Abstract
A rotary bearing assembly having a preset breaking point, particularly for a rotor of a turbo engine, includes a rotary bearing arranged between a nonrotating bearing carrier housing and a bearing carrier rotating about a rotational axis, the rotary bearing being fixed radially and axially at its outer bearing ring via a first tangential plane and a second tangential plane in the nonrotating bearing carrier housing. At predetermined stress, a breaking arrangement for the formation of a preset breaking point is provided, which is arranged in the first tangential plane and the second tangential plane, concentric with the rotational axis, between the outer bearing ring and the nonrotating bearing carrier housing.
Claims22
A rotary bearing assembly, comprising:
- a non-rotatable bearing carrier housing including a first tangential plane and a second tangential plane;
- a bearing carrier rotatable about a rotational axis;
- a rotary bearing including an outer bearing ring and arranged between the non-rotatable bearing carrier housing and the bearing carrier and radially and axially fixed at the outer bearing ring via the first tangential plane and the second tangential plane;
- and
- an arrangement configured to form a preset breaking point at a predetermined stress, the arrangement disposed in the first tangential plane and the second tangential plane concentric with the rotational axis between the outer bearing ring and the non-rotatable bearing carrier housing.
