Specific embodiment
Below against attached drawing, by the description of the embodiment, to for example related each structure of a specific embodiment of the invention
The works such as the shape of part, construction, the mutual alignment between each section and connection relationship, the effect of each section and working principle are further
Detailed description:
As shown in attached drawing 1- attached drawing 3, the present invention is a kind of electric brush of power generator of vehicle end cover structure, the automobile current generator
Brush cover structure includes end cap ontology 1, tolerance ring 2, and mounting hole 3 is arranged on end cap ontology 1, and tolerance ring 2 is installed on mounting hole 3
Interior, multiple riveting faces 5 extended to 3 central axial direction of mounting hole are arranged in the mounting hole outer edge 4 of the mounting hole 3,
When tolerance ring 2 is installed in mounting hole 3, riveting face 5 is configured to the structure being resisted against on 2 end face of tolerance ring.Above structure
The riveting face 5 extended to 3 central axial direction of mounting hole is arranged by the mounting hole outer edge 4 in mounting hole 3 in setting, this
Sample, after tolerance ring 2 is installed in mounting hole 3, riveting face 5 can play the role of effective position to tolerance ring 2, avoid tolerance ring
2 loosen or tolerance ring falls off out of mounting hole on end cap ontology, riveting in the more severe working environment of generator
The setting of pressure surface 5 is the formation after tolerance ring 2 is installed in mounting hole 3, and 2 fixing card of tolerance ring is in mounting hole 3, then leads to
5 riveting of riveting face is crossed, twice fixation can effectively avoid tolerance ring 2 from loosening in mounting hole 3 or take off out of mounting hole 3
The appearance for falling problem effectively increases the overall performance and service life of generator, it is no longer necessary to frequently maintenance replacement end cap sheet
Body 1, tolerance ring 2 and rotor bearing, to significantly reduce maintenance cost and use cost.Automobile current generator of the present invention
Brush cover structure, structure is simple, at low cost, and tolerance ring 2 can be effectively prevent pine occur because of Generator Vibration in use
It is dynamic, so that the appearance for the problems such as avoiding generator abnormal sound, tolerance ring inordinate wear, rotor bearing damage, finally effectively improves hair
The working performance and service life of motor.
Boss 6 of the setting of mounting hole outer edge 4 of the mounting hole 3 along mounting hole outer edge 4 one weeks arrangements, public affairs
The bending part 7 along tolerance ring outward bending in 2 one weeks is arranged in 2 end face of difference ring.Above structure setting, tolerance ring by bending part against
On boss, along with the riveting in riveting face, thus effectively tolerance ring can be realized and fixed, and tolerance annulate shaft can be prevented
To or it is radial play occurs, improve fixed performance.
The riveting face 5 is arranged on boss 6, is formed between riveting face 5 and boss 6 and clamps slot 8, tolerance ring 2 it is curved
Folding part 7 is configured to be installed in the structure clamped in slot 8.Such structure setting, after tolerance ring snaps fitted in mounting hole,
It clamps slot to be clamped bending part, effectively realizes the fixed limit to tolerance ring, tolerance ring can be more effectively prevented from
It is loosened in use because of Generator Vibration, to avoid generator abnormal sound, tolerance ring inordinate wear, rotor bearing damage
The problems such as appearance.
When the tolerance ring 2 is installed in mounting hole 3,7 lower end surface of bending part of the tolerance ring 2 is configured to
Structure in the boss lower surface 9 for being fitted in boss 6,7 left side of bending part are configured to against being fitted in boss 6
Structure on boss left side 10.The setting of boss lower surface can not only form with riveting face and clamp slot, realize to tolerance ring
It is reliably fixed, and boss lower surface can prevent tolerance ring axial float, and the setting of boss left side, tolerance can be prevented
Ring radial-play, boss and the cooperation of riveting face realize limit and positioning to the bending part of tolerance ring, tolerance ring are avoided to loosen or take off
It falls.
Multiple riveting faces 5 are arranged in the mounting hole outer edge 4 of the mounting hole 3, and multiple riveting faces 5 are disposed as in side
The structure of shape, riveting face 5 are set as the structure formed by riveting mode.Multiple riveting faces can realize tolerance ring effective
It limits and fixed, avoids tolerance ring rotation and play, improve fixed performance.
After the tolerance ring 2 is installed in mounting hole 3, the mounting hole outer edge 4 of mounting hole 3 is configured to pass through
Riveting mode forms the structure in multiple riveting faces 5.Riveting face 5 is formation, tolerance ring 2 after tolerance ring 2 is installed in mounting hole 3
Fixing card is in mounting hole 3, then passes through 5 riveting of riveting face.
Electric brush of power generator of vehicle end cover structure of the present invention, by the mounting hole outer edge in mounting hole be arranged to
The riveting face that mounting hole central axial direction extends, in this way, riveting face can be to tolerance after tolerance ring is installed in mounting hole
Ring plays the role of effective position, and tolerance ring is avoided to loosen in the more severe working environment of generator or tolerance ring
It falls off out of mounting hole on end cap ontology, the setting in riveting face is formation, tolerance ring after tolerance ring is installed in mounting hole
For 2 fixing cards in mounting hole, then through riveting face riveting, twice fixation effectively can avoid tolerance ring in mounting hole
Interior loosening or the appearance for the problem that falls off out of mounting hole, effectively increase the overall performance and service life of generator, no longer need
Replacement end cap ontology and tolerance ring and rotor bearing are frequently repaired, use cost has been significantly reduced.Vapour of the present invention
Vehicle generator brush end cover structure, structure is simple, at low cost, can effectively prevent tolerance ring in use due to Generator Vibration
It loosens, so that the appearance for the problems such as avoiding generator abnormal sound, tolerance ring inordinate wear, rotor bearing damage, final effective
Improve the working performance and service life of generator.
Above in conjunction with attached drawing, an exemplary description of the invention, it is clear that concrete implementation of the present invention is not by above-mentioned
The limitation of mode, as long as using the various improvement that the inventive concept and technical scheme of the present invention carry out, or not improved by this
