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.

摘要: An element (20) for making an electric contact to another contact member (19) for enabling an electric current to flow between said element (20) and said contact member comprises a body having at least a contact surface thereof coated with a contact layer (21) to be applied against said contact member. This contact layer comprises a continuous film comprising a laminated multielement material having strong bonds, such as covalent or metallic bonds, within each atomic layer and weaker bonds, through larger bonding distance or for example as van der Waals bonds or hydrogen bonds, between at least some adjacent atomic layers thereof.

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: A spherical roller thrust bearing comprises two bearing rings rotatably guided by spherical roller elements for rotation about an axis. The roller elements are spaced circumferentially apart by a segmented retainer comprising separate retainer segments spaced apart in the circumferential direction. Each retainer segment includes opposite circumferentially facing surfaces engaging adjacent roller elements. Each surface includes at least one projection making point contact with a peripheral surface of a roller at a location whereby the force transmitted between the roller elements by the segments excludes a radially inward force component. The projections are located relative to the roller elements such that the segments tend to hang upon the roller elements.
