Description

[0002] Motors play a vital role in modern society. The significance of their use is reflected in many aspects. They are not only the power source of various equipment and systems, but also an important symbol of technological progress. They are also a key factor in maintaining the normal operation of industry and society.

[0003] When the motor is working, stability is an important indicator of its performance. Taking into account the uneven mass distribution of the shaft and rotor, it is inevitable that the motor will vibrate when it is working. However, the vibration it generates can be effectively suppressed. Therefore, shock-absorbing motors equipped with shock-absorbing mechanisms came into being.

[0004] Existing shock-absorbing structures mostly use three groups of springs that are vertical in three-dimensional space for buffering. This method requires each group to be adjusted separately when adjusting the buffering force, which is difficult to operate. It is easy to cause the motor vibration amplitude to increase due to the mismatch of buffering forces in various directions. At the same time, when the motor is at high speed, the temperature at its bearings will rise sharply, causing the lubricating grease to fail. At this time, the bearings cannot be well lubricated and wear occurs, and the vibration of the motor is further increased after wear. Summary of the invention

DETAILED DESCRIPTION

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0053] See also Figure 1-Figure 10 In an embodiment of the present invention, a vibration-damping motor based on amplitude control includes: a base 18, a buffer mechanism, a bidirectional drive assembly, and a follower assembly. On the one hand, before installing the motor body 1, the second spring 20 and the third spring 28 can maintain a large amount of compression, thereby improving the stability of the connecting block 16, so as to avoid the difficulty of installation due to the shaking of the connecting block 16 before installing the motor body 1, thereby reducing the difficulty of operation during installation. On the other hand, by synchronously controlling the compression amount of the second spring 20 and the third spring 28, the buffering force can be adjusted, so that after the motor body 1 of different models is installed on the connecting block 16, the vibration generated when it is working can be effectively buffered, thereby improving the stability of the operation of the motor body 1, as follows:

[0054] Two vertical plates 29 are symmetrically mounted on the base 18, and the motor body 1 is disposed on the vertical plates 29;

[0055] The buffer mechanism is connected to the vertical plate 29, and the buffer mechanism includes a first buffer component and a second buffer component arranged vertically;

[0056] The No. 1 buffer assembly includes a guide member 19 fixedly mounted on the base 18, the guide member 19 is slidably connected to the vertical plate 29, and two No. 2 springs 20 are symmetrically arranged on the guide member 19, one end of the No. 2 spring 20 is connected to the vertical plate 29, and the other end is connected to the bidirectional drive assembly;

[0057] The second buffer assembly includes a connection block 16 slidably mounted on the vertical plate 29 and connected to the motor body 1, and a third spring 28 is disposed on each side of the connection block 16;

[0058] The No. 2 buffer assembly further includes a follower block 17 slidably mounted on the vertical plate 29 , the follower block 17 is connected to one of the No. 3 springs 28 , and the follower block 17 is rotationally connected to the abutment wheel 27 .

[0059] In the initial state, the motor body 1 is in contact with the two No. 3 springs 28 through the connecting block 16, so that when the motor body 1 generates vibration in the vertical direction during operation, the two No. 3 springs 28 are used for buffering, thereby buffering the vibration of the motor body 1 in the vertical direction. At the same time, the vertical plate 29 slides on the guide member 19. At this time, the guide member 19 is in contact with the two No. 2 springs 20, so that when the motor body 1 generates lateral vibration in the horizontal direction during operation, the No. 2 springs 20 can buffer, and when the connecting block 16 moves in the vertical direction and the guide member 19 moves in the horizontal direction, no interference occurs, so that when the motor body 1 generates vibration in the radial direction of its rotating shaft, the No. 2 springs 20 and the No. 3 springs 28 are used for buffering, thereby improving the stability of the motor body 1 during operation and reducing the tendency of internal wear of the motor body 1 and loosening of tightening screws due to vibration.

[0060] It should be noted that the main reason for the vibration of the motor body 1 is the uneven mass distribution of its shaft and rotor, at which point vibration is mostly generated along the radial direction of the shaft, while the vibration along the axial direction is relatively small and can be ignored.

