Description

Technical Field

[0001] This application relates to the field of gearboxes, and more particularly to a support for a gearbox. Background Technology

[0002] A gearbox, also known as a transmission or speed increaser, is a power transmission mechanism mainly used to achieve speed change, change transmission direction, adjust torque, realize clutch function, and distribute power. Due to its wide range of applications, a gearbox contains a variety of gear components, which makes it relatively large and requires a suitable bracket for support. At the same time, the internal structure of different types of gearboxes is inconsistent, resulting in a variety of shapes and sizes. Existing gear-shaped brackets can only be customized to fit a single type of gearbox.

[0003] The existing support base mainly relies on the rigidity of the structure to hold the gearbox and resist the vibration of the gearbox during use. It lacks effective energy dissipation means and has limited absorption effect on medium and high frequency vibrations and instantaneous impacts. This can cause vibrations to be directly transmitted to the foundation structure or adjacent equipment, which can have an adverse effect on the bearings and gear meshing accuracy of the gearbox itself under long-term operation. Utility Model Content

[0004] To address the issue that rigid clamping has limited effectiveness in absorbing most vibrations, this application provides a support bracket for a gearbox.

[0005] The gearbox support bracket provided in this application adopts the following technical solution:

[0006] A support base for a gearbox includes a support base one and a gearbox body. The support base one is slidably connected to a support base two for supporting the gearbox body. The support base two is provided with a clamping frame for clamping the gearbox body. A plurality of clamping mechanisms for elastically clamping the gearbox body are provided between the support base two and the clamping frame. A baffle for protecting the clamping mechanisms is fixedly connected between the support base two and the clamping frame. A plurality of connecting mechanisms for longitudinal vibration reduction are provided between the support base one and the support base two.

[0007] The clamping mechanism includes a fixed frame for telescopic extension and a movable column slidably connected inside the fixed frame. The outer surfaces of the fixed frame and the movable column are fitted with a reset spring for resetting.

[0008] By adopting the above technical solution, support base one serves as the basic bearing and installation platform for the entire support system, support base two serves as the direct bearing platform and primary vibration damping unit for the gearbox body, the clamping frame is the component that directly contacts and wraps around the gearbox body, the clamping mechanism is used to elastically clamp the gearbox body, realizing the rapid installation, automatic centering and elastic clamping of the gearbox body, the baffle is used to prevent dust, oil, and foreign objects from entering the interior of support base two, contaminating or hindering the moving parts of the clamping mechanism, and ensuring its long-term reliability. At the same time, it can also increase the aesthetics of the overall structure. Fixed frame one and moving column one form a telescopic guide rod to ensure that the clamping mechanism moves in a straight line during clamping and releasing, preventing skew and jamming, and ensuring the reliability and repeatability of the action. Return spring one provides the source of clamping force, its preload ensures that the clamping frame can firmly hold the gearbox, and at the same time, it is compressed when the gearbox is put in, generating a rebound force to achieve self-clamping. The connecting mechanism is used to connect support base one and support base two, and forms a multi-dimensional and efficient longitudinal vibration damping.

[0009] Preferably, the clamping mechanism further includes several fixed seats one fixedly connected inside the support seat two, and a rotating block one fixedly connected to the fixed frame one and the reset spring one is rotatably connected to one side of the fixed seat one.

[0010] By adopting the above technical solution, the rotating block 1 is connected by a hinge, which converts the relative motion between the support base 2 and the fixed frame 1 into the telescopic motion of the clamping mechanism, and allows the fixed frame 1 to adapt to the shape deviation of the gearbox within a certain range.

[0011] Preferably, a plurality of fixed seats 2 are fixedly connected to one side of the clamping frame, and a rotating block 2, which is fixedly connected to the moving column 1 and the reset spring 1, is rotatably connected to one side of the fixed seat 2.

[0012] By adopting the above technical solution, the rotating block 2 converts the relative motion between the moving column 1 and the clamping frame into the telescopic motion of the clamping mechanism, and allows the moving column 1 to adapt to the shape deviation of the gearbox within a certain range.

