Abstract
Proposed is a novel coupling mechanism capable of applying a preload to a ball portion and a socket portion which constitute a coupling mechanism of a titling pad bearing, without using a spring element.
Claims19
A coupling mechanism for a tilting pad bearing, which couples a pad and a support in such a manner that the pad can be tilted with respect to the support, and comprises a first ball portion and a first socket portion to which a preload is applied,
- a contact surface between the first ball portion and the first socket portion serving as a first sliding spherical surface,
- the coupling mechanism further comprising a second ball portion and a second socket portion that come into contact with each other on a contact surface serving as a second sliding spherical surface,
- wherein a center of curvature of the first sliding spherical surface coincides with a center of curvature of the second sliding spherical surface.
A coupling mechanism for a tilting pad bearing, which couples a pad and a support in such a manner that the pad can be tilted with respect to the support, and comprises a first ball portion and a first socket portion to which a preload is applied,
- the first ball portion and the first socket portion being in contact with each other on a first sliding spherical surface,
- the coupling mechanism further comprising a second ball portion and a second socket portion that are in contact with each other on a second sliding spherical surface, wherein
- a center of curvature of the first sliding spherical surface coincides with a center of curvature of the second sliding spherical surface, and
- the second ball portion and the first socket portion are rigidly coupled to each other, the second socket portion and the first ball portion are rigidly coupled to each other, and the second ball portion and the second socket portion are brought close to each other, so that the first ball portion and the first socket portion are preloaded so as to be brought close to each other.
