Description

Technical Field

[0001] The present invention relates to the field of vibration reduction technology, in particular to a damping vibration reduction transmission mechanism, a transmission system and a transmission method. Background Art

[0002] Building vibration refers to the vibration phenomenon that occurs when a building structure is subjected to external excitation (such as ground vibration, wind load, traffic vibration, etc.) or internal excitation (such as mechanical equipment operation, personnel activities, etc.). Building vibration has long been an important issue in the field of construction engineering. Excessive vibration may have an adverse effect on the structural functional performance and personnel comfort of the building, and even endanger the safety of the building. In order to improve the vibration resistance of the structure, researchers and engineers are committed to developing and applying various innovative tuning vibration reduction technologies.

[0003] At present, there are four major ways to realize inertial capacity: gear rack inertial capacity, ball screw inertial capacity, liquid inertial capacity, and electromagnetic inertial capacity. The gear rack and ball screw inertial capacity has a simple structure, the technology is relatively mature, and the application is the most, but it still has significant technical problems: its structure is fixed, the inertial capacity coefficient remains unchanged, and the quality efficiency enhancement ability is not strong. For liquid inertial capacity elements, although there is a technology for variable inertial capacity coefficient, its inertial capacity coefficient changes slowly, the change range is small, and there are strict requirements for sealing. For electromagnetic inertial capacity, although there are some improvements compared with the problems of the first three, its structure is complex, the reliability is low, and it is highly dependent on external energy. In addition, for the existing tuned inertial capacity vibration reduction system, there is generally a single adjustment method, that is, the frequency of the device is adjusted only by adjusting the inertial capacity coefficient. For the tuned inertial capacity vibration reduction system, its inertial capacity coefficient is generally positively correlated with stiffness and damping. Therefore, when we adjust the inertial capacity coefficient, the stiffness and damping should also change accordingly. Summary of the invention

[0047] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0048] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0049] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0050] Example 1

[0051] Reference Figures 1 to 3 , which is the first embodiment of the present invention, provides a damping and vibration reduction transmission mechanism including a first rotating member 100, which can convert vertical linear motion into rotational motion with a horizontal axis; and,

[0052] The second rotating member 200 is transmission-connected to the first rotating member 100 and can convert a rotational motion with a horizontal axis into a rotational motion with a vertical axis; the transmission ratio between the first rotating member 100 and the second rotating member 200 can be changed.

[0053] The first rotating member 100 is a gear column, and the second rotating member 200 includes a multi-stage gear, and the radius of each gear is different. A rack is meshed and connected between each gear and the gear column. In order to ensure that the rack can move and does not fall off, a sliding frame can be set at the corresponding position to ensure that the rack can only slide along the inside of the sliding frame, thereby realizing the transmission between the first rotating member 100 and the second rotating member 200; It should be noted that in this scheme, the second rotating member 200 includes three gears, and the radius of the three gears gradually increases from top to bottom. The three gears are rotatably installed on the outer wall of a rotating shaft, and bearings can be used here to connect the gears and the rotating shaft; and there is space between each gear of the second rotating member 200, such as Figure 1When the rotating shaft moves upward (which can be achieved by a telescopic motor), the upper gear can be meshed with the rack, and the other gear can be disengaged from the rack; Figure 1 In the three states, when the rotating shaft moves downward, the largest gear is engaged with the rack, and the other two gears are disengaged from the rack; in the three states, the transmission ratio between the first rotating member 100 and the second rotating member 200 can be adjusted.

[0054] In summary, if Figure 2 As shown, when the vertical direction deviates up and down, the first rotating member 100 changes the direction into a rotation in the horizontal plane, and the displacement in the vertical direction is transmitted to the first rotating member 100, which can still be driven by a rack and pinion. The first rotating member 100 is rotated by the displacement in the vertical direction. At this time, the first rotating member 100 transmits the transmission to the gear in the second rotating member 200 through the rack, and the transmission ratio is adjusted by adjusting the position of the gear meshing. That is, the linear velocity of the first rotating member 100 transmitted to the gear through the rack is the same, and the gear radius is changed, and the angular velocity of the gear is changed. Therefore, when the linear velocity of the first rotating member 100 is the same, the angular velocity of the gear is adjusted, the gear rotational kinetic energy is changed, and the inertia force output by the device is changed to achieve the optimal vibration reduction effect.

