为了使一个辗压轮能够辗压数种轴承型号套圈,我们设计了一种通用辗压轮,其结构如图所示。 图中, S与A分别为轴承毛坯和活动挡圈壁厚。设计时,应使A≥S_M+5毫米,S_M是辗扩前工件的最大壁厚。a为活动挡圈1与支承辊4两者端面之间间隙,其值一般为0.3～0.6毫米,可通过调整支承辊座的位置 In order to make a rolling wheel capable of rolling several types of bearing rings, we designed a universal rolling wheel, the structure shown in Figure. In the figure, S and A are the bearing blank and the movable ring wall thickness respectively. Design, should make A ≥ S_M +5 mm, S_M is the maximum wall thickness of the workpiece before rolling. a is the gap between the end surface of the movable retaining ring 1 and the support roller 4, the value is generally 0.3 to 0.6 millimeters, and the position of the support roller seat can be adjusted
