采用加强型筐形保持架的圆锥滚子轴承有一系列优点。由于普遍增加了滚子的数量和长度,显著提高了轴承的计算寿命;同时在设计中考虑了轴承零件的通用性,为降低成本、缩短生产周期创造了有利条件。 加强型筐形保持架的特点是:重量轻、工作性能和润滑性能都较好,如增加了保持架窗孔的数量和长度,窗孔过梁采用角度压坡,保持架选用外径和外侧角作基准,减小钢板的厚度以及要求表面进行磷化处理等。同时,对保持架的技术条件、检查项目比过去的标准有所提高;有些项目是新增加的,如径向游动量等。
Tapered roller bearings with reinforced cage cages have a number of advantages. As a general increase in the number and length of the roller, the bearing significantly increases the calculated life expectancy; the same time, bearing in mind the design of the common parts, in order to reduce costs and shorten the production cycle has created favorable conditions. Reinforced basket cage features are: light weight, work performance and lubrication performance are better, such as an increase of the number and length of the cage window, window beam angle angle slope, the cage used outside diameter and outside As a benchmark for reducing the thickness of the steel plate and phosphating the surface. At the same time, the technical conditions of the cage, inspection items than the previous standard has improved; some items are new, such as the amount of radial swimming and so on.
