SEAL FOR BEARINGS TO ACCOMMODATE LARGE DEFORMATIONS

摘要

A seal for a bearing has a first and a second circumference, and an anchor portion proximate to the first circumference. A span portion extends from the anchor portion towards the second circumference, and a lip extends from the span portion towards the second circumference. The lip protrudes from the span portion transversely to the span direction. A bearing and seal assembly includes a first ring and a second ring in rotatable engagement with the first ring. The first ring defines a groove and the second ring defines a contact surface. The seal is mounted in the groove, the span portion extending from the anchor portion towards the second ring, and the lip extending from the span portion towards the second ring, engaging the contact surface. The bearing and seal assembly may be used as a pitch bearing and/or a yaw bearing in a wind turbine.
