Abstract
A bearing assembly (12) for a rotating element (13) has one race (15) adapted to be fixed relative to ground (11) and to selectively be free for arcuate movement relative to ground. In a preferred embodiment a selective locking device (18) is provided for the relatively fixed/movable race (15).
Claims16
A bearing assembly for rotatably supporting a rotating element relative to ground and comprising:
- a race adapted to be fixed relative to ground and adapted to be freed relative to ground in arcuate movement;
- a mechanism adapted to selectively free the race which is fixed relative to ground for arcuate movement relative to ground;
- and
- an actuator adapted to move the race which is freed relative to ground arcuately.
1 more element
A bearing assembly, comprising:
- an inner race and an outer race, at least one of the inner race and outer race being selectively rotatable or locked against rotation relative to each other or a ground;
- a locking device to selectively rotationally lock or unlock at least one of the inner race and outer race relative to each other or ground;
- and
- an actuator to rotate an unlocked race.
