Gear machined surface bearing position requirements

Gear bearing seat, a total of three sets of machining surface position between them has certain requirements, analysis is as follows: now & emsp;   1, at 80 h7 phi the inner surface of the hollow cylindrical surface, on the surface, and the chamfering, mainly for the inner surface of the phi 80 h7.     2, connected to two cylinder plane. This set of machining surface include: two long for the pit side of width is 25 and 30 and trapezoidal plane a base of 140, another side with phi 52 h7 hollow cylinder.     3, phi 52 h7 hole of the hollow cylindrical surface processing: this group of machined surface include: a phi 52 h7 on the inner surface of the hollow cylinder, surface, chamfering and 6 M6 thread hole.     4, the location of three groups of processing surface have certain requirements: two hollow cylindrical bottom surface and phi 52 h7 hole center vertical degree of tolerance of 0. 005.     Tell us by the above analysis of the bearing network, for the several groups of processing surface, can first machining surface of one group, and then use special fixture machining surface of another group, and ensure the position accuracy between them. 【 Warm prompt. 【 The bearing network] Some information from the Internet, and strive to secure timely, accurate, aims to deliver more information, does not represent our views to its approval or responsibility for their authenticity.
