    摘要： The invention relates to a roller bearing having at least one row of rollers, in which the rollers are arranged at an angle to the bearing axis, an inner and an outer raceway for the rollers and a cast plastics cage for the rollers. The cage comprises two coaxial rings (1,2) and bars (3) extending between the rings, the rollers (4) being situated in pockets between the bars. In order to achieve a good positioning of the cage and a good guidance of the rollers when the cage is centered by contacting the rollers, the radial extension of the bars are greater than the radial width of the rings, whereby the bars have a portion (5) in connection to their middle part which portion extends radially inside or outside the pitch circle (6) of the rollers and contacts the rollers on a surface (7) so situated that a normal (8) through the contact of the roller surface with said surface (7) forms an angle (.alpha.) with a line (9) from the center of the bearing through the axis of the roller, the angle (.alpha.) being less than 60.degree.. Further, the cage has a portion at each end of the roller with a roller contact surface (10) so situated that a plane (11) through the contact surface (10) and the roller axis forms an angle (.beta.) with that plane (12) in which the roller is skewed when it is taking an oblique position in the cage pocket, the angle (.beta.) being less than 15.degree..

    摘要翻译： 本发明涉及一种具有至少一排辊的滚子轴承，其中辊子与轴承轴线成一定角度布置，用于辊子的内滚道和外滚道以及用于辊子的铸塑托架。 保持架包括在环之间延伸的两个同轴环（1,2）和杆（3），辊（4）位于杆之间的袋中。 为了实现保持架的良好定位和当保持架通过接触滚子居中时辊的良好引导，杆的径向延伸大于环的径向宽度，由此杆具有一部分（ 5）与其中间部分相连，该部分径向地在辊的节圆（6）的内部或外部延伸，并与表面（7）上的辊接触，使得正常（8）通过辊表面的接触与 所述表面（7）与来自轴承中心的线（9）通过辊的轴线形成角度（α），角度（α）小于60°。 此外，保持架具有在辊的每个端部处的具有辊接触表面（10）的部分，其位于使得穿过接触表面（10）的平面（11）和辊轴线与该平面形成角度（β） 12），其中当在笼形凹槽中倾斜位置时，辊倾斜，角度（β）小于15°。

    摘要： A cage for the rollers in a roller bearing in which the roller axes (2) define an angle with the bearing axis (3) has two annular portions (4, 5) and intermediate cage bars (6) defining cage pockets (7). The bars are situated radially inside of the roller axes with respect to the bearing and a flange (8) for guiding the roller by contacting their ends is extending radially outwards from one of the annular portions (4). A protrusion (9) is arranged on the flange (8) in connection to each pocket (7) or insertion into a recess in the adjacent roller end and thereby keeping the roller in the cage pocket. A recess (10) in the other annular portion (5) opposite each protrusion (9) simplifies the snapping of the roller into its pocket in the cage.
