Abstract
Abstract A bearing support structure in which an oil damping structure is combined with a mechanical centering structure between the oil damper and the bearing and in series with the oil damper to be effective in maintaining the rotor on its axis, the mechanical structure including a series of parallel rods surrounding the bearing and secured at one end to the fixed bearing support structure and at the other end to a ring located between the bearing and the oil damper.

Total Claims: 2
Claim 1
Independent Claim
151 words
In a bearing support construction: a fixed supporting structure; a shaft positioned within said structure; a bearing for the shaft having an outer race; a supporting ring for said outer race; an oil damping structure surrounding said ring and including an annular member having an inner cylindrical surface and having a mounting flange thereon; said supporting ring having an outer cylindrical surface located adjacent to and spaced radially inward of said inner cylindrical surface to define therebetween an oil damping space; said annular member having an inwardly extending flange at the end remote from the cylindrical surface; a plurality of rods extending from said flange to said supporting ring and secured in both; and the supporting ring being I-beam in shape with a disk portion to receive the rods and having integral cylindrical flanges one supporting the outer race and the other having the outer cylindrical surface for the oil damper.
