Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearing manufacturing, in particular to a vertical rotary bearing. Background Art
[0002] Vertical slewing bearings are specially designed bearings, usually used in applications where the vertical axis rotates. The structure of the vertical slewing bearing includes an inner ring, an outer ring, rolling elements, a cage, a seal cover and a lubrication system. This bearing design allows it to withstand gravity and other vertical loads in the vertical direction while maintaining the smoothness of the rotational motion. Its special structure and function make it suitable for specific engineering and industrial applications.
[0003] However, in order to improve the heat dissipation effect of the existing vertical rotating bearing, a split protection frame is required, and the split protection frame is usually connected by a snap-fit connection. During high-speed rotation, the split protection frame will deviate from its original position due to the action of centrifugal force and inertia force, thereby affecting the accurate fixation of the relative position of the rolling element by the protection frame. Utility Model Content
[0004] 1. Technical issues to be solved
[0005] In view of the deficiencies in the prior art, the utility model provides a vertical rotating bearing, which can solve the problem that the split protective frame of the existing vertical rotating bearing will deviate from its original position during high-speed rotation due to the action of centrifugal force and inertia force, thereby affecting the accurate fixation of the protective frame to the relative position of the rolling body. The split protective frame can be automatically locked and the split protective frame can be quickly disassembled through simple operation, which facilitates the rapid maintenance of the bearing without damaging the split protective frame.
[0006] (II) Technical solution
[0007] To achieve the above object, the utility model provides the following technical solutions: a vertical rotary bearing, comprising a lower protective frame, the upper surface of the lower protective frame is fixedly connected with a docking column, a sliding component is arranged inside the docking column, a notch is opened on the outer surface of the docking column, the sliding component comprises a connecting spring and a slider, and a self-locking component is arranged inside the slider;
[0008] The self-locking component includes a positioning spring, a clamping block and a shifting rod, one end of the positioning spring is fixedly connected to the slider, the other end of the positioning spring is interconnected with the clamping block, and the outer surface of the clamping block is interconnected with the shifting rod.
[0009] Through the above technical solution, the position of the slider is adjusted by utilizing the gravity and thrust exerted on it, so that the slider drives the self-locking component to adjust the position, and the upper protection frame and the lower protection frame are locked by the self-locking component, thereby preventing the position of the protection frame relative to the rolling body from changing during rotation.
[0010] Furthermore, a docking hole and a card slot are provided inside the upper protective frame, and the docking hole and the card slot are connected to each other. An upper protective frame is arranged above the lower protective frame, and a rolling body is arranged between the upper and lower protective frames. An inner ring is arranged on the inner side of the rolling body, and an outer ring is arranged on the outer side of the rolling body. Sealing covers are respectively arranged on the upper and lower sides of the upper and lower protective frames.
[0011] Through the above technical solution, the upper protection frame and the lower protection frame are respectively located on both sides of the rolling body, and together fix the relative positions between the rolling bodies to prevent the rolling bodies from colliding with each other.
[0012] Furthermore, the docking holes are centrally symmetrically distributed about the center of the upper protective frame, and the docking posts are centrally symmetrically distributed about the center of the lower protective frame, and the docking posts correspond to the docking holes one by one.
[0013] Through the above technical solution, the docking column and the docking hole are snap-connected to allow the upper protection frame to dock with the lower protection frame quickly, and multiple rolling bodies are quickly separated during the docking process of the upper protection frame and the lower protection frame.
[0014] Furthermore, an adjustment hole is provided on the upper surface of the docking column, and the lever and the clamping block are in an "L"-shaped structure when viewed from the side, and the centers of the lever and the adjustment hole are located on the same vertical line.
[0015] Through the above technical solution, the lever is pushed to separate the block and the slot, and the slider is caused to slide toward the inside of the docking column under the action of gravity, thereby quickly releasing the mutual locking between the upper protective frame and the lower protective frame, making it convenient to quickly disassemble the upper protective frame and the lower protective frame, thereby improving the convenience of bearing inspection.
