2. Description of the Related Art A so-called cylindrical commutator (Rollkommutato)
It is known to produce commutator rings for r) from pre-embossed strip material. In this case, a groove is formed in a possibly shaped endless strip with a width corresponding to the axial length of the commutator using a forming tool in a direction perpendicular to the direction of movement of the strip. , Which now results in commutator strips which are only connected via the web. Depending on the number of commutator strips of the commutator ring, a corresponding number of commutator strips are separated from the now shaped continuous strip and rolled into a commutator ring. In order to shape-stabilize the commutator ring and to insulate the individual commutator pieces from each other, the commutator ring is often embedded in an insulating material together with a metal boss.

According to the present invention, it is possible to securely fix the commutator piece to the insulator while maintaining the available commutator piece thickness or strength. By the fixing means being configured as an interrupted dovetail-shaped molding extending in the axial direction of the commutator piece, the desired shape of the commutator piece can be obtained using only one method step which can be carried out easily.

The commutator ring is shown in FIG. 3 in a partially enlarged view. The legs 16 which serve as connecting contacts are not shown in FIG. 3, since in the following reference will be made to the production of the fastening means 18 according to the invention. As is clear from what is shown in FIG.
It is configured integrally with the second leg 14. The fixing means 18 has a dovetail-shaped molding portion 22 that extends inward in the radial direction when viewed in cross section. As is apparent from the enlarged view shown in FIG. 3, the individual commutator strips 12 are spaced from one another and do not have direct contact contacts. Since the intermediate chamber 20 is filled with the insulating material of the insulator 11, the commutator pieces 12 are electrically insulated from each other. At the same time for this insulating material, the fixing means 1
8, that is, the dovetail shaped portion 22 is engaged. In this case, the dovetail shaped portion 22 is configured so as to be interrupted in the longitudinal direction of the commutator piece 12, that is, in the axial direction of the commutator ring 10. The interrupted dovetail-shaped parts 22 are, in the longitudinal direction of the commutator piece 12, alternating sections 24 with dovetail-shaped parts 22 and sections 26 without dovetail-shaped parts. ,That's what it means. The number of sections 24; 26 across the length of the commutator strip 12 is selectable. For example, according to the first embodiment, there is one section 24 and one section for each commutator piece.
According to another embodiment, a relatively large number of sections 24; 26 are provided alternately. In the embodiment shown in FIG. 5, the commutator piece 12
One section 24 with a dovetail-shaped molding 22 is formed in each of the end regions of the legs 14 of the, whereas the intermediate portion located between the two end sections has a dovetail-shaped molding. It forms a section 26 without a section.

The commutator 12 is usually embossed from a molding strip 30 made of copper. For this purpose, in a first method step, a notch 32 is produced with a forming tool in the direction perpendicular to the longitudinal direction of the forming strip 30 over the forming strip 30. The material 34 of the commutator element 12 is produced by the notches 32 provided at intervals from each other. These materials 34 are simply joined together via a web 36. The configuration of the forming tool for producing the cutout 32 causes the blank 34 to have a trapezoidal shape in cross section, so that the side surfaces 38 extend at a selectable angle relative to one another.

By the manufacturing method according to the present invention as a whole, the commutator ring 10, particularly the commutator piece 12 of the commutator ring 10, and the cross section of the commutator piece 12 are not damaged by the structure of the fixing means 18. As such, it is possible to manufacture. The integral embossing of the dovetail molding 22 simply pushes the material away, which does not result in an overall thinner or weaker cross section. At the same time, the following are achieved using easily implementable manufacturing steps. That is, in this case,
It is possible to configure the fixing means 18 which at the same time guarantee a reliable fixation both in the radial and axial directions of the commutator element. Furthermore, the alternating sections 24; 26 of the commutator strip 12 ensure the strength of the commutator strip 12, that is to say the strength that ensures bending or winding of the commutator ring 10.
