The first shaft body is rotationally arranged on a rack and has a radially extending first eccentric block, and the second shaft body is arranged in parallel with the first shaft body on the rack and has a radially extending second eccentric block. The driving mechanism is in transmission connection with the first shaft body and / or the second shaft body; when one of the shaft bodies is driven, the other shaft body is driven by a motion transmission mechanism to rotate in the opposite direction at the same angular velocity, so that the centrifugal forces generated by the first eccentric block and the second eccentric block are combined into centrifugal resultant forces with equal size and opposite direction in the inertia force direction, the effective cancellation of the inertia force is realized, and the centrifugal forces are cancelled in the direction perpendicular to the inertia force direction, thereby avoiding the introduction of secondary vibration.

Description

Technical Field

[0001] This application belongs to the field of mechanical vibration control technology, specifically relating to an inertial force balancing mechanism based on reciprocating motion. Background Technology

[0002] When the actuator (such as a gravity screen) mounted on the frame reciprocates, it generates inertial force that acts on the frame, causing continuous vibration of the frame and its mounting surface. Under long-term operation, this vibration stress can lead to fatigue of the connecting structure, abnormal noise, and even weaken the overall structural strength of the frame.

[0003] To balance this inertial force, existing technologies typically employ an eccentric throwing block mechanism. In this mechanism, the throwing block rotates synchronously with the drive system, and the centrifugal force it generates, in a specific direction, forms a force opposite to the inertial force of the actuator, thereby partially or completely canceling it out and suppressing vibration.

[0004] The inventors discovered that while this single eccentric slinger provides a balancing force in the target direction, the centrifugal force component perpendicular to the target direction cannot be canceled out. It will be transmitted to the frame as an additional inertial force through the motion mechanism, causing the frame to generate new vibrations in the vertical direction. Utility Model Content

[0005] This application provides an inertial force balancing mechanism based on reciprocating motion, which aims to eliminate the component of centrifugal force perpendicular to the target direction, ensuring that no additional inertial force is generated on the frame, thereby improving the stability of the actuator on the frame during operation.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: An inertial force balancing mechanism based on reciprocating motion is provided to eliminate the inertial force between the actuator and the frame, comprising: A first shaft is rotatably mounted on the frame; the first shaft has a first eccentric block extending radially outward therefrom; A second shaft, rotatably mounted on the frame and parallel to the first shaft; the second shaft has a second eccentric block extending radially outward therefrom; and A drive mechanism is driven to the first shaft and / or the second shaft; when the drive mechanism is driven to one of the first shaft and the second shaft, a motion transmission mechanism is also provided between the first shaft and the second shaft; When the drive mechanism is activated, the first shaft and the second shaft rotate in opposite directions at the same angular velocity to form a centrifugal resultant force that is opposite in direction and equal in magnitude to the inertial force; at the same time, in the direction perpendicular to the inertial force, the centrifugal forces of the first eccentric block and the second eccentric block cancel each other out.

[0007] In one possible implementation, the drive mechanism includes: The first rotating motor is fixedly mounted on the frame and is connected to the first shaft or the second shaft for transmission.

[0008] In one possible implementation, the drive mechanism includes: A unidirectional transmission structure is used for transmission connection with the drive system of the actuator, and also for transmission connection with the first shaft or the second shaft, so that when the drive system is started, the first shaft or the second shaft rotates synchronously.

[0009] In one possible implementation, the unidirectional transmission structure includes: A first driving gear is connected to the drive system for transmission; and The first driven gear is coaxially connected to the first shaft or the second shaft, and meshes with the first driving gear.

[0010] In one possible implementation, the motion transmission mechanism includes: The first transmission gear is coaxially connected to the first shaft; and The second transmission gear is coaxially connected to the second shaft and meshes with the first transmission gear; The first transmission gear and the second transmission gear have the same number of teeth so that the rotational speeds of the first shaft and the second shaft are equal.

[0011] In one possible implementation, the motion transmission mechanism includes: The first pulley is coaxially connected to the first shaft. The second pulley is coaxially connected to the second shaft, and its outer diameter is equal to that of the first pulley; and A timing belt is wrapped around the outer periphery of the first pulley and the second pulley in a cross-wrap manner so that the rotation directions of the first shaft and the second shaft are opposite; and the timing belt is in a taut state.

[0012] In one possible implementation, the drive mechanism includes: Two second rotating motors are fixedly mounted on the frame and are respectively connected to the first shaft and the second shaft for transmission.

[0013] In one possible implementation, the drive mechanism includes: A bidirectional transmission structure is used for transmission connection with the drive system of the actuator, and is also transmission connection with the first shaft and the second shaft respectively, so that when the drive system is started, the bidirectional transmission structure drives the first shaft and the second shaft to rotate in opposite directions and at the same angular velocity.

