FLOATING WIND TURBINE BEARING SEAL WITH SYMMETRICAL PROFILE

摘要

A bearing seal assembly (110, 112, 114) seals a sealing gap (26) defined by a first race (10) and a second race (12) of a bearing (100). The bearing seal assembly includes a resilient seal (24) having a cross-sectional profile (58) that in exemplary embodiments is symmetric about at least one of a horizontal axis and a vertical axis, and which may be an X-shaped profile. The profile defines a flexing portion (55), and the resilient seal further has a first pressure-bearing side (57) and a second side (59) opposite the first pressure-bearing side. The flexing portion is configured to flex to form an energized seal that seals the sealing gap when a pressure is applied to the first side of the resilient seal. The bearing seal assembly may also include wear strip section (66) that has a removable blast shield (74) that protects the seal during a coating process, and subsequently is removed. A bearing assembly (100) may include the first race and the second race that define the sealing gap, and the described bearing seal assembly.
