Description

Technical Field

[0001] This application relates to a disassembly fixture, and more particularly to a disassembly fixture for connecting bearings. Background Technology

[0002] In the maintenance and repair of mechanical equipment, bearings, as core rotating components, are frequently disassembled. For certain types of connecting bearings, such as articulated bearings, their structure typically consists of two main parts: an inner race and an outer housing. When a bearing needs to be replaced due to wear, failure, or major equipment overhaul, the inner race must be disassembled from the outer housing.

[0003] In existing technologies, operators typically use tools such as hammers, punches, and pry bars to try to remove the rotor shaft from its housing by striking or prying its edges. This method is not only time-consuming and labor-intensive, but it can also easily cause scratches, deformation, and other damage to bearing components (especially mating surfaces or oil seal grooves), and may even endanger the safety of operators. Utility Model Content

[0004] This application provides a connecting bearing disassembly fixture to solve the problems existing in related technologies. The technical solution is as follows: This application provides a connecting bearing disassembly fixture, including: support; Support rod, which is mounted on the bracket; The engaging component is mounted on the support rod, and the rotor corresponds to the engaging component. The disassembly assembly is mounted on the support rod and engages with the rotor shaft, while the engaging component engages with the rotor.

[0005] In one implementation, The disassembly components include: The disassembly head engages with the rotor shaft. A lead screw is mounted on a support rod and moves along the support rod. A connecting bearing is mounted on the lead screw, and a disassembly head is mounted on the lead screw via the connecting bearing. When the lead screw moves along the support rod, the disassembly head rotates relative to the lead screw, causing the rotor shaft to move with the lead screw. The engaging component engages with the rotor. When the lead screw rotates, the engaging component fixes the position of the rotor, thereby separating the rotor shaft from the rotor.

[0006] In one implementation, The disassembly head has holes that fit the rotor shaft.

[0007] In one implementation, The cross-section of the locking component is arc-shaped, and the shape of the locking component is adapted to the rotor.

[0008] In one implementation, The engaging part has a protrusion, and the rotor has a recess. The protrusion and the recess correspond to each other. When the lead screw moves along the support rod, the protrusion is located at the recess.

[0009] In one implementation, it further includes: The placement slot is set on the bracket. When the rotor shaft is removed from the rotor, the rotor falls into the placement slot.

[0010] In one implementation, it further includes: The protrusion is set on the support rod, the lead screw is set on the protrusion, and the part of the protrusion is located above the placement groove.

[0011] In one implementation, it further includes: The mounting block is mounted on the support rod, and the locking element is detachably mounted on the mounting block.

[0012] In one implementation, The placement slot is lined with a sponge pad.

[0013] The advantages or beneficial effects of the above technical solutions include at least the following: The engaging component engages with the bearing housing. During the rotation and lifting motion of the disassembly assembly, the rotor shaft moves up and down. The engaging component fixes the rotor's position, thereby enabling the inner liner to be removed from the housing through the rotation and lifting of the disassembly assembly. This improves the efficiency of bearing disassembly and saves labor costs.

In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of this application will become readily apparent from the accompanying drawings and the following detailed description.

[0017] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0018] Figures 1-3 This diagram illustrates the structure of a connecting bearing disassembly fixture according to an embodiment of this application. Figures 1-3 As shown, the disassembly fixture may include: Bracket 100; Support rod 200, which is mounted on bracket 100; The engaging component 300 is mounted on the support rod 200, and the rotor corresponds to the engaging component 300. The disassembly assembly 400 is mounted on the support rod 200 and engages with the rotor shaft. The engaging component 300 engages with the rotor.

[0019] In this embodiment, the rotor is mounted on the disassembly assembly 400. When the disassembly assembly 400 is rotated, it moves up and down along the support rod 200. When the connecting bearing 430 moves to the engaging member 300, the rotor engages with the engaging member 300. At this time, if the disassembly assembly 400 is rotated again, the rotor will stop rotating under the action of the engaging member 300 and the position will be locked. If the disassembly assembly 400 is rotated again, the rotor shaft will be pulled out of the housing. The disassembly assembly 400 is engaged with the rotor shaft. The disassembly assembly 400 works in conjunction with the engaging component 300, which engages the bearing housing. During the rotation and lifting motion of the disassembly assembly 400, the rotor shaft moves up and down. The engaging component 300 fixes the position of the rotor, thereby enabling the inner liner to be removed from the housing by rotating and lifting the disassembly assembly 400. This improves the efficiency of disassembling the connecting bearing 430 and saves labor costs.

