工程机械的滑轮总成由滑轮、轴承、弹簧卡圈等组成,如图1a所示。轴承镶嵌于滑轮内孔中,弹簧卡圈安装在轴承外圈两侧的凹槽内,其中弹簧卡圈为弹簧钢制成,其作用是防止轴承从滑轮1上脱落。弹簧卡圈为开口圆环,其开口两端各有一个小圆孔,用于安装时撑开弹簧卡圈。1.传统安装方法存在的问题(1)传统安装方法弹簧卡圈传统的安装方法需使用卡簧钳,如图1b所示。安装时,先将卡簧钳头部的两根突起的小圆柱插入到弹簧卡圈开口两端的小圆孔中;再用力握紧卡簧钳手柄部位,从而撑开弹簧卡
Construction machinery pulley assembly by the pulley, bearings, spring clips and other components, as shown in Figure 1a. The bearing is embedded in the inner hole of the pulley, and the spring clamp ring is installed in the grooves on both sides of the outer ring of the bearing. The spring clamp ring is made of spring steel to prevent the bearing from falling off the pulley 1. The spring clamp ring is an open ring with a small round hole at both ends of the opening for retracting the spring clamp ring during installation. 1. Problems with the Traditional Installation Method (1) Conventional Installation Method The traditional installation methods of the spring clamp ring use the clamp spring clamp, as shown in Figure 1b. When installing, first insert the two protruding small cylinders of the head of the clamp spring forceps into the small round holes at both ends of the opening of the spring clamp ring; and then forcefully grasp the handle part of the clamp spring clamp so as to distract the spring clamp
