Spacer for a Driveshaft Assembly
First Claim
1. A driveshaft assembly comprising:
- (a) a tubular shaft comprising;
(i) at least a first receiving end portion with an opening disposed therein, wherein the receiving end portion has a receiving end portion inner diameter,(ii) a center portion, wherein the center portion has a center portion inner diameter, and(iii) a hollow interior with a shaft inner surface,(b) a driveshaft end component comprising an insert end portion and an attachment end portion; and
(c) an annular anti-fretting spacer comprising;
(i) a first outer diameter, wherein the first outer diameter of the spacer is substantially equal to the receiving end portion inner diameter(ii) a second outer diameter, and(iii) an outer surface, wherein at least a portion of the outer surface is in contact with the shaft inner surface,wherein the spacer is disposed on the insert end portion of the driveshaft end component, wherein the insert end portion of the driveshaft end component, including the spacer, is disposed within the receiving end portion of the shaft with an interference fit, and wherein the shaft is rigidly coupled to the driveshaft end component.

Abstract
A driveshaft assembly having a tubular shaft, an end component, and an annular anti-fretting spacer is disclosed. The tubular shaft has a first receiving end portion with an opening and an inner diameter, a center portion with an inner diameter, and an interior with an inner surface. The driveshaft end component has an insert end portion and an attachment end portion. The spacer has a first outer diameter that is substantially equal to the receiving end portion inner diameter, a second outer diameter, and an outer surface. At least a portion of the outer surface contacts the shaft inner surface and the spacer is disposed on the insert end portion of the driveshaft end component and the insert end portion, including the spacer, is disposed within the receiving end portion with an interference fit, and the shaft is rigidly coupled to the driveshaft end component.