[0055] In scenario application, the above device is installed in the existing technology of vibration reduction, for example, equipment for building vibration reduction. When the equipment is subjected to external vibration, it will drive the first rotating member 100 to rotate, and then transmit the power to the gear in the second rotating member 200 through the rack. The gear in the second transmission member 200 is rotatably connected with the damper, so that there is a reverse force on the rotation of the gear to play a damping role. At the same time, the energy in the transmission process is consumed to better reduce vibration. For different working conditions, the transmission ratio can be adjusted by adjusting the rack to mesh with gears of different radii, thereby adjusting the rotation radius of the gear. At this time, the conversion rate of rotational energy and input translational energy changes, resulting in a change in inertial force, thereby achieving a vibration reduction effect.

[0056] Example 2

[0057] Reference Figures 4 to 6 , which is the second embodiment of the present invention, is different from the embodiment 1 in that the first rotating member 100 and the second rotating member 200 both use multi-stage geared discs, which can adjust the transmission ratio between various types of first rotating members 100 and second rotating members 200, so as to adapt to more external vibration frequencies.

[0058] Preferably, the second rotating member 200 further includes a first-stage adjustment 202 and a second-stage adjustment 203, and the first-stage adjustment 202 and the second-stage adjustment 203 are slidably connected;

[0059] The first-stage adjustment 202 is meshedly connected with the first rotating member 100 , and the transmission ratio between the first rotating member 100 and the second rotating member 200 is adjusted by controlling the meshing position of the first-stage adjustment 202 and the first rotating member 100 .

[0060] Among them, the first rotating member 100 and the second rotating member 200 both include a multi-stage gear, the radius of the gear gradually decreases toward the axial direction, and the tooth groove opening is upward and distributed in a ring; the same gear is connected to an axis through a bearing, a support shaft is built between the two shafts, and the first-stage adjustment 202 and the second-stage adjustment 203 are sleeved on the outer wall of the support shaft. At the same time, the first-stage adjustment 202 is meshed with the gear of the first rotating member 100, and the second-stage adjustment 203 is meshed with the gear in the second rotating member 200. The transmission ratio is adjusted by adjusting the meshing position.

[0061] like Figure 4-5 As shown, for the adjustment of the transmission ratio, preferably, the first-stage adjustment 202 and the second-stage adjustment 203 are both fixed on the outer wall of the support shaft, and the support shaft is slidably installed between the two shafts, and the transmission ratio is adjusted by adjusting the position of the support shaft; at the same time, the support shaft can be fixed between the two shafts, and the first-stage adjustment 202 and the second-stage adjustment 203 are slidably set on the outer surface of the support shaft. At the same time, the first-stage adjustment 202 and the second-stage adjustment 203 are slidably connected by keyway cooperation, so as to adjust the position of the first-stage adjustment 202 and the second-stage adjustment 203 and adjust the transmission ratio.

[0062] In summary, when there is a back and forth fluctuation along the support axis, it will drive the rotation of the first rotating member 100. Here, the vibration source can be connected to a rack, and a gear is set on the lower surface of the first rotating member 100, so that the gear and the rack are meshed and connected, and then the vibration source is introduced into the first rotating member 100. Subsequently, the first rotating member 100 rotates and transmits it to the first-stage adjustment 202, and then to the multi-stage gears in the second rotating member 200 through the second-stage adjustment 203. The rotational inertia is used to react on the vibration source. Similarly, the force transmitted back to the first rotating member 100 will also offset the force transmitted by the vibration source, and the two will react to each other, thereby achieving a vibration reduction effect. If the external frequency changes, the transmission ratio between the multi-stage gears in the first transmission member 100 and the second transmission member 200 can also be adjusted according to external needs, thereby adjusting the rotation angle, thereby better achieving a vibration reduction effect.

[0063] Application scenario: similarly, the existing vibration reduction equipment includes an external vibration source receiving module, an inertia capacity module and a damper; our mechanism replaces the inertia capacity module, when the vibration source is transmitted to the inertia capacity module through the receiving module, the vibration source fluctuation will drive the first rotating member 100 to rotate, and is transmitted to the multi-stage gears in the second transmission member 200 through the first-stage adjustment 202 and the second-stage adjustment 203. The multi-stage gears are rotatably connected with the damper, and the damper further blocks the transmitted force. When the multi-stage gears reverse, the damper blocks the returning force again. At this time, the force transmitted from the vibration source will be used as a force to overcome the damping and rotational inertia, thereby consuming the vibration fluctuation of the vibration source, thereby reducing vibration.

