Method for processing face gear

Abstract

The invention discloses a processing method for realizing face gear teeth milling and high-precision teeth grinding by use of a disc cutter on an existing numerically controlled lathe, which is characterized in that a face gear 1 is installed on a working platform of the lathe, an extended grinding wheel set 4 is installed on top of a lathe spindle, the disc cutter 2 is installed on top of the extended grinding wheel set 4; during processing, the face gear 1 rotates around its axis along with a lathe A rotating shaft while swinging with a lathe B rotating shaft, the disc cutter 2 rotates at a high speed around its axis along with the spindle while making a reciprocating feed movement in the radial direction of the face gear; because of the lathe B-shaft travel limitation, a single-face processing way is adopted, a right tooth face of the face gear is processed firstly, after one whole tooth face is processed, the face gear makes an indexing motion to process the next tooth face till the whole right tooth face of the face gear is processed, and then a left tooth face of the face gear 1 is processed on another station till the whole face gear is processed. By using the existing numerically controlled lathe and the disc cutter, the face gear teeth milling and the high-precision teeth grinding can be processed at the same time without additionally designing or manufacturing a face gear special processing lathe, the manufacturing cost is reduced and the development period is shortened greatly.

Description

technical field [0001] The invention belongs to the field of face gear numerical control milling and gear grinding in the gear manufacturing method. Background technique [0002] Face gear transmission refers to the meshing of cylindrical gear and bevel gear to realize the transmission between spatially intersecting or interlaced axes. Compared with bevel gears, face gear transmission has the advantages of large coincidence, strong bearing capacity, strong stability, small vibration, and small space occupation. With the development of aerospace industry, face gear transmission has been widely used in the power plant of aircraft and occupies a very important position. [0003] Face gear processing method is one of the main tasks of face gear manufacturing. In recent years, scholars at home and abroad have done a lot of research on it. Due to the poor bearing capacity, the application of face gears can only stay in low-speed and light-load situations, which cannot meet the t...
