An engine has a connecting rod with a big end dimensioned such that a lower face height is a function of an upper face height, a face-to-face width, and a strap height and width. First and second bearing shells are received by the big end under a specified clamp load to form a convex axial profile in response to the big end dimensions, and a crankshaft crank pin interfaces with the convex axial profile. A method of assembling a connecting rod includes inserting upper and lower bearing shells into a big end having a lower face height as a function of an upper face height, a face-to-face width, and a strap height and width, where each shell has a free state with a straight axial profile and uniform cross-section, and fastening a cap at a specified load to form a convex axial profile of the upper and lower bearing shells.

A vehicle seating assembly is provided which includes a seat back and a seat base operably connected to the seat back. The seat base has a seat base frame that includes a torsion tube extending laterally between at least two side members. A height adjustment mechanism is disposed through at least one of the side members. A torsion spring extends within the torsion tube and is in contact with at least two side members. A torsion spring bushing is positioned around the torsion spring and extends into the torsion tube. The torsion spring bushing defines a brush configured to contact the torsion tube and a retaining ring positioned around the torsion tube. The retaining ring is in contact with at least one side member.

A bushing structure cooperating with a shaft is disclosed. The bushing structure includes a cylindrical body and an extension portion. The cylindrical body has a shaft hole and the shaft is disposed in the shaft hole. The extension portion is disposed at one end of the cylindrical body and surrounds the cylindrical body. The cylindrical body and the extension portion are made of an iron-contained material.

A vapor compression system including a motor having a housing and a shaft having an axis, the shaft urgable into rotational movement by the motor for powering a system component. A primary bearing and a secondary bearing are positioned in the housing for rotatably supporting the shaft, the primary bearing rotatably supporting the shaft during normal system operation. A first bearing stop and a second bearing stop are positioned on opposite sides of the secondary bearing for transmitting axial forces generated along the shaft for reaction by the motor housing during abnormal system operation. At least a portion of corresponding surfaces of each of the first bearing stop and the second bearing stop facing the secondary bearing have a protective overlying layer of material applied thereto.

The bearing unit comprises: a bearing housing being formed into a cylindrical shape; and a bearing section being attached in the bearing housing. The bearing housing is made of resin. Grooves and projecting stripes are formed in an inner circumferential face of a housing hole of the bearing housing and an outer circumferential face of the bearing section, and they are extended in an axial direction. The bearing section is fitted into the bearing housing from an opening part of the bearing housing, in a state where the grooves and the projecting stripes are corresponded to each other, until the bearing section contacts an inner end face of the housing hole. A retaining projection of the bearing housing, which is formed at one end of the housing hole located on the one end side of the bearing housing, is deformed to overlap an end face of the bearing section.

A bearing arrangement for a wind turbine including a bearing housing and a drive shaft, whereby the drive shaft is arranged within the bearing housing in an axial direction along a longitudinal axis of the bearing housing, the bearing arrangement further comprising a downwind bearing and an upwind bearing as radial fluid bearings, whereby the downwind bearing and the upwind bearing are arranged between the bearing housing and the drive shaft is provided. The downwind bearing and/or the upwind bearing includes a lubricant flooded chamber, in which multiple radial bearing pads are arranged about the drive shaft, whereby the lubricant flooded chamber is sealed against the drive shaft, an internal space of the bearing housing and an outside of the bearing housing is also provided.

A sintered metal bearing is formed through sintering of a compact obtained through compression molding of raw-material powder. The sintered metal bearing includes chamfered portions that are respectively formed at least along outer rims of both end surfaces of the sintered metal bearing, and a dynamic pressure generating portion formed on an inner peripheral surface of the sintered metal bearing by sizing. An axial dimension of each of the chamfered portions is set larger than a radial dimension of the each of the chamfered portions, and a difference in axial dimension between the chamfered portions on one end side and another end side in an axial direction of the sintered metal bearing is set larger than a difference in radial dimension between the chamfered portions on the one end side and the another end side in the axial direction.

A modular plain bearing is provided. The modular plain bearing includes a first end portion having a terminal edge with a plurality of first fingers and a second end portion having a terminal edge with a plurality of second fingers. The plurality of fingers cooperatively engage to provide a snap fit connection between the parts. For longer plain bearings, a bearing extender is provided. The bearing extender includes at least a first connector having a plurality of first connector fingers. The bearing extender may include either a second connector opposite the first connector having a plurality of second connector fingers.

A washer assembly and a hydrodynamic torque converter comprising the washer assembly is provided. The washer assembly comprises a washer and a plate; the washer is annular and comprises a washer body and two or more positioning clamps protruding radially inward from an inner periphery of the washer body, at least one side of the positioning clamp in a circumferential direction having a positioning protrusion protruding; the plate is annular, an inner periphery portion of the plate being provided with two or more positioning notches; an edge of at least one side of the positioning notch in the circumferential direction being provided with a positioning groove; and the washer is mounted to one end face of the plate. The washer assembly saves the internal space of the torque converter and saves the material cost of the washer.
