摘要： A tapered roller bearing has a porous rib ring against which the large ends of its wrought steel tapered rollers bear so that the ring prevents the rollers from being expelled. The rib ring is formed from porous powdered steel that has been compacted to a density of about 70% to 85% of theoretical and then sintered and machined. Thereafter, the machined rib ring is etched to expose the pores at the surface against which the large ends of the rollers bear. Finally, the rib ring is impregnated with oil. Should the bearing lose its normal supply of lubrication, the critical region of contact between the abutment face on the rib ring and the large ends of the rollers will nevertheless be adequately lubricated for a reasonable time by lubricant which escapes from the pores of the rib ring. The cage of the bearing may be piloted by the rib ring and by a ring-like cup insert that is formed in the same manner as the rib ring.
摘要翻译：圆锥滚子轴承具有多孔肋环，其锻造圆锥滚子的大端承受着多个肋环，使得环防止辊被排出。肋环由多孔粉末状钢制成，其已被压实成理论值的约70％至85％的密度，然后烧结和加工。此后，对机加工的肋环进行蚀刻以暴露出辊的大端承载的表面的孔。最后，肋环用油浸渍。如果轴承失去正常的润滑润滑，则肋环上的邻接面与辊的大端之间的临界接触区域在合理的时间内将通过从肋环孔隙逸出的润滑剂充分润滑。轴承的保持架可以由肋环和与肋环相同的方式形成的环状杯形插入件引导。

摘要： The cage of a tapered roller bearing has large and small end rings that extend respectively along the large and small end faces of the tapered rollers and in addition bridges that connect the end rings and maintain the proper spacing between the rollers. Each bridge includes a web that projects radially inwardly toward the bearing cone. One end of each web merges with the small end ring, while the other end forms a corner located inwardly from the large end ring. Indeed, the corner is located opposite to the thrust rib of the bearing cone. Each web in turn is provided with a groove that extends its full length, with the end located at the small end ring being closer to the axis of rotation than the end that is at the corner. During operation of the bearing, a liquid lubricant is directed into the space between the small end ring and the bearing cone. Some of this lubricant collects in the grooves at the small end of the cage, and by reason of the centrifugal forces generated by the rotation of the cage, this lubricant flows through the grooves and at the corner is discharged against that surface of the thrust rib against which the large end faces of the rollers bear. As a consequence, this critical surface area of the bearing receives adequate lubrication, even during high speed operation of the bearing.
摘要翻译：锥形滚子轴承的保持架具有分别沿着圆锥滚子的大小端面延伸的大小端环，并且还包括连接端环并且保持辊间适当间隔的桥。每个桥梁包括径向向内朝向轴承锥体突出的腹板。每个纤维网的一端与小端环合并，而另一端形成从大端环向内定位的拐角。实际上，角落与轴承锥体的推力肋相对。每个卷筒依次设置有一个延伸其全长的凹槽，其中位于小端环处的端部比在拐角处的端部更靠近旋转轴线。在轴承运行期间，液体润滑剂被引导到小端环和轴承锥体之间的空间中。这些润滑剂中的一些聚集在保持架的小端部的槽中，并且由于保持架的旋转产生的离心力，该润滑剂流过槽，并且在角部处被排出到推力肋的表面滚子的大端面抵靠着它们。因此，即使在轴承的高速运行过程中，轴承的这个临界表面积也会得到足够的润滑。
