Abstract
The utility model discloses a micro vibrating motor, which is used for a cell phone, a pager, etc, and the micro vibrating motor comprises a casing body, and a rotating shaft which is arranged in the casing body. A bearing shaft and a bearing sleeve are arranged on the rotating shaft, a motor component which comprises a magnet steel, a coil, a commentator, a commutating segment and a carbon brush board is arranged in the casing body, the upper end of the rotating shaft comes out of the casing body, a polarization block is connected with the upper end of the rotating shaft, the shape of the casing body is like a circular pipe, the shape of the head part of the bearing sleeve is like a cap, and the circumference of the bearing sleeve contacts with the inner wall of the casing body for positioning. The utility model has the advantages that the structures of the casing body and the bearing sleeve are simple, the contacting and locating surface is large, the coaxial degree of the rotating shaft and the casing body can be easily ensured after the processing and assembling, the spoiled product rate can be reduced, the cost is reduced, and the quality is improved.
Description
Technical field: the utility model relates to a kind of vibrating motor, especially for the micro-vibration motor on mobile phone, the beeper.
Background technology: general micro-vibration electric machine casing all strikes out ampuliform, and rotating shaft utilizes the bearing holder (housing, cover) outer wall of bearing provided thereon to contact the location with housing bottleneck inwall.Because bottleneck length is shorter, and the difficult processing of ampuliform structure guarantees the axiality of the relative inner walls of bottleneck inwall, after rotating shaft and electric machine assembly are fitted into housing, the axiality of the relative inner walls of rotating shaft also be cannot say for sure to demonstrate,prove, make the machine operation wearing and tearing excessive, coil is connected in the rotating shaft, if the coaxiality error conference makes coil contact with inner walls, motor can't be worked.Therefore, existing motor adopts the ampuliform shell structure to make percent defective very high, and is very big to the production cost influence, and assembling processing is trouble also.
Summary of the invention: the utility model newly is the axiality problem rambunctious that solves the relative inner walls of rotating shaft of existing micro-vibration motor.The utility model comprises housing and the rotating shaft that is placed in one, rotating shaft is provided with bearing and bearing holder (housing, cover), in housing, also be provided with the electric machine assembly that comprises magnet steel, coil, commutator, commutator segment and carbon brush platform, housing is exposed in the upper end of rotating shaft, be connected with the polarization piece above, housing is the pipe shape, and the bearing holder (housing, cover) head is the cap shape, and its periphery contacts the location with inner walls.
Adopt the bearing holder (housing, cover) of a pipe shape housing and an adjacent cap shape, simple in structure, the contact locating surface is big, and assembling processing all is easy to guarantee axiality, and the rate of obviously reducing the number of rejects and seconds makes cost reduce quality improvement.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: accompanying drawing is the main structure schematic diagram of embodiment.
Embodiment: as shown in the figure, rotating shaft 2 places housing 1, which is provided with bearing 3 and bearing holder (housing, cover) 4, also be provided with the electric machine assembly that comprises magnet steel 5, coil 6, commutator 7, commutator segment 8 and carbon brush platform 9 in the housing 1, rotating shaft 2 upper ends are exposed housing 1 and are connected with polarization piece 10, housing 1 is the pipe shape, and bearing holder (housing, cover) 4 heads are the cap shape, and its periphery contacts the location with housing 1 inwall.Housing 1 and bearing holder (housing, cover) 4 simple in structure, the contact locating surface is big, and the assembling back easily guarantees the axiality of rotating shaft 2 and housing 1 inwall.During work, electric machine assembly drives rotating shaft 2, polarization piece 10 is rotated produce vibration.
