Abstract:
An idler roll assembly having an outer shell and end bearing produced by the steps of:a) providing a hollow cylindrical outer shell and a pair of end bearing assemblies said end bearing assemblies each comprising a bearing having an inner and outer race and tapered rollers therebetween, with said outer race affixed to an end cap and an inner race adapted to be inference fit on an end of a roller shaft; b) providing a roller shaft having an outside diameter slightly larger than an inside diameter of said inner race, said shaft having means for engaging an reciprocally moving said shaft relative to said outer shell for determining degree of axial movement; c) interference fitting the inner race of each bearing assembly on said shaft at opposite ends thereof to an initial position which is spaced axially outwardly from a final desired position, such that the inner race is movable relative to said shaft during inner race location adjustment to the final position and remains stationary relative to the shaft subsequent to adjustment; d) fitting each end cap within the ends of the outer shell; e) welding each end cap to said outer shell; f) restraining said outer shell and reciprocating said shaft along its longitudinal axis and relative to said shell to determine the degree of axial movement and, therefore, bearing clearance; and g) moving said inner race of said bearing assembly from its initial position to its final position as determined by said degree of axial movement, said inner race having means receiving an adjustment force from the adjustment machine to move said inner race to its final position, such that the inner race is at the final position that is determined via reciprocation of said shaft engaging means by the adjustment machine.