[0013] Preferably, the connecting mechanism includes several fixed plates one fixedly connected to the bottom surface of the support base two. A fixed cylinder is fixedly connected inside the fixed plate one. A ring is symmetrically slidably connected to the outer surface of the fixed cylinder. A return spring two sleeved on the outer surface of the fixed cylinder is fixedly connected to the opposite side of the ring.

[0014] By adopting the above technical solution, the ring can slide on the fixed cylinder. Its core function is to convert the vertical vibration displacement transmitted from the second support into the horizontal movement of the ring through the linkage mechanism. The second return spring is used to connect the two rings. When the rings move horizontally relative to each other or in opposite directions, the spring is compressed or stretched to absorb and store vibration energy, and then slowly released, thereby consuming most of the vibration energy.

[0015] Preferably, a connecting rod is rotatably connected to the outer surface of the ring, and a fixed seat is rotatably connected to the side of the connecting rod away from the ring.

[0016] By adopting the above technical solution, the connecting rod is the key component for motion transformation. It converts the vertical linear motion of the fixed plate 1 (with the support 2) into the horizontal linear motion of the ring through the lever principle.

[0017] Preferably, a plurality of fixing plates 2 are fixedly connected to one side of the support base 1, the fixing base 3 is fixedly connected to the top surface of the fixing plates 2, and dampers are symmetrically fixedly connected between the fixing plates 2 and the fixing plates 1.

[0018] By adopting the above technical solution, the main function of the damper is to suppress large-amplitude impact displacements (such as instantaneous impacts during startup and shutdown), and to provide viscous damping to further dissipate vibration energy, prevent the return spring from excessive compression and rebound, and improve system stability.

[0019] Preferably, a fixed cylinder is symmetrically fixedly connected to the top surface of the fixed plate two, and a movable column two is slidably connected inside the fixed cylinder two and fixedly connected to the fixed plate one. A return spring three is fixedly connected between the fixed plate one and the fixed plate two and sleeved on the outer surface of the fixed cylinder two and the movable column two.

[0020] By adopting the above technical solution, the fixed cylinder 2, the movable column 2, and the return spring 3 constitute the main vertical vibration damping elements. The return spring 3 directly bears the weight and vertical vibration of the support seat 2 and the gearbox, playing a buffering and supporting role. The movable column 2 slides inside the fixed cylinder 2 to ensure the guidance of vertical movement.

[0021] Preferably, the baffle and the clamping frame are both made of synthetic rubber.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By utilizing the interaction between the rubber clamping frame, the fixed frame, the return spring, and the moving column, the gearbox body is self-adaptively clamped. The rounded corner design of the clamping frame and the hardness of the rubber (Shore hardness range of 40-70A) ensure a tight fit with the shape of the gearbox, reducing vibration transmission.

[0024] 2. When the gearbox body rotates, it drives the support seat two to vibrate, which in turn causes the fixed plate one to move up and down. This, in turn, compresses the moving column two to slide inside the fixed cylinder two, and compresses the return spring three and the damper. At the same time, it also causes the connecting rod to deflect, causing the two rings to move towards each other on the outer surface of the fixed cylinder, which in turn compresses the return spring two. This converts the up-and-down vibration into the horizontal motion of the rings. Compared with the rigid support absorbing vibration in the comparative document, the vibration energy is absorbed in stages through the elastic potential energy of the return spring two and three and the damper, resulting in a significant improvement in vibration reduction efficiency.

[0033] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0034] This application discloses a support bracket for a gearbox.

[0035] Reference Figure 1 , Figure 2A gearbox support includes a support base 1 and a gearbox body 4. An automatic lifting device can be installed at the bottom of the support base 1. The inner wall of the support base 1 is slidably connected to a second support base 2. A groove is provided inside the second support base 2 for placing the gearbox body 4. The groove of the second support base 2 is slidably connected to a clamping frame 5, which clamps the gearbox body 4. Several clamping mechanisms are provided between the second support base 2 and the clamping frame 5, which elastically clamp the gearbox body 4. A baffle 3 is fixedly connected between the second support base 2 and the clamping frame 5, and the baffle 3 is located above the clamping mechanisms to protect them from external impurities, dust, etc. The baffle 3 and the clamping frame 5 are both made of high-damping synthetic rubber, such as nitrile rubber or hydrogenated nitrile rubber, with a Shore hardness range of 40-70A, ensuring sufficient clamping force while avoiding stress concentration or scratches on the surface of the gearbox body 4 due to excessive hardness.