[0061] See also Figure 2 , Figure 8-Figure 10 , the bidirectional driving component is connected to the first buffer component, and the bidirectional driving component can adjust the buffering force of the first buffer component;

[0062] The bidirectional drive assembly includes a bidirectional screw rod 23 rotatably mounted on the guide member 19, the bidirectional screw rod 23 is provided with two threaded sleeves 22 threadedly connected thereto, the threaded sleeve 22 is fixedly mounted with an abutment member 21, the abutment member 21 is connected to the No. 2 spring 20, when the bidirectional screw rod 23 rotates, the two threaded sleeves 22 can compress or release the two No. 2 springs 20;

[0063] The follower assembly is connected to the bidirectional drive assembly and the second buffer assembly. The follower assembly is provided with an abutment plate 26, which abuts against an abutment wheel 27 connected to the second buffer assembly, and the abutment wheel 27 can roll on the abutment plate 26;

[0064] The follower assembly includes a lifting plate 25 disposed on the base 18 and fixedly connected to the abutment plate 26, and two inclined grooves 2501 and a guide groove 2502 are symmetrically disposed on the lifting plate 25, and the guide groove 2502 is slidably connected to a sliding connection portion 1901 disposed on the guide member 19;

[0065] The follower assembly further includes a sheave 24 rotatably connected to the abutment member 21 , and the sheave 24 can roll in the inclined groove 2501 ;

[0066] When the bidirectional driving component adjusts the buffering force of the first buffer component, the follower component can synchronously adjust the buffering force of the second buffer component.

[0067] Before installing the motor body 1 on the vertical plate 29, the bidirectional screw 23 can be rotated to make the two abutment members 21 move away from each other. At this time, the opposite ends of the two No. 2 springs 20 will be pulled away by the abutment members 21, so that the initial compression of the No. 2 spring 20 will increase (an external abutment object can be used to prevent the vertical plate 29 from being displaced). At this time, the distance between the two vertical plates 29 is relatively fixed, and the tendency of the vertical plates 29 to move left and right is suppressed.

[0068] When the two abutments 21 move away from each other, the two groove wheels 24 will also move away from each other. When the groove wheel 24 cooperates with the inclined groove 2501, it can drive the abutment plate 26 to move upward. At this time, the abutment plate 26 acts on the abutment wheel 27 to make the follower block 17 move upward, thereby compressing the two No. 3 springs 28, so that in this state, the up and down movement tendency of the connecting block 16 is suppressed.

[0069] That is, in the initial state, the compression degree of the No. 2 spring 20 and the No. 3 spring 28 is the largest, so that the tendency of the connecting block 16 to move left and right and up and down is smaller, which facilitates the installation of the motor body 1 to the connecting block 16 and reduces the difficulty of operation during installation.

[0070] After the motor body 1 is installed, the bidirectional screw rod 23 is controlled to reverse (the abutting object is removed). At this time, the No. 2 spring 20 and the No. 3 spring 28 can be released to a certain extent, and the vibration generated by the motor body 1 is buffered when it is working.

[0071] Since the masses of shafts and rotors of different models are different, the vibrations generated during operation will also be different. At this time, whether the buffering force is too large or too small, the buffering effect will be lost. For this reason, in this embodiment, the No. 2 spring 20 and the No. 3 spring 28 can maintain a predetermined buffering strength according to the model of the shaft and rotor of the motor body 1.

[0072] It should also be noted that in order to match the buffering strength with the vibration amplitude generated when the motor body 1 is working, an amplitude sensor can also be installed on the motor body 1, and a drive motor can be installed on the guide member 19. The drive motor is electrically connected to the amplitude sensor, and the drive motor is controlled by the real-time vibration amplitude received by the amplitude sensor, thereby changing the buffering strength of the No. 2 spring 20 and the No. 3 spring 28 in real time.

[0073] Through the above arrangement, on the one hand, before installing the motor body 1, the No. 2 spring 20 and the No. 3 spring 28 can maintain a large compression amount, thereby improving the stability of the connecting block 16, so as to avoid installation difficulties due to the shaking of the connecting block 16 before installing the motor body 1, thereby reducing the difficulty of operation during installation. On the other hand, by synchronously controlling the compression amount of the No. 2 spring 20 and the No. 3 spring 28, the buffering force can be adjusted, so that after different models of motor bodies 1 are installed on the connecting block 16, the vibrations generated when they are working can be effectively buffered, thereby improving the stability of the operation of the motor body 1.

[0074] See also Figure 3-Figure 7 , a vibration-damping motor based on amplitude control, further comprising: an adjusting sleeve 12, a centrifugal component and a spiral switching component.

[0075] The adjusting sleeve 12 is connected to the motor body 1 , and the adjusting sleeve 12 is connected to the bearing on the motor body 1 through a guide tube 13 , and an adjusting structure is arranged inside the adjusting sleeve 12 ;

[0076] The adjustment structure includes a fixed disk 15 fixedly installed in the adjustment sleeve 12 and a rotating disk 14 rotatably installed in the adjustment sleeve 12, and the rotating disk 14 is sealed and fitted with the fixed disk 15;

[0077] The rotating disk 14 is provided with a first arc-shaped through groove 1401, and the fixed disk 15 is provided with a second arc-shaped through groove 1501. The first arc-shaped through groove 1401 cooperates with the second arc-shaped through groove 1501 to adjust the flow rate of the coolant flowing into the adjusting sleeve 12;

