292202轴承在成品装配前必须有一道轴承游隙选配工序.选配后再拆套、退磁,然后再成品装配.但由于该轴承只有一个带档边的外圈滚道(图1).在选配过程中由于离心力的作用,滚子均匀分隔在铝制保持架上,并靠向外圈内档边滚道,装配工人在拆套时必须放在工作台上反复敲打,使滚子振动,向中心方向靠拢,离开滚道位置后才能拆套拿下保持架.如果碰上外圈内径稍有过盈.就更难拆套,我厂十一车间装配工人在月末任务紧时间短的情况下,在毛主席的“鞍钢宪法”伟大红旗指引下,车间党支 292202 Bearings in the finished assembly must have a bearing clearance before mating process.Optional and then demounted, demagnetization, and then finished assembly.However, because the bearing has only one with the rim of the outer raceway (Figure 1) During the matching process, due to the centrifugal force, the rollers are evenly separated on the aluminum cage and abut the raceway on the inner side of the outer ring. When the assembly worker demolishes the assembly, they must be repeatedly beaten on the workbench to make the roller vibrate , Closer to the center direction, after leaving the raceway position to remove the holder to win the cage. If you run into the inner diameter of a slight interference, it is even more difficult to demolish, I plant eleven workshop assembly workers at the end of the task short time tight Under the circumstances, under the guidance of Chairman Mao’s “Great Red Flag of the Ansteel Constitution”, the party branch in the workshop
