Abstract

1,225,786. Needle bearings. NADELLA, and A. PITNER. 13 June, 1968 [21 June, 1967], No. 28060/68. Heading F2A. A needle roller bearing is assembled by sliding needles 1 into a cylindrical bone 9, provided at one end with an annular ring 13, from a sleeve 2 in which they are retained axially by an annular ring 3 at one end and retained radially in the sleeve by an elastic disc 8. Inwardly folded tabs 6 may be provided at the other end of the sleeve. The needles are inserted in the bore by applying axial pressure to the ring 3 by a suitable tool 16 which has a shoulder 17 abutting the ring 3. The needles are forced past the tabs 6 and into the bore until they abut the ring 13. The tool 16 is then removed and the shaft 18 (Fig. 2, not shown) which is to be journalled by the needles inserted thereby expelling the disc 8. The tabs 6 retaining the needles axially may be dispensed with if the disc 8 provides sufficient radial force that the needles are retained in the sleeve 2 by frictional forces. Alternatively, the disc 8 may be omitted and the needles held in the sleeve by an adhesive applied to the inner surface of the sleeve which is subsequently dissolved in lubricant.
