error of shaving gear, which mainly includes the following two steps:

[0068] Step one: Prediction model of tooth profile error:

[0069] S1: Coordinate transformation with installation error of shaving gear

[0070] In order to facilitate subsequent derivation, a coordinate system for gear shaving processing is established with installation errors. figure 1 Shown. Among them, S(o-xyz) and S p (o p -x p y p z p ) Are two fixed coordinate systems in space, S 1 (o 1 -x 1 y 1 z 1 ) And S 2 (o 2 -x 2 y 2 z 2 ) Are the moving coordinate system of the fixed connection between the gear shaving cutter and the workpiece gear. According to the space geometry, the conversion relationship between the coordi...

Abstract

The invention discloses a gear shaving profile error prediction method, which comprises the following steps of: introducing a gear shaving mounting error into a gear shaving motion coordinate system,constructing new coordinate conversion, deducing and calculating a compensation displacement amount caused by the gear shaving mounting error, and enabling the mode of the compensation displacement amount at a normal component vector of a contact point to be a tooth profile cut depth caused by the gear shaving mounting error. And elastic-plastic press-cutting deformation of gear shaving surface contact is given based on the contact mechanics, and the actual press-cutting deformation of gear shaving is calculated by comparing the ultimate strength of the material. And comprehensively considering the gear shaving installation error tooth profile cutting depth and the gear shaving actual pressing and cutting deformation to establish a gear shaving tooth profile error prediction model. By means of the method, prediction of the gear tooth form error of the shaved workpiece can be accurately achieved, the tooth surface precision and the machining efficiency can be effectively improved, and targeted technological guidance is provided.

Description

Technical field [0001] The invention belongs to a method in the field of gear processing, and more specifically, relates to a method for predicting gear shaving tooth profile errors. Background technique [0002] Gear shaving is an efficient process in gear finishing production, and it is an important part of ensuring the accuracy of the tooth surface and correcting gear errors. Gear shaving technology is widely used in the production of gears in machine tools, automobiles, ships, aerospace and other industries. It has the advantages of high efficiency, low cost, strong adaptability and convenient adjustment. However, the problem of tooth profile error in gear shaving is a long-standing technical problem in gear manufacturing. It is one of the main factors that cause vibration and noise in gear transmission. It not only severely affects the gear tooth surface accuracy and meshing transmission state of the workpiece, but also limits The production application of gear shaving in h...
