Abstract
Description
Technical Field
[0001] This application relates to the field of mechanical maintenance technology, and in particular to a bearing disassembly tool. Background Technology
[0002] Bearings are crucial components in the machinery industry, widely used in various mechanical equipment. However, in some cases, machine repair or bearing replacement is necessary, requiring disassembly and reassembly of the bearings. In actual bearing disassembly, it is common to encounter situations where ordinary pullers cannot remove the bearings; there is no puller screw to reach the component that needs to be disassembled, making it impossible to remove the bearing from the housing. Utility Model Content
[0003] In view of this, this application proposes a bearing disassembly fixture.
[0004] According to one aspect of this application, a bearing disassembly fixture is provided, comprising: a support sleeve, a stud, and a connecting piece;
[0005] The support sleeve has a hollow, barrel-shaped structure with an opening at the bottom and a threaded hole at the center of the top. The bottom of the support sleeve contacts the outer shell of the part to be disassembled.
[0006] The stud has a cylindrical structure with external threads that match the mounting threaded hole. Rotating the stud allows it to move up and down.
[0007] The connecting piece is a plate-shaped structure and is disposed at the end of the stud. The connecting piece has a fixing hole for fixing the parts to be disassembled.
[0008] In one possible implementation, the connecting piece is spaced at a predetermined distance from the end of the stud.
[0009] In one possible implementation, the connecting piece has a preset thickness.
[0010] In one possible implementation, the direction of movement of the stud is perpendicular to the surface direction of the connecting piece, and rotating the stud causes the connecting piece to move relative to the support sleeve in the axial direction of the stud.
[0011] In one possible implementation, the support sleeve is a cylindrical structure.
[0012] In one possible implementation, the connecting piece is located inside the support sleeve, and the stud has a nut at one end near the connecting piece.
[0013] One possible implementation also includes a joystick;
[0014] The stud has a rotating hole at the end away from the connecting piece, and the direction of the rotating hole is perpendicular to the axial direction of the stud.
[0015] The rocker arm passes through the rotating hole, and rotating the rocker arm causes the stud to rotate circumferentially.
[0016] In one possible implementation, the interior of the support sleeve has a preset depth, and the connecting piece is spaced at a preset distance from the top of the support sleeve.
[0017] In one possible implementation, the mounting threaded hole is located at the middle position of the top of the support sleeve.
[0018] In one possible implementation, the connecting piece is a circular plate-like structure;
[0019] The stud passes through the center of the connecting piece for a fixed connection;
[0020] The fixing holes are multiple and spaced apart along the circumferential direction of the connecting piece.
[0021] The beneficial effects of the bearing disassembly fixture in this application embodiment are as follows: The connecting piece connects to the bearing, and the support sleeve abuts against the outer housing of the bearing. Because the support sleeve abuts against the top of the housing, rotating the stud lifts the connecting piece, causing the bearing to rise relative to the housing, thereby removing the bearing from the housing. Specifically, the screw is connected to the connecting piece and a nut is installed at the protrusion. Then, the connecting piece is connected to the component to be disassembled according to the screw hole positions and the screw is tightened. The support sleeve is connected to the screw, and finally, the support sleeve is screwed until it contacts the housing. A vise is used to clamp the cut edges on both sides of the support sleeve, and the screw is tightened counterclockwise until the component with the bearing detaches from the housing.

[0034] like Figure 1As shown, the bearing disassembly fixture of this application embodiment includes: a bearing disassembly fixture 200, a stud 100, and a connecting piece 300. The bearing disassembly fixture 200 has a hollow barrel-shaped structure inside, with an opening at the bottom and a threaded mounting hole 210 at the top. The bottom of the bearing disassembly fixture 200 is suitable for abutting against the housing outside the part to be disassembled. The stud 100 has a columnar structure with external threads that match the threaded mounting hole 210. The stud 100 is rotatably mounted on the top of the bearing disassembly fixture 200 and can move up and down along the opening direction of the threaded mounting hole 210. The connecting piece 300 has a plate-shaped structure and is located at the end of the stud 100. The plate surface is perpendicular to the axial length direction of the stud 100, and a fixing hole 310 is provided at the edge of the connecting piece 300 for fixing the bearing inside the part to be disassembled.
