[0001] This utility model relates to the technical field of bearing disassembly tools, specifically a tool for disassembling the outer steel ring of a motorcycle steering bearing. Background Technology

[0002] With the development of motorcycle repair tools, various bearing disassembly tools have been widely used. However, these products still have some problems in actual use. For example, most bearing disassembly tools on the market are used for different scenarios such as deep holes, blind holes or shaft ends, but there is still a lack of special disassembly tools for the specific structure of the outer steel ring of the motorcycle steering bearing. This has led to problems such as inconvenience in operation, low efficiency and damage to the frame in some scenarios.

[0003] Traditional bearing disassembly tools currently on the market are insufficient to effectively meet the demands for efficient and safe disassembly in the specific application scenario of motorcycle steering bearing outer steel rings. Therefore, this utility model provides a disassembly tool specifically designed for motorcycle steering bearing outer steel rings to overcome these shortcomings and provide a more convenient, reliable, and adaptable solution for confined spaces. To this end, we provide a motorcycle steering bearing outer steel ring disassembly tool to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a tool for disassembling the outer steel ring of a motorcycle steering bearing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tool for disassembling the outer steel ring of a motorcycle steering bearing, comprising a clamping mechanism and a disassembly mechanism. The clamping mechanism includes a slotted crossbeam and an adjusting screw with a rotatable portion. The adjusting screw is threadedly connected to the inside of the slotted crossbeam. A T-slot triangular retainer is provided on one side of the slotted crossbeam. The T-slot triangular retainer has a threaded hole in the middle and T-slots on both sides. A limit screw is provided in the threaded hole of the T-slot triangular retainer. The limit screw is fixedly connected to the rotatable portion of the adjusting screw. Two two-stage hooks are provided on both sides of the T-slot triangular retainer. The two-stage hooks are slidably connected to the sides of the T-slot triangular retainer. The U-shaped groove ends of the two-stage hooks are slidably connected to both ends of the slotted crossbeam. The disassembly mechanism includes a pull rod. The pull rod is threadedly connected to the other end of the adjusting screw. A slidable counter-hammer is sleeved on the outer surface of the pull rod. A striker is fixedly connected to the other end of the pull rod.

[0006] Furthermore, the slotted crossbeam has straight slots at both ends, and a headless screw shaft and a rolling steel sleeve are provided inside the straight slots. The rolling steel sleeve is fitted onto the outer surface of the headless screw shaft. The headless screw shaft is fixedly connected to the inner wall of the U-shaped groove of the two-stage hook. The two-stage hook is slidably connected to both ends of the slotted crossbeam through the headless screw shaft and the rolling steel sleeve.

[0007] Furthermore, the two-stage pull hook is provided with countersunk screws, bushings, and square sliders. The square sliders are installed on the two-stage pull hooks by countersunk screws and bushings, and the square sliders are adapted to the T-slots on the side of the T-slot triangular retainer. The two-stage pull hooks are slidably connected to the side of the T-slot triangular retainer by the square sliders.

[0008] Furthermore, a grip is fixedly connected to the outer surface of the impact seat, and the outer surface of the grip is provided with anti-slip texture.

[0009] Furthermore, the two-stage hook adopts a double barb design, including a small barb at the head and a large barb in the middle.

[0010] Furthermore, both the slotted crossbeam and the two-stage hook are made of high-strength chromium-molybdenum steel.

[0011] Furthermore, the outer surfaces of the slotted crossbeam, the two-stage hooks, and the tie rod are all chrome-plated.

[0012] Compared with existing technologies, this motorcycle steering bearing outer steel ring disassembly tool has the following advantages:

[0013] This invention improves the adaptability of the device to different bearing ring sizes by setting a double-barbed two-stage pull hook. By rotating the adjusting screw, the two-stage pull hook can be expanded by the T-slot triangular retainer to act on the target bearing ring. At the same time, through the disassembly mechanism, when the pull rod on the counter-hammer slides and hits the impact seat, it can generate a pulling force on the adjusting screw, thereby pulling the clamping component to achieve the purpose of disassembling the bearing ring. The T-slot on the T-slot triangular retainer can maintain a tight sliding connection with the two-stage pull hook and play a supporting role to ensure the overall stability of the device. At the same time, the built-in disassembly method can prevent the two-stage pull hook from scratching the outer surface of the motorcycle bearing seat, improving the safety of the device during use.

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] See Figure 1 -

[0023] Figure 5 This embodiment proposes a tool for removing the outer steel ring of a motorcycle steering bearing, including a clamping mechanism and a disassembly mechanism.

[0024] The clamping mechanism includes a slotted crossbeam 11 and an adjusting screw 14 with a rotatable part.

[0025] See Figure 2 One end of the slotted crossbeam 11 is a rotatable part, and the other end is a columnar structure with internal threads.

