Abstract
The utility model discloses the fit structures of a kind of starter armature and brush cover, the rotor includes armature spindle and rotor core, the rotor core has shaft hole, the armature spindle cooperation is in the shaft hole, the brush cover is sheathed on the upper end of the armature spindle, the upper port of the shaft hole is equipped with a ring-shaped step, annular wall compatible with the step is convexly equipped on the brush cover, also interference fit is equipped with a gasket ring between the annular wall and the armature spindle, so that armature spindle, rotor core, brush cover three are circumferentially fixed.The utility model fit structure is simple and stable and firm, while by the setting of fillet, so that avoiding and being pulled by brush cover machined burrs, and then effectively protect copper ring, extend service life during copper ring is pressed into.
Description
Technical field
The utility model relates to starter fields, and in particular to a kind of fit structure of starter armature and brush cover.
Background technique
Automobile engine is all pre-actuated and is worked by starter, and starter includes dc motor, magnetic switch
With one-way clutch etc., dc motor includes rotor and stator.Rotor include shaft and be sheathed in the shaft turn
Sub- iron core, stator include wheel hub and install to the annular magnetic steel on the inside of wheel hub.
In the prior art, rotor core be installed on by tight fit in the shaft or rotor core and shaft one
Molding, to make rotor core that the shaft be driven to rotate.But rotor core and the integrated design of shaft, when motor is unexpected
When stalling, which stops suddenly as output shaft, and rotor core has the tendency that continuing to rotate under effect of inertia, for a long time such as
This, is easily damaged motor；And rotor core is to be installed on to turn shaft design by tight fit, often exist fit structure it is complicated,
The short problem of structural instability, service life.
Utility model content
To solve the deficiencies in the prior art, the purpose of this utility model is to provide a kind of starter armature and brush covers
Fit structure, this fit structure structure is simple, stable and firm, and makes copper ring in indentation, from brush cover machined burrs
Direction is pulled, and then effectively protects copper ring, extends service life.
In order to achieve the above objectives, the utility model adopts the following technical solutions: a kind of starter armature and brush cover
Fit structure, the rotor includes armature spindle and rotor core, and the rotor core has shaft hole, the armature spindle cooperation
In the shaft hole, the brush cover is sheathed on the upper end of the armature spindle, and the upper port of the shaft hole is equipped with an annular
Step is convexly equipped with annular wall compatible with the step on the brush cover, between the annular wall and the armature spindle also
Interference fit is equipped with a gasket ring, so that armature spindle, rotor core, brush cover three are circumferentially fixed.
Further, the junction of the annular wall and the brush cover is equipped with fillet.
Further, the annular wall is equipped with limiting slot, and the gasket ring is equipped with limit compatible with the limiting slot
Muscle.
Further, the annular wall is equipped with back-off, and the side wall of the step is equipped with the compatible button with the back-off
Slot.
Further, the gasket ring is copper ring.
The utility model has the beneficial effect that fit structure is simple and stable and firm, while by the setting of fillet, making
During obtaining copper ring indentation, avoids and pulled by brush cover machined burrs, and then effectively protect copper ring, extend use
Service life.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Fig. 2 is the enlarged drawing in the portion A in Fig. 1.
Fig. 3 is the schematic diagram of the rotor core of the utility model.
Fig. 4 is the schematic diagram of the brush cover of the utility model.
Specific embodiment
Specific introduce is made to the utility model below in conjunction with the drawings and specific embodiments.
Shown in referring to figure 1 ~ 4, a kind of fit structure of starter armature and brush cover, the rotor includes armature spindle 1
With rotor core 2, the rotor core has shaft hole 5, and the armature spindle cooperation is in the shaft hole, the brush cover 3
Be sheathed on the upper end of the armature spindle, the upper port of the shaft hole is equipped with a ring-shaped step 6, be convexly equipped on the brush cover with
The compatible annular wall 7 of the step, also interference fit is equipped with a gasket ring 4 between the annular wall and the armature spindle, so that
Armature spindle, rotor core, brush cover three are circumferentially fixed.Fit structure is simple and stable and firm.
In the present embodiment, the junction of the annular wall and the brush cover is equipped with fillet 8.By the setting of fillet, make
During obtaining copper ring indentation, avoids and pulled by brush cover machined burrs, and then effectively protect copper ring, extend use
Service life.
In the present embodiment, the annular wall is equipped with limiting slot 9, and the gasket ring is equipped with compatible with the limiting slot
Limit rib 10.So that the cooperation of gasket ring and brush cover is stronger.
In the present embodiment, the annular wall is equipped with back-off 11, and the side wall of the step is equipped with mutually fits with the back-off
The catching groove 12 matched.So that brush cover is not easy to deviate from from rotor core.
In the present embodiment, the gasket ring is copper ring.
The basic principles and main features and advantage of the utility model have been shown and described above.The technical staff of the industry
It should be appreciated that above-described embodiment does not limit the utility model in any form, it is all by the way of equivalent substitution or equivalent transformation
Technical solution obtained, all falls in the protection scope of the utility model.
