Embodiment Construction

[0033] figure 1 A cage blank 10 for a freewheel is shown. The blank is obtained by molding a plastic material, such as PA 6.6, PA 4.6 or PEEK, which may or may not be filled with glass fibres. The blank assumes the form of an elongated strip extending in a longitudinal direction defined by an axis X10 which is horizontal and rectilinear when the blank lies flat on a flat horizontal surface S.

[0034] The blank 10 extends along an axis X10 between a first end 12 and a second end 14 opposite the first end 12 . The end portion 12 is provided with two struts 122 and 124 extending beyond a terminal transverse edge 126 of the end portion 12 along the axis X10 . End 14 defines two notches 142 and 144 for receiving and retaining struts 122 and 124 in the closed configuration of blank 10, which configuration will be described below. Each of the notches 142 and 144 is arranged on a protrusion 146 protruding beyond a transverse terminal edge 148 of the end portion 14, which edge is a...

Abstract

A cage blank for a free wheel with rolling bodies is formed by an elongated strip defining housings for receiving rolling bodies juxtaposed in a rectilinear longitudinal direction of the blank. It is provided, at both of its ends, with means for attaching the two ends together, in a configuration where the cage forms a closed loop. A cage is formed by bending the blank on itself, perpendicular to its longitudinal direction, and engaging its attaching means.

Description

technical field [0001] The invention relates to a cage blank for a freewheel with rolling elements. Such blanks are used in the manufacture of freewheels with rolling elements to make cages that hold the rolling elements in place during use of the freewheel. The invention also relates to a freewheel cage formed from such a blank and to a freewheel comprising such a cage. Finally, the invention also relates to a method of assembling such a freewheel. Background technique [0002] In the field of freewheels, it is known to retain the rolling elements of a freewheel, such as rollers or balls, between the inner and outer rings of the freewheel by using rings that define a housing for receiving and guiding the rolling elements. proper location. Such loops may be formed from folded cut metal strips or from loops of molded synthetic material. [0003] With this type of cage, the rolling elements have to be successively introduced into the cells of the cage from inside it, which...
