A method is described for producing a body belonging to a friction pairing, for example a synchronizing ring (1) or an intermediate ring, for a synchronized manual gearbox or variable-speed gearbox, with a frictional surface (2) which serves to interact with a mating body and is formed from the sum of the contact surfaces (8) of a multiplicity of frictional bodies (3) which are separated from one another by grooves (4) running at an angle to the designated rotational movement of the body (1), said contact surfaces acting on the mating body in order to bring about synchronism therewith. In this case, it is provided that, in a first step, a body (14) is provided with frictional bodies (3) premanufactured close to the final shape, and, in a following step, the frictional surface (2) formed by the sum of the contact surfaces (8) of the frictional bodies (3) is adjusted during the course of a processing step in which material is removed from the frictional bodies (3) premanufactured close to the final shape. A body belonging to a frictional pairing, for example a synchronizing ring (1) or an intermediate ring, for a synchronized manual gearbox or variable-speed gearbox has a frictional surface (2) which serves to interact with a mating body and is formed from the sum of the contact surfaces (8) of a multiplicity of frictional bodies (3) which are separated from one another by grooves (4) running at an angle to the designated rotational movement of the body (1), which contact surfaces act on the mating body in order to bring about synchronism therewith. The contact surfaces (8) of the frictional bodies (3) are adjacent at their ends bounded by grooves (4) to the adjacent groove wall (6, 7') with a respective edge (12, 13) being formed with a maximum radius of 0.2 mm. Groove walls (6, 7') bounding the contact surface (8) of a frictional body (3) run parallel or virtually parallel to each other. |
