Patent ID: 8328429

Claim:
A radial rolling bearing, in particular cylinder roller bearing for mounting shafts in wind power transmissions, comprising: an outer bearing ring having an inner raceway; an inner bearing ring, which is arranged coaxially with respect to the outer bearing ring, having an outer raceway; and a plurality of cylinder rollers, which roll between the outer bearing ring and the inner bearing ring on the inner raceway and the outer raceway respectively, and are held at uniform distances from one another in a circumferential direction by a bearing cage, with hollow rollers arranged between the cylinder rollers in order to avoid slip between the cylinder rollers and the outer bearing ring and the inner hearing ring, the hollow rollers have a slightly larger outer diameter and a lower modulus of elasticity than the cylinder rollers, in order to, in a load-free state of the radial rolling bearing, ensure a continuous contact with the outer bearing ring and the inner bearing ring and, thus, a continuous drive for the bearing cage and for the cylinder rollers at a kinematic rotation speed, wherein dimensions of the outer bearing ring and the inner bearing ring, the cylinder rollers and the hollow rollers are configured such that, in an uninstalled state of an assembled radial rolling bearing, both the cylinder rollers and the hollow rollers, which are formed with the slightly larger outer diameter than the cylinder rollers, initially have a defined radial bearing play, and preload on the hollow rollers required for continuous drive of the bearing cage is not set until the radial rolling bearing, is installed while simultaneously minimizing the radial bearing play at the cylinder rollers.
