GB10095—88《渐开线圆柱齿轮精度》等效采用ISO1328一1975《平行轴渐开线圆柱齿轮-ISO精度制》,与旧标准JB179—83主要区别如下: 1.切向一齿综合误差、陉向一齿综合误差分别改为一齿切向综合误差和一齿径向综合误差,周节偏差改为齿距偏差,不用原始齿廓或基本齿形,统一称为基本齿廓;公法线平均长度偏差代号(?)E_w改为(?)E_w(?)E_(wmo) 2.在GB10095—88中齿圈径向跳动公差F_r按两个公差计算式计算(表A1),将其计算方案中较小的一个数按优先数圆整后作为规定值。对一般规格的齿轮,公差值约压缩了20％,相当于提高一个精度等级。
GB10095-88 “involute cylindrical gear accuracy” Equivalent to ISO1328 a 1975 “parallel axis involute cylindrical gear-ISO precision system”, and the old standard JB179-83 main differences are as follows: 1. Tangential integrated error of a tooth,陉 to a tooth integrated error were changed to a tangential to the integrated error and a tooth radial integrated error, the deviation of the pitch to pitch deviation, without the original tooth profile or basic tooth shape, unified as the basic tooth profile; common normal The average length deviation code (?) E_w is changed to (?) E_w (?) E_ (wmo) 2. In the GB10095-88, the ring beating tolerance F_r is calculated according to two tolerance formulas (Table A1) Scenario in the smaller number according to the number of rounds after the round as a predetermined value. To the general specifications of the gear, the tolerance value is compressed by about 20%, which is equivalent to improving a precision grade.