[0016] Furthermore, one end of the connecting spring is welded to the docking column, and the other end of the connecting spring is interconnected with the slider. The slider forms a telescopic structure inside the docking column through the connecting spring, and the height of the slider is smaller than the height of the docking column.
[0017] Through the above technical solution, the bearing is flipped so that the lower protective frame is located at the top and the upper protective frame is located at the bottom. At this time, the slider will slide inside the docking column under the action of gravity and the thrust of the connecting spring. By adjusting the position of the slider, the subsequent need for the upper protective frame and the lower protective frame to be locked to each other can be met, thereby improving the convenience of locking the upper protective frame and the lower protective frame to each other.
[0018] Furthermore, the connecting spring and the positioning spring are both made of chrome-silicon alloy steel.
[0019] Through the above technical solution, during the high-speed rotation of the bearing, the spring inside it will be subjected to greater inertia and centrifugal force, and chromium-silicon alloy steel has a higher elastic limit and fatigue life. Its application in high-speed rotating bearings can effectively prevent deformation or fatigue failure.
[0020] Furthermore, the clamping block forms a telescopic structure inside the slider through a positioning spring, the clamping block is symmetrically distributed about the longitudinal center line of the slider, and the diameter of the clamping block is smaller than the diameter of the clamping slot.
[0021] Through the above technical solution, when the block inside the slider is aligned with the slot opened inside the docking column, the positioning spring pushes the block to engage with the slot opened inside the upper protective frame, so that the upper protective frame and the lower protective frame are locked with each other, thereby preventing the position of the split protective frame from shifting during high-speed rotation, which is beneficial to ensure the accurate fixation of the relative position of the protective frame to the rolling body.
[0022] Compared with the prior art, the utility model provides a vertical rotary bearing, which has the following beneficial effects:
[0023] When the upper and lower protective frames are in a state of being locked together, the upper and lower protective frames can be quickly connected to each other by engaging the docking post and the docking hole. When the bearing is turned 180° so that the lower protective frame is located at the top and the upper protective frame is located at the bottom, the slider is subjected to the action of gravity and the thrust of the connecting spring to slide inside the docking post. When the block inside the slider is aligned with the notch opened inside the docking post, the positioning spring pushes the block to engage with the slot opened inside the upper protective frame for connection. At this time, the upper and lower protective frames are locked with each other, thereby preventing the position of the split protective frame from shifting during high-speed rotation. The bearing is turned 180° again, and after the lever is pushed to separate the block and the slot from each other, the slider is subjected to the action of gravity to slide toward the inside of the docking post, thereby quickly releasing the mutual locking between the upper and lower protective frames, facilitating the quick disassembly of the upper and lower protective frames, and improving the convenience of bearing inspection.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0034] See also Figure 4-Figure 7 The utility model provides a technical solution: a vertical rotary bearing, including a lower protective frame 4, a docking column 9 is fixedly connected to the upper surface of the lower protective frame 4, a sliding component is arranged inside the docking column 9, a notch 15 is opened on the outer surface of the docking column 9, the sliding component includes a connecting spring 10 and a slider 11, and a self-locking component is arranged inside the slider 11;
[0035] See also Figure 7-Figure 8 The self-locking component includes a positioning spring 12, a block 13 and a lever 14, one end of the positioning spring 12 is fixedly connected to the slider 11, the other end of the positioning spring 12 is interconnected with the block 13, and the outer surface of the block 13 is interconnected with the lever 14.
