Method of making a hooks joint

摘要

A Hooke's joint comprises four bearing cups received in openings in respective yoke arms and retained therein by respective retaining elements. At least one retaining element associated with each yoke has radially-projecting fingers which terminate in cutting edges and which are seated in a groove cut in the wall of the corresponding opening by rotation of the retaining element. There is also described a tool for contracting the retaining element to enable it to be inserted into the opening and for rotating the retaining element.
