A bearing assembly comprises a bearing enabling a rotatable body to rotate about a rotational axis relative to a stationary body. The bearing includes a bearing inner ring and a bearing outer ring, each having at least first and second roller body tracks provided in or on non-parallel surfaces of the ring. The respective roller body tracks of the bearing outer ring are aligned with the respective roller body tracks of the bearing inner ring and a row of roller bodies is disposed between each of the respective sets of roller body tracks. At least one of the rows of roller bodies comprises one of tapered rollers and spherical rollers, at least one of the rows of roller bodies supports at least axial forces and at least one of the rows of the roller bodies supports at least radial forces.

Bearing assembly

A wind power plant comprises an outside ring, an inside ring and roll bodies arranged between an inside jacket of the outside ring and an outside jacket of the inside ring for permitting twisting or rotation of the bearing rings against one another. One of the rings on the jacket comprises an auxiliary sensor at least along a portion of the periphery. The auxiliary sensor together with the primary sensor provided in the other bearing ring are configured in such a way that a twisting or rotational position of the two bearing rings relative to one another can be detected.