[0014] In one possible implementation, the bidirectional transmission structure includes: The second drive gear is connected to the drive system for transmission; and Two second driven gears are coaxially connected to the first shaft and the second shaft, respectively, and both mesh with the second driving gear; In this configuration, the transmission ratios between the two second driven gears and the second driving gear are equal.

[0015] In one possible implementation, there are multiple first eccentric blocks and multiple second eccentric blocks, and the number of each is equal and they correspond to each other in pairs; The product of the mass and eccentricity of each of the first eccentric blocks is equal to the product of the mass and eccentricity of the corresponding second eccentric block.

[0016] In this embodiment, the drive mechanism or the drive mechanism in conjunction with the motion transmission mechanism can cause the first shaft and the second shaft to rotate at the same angular velocity but in opposite directions, thereby causing the first eccentric block and the second eccentric block to simultaneously generate centrifugal force acting on the frame.

[0017] In the direction of inertial force, the centrifugal forces of the first eccentric block and the second eccentric block are in the same direction and of the same magnitude, thus combining to form a centrifugal resultant force that is opposite in direction and equal in magnitude to the inertial force. This centrifugal resultant force can actively and in real time counteract the inertial force generated by the actuator, achieving the technical objective of counteracting the inertial force, eliminating harmful vibrations, and reducing the adverse effects of the actuator on the frame during operation.

[0018] Meanwhile, in the direction perpendicular to the inertial force, the centrifugal forces of the first eccentric block and the second eccentric block are opposite in direction and equal in magnitude, thus canceling each other out, avoiding the generation of additional inertial forces, and ensuring the smooth operation of the actuator.

[0019] The reciprocating motion-based inertial force balancing mechanism provided in this embodiment, compared with the prior art, generates a centrifugal resultant force of equal magnitude and opposite direction to the inertial force by driving the first and second shafts to rotate at the same angular velocity and in opposite directions, thereby directly canceling vibration at its source. Simultaneously, it ensures that the centrifugal forces generated perpendicular to the direction of the inertial force cancel each other out, avoiding the introduction of secondary vibrations, significantly improving the stability of the equipment during operation, and extending the service life of each component.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0026] Please refer to the following: Figures 1 to 6 The inertial force balancing mechanism based on reciprocating motion provided in this application will now be described. The inertial force balancing mechanism based on reciprocating motion proposed in this application is used to eliminate the inertial force between the actuator and the frame, and includes a first shaft 1, a second shaft 2 and a drive mechanism.

[0027] The first shaft 1 is rotatably mounted on the frame via a bearing seat, and its axial direction is perpendicular to the direction of the inertial force. The first shaft 1 is provided with a first eccentric block 10, which is detachably connected to the first shaft 1 or fixedly connected to it, and extends outward along the radial direction of the first shaft 1 so that when the first shaft 1 rotates, it generates a matching centrifugal force.

[0028] The second shaft 2 is rotatably mounted on the frame via a bearing seat, and its axial direction is parallel to that of the first shaft 1. The second shaft 2 is provided with a second eccentric block 20, which is detachably connected to the second shaft 2 or fixedly connected to it, and extends outward along the radial direction of the second shaft 2, so that when the second shaft 2 rotates, it generates a centrifugal force that matches that of the first eccentric block 10.

[0029] The drive mechanism is connected to the first shaft 1 and / or the second shaft 2 in a transmission connection; when the drive mechanism is only connected to one of the first shaft 1 and the second shaft 2 in a transmission connection, a motion transmission mechanism is also provided between the first shaft 1 and the second shaft 2.

[0030] Specifically, the connection methods between the drive mechanism and the first shaft 1 and the second shaft 2 can be divided into the following three cases: (i) The drive mechanism is connected to the first shaft 1, and the first shaft 1 and the second shaft 2 transmit kinetic energy through a motion transmission mechanism; (ii) The drive mechanism is connected to the second shaft 2, and kinetic energy is transmitted between the first shaft 1 and the second shaft 2 through a motion transmission mechanism; (iii) The drive mechanism is connected to both the first shaft 1 and the second shaft 2, and there is no transmission connection between the first shaft 1 and the second shaft 2.

[0031] When the drive mechanism is started, any of the above three situations can drive the first shaft 1 and the second shaft 2 to rotate in opposite directions and at the same angular velocity, so that the centrifugal forces generated by the first eccentric block 10 and the second eccentric block 20 are combined into centrifugal resultant forces (i.e., balancing forces) of equal magnitude and opposite direction in the direction of inertial force; at the same time, in the direction perpendicular to the inertial force, the centrifugal forces of the first eccentric block 10 and the second eccentric block 20 cancel each other out.

