Abstract
The utility model relates to an electric brush of direct current motor, which can accelerate the abrasion with the diverter, pertaining to the technical field of motor production. The utility model comprises a body; one end of the body contacted with the diverter is provided with an arc face with a plurality of teeth on the surface. The end part of the electric brush has comparatively big roughness so as to accelerate the abrasion with the diverter and improve the production efficiency, solving the problem that the reaching of the abrasion between the electric brush and the diverter in the prior art needs labor hour so as to influence the efficiency of the motor production.
Description
Technical field
The utility model relates to that a kind of direct current machine uses quickens brush with the commutator break-in, belongs to the technical field that motor is manufactured.
Technical background
Brush and commutator being slipped and giving in the direct current machine of coil power supply,, the possibility that produces noise and vibration from both slippers is just arranged if the contact condition between brush and the commutator is bad.Therefore, in the motor that will avoid noise and vibration, both contact conditions must be good, will be called aging run-in before product export, reduces to result from the noise and the vibration of slide connecting part.For example, influential electric power steering will carry out burin-in process with in the motor under overload state before dispatching from the factory to driver's operation feeling with vibration at noise.
Therefore in the prior art, the roughness of brush end is less, and between the two frictional force is also less when being the commutator break-in, for the break-in that reaches between brush and the commutator need spend more man-hour, has influenced the efficient that motor is manufactured.
Summary of the invention
The utility model purpose is to provide a kind of end roughness bigger, can quicken brush and commutator break-in, and the brush of enhancing productivity, the break-in for reaching between brush and the commutator that has solved the prior art existence need spend more man-hour, has influenced the problems such as efficient that motor is manufactured.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: comprise body, the end that described body contacts with commutator is provided with arc surface, and described arc surface surface is provided with plurality of teeth.In the brush end roughness that tooth can increase the brush end is set, strengthen the coefficient of friction between brush end and the commutator, thereby when brush and commutator break-in, accelerated the wearing and tearing of brush end, and quickened the break-in speed between brush and the commutator, improved production efficiency.
As preferably, be parallel to each other between the described plurality of teeth, and the bearing of trend of each tooth is parallel with the circular arc line of arcwall face, thereby is worn and torn equably in the brush end, guarantee good contact the between brush and the commutator.
As preferably, evenly arrange between the described plurality of teeth and the length of each tooth identical with the arc length of cambered surface.
Therefore, it is bigger to the utlity model has brush end roughness, can quicken brush and commutator break-in, and characteristics such as enhance productivity.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the A-A view of Fig. 1;
Fig. 3 is that the B of Fig. 1 is to view.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as Fig. 1, Fig. 2 and shown in Figure 3, brush 1 comprises body 11, the end that the end of body 1 promptly contacts with commutator is provided with arc surface 12, arc surface 12 surfaces are provided with a plurality of teeth 13, evenly arrange between the tooth 13 and be parallel to each other, and the bearing of trend of each tooth 13 is parallel with the circular arc line of arcwall face 12, and the length of each tooth 13 is identical with the arc length of cambered surface 12.
In the brush end roughness that tooth can increase the brush end is set, strengthen the coefficient of friction between brush end and the commutator, thereby when brush and commutator break-in, accelerated the wearing and tearing of brush end, and quickened the break-in speed between brush and the commutator, improved production efficiency.
Claims (3)
1. the brush that can quicken with the commutator break-in comprises body, it is characterized in that the end that described body contacts with commutator is provided with arc surface, and described arc surface surface is provided with plurality of teeth.
2. the brush that quickens with the commutator break-in according to claim 1 it is characterized in that being parallel to each other between the described plurality of teeth, and the bearing of trend of each tooth is parallel with the circular arc line of arcwall face.
3. the brush that quickens with the commutator break-in according to claim 1 and 2, it is characterized in that evenly arranging between the described plurality of teeth and the length of each tooth identical with the arc length of cambered surface.
