Abstract
Abstract A bearing support structure in which the outer bearing race is in a support ring surrounded by an outer damper ring to form an oil damper space therebetween. At one end of the support ring is a projecting flange to which one end of each of a ring of rods is secured. This ring of rods surrounds the outer damper ring and is secured at the other end of the rods to the remote end of the outer damper ring. The inner end of the damper ring is supported from a mounting flange by a frusto-conical member having holes therethrough for the rods.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
168 words
In a bearing structure: a fixed support structure; a shaft; a bearing for the shaft having an outer race; a supporting sleeve for the outer race having an outwardly extending flange thereon; an outer damper sleeve surrounding said supporting sleeve and being spaced therefrom to provide an oil damping film; a frustoconical element extending outward from the end of said outer sleeve adjacent the flange on the supporting sleeve, said element also having a flange at its outer end for attachment to the fixed support structure; a plurality of parallel rods arranged in a ring around the outer sleeve; an end flange on the end of said outer sleeve remote from the frustoconical member and remote from the flange on the supporting sleeve; and said rods being secured at one end to said end flange and at the other end to the flange on said supporting sleeve, said frustoconical element having openings through which the rods extend, with the flange on the element outside the plurality of rods.
Claim 2
Dependent Claim
168 words

Claim 3
Dependent Claim
28 words
A structure as in claim 1 in which said rods are secured by brazing to said supporting sleeve flange and in the end flange on the outer sleeve.
Claim 4
Dependent Claim
25 words
A structure as in claim 1 in which the race supporting sleeve has spaced seals on its outer surface to define the oil damping space.
Claim 5
Dependent Claim
23 words
A structure as in claim 1 in which the rods are all parallel to the axis of the shaft and uniformly spaced therefrom.
