[0002] The swingarm of a motorcycle connects the frame and the rear wheel, serving to fix the rear wheel, bear the weight of the frame, and maintain stability. The swingarm contains bearings, whose main function is to support rotating mechanical parts, reduce the coefficient of friction during movement, and ensure rotational accuracy. The bearings are installed in the motorcycle's swingarm to reduce its coefficient of friction.

[0003] The process of installing bearings into the rear swingarm of a motorcycle requires a press-fitting process. However, most existing press-fitting processes are done manually. The disadvantages of this method are that manual control is difficult, uneven force can easily cause misalignment, and the bearing can be easily damaged. In addition, manual operation increases labor intensity. Utility Model Content

[0046] Example 1

[0047] This embodiment provides a motorcycle rear swingarm bearing press-fitting device, such as... Figures 1 to 4 As shown, the assembly includes a mounting base 100, a rear rocker arm 200, a first pressing assembly, and a second pressing assembly. The upper surface of the mounting base 100 has a slot for inserting into the rear rocker arm 200 to limit its position. The slot's shape is adapted to the shape of the rear rocker arm 200 for better positioning. The slot's depth must be such that after the rear rocker arm 200 is inserted into the slot, all bearing holes of the rear rocker arm 200 are located outside the slot. The rear rocker arm 200 has multiple bearing holes; in this embodiment, three bearing holes are used as an example, but the number of bearing holes can be adjusted as needed. The first pressing assembly includes a first driving component 301 and multiple first pressing heads 302. The number of first pressing heads 302 is the same as the number of bearing holes, and the position of each first pressing head 302 corresponds one-to-one with the position of the corresponding bearing hole. Each first pressing head 302 is connected to the first driving component 301. The first driving component 301 can be a linear motor 601 or other common linear motion devices. In this embodiment, the first driving component 301 is a hydraulic cylinder. The end of the telescopic rod of the first driving component 301 is fixedly connected to a first bearing plate. All the first pressing heads 302 are spaced apart on the first bearing plate. The first driving component 301 can drive each first pressing head 302 to be inserted into the corresponding bearing hole. When it is necessary to press the bearing, each bearing can be respectively sleeved on the corresponding first pressing head 302. The second pressing assembly and the first pressing assembly are located on both sides of the rear rocker arm 200. The second pressing assembly includes a second driving member 401 and a plurality of second pressing heads 402. The number of second pressing heads 402 is the same as the number of bearing holes, and the position of each second pressing head 402 corresponds one-to-one with the position of the corresponding bearing hole. Each second pressing head 402 is connected to the second driving member 401. The second driving member 401 can be a linear motor 601 or other common linear motion devices. In this embodiment, the second driving member 401 is a hydraulic cylinder. The end of the telescopic rod of the second driving member 401 is fixedly connected to a second bearing plate. All the second pressing heads 402 are spaced apart on the second bearing plate. The second driving member 401 can drive each second pressing head 402 to be inserted into the corresponding bearing hole.

[0048] In this example, the first and second pressing components are located on both sides of the rear swingarm 200, and each pressing head corresponds one-to-one with the bearing hole on the rear swingarm 200. This method of applying pressure simultaneously from both sides ensures that the bearing is subjected to uniform force during the pressing process, effectively avoiding bearing misalignment and damage during installation, significantly improving the stability of the pressing operation and the installation quality of the bearing. In addition, the motorcycle rear swingarm bearing pressing device provided in this application requires no manual operation, reducing labor intensity and improving work efficiency. Furthermore, this motorcycle rear swingarm bearing pressing device can press multiple bearings at a time, further improving work efficiency.

[0049] like Figure 2 As shown, in the motorcycle rear swingarm bearing press-fitting device provided in this embodiment, each first press head 302 has a first protrusion 3021, and a corresponding bearing is fitted around the outer periphery of the first protrusion 3021. The first protrusion 3021 is cylindrical, which facilitates the installation of the bearing on the corresponding first protrusion 3021 and reduces the possibility of the bearing falling off the press head during the press-fitting process.

[0050] like Figure 2 As shown, the motorcycle rear swingarm bearing press-fitting device provided in this embodiment includes a first protrusion 3021 comprising a first sub-protrusion 30211 and a second sub-protrusion 30212 connected to each other. A corresponding bearing is fitted onto the first sub-protrusion 30211, and a first seal is fitted onto the second sub-protrusion 30212. The first press head 302 can not only press the bearing into the corresponding bearing hole but also press-fit the first seal.

[0051] like Figure 3 As shown, the motorcycle rear swingarm bearing press-fit device provided in this embodiment includes a second protrusion 4021, each of which is cylindrical and is used to fit a second seal. The second press head 402 can press the second seal into the corresponding bearing hole.