[0036] When the gearbox body 4 is placed inside the clamping frame 5 during use, the clamping frame 5 will be squeezed by the outer surface of the gearbox body 4, thereby deforming. This will cause the baffle 3, which is fixedly connected to the clamping frame 5, to deform as well, and the gearbox body 4 will be clamped by the reaction force provided by the clamping mechanism.

[0037] like Figure 1 As shown, the gearbox body 4 displays part of its structure.

[0038] Reference Figure 2 , Figure 3 The clamping mechanism includes several fixed seats 61, which are fixedly connected to the inner wall of the support seat 2. A rotating block 62 is rotatably connected to one side of the fixed seat 61. The rotating block 62 is located near the clamping frame 5. The side of the rotating block 62 away from the fixed seat 61 is fixedly connected to the fixed frame 63. The inner wall of the fixed frame 63 is slidably connected to the moving column 65. A limiting groove can be opened inside the fixed frame 63. A limiting ring can be fixed on the outer surface of the moving column 65. When the moving column 65 moves to its maximum extent, the limiting ring engages with the limiting groove to prevent the moving column 65 from detaching from the fixed frame 63. A rotating block 62 is fixedly connected to one side of the moving column 65. 66. Rotating block 2 66 is located on the side of moving column 1 65 away from fixed frame 1 63. A return spring 1 64 is fixedly connected to the side of rotating block 2 66 near moving column 1 65. The side of return spring 1 64 away from rotating block 2 66 is fixedly connected to the side of rotating block 1 62 near fixed frame 1 63. The return spring 1 64 is sleeved on the outer surface of fixed frame 1 63 and moving column 1 65. Fixed frame 1 63, return spring 1 64 and moving column 1 65 cooperate with each other to realize adaptive clamping of gearbox body 4. The side of rotating block 2 66 away from moving column 1 65 is rotatably connected to fixed seat 2 67. Fixed seat 2 67 is fixedly connected to the outer surface of clamping frame 5.

[0039] When the gearbox body 4 is clamped by the clamping frame 5, the clamping frame 5 can adaptively adjust with the outer surface of the gearbox body 4. When the clamping frame 5 expands outward, it will drive the fixed seat 2 67 and the rotating block 2 66 to move outward, thereby pushing the moving column 1 65 into the interior of the fixed frame 1 63, and simultaneously squeezing the return spring 1 64, causing the return spring 1 64 to be compressed. The reaction force provided by the return spring 1 64 makes the clamping frame 5 tightly adhere to the outer surface of the gearbox body 4.

[0040] Reference Figure 1 , Figure 4 Several connecting mechanisms are provided between support base 1 and support base 2. These connecting mechanisms include several fixed plates 71 fixedly connected to the bottom surface of support base 2. The fixed plates 71 are n-shaped. The center of the inner wall of the fixed plate 71 is fixedly connected to a fixed cylinder 72, and there is a certain gap between the fixed cylinder 72 and the top surface of the fixed plate 71. The outer surface of the fixed cylinder 72 is slidably connected to two rings 74, which are symmetrical. The opposing surfaces of the two rings 74 are fixedly connected to a return spring 75, which is sleeved on the outer surface of the fixed cylinder 72. The lower part of the arc surface of each of the two rings 74 is rotatably connected to a connecting rod 76. One side of the connecting rod 76 is rotatably connected to a fixed base 77, which is located away from the rings 74. The top of support base 1... The surface of the fixed plate 73 is fixedly connected to several fixed plates 73. The top surface of the fixed plate 73 is fixedly connected to the fixed base 77. The two sides of the fixed plate 73 and the fixed plate 71 are fixedly connected to the dampers 711, and the two dampers 711 are symmetrical to each other. The two sides of the top surface of the fixed plate 73 are fixedly connected to the interactive fixed cylinder 78, and the two fixed cylinders 78 are symmetrical to each other. The inner wall of the fixed cylinder 78 is slidably connected to the movable column 79. The side of the movable column 79 away from the fixed cylinder 78 is fixedly connected to the bottom surface of the fixed plate 71. The two sides of the bottom surface of the fixed plate 71 are fixedly connected to the return spring 710. The side of the return spring 710 away from the fixed plate 71 is fixedly connected to the top surface of the fixed plate 73. The return spring 710 is sleeved on the outer surface of the fixed cylinder 78 and the movable column 79.

