Connecting rod bearing housing
View Patent ↗A connecting rod bearing housing includes an attaching portion and a retaining portion releasably joined together. The attaching portion and the retaining portion are each provided with a pair of alignment bores respectively located on opposite sides of the transverse passageway. The alignment bores are registered with one another and partially intersect the transverse passageway. An alignment washer is held within each pair of registered, alignment bores and projects into the transverse passageway. A sleeve-like bearing is positioned within the transverse passageway and has notches for snugly receiving the alignment washers. The washers prevent the rotation of the bearing within the housing.
1. A connecting rod bearing housing, comprising:
an attaching portion including:
a top plate with opposite sides; and,
a pair of first arms, each being affixed to a respective one of said opposite sides of said top plate and extending downwardly from said top plate wherein said top plate and said first arms define a first cylindrical concavity in the bottom of said attaching portion, and the bottom of each of said first arms are provided with an upwardly extending alignment bore, each said upwardly extending alignment bore having a first upper part that is helically threaded and a first lower part having a diameter that is greater than that of said first upper part, and said first lower part intersecting said first cylindrical concavity;
a retaining portion being releasably fastened to said attaching portion, said retaining portion including a pair of second arms being affixed to one another, said second arms extending upwardly and outwardly from one another, and said second arms defining a second cylindrical concavity in the top of said retaining portion, and the top of each of said second arms being provided with a downwardly extending alignment bore positioned for registration with a respective one said upwardly extending alignment bore in said attaching portion, each said downwardly extending alignment bore having a second lower part and a second upper part having a diameter that is greater than that of said second lower part, and said second upper part intersecting said second cylindrical concavity;
a pair of alignment washers, each of said alignment washers being snugly, yet releasably positioned in said first lower part of a respective one of said upwardly extending alignment bores and said second upper part of a respective one of said downwardly extending alignment bores; and,
a pair of first threaded fasteners, each of said first threaded fasteners having a threaded shaft passing through one said alignment washer and being screwed into said first upper part of a respective one of said upwardly extending alignment bores, and each of said first threaded fasteners also having an enlarged head being affixed to said threaded shaft and positioned in said second lower part of a respective one of said downwardly extending alignment bores.
2. The connecting rod bearing housing according to claim 1 further comprising an alignment plug being affixed to said top plate and extending upwardly therefrom for insertion into a connecting rod.
3. The connecting rod bearing housing according to claim 2 further comprising a pair of alignment pins being affixed to said alignment plug and extending upwardly therefrom for insertion into a connecting rod so as to prevent misalignment between said connecting rod bearing housing relative to the connecting rod.
4. The connecting rod bearing housing according to claim 3 wherein each of said alignment pins includes:
a disk with a central opening;
a cylindrical, side wall being affixed to, and extending upwardly from, the periphery of said disk; and,
a second threaded fastener for affixing said disk to said alignment plug.
5. The connecting rod bearing housing according to claim 4 wherein said alignment plug is provided with a pair of downwardly extending alignment apertures into each of which said disk of one of said alignment pins is fitted and said second threaded fastener is screwed.
