Abstract
A machine for rolling the outer races of bearings in an external die with the assistance of a rolling tool roller operating in overhanging relationship in a race blank to be rolled, and the roller is mounted to the end of an eccentric spindle fitted in a sleeve mounted in turn eccentrically in another sleeve, wherein the two sleeves are rotatably driven, the spindle and tool roller being rigidly assembled and rotatably driven from a motor at such speed that the apparent speed of the tool roller approaching the blank to be rolled is substantially zero, the sleeves being driven through an epicyclic gear train connected through two of its rotating members to the sleeves, these two members coacting with a third member of the gear train which consists of a reaction member responsive to a member controlling the relative angular displacement of the sleeves.
