Abstract
A torque assembly including a housing including a first piece, a bore, a first coupling attachment; a second piece including a second coupling attachment; a pin including a flange and a pin protrusion, where the pin protrusion protrudes through the bore of the first piece; a first washer including a compound layer adapted to contact the pin and the first piece of the housing to modify torque between the first piece and the pin; and a second washer including a compound layer adapted to contact the pin and the second piece of the housing to modify torque between the second piece and the pin.
Claims20
A torque assembly comprising:
- a housing comprising a first piece comprising a first face, a first circumferential flange projecting axially from the first face, and a bore, and a second piece comprising a second face comprising an integral housing connector;
- a pin comprising a flange and a pin protrusion extending therefrom, the pin protrusion protruding through the bore of the first piece;
- a first washer comprising a compound layer thereon adapted to contact the pin and the first piece of the housing to modify torque between the first piece and the pin;
- and
- a second washer comprising a compound layer thereon adapted to contact the pin and the second piece of the housing to modify torque between the second piece and the pin, wherein at least one of the first washer or second washer is frictionally coupled to the pin.
A torque assembly comprising:
- a housing comprising a first piece having a central axis comprising a axial first end comprising a first face, a bore, and a axial second end comprising a flange projecting around a circumference of the first face, and a second piece comprising a axial first end comprising a first face, and a axial second end comprising a flange projecting around a circumference of the first face;
- a pin comprising a axial first end comprising a first face and an axial second end comprising a pin protrusion protruding from the first face through the bore of the first piece;
- a first washer comprising a compound layer thereon adapted to contact the pin and the first piece of the housing to modify torque between the first piece and the pin;
- and
- a second washer comprising a compound layer thereon adapted to contact the pin and the second piece of the housing to modify torque between the second piece and the pin, wherein the torque assembly is substantially free of lubricant, wherein the second piece of the housing further comprises a second face comprising an integral housing connector, wherein at least one of the first washer or second washer is frictionally coupled to the pin.
A method comprising:
- providing a torque assembly comprising:
- a housing comprising a first piece comprising first face, a first circumferential flange projecting axially from the first face, and a bore, and a second piece comprising a second face comprising an integral housing connector;
- a pin comprising a flange and a pin protrusion;
- a first washer comprising a compound layer thereon adapted to contact the pin and the first piece of the housing to modify torque between the first piece and the pin;
- and
- a second washer comprising a compound layer thereon adapted to contact the pin and the second piece of the housing to modify torque between the second piece and the pin;
- contacting the first washer with the first face of the first piece of the housing;
- contacting the second washer with the first face of the second piece of the housing;
- contacting the first piece of the housing with the second piece of the housing to at least partially surround the pin such that the pin contacts the first washer and the second washer, and the pin protrusion protrudes through the bore of the first face of the first piece;
- and
- rotating the assembly wherein at least one of the first washer or the second washer provides modification of torque based on the compound layer on at least one of the first washer or the second washer, wherein at least one of the first washer or second washer is frictionally coupled to the pin.
