Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing housing technology, specifically a shaft base with a protective structure. Background Technology
[0002] Slewing bearing housings are large and extra-large bearing housings with special construction that can accept comprehensive loads. They are characterized by compact construction, sensitive rotation, and convenient installation and maintenance. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is what is commonly referred to as the bearing housing.
[0003] Some devices on the market typically use a knob, a clamp, a guide rod, and a threaded sleeve. Turning the knob moves the threaded sleeve, and through the threaded engagement structure between the threaded sleeve and the threaded through-hole on the clamp, the threaded sleeve moves the clamp horizontally. This not only enables the clamp to adjust the axial clamping of the outer ring of different bearing models, but also effectively prevents the outer ring of the bearing from shifting axially due to the clamping of the clamp.
[0004] However, the process of disassembling and using the above-mentioned equipment for a long time will cause loosening between the shaft and the mounting base, and slight shaking will occur when the shaft rotates, which will make the mechanical operation unstable. In view of this, we propose a shaft base with a protective structure. Utility Model Content
[0005] The purpose of this invention is to provide a shaft base with a protective structure to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a shaft base with a protective structure, including a mounting base, a mounting component fixedly connected to the upper surface of the mounting base, a fixing component provided on the upper surface of the mounting component, a bolt provided on the upper surface of the fixing component, a bearing snapped into the fixing component, and a stabilizing component provided on the side of the fixing component, the stabilizing component including:
[0007] A movable component is rotatably connected to the side of a fixed component. The side of the movable component has a mounting groove, and a rotating component is rotatably connected to the inner wall of the mounting groove.
[0008] A movable block is threadedly connected to the outer surface of the rotating component, and a pressing component is hinged to the side of the movable block.
[0009] Preferably, the side of the pressing member is arc-shaped and the arc-shaped surface is provided with ball bearings. The center of the pressing member corresponds to the center of the movable block, which allows the pressing member to fit better when it comes into contact with the outer surface of the shaft.
[0010] Preferably, the size of the movable block is adapted to the size of the movable part, and the movable block is disposed inside the mounting slot, which allows the movable block to move inside the mounting slot.
[0011] Preferably, the rotating component is composed of a threaded rod fixedly connected to the side of the rotating block, and the side of the mounting component is also provided with a movable component, a mounting groove, a rotating component, a movable block, and a pressing component, which makes the shaft more stable when rotating.
[0012] Preferably, the mounting component has an auxiliary component inside, the auxiliary component including a lower protrusion, the lower protrusion being fixedly connected to the inner wall of the mounting component, and an upper protrusion being fixedly connected to the inner wall of the mounting component.
[0013] Preferably, the size of the upper protrusion is adapted to the size of the fixing member, and the upper protrusion is evenly distributed in a circumferential array on the inner wall of the fixing member.
[0014] Preferably, the lower protrusion and the upper protrusion are arranged in an arc shape, and the arc-shaped surfaces of the lower protrusion and the upper protrusion are provided with semi-circular grooves.
[0015] Compared with the prior art, the present invention provides a shaft base with a protective structure, which has the following beneficial effects:
[0016] 1. This shaft base with a protective structure, in order to make the equipment operate more stably, places the bearing inside the mounting component, merges the fixing component with the mounting component, and uses bolts to limit it. After the shaft is installed inside the bearing, rotate the movable component so that the arc-shaped surface of the pressing block corresponds to the outer surface of the shaft. Then rotate the rotating component so that the movable block extends out of the movable component and the arc-shaped surface of the pressing block contacts the outer surface of the shaft. In this way, when the shaft rotates, the balls set on the arc-shaped surface of the pressing block will rotate with the shaft, thereby making the shaft operate more stably.