[0064] Example 3

[0065] Reference Figures 7-10 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: the first rotating member 100 includes a transmission disk 101, and the outer wall of the transmission disk 101 is provided with trays 101a with different radii;

[0066] The second rotating member 200 includes a driven disk 201 that can be rotatably connected to the tray 101a;

[0067] The damping assembly 300 includes a damping member 301 capable of realizing energy consumption, and the damping member 301 is connected to the driven disk 201;

[0068] An array of grooves 101a - 1 are formed on the outer wall of the tray 101a .

[0069] Among them, the transmission disk 101 is a circular disk, and an annular tray 101a with a uniformly changing radius is arranged in an array on the upper surface of the transmission disk 101, and the upper surface of the tray 101a is concave and uniformly arrayed with grooves 101a-1; that is, a plurality of trays 101a are arranged in an array in the axial direction, and a circular array of grooves 101a-1 is arranged on the upper surface of the tray 101a; similarly, the structure of the driven disk 201 is the same as that of the transmission disk 101, but the setting position is different.

[0070] The damping member 301 may be an air bag or a damper with air holes, and its main function is to dissipate energy when the force is pushed in, and also to dissipate energy when the force is pulled out in the reverse direction.

[0071] When the force input by the driving disc 101 is input to the damping member 301 through the driven disc 201, the damping member 301 releases the transmitted force, thereby reducing the amplitude of the fluctuation, thereby achieving vibration reduction.

[0072] Preferably, the driving disc 101 and the driven disc 201 are both rotatably mounted with a rotating shaft 103 in the axial direction; a supporting shaft 104 is slidably mounted between the rotating shafts 103;

[0073] The outer walls of the first-stage adjustment 202 and the second-stage adjustment 203 are both provided with a slider 202a that can engage with the groove 101a-1.

[0074] Among them, the outer wall of the rotating shaft 103 is rotatably connected to the transmission disk 101, the outer wall of the other rotating shaft 103 is rotatably connected to the driven disk 201, and a support shaft 104 is slidably installed between the two rotating shafts 103; the first-stage adjustment 202 and the second-stage adjustment 203 are installed on the outer wall of the support shaft 104, and the outer walls of the first-stage adjustment 202 and the second-stage adjustment 203 are arrayed with sliders 202a that can engage with the groove 101a-1. When the transmission disk 101 rotates, the first-stage adjustment 202 engaged with the transmission disk 101 drives the second-stage adjustment 202 to rotate, thereby driving the driven disk 201 to rotate, thereby transmitting force to the damper, thereby hindering the transmission of force, thereby achieving vibration reduction.

[0075] Preferably, the outer wall of the support shaft 104 is sleeved with a first-stage adjustment 202 and a second-stage adjustment 203; and the first-stage adjustment 202 and the second-stage adjustment 203 are slidably connected;

[0076] A motor is mounted on the outer wall of the first-stage adjustment 202 , and a screw rod 204 is fixedly connected to the motor output shaft. A threaded channel 203 a adapted to the screw rod 204 is provided in the second-stage adjustment 203 .

[0077] Among them, the first-stage adjustment 202 is fixed on the outer surface of the support shaft 104, a motor is fixedly installed on the outer wall of the first-stage adjustment 202, the output shaft of the motor is fixedly connected with a screw 204, and a threaded channel 203a adapted to the screw 204 is made on the side of the second-stage adjustment 203 close to the motor. When the motor is driven, the threaded rod 204 can drive the second-stage adjustment 203 to move, thereby adjusting the meshing position of the second-stage adjustment 203 and the driven disk 201. The advantage of this design is that the position of the support shaft 104 can be slidably adjusted, thereby adjusting the meshing position of the first-stage adjustment 202 and the transmission disk 101, driving the position of the second-stage adjustment 203 and the driven disk 201, and realizing a rough adjustment; then the motor is used to adjust the meshing position of the second-stage adjustment 203 and the driven disk 201 to achieve a precise adjustment of the transmission ratio.

