ABSTRACT:
A telescopic drive line includes an inner square drive shaft and an outer drive tube having a square bore at one end. A thin-walled liner in the bore has an inner surface providing a low-friction axial bearing for the drive shaft. The considerably greater coefficient of friction between the outer body of the liner and the bore of the drive tube secures the liner axially in the bore irrespective of the radial force applied to the liner. Only supplementary securement is provided by a key fitted in a keyway. The several liners fit between inward projections of the key. An outward projection fitting a recess in the drive tube secures the key axially. Deflection of the exposed end of the key allows the projecting tab to be disengaged from the recess for insertion and withdrawal of the key along with the several sleeves.
