笔者多年从事摩托车技术服务,经常碰到用户拿来进口旧轴承、曲轴箱、变速箱查找购买国产轴承的代用型号,现将简单的查表办法介绍事下: 首先测出进口轴承内径、外径、宽或者孔的内径、孔的高度、轴的外径,然后用国产轴承代用。我国摩托车一般采用“D”级、精密级轴承,查表2即可获得理想的轴承。级另标在轴承的外壁。 The author for many years engaged in motorcycle technical services, users often encounter imported bearings, crankcase, gearbox to find a substitute for the purchase of domestic bearing models, now a simple look-up table approach to the incident: First, measure the diameter of the imported bearings, the outer Diameter, width or hole diameter, hole height, shaft diameter, and then use the domestic bearing substitution. China’s motorcycles generally use “D” grade, precision grade bearings, look-up table 2 can get the ideal bearing. Grade another marked on the outer wall of the bearing.
