Abstract
The utility model provides a double-eccentric block type vibration motor. The double-eccentric block type vibration motor comprises a motor body and a motor shaft s out of the motor body; eccentric block sets are arranged on the motor shaft; each of the eccentric block sets comprises two hinged eccentric blocks; the eccentric blocks are in detachably fixed connection with the motor shaft; and the eccentric block sets are fixedly arranged on two ends of the motor shaft. The double-eccentric block type vibration motor provided by the utility model is capable of adjusting the center-of-mass based on the angle of the two eccentric blocks, thereby adjusting the amplitude of the vibration motor in a simple and easy way; after the center-of-mass and the amplitude are adjusted, the two eccentric blocks and the motor shaft are relatively fixed, so the stable center-of-mass of the eccentric blocks is ensured when the vibration motor is working, and the stability of the vibration motor is ensured.
Description
Technical field
The utility model relates to mechanical field, particularly a kind of two eccentric block formula vibrating motors that are applied on the vibrating screen.
Background technology
At present, the vibrating motor that uses on the various vibrating screens, the general technical scheme that adopts is the hard-wired eccentric blocks in motor shaft two ends, because eccentric block weight is certain and barycenter is constant, so eccentric force is non-adjustable, causes the motor amplitude single unchanged; And when need changing amplitude, can only add at the eccentricity balance-weight block of fixed weight assembly parts (generally adopting the scheme of bolt fixed iron piece), complex operation, and because the weight of accessory is certain, can not realize the step-less adjustment of amplitude.
The utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of pair of eccentric block formula vibrating motor, so that the motor amplitude is realized electrodeless adjusting.
The utility model is achieved through the following technical solutions:
Two eccentric block formula vibrating motors comprise body and the motor shaft that stretches out from body, and the eccentric block group is installed on the described motor shaft, and described eccentric block group comprises two hinged eccentric blocks; Be dismountable being fixedly connected with between described eccentric block and the motor shaft; The motor shaft two ends all are installed with the eccentric block group.
Above-mentioned pair of eccentric block formula vibrating motor, described eccentricity balance-weight block is rectangular or the lengthy motion picture shape, and two eccentric block one ends in the same eccentric block group are mutually hinged and be installed on the motor shaft, and the other end has angle to the directional divergence away from motor shaft between two eccentric blocks.
Above-mentioned pair of eccentric block formula vibrating motor, described eccentric block becomes large from the part near motor shaft to the direction quality away from motor shaft.
The beneficial effects of the utility model are:
Between two eccentric blocks hinged and with motor shaft between dismantle and be connected, the angle between two eccentric blocks of the adjustment that can pass through is adjusted the eccentric block barycenter, thereby can adjust the amplitude of vibrating motor, and is simple and convenient.

Fig. 2 is the structural representation of the utility model eccentric block.
In the above-mentioned accompanying drawing, 1, body; 2, motor shaft; 3, eccentric block.
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model provides a kind of pair of eccentric block formula vibrating motor, comprises body 1 and from the motor shaft 2 that body 1 stretches out, the eccentric block group is installed on the motor shaft 2, and the eccentric block group comprises two hinged eccentric blocks 3; Be dismountable being fixedly connected with between eccentric block 3 and the motor shaft 2; Motor shaft 2 two ends all are installed with the eccentric block group.Motor shaft 2 drives eccentric block 3 and rotates when rotating, the eccentric block group of motor shaft 2 one ends is used for regulating horizontal vibration amplitude, and the eccentric block group of the other end then is used for regulating vertical amplitude.
As shown in Figure 2, eccentric block 3 is rectangular or the lengthy motion picture shape, and two eccentric block 3 one ends in the same eccentric block group are mutually hinged and be installed on the motor shaft 2, and the other end has angle to the directional divergence away from motor shaft 2 between two eccentric blocks 3.The concrete connected mode of eccentric block group and motor shaft 2 is as follows, the hinged place of two eccentric blocks 2 is the annulus of hollow, annulus is enclosed within on the motor shaft 2 one on the other, fixes by screw and screw rod between annulus and the motor shaft 2, and screw rod contacts with motor shaft 2 with the screw cooperation is rear; Then eccentric block 3 is relative fixing with motor shaft 2 to tighten screw rod, loosens screw rod and then can make eccentric block 3 and motor shaft 2 relative slidings, thereby adjust two angles between the eccentric block 2.The hinged place eccentric block 3 of two eccentric blocks 2 becomes large from the part near motor shaft 2 to the direction quality away from motor shaft 2.Design can make the barycenter of eccentric block 3 try one's best away from motor shaft 2 like this, when eccentric block 3 is adjusted, is conducive to improve the adjustment precision.Simultaneously also save eccentric block 3 materials, reduced cost of manufacture.
The vibrating motor that uses the utility model to provide when needing to adjust amplitude, unclamps being connected between motor shaft 2 and the eccentric block 3, good according to default angle adjustment after, fixed electrical machinery axle 2 and eccentric block 3 are namely realized adjustment process.During vibrating motor work, owing to be in stationary state between eccentric block 3 and the motor shaft 2, can not produce relative sliding, thereby can guarantee that vibrating motor steadily works.Angle between the eccentric block 3 can be realized any adjusting, to realize the step-less adjustment of vibrating motor amplitude.
On the vibrating motor that the utility model provides, the angle of two eccentric blocks of adjustment that can pass through is adjusted barycenter, thereby can adjust the amplitude of vibrating motor, and is simple and convenient; After adjusting, eccentric block is relative with motor shaft fixing, and in the time of can guaranteeing vibrating motor work, the centroid position of eccentric block is stable, is conducive to the stability of vibrating motor work.
Above-described embodiment only is for illustrating that clearly the utility model creates example, and is not the restriction of the utility model being created embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description, need not also can't give all execution modes exhaustive here.And the apparent variation of being amplified out thus or change still are among the protection range of the utility model creation claim.
