Abstract:

The air intake manifold assembly includes a manifold with a plurality of air intake ports for fluid communication with a plurality of engine cylinders, respectively, and a composite flange assembly associated with the air intake ports. The composite flange assembly is adapted to connect the air intake ports with the engine cylinders. The composite flange assembly includes a polymeric flange and a metal reinforcement member joined to the polymeric flange. The metal reinforcement member defines one or more openings and the polymeric flange is joined with the metal reinforcement member, such that at least a portion of the polymeric flange extends through the openings and forms one or more annular surfaces for contacting the engine cylinders. The metal reinforcement member may be integrally molded with the polymeric flange, or joined to the polymeric flange by interference engagement therewith. The polymeric flange may partially encapsulate the metal reinforcement member.

Appl. No.:

Assignee:

International Classification:

F16C 3346
F16C 3366

US Classification:

308214

Abstract:

The cage of a tapered roller bearing has large and small end rings that extend respectively along the large and small end faces of the tapered rollers and in addition bridges that connect the end rings and maintain the proper spacing between the rollers. Each bridge includes a web that projects radially inwardly toward the bearing cone. One end of each web merges with the small end ring, while the other end forms a corner located inwardly from the large end ring. Indeed, the corner is located opposite to the thrust rib of the bearing cone. Each web in turn is provided with a groove that extends its full length, with the end located at the small end ring being closer to the axis of rotation than the end that is at the corner. During operation of the bearing, a liquid lubricant is directed into the space between the small end ring and the bearing cone. Some of this lubricant collects in the grooves at the small end of the cage, and by reason of the centrifugal forces generated by the rotation of the cage, this lubricant flows through the grooves and at the corner is discharged against that surface of the thrust rib against which the large end faces of the rollers bear.

International Classification:

F16C 124

US Classification:

308 5R

Abstract:

A hydrostatic bearing support system is provided which comprises a bearing housing having a polygonally configured outer surface which defines at least three symmetrically disposed working faces and a plurality of pressure plates, each of which is disposed relatively opposite a corresponding working face and spaced therefrom to define a gap therebetween. A hydrostatic support film is created in the gap for supporting the housing in spaced relationship to the pressure plates.

International Classification:

US Classification:

318611

Abstract:

An object of the invention is to provide variable damping for resonant vibrations which may occur at different rotational speeds in the range of rpms in which a rotating machine is operated. A variable force damper in accordance with the invention includes a rotating mass (12) carried on a shaft (11) which is supported by a bearing (13) in a resilient cage (14). Cage (14) is attached to a support plate (15) whose rim extends into an annular groove in a housing (17). Variable damping is effected by tabs (18) of electrically conducting, non-magnetic material which extend radially from the cage (14). The tabs (18) at an index position lie between the pole faces of respective C-shaped magnets (19). The magnets (19) are attached by cantilever spring members (20) to the housing (17). By rotating the support plate (15) about the axis of shaft (11), the tabs (18) may be rotated through an angle 0 of about 40. degree.
