Block And Cap Type Patents (Class 384/434)
  • Patent number: 5050544
    Abstract: A structure for mounting the same type of camshafts on two different types of cylinder heads which have reversed order of intake valve/exhaust valve arrangement, the same type of camshafts being mounted on the two types of cylinder heads so as to be staggered longitudinally by an amount delta. In the structure, thrust planes formed in the two types of cylinder heads also are staggered with respect to each other by the amount delta. Further, a single type of thrust bearing cap is provided which has a bolt hole spaced longitudinally from the transverse centerline of the bearing cap by one-half the amount delta. The bearing cap mounted to one type of cylinder head is in reversed orientation relative to the bearing cap mounted to the other type of cylinder head. This structure enables common use of the same camshaft manufacturing line and the same engine assembly line for the two types of cylinder heads.

  • Patent number: 4884900
    Abstract: A light metal component formed in a single piece and which has an aperture in the component, the aperture being entirely surrounded by the metal of the component, wherein a fracture zone is incorporated in the metal surrounding the aperture, with a brittle material incorporated in the component at the fracture zone so that the component can be split at the fracture zone, substantially without any ductile deformation, to separate a cap portion from the rest of the component to allow a separate component to be introduced into the aperture, whereupon the cap portion can be reunited with the rest of the component to close the aperture around the separate component.

  • Patent number: 4854747
    Abstract: A ball bearing comprising a substantially circular inner race having a first center, a substantially circular outer race having a second center substantially surrounding the inner race. The outer race is made up of a base and a pair of radially inwardly extending flanges which are spaced apart axially from one another. The flanges extend further inwardly at or adjacent the top of the bearing than they do from the bottom of the bearing. Rollable balls are held by the races in the usual manner. The provision of the extended upper flange permits greater wear of the balls before the bearing fails. This increases the times between the need for bearing changes.

  • Patent number: 4854746
    Abstract: An improved bearing assembly which may only be assembled when its principle components are properly fitted together is disclosed herein. Generally, the bearing assembly includes a saddle member and a bearing cap, each of which includes a main bearing receiving, semi-circular recess for journaling the crankshaft of an internal combustion engine. The recess of the saddle member is flanked on either side by first and second alignment slots, and the recess of the bearing cap is flanked by first and second mounting shoulders which are asymmetrical in shape with respect to the axis of rotation of the semi-cylindrical recess, and which are insertable within the first and second alignment slots of the saddle member, respectively. However, dissymmetry between the first and second shoulders prohibit the first shoulder from being inserted into the second alignment slot in a manner to cause proper alignment of the semi-cylindrical recesses.

  • Patent number: 4815585
    Abstract: A sanitary hanger bearing assembly for use in food handling screw conveyors is disclosed. The hanger bearing assembly employs a cam construction and stepped lug arrangement which are of substantial benefit in allowing the unit to be easily disassembled for washdown or maintenance, while holding the parts firmly together when the assembly is in the operating position.

  • Patent number: 4765759
    Abstract: A method and apparatus for supporting a journal bearing includes a three-part support key. The top piece is a rectangular member having a male cylindrical surface formed to mate with a female cylindrical groove formed axially with respect to a rotor in the bearing shell, and a female cylindrical surface formed perpendicularly to the male cylindrical surface. A middle piece having a top surface adapted to conform with the female cylindrical surface of the top piece and a flat bottom surface which is mated with the top piece and inserted within a keyway formed in the bearing pedestal. Thereafter, a bottom piece in the form of a variable thickness shim is inserted between the flat bottom surface and the keyway to align the rotor.

  • Patent number: 4741631
    Abstract: A split bearing support receives a crankshaft bearing. When joined, the two bearing support parts form a hub with a frustoconical outer surface. The hub has a plurality of spaced-apart bolt holes extending axially therein. The bearing support is received by a housing which has a central opening surrounded by a frustoconical inner surface which mates with the outer surface of the bearing support hub. The bearing support and the housing are held together by a plurality of bracket segments which are attached to the side of the bearing support by bolts received in the bolt holes.

  • Patent number: 4729674
    Abstract: A bearing composed of an inner race, two outer races concentric therewith and spaced axially from each other to leave a gap between them. Sets of ball bearings are located between the inner race and each of the two outer races. The outer races are provided with shoulders projecting axially toward one another and the whole is secured by a band wrapped circumferentially around the shoulders. Preferably, the band is thinner than the outer races so that part of the gap remains. The band is somewhat longer than the circumference and the ends are turned radially outwardly and fastened together.In a particularly improved form of the device, frames are located in the gap and are releasably fastened to one another. The width of the gap is larger than the thickness of the frames, so that there is a certain amount of play in the bearing. This provides a self-aligning feature.

  • Patent number: 4652151
    Abstract: A bearing assembly has a mounting bracket with an annular cut-out for supporting a bushing cradle with outer walls of corresponding angular shape for supporting a correspondingly shaped half block bushing. A half block bushing is used to support a roller journaled thereon. The half block form of the bushing permits convenient disassembly of the bearing for replacement of parts, and has longer and more stable wear characteristics. The outer walls of the bushing cradle are preferably trapezoidal to prevent rotational movement of the bushing relative to the cradle and mounting bracket, and to permit easy removal of the bushing during replacement. A spring metal clip lock is used to retain the bushing and cradle in position relative to the mounting bracket by spring pressure.

  • Patent number: 4647229
    Abstract: Two spaced support members support a shaft horizontal in partial lower bearing journal surfaces. A retractable pin is positioned above the shaft at each support member to retain the shaft in the journal surfaces. A shelf at each journal surface in front of the pins provides for loading and unloading of the shaft. A flat locking surface fixed to rotate with the shaft and a mating engagable locking member prevent rotation of the shaft.