[0041] During use, since support seat 2 is slidably connected inside support seat 1, when the rotating shaft inside the gearbox body 4 generates radial vibration due to rotation, it will cause the gearbox body 4 and support seat 2 to vibrate up and down as a whole, which in turn will cause the fixing plate 71 to vibrate up and down. The up and down vibration of the fixing plate 71 will compress the return spring 710 and the damper 711 for vibration reduction. When the fixing plate 71 moves downward, it will drive the fixing cylinder 72 to move downward, which in turn will drive the two rings 74 to move downward, thereby driving the connecting rod 76. The cylinder deflects, thereby squeezing the second return spring 75 to slide towards the middle of the ring 74. Conversely, when the fixed cylinder 72 moves upward, it drives the two rings 74 to move upward, thereby driving the connecting rod 76 to deflect, which in turn squeezes the second return spring 75 to slide towards both ends of the ring 74. The rotation of the connecting rod 76 converts the impact into the horizontal movement of the ring 74, thereby squeezing or stretching the second return spring 75 to consume energy. It also works in conjunction with the third return spring 710 and the damper 711 to reduce vibration in the gearbox body 4.

[0042] Among them, the model of damper 711 is Taylor Devices damper;

[0043] In this device, the return springs 64, 75, and 710 all use the alloy spring calculation formula: F = kx, where F is the external force on the spring (unit: N / m), k is the spring constant (unit: N / m), and x is the spring deformation (unit: m). This formula is used to calculate the elastic force of the alloy springs so that they can be used in this device. All three return springs (64, 75, and 710) are stainless steel alloys such as SUS304, which have good elastic recovery properties.

[0044] The ring 74 is made of SUS304 stainless steel, and the connecting rod 76 is made of high-strength aluminum alloy, ensuring a lightweight structure with strong load-bearing capacity.

[0045] The implementation principle of a gearbox support bracket according to an embodiment of this application is as follows:

[0046] When in use, the gearbox body 4 is placed inside the clamping frame 5. The clamping frame 5 will be squeezed by the outer surface of the gearbox body 4, thus deforming. This will cause the baffle 3, which is fixedly connected to the clamping frame 5, to deform as well. When the clamping frame 5 expands outward, it will drive the fixed seat 2 67 and the rotating block 2 66 to move outward, thereby pushing the moving column 1 65 into the interior of the fixed frame 1 63 and simultaneously squeezing the return spring 1 64, compressing the return spring 1 64. The reaction force provided by the return spring 1 64 makes the clamping frame 5 stick tightly to the outer surface of the gearbox body 4.

[0047] When the rotating shaft inside the gearbox body 4 generates radial vibration due to rotation, it will cause the gearbox body 4 and the support seat 2 to vibrate up and down as a whole, which in turn will cause the fixed plate 71 to vibrate up and down. The up and down vibration of the fixed plate 71 will squeeze the return spring 710 and the damper 711 to reduce vibration. At the same time, when the fixed plate 71 moves up and down, it will drive the fixed cylinder 72 and the two rings 74 to move together, thereby causing the connecting rod 76 to deflect, which will squeeze the return spring 75 to slide towards the middle or both ends of the ring 74. The impact is converted into the horizontal movement of the ring 74 by the rotation of the connecting rod 76, which will squeeze or stretch the return spring 75 to consume energy, and cooperate with the return spring 710 and the damper 711 to reduce vibration of the gearbox body 4.

[0048] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