[0078] The outer walls of the rotating disk 101 and the driven disk 201 are both provided with a first gear 101c;

[0079] The damping member 301 and the first gear 101 c are driven by the first rack 302 .

[0080] The first gear 101c is fixedly installed on the lower surface of the driving plate 101 and the driven plate 201, and the first gear 101c is meshed and connected with the first rack 302. At the same time, both ends of the first rack 302 are connected with damping members 301. In this scheme, the damping member 301 is a damper. This is a prior art and will not be described in detail. When the driven plate 201 rotates, it will be transmitted to the first rack 302, and the first rack 302 moves left and right. The damping members 301 at both ends will hinder the movement, thereby realizing energy consumption, further weakening the energy of vibration, reducing the amplitude, and achieving a vibration reduction effect.

[0081] Preferably, the outer wall of the support shaft 104 is provided with a second gear 105, and the second gear 105 and the damping member 301 are transmitted by the first rack 302; and the outer wall array of the second gear 105 is provided with a slider 202a that can mesh with the groove 101a-1.

[0082] The outer wall of the second gear 105 has a slider 201a that can mesh with the driven disk 201; and the way the driven disk 201 is connected to the damping member 301 is changed to the support shaft 104, and a second gear 105 is fixedly installed at one end of the support shaft 104 close to the driven disk 201, and the first rack 302 is meshed and connected with the second gear 105. Similarly, dampers are provided at both ends of the first rack 302. The advantage of this design is that in the process of energy consumption, if the resistance is too large, the transmission may be terminated, and the vibration reduction effect cannot be achieved.

[0083] In summary, when the external environment changes, its own frequency changes. At this time, the sliding support shaft 104 adjusts the meshing position of the first-stage adjustment 202 and the transmission disk 101, and adjusts the meshing position of the second gear 105 and the driven disk 201. The angular velocity of the driven disk 201 is constant, and the meshing position of the second gear 105 changes, which changes the radius. Therefore, the speed transmitted to the damper will also change, and the force of the damper will also change in the same direction, thereby realizing the change of the energy consumption effect of the damper and further improving the vibration reduction effect.

[0084] Example 4

[0085] Reference Figures 1 to 14 , which is the fourth embodiment of the present invention, and provides a damping vibration reduction transmission system including a collecting assembly 400, including a box body 401 arranged outside the damping vibration reduction transmission mechanism, a placement frame 401a arranged on the inner wall of the box body 401, a mass block 402 arranged inside the placement frame 401a, a first elastic member 403 arranged between the placement frame 401a and the mass block 402, an adjustment block 404 arranged between the outer wall of the mass block 402 and the inner wall of the placement frame 401a, and a second rack 405 arranged on the outer wall of the mass block 402 and meshingly connected with the first gear 101c;

[0086] The transmission assembly 500 includes a rotating disk 501 disposed inside the box body 401 and meshingly connected to the second rack 405 , a first connecting rod 502 disposed on the outer wall of the rotating disk 501 , and one end of the first connecting rod 502 away from the rotating disk 501 is connected to the support shaft 104 .

[0087] Among them, a placement frame 401a is fixedly installed on the lower inner wall of the box body 401, and there is a cavity inside the placement frame 401a, the cavity is connected to the inside of the box body 401, and a mass block 402 is installed inside the cavity, and the mass block 402 does not contact the narrow frame 401a; an adjustment block 404 is installed between the mass block 402 and the inner wall of the placement frame 401a, and the adjustment block 404 can be an eccentric wheel or an adjustment block made of deformable material. The main purpose is to limit the distance between the mass block 402 and the inner wall of the installation frame 401a according to the size of the adjustment block 404 during rotation, thereby adjusting the fluctuation range of the mass block 404; this solution uses Figure X The S-shaped adjustment block 404 shown in the figure has a structure of a rectangular object, with arc-shaped rods fixedly installed at both ends, and the width of the arc-shaped rods gradually narrows, wherein two adjustment rods 404 are provided on both sides of the mass block 402, and each adjustment rod 404 is connected to a motor, and the contact position of the adjustment block 404 with the mass block 402 and the inner wall of the placement frame 401a is adjusted by the motor. When the narrower position of the arc-shaped rod contacts the mass block 402 and the inner wall of the placement frame 401a, when the mass block 402 fluctuates, the arc-shaped rod will be deformed, and the mass block 402 can be adjusted appropriately. range of fluctuation; at the same time, a first elastic member 403 is installed between the adjustment block 404 and the mass block 402, and the first elastic member 403 can be a deformable structure such as an airbag or a compression spring. When the arc rod in the mass block 402 is deformed, the first elastic member 403 will be squeezed. If the displacement is too large, the arc rod acts as a buffer, and the maximum compression of the first elastic member 403 is formed as the maximum displacement to ensure the displacement range of the mass block 402; at the same time, the second rack 405 fixedly installed on the outer wall of the mass block 402 passes through the mounting frame 401a and is meshed and connected with the transmission disk 101.

