The tool is simple and quick to operate, improving the efficiency of bearing disassembly and assembly operations. As an integrated tool, it can be moved as a whole, enhancing its ease of use and storage.

The knob and connecting ring structure synchronously transmit and control multiple support frames, improving operational convenience and ensuring synchronized spacing adjustment to avoid deviations. This allows it to adapt to the disassembly and assembly of bearings of various sizes, expanding the tool's applicability. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Bearings are essential components in mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during movement, and ensure rotational accuracy. Based on the frictional properties of the moving elements, bearings can be divided into two main categories: rolling bearings and sliding bearings. Rolling bearings are standardized and serialized, but compared to sliding bearings, they have larger radial dimensions, higher vibration and noise levels, and are also more expensive.

[0024] Bearing assembly and disassembly tools refer to a series of tools and equipment used for installing and disassembling bearings. These tools are used to efficiently and safely disassemble and install bearings, solve problems in the bearing disassembly and installation process, ensure the smooth completion of the operation, reduce damage to bearings and equipment, reduce manual operation time and physical labor consumption, and use professional tools for bearing assembly and disassembly to ensure the safety of operators and reduce the possibility of accidents.

[0025] In the era of Industry 4.0, equipment maintenance efficiency and precision have become core elements of competitiveness in the manufacturing industry. Portable bearing assembly and disassembly tools, with their modular design, intelligent control, and adaptability to various scenarios, are reshaping traditional equipment maintenance models. These tools not only solve problems such as space constraints and low efficiency in the assembly and disassembly of large bearings, but also achieve a dual breakthrough in equipment protection and cost optimization through technological innovation.

[0026] Portable tools, through modular design, integrate tools such as pullers, mounting rings, and impact sleeves, achieving "multi-purpose use in one box." For example, a hydraulic puller combined with the oil injection method can complete the disassembly of large bearings within 10 minutes, improving efficiency by 70% compared to the traditional hammering method. Portable bearing disassembly and assembly tools, through modular design, precise force control, and scene adaptability optimization, solve the pain points of traditional tools such as low efficiency, high damage, and environmental limitations. Their technological iteration is developing towards intelligence, lightweighting, and greening, becoming core equipment for equipment maintenance in the Industry 4.0 era.

A handle 7 is fixedly mounted on the upper end of the threaded rod 6. A pressing head 8 is provided at the lower end of the threaded rod 6. A connecting shaft 9 is provided inside the mounting base 1. One end of the connecting shaft 9 extends to the inside of the mounting base 1 and is fixedly mounted with a threaded rod 10. The other end of the connecting shaft 9 extends to the outside of the mounting base 1 and is fixedly mounted with a gear 11. A gear ring 12 is fixedly mounted on the upper end of the connecting ring 4. A gear ring 13 is fixedly installed on the inner surface. A drive shaft 14 is provided on the front side of the upper end of the mounting base 1. A gear 15 is fixedly installed on the surface of the drive shaft 14. A knob 16 is fixedly installed on the outer side of the protective shell 3 at the upper end of the drive shaft 14. The bearing is placed on the upper end of the three support frames 2. By rotating the handle 7 and the threaded rod 6, the pressing head 8 moves downward and presses against the bearing support, making it easy to lift the bearing, thereby completing the bearing disassembly. The bearing disassembly and assembly tool is simple to operate and is an integrated disassembly and assembly tool. By rotating the knob 16 and the drive shaft 14, the gear 15 drives the gear ring 13 and the connecting ring 4 to rotate. The gear ring 12 drives the gear 11 and the connecting shaft 9 to rotate, which causes the threaded rod 10 to drive the support frame 2 to move, thereby synchronously adjusting the spacing of the three support frames 2.

[0028] Please see Figure 1 and Figure 2 In this embodiment, the lower end of the connecting ring 4 is rotatably connected to the mounting base 1, and the surface of the threaded rod 6 is rotatably connected to the mounting frame 5. The mounting frame 5 has a U-shaped structure, and the support frame 2 is slidably connected to the mounting base 1. After adjusting the support frame 2, the bearing is placed on the upper end of the three support frames 2. By rotating the handle 7, the threaded rod 6 is rotated, causing the threaded rod 6 to drive the extrusion head 8 to move downward, so that the extrusion head 8 presses against the bearing support, making it easy to lift the bearing, thereby completing the bearing disassembly work. The bearing disassembly and assembly tool is simple to operate and is an integrated disassembly and assembly tool, which is conducive to improving the convenience of using, storing and carrying the bearing disassembly and assembly tool.

[0029] Please see Figures 1-5In this embodiment, the surface of the connecting shaft 9 is rotatably connected to the mounting base 1, the end of the threaded rod 10 away from the connecting shaft 9 is rotatably connected to the mounting base 1, the surface of the threaded rod 10 is threadedly connected to the support frame 2, a slide rod 17 is fixedly installed on the inner side of the mounting base 1 and the side of the threaded rod 10, the surface of the slide rod 17 is slidably connected to the support frame 2, the gear ring 12 is meshed with the gear 11, the gear 15 is meshed with the gear ring 13, the surface of the transmission shaft 14 is rotatably connected to the protective shell 3, and the lower end of the transmission shaft 14 is rotatably connected to the mounting base 1. By rotating the knob 16, the transmission shaft 14 is driven to rotate, which causes the gear 15 to drive the gear ring 13 and the connecting ring 4 to rotate. The connecting ring 4 and the gear ring 12 drive the gear 11 to rotate, which causes the connecting shaft 9 to drive the threaded rod 10 to rotate, further driving the support frame 2 to move. This facilitates the synchronous adjustment of the spacing of the three support frames 2, thereby adapting to the disassembly and assembly of bearings of various sizes and expanding the applicability of bearing disassembly and assembly tools.

[0030] During operation, after adjusting the support frame 2, place the bearing on the upper end of the three support frames 2. By rotating the handle 7, the threaded rod 6 is rotated, causing the threaded rod 6 to move the pressing head 8 downwards. The pressing head 8 then presses against the bearing support, making it easy to lift the bearing and complete the bearing disassembly. The bearing disassembly and assembly tool is simple to operate and is an integrated tool. By rotating the knob 16, the transmission shaft 14 is rotated, causing the gear 15 to drive the gear ring 13 and the connecting ring 4 to rotate. The connecting ring 4 and the gear ring 12 drive the gear 11 to rotate, causing the connecting shaft 9 to drive the threaded rod 10 to rotate, further moving the support frame 2. This allows for simultaneous adjustment of the spacing between the three support frames 2, thus adapting to the disassembly and assembly of bearings of various sizes.

[0031] Through the above steps, the bearing is placed on the upper end of the three support frames 2. By rotating the handle 7 and the threaded rod 6, the pressing head 8 moves downward and presses against the bearing support, making it easy to lift the bearing, thereby completing the bearing disassembly. The bearing disassembly and assembly tool is simple to operate and is an integrated disassembly and assembly tool, which solves the problem that bearing disassembly and assembly tools have many assembly parts, need to be combined and used, have a more complicated operation process, and are not conducive to centralized storage and carrying.
