齿輪磨孔用夹具的类型很多,有单联齿輪、多联齿輪、圓錐齿輪磨孔夹具等。本文仅介紹行星錐齿輪(节錐角在30°左右)磨孔用的夹具。节圓偏摆是齿輪的主要精度之一,但常受磨孔加工的影响;同时由于热处理后的变形,使齿輪节圓錐与孔中心产生偏移而影响精度。为了消除热处理后的孔徑变形,并对相互位置精度給予修正,故磨孔夹具的設計要求較高。夹具体1(見附图)用螺釘固定于机床主軸法兰
Gear grinding hole with many types of fixtures, a single gear, multi-gear, bevel gear grinding hole fixture. This article describes only the planetary bevel gear (cone section cone angle of about 30 °) with the fixture. Semicircular pendulum is one of the main precision gears, but often affected by the grinding hole processing; the same time due to deformation after heat treatment, so that the gear section cone and hole center offset and affect the accuracy. In order to eliminate the heat treatment after the aperture deformation, and to correct each other’s position accuracy, so the design requirements of the grinding hole fixture higher. Clamp 1 (see attached drawing) is screwed to the machine tool spindle flange
