Filed:

Jan 31, 2003

Appl. No.:

11/656355

Inventors:

Edward C. Axler - Bloomfield CT, US
Edward P. Butler III - Torrington CT, US

Assignee:

Timken US Corporation - Torrington CT

International Classification:

F16C 33/58

US Classification:

384620, 384622

Abstract:

A thrust bearing assembly comprising first and second thrust race members () and a roller assembly () positioned therebetween. The first thrust race member () includes a radial race surface (), a flange extending from the race surface and a radial lip () extending radially beyond the flange (). The second thrust race member () includes a radial race surface () and a piloting flange extending from the race surface and includes a retaining lip (). The second thrust member () is positioned within the first thrust member () radial lip () and retained thereby and there is a clearance between the retaining lip () and the first thrust race member flange () external surface.

US Classification:

384/621000

Abstract:

A thrust bearing assembly including a plurality of rollers having a given diameter d, a cage assembly configured to support the rollers, the cage assembly having a first radial edge that extends a given radial distance X beyond the rollers, and at least one thrust race member. The thrust race member includes a radial race surface, a radial flange extending from the race surface, and a radial lip extending from the flange. The lip is substantially parallel to and at a distance less than the given diameter d from the race surface. The lip has a free end at a distance from the flange greater than the given distance X.

US Classification:

Abstract:

An oscillating bearing is disclosed for a variable-displacement axial piston hydraulic machine having a swashplate with a convex semi-cylindrical bearing face with provisions for attaching the oscillating bearing, and a housing with a concave semi-cylindrical bearing saddle. The oscillating bearing includes thin outer and inner race members having centered openings and formed in arcs congruent with the concave surface of the bearing saddle of the housing and the convex bearing face of the swashplate, respectively. The outer race member has support means on at least one axial end for supporting a timing member which engages a timing feature of the swashplate and synchronizes motion for all parts of the oscillating bearing, and the inner race member has means for holding the inner race against the convex bearing face of the swashplate. A separator is interposed between the inner and outer race members, the separator being formed in an arc having inner and outer surfaces parallel to the proximal surfaces of the race members, the separator also having an axially centered opening and two additional substantially rectangular openings axially spaced from the axial ends of the separator and the centered opening. The additional openings serve as pockets for anti-friction rollers.
