The tilting tool withdrawal groove (2) is processed between a working surface (4) of the commutator and an amature riser (1). The tool withdrawal groove (2) is a tilting tool withdrawal groove, an opening direction thereof deviates from a rotating shaft, and length of an opening end is larger than that of the bottom. The bottom of the tool withdrawal groove (2) is parallel with a central axis of the rotating shaft (6). A side edge of the tool withdrawal groove (2) is disposed on an end portion of the amature riser (1), and is vertical to the central axis of the rotating shaft (6), and an angle between the other side edge and the working surface (4) of the commutator is smaller than 90 DEG. Compared with the prior art, the motor commutator is beneficial for putting an end to defect phenomenon of a mica sheet which is disposed on a combining position of the tool withdrawal groove and the working surface of the commutator, and reducing accumulation of carbon powders on the position, the carbon powders generated by surface friction of a carbon brush and the commutator in an operating process, thereby reducing short circuit phenomenon and reducing fault rate of interturn blasting of the motor commutator.
Description
Technical field
The utility model relates to the commutator for electric motor field, especially relates to a kind of commutator for electric motor with tilting escape.
Background technology
The commutator of existing DC motor and pulsating current motor (following general designation motor) is in the course of processing, carry out lower quarter for the ease of the further mica sheet to commutator, also be convenient to simultaneously motor will produce because of carbon brush and commutator face friction in normal course of operation carbon dust discharge, must process escapes (2) in 90 degree angles between commutator working face (4) and armature rise piece (1), escape after processing (2) is the rectangle of top breach, as shown in Figure 1.
But, if the commutator of being produced with rectangle escape (2) processing mode of above-mentioned upper notch, when the mica sheet to commutator carries out lower quarter, for being in combine with commutator working face (4) mica sheet at position of escape (2), just be easy to occur the damaged phenomenon of mica sheet, as shown in Figure 2.Therefore, cause motor easily to be assembled herein because of the carbon dust that the friction of carbon brush and commutator face produces in running, cause the motor short circuit phenomenon and cause turn-to-turn and blow out fault, cause the significant wastage of electric energy and human resources, and production efficiency is low, brings very large inconvenience for the production of motor.
The utility model content
The technical problems to be solved in the utility model is: for the problem of prior art existence, a kind of commutator for electric motor with tilting escape is provided, reduce the generation of motor short circuit phenomenon, reduce the failure rate that the motor turn-to-turn is blown out, improve the production efficiency of motor.
The technical problems to be solved in the utility model realizes by the following technical solutions: a kind of commutator for electric motor with tilting escape, be processed with escape at the working face of described commutator and 90 degree angles between the armature rise piece, described escape is the tilting escape, its opening direction deviates from rotating shaft, and openend length is greater than bottom lengths.
Preferably, the bottom of described escape is parallel with the central axis of the rotating shaft of commutator for electric motor, and a side of escape is positioned at armature rise piece end and vertical with the central axis of rotating shaft, and the angle between another side and commutator working face is less than 90 degree.
Preferably, the bottom of described escape is parallel with the central axis of the rotating shaft of commutator for electric motor, and a side of escape is positioned at armature rise piece end and vertical with the central axis of rotating shaft, and the angle between another side and commutator working face is the 60-70 degree.
Preferably, the quantity of described escape is one.
compared with prior art, the beneficial effects of the utility model are: because commutator for electric motor has adopted above-mentioned tilting escape, damaged possibility appears in the mica sheet at position of having stopped to combine with the commutator working face at escape, and reduced motor and gathered at this position because of carbon dust that carbon brush and commutator face friction produce in running, thereby reduced the generation of motor short circuit phenomenon, reduced the failure rate that the commutator for electric motor turn-to-turn is blown out, greatly improved the production efficiency of motor, reduced manufacturing cost, and guarantee the operational reliability of motor.

Embodiment
, in order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the drawings and specific embodiments, the utility model is elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
A kind of commutator for electric motor with tilting escape, be processed with escape 2 at the working face 4 of described commutator and 90 degree angles between armature rise piece 1, described escape 2 is tilting escapes, and its opening direction deviates from rotating shaft 6, and openend length is greater than bottom lengths.The bottom of described escape 2 is parallel with the central axis of the rotating shaft of commutator for electric motor 6, and a side of escape 2 is positioned at armature rise piece 1 end and vertical with the central axis of rotating shaft 6, and the angle between another side and commutator working face 4 is less than 90 degree.
As shown in Figure 3, a kind of commutator for electric motor with tilting escape, armature rise piece 1 at commutator offers an escape 2 with the binding site of commutator working face 4, the bottom of described escape 2 is parallel with the central axis of the rotating shaft of commutator for electric motor 6, one side of escape 2 is positioned at armature rise piece 1 end and vertical with the central axis of rotating shaft 6, and the angle between another side and commutator working face 4 is the 60-70 degree.After commutator for electric motor has adopted this kind tilting escape, because inclined side and the angle between commutator working face 4 of escape 2 are spent less than 90, therefore, in motor operation course, the carbon dust that friction produces for the carbon brush because of motor and commutator face, just discharge from the inclination avris of escape 2 at an easy rate, thereby reduced too much carbon dust gathering at this position, be conducive to reduce the generation of motor short circuit phenomenon, and reduce the failure rate that the commutator for electric motor turn-to-turn is blown out; Simultaneously, adopt the commutator for electric motor of this kind tilting escape, because the opening direction of escape 2 deviates from rotating shaft 6, and openend length is greater than bottom lengths, thereby can guarantee that the angle between the inclined side of the radial transmission line 5 of mica after lower quarter and escape 2 is also less than 90 degree, therefore, when mica sheet is carried out lower quarter, damaged phenomenon appears in the mica sheet at position of can stopping to combine with commutator working face 4 at escape 2, produces damaged 3, mica as depicted in figs. 1 and 2.If there is damaged 3, mica, the carbon dust that produces in running of motor is easy to assemble at damaged 3 places of mica, cause the generation of motor interior short circuit phenomenon and cause turn-to-turn and blow out fault, cause the significant wastage of electric energy and human resources, cause the complete machine production efficiency of motor low, increase the manufacturing cost of motor, and reduced the operational reliability of motor.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; should be pointed out that all any modifications of doing within spirit of the present utility model and principle, be equal to replacement and improvement etc., within all should being included in protection range of the present utility model.
