Summary of the invention
Easily produce vibration and noise in order to overcome existing drag cup vibrating motor rotating shaft rotation, shortened the deficiency of electrical machinery life, the utility model provides a kind of drag cup vibrating motor, this drag cup vibrating motor can not only reduce vibration and the bad noise that the rotating shaft rotation produces to greatest extent, prolong electrical machinery life, and can make simple to operateization, fewization of program letter, reduce product cost.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of drag cup vibrating motor, by shell cylindraceous, magnet, rotating shaft, the drag cup coil, compositions such as end cap, rotating shaft one end stretches in the housing and in the end and is provided with commutator, the other end is positioned at housing eccentric vibration block is installed outward, be positioned at the magnet outside and keep the drag cup coil of slight gap to combine with rotating shaft end commutator with magnet, coil tap is connected with commutator segment on being arranged at commutator, end cap seals shell one end, be fixed on the end cap after brush that closely contacts with commutator segment and the connecting line welding, be characterized in the enclosure and the coaxial plasticity support that is provided with the band connected in star of shell, magnet is installed in the annular groove, coaxial respectively shaft hole and the dead eye of being provided with in the two ends of plasticity support, be communicated with by shaft through-hole between shaft hole and the dead eye, in dead eye, be provided with bearing, rotating shaft passes shaft hole, shaft through-hole and bearing are rotated by shaft hole and bearing supporting.
In order to guarantee the axiality of shell and magnet, rotating shaft, the plasticity support is to adopt coaxial injection moulding fixed housing of synthetic resin and magnet to form.
The utility model adopts the shaft hole and the dead eye of coaxial setting on the coaxial fixed housing of plasticity support, magnet and the plasticity support, guaranteed axiality, reduced the vibration that the rotating shaft rotation produces to greatest extent by the rotating shaft that bearing supported that is provided with in shaft hole and the dead eye and magnet and shell; Because of rotating shaft is rotated by plasticity rack shaft hole and bearing supporting, reduce the bad noise that produces because of friction, prolong electrical machinery life.The utility model plasticity support is to adopt coaxial fixed magnet of injection moulding of synthetic resin and shell to form in addition, needn't reprocess bearing holder (housing, cover) and assembling shell, bearing holder (housing, cover) and magnet, operation is oversimplified, fewization of operation letter, improve production efficiency, reduced product cost.
The beneficial effects of the utility model are, the vibration and the noise of motor are little, the motor long service life, and it is easy to produce assembling, the production efficiency height, product cost is low.
