Abstract
The utility model discloses an exciter which comprises a fixed eccentric core connected with a universal drive shaft used for inputting power and a movable eccentric core connected to the fixed eccentric core, wherein the fixed eccentric core is installed at one end of a rotary shaft, and a fixed eccentric core is also installed at the other end of the rotary shaft; the fixed eccentric core is connected with another universal drive shaft, and the fixed eccentric core is also connected with a movable eccentric core; the deflection angles of two movable eccentric cores at both ends of the rotary shaft are opposite. The utility model has the advantages of easy manufacturing, simple structure, convenient disassembly and maintenance, wide adjustment range of the value of exciting force, etc.
Description
Technical field:
The utility model relates to a kind of being installed in and is used to produce exciting force on the vibratory equipment and makes the vibrative vibrator of vibratory equipment.
Background technology:
Vibrator is a kind of exciting force that the generation cycle changes that is used for, and makes the work body produce the equipment of sustained vibration, and the structure of vibrator and form are diversified.Use more vibrator mainly to form in the prior art by members such as eccentric shaft, movable offset object and fixed offset objects, this processing request height that has the structure of eccentric shaft to member, processed complex, and be to link together by eccentric shaft between the vibrator, be not easy to dismounting and maintenance and little to the value adjustable range of exciting force.
Summary of the invention:
The purpose of this utility model is: provide a kind of and be easy to process, simple in structure, be convenient to dismounting and maintenance and the vibrator wide, to overcome the deficiency that above-mentioned prior art exists to the value adjustable range of exciting force.
The utility model is to constitute like this: it comprises the fixed offset object (2) that links to each other with the universal drive shaft (4) of importing power and is connected movable offset object (1) on the fixed offset object (2), fixed offset object (2) is installed in an end of turning cylinder (3), fixed offset object (5) is installed on the other end of turning cylinder (3), fixed offset object (5) links to each other with universal drive shaft (7), be connected with movable offset object (6) on fixed offset object (5), movable offset object (6) is opposite with the deflection angle of movable offset object (1).
The utility model compared with prior art, it has the following advantages: 1, dismounting, replacing are convenient, are easy to processing.Two vibrators connect by universal drive shaft, as long as when dismounting, unload the fixed offset object (band movable offset object) and the connecting bolt of the inside, and easy accessibility, owing to can change mutually between the eccentric son, easy to replace and maintain; And because there is not eccentric shaft, so its processing is simple; 2, the adjustable range to the exciting force value is wide.Adjustment to the exciting force value of vibrator all is to realize by the deflection angle of adjusting movable offset object.When adjusting, generally being per 15 ° is lattice, and under same revolution, 0-180 ° can be divided into 13 lattice altogether, and just the exciting force value has 13 kinds.Traditional vibrator is owing to have only a movable offset object, under same revolution, can only be divided into 13 lattice, its adjustment to the exciting force value also just has only 13 kinds, and the utility model is because its movable offset object and fixed offset object inside and outside respectively have 2, therefore under same revolution, when adjusting, lattice are transferred in the inside, and the outside is with regard to adjustable 13 lattice, the value of adjusting exciting force so just has 13 * 13 kinds, so its adjustable range to the exciting force value is wide.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the adjustment schematic diagram to the value of exciting force;
Accompanying drawing 3 is the structural representation of movable offset object of the present utility model and fixed offset object.
The specific embodiment:
As shown in Figure 1, end at turning cylinder (3) installs and fixes eccentric son (2), on the other end of turning cylinder (3), install and fix eccentric son (5), movable offset object (1) and movable offset object (6) are connected on fixed offset object (2) and the fixed offset object (5) with bolt respectively, and make the deflection angle of movable offset object (1) and movable offset object (6) just opposite, then universal drive shaft (4) is connected on the fixed offset object (2), universal drive shaft (7) is connected fixed offset object (5) upward gets final product.
The utility model generally uses two or four in use simultaneously, and with their relative in twos symmetric arrangement, links together by universal drive shaft (7) between two vibrators of every group, and power is imported by universal drive shaft (4).Movable offset object on every vibrator (1) and movable offset object (6) are when being driven in rotation, because the effect of eccentric inertia force has just produced exciting force, because every group two or four vibrators are relative symmetric arrangement and link to each other by same universal drive shaft (7), revolution when rotating equates and direction is opposite like this, the power on every group of vibrator horizontal direction that makes is cancelled out each other, and power mutual superposition in vertical direction, thereby obtain needed exciting force.
Claims (2)
1. vibrator, it comprises with the fixed offset object (2) that links to each other of universal drive shaft (4) of input power and is connected movable offset object (1) on the fixed offset object (2), fixed offset object (2) is installed in an end of turning cylinder (3), it is characterized in that: fixed offset object (5) is installed on the other end of turning cylinder (3), fixed offset object (5) links to each other with universal drive shaft (7), is connected with movable offset object (6) on fixed offset object (5).
2. vibrator according to claim 1 is characterized in that: movable offset object (6) is opposite with the deflection angle of movable offset object (1).
