Abstract
Disclosed is a box type vibration motor. A vibrator is a box type structure, excitation eccentric blocks are mounted in the middle of a rotary shaft of a box, bearings are positioned at two ends of the excitation eccentric blocks, a motor rotor is mounted on one side of the rotary shaft, a stator coil is in exact fit with the rotor by the aid of a positioning device of the box, and the eccentric blocks are driven to realize inertia vibration.
Description
Affiliated technical field
The utility model relates to a kind of vibrating motor, particularly a kind of box vibrating motor.
Background technology
At present, general vibrating motor all is to adopt the threephase asynchronous both sides to install the vibration eccentric block additional according to the inertial oscillation principle to combine.Because the exciting force of this vibrating motor and eccentric block quality, eccentric arm and motor angular velocity is square proportional, so, the be in operation moment of inertia of eccentric block of motor is very big, the radial pressure that so just makes motor bearings be in operation to be born is not stable, but impact pressure.In order to make the work steady in a long-term of vibrating motor energy, the armature spindle of existing vibrating motor and bearing all will be through accurate design and manufacturings, and particularly big exciting force vibrating motor in order to satisfy vibratory shock load, must be selected the rolling bearing of big model for use.Like this, compare with common electric machine, under equal speed conditions, the linear velocity of vibrating motor bearing ball is higher than common electric machine far away, and this is the main cause that existing vibrating motor bearing temperature rise is too high, damage is frequent.Moreover existing vibrating motor is owing to reasons in structure, and bearing pedestal must be contained in the casing, and according to the intensity needs, it is thicker that casing and bearing pedestal all design, and has increased the difficulty of bearing heat radiation virtually again.Between gland axis hole and the rotating shaft certain interval must be arranged outside the bearing two ends in addition, cause bearing chamber sealing difficulty, dust enters bearing chamber easily, makes that existing vibrating motor damage of bearings is too fast, has a strong impact on the useful life of vibrating motor.
The eccentric block of existing vibrating motor is contained in the two ends of motor, apart from each other, if deviation occurs not on a horizontal line when installing, phenomenon of torsional vibration can appear in vibrating motor, has a strong impact on the normal use of vibrating motor.
Summary of the invention
In order to overcome existing vibrating motor because of bearing heat radiation difficulty, problem such as poorly sealed causes vibrating motor too short and eccentric block apart from each other in useful life, the deficiency that occurs torsional oscillation etc. easily, the utility model provides a kind of box vibrating motor, this vibrating motor is perfect heat-dissipating not only, sealing and dustproof, and the exciting eccentric block at two ends all placed in the middle of the casing, the generation of vibrating motor phenomenon of torsional vibration avoided.
The technical scheme that its technical problem that solves the utility model adopts is: the vibrating body of vibrating motor is a case structure, and all exciting eccentric blocks are installed in the middle of the casing rotating shaft, and bearing is positioned at its two ends.The electromagnet portion of vibrating motor then is installed on motor one side.The vibration casing of case structure is integrated bearing chamber and casing, bearing directly is loaded in the casing, has so not only improved the concentricity between the two bearings, and has saved bearing pedestal, cut the heat radiation wall thickness that increases because of bearing pedestal, made only remaining casing housing one deck of heat radiation thickness of bearing.
Rotor is contained in rotating shaft one side, and stator line bag accurately cooperates with rotor by the positioner of casing.Electromagnetism heat and the split of bearing heat are distributed, further improved the radiating condition of whole vibrating motor.
All in housing, there is not the rotating shaft exposed parts in the rotating part of box vibrating motor, so, there is not the sealing difficult problem in rotating shaft and axis hole gap yet, whole motor seal is tight, has avoided dust to enter the generation of bearing chamber phenomenon by the axis hole gap effectively.
Be installed in three exciting eccentric blocks in the casing, middle thicker one be fixed eccentric block, and two on both sides are the adjustment eccentric block, can be according to need of work with exciting force stepless adjustment in adjusting range.Because exciting eccentric block is installed concentratedly, reduced the torsional oscillation that causes because of the eccentric block angle difference and taken place, improved the serviceability of vibrating motor.
The beneficial effects of the utility model are, the perfect heat-dissipating of vibrating motor bearing, and the complete machine sealing and dustproof, phenomenon of torsional vibration is few, long service life.Simple in structure, easy to manufacture.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, motor stator, 2, rotor, 3, motor shaft, 4, terminal box, 5, axle sleeve, 6, bearing, 7, internal gland, 8, outer gland, 9, fixed eccentric block, 10, the adjustable eccentric piece, 11, cabinet cover, 12, the lower margin hole, 13, sealing ring.
Embodiment
In Fig. 1, motor stator (1) feeds three-phase alternating current by pressing line box (4), form a rotating magnetic field, rotating magnetic field drives rotor (2) rotation, the exciting eccentric block (9) (10) that drives motor shaft (3) simultaneously and be packed on the motor shaft rotates together, form inertial excitation power, with the lower margin hole (12) that is connected with vibratory equipment exciting force is passed to live load by bearing (6).Axle sleeve (5) internal gland (7) plays the rigid bearing effect, and outer gland (8) cabinet cover (11) and sealing ring (13) play the sealing and dustproof effect.Adjust the relative angle of adjustable eccentric piece (10) and fixed eccentric block (9), size that can stepless adjustment exciting force satisfies need of work.
