53000型轴承采用对称球面滚子和冲压保持架,内圈取消小挡边,并以活动中隔圈代替中挡边。中隔圈的厚度不仅影响滚子的位置,而且影响轴承的调心灵活性。因此,准确地计算中隔圈的厚度,是改善或保证轴承调心性的一个关键问题。目前,53000型轴承中隔圈的工作表面(即引导滚子表面)一般为旋转圆锥面,滚子的基准面则多做成球形基面或平基面。 53000-type bearings using symmetrical spherical roller and stamping cage, the inner ring to cancel the small wall, and the activities in the ring instead of the middle wall. The thickness of the spacer not only affects the roller’s position, but also affects the centering of the bearing. Therefore, to accurately calculate the thickness of the spacer ring is to improve or ensure the bearing of a key problem. At present, 53000-type bearings in the spacer ring working surface (ie guide roller surface) is generally a rotating conical surface, roller reference surface is made of spherical base or flat base.
