Abstract: A railway bearing assembly comprising a rotatable axle 14 within a cylindrical bearing liner 12 in a housing is provided with a baffle 40 between the outboard end of the axle and the end of the housing. The baffle 40 defines a space in an upper end region of the housing in free communication with atmosphere by means of a breather plug 56; the shape and configuration of the baffle being such as to prevent lubricant within the housing from being violently propelled into said space during rotation of the axle in the bearing.

Abstract: A bearing, particularly a railway bearing, is described wherein a thrust disc at one end of the axle is located between axially opposed thrust faces in the bearing housing. One of the thrust faces is provided by a number of arcuate elements assembled into a circumferential groove at that end of the housing outboard of the thrust disc, the arcuate elements being located and retained in position by a spacer ring.

Abstract: A railway bearing housing has a cylindrical bore in which a cylindrical bearing liner is seated to receive a railway vehicle axle, at least one cavity being formed in the lower part of the housing and extending along the length of the housing to contain lubricant. The cavity communicates through an opening extending along the length of the housing bore with either a corresponding opening extending along the length of the bearing liner or with a number of spaced apertures in the bearing liner so that lubricant can flow through the cavity and the opening or apertures onto the rotating axle within the liner.

Abstract: Bearing bushes are made in groups or pairs by progressive press tooling so that at each stroke of the press a group or pair of bushes is produced. The bushes may have at least one end which lies in a plane inclined to the longitudinal axis of the bush, and this is effected by providing the bush blank in the flat with a sinusoidal boundary line.

Abstract: The disclosure relates to a railway vehicle bearing having a metal block with a part cylindrical recess extending around one face of the block between opposed end faces thereof. A journal bearing liner or a bearing lining extends along the recess to receive the vehicle axle for rotation. The end faces of the block are provided with thrust plates or the end surfaces of the block are provided with hardened faces to withstand thrust forces imposed by thrust faces on the axle.

Abstract: A liner element for a housing of a rotary piston machine is manufactured from a flexible metal strip and is deformed for example by pressing on one side thereof such that when the liner is assembled in a semi-cylindrical bore in the housing, the inner surface of the liner element has a trochoidal shaped surface to receive the rotor of the rotary piston machine.

Abstract: A layer of metal is cast on a surface of a metal backing and while the cast metal is still molten, a varying electromagnetic force is generated along an edge of the strip which induces electric currents in the molten metal. The resulting mechanical force exerted in the molten metal is such that the metal is restrained from flowing to the edge of the strip.

Abstract: The bearing for a railway vehicle axle comprises a bearing block of aluminium alloy having a thermal conductivity in excess of 0.20 of cal/sec/cm. cube/.degree.C. The block has a part-cylindrical bore and a bearing surface of babbitt is provided on the bore and ends of the block to support an axle of a railway vehicle.

Abstract: The disclosure relates to a bearing for a railway vehicle axle comprising a housing enclosing a bearing liner to receive an end of the axle. One end of the housing has an end cap shaped to provide an oil reservoir and there is at least one cavity in the lower part of the housing leading from the reservoir to a port in the lower part of the bearing liner to deliver lubricant to the axle end supported in the liner. The other end of the housing has an oil seal to engage the axle.

Abstract: A rotary piston machine comprising a housing having a bore to receive a three apexed rotor. The bore has a lining formed with a trochoidal surface. The lobes of the surface are formed on curved flexible metal elements and the re-entrant portions of the surface are formed on rigid bridging pieces between the ends of elements.

Abstract: A flanged half bearing has flanges connected to a bearing liner by lugs on the flanges which engage in slots in the liner edges to permit the liner to flex radially. The liner edges have abutments to hold the flanges on the liner and the inner circumferential edges of the flanged ends of the bearing are curved in profile as viewed in cross-section through the bearing axis.