[0052] like Figure 1 and Figure 4As shown, the motorcycle rear swingarm bearing press-fitting device provided in this embodiment also includes a worktable 500, which is a plate. Additionally, a buffer pad can be provided at the bottom of the worktable 500 to reduce vibration. A first support plate 501 is fixedly connected to the worktable 500, and the mounting seat 100 of the first drive member 301 is fixedly fixed to the first support plate 501. A second support plate 502 is fixedly connected to the worktable 500, and the mounting seat 100 of the second drive member 401 is fixedly connected to the second support plate 502. Both ends of the support rod 503 are fixedly connected to the first support plate 501 and the second support plate 502 respectively, increasing the rigidity of the entire device. Both the first drive member 301 and the second drive member 401 are fixedly connected to the worktable 500, and the first drive member 301 and the second drive member 401 are arranged opposite to each other. The mounting seat 100 is connected to the worktable 500, and the worktable 500 is located between the first drive member 301 and the second drive member 401. The worktable 500 serves as a supporting base, firmly connecting the first drive component 301 and the second drive component 401 together to form a stable frame structure. This significantly enhances the stability and rigidity of the overall structure, helps maintain high precision and stability during the press-fitting process, and thus improves the installation quality of the bearing.

[0053] like Figure 1 and Figure 4 As shown, the motorcycle rear swingarm bearing press-fitting device provided in this embodiment also includes a third drive component. The third drive component is connected to the worktable 500 and the mounting base 100 respectively, and the third drive component can drive the mounting base 100 to rotate at a set angle. The third drive component can be a motor 601 or other common rotary motion devices.

[0054] like Figure 4 As shown, the motorcycle rear swingarm bearing press-fitting device provided in this embodiment includes a third driving component comprising a motor 601, an intermittent gear 602, and a meshing gear 603. The motor 601 is fixedly connected to the worktable 500; the intermittent gear 602 is fixedly connected to the output shaft of the motor 601, and has a meshing portion 6021 and an intermittent portion 6022; the meshing gear 603 is rotatably connected to the worktable 500 and fixedly connected to the mounting base 100; the meshing portion 6021 has a flipped position that meshes with the meshing gear 603; the intermittent portion 6022 has an intermittent position that rotates relative to the meshing gear 603; the motor 601 can drive the intermittent gear 602 to rotate, switching between the flipped position and the intermittent position. The meshing portion 6021 consists of multiple teeth on the intermittent gear 602, and the intermittent portion 6022 is a toothless portion on the intermittent gear 602. In the initial state (i.e., before operation begins), the intermittent gear 602 is in the intermittent position.

[0055] like Figure 1As shown, the motorcycle rear swingarm bearing press-fitting device provided in this embodiment also includes a protective housing 700, which is fixedly connected to the worktable 500. The meshing gear 603 and the intermittent gear 602 are located inside the protective housing 700. The design of the protective housing 700 effectively isolates the meshing gear 603 and the intermittent gear 602 from direct contact with the external environment, avoiding the risk of injury to the operator due to accidental contact or other unforeseen circumstances. At the same time, the protective housing 700 also prevents dust, debris, and other impurities from entering the transmission system, protecting the internal components from damage and extending the service life of the device.

[0056] In this embodiment, the working process of the motorcycle rear swingarm bearing press-fitting device is as follows:

[0057] First, each bearing is fitted onto the corresponding first sub-protrusion 30211 until the bearing abuts against the top of the second sub-protrusion 30212. At this point, the bearing is flush with the top of the first sub-protrusion 30211. Then, the second drive member 401 drives each second protrusion 4021 to move toward the rear rocker arm 200 until each second protrusion 4021 is inserted into the corresponding bearing hole and abuts against the mounting plate in the corresponding bearing hole. The mounting plate has through holes for cooperating with the transmission components of the motorcycle. Then, the first drive member 301 works, driving each bearing to extend into the bearing hole until each bearing abuts against the other side of the corresponding mounting plate, and the bearing press-fit is completed. While the first driving member 301 is working, the motor 601 is working, driving the intermittent gear 602 to rotate. At this time, it is in the intermittent position. After the pressing is completed, the intermittent gear 602 is exactly in the flip position, that is, the meshing part 6021 meshes with the meshing gear 603, and drives the meshing gear 603 to rotate, so as to drive the mounting base 100 to rotate until the mounting base 100 is flipped 180°. Then, the first sealing member is sleeved on the outer periphery of the second sub-protrusion, and the second sealing member is sleeved on the outer periphery of the second protrusion 4021. Then, the first driving member 301 and the second driving member 401 respectively drive the second sub-protrusion and the second protrusion to approach each other and insert into the corresponding bearing hole sides to realize the pressing of the first sealing member and the second sealing member. The first sealing member and the second sealing member can be sealing rings.

[0058] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
