JB179—60圆柱齿轮公差标准中,允许采用公法线长度变动量ΔL_g(以下皆用符号表示)与齿圈径向跳动Δe_j组合评定齿轮的运动精度。而目前国外的圆柱齿轮公差标准,除苏联和东德外,全都不直接采用ΔL_g这项指标。对此,国内颇有争议。诸如ΔL_g能否如实反映齿轮的切向误差?它和Δe_j是否真正互相独立,互不影响?总之用ΔL_g作为评定齿轮运动精度的一项指标是否合适?对上述问题,我们在调查的基础上,着重对ΔL_g超差严重
JB179-60 cylindrical gear tolerance standards allow the use of common-law line length changes ΔL_g (the following are signs) and the ring gear beating Δe_j combined assessment of the accuracy of gear movement. At present, the standard of cylindrical gear tolerance in foreign countries, except the Soviet Union and East Germany, does not directly adopt the indicator of ΔL_g. In this regard, the domestic quite controversial. Such as ΔL_g can accurately reflect the tangential error gear? It and Δe_j really independent of each other, without affecting each other? In short with the ΔL_g as a measure of gear accuracy is an indicator of the above problems, we based on the investigation, Focus on the ΔL_g serious difference
