Abstract
The utility model discloses a long-shaft type vibrating-source motor, in particular to a vibration-source motor with an eccentric, comprising the main shaft of the motor arranged in a motor case and an eccentric block connected with the main shaft. The long-shaft type vibrating-source motor is characterized in that the main shaft of the motor is a through shaft structure. Both ends of the main shaft of the motor are supported by bearings, and a plurality of symmetrical eccentric blocks are arranged at the symmetric position of the main shaft of both sides of the motor. The long-shaft type vibrating-source motor has the advantages of simple structure, large amplitude surface, beautiful configuration, low failure rate, high reliability, and long operation life which is four times greater than that of a same type motor. Compared with the prior vibration-source motor with identical volume and weight, the long-shaft type vibrating-source motor can generate more powerful and smooth exciting force.
Description
Technical field
The utility model belongs to motor, relates generally to have eccentric vibration source motor.
Background technology
The vibration source motor is a kind of dynamic power machine that is widely used in oil, chemical industry, metallurgy, mine, building, mechanical field.The vibration source motor of prior art, particularly be applicable to the vibration source motor of vibrating screen, need long axial dimension, China Patent No. is ZL99238495.8, denomination of invention is " being applicable to the vibrating motor of vibrating screen ", this vibrating motor adopts be the motor two side ends cover be provided with respectively one with the dead axle of armature spindle coaxial line, the end that dead axle extends in the motor field frame is connected with armature spindle by eccentric block respectively, one end of eccentric block and armature spindle concrete mutually, the other end is by bearing and dead axle structure combining.Though it is by increasing the extended axial dimension of vibrating motor of dead axle, but its dead axle and armature spindle are not integrative-structures, connect by eccentric block, need regulate dead axle when installing and use makes itself and armature spindle keep concentric, its coupling components is many, complex structure, functional reliability is low, the manufacturing cost height.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, the major axis formula vibration source motor that functional reliability is high.
The utility model comprises electric machine main shaft that is positioned at casing and the eccentric block that connects with main shaft, it is characterized in that electric machine main shaft is the axis structure, and there is bearings at its two ends, and symmetric position is provided with the eccentric block of symmetry respectively on the main shaft of rotor both sides.
Eccentric block of the present utility model is the eccentric shaft type structure, is socketed on the electric machine main shaft.The eccentric shaft both sides that are socketed on the electric machine main shaft all are provided with bearings.
The utility model compared with prior art has:
1, adopts the major axis of integral type, increase the motor axial dimension, eccentric block directly is socketed on the main shaft, reduced connecting link and parts, reduced mechanical loss, improved reliability, and reduced material usage, reduced manufacturing cost.
2, the stress of eccentric shaft is the stress of two end supports, uses the eccentric shaft of same diameter, and its rigidity improves greatly, can bear bigger exciting force.
3, because number of bearings is reasonable in design, and the exciting force that each bearing is born reduces, bearing life increases, and has improved whole aircraft reliability.Because the position of bearings is reasonable in design, make stressed even more, the rigidity enhancing of casing, reduced casing distortion in working order, also improved the force-bearing situation in the bearing working process simultaneously.
4, big, the good looking appearance of the utility model amplitude face, low, the long working life of failure rate, its working life is more than 4 times of motor of the same type; That its same volume and weight can produce is more powerful, exciting force stably.Because special performance of the present utility model, the vibration source in the system such as it can be widely used in vibrating screen in the industry fields such as oil field, probing, oil, chemical industry, metallurgy, building, machinery, transmit, select materials.And can be used on flammable hazardous gas place, more than the degree of protection IP55, possess explosion insulation performance (explosive-proof grade: dIIBT4).
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Accompanying drawing is the cross-sectional view of the utility model embodiment.
Embodiment
Among the figure, the main shaft 6 of motor 7 is structure as a whole, and eccentric shaft 3 is fixed in the symmetric position of its rotor both sides main shaft 6.When the main shaft 6 of motor 7 rotates, drive eccentric shaft 3 rotations that are fixed on the main shaft, thereby make whole casing 4 produce exciting forces.Eccentric shaft 3 is by the bearing chamber 2 at its two ends and the bearings in the bearing chamber 5, and there is the bearing gland location at the bearing two ends, at the two ends of casing 4 bearing cap 1 is installed, and plays the flame proof effect, and can play waterproof, prevents that dust etc. from entering in the casing.The fin of fixed band heat dissipation wind channel on the outer surface of casing, the temperature in the time of can effectively reducing the utility model work improves functional reliability.
In addition, also electric machine main shaft of the present utility model directly can be designed to the major axis eccentric structure, reach goal of the invention of the present utility model equally.
Claims (3)
1, a kind of major axis formula vibration source motor, comprise electric machine main shaft (6) that is positioned at casing (4) and the eccentric block (3) that connects with main shaft, it is characterized in that electric machine main shaft (6) is the axis structure, there is bearings at its two ends, and symmetric position is provided with the eccentric block (3) of symmetry respectively on the main shaft of rotor both sides.
2, major axis formula vibration source motor according to claim 1 is characterized in that eccentric block (3) is the eccentric shaft type structure, is socketed on the electric machine main shaft (6).
