Abstract
A mechanically commutated electric motor, having a brush holder which comprises guide rails (17, 18) for longitudinally guiding engagement into corresponding guide grooves (19, 20) in a brush (11). The arrangement of the brush holder (10) is effected in such a way that a location opening (14) for the brush (11) formed by the guide rails (17, 18) lies substantially in a plane defined by a motor axis (22) and a perpendicular (37) to said motor axis (22).
Description
The present invention relates to a kind of mechanical commutation motor that has a brush clamp, this brush clamp has corresponding pairs ground roughly along the guide rail that becomes direction extends parallel radially with motor axis, corresponding two guide rails form the ccontaining opening of brush betwixt and are designed in order to longitudinally to engage with the respective guide slots of brush, brush is in becomes the position that radially is provided with the rotation of motor.Such brush clamp for example has been disclosed among EP 24 121 B1, the WO84/00445 and EP 482 235 A1.
The common ground of all these brush clamps is, is being approximately perpendicular at the ccontaining opening part that forms between the guide rail on the plane of motor axis stretching, extension.The guide groove that such configuration mode makes brush sees on the front end face and rear end face that is located at corresponding brush respectively along the direction of rotation of commutation, that is guide groove and brush the interface position of downside of the sub-side of commutation see mutually along direction of rotation and stagger.The fact shows that this brushgear that has guide rail is compared with the brush that is used for stove of routine, has higher wear of brush and is easy to generate spark.For this reason, the brush clamp that has guide rail up to now only adopts in lower-powered motor.
The present invention is intended to overcome above-mentioned shortcoming of the prior art, therefore, the object of the present invention is to provide a kind of motor that has the brush clamp of the band guide rail that reduces wear of brush, the formation of reduction spark, cheapness.
Another object of the present invention is to be provided for the brush clamp of above-mentioned motor.
A kind of mechanical commutation motor that has a brush clamp is provided according to an aspect of the present invention, this brush clamp has corresponding pairs ground roughly along the guide rail that becomes direction extends parallel radially with motor axis, corresponding two guide rails form the ccontaining opening of brush betwixt and are designed in order to longitudinally to engage with the respective guide slots of brush, it is characterized in that the ccontaining opening that forms roughly is in one by in motor axis and the plane that constitutes perpendicular to a vertical line of this motor axis between guide rail.
According to a further aspect in the invention, a kind of brush clamp that is used for the motor of mechanical commutation also is provided, this brush clamp has a pair of separately guide rail apart from extends parallel, between guide rail, form a ccontaining opening, it is characterized in that, brush clamp has two tabular thigh portions which is provided with guide rail, and thigh portion interconnects at distolateral bridgeware by the bending that roughly meets at right angles.
The favourable structural development and the improvement of motor of the present invention are described below.At least the bridgeware of this sub-side of commutation roughly becomes U-shaped ground to be provided with round the capacity opening that has brush.Be provided with the groove that the edge opens wide in the zone of the extending area of this bridgeware in thigh portion, these grooves can bend the exterior domain of burst portion with respect to the inner region as guide rail.The side towards ccontaining opening at this bridgeware is provided with a grip block, and this grip block curves roughly V-arrangement and is used for the brush stopper.Be formed with a grip block on the bridgeware above another is located at brush, this grip block is used for support spring.Be formed with a flat plug on one of in thigh portion, this flat plug is in order to the pin bushing contact, and this pin bushing is as the electric contact piece of the twisted wire that is electrically connected with brush.Brush clamp is the punching press bending member of being made by sheet material.
According to structure of the present invention, can make brush clamp reduction wear of brush, the formation of reduction spark, the cost of the band guide rail of mechanical commutation motor low, and be enlarged its range of application.
The present invention will be described in detail by an embodiment below in conjunction with the accompanying drawings.In the accompanying drawings,
Fig. 1 illustrates the perspective view of the brush clamp of a motor;
Fig. 2 is the end view of brush clamp;
Fig. 3 is the front view of brush clamp;
Fig. 4 is the cutaway view of the IV-IV line intercepting along Fig. 3.
In Fig. 1, brush clamp indicates with label 10, is used to clamp a brush 11.Brush clamp 10 has the thigh portion 12,13 of two strips, and these two bursts of parts separate a distance and are parallel to each other stretching, extension to form the ccontaining opening 14 of a brush 11 betwixt.Thigh portion 12,13 distolaterally interconnects by bridgeware 15,16 at it.Brush clamp 10 is generally speaking made by board-like material, and its basic configuration for example draws by raw material are carried out punching press, subsequently bridgeware 15,16 is carried out bending.Brush clamp 10 the most handy sheet metals are made, but also can make with plastic material.The part towards ccontaining opening 14 of thigh portion 12,13 is designed for guide rail 17,18 (see figure 4)s that engage with respective guide slots 19,20 in the brush 11. Guide rail 17,18 and guide groove 19, the 20 common vertical guiding devices that constitute brush 11 allow brush 11 to move axially in ccontaining opening 14.For guaranteeing moving axially of brush 11, the bridgeware 15 of the sub-side that commutates at least roughly becomes U-shaped to stretch round ccontaining opening 14.
In the zone of the extending area of the bridgeware 15 of thigh portion 12,13, the position of thigh portion 12,13 in the middle of roughly has the groove (see figure 3), makes the outer intercept can be towards U-shaped jumper 24 bendings and interior intercept formation guide rail 17,18.Interior guiding zone with outside bend corresponding groove 35,36 between the zone and in Fig. 3, can know and see.
Importantly, guide rail 17,18 roughly is located in the plane that is made of motor axis 22 perpendicular lines 37.Thus, the seamed edge the 31, the 32nd that the direction of rotation between the downside of its distolateral 11a and the sub-side of its commutation, that be roughly parallel to motor axis 22, edge commutation 21 of brush 11 is setovered, continual.Owing to the guide groove 19,20 that stretches exactly, 11 seamed edge 33,34 places in 11b up and down, side side of brush are interrupted.
Preferably two brush clamps 10 with respect to commutation son 21 along the diametric(al) setting of staggering.Described brush clamp 10 can be by a unshowned supporting member, for example supporting lid or housing member interconnect.Under a stable condition, it may be favourable that brush clamp 10 is tilted a little with respect to the plane that is made of motor axis 22 perpendicular lines 37.
