Definitions
- the invention relates to a brush holder for
- an auxiliary assembly ring is used which, in the completed brush holder, the spring-loaded commutator brushes in the
- Brush holder holds back. This assembly ring is removed when joining the brush holder with the commutator or collector in the commutator machine and transported back to the assembly station.
- a supply connection for the commutator brush has one in a known brush holder of the type mentioned at the beginning (EP 0 741 438 B1)
- Holding section on the inserted in the brush holder Commutator brush and brush pressure spring overlaps the face of the commutator brush remote from the brush pressure spring, thereby preventing the spring-loaded commutator brush from escaping from the brush holder.
- this holding section is bent outwards in each of the brush holders held on the brush pressure plate, so that it releases the commutator brush and the commutator brushes are pressed onto the commutator bars of the commutator by the brush pressure springs.
- the brush holder according to the invention has the advantage that, by using the lateral guide play of the commutator brush in the brush holder, the retaining member is realized by a simple machining measure on the brush holder itself, and thus a positive connection between the commutator brush and the brush cook can be produced.
- This positive locking which is achieved without inserting an additional component in the brush holder, holds the pretensioned commutator brush reliably in the brush holder during the entire assembly.
- the release of the positive connection after installing the brush holder in the commutator machine can then be easily accomplished in various ways.
- the retaining member can be constructed in a very simple manner in that, on the one hand, the guide play between the brush holder and commutator brush is dimensioned such that the commutator brush can assume an inclined position in the brush holder, in which the brush axis forms a small acute angle with the - holder axis includes, and that, on the other hand, a locking shoulder cooperating with the commutator brush in its inclined position is formed on one of the quiver walls of the brush holder.
- the locking shoulder extends near the brush exit edge of the brush holder over the entire wall width of the holder wall, and the inclined commutator brush is supported on the locking shoulder with its end face facing away from the brush pressure spring.
- the latching shoulder is formed by the lower edge of a recess that completely penetrates the quiver wall or by the lower flank of a groove-like depression made on the inside of the quiver wall.
- Front side of the commutator brush or on the side surface of the commutator brush whereby to achieve an inclined position the push-in force for pushing the commutator brush into the brush holder against the force of the brush pressure spring is offset off-center, specifically towards the holder wall carrying the locking shoulder, on the free end face of the Commutator brush attacks.
- the action of force on the side surface of the commutator brushes takes place from the outside through the wall of the quiver, for which purpose corresponding
- the locking shoulder is arranged in the quiver wall so that when the front side of the commutator brush rests on the locking shoulder, part of the front side protrudes beyond the brush exit edge of the brush holder to such an extent that when the brush holder is joined to the commutator, the latter touches the front side of the Commutator brush abuts. If the commutator is now advanced further, the brush is pressed slightly inwards by the commutator, whereby it is pushed through the
- Commutator lamella is pivoted back so that its brush axis is aligned almost parallel to the quiver axis and the end face of the commutator brushes is pulled off the locking shoulder.
- the positive engagement between the commutator brushes and the individual brush holders is advantageously canceled automatically by inserting the commutator, and additional assembly processes or auxiliary tools for applying a transverse force to the commutator brush can be saved.
- FIG. 1 is a partial perspective view of a commutator of a commutator machine with a built-in brush holder
- Fig. 2 shows a section along the line II - II in
- Fig. 3 each have a longitudinal section of one and 4 brush holder of the brush holder in Fig. 1 and 2 with commutator brush and
- FIG. 5 each shows a longitudinal section of a modified to 7 brush holder according to three further exemplary embodiments.
- the brush holder 10 to be seen in detail in FIG. 1 and in section in FIG. 2 for a commutator machine, for example for a direct current motor, has a brush plate 11 on which at least two radially aligned brush holders are offset by the same circumferential angle 12 are attached.
- Each brush holder 12 is shaped like a box with a rectangular cross section and is closed at one end with a holder bottom 121.
- a locking cam 126 is formed, with which the brush holder 12 in a locking recess 19 in the Brush plate 11 is inserted and locked therein.
- Another lateral quiver wall 122 is provided with a longitudinal slot 13 (FIG.
- a commutator 15 is inserted, which is axially displaceably guided with a relatively large clearance in the brush holder 12 •.
- a brush pressure spring 16 which is supported between the quiver bottom 121 and the end face 151 thereof facing the commutator brush 15, presses the commutator brush 15 onto the commutator bars 17 of a commutator 18 of the commutator machine after the brush holder 10 has been installed.
