轴承座孔严重磨损后,轴承的外圈就会和座孔产生相对转动,进而影响动力的传递,这种故障俗称轴承走外圆。轴承走外圆,可用手工镀铝合金加大轴承外圈尺寸的办法来修复: 1.为防止镀层脱落,使铝合金与被镀轴承外圈结合得更好,镀前须用碱水将轴承外圈上的油污除去并用清水冲洗干净,接着再用砂布将轴承外圈抛光。 2.找一根比轴承内径略小的圆钢夹在虎钳上,接着将轴承加热至60℃左右并 Bearing bore serious wear and tear, the bearing outer ring and the seat hole will have a relative rotation, thus affecting the transmission of power, this failure is commonly known as the outer ring. Bearings take the outer circle, available hand-plated aluminum alloy bearing outer ring to increase the size of the way to repair: 1. In order to prevent the coating off, so that the outer surface of the alloy with the plated bearing is better plated with alkali water before the bearing Remove the oil on the outer ring and rinse with water, then use the emery cloth to polish the outer ring of the bearing. 2. Find a slightly smaller than the bearing diameter of the steel clip on the vise, and then the bearing is heated to about 60 ℃ and
