    摘要： A taper roller bearing includes: an inner ring, an outer ring, a plurality of taper rollers, and an annular cage which holds the plurality of taper rollers at an interval in the circumferential direction. The cage includes a small-diameter annular portion on one axial side, a large-diameter annular portion on the other axial side, and a plurality of column portions. An inner circumferential surface of the small-diameter annular portion includes a first inner circumferential surface portion and a second inner circumferential surface portion having a small diameter. An outer circumferential surface of the small flange included in the inner ring includes a first outer circumferential surface portion which opposes the first inner circumferential surface portion having a fine clearance, and a second outer circumferential surface portion which has a small diameter and opposes the second inner circumferential surface portion having a fine clearance.

    摘要： To provide a rolling bearing in which a spin slippage between a rolling element and a raceway groove is suppressed, and a rolling resistance is reduced to make the torque lower, whereby the rolling elements are easily incorporated even when the bearing rings are the monolithic type. Also, to provide the rolling bearing in which the rolling elements are easily incorporated even in a state where the bearing rings of monolithic type and a retainer are assembled. After the outer and inner races and the retainer are assembled, a small groove 4 for rotating the rolling element is provided in the center of an inner raceway groove 3 within a raceway groove space. The retainer 6 is only provided in one axial pocket face 7b of a pocket 7, and the other face is opened.

    摘要翻译： 为了提供一种滚动轴承，其中抑制了滚动元件和滚道槽之间的旋转滑动，并且降低了滚动阻力以使扭矩降低，由此即使在轴承圈是单片式的情况下也容易结合滚动元件。 此外，为了提供即使在组装有单片型和保持架的轴承环的状态下也容易并入滚动元件的滚动轴承。 在组装外圈和内座圈和保持器之后，在滚道槽空间内的内滚道槽3的中心设置有用于旋转滚动元件的小槽4。 保持器6仅设置在口袋7的一个轴向袋面7b中，另一个面打开。

    摘要： A bearing assembly for supporting the spindle of a machine tool includes a single row tapered roller bearing and a closure at each end of the bearing for isolating the interior of the bearing from the surrounding atmosphere. A liquid refrigerant and lubricating oil are mixed in the closure at the small ends of the rollers, and are directed into the space between the tapered raceways. This refrigerant, upon encountering the tapered rollers, the raceways along which the rollers roll, and the thrust rib against which the large ends of the rollers bear, vaporizes and extracts heat from those bearing components, thereby enabling the bearing to operate at a generally uniform temperature close to room temperature. The vaporized refrigerant flows through a port in the closure at the large ends of the rollers and then into a heat exchanger where it is condensed, the liquid refrigerant being then directed to the closure at the small ends of the rollers. The lubricating oil is likewise recirculated from the closure at the large roller ends to the closure at the small roller ends where it is again mixed with the refrigerant. The refrigerant and oil may be mixed in an inwardly opening trough carried by the cage beyond the small roller ends and may be directed through channels in the cage bridges to the outer raceway and the thrust rib.

    摘要翻译： 用于支撑机床的主轴的轴承组件包括单列圆锥滚子轴承和在轴承的每个端部处的封闭件，用于将轴承的内部与周围的大气隔离。 液体制冷剂和润滑油在辊的小端部在封闭件中混合，并被引导到锥形滚道之间的空间中。 这种制冷剂在遇到圆锥滚子时，滚子沿其滚动的滚道以及滚子的大端承受的推力肋从这些轴承部件蒸发并提取热量，从而使轴承能够以大致均匀的方式运行 温度接近室温。 蒸发的制冷剂在辊的大端部处流过封闭件中的端口，然后流入其中被冷凝的热交换器，然后液体制冷剂在辊的小端处被引导到封闭件。 润滑油同样在大辊端处的封闭件再循环到小辊端处的封闭件，在该小辊端再次与制冷剂混合。 制冷剂和油可以在由保持架承载的向内开口的槽中混合超过小的辊端，并且可以被引导通过笼桥中的通道到外滚道和推力肋。

    摘要： A flat tapered roller thrust bearing has a cage provided with axially directed lips which engage the opposed faces of the races and seal the bearing. The cage may also be provided with axially extending flanges which are shaped to enclose the outer diameter of the races so as to hold the races together.

    摘要： A cage for a radial roller bearing includes an inner cage member made of a continuous annular steel material and having a plurality of through holes, in which a plurality of rollers is housed in a corresponding one of the through holes, and an outer cage member made from resin and having a plurality of retaining holes, in which the plurality of rollers is retained such that the rollers are rollable, provided in correspondence with the through holes. The outer cage member is fixed to an outer side of the inner cage member by an axial projection-recess fitting structure.
