Radial anti-friction bearing, particularly cylinder roller bearing for the support of shafts in wind power gearboxes
Abstract:
A radial anti-friction bearing, which has an outer and inner bearing race with an inner and outer raceway and cylinder rollers that roll on the raceways between the bearing races and which are held at equal distances to each other in the peripheral direction by a bearing cage. To prevent slip, the cylinder rollers are replaced by hollow rollers, which have a larger outside diameter and lower modulus of elasticity. The dimensions of the bearing races, cylinder rollers and hollow rollers are configured such that both the cylinder and hollow rollers initially have a defined radial bearing clearance in the non-installed state of the radial anti-friction bearing, and the pretension necessary for the continuous drive of the bearing cage is adjusted on the hollow rollers only once the radial anti-friction bearing has been installed, while simultaneously reducing the radial bearing clearance at the cylinder rollers.
