Abstract

117,878. Keith, J., and Keith, G. Nov. 30, 1917. Friction gearing.-Relates to hand-power speedmultiplying gear for driving fans &c. It comprises an outer race B and a fan &c. spindle A, between which are interposed pairs of frictionrollers C, D, some of which are mounted on eccentric bushes and are automatically jammed into engagement with a force increasing with the load. In the form shown in Fig. 1, the race B is rotated by hand, and the rollers C, D, which are on relatively fixed axes d, f are pressed between A and B by a spring k acting through links g on the rollers D and the rollers C are mounted on eccentric bushes e to cause them to jam. In a modification, a spring device similar to k is arranged within the race B. Annular grooves may be formed inside the race B to facilitate the squeezing out of the oil film from between the rollers and the race, and this race may be provided with side-flanges.