[0017] 2. This shaft base with a protective structure, in order to ensure stable operation of the bearing, when the bearing is placed inside the mounting component, the outer surface of the bearing will contact the arc-shaped surface of the lower protrusion. After the fixing component and the mounting component are combined, the upper protrusion will contact the outer surface of the bearing. The lower and upper protrusions are arc-shaped, and the arc-shaped surfaces are provided with arc-shaped grooves. This increases the friction between the bearing and the mounting and fixing components when the bearing rotates, making the bearing more stable during operation. Attached Figure Description

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a shaft base with a protective structure, including a mounting base 1. A mounting component 2 is fixedly connected to the upper surface of the mounting base 1. The side of the mounting component 2 is also provided with a movable component 601, a mounting groove 602, a rotating component 603, a movable block 604, and a pressing component 605, which makes the shaft more stable when rotating. A fixing component 3 is provided on the upper surface of the mounting component 2, and a bolt 4 is provided on the upper surface of the fixing component 3. A bearing 5 is snapped into the inside of the fixing component 3. A stabilizing component 6 is provided on the side of the fixing component 3. The stabilizing component 6 includes a movable component 601, a mounting groove 602, a rotating component 603, a movable block 604, and a pressing component 605.
[0024] In this embodiment of the present invention, the movable member 601 is rotatably connected to the side of the fixed member 3. The side of the movable member 601 is provided with a mounting groove 602. The inner wall of the mounting groove 602 is rotatably connected to a rotating member 603. The rotating member 603 is composed of a rotating block with a threaded rod fixedly connected to its side. The movable block 604 is threadedly connected to the outer surface of the rotating member 603. The size of the movable block 604 is adapted to the size of the movable member 601. The movable block 604 is disposed inside the mounting groove 602, which allows the movable block 604 to move inside the mounting groove 602. The side of the movable block 604 is hinged to a pressing member 605. The side of the pressing member 605 is arc-shaped, and the arc surface is provided with balls. The center of the pressing member 605 corresponds to the center of the movable block 604, which allows the pressing member 605 to fit better when it contacts the outer surface of the shaft.
[0025] Meanwhile, an auxiliary component 7 is provided inside the mounting component 2. The auxiliary component 7 includes a lower protrusion 701, which is fixedly connected to the inner wall of the mounting component 2. The lower protrusion 701 and the upper protrusion 702 are arranged in an arc shape, and the arc surfaces of the lower protrusion 701 and the upper protrusion 702 are provided with semi-circular grooves. The upper protrusion 702 is fixedly connected to the inner wall of the fixing component 3. The size of the upper protrusion 702 is adapted to the size of the fixing component 3. The upper protrusions 702 are evenly distributed in a circumferential array on the inner wall of the fixing component 3. In this way, when the bearing 5 is placed inside the mounting component 2, the outer surface of the bearing 5 will contact the arc surface of the lower protrusion 701. After the fixing component 3 is combined with the mounting component 2, the upper protrusion 702 will contact the outer surface of the bearing 5. The lower protrusion 701 and the upper protrusion 702 are arranged in an arc shape, and the arc surfaces are provided with arc grooves. This increases the friction between the bearing 5 and the mounting component 2 and the fixing component 3 when the bearing 5 rotates, making the bearing 5 more stable when it operates.
[0026] In this invention, during use, the bearing 5 is placed inside the mounting part 2, and the fixing part 3 is merged with the mounting part 2 and secured with bolts 4. After the shaft is installed inside the bearing 5, the movable part 601 is rotated so that the arc-shaped surface of the pressing part 605 corresponds to the outer surface of the shaft. Then, the rotating part 603 is rotated so that the movable block 604 extends out of the movable part 601, allowing the arc-shaped surface of the pressing part 605 to contact the outer surface of the shaft. In this way, when the shaft rotates, the balls set on the arc-shaped surface of the pressing part 605 will rotate with the shaft, thereby making the shaft operate more stably.
[0027] Furthermore, when the bearing 5 is placed inside the mounting part 2, the outer surface of the bearing 5 will contact the arc-shaped surface of the lower protrusion 701. After the fixing part 3 is combined with the mounting part 2, the upper protrusion 702 will contact the outer surface of the bearing 5. The lower protrusion 701 and the upper protrusion 702 are arc-shaped, and the arc-shaped surface is provided with an arc-shaped groove. This increases the friction between the bearing 5 and the mounting part 2 and the fixing part 3 when the bearing 5 rotates, making the bearing 5 more stable when it operates.
[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
