Abstract

The present invention relates to a phase control vibration generator capable of continuously controlling a vibration force vector by adjusting phases of two eccentric rotation bodies, and in the conventional invention of the same purpose, a phase control mechanism is used to directly control the centrifugal force of the eccentric rotation body The present invention has an object of providing a phase control vibration generator of a newly formed type which can solve the disadvantage that the eccentric rotary body drive motor must move along with the eccentric rotary body axis and can be practically used. The method of solving the above-mentioned two disadvantages is that the rotation of the rotation axis bearing of the eccentric rotation body is directly driven instead of driving the tilt of the link of the phase adjustment mechanism so that the centrifugal force is not transmitted to the phase adjustment mechanism, The axis of the driving motor / speed reducer of the rotating body is fixed by being aligned with the axis of the pivot of the phase adjusting device and the sun gear belonging to the phase adjusting device is driven, thereby obtaining the effect of realizing a mechanically robust phase control vibration generator .

Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a vibration generator,

The present invention relates to a configuration of a mechanically robust device for giving a phase difference between two eccentric rotating bodies in an eccentric rotational phase phase controlled vibration generator.

The citation technology which is the background of the present invention is described in "Amplitude Controlled Vibration Generator and its Method" (Patent No. 10-1618944 filed on Feb. 24, 2014, Apr. 29, 2016, Kwak, , Which is an embodiment to implement the principle and the principle that the resultant vector of the centrifugal force of the two rotors can be adjusted by advancing and reversing the phases of the two eccentric rotators rotating in opposite directions. The principle of the citation technique is that when the left eccentric rotation body 100 and the right eccentric rotation body 200 shown in FIG. 1 are rotated in opposite directions to each other, the resultant centrifugal force acting on the frame supporting the shaft 101 and the shaft 201 , And when the rotation starts in a state in which there is no phase difference between the two eccentric rotors, that is, when the eccentric mass lies horizontally to the left and right, respectively, the phases are in the vertical direction and the phases of the left eccentric mass and the right eccentric mass are

Figure 112018014817868-utm00001
, The sum of the centrifugal forces is in the same direction as V in Fig. If two sets of such vibration generators are provided side by side in a horizontal plane, the horizontal components of the centrifugal force can cancel each other and only the vertical components remain. The amplitude of the vertical component,
Figure 112018014817868-utm00002
According to the following equation,

Figure 112018014817868-utm00003
Where m is the mass of one eccentric body module, r is the eccentric radius, and? Is the rotational angular velocity.

According to this principle, even if the rotational speed? Of the eccentric rotation body is constant, the amplitude of the vibration force can be controlled by adjusting the phase angle. Therefore, the vibration generator capable of realizing the phase difference of the cited invention is characterized in that the frequency by the adjustment of the rotational angular velocity and the amplitude by the adjustment of the phase angle can be adjusted independently and continuously.

2A, there is shown a phase adjusting mechanism which is a mechanism for connecting two eccentric rotators causing a phase difference, and the link 5 is inclined in a clockwise direction The planet carrier 13 rotates and the gear 12 rotates in the counterclockwise direction. The left gear 12 'is also rotated in the counterclockwise direction. The two eccentric rotators on the left and right sides of the rotation amount gain phase advance and reverse, respectively.

2a is composed of a worm, which is an angle regulating plate fixed to the link 5, and a worm gear connected to the motor / speed reducer, for adjusting the inclination of the link 5. 2b, the force for holding the centrifugal force P of the eccentric rotation body is very large in actual application, and since the gear 13, the gear 12, and the planetary carrier 13 are required to bear entirely, And it has limitations such as robustness in terms of precision and mechanical strength.

In the cited invention, the motor / speed reducer for driving the eccentric rotation body is connected to one of the shafts 16 and 17 of the eccentric rotation body, and the other shaft is configured to rotate in the reverse direction. In this configuration, the motor / speed reducer must move along with the axis of the connected eccentric rotation body. In order to achieve this, a separate device for moving the motor / speed reducer is required, and the structure thereof becomes unnecessarily complicated and mechanically weak.

These two disadvantages in the citation technology are essential to be solved in order to realize practical use of the principle of the phase control vibration generator.

The present invention for solving the above problem is to directly drive the movement of the bearings 3 and 3 'that support the shaft 16 and the shaft 17 of the two eccentric rotors in the mechanism of Fig. . Further, by matching the fixed position of the eccentric rotation unit driving motor with the axis of the pivot 7, the rotating body can be driven without any additional device for moving the motor in the citation technique.

As described above, according to the present invention, it is possible to solve the mechanical weakness of the phase adjustment device, which is one of the disadvantages in the citation technology, and to secure the fixing of the driving motor of the eccentric rotation body. Through this, a technique can be provided that can put the principle of citation technology into practical use.

