Filed: 1946-08-19
Abstract: 617,221. Ball bearings. TARLTON, F. H. Aug. 19, 1946, No. 24682. [Class 12 (i)] In a ball bearing which permits axial as well as angular movement of a shaft in its housing, a control spring has its ends bearing against the housing and the shaft respectively, and is connected at such a point along its length to the ball-cage that, on axial relative movement of the shaft and housing, the cage partakes of only one half of said relative movement. By thus controlling the balls and cage, pure rolling movement of the balls for axial movement of the shaft is ensured. The construction is shown applied to the mounting of a changespeed gear control-lever. The lever 10 is secured on a shaft 11 which is mounted in a housing 12, for both axial and angular movement, by means of a ball-bearing comprising two sets of balls 14 spaced apart and retained in a cage 15. Two compression springs 16, 17 of equal strength abut one against each side of the cage 15 and have their other ends abutting against the housing at 18 and against a ferrule 19 on the shaft 11 respectively. When axial movement of the shaft occurs, the springs 16, 17 are compressed or released by the same amount, and the cage 15 moves axially a distance equal to half the relative movement of the shaft with respect to the housing. Preferably when the springs are in their least stressed position they have a light loading endwise of the shaft.
