Description

Technical Field

[0001] This utility model relates to the field of shaft connector disassembly technology, and specifically to a shaft connector disassembly device. Background Technology

[0002] A shaft coupling is a mechanical part used to connect two shafts (driving shaft and driven shaft) in a mechanical transmission system. Its core function is to transmit motion and torque, while compensating for the relative displacement (such as axial, radial, and angular deviations) that may occur between the two shafts during installation or operation. It also buffers vibration, reduces impact, and protects equipment in the transmission system (such as motors and reducers) to a certain extent.

[0003] After prolonged use, shaft connectors may need to be disassembled for equipment maintenance, troubleshooting, structural adjustments, or performance optimization. The current disassembly method usually involves using a pry bar, which is time-consuming and labor-intensive, and can easily damage the edges of the shaft connector, thus affecting its service life. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a shaft connector disassembly device to solve the problem mentioned in the background art that the existing technology of disassembling shaft connectors by prying bars is time-consuming and labor-intensive, and is prone to damaging the edges of the shaft connectors, thereby easily affecting the service life of the shaft connectors.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a shaft coupling disassembly device, comprising: a pull rod, a support frame, a locking mechanism, a sliding hammer, and a force-bearing mechanism. One end of the pull rod is provided with a locking thread, and the other end of the pull rod is provided with a fixing thread. A through hole is provided on the support frame, and the locking thread is located inside the through hole. The locking mechanism is disposed on the locking thread and is used to press the support frame. The sliding hammer is slidably disposed on the pull rod, and the force-bearing mechanism is disposed on the fixing thread and is used to withstand the impact of the sliding hammer.

[0008] Preferably, the locking mechanism includes a locking nut, a pressure plate, and a rolling assembly. The locking nut is threaded onto a locking thread, the pressure plate is fixedly connected to one side of the locking nut, and the rolling assembly is disposed on the pressure plate to support the pressure plate and the locking nut to rotate on the support frame.

[0009] Furthermore, the rolling assembly includes: a rotating seat and a rolling wheel. Multiple rotating seats are provided, and each rotating seat is fixedly connected to the other side of the pressure plate. Each rotating seat is rotatably connected to a rolling wheel, and one side of each rolling wheel is in contact with one side of the support frame.

[0010] Furthermore, the force-bearing mechanism includes a force-bearing plate and a fixing nut. The force-bearing plate has a through hole, the fixing thread is located inside the through hole, and the fixing nut is threaded onto the fixing thread.

[0011] As a further aspect of this application, an operating lever is fixedly connected to the sliding hammer.

[0012] As a further improvement in this application, both ends of the pull rod are chamfered.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a shaft coupling disassembly device, which has the following advantages:

[0015] In this invention, when the coupling is installed tightly, the locking thread is screwed onto the coupling, and the support bracket fitted on the locking thread is pressed against the equipment. Then, the operator rotates the locking mechanism to pull the coupling outward. When the coupling is loose, a force-bearing mechanism is installed on the fixing thread, and the operator pulls the sliding hammer on the pull rod to strike the force, thereby quickly disassembling the coupling. Compared with pry bar disassembly, this disassembly method is more time-saving and labor-saving, improves the disassembly efficiency of the coupling, and is less likely to damage the coupling, thus increasing the service life of the coupling.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 A shaft coupling disassembly device includes: a pull rod 1, a support frame 4, a locking mechanism, a sliding hammer 5, and a force-bearing mechanism. Both ends of the pull rod 1 are chamfered. An operating rod 12 is fixedly connected to the sliding hammer 5. One end of the pull rod 1 is provided with a locking thread 2, and the other end of the pull rod 1 is provided with a fixing thread 3. A through hole is provided on the support frame 4, and the locking thread 2 is located in the through hole. The locking mechanism is provided on the locking thread 2 and is used to press the support frame 4. The sliding hammer 5 is slidably provided on the pull rod 1, and the force-bearing mechanism is provided on the fixing thread 3 and is used to withstand the impact of the sliding hammer 5.

[0023] The locking mechanism includes a locking nut 6, a pressure plate 7, and a rolling assembly. The locking nut 6 is threaded onto the locking thread 2. The pressure plate 7 is fixedly connected to one side of the locking nut 6. The rolling assembly is mounted on the pressure plate 7 and is used to support the pressure plate 7 and the locking nut 6 to rotate on the support frame 4. The rolling assembly includes a rotating seat 8 and a rolling wheel 9. Multiple rotating seats 8 are provided, and each rotating seat 8 is fixedly connected to the other side of the pressure plate 7. Each rotating seat 8 has a rolling wheel 9 rotatably connected inside it, and one side of each rolling wheel 9 is in contact with one side of the support frame 4.

[0024] The operator twists the locking nut 6 to rotate on the locking thread 2, thereby causing the pressure plate 7 and the rolling wheel 9 to press against the support frame 4. When the locking nut 6 rotates, the rolling wheel 9 rolls on the support frame 4 and moves in the direction of the spiral of the locking thread 2, thereby pulling out the shaft connector.

[0025] The force-bearing mechanism includes a force-bearing plate 10 and a fixing nut 11. The force-bearing plate 10 has a through hole, and the fixing thread 3 is located in the through hole. The fixing nut 11 is threaded onto the fixing thread 3. The operator screws the fixing nut 11 onto the fixing thread 3 and pulls the operating rod 12 to drive the sliding hammer 5 to slide on the pull rod 1, thereby striking the force-bearing plate 10 and disassembling the shaft connector.

[0026] Working principle: When disassembling the shaft connector, if the shaft connector is installed too tightly, tighten the locking thread 2 at one end of the pull rod 1 onto the shaft connector. Then, the support frame 4, which is previously fitted onto the locking thread 2, rests against the equipment. The operator then twists the locking nut 6 to rotate on the locking thread 2, thereby driving the pressure plate 7 and the rolling wheel 9 to rest against the support frame 4. When the locking nut 6 rotates, the rolling wheel 9 rolls on the support frame 4 and moves in the direction of the spiral of the locking thread 2, thereby pulling out the shaft connector. If the shaft connector is too loose, simply tighten the fixing nut 11 onto the fixing thread 3, and the operator pulls the operating rod 12 to drive the sliding hammer 5 to slide on the pull rod 1, thereby striking the force plate 10 and disassembling the shaft connector.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
