摘要

In a roller bearing torsional connection for the machine house bearing of wind power stations, comprising two bearing track rings, roller elements rolling between these and a brake device, damping torsional vibrations of the bearing, which device comprises a brake surface connected to the one bearing track ring and a brake lining rotationally fixed to the other bearing track ring, which brake lining is pressed against the braking surface with a contact pressure force, both the braking surface (11, 18, 24) and the brake lining (12, 16, 21) in the form of circular rings extend over the entire circumference of the bearing track ring in order to improve the torsional vibration damping.