[0032] In this embodiment, the drive mechanism works independently or in coordination with the motion transmission mechanism to precisely control the first shaft 1 and the second shaft 2 to operate stably with the same angular velocity and opposite rotational directions. In this motion state, the first eccentric block 10 and the second eccentric block 20, respectively fixed on the first shaft 1 and the second shaft 2, simultaneously generate centrifugal force acting on the frame.

[0033] Specifically, in the direction of the inertial force generated by the reciprocating motion of the actuator, since the first shaft 1 and the second shaft 2 rotate in opposite directions, the first eccentric block 10 and the second eccentric block 20 can generate centrifugal force components in the same direction. By precisely designing the mass and eccentricity of the eccentric blocks, it is ensured that these two centrifugal force components are equal in magnitude, thus superimposing to form a centrifugal resultant force that is opposite in direction and completely equal in magnitude to the inertial force of the actuator. This centrifugal resultant force can dynamically and in real time counteract the periodic inertial force generated by the actuator during operation, achieving active suppression of the vibration source. This mechanism effectively eliminates harmful vibrations caused by the transmission of inertial forces, significantly reduces the dynamic load borne by the frame of the actuator during operation, and improves the stress environment of the overall structure.

[0034] Meanwhile, on a plane perpendicular to the direction of the inertial force, the centrifugal force components generated by the first eccentric block 10 and the second eccentric block 20 are in opposite directions. Since the rotational speeds of the first shaft 1 and the second shaft 2 are the same and the eccentric block parameters are matched, these two lateral centrifugal force components are equal in magnitude and opposite in direction, thus canceling each other out and preventing the generation of any net inertial force in the lateral direction. This characteristic fundamentally avoids the problem of traditional single-axis balancing mechanisms often introducing secondary vibrations in the vertical direction when balancing vibrations in one direction, ensuring that the actuator maintains a high degree of stability throughout its operation.

[0035] The reciprocating motion-based inertial force balancing mechanism provided in this embodiment, compared with the prior art, not only generates a centrifugal resultant force that perfectly matches the inertial force in the target direction by driving the first shaft 1 and the second shaft 2 to rotate at the same angular velocity but in opposite directions, thus achieving root cause cancellation of vibration, but also eliminates additional vibration in the orthogonal direction through a mechanical self-balancing mechanism. This mechanism effectively solves the problems of vibration control and force transmission optimization, significantly improves the stability and reliability of the equipment during operation, and extends the fatigue life of the frame and connecting components by reducing alternating stress loads.

[0036] In some embodiments, such as Figure 1 and Figure 2 As shown, the drive mechanism includes a first rotary motor 3.

[0037] The first rotary motor 3 is fixedly mounted on the frame by a mounting base, and the output shaft of the first rotary motor 3 is connected to the first shaft 1 or the second shaft 2 via a coupling (only the case where the first rotary motor 3 is connected to the first shaft 1 is shown in the figure).

[0038] In some embodiments, such as Figure 4 As shown, the drive mechanism includes a one-way transmission structure 4.

[0039] The one-way transmission structure 4 is used to drive the actuator's drive system to receive the kinetic energy generated by the drive system; and the one-way transmission structure 4 is driven to the first shaft 1 or the second shaft 2 so that the kinetic energy generated when the drive system starts is transmitted to the first shaft 1 or the second shaft 2, thereby achieving synchronous rotation of the first shaft 1 or the second shaft 2.

[0040] Furthermore, such as Figure 4 As shown, the unidirectional transmission structure 4 includes a first driving gear 41 and a first driven gear 42.

[0041] The first drive gear 41 is connected to the output shaft of the drive system via a key connection. It should be noted that the output shaft is parallel to the first shaft 1 and the second shaft 2. It can be an inherent structure of the drive system or a shaft installed in the drive system specifically for power transmission.

[0042] The first driven gear 42 is coaxially connected to the first shaft 1 or the second shaft 2 via a key connection, and the first driven gear 42 meshes with the first driving gear 41 to realize the power transmission between the first shaft 1 and the second shaft 2.

[0043] In some embodiments, such as Figure 1 and Figure 3 As shown, the motion transmission mechanism includes a first transmission gear 51 and a second transmission gear 52.

[0044] The first transmission gear 51 is coaxially connected to the first shaft 1 via a key; the second transmission gear 52 is coaxially connected to the second shaft 2 via a key, and the second transmission gear 52 meshes with the first transmission gear 51.

[0045] The first transmission gear 51 and the second transmission gear 52 have the same number of teeth, ensuring that the first shaft 1 and the second shaft 2 rotate at the same speed.