[0026] The adjusting screw 14 is threadedly connected to the inside of the slotted crossbeam 11. A T-slot triangular retainer 12 is provided on one side of the slotted crossbeam 11. The T-slot triangular retainer 12 has a threaded hole in the middle and T-slots on both sides. A limit screw 121 is provided in the threaded hole of the T-slot triangular retainer 12. The limit screw 121 is fixedly connected to the rotatable part of the adjusting screw 14.

[0027] By setting the limit screw 121, the adjusting screw 14 can not move axially but can rotate when connected to the T-slot triangular retainer 12. If the adjusting screw 14 is rotated, the slotted beam 11 and the T-slot triangular retainer 12 will move away from each other.

[0028] The T-slot triangular retainer 12 has two two-stage hooks 13 on both sides. The two-stage hooks 13 are slidably connected to the side of the T-slot triangular retainer 12, and the U-shaped groove ends of the two-stage hooks 13 are slidably connected to both ends of the slotted crossbeam 11.

[0029] The two-stage hook 13 adopts a double barb design, including a small barb at the head and a large barb in the middle.

[0030] Both the slotted crossbeam 11 and the two-stage hook 13 are made of high-strength chromium-molybdenum steel, which gives the slotted crossbeam 11 and the two-stage hook 13 high wear resistance and impact resistance.

[0031] The slotted crossbeam 11 has straight slots at both ends, and a headless screw shaft 111 and a rolling steel sleeve 112 are provided inside the straight slots. The rolling steel sleeve 112 is sleeved on the outer surface of the headless screw shaft 111. The headless screw shaft 111 is fixedly connected to the inner wall of the U-shaped groove of the two-stage hook 13. The two-stage hook 13 is slidably connected to both ends of the slotted crossbeam 11 through the headless screw shaft 111 and the rolling steel sleeve 112.

[0032] The two-stage pull hook 13 is provided with a countersunk screw 131, a bushing 132, and a square slider 133. The square slider 133 is installed on the two-stage pull hook 13 through the countersunk screw 131 and the bushing 132, and the square slider 133 is adapted to the T-slot on the side of the T-slot triangular retainer 12. The two-stage pull hook 13 is slidably connected to the side of the T-slot triangular retainer 12 through the square slider 133.

[0033] When the slotted crossbeam 11 is held and the adjusting screw 14 is rotated, the T-slot triangular retainer 12 will move away from the slotted crossbeam 11. At the same time, due to the restriction of the headless screw shaft 111 and the rolling steel sleeve 112, the two-stage hooks 13 cannot move in the same direction as the T-slot triangular retainer 12. The T-slot triangular retainer 12 will push the two-stage hooks 13 outward. Due to the restriction of the square slider 133, the two-stage hooks 13 will slide with the T-slot triangular retainer 12. Based on the triangular structure of the T-slot triangular retainer 12, the two two-stage hooks 13 will move away from each other, so as to achieve the purpose of using appropriate barbs to get into the gap between the bearing steel ring and the bearing base.

[0034] The disassembly mechanism includes a pull rod 22, which is threaded to the other end of the adjusting screw 14. A slidable counter-hammer 21 is sleeved on the outer surface of the pull rod 22, and a striker 23 is fixedly connected to the other end of the pull rod 22.

[0035] When the counter-hammer 21 slides and impacts the impact seat 23 on the pull rod 22, the impact seat 23 will instantly pull the adjusting screw 14 based on its motion inertia, thereby achieving the overall pulling of the clamping mechanism. At the same time, based on the barbs of the two-stage pull hook 13 being inserted into the gap between the bearing steel ring and the bearing base, after multiple pulls, the bearing steel ring can be pulled out from the bearing base, thus achieving the purpose of disassembling the bearing steel ring.

[0036] The outer surface of the impact seat 23 is fixedly connected to the handle 24, and the outer surface of the handle 24 is provided with anti-slip texture.

[0037] The outer surfaces of the slotted crossbeam 11, the two-stage hooks 13, and the tie rod 22 are all chrome-plated, which makes the slotted crossbeam 11, the two-stage hooks 13, and the tie rod 22 more corrosion-resistant and wear-resistant.

[0038] Working principle: First, place the two-stage hooks 13 in the clamping mechanism into the bearing base of the motorcycle steering wheel pipe, and hold the slotted crossbeam 11. Rotate the adjusting screw 14 to move the T-slot triangular retainer 12 and push the two-stage hooks 13 on both sides. The two-stage hooks 13 slide on both sides of the T-slot triangular retainer 12. During the sliding of the two-stage hooks 13, the barbs on the two-stage hooks 13 will get stuck in the narrow gap between the bearing steel ring and the bearing base. Due to the support of the T-slot triangular retainer 12, the bearing steel ring will be locked firmly by the barbs. Screw the pull rod 22 into the screw hole at the end of the adjusting screw 14, and hold the counter-hammer 21 to strike the striker 23 with force. Repeat several times to remove the bearing steel ring, thus disassembling the motorcycle bearing steel ring.
