Process method for processing longitudinal shift cone gear on vertical milling machine

Abstract

The invention provides a process method for processing a longitudinal shift cone gear on a vertical milling machine. The process method comprises the following steps that: firstly, a first mandrel and a second mandrel are manufactured, the first mandrel is used for installing a gear sheet milling cutter and is arranged on the vertical milling machine, and the second mandrel is arranged on a center shaft of a horizontal index head of the vertical milling machine and is used for installing gear workpieces to be processed; a vertical index disc is arranged at one end of a work stable, and the index scribed line is regulated into zero; the horizontal index head is arranged on the vertical index disc surface, and the axial direction is parallel to the work stable of the vertical milling machine; the center line of the gear sheet milling cutter is a certain distance higher than the center line of the second mandrel; the vertical index disc rotates clockwise, the large end of cone teeth of the gear to be processed is used for the cutter setting and the cutter feeding, in addition, the work table is driven to longitudinally move, and a tooth groove is milled; and the horizontal index head is used for rotating a tooth angle, and the reprocessing is carried out; and the repeated operation is carried out in such a way. The process method has the advantages that the longitudinal shift cone gear can be processed on the existing vertical milling machine, the processing method is simple and practical, the time required by the gear processing is shortened, and the processing precision is high.

Description

technical field [0001] The invention relates to a processing method of a bevel gear, in particular to a process method for processing a bevel gear with tooth direction displacement on a vertical milling machine. [0002] Background technique [0003] At present, bevel gears are often used in mechanical motion to change the direction of transmission force, and the power is transmitted through the meshing of two bevel gears whose axes are not parallel, and the direction of power transmission is changed. As for the bevel gears whose addendum taper angle and dedendum taper angle intersect on the extension line of the center line of the gear shaft hole, they can be made on a special gear planer. However, for the tooth direction displacement bevel gear whose tooth root cone angle, pitch cone angle and tooth top cone angle do not intersect with the axis line, there is no special processing equipment in China, and it is very troublesome to process the tooth direction displacement b...

However, for the tooth direction displacement bevel gear whose tooth root cone angle, pitch cone angle and tooth top cone angle do not intersect with the axis line, there is no special processing equipment in China, and it is very troublesome to process the tooth direction displacement bevel gear. It takes a long time and the accuracy is not high
