测量圆锥轴上键槽宽度的对称度,一般工厂还缺乏一种适于现场使用的简易快速的适合检具。我设计制做了一种检具,包括定位环和专用卡尺两部分。图1所示是定位环,环的内孔锥度按轴的锥度配制,直径分大小各制一个,作测量基准用的端面A的位置应离键槽端头R中心1mm,小定位环的B端面离键槽端头R中心4～5mm,以便使游标卡尺的卡脚放进B端一侧的槽内。环的宽度不宜过小,以保证定心,使A、B端面对轴线的端跳误差值最小。专用卡尺如图2所示,是用普通游标卡尺
Measuring the symmetry of the keyway width on the conical shaft, the general factory also lacks a quick and easy suitable gage for field use. I made a design tooling, including the positioning ring and special calipers in two parts. Figure 1 shows the positioning ring, the inner ring taper taper shaft configuration, the diameter of the size of a system for the measurement of the end surface A position should be away from the keyway R center 1mm, a small positioning ring B end surface From the keyway R center center 4 ~ 5mm, so that the calipers Caliper feet into the B side of the slot. The width of the ring should not be too small, in order to ensure centering, so that A, B end of the axis of the terminal error of the minimum. Special caliper shown in Figure 2, is to use ordinary caliper
