Abstract
The utility model relates to an installing structure of a rotary motor electrical carbon fixing rack. The installing structure includes an end cover, a carbon brush fixing rack, a carbon brush, a carbon brush clamp, and a bearing, wherein the carbon brush fixing rack supports the carbon brush clamp and the carbon brush respectively, and the bearing is arranged in a bearing hole of the end cover. The installing structure is characterized in that the carbon brush fixing rack matches with circular grooves via end cover bulges and is fixed via a fastener. A matching face of the carbon brush fixing rack and the end cover is arranged on the same side of the bearing. The installing structure is reasonable in design, and the installation size of the fixed and movable carbon brush fixing rack is guaranteed to be accurate and reliable, thus effectively preventing the influence of the assembling factor and the usage environment to the performance of a motor and effectively improving the operation reliability of the motor.
Description
Technical field
The utility model has related to brush revolution armature type motor, specifically is a kind of mounting structure of electrical carbon fixed mount of turning motor.
Background technology
Have the electrical carbon that is used for turning motor now and brush fixed mount when mounted, its plastics and end caps of adopting pass through connected modes that screw is directly locked more, control the installation and positioning structure of carbon brush fixed mount by the coupling mechanism force of two parts.The shortcoming that this kind structure exists is: motor is in long-term work or be heated, when receiving external impacts; To cause the variation of carbon brush fixed mount coupling mechanism force; Thereby cause carbon brush radially, circumference produces displacement, causes brush and each central shaft mutual dislocation, these dislocation make the instability that contacts of carbon brush and commutator; There are brush sound and rotary vibration, the situation that motor properties reduces.
Summary of the invention
The purpose of the utility model is to consider the problems referred to above and provides a kind of and guarantee that motor is in assembling, when running; Effectively prevent the carbon brush fixed mount radially with the circumferencial direction misalignment; Reasonable in design; The installation dimension of guaranteeing dynamic and static carbon brush fixed mount is effectively avoided the influence to motor property of assembling factor and environment for use accurately and reliably, effectively improves the mounting structure of the electrical carbon fixed mount of motor reliability of operation turning motor.
In order to achieve the above object; The technical scheme of the utility model is: it is a kind of mounting structure of electrical carbon fixed mount of turning motor; Comprise end cap, carbon brush fixed mount, carbon brush, brush holder, bearing; The wherein brush holder of supporting respectively and the carbon brush of carbon brush fixed mount, Bearing Installation is in the dead eye of end cap; It is characterized in that protruding and circular groove cooperates and fixes through securing member through end cap for said carbon brush fixed mount and end cap, the mating surface of carbon brush fixed mount and end cap is positioned at the homonymy of bearing.
Be provided with the circular arc of the band convexity more than two in the end of said carbon brush fixed mount; Bottom faces at said end cap is provided with convexity and the circular groove more than two more than two; Said carbon brush fixed mount cooperates with protruding, and the circular arc of said convexity is arranged in circular groove makes fixedly carbon brush fixed mount and end cap radial direction location.
Said securing member is a bolt.
The utility model advantage compared with prior art is: owing to adopt the circular groove part and the cutting of dead eye homonymy of the base plane of end cap; Convexity through end cap circular groove and carbon brush fixed mount is fixed back with end cap carbon brush and is fixed; To carbon brush fixed mount radial direction location, can be easy to, superior maintenance is consistent with the center of rotating shaft on being contained in bearing, prevents eccentric fixing; Prevent to produce dislocation; Can improve the carbon brush positioning accuracy, reduce the carbon brush sound, improve the poor performance that motor causes in the gyratory directions difference.

Fig. 2 is the structural representation of end cap in the utility model;
Fig. 3 is the sketch map of this practical carbon brush fixed mount.
Embodiment
To combine accompanying drawing and embodiment that the utility model is done further detailed description below.
Shown in Fig. 1 to 3; It is a kind of mounting structure of electrical carbon fixed mount of turning motor; Comprise end cap 1, carbon brush fixed mount 2, carbon brush 3, brush holder 4, bearing 6, the wherein brush holder of supporting respectively 4 of carbon brush fixed mount 2 and carbon brush 3, bearing 6 is installed in the dead eye 13 of end cap 1; To be said carbon brush fixed mounts 2 cooperate with circular groove and fix through securing member through end cap is protruding with end cap 1 the utility model characteristics, and the mating surface of carbon brush fixed mount 2 and end cap 1 is positioned at the homonymy of bearing 2.In the present embodiment, said securing member is a bolt 5.
In the present embodiment, be provided with the circular arc 21 of the band convexity more than two in the end of said carbon brush fixed mount 2, in this programme, be provided with four circular arcs that band is protruding; Bottom faces at said end cap 1 is provided with convexity 11 and the circular groove more than two 12 more than two; In this programme, be provided with four convexities 11 and four circular grooves 12; Said carbon brush fixed mount 2 cooperates with protruding 11, and the circular arc 21 of said convexity is arranged in circular groove 12 makes fixedly carbon brush fixed mount 2 and end cap 1 radial location.
During production; The bottom circular groove 12 of end cap 1 forms through machined into dead eye 13; Need not change work piece (die casting); Can make the center of circular groove 12 and dead eye 13 consistent with easily, four protruding circular arcs of band of four circular grooves that are uniformly distributed with 12 of the bottom of end cap 1 and the bottom of carbon brush fixed mount 2 engage mutually, can make carbon brush fixed mount 2 circumferencial directions location.
During installation; End cap 1 is engaged mutually through the protruding circular arc of circular groove 12 and band with carbon brush fixed mount 2 to be located by connecting; To guarantee the stability of carbon brush fixed mount 2 positions; Effectively avoid assembling factor and environment for use to motor noise, about when revolution performance difference influence, effectively improve the motor reliability of operation.
