前言

本文件按照GB/T1.1—2020《標準化工作導則第1部分：標準化文件的結(jié)構(gòu)和起草規(guī)則》的規(guī)

定起草。

本文件代替GB/T25764—2010《滾動軸承汽車變速箱用滾子軸承》，與GB/T25764—2010相

比，除結(jié)構(gòu)調(diào)整和編輯性改動外，主要技術(shù)變化如下：

a）更改了適用范圍（見第1章，2010年版的第1章）；

b）更改了清潔度控制指標及測試濾膜孔徑尺寸（見8.8、9.8，2010年版的8.7、9.7）；

c）增加了摩擦力矩及其試驗方法（見8.11、9.10）；

d）更改了檢驗滾子下垂量所用塞規(guī)的通端尺寸（見9.2.2，2010年版的9.2.1）；

e）更改了檢驗滾子下垂量所用環(huán)規(guī)的通端尺寸（見9.2.3，2010年版的9.2.2）；

f）增加了出廠檢驗項目中滾子下垂量和旋轉(zhuǎn)靈活性（見10.1），型式檢驗項目中摩擦力矩（見

10.3.2）。