[0088] In order to allow the device to make appropriate adjustments when the external environment changes, a rotating disk 501 is rotatably installed inside the box body 401, and a first connecting rod 502 is rotatably installed on the upper surface of the rotating disk 501. The other end of the first connecting rod 502 is connected to the support shaft 104. When vibration occurs, the box body 401 drives the structure other than the mass block 402 to move synchronously; when moving downward, the mass block 402 has a tendency to move upward relative to other structures due to inertia, and then the second rack 405 starts to drive the transmission disk 101 to rotate, and then transmits it to the damping member 301. This process begins to consume energy, thereby achieving vibration reduction.

[0089] Preferably, the outer wall array of the support shaft 104 is respectively provided with a limiting hole 104a and a limiting block 104b;

[0090] The outer wall of the support shaft 104 is provided with a sleeve 503, and the outer wall of the sleeve 503 is provided with a limiting shaft 504 that can extend into the inside of the sleeve 503, and the limiting shaft 504 and the outer wall of the sleeve 503 are connected by a second elastic member 505;

[0091] The inner wall of the sleeve 503 is provided with a sliding groove 503a for the limit block 104b to slide;

[0092] The sleeve 503 is connected to the first connecting rod 502 .

[0093] Among them, in order to achieve internal structure adjustment without disassembling the equipment after installation, a sleeve 503 is slidably arranged on the outer wall of the support shaft 104, and a limit block 104b is fixedly installed on the outer wall of the support shaft 104. At the same time, a slide groove 503a for the limit block 104b to slide is arranged on the inner wall of the sleeve 503 to ensure that the sleeve 503 can only slide but cannot rotate along the outer wall of the support shaft 104; at the same time, a limit hole 104a is arranged in an array on the outer wall of the support shaft 104, and the limit shaft 504 is connected to the outer wall of the sleeve 504 through a second elastic member 504, and the second elastic member 504 is a compression spring, and the limit shaft 504 passes through the sleeve 504; a magnetic suction block is arranged inside the support shaft 104, that is, magnetic suction can be generated when power is turned on, which is a prior art and will not be repeated; when power is turned on, the limit shaft 504 is adsorbed to the limit hole 1 04a, at this time, the sleeve 503 and the support shaft 104 slide synchronously, and when no power is supplied, the second elastic member 504 pops the limit shaft 504 out of the limit hole 104a, and the sleeve 503 is separated from the support shaft 104; the advantage of such a design is that when the external environment changes and the internal structure needs to be adjusted, the magnetic block inside the support shaft 104 is energized, and then the sleeve 503 is connected to the support shaft 104 so that they can move synchronously, and then the positional relationship between the first-stage adjustment 202 and the second-stage adjustment 203 is adjusted. According to the existing computing requirements, at the appropriate position, the power of the magnetic block inside the support shaft 104 is disconnected, so that the sleeve 503 is disconnected from the support shaft 104, and then the motor of the screw position can be started to adjust the specific position of the second-stage adjustment 203, thereby realizing the adjustment of the internal transmission ratio and achieving better vibration reduction.

[0094] In summary, during installation, the motor is first used to adjust the adjustment block 404 on the same side of the mass block 402 according to the scenario, so as to adjust the maximum stroke of the mass block 402. As the mass block 402 fluctuates up and down relative to the box body 401, the second rack 405 begins to drive the rotating disk 501 and the rotating disk 101 to rotate. Since the limiting shaft 504 is not inside the limiting hole 104a, the second rack 405 transmits the energy to the rotating disk 101, and the rotating disk 101 transmits the energy to the damping element 301 through the driven disk 201, thereby consuming energy and achieving vibration reduction.
