ABSTRACT:
A heavy-duty open-center anti-friction bearing (1), especially for mounting on generator sheds in wind-powered electricity-generating plants. It comprises two races (2 and 3) with friction-reducing structures (4) rolling between them and with a brake that suppresses rotations on the part of the bearing. The brake consists of at least one braking surface (19) secured to one bearing ring (3) and of a brake lining (16) secured non-rotating to the other bearing ring (2) and forced against the braking surface by a pressure-application mechanism (21). The mechanism can be adjusted from the outside. The object is to free the bearing of normal forces deriving from the brake. The pressure-application mechanism (21) has either a wedge-shaped tip (23) or a conical tip (22) that forces two brake jaws (13 and 14) accommodated on each side of it in a continuous recess (11) in the opposite ring (3 or 9) normal to the axis (24) of the pressure-application mechanism against two opposing braking surfaces (17 and 18) in the recess.
