Abstract
An interlocking thrust washer is presented. The thrust washer including a first annular upper ring having first inner and outer side circumferential surfaces and first top and bottom surfaces. The upper ring providing at least two holes that extend therethrough the first top and bottom surfaces and a first annular lower ring having second inner and outer side surfaces and second top and bottom surfaces. The first lower annular ring includes at least two annular projections extending upward from the second top surface. The at least two annular projections align with the at least two holes to create an interlocking fit between the first annular upper and lower rings. The interlocking fit allows the first upper and lower rings to combine and function as the single element thrust washer 10 once interlocked together. The interlocking fit further prevents any rotation between the first upper and lower annular rings during operation.
