Abstract

Rollers in sections with quick clutch mechanism are retained by means of balls situated in grooves in the roller or in its shaft extension. The grooves are formed by symmetric cone-shaped facing surfaces between which an additional surface parallel with the axis may be provided. The angle of opening of the cone-surface is >=90 degrees and the distance of the section lines of the cone-surfaces with the mantle-surface of the shaft is at least 1.5 times that of the groove diameter when they are in the grooves.