[0036] The principle of being able to quickly and automatically lock the upper protective frame 3 and the lower protective frame 4 is as follows: the lower protective frame 4 is installed below the bearing rolling element 2, and then the upper protective frame 3 is installed above the bearing rolling element 2, and it is ensured that the docking column 9 connected to the lower protective frame 4 passes through the docking hole 7 opened inside the upper protective frame 3, and then the bearing is flipped 180° so that the lower protective frame 4 is located at the top and the upper protective frame 3 is located at the bottom. At this time, the slider 11 is subjected to the action of gravity and the thrust of the connecting spring 10 and slides inside the docking column 9. When the block 13 inside the slider 11 is aligned with the notch 15 opened inside the docking column 9, the positioning spring 12 pushes the block 13 through the notch 15, so that the block 13 is engaged and connected with the slot 8 opened inside the upper protective frame 3. At this time, the upper protective frame 3 is locked with the lower protective frame 4, thereby preventing the position of the split protective frame from shifting during high-speed rotation.
[0037] See also Figure 1-Figure 4 A docking hole 7 and a card slot 8 are provided inside the upper protective frame 3, and the docking hole 7 and the card slot 8 are connected to each other. The upper protective frame 3 is arranged above the lower protective frame 4, and a rolling body 2 is arranged between the upper protective frame 3 and the lower protective frame 4. An inner ring 1 is arranged on the inner side of the rolling body 2, and an outer ring 5 is arranged on the outer side of the rolling body 2. Sealing covers 6 are respectively provided on the upper and lower sides of the upper protective frame 3 and the lower protective frame 4. The docking holes 7 are centrally symmetrically distributed about the center of the upper protective frame 3, and the docking columns 9 are centrally symmetrically distributed about the center of the lower protective frame 4, and the docking columns 9 correspond to the docking holes 7 one by one.
[0038] It should be noted that: the upper protection frame 3 and the lower protection frame 4 can be quickly docked through the snap connection between the docking column 9 and the docking hole 7, and the multiple rolling bodies 2 can be quickly separated during the docking process to fix the relative positions between the rolling bodies 2 to prevent the rolling bodies 2 from colliding with each other.
[0039] See also Figure 4-Figure 8 An adjustment hole 16 is provided on the upper surface of the docking column 9, and the lever 14 and the block 13 are in an "L"-shaped structure when viewed from the side, and the centers of the lever 14 and the adjustment hole 16 are located on the same vertical line.
[0040] The principle of being able to quickly disassemble the upper protective frame 3 and the lower protective frame 4 is as follows: flip the bearing so that the upper protective frame 3 is located at the top and the lower protective frame 4 is located at the bottom, and the lever 14 is pushed to separate the block 13 and the slot 8 from each other, and the slider 11 slides toward the inside of the docking column 9 under the action of gravity, thereby quickly releasing the mutual locking between the upper protective frame 3 and the lower protective frame 4, making it convenient to quickly disassemble the upper protective frame 3 and the lower protective frame 4, and improving the convenience of bearing maintenance.
[0041] See also Figure 4-Figure 8One end of the connecting spring 10 is welded to the docking column 9, and the other end of the connecting spring 10 is connected to the slider 11. The slider 11 forms a telescopic structure inside the docking column 9 through the connecting spring 10. The height of the slider 11 is less than the height of the docking column 9. The block 13 forms a telescopic structure inside the slider 11 through the positioning spring 12. The block 13 is symmetrically distributed about the longitudinal center line of the slider 11, and the diameter of the block 13 is less than the diameter of the slot 8.
[0042] The function of the slider 11 is to use the gravity on the slider 11 and the thrust of the connecting spring 10 to adjust the position of the slider 11. The slider 11 drives the self-locking component to adjust the position. The self-locking component meets the subsequent requirement of automatic mutual locking of the upper protection frame 3 and the lower protection frame 4, which is conducive to ensuring the accurate fixation of the relative position of the protection frame to the rolling body 2.
[0043] See also Figure 7-Figure 8 The materials of the connecting spring 10 and the positioning spring 12 are both chrome-silicon alloy steel.
[0044] It is worth mentioning that the connecting spring 10 and the positioning spring 12 are made of chrome-silicon alloy steel, which has a high elastic limit and fatigue life. The application of chrome-silicon alloy steel in high-speed rotating bearings can effectively prevent deformation or fatigue failure.