[0035] In this embodiment, the connecting piece 300 is connected to the fixed bearing component, and the bearing removal fixture 200 abuts against the outer housing of the bearing. Since the bearing removal fixture 200 abuts against the top of the housing, rotating the stud 100 lifts the connecting piece 300, causing the bearing and component to lift relative to the housing, thereby removing the bearing and component from the housing. Specifically, the screw is connected to the connecting piece 300 and a nut is installed on its protrusion. Then, the connecting piece 300 is connected to the component to be removed according to the screw hole positions and the screw is tightened. The bearing removal fixture 200 is connected to the screw. Finally, the bearing removal fixture 200 is screwed until it contacts the housing. A vise is used to clamp the cut edges on both sides of the bearing removal fixture 200, and the screw is tightened counterclockwise until the component with the bearing detaches from the housing.
[0036] The bearing disassembly fixture 200 has a bottom design for abutting against the outer shell of the part to be disassembled, ensuring the fixture's stability. The stud 100 is a columnar structure with external threads that match the mounting threaded hole 210. The stud 100 is rotatably mounted on top of the bearing disassembly fixture 200 and can reciprocate along the direction of the mounting threaded hole 210, achieving lifting and lowering through rotation. The connecting plate 300 is a plate-like structure located at the end of the stud 100, with its surface perpendicular to the axial length of the stud 100. The edge of the connecting plate 300 has a fixing hole 310 for fixing the bearing inside the part to be disassembled, ensuring a stable connection between the bearing and the fixture during disassembly.
[0037] In one specific embodiment, the ends of the connecting piece 300 and the stud 100 are spaced by a preset distance to provide sufficient operating space and ensure that the connecting piece 300 can be fixed to the bearing with bolts.
[0038] In one specific embodiment, the connecting piece 300 has a preset thickness to ensure the strength of the connecting piece 300 itself, which is sufficient to extract the bearing inside the housing.
[0039] In one specific embodiment, the movement direction of the stud 100 is perpendicular to the plate surface direction of the connecting piece 300. Rotating the stud 100 causes the connecting piece 300 to move relative to the bearing disassembly fixture 200 in the axial direction of the stud 100. Specifically, the axial direction of the stud is perpendicular to the plate surface direction of the connecting piece 300. When the stud 100 rotates and moves away from the bearing disassembly fixture 200, the connecting piece 300 moves away from the bearing disassembly fixture 200 along with the stud 100, causing the connecting piece 300 to lift and move the bearing and parts upward, thereby allowing the bearing to detach from the housing.
[0040] In one specific embodiment, the bearing removal fixture 200 has a cylindrical structure, which facilitates the bottom of the bearing removal fixture 200 to abut against the top of the housing and increases the contact area, making the bearing removal fixture 200 more stable when it abuts against the housing.
[0041] In one specific embodiment, the connecting piece 300 is located inside the bearing disassembly fixture 200, and the stud 100 is provided with a nut at one end near the connecting piece 300.
[0042] In one specific embodiment, a rocker arm 400 is also included. A rotating hole 110 is provided at the end of the stud 100 away from the connecting piece 300. The rotating hole 110 is perpendicular to the axial direction of the stud 100. The rocker arm 400 passes through the rotating hole 110, and rotating the rocker arm 400 causes the stud 100 to rotate circumferentially. The rocker arm 400 is designed to rotate the columnar stud 100. Specifically, a rotating hole 110 perpendicular to the axial direction can be provided at the top of the stud 100, allowing the rocker arm 400 to be inserted. By rotating the rocker arm 400, the stud 100 is rotated, thus lifting the bearing.
[0043] In one specific embodiment, the bearing disassembly fixture 200 has a preset depth inside, and the connecting piece 300 is spaced at a preset distance from the top of the bearing disassembly fixture 200 to accommodate a portion of the bearing, while ensuring that the connecting piece 300 and the top of the bearing disassembly fixture 200 are spaced at a preset distance to avoid interference.
[0044] In one specific embodiment, the mounting threaded hole 210 is located at the middle position of the top of the bearing disassembly fixture 200, which facilitates the alignment of the stud 100 and makes the bearing disassembly fixture 200 more evenly and stably subjected to force when the stud 100 is rotated.
[0045] In one specific embodiment, the connecting piece 300 is a circular plate-like structure. The stud 100 passes through the center of the connecting piece 300 for fixed connection. Multiple fixing holes 310 are spaced apart along the circumferential direction of the connecting piece 300. When the connecting piece 300 is a circular plate-like structure, multiple fixing holes 310 can be formed along the edge of the connecting piece 300. These multiple fixing holes 310 simultaneously connect with components inside the bearing bolt, improving the connection stability between the connecting piece 300 and the bearing. Furthermore, the overall stress on the connecting piece 300 is more uniform, preventing damage due to uneven stress.
[0046] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
