Abstract

Abstract A differential gearing mechanism including pinion gears supported in a housing by a pinion support member. The support member comprises a central member having an axial opening and a pair of bores disposed on axes angularly related to the axial opening. The central opening receives a pin which also extends through coaxial openings in the housing and supports a pair of pinion gears. The support member further includes a pair of support elements respectively extending through further housing openings and each element has one end secured in a bore and the opposite end supported in an associated housing opening. The differential gear mechanism is assembled by locating the pinions in the housing and aligning support pinion openings with respective housing openings, inserting the pin through coaxial housing openings and the central opening, and inserting the respective support elements through the remaining housing openings and securing the one end of the elements in the support member bore. In a modified form, the central member includes a plurality of bores angularly related to each other and each receiving a pinion support element.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 142 words
A pinion supporting member for supporting at least four pinion gears in a housing comprising a central member having an axial opening extending therethrough, said central member having two opposed surfaces extending parallel to said axis, said member further having threaded bores extending from each surface and angularly related to said axis; a pin having a central portion disposed in said opening and oPposite ends extending beyond said member; and a pair of support elements, said support elements each comprising a bolt having one threaded end and an enlarged head on said opposite end, said threaded ends received in respective ones of said threaded bores; said support elements further including sleeves each having one end received in one of said bores and adapted to rotatably support a pinion gear, said opposite ends of said pin each adapted to support a pinion gear.
Claim 2
Dependent Claim 142 words
A pinion supporting member for supporting at least four pinion gears in a housing comprising a central member having an axial opening extending therethrough, said central member having two opposed surfaces extending parallel to said axis, said member further having threaded bores extending from each surface and angularly related to said axis; a pin having a central portion disposed in said opening and oPposite ends extending beyond said member; and a pair of support elements, said support elements each comprising a bolt having one threaded end and an enlarged head on said opposite end, said threaded ends received in respective ones of said threaded bores; said support elements further including sleeves each having one end received in one of said bores and adapted to rotatably support a pinion gear, said opposite ends of said pin each adapted to support a pinion gear.
Claim 3
Dependent Claim 189 words
In combination with a differential gear housing and a plurality of pinion gears, pinion gear supporting mechanism comprising a central member having an axial opening extending therethrough, said member having a plurality of bores disposed on axes angularly related to said opening; means defining a pair of openings in said housing, said pair of openings having a common axis aligned with said axial opening; means defining further openings equal in number to the number of bores and each of said further openings being aligned with respective ones of said bores; a pin received in said pair of housing openings and said member opening, said pin supporting a pair of said pinion gears respectively disposed between said central member and respective ones of said housing openings; and a plurality of support elements equal in number to the number of said bores, each said support elements including a sleeve having an intermediate portion supporting a pinion gear and having an end portion received in a bore, each said support elements having an opposite end received in respective ones of said further openings, and threaded means maintaining said sleeves in said bores.
Claim 4
Dependent Claim 189 words
In combination with a differential gear housing and a plurality of pinion gears, pinion gear supporting mechanism comprising a central member having an axial opening extending therethrough, said member having a plurality of bores disposed on axes angularly related to said opening; means defining a pair of openings in said housing, said pair of openings having a common axis aligned with said axial opening; means defining further openings equal in number to the number of bores and each of said further openings being aligned with respective ones of said bores; a pin received in said pair of housing openings and said member opening, said pin supporting a pair of said pinion gears respectively disposed between said central member and respective ones of said housing openings; and a plurality of support elements equal in number to the number of said bores, each said support elements including a sleeve having an intermediate portion supporting a pinion gear and having an end portion received in a bore, each said support elements having an opposite end received in respective ones of said further openings, and threaded means maintaining said sleeves in said bores.
Claim 5
Dependent Claim 30 words
The combination as defined in claim 2, in which there are two threaded bores disposed on a common axis which extends substantially perpendicular to the axis of said member opening.
Claim 6
Dependent Claim 23 words
The combination as defined in claim 2, in which said member opening has a diameter slightly greater than the diameter of said pin.
Claim 7
Dependent Claim 179 words
In combination with a differential gear housing and at least three pinion gears, pinion gear supporting mechanism comprising a central member, said member having a plurality of angularly related surfaces equal in number to said pinions, said member further having a plurality of threaded bores equal in number to said pinion gears and located in respective ones of said surfaces; means defining a plurality of openings in said housing equal in number to said pinion gears with each opening axially aligned with respective ones of said bores; a pinion support element for each of said bores; said pinion support elements each including a sleeve having one end received in respective ones of said bores and having an opposite end supported in the aligned opening, said support elements each being configured to be received through a housing opening whereby said support elements may be inserted through said housing openings and support openings in said pinion gears and threaded into said bores; and threaded means extending through said sleeves and received in said bores for securing said sleeves to said members.
Claim 8