- the brush holder 10 is non-rotatably fixed in the commutator machine via the brush plate 11.
- the brush holder 10 In the manufacture of the commutator machine, the brush holder 10 is preassembled as a complete unit and inserted into the commutator machine, the pre-assembly station of the brush holder often being spatially separated from the final assembly station of the commutator machine in the case of automatic production, and the completed brush holder 10 with pretensioned brush pressure springs 16 must travel even longer distances.
- a retaining member 20 is integrated in each brush holder 12 and blocks the spring-loaded commutator brush 15 from being pushed out of the brush holder 12. This retaining member 20 is activated during the assembly of the brush holder 10 and until the brush holder 10 is installed in the commutator machine kept activated and deactivated again at the end of assembly, that is to say after fixing the brush holder 10 in the commutator machine and installing the commutator 18.
- the play between the brush holder 12 and commutator brush 15 is used, which is sufficient for the commutator brush 15 to be able to assume an inclined position in which the brush axis forms a small acute angle with the holder axis (cf. 3 and 4), and on the other hand, in a quiver wall 123 near the brush exit edge 125 of the brush holder 12, a locking shoulder 21 is provided which produces a positive connection by slightly tilting the commutator brush 15 with the commutator brush 15 in its inclined position.
- the locking shoulder 21 extends over the entire width of the quiver wall 123, so that the inclined commutator brush 15 with its end face 152 facing away from the brush pressure spring 16 can rest on the locking shoulder 21.
- the locking shoulder 21 is in the embodiment of FIGS. 1-4 from the lower edge of the brush exit edge 125 facing the lower edge of a recess 22 which completely penetrates the quiver wall 123 and in the embodiment of FIGS. 5 and 6 from the lower edge facing the brush exit edge 125 Groove flank of a groove-shaped depression 23 or 23 'running on the inside of the quiver wall 123 is formed. In the latter case, a through hole 24 (FIG. 5) or a slot 28 (FIG. 6) which ends freely at the brush exit edge 125 of the brush holder 12 (FIG. 6) is made in the wall of the holder
- Recess 23 or 23 ' opens.
- a through hole 25 running near the recess 23 can also be provided, which is shown in broken lines in FIG. 5.
- the depression 23 ' is guided and pierced through to the bottom of the holder 121 to remove the brush holder 12 from the injection mold. (Figs. 6 and 7)
- FIGS. 3 and 4 Two steps of the assembly process of the brush holder 10 are shown schematically in FIGS. 3 and 4.
- the commutator brush 15 is pushed into the brush holder 12 while the brush pressure spring 16 is being tensioned.
- the insertion force which is symbolized in FIG. 3 by arrow 26, is set off-center on the free end face 152 of the commutator brush 15, specifically towards the quiver wall 123 carrying the latching shoulder 21.
- the commutator brush 15 assumes an inclined position within the brush holder 12 shown in FIGS. 3 and 4, and at the end of the insertion process, the end face 152 of the commutator brush 15 lies on the latching shoulder 21.
- FIG. 7 of a brush holder 12 shown in longitudinal section with commutator brush 15 is modified to the extent that
- the retaining member 20 is in turn designed as a locking shoulder 21, which on the quiver wall 124
- Brush exit edge 125 of the brush holder 12 is arranged and is formed by the lower groove flank of the groove-like depression 23 ′ facing the brush exit edge 125.
- the commutator brush 15 By pushing the commutator brush 15 into the brush holder 12 by means of an eccentrically acting insertion force which counteracts the brush pressure spring 16, the commutator brush becomes 15 is in turn fixed with its free end face 152 on the locking shoulder 21.
- the arrangement and design of the locking shoulder 21 is such that a part of the side surface of the end face 152 of the commutator brush 15 projects beyond the brush exit edge 125 of the brush holder 12 to such an extent that it projects into the insertion area of the commutator 18. If, after the brush holder 10 has been fastened in the commutator machine, the commutator 18 is pushed in in the direction of arrow 27 in FIG. 7, the front edge of the commutator 18 abuts the end face 152 of the
- Commutator brush 15 and pushes it into the brush holder 12, causing the commutator brush 15 to stand up and its end face 152 to slide off the locking shoulder 21.
- the commutator brush 15 is now pressed onto the commutator bar 17 of the commutator 18 by the brush pressure spring 16.
