AXIAL ANGULAR-CONTACT ROLLING BEARING, IN PARTICULAR FOR ROTARY TABLE MOUNTING ON MACHINE TOOLS, AND METHOD FOR ASSEMBLING AN AXIAL ANGULAR-CONTACT ROLLING BEARING OF SAID TYPE

摘要

The invention relates to an axial angular-contact rolling bearing (1) which is composed substantially of a single-piece inner bearing ring (2) and of a single-piece outer bearing ring (3) and of a multiplicity of rolling bodies (6, 7) which are arranged adjacent to one another in at least two rows (4, 5) between the bearing rings (2, 3) and which are held at uniform intervals to one another in the circumferential direction by at least two bearing cages (8, 9) and which roll under defined contact angles with their running surfaces on at least two raceways (12, 13) arranged next to each other on the outer side (10) of the inner bearing ring (2) and on the inner side (11) of the outer bearing ring (3). According to the invention, one of the at least two rows (4, 5) of the rolling bodies (6, 7) is formed by bearing balls, while the other of the at least two rows (4, 5) of the rolling bodies (6, 7) is composed of spherical rollers, each having two side surfaces (14, 15) flattened symmetrically proceeding from a spherical basic shape, wherein the inner bearing ring (2) has a single radial filling bore (16) arranged axially eccentrically adjacent to one of the two raceways (12, 13), through which radial filling bore (16) all of the rolling bodies (6, 7) of the at least two rows (4, 5) can be filled into their raceways (12, 13), and wherein the respective bearing cages (8, 9) of the at least two rows (4, 5) of the rolling bodies (6, 7) are formed as segmented cages composed of a plurality of juxtaposed identical cage segments (17, 18). The invention also relates to a method for assembling an axial angular-contact rolling bearing (1) designed according to the invention.
