X294仪器压板的改进设计

Improvement design on X294 instrument clamp

通常圆柱滚子轴承径向游隙是在X294仪器上采用手推法进行测量,根据圆柱滚子轴承的结构特点,测量时,需用压板将被测轴承内圈固定进行测量。一个压板对应一种型号的轴承,使得压板数量多,换活测量不方便。采用改进后的压板,改变了一个压板对应一个轴承型号的历史,大大提高了压板的测量范围,且使用调整方便,可节约大量成本。

The radial clearance of cylindrical roller bearing is measured usually on the X294 instrument by the hand-push method, based on structural characteristics of cylindrical roller bearings, radial clearance is measured after clamp fixing bearing inner ring. The history of a clamp corresponding to a bearing type is changed by using the improved clamp to greatly enhance the measurement scope of clamp, easy to adjust, and can save significant cost.