[0046] In some embodiments, such as Figure 2 , Figure 4 and Figure 7 As shown, the motion transmission mechanism includes a first pulley 61, a second pulley 62, and a synchronous belt 63.

[0047] The first pulley 61 is coaxially connected to the first shaft 1 via a key.

[0048] The second pulley 62 is coaxially connected to the second shaft 2 via a key, and the outer diameter of the second pulley 62 is equal to the outer diameter of the first pulley 61.

[0049] The timing belt 63 is wrapped around the outer periphery of the first pulley 61 and the second pulley 62 in a cross-wound manner to form an "∞" shape structure, so that the rotation directions of the first shaft 1 and the second shaft 2 are opposite; and the timing belt 63 is in a taut state.

[0050] Since the outer diameter of the second pulley 62 is equal to that of the first pulley 61, the rotational speeds of the first shaft 1 and the second shaft 2 are equal when the synchronous belt 63 moves.

[0051] In some embodiments, such as Figure 5 As shown, the drive mechanism includes two second rotary motors 7.

[0052] Both second rotary motors 7 are fixedly mounted on the frame via mounting bases, and the output shafts of the two second rotary motors 7 are respectively connected to the first shaft 1 and the second shaft 2 via couplings.

[0053] In practical applications, the two second rotating motors 7 are controlled in coordination by the electronic control system to achieve the same speed and opposite rotation of the first shaft 1 and the second shaft 2.

[0054] Specifically, one of the second rotary motors 7 is designated as the master station, and the other as the slave station, with a communication link established between them via a real-time bus (such as EtherCAT). While the master station motor encoder feeds back speed and position signals, the slave station motor dynamically adjusts its torque output based on the received data using a closed-loop control algorithm (such as PID control) to ensure its speed is strictly synchronized with the master station. Simultaneously, the control system applies opposite rotation commands to the two second rotary motors 7, ultimately achieving precise counter-synchronous movement of the first shaft 1 and the second shaft 2 without any mechanical connection.

[0055] In some embodiments, such as Figure 6 As shown, the drive mechanism includes a bidirectional transmission structure 8.

[0056] The bidirectional transmission structure 8 is used for transmission connection with the drive system of the actuator, and the bidirectional transmission structure 8 is also transmission connection with the first shaft 1 and the second shaft 2 respectively.

[0057] By adopting the above technical solution, when the drive system is started, the bidirectional transmission structure 8 can drive the first shaft 1 and the second shaft 2 to rotate in opposite directions and at the same angular velocity.

[0058] Furthermore, such as Figure 6 As shown, the bidirectional transmission structure 8 includes a second driving gear 81 and two second driven gears 82.

[0059] The second driving gear 81 is connected to the output shaft of the drive system via a key connection; the two second driven gears 82 are coaxially connected to the first shaft 1 and the second shaft 2 via key connections respectively, and both second driven gears 82 mesh with the second driving gear 81.

[0060] Among them, the transmission ratios between the two second driven gears 82 and the second driving gear 81 are equal, so as to achieve the technical purpose of the first shaft 1 and the second shaft 2 rotating in opposite directions and with the same angular velocity.

[0061] In some embodiments, such as Figures 1 to 6 As shown, there are multiple first eccentric blocks 10 and second eccentric blocks 20, and the number of first eccentric blocks 10 and second eccentric blocks 20 is equal and they correspond to each other in pairs.

[0062] For the corresponding first eccentric block 10 and second eccentric block 20, the product of the mass of the first eccentric block 10 and the eccentricity is equal to the product of the mass of the corresponding second eccentric block 20 and the eccentricity.

[0063] In another embodiment, there are multiple first eccentric blocks 10 and multiple second eccentric blocks 20, and the number of first eccentric blocks 10 and the number of second eccentric blocks 20 are not equal; wherein, the multiple first eccentric blocks 10 are divided into multiple groups, the multiple second eccentric blocks 20 are divided into multiple groups of equal number, and each group of first eccentric blocks 10 has a corresponding group of second eccentric blocks 20.

[0064] For a corresponding set of first eccentric blocks 10 and a set of second eccentric blocks 20, in the aforementioned direction of inertial force, the centrifugal force generated by each set of first eccentric blocks 10 and the centrifugal force generated by the corresponding set of second eccentric blocks 20 will be superimposed to form a centrifugal resultant force that is equal in magnitude and opposite in direction to the inertial force; in addition, in the direction perpendicular to the inertial force, the centrifugal forces of each set of first eccentric blocks 10 and the corresponding set of second eccentric blocks 20 cancel each other out.

[0065] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
