Abstract: A bearing assembly (A1C) for installation over the journal (6,100) at the end of a railcar axle (4) has a backing ring (16,104) that seats against a fillet (10) at the end of the journal, an antifriction bearing (B1D) that fits around the journal, and an end cap (18,106) that extends over the end of the journal to retain the bearing and backing ring around the journal. In one form, the bearing (B) has two cones (32) that fit over the journal with an interference fit, with the inboard cone abutting the backing ring (16). A bore clip (22) holds the backing ring and inboard cone together in alignment before installation on the journal. In another form, a wear ring (108) is interposed between the backing ring (104) and the inner race (102) of the bearing (D), and the bore clip (22) extends between the backing ring and the wear ring. Once the backing ring and bearing are installed over the journal, the bore clip establishes a fluid barrier at the base of the fillet to prevent water from reaching and corrosion form developing at this critical area where flexure is greatest and also establishes fluid barriers with inside surfaces of the backing ring and inner race or wear ring.

Abstract: An aluminum transmission or transaxle case contains a steel shaft which is supported in the case on two directly mounted tapered roller bearings, so that the two bearings confine the shaft both radially and axially. To compensate for the differences in expansion and contraction between the aluminum case and the steel shaft as the transmission or transaxle experiences variations in temperature, a race of at least one of the bearings is fitted with a compensating ring having a coefficient of thermal expansion greater than that of the case or shaft. As a consequence, the bearings operate at a generally uniform setting over a wide range of temperature variations.

Abstract: A roller-type rock bit has a body which fits into a drill hole and is provided with inwardly directed spindles about which cone-shaped cutters revolve. Between each spindle and its cutter is a tapered roller bearing, a flat thrust bearing, and a sleeve-type radial bearing arranged in that order from the large end of the cutter. The raceways of the tapered roller bearing converge toward the small end of the cutter, and that bearing is unitized by a thrust rib located on the spindle opposite the small ends of the rollers and a rib ring which fits into the cutter opposite the large diameter ends of the rollers. Thus, a major portion of the radial load encountered in drilling is taken by the tapered roller bearing, as well as a significant portion of the thrust load, with both of those loads being transferred between the raceways generally transversely through the tapered rollers. Any thrust loading in the opposite direction is transferred between the rib ring and the thrust rib generally axially through the rollers. The rib ring further closes the end of the cutter and, together with a stream of air that flushes the interior of the cutter, prevents rock cuttings from entering the cutter and damaging the bearings.

Abstract translation: 辊型岩石钻头具有装配到钻孔中的主体，并且设置有向内定向的心轴，锥形切割器围绕其旋转。 在每个主轴和其切割器之间是从切割器的大端按顺序布置的圆锥滚子轴承，平推力轴承和套筒式径向轴承。 圆锥滚子轴承的滚道朝向切割器的小端收敛，并且该轴承由位于主轴上的与滚子的小端相对的推力肋组合在一起，以及与大直径端相对配合的切削刃 的辊子。 因此，钻孔中遇到的径向载荷的主要部分由锥形滚子轴承以及推力载荷的很大一部分所取代，其中两个载荷通过横向穿过锥形滚子在滚道之间传递。 沿相反方向的任何推力载荷通常在轴向通过辊子之间传递到肋环和推力肋之间。 肋环进一步关闭切割器的端部，并且与冲洗切割器内部的空气流一起防止岩石切屑进入切割器并损坏轴承。