[0020] like Figures 1-3 As shown, in one embodiment, Disassembly component 400 includes: Disassembly head 410, disassembly head 410 engages with rotor shaft; Lead screw 420 is mounted on support rod 200 and moves along support rod 200; A connecting bearing 430 is mounted on a lead screw 420. A disassembly head 410 is mounted on the lead screw 420 via the connecting bearing 430. When the lead screw 420 moves along the support rod 200, the disassembly head 410 rotates relative to the lead screw 420, causing the rotor shaft to move with the lead screw 420. A locking member 300 engages with the rotor. When the lead screw 420 rotates, the locking member 300 fixes the position of the rotor, thereby separating the rotor shaft from the rotor.

[0021] In this embodiment, the lead screw 420 is threadedly connected to the support rod 200. When the lead screw 420 rotates, it moves up and down along the support rod 200, which in turn drives the disassembly head 410 to move up and down. When the rotor engages with the engaging member 300, the lead screw 420 rotates normally under the action of the connecting bearing 430, while the disassembly head 410 can still move up and down, thus ensuring that the rotor shaft can be disassembled by rotating the lead screw 420.

[0022] like Figures 1-3 As shown, in one embodiment, The disassembly head 410 has a hole for rotor shaft adaptation.

[0023] In this embodiment, the rotor shaft is adapted to the hole on the disassembly head 410. The disassembly head 410 engages with the rotor shaft through the hole, thereby enabling the rotor shaft to move up and down.

[0024] In one implementation, The cross-section of the locking component 300 is arc-shaped, and the shape of the locking component 300 is adapted to the rotor.

[0025] In this embodiment, the engaging component 300 has an arc-shaped structure, which facilitates its engagement with the rotor, thereby locking the rotor in place and fixing its position.

[0026] like Figures 1-3 As shown, in one embodiment, The engaging part 300 has a protrusion 310 and the rotor has a recess. The protrusion 310 corresponds to the recess. When the lead screw 420 moves along the support rod 200, the protrusion 310 is located at the recess.

[0027] In this embodiment, the protrusion 310 on the engaging member 300 blocks the rotor, preventing the rotor from continuing to rotate, and also preventing the rotor from continuing to move up and down with the disassembly head 410, thereby facilitating the disassembly head 410 to pull the rotor shaft out of the rotor.

[0028] like Figure 1 As shown, in one embodiment, it further includes: Placement slot 500 is set on bracket 100. When the rotor shaft is removed from the rotor, the rotor falls into placement slot 500.

[0029] In this embodiment, by setting up the placement groove 500, when the rotor shaft is separated from the rotor, the rotor falls into the placement groove 500, which prevents the rotor from falling and being damaged. At the same time, the placement groove 500 collects the oil stains generated during bearing disassembly, which prevents pollution to the surrounding environment.

[0030] like Figures 1-3 As shown, in one embodiment, it further includes: The protrusion 210 is mounted on the support rod 200, and the lead screw 420 is mounted on the protrusion 210. Part of the protrusion 210 is located above the placement groove 500.

[0031] In this embodiment, the protrusion 210 and the support rod 200 form an inverted "L" shape structure, and the lead screw 420 is set on the protrusion 210, thereby ensuring that the lead screw 420 is located above the placement groove 500, and ensuring that when the rotor shaft is separated from the rotor, the rotor falls into the placement groove 500.

[0032] like Figures 1-3 As shown, in one embodiment, it further includes: Mounting block 220 is mounted on support rod 200, and engaging member 300 is detachably mounted on mounting block 220.

[0033] In this embodiment, the locking component 300 is detachably mounted on the mounting block 220, and different locking components 300 can be replaced according to the bearing model.

[0034] like Figure 1 As shown, in one embodiment, The placement slot 500 is equipped with a sponge pad.

[0035] In this embodiment, the sponge pad is used to prevent the rotor from falling directly into the placement slot 500 and causing a collision that could damage the rotor.