[0078] The centrifugal assembly is connected to the rotating shaft of the motor body 1, and includes a plurality of followers 2 equidistantly arranged on the rotating shaft of the motor body 1, wherein the followers 2 are provided with a slide groove 201 along the length direction thereof, and a slider 3 is slidably installed in the slide groove 201, a counterweight 4 is fixed on one side of the slider 3, and a pulling rod 5 is rotatably installed on the other side;

[0079] The centrifugal assembly further comprises a follower sleeve 7 slidably sleeved on the rotating shaft of the motor body 1 , the follower sleeve 7 is rotatably connected to the pulling rod 5 , and an annular groove 701 is formed on the follower sleeve 7 ;

[0080] A spring 6 sleeved on the rotating shaft of the motor body 1 is connected to the follower 2 and the follower sleeve 7;

[0081] The spiral switching assembly is connected to the centrifugal assembly and the adjustment structure, and drives the adjustment structure to operate when the speed of the motor body 1 changes. The spiral switching assembly includes a rotating shaft 10 rotatably mounted on the motor body 1, and the rotating shaft 10 is connected to the rotating disk 14 through a connecting belt 11, and the rotating shaft 10 is provided with a spiral groove 1001 along its axial direction;

[0082] The spiral switching assembly also includes a ring 8 rotatably sleeved in the annular groove 701 , the ring 8 is connected to a transverse sleeve 9 slidably sleeved on the rotating shaft 10 , a convex shaft 901 is provided in the transverse sleeve 9 , and the convex shaft 901 is slidably matched with the spiral groove 1001 .

[0083] When the motor body 1 is working, its rotating shaft will rotate. At this time, the follower 2 will make a circular motion, and drive the slider 3 and the counterweight block 4 to make a circular motion, and generate centrifugal force at the same time. Under the action of centrifugal force, the slider 3 will move away from the rotating shaft of the motor body 1 along the length direction of the slide groove 201, and pull the follower sleeve 7 toward the follower 2 through the pulling rod 5. At this time, the follower sleeve 7 will drive the transverse sleeve 9 to move synchronously, and with the cooperation of the convex shaft 901 and the spiral groove 1001, the rotating shaft 10 will rotate. The rotating shaft 10 drives the rotating disk 14 to rotate through the connecting belt 11, so that the No. 1 arc groove 1401 can overlap with the No. 2 arc groove 1501, so that the external coolant can flow into the rotating shaft of the motor body 1, cool the bearing position of the motor body 1, and avoid the failure of the lubricating grease due to excessive temperature, which will cause the bearing of the motor body 1 to wear and cause vibration.

[0084] As the rotation speed of the motor body 1 increases, the temperature generated at its rotating shaft will also become higher. At this time, the speed of the slider 3 in circular motion will increase, and the centrifugal force generated will also be greater, which will cause the displacement of the follower sleeve 7 and the transverse sleeve 9 to be larger. At this time, the rotation angle of the rotating disk 14 is larger, so that the overlapping area of ​​the No. 1 arc-shaped through groove 1401 and the No. 2 arc-shaped through groove 1501 is larger, so that more coolant can enter the adjusting sleeve 12 and the bearing of the motor body 1 from the outside, thereby achieving a better cooling effect, further preventing the lubricating grease from failing due to excessive temperature at the bearing, and causing the bearing of the motor body 1 to wear and vibrate.

[0085] It is worth noting that after the coolant enters the bearings in the motor body 1 , it can flow out through the pipeline, thereby realizing the circulating pumping of the coolant and thus realizing cyclic heat exchange.

[0086] Through the above-mentioned arrangement, the rotation speed of the motor body 1 can be automatically matched with the flow speed of the coolant, so that when the motor body 1 rotates at a high speed, the flow speed of the coolant is faster, thereby achieving a better cooling effect on the bearings of the motor body 1, preventing the lubricating grease from failing due to excessive temperature, and preventing vibration caused by wear of the bearings of the motor body 1, thereby reducing the vibration of the motor body 1 during operation to a certain extent.

[0087] A vibration reduction method for a vibration reduction motor as described above comprises the following steps:

[0088] Step 1: Control the bidirectional driving assembly to move, drive the follower assembly to move, make the buffering force of the No. 1 buffer assembly and the No. 2 buffer assembly the largest, and then install the motor body 1 on the vertical plate 29;

[0089] Step 2: According to the model of the motor body 1, the bidirectional driving component is controlled to move so that the buffering force of the first buffer component and the second buffer component matches the model of the motor body 1;

[0090] Step 3: Connect the external coolant pumping device to the adjusting sleeve 12 through a pipeline;

[0091] Step 4: Start the motor body 1. According to the actual rotation speed of the motor body 1 shaft, the centrifugal component can drive the adjustment structure to move through the spiral switching component to change the amount of coolant pumped to the bearing.