The operation of the phase control device 2c, which is a core part of the present invention, will be described as follows. When the motor / speed reducer M / R is operated, the ball screw 9 supported by the bearings 26 and 27 is rotated, and the ball screw nuts 3 and 3 ' . Similarly, the eccentric rotation axes 16 and 17 move close to or farther. At the same time, as the link 5 is inclined, the gears 12 and 12 'are changed in phase. For example, if the link 5 is clockwise

, The gear 12 is rotated in a direction
Figure 112018014817868-utm00005
Bringing forward the phase angle of magnitude. The gear 12 'produces the same angular phase shift.

In this embodiment, the torque for driving the eccentric rotation body is transmitted to the link 5, the gears 11 and 11 ', the planetary gears 12 and 12', and the planetary carriers 13 and 13 ' Other than force, there is a characteristic that no force is applied. Therefore, the phase adjustment mechanism of the present invention has a more robust feature, unlike the phase adjustment mechanism of Fig. 2A, which is a cited invention, receives a large centrifugal force and becomes mechanically fragile.

The operation of the phase control vibration generator will be described with reference to Fig. 3, which is an embodiment of the present invention. The ball screws 9 and 10 are supported by the bearings 26 and 26 'and the bearings 27 and 27' on the frame 1 and the ball screw nuts 3 and 3 ' (4) and (4 ') support the eccentric rotary shafts 16 and 17. Each of the support bearings of the ball screw can be composed of two or more. Needless to say, instead of the ball screw, a mechanical element having a linear movement driving function such as a lead screw can be used. The eccentric rotary shaft may be provided with a module (2) having one or a plurality of eccentric rotating bodies or a module (2 ') having the same configuration. The number of eccentricity rotors can be determined for application purpose and design capacity.

The two eccentric rotary shafts 16 and 17 are connected to a phase regulator. As described in detail above, the phase adjustment mechanism includes pivots 7 and 8 fixed to the frame 1, a link 5 capable of rotating around the pivot, and a sun gear Planetary gears 12 and 12 ', and planetary carriers 13 and 13' that connect the planetary gears 11 and 11 ', the planetary gears 12 and 12', and the planetary gears 12 and 12 '. The phase adjusting device includes the phase adjusting mechanism and the ball screws 9 and 10 for driving them, the ball screw supporting bearings 26 and 26 ', 27 and 27', and the ball screw nut 3), (3 '), (4) and (4'). The operation of the above-described satellite adjusting device is performed by moving the ball screws 9 and 10 with the motor / reducer 14 so that the eccentric rotary shaft is moved closer to or away from the eccentric rotary shaft, The phase of the eccentric rotation body advances or reverses.

The two eccentric rotors are rotated in opposite directions to each other by a reverse rotation belt or chain connected to the pulleys 6 and 6 'fixed to the axes of the sun gears 11 and 11' of the phase adjusting mechanism. Further, the sun gear 11 'of the above-described phase adjusting mechanism is driven from the motor / speed reducer 15 through the pulleys 22 and 23. In the present invention, the driving motor / speed reducer (M / R) 15 is fixed to the frame 1 with its rotation axis coinciding with the rotation axis 20 of the phase adjustment mechanism. In this way, even when the link 5 of the phase adjusting mechanism is inclined, the distance between the pulleys 22 and 23 is kept constant. The selection of such a specific position has a disadvantage in that the motor / speed reducer for driving the eccentric rotary shaft 17 must be moved together with the eccentric rotary shaft 17 in the cited invention, and this problem can be solved.

The present invention provides a practical robust phase control vibration generator that solves the two disadvantages of the citing technique described above.

The phase adjustment mechanism described above has a mechanical singularity when the link 5 and the planet carrier 13 or 13 'are in a straight line. In this configuration, when the eccentric rotary shaft bearings 3 and 3 'are to be moved inward, an infinite force is required, or the link 5 is in an unstable state capable of moving in two clockwise or counterclockwise directions . Therefore, in order to avoid the above-described singularity shape, the initial state of the link 5, that is, the state where there is no phase difference of the eccentric rotation body, can be held in a shape in which the link 5 is tilted at a certain angle, for example, 5 degrees clockwise. According to the equation of Fig. 2d,

Figure 112018014817868-utm00006
= 5 degrees is not so large and the vibration force does not change greatly.

Although a specific embodiment of the phase control vibration generator according to the embodiment of the present invention has been described above, the present invention is not limited thereto, and the present invention is not limited thereto and should be construed as having the widest range according to the basic idea disclosed in this specification do. Skilled artisans may vary the size of each component, etc., depending upon the application, and may combine / disclosed the disclosed embodiments to effect a pattern of a shape that has not been noted, but which, too, does not depart from the scope of the present invention. It will be apparent to those skilled in the art that various changes and modifications may be readily made without departing from the spirit and scope of the invention as defined by the appended claims.
