Below, Fig. 8 A, Fig. 8 B and the manufacture method of Fig. 8 C to the brush dish assembly 1 in the second exemplary execution mode of the present invention is utilized to be described.Fig. 8 A and Fig. 8 B is the amplification plan view that the brush peripheral structure before temporarily fixing is shown.Fig. 8 C is the amplification plan view that the brush peripheral structure after temporarily fixing is shown.The difference of Fig. 8 A and Fig. 8 B is, the position of the brush 3 contacted with the contact site 721 of pressure-producing part 7 is different.
First, pressure-producing part 7 is held in brush dish 2.That is, by the contact site 721 of pressure-producing part 7 towards radially inner side, and by the circular maintaining part 241 of maintaining part 24 and the main part 73 of pressure-producing part 7 at axial overlap, in this condition, main part 73 is embedded into circular maintaining part 241 from axial upside.
At this, brush 3 is configured in the periphery in the hole 21 of brush dish 2.As shown in Figure 8 A, in the guide part 22 of brush dish 2, brush 3 is moved to radial outside with the state of its other end 32 towards radial outside.First groove 321 of brush 3 is contacted with the contact site 721 of pressure-producing part 7.In addition, in this case, from pressure-producing part 7 pairs of brushes 3 to the direction force shown in the blank arrowhead of Fig. 8 A.
Then, brush 3 is made to move to radial outside further from the state shown in Fig. 8 A.Fig. 8 B illustrates first groove 321 of the contact site 721 of pressure-producing part 7 with brush 3 and the state of the second groove 331 continuous print location contacts.
In this case, from pressure-producing part 7 pairs of brushes 3 to the direction force shown in the blank arrowhead of Fig. 8 B.Now, brush 3 is likely to peripheral, oblique.
But as shown in Figure 8 B, the peripheral side of brush 3 side of the protuberance 231A of fixed part 23A extends from the radial position that the radial position of the other end 32 with brush 3 is roughly the same to radial outside.Therefore, by the peripheral side of described protuberance 231A, brush 3 can be suppressed to peripheral, oblique.That is, the possibility that brush 3 breaks can be reduced.
Finally, brush 3 is temporarily fixed on brush dish 2.Fig. 8 C illustrates the state after temporarily fixing.Brush 3 is moved to radial outside further from the state shown in Fig. 8 B.The contact site 721 of pressure-producing part 7 is connected with the second groove 331 of brush 3.In this condition, from pressure-producing part 7 pairs of brushes 3 to the direction force shown in the blank arrowhead of Fig. 8 C.This state is the state that brush 3 is temporarily fixed on brush dish 2.In addition, identical with Fig. 8 B, in Fig. 8 C, also brush 3 can be suppressed to peripheral, oblique by the peripheral side of protuberance 231A.That is, the possibility that brush 3 breaks can be reduced.
Then, the operation of the state removing temporary transient fixed brush 3 is described.
First, under the state of the hole 21 of axle 102 and brush dish 2 at axial overlap, axle 102 is inserted into the assigned position that the axial height of commutator 103 and brush 3 is consistent.Then, the other end 32 of brush 3 is exerted a force from radial outside to radially inner side.
Thus, with from Fig. 8 C to Fig. 8 B, order from Fig. 8 B to Fig. 8 A, brush 3 is removed by the state of temporarily fixing.One end face 31 of brush 3 contacts with commutator 103, and the first groove 321 of the other end 32 of brush 3 contacts with the contact site 721 of pressure-producing part 7 simultaneously.
So, due to without the need to arranging miscellaneous part in order to temporary transient fixed brush 3, therefore, it is possible to reduction arranges the flow chart of this miscellaneous part, thus operating efficiency is improved.Further, when removing the state of temporary transient fixed brush 3, commutator 103 and shifting brush 3 is not moved.That is, owing to not being that commutator 103 and brush 3 both sides move, therefore, it is possible to reduce brush 3 to produce the possibility of breaking.
Above, the first exemplary execution mode of the present invention and the second execution mode are illustrated, but structure of the present invention is not limited to above-mentioned example.Such as, each key element occurred in each execution mode and its variation also can suitably combine in the scope not producing contradiction.
In addition, the present invention such as can be used in anti-locking braking device motor.
