Description

Technical Field

[0001] This utility model relates to the technical field of shaft-mounted parts repair tools, and in particular to a shaft-mounted parts disassembly device. Background Technology

[0002] Bearings are an important component in modern machinery. Their main function is to support rotating parts of the machine, reduce the coefficient of friction during movement, and ensure rotational accuracy. For large machinery, bearings are usually quite large, making disassembly relatively complicated.

[0003] The problems with existing disassembly devices are that the disassembly tools commonly used in related technologies are structurally flimsy and cannot disassemble the holes and shaft mating parts in these large equipment, resulting in long equipment maintenance time, affecting the normal operation of the equipment and causing significant losses. At the same time, one type of equipment can only disassemble shaft parts of one size and cannot meet the disassembly of shaft parts of multiple sizes, resulting in poor versatility of the disassembly device. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a shaft-mounted parts disassembly device to solve the issues that existing disassembly devices cannot meet the disassembly requirements of large shaft-mounted parts and have poor versatility and convenience.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a shaft-mounted parts disassembly device, including a frame, a groove in the middle of the frame, a hydraulic jack at one end of the frame, a through hole at the other end of the frame, a limiting gate in the through hole, and a lifting mechanism at the top of the limiting gate.

[0006] As a further embodiment of this utility model: the groove is provided with evenly spaced pad slots, and pads are placed in the pad slots.

[0007] As a further improvement of this utility model: the pad has an arc-shaped groove and handles at both ends.

[0008] As a further embodiment of this utility model: the hydraulic jack includes a cylinder, which is located on the outside of the frame, and a piston rod is provided inside the cylinder, which passes through the frame and extends into a groove.

[0009] As a further embodiment of this utility model: the lifting mechanism includes a lead screw, the bottom end of which is fixedly connected to the top end of the limiting gate through a flange, the top end of which passes through the frame and is helically connected to a worm gear, a worm is meshed on the worm gear, and a motor is connected to the end of the worm.

[0010] As a further improvement of this utility model: the worm gear is connected to the output end of the motor via a plum blossom-shaped elastic coupling.

[0011] As a further improvement of this utility model: the upper part of the through hole is rectangular, the lower part is arc-shaped, and the bottom of the through hole is provided with an arc-shaped protrusion.

[0012] As a further improvement of this utility model: the bottom of the limiting gate is arc-shaped, and the two sides of the limiting gate are slidably connected to the inner wall of the through hole.

[0013] As a further improvement of this utility model, the edge of the arc-shaped groove of the pad is provided with a stepped groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model allows for the selection of appropriate pads to be placed in the pad slot according to the size of the disassembly shaft, increasing the versatility of the device and ensuring that the hydraulic jack can always be positioned at the center line of the disassembly shaft. The pads not only facilitate the stable placement of the disassembly shaft but also help to hold the parts on the disassembly shaft in place, enabling the device to operate stably.

[0016] 2. The lifting mechanism of this utility model adopts a worm gear mechanism, which gives the lifting mechanism a self-locking characteristic. When the limit gate stops moving, due to the self-locking characteristic of the lifting mechanism, it will not move downward due to its own gravity, thus ensuring the stability of the device operation and ensuring the normal completion of disassembly.

[0017] 3. This utility model adopts the combination of lifting mechanism and hole limiting gate, which can flexibly adjust the size of the blocking hole in the device, shorten the adjustment time and improve work efficiency;

[0018] 4. This utility model uses a plum blossom-shaped flexible coupling between the motor and the worm gear, which can compensate for shaft misalignment, buffer and reduce vibration, reduce working noise, protect the equipment, and extend the service life of the equipment while transmitting torque.

[0019] 5. This utility model stabilizes the shaft while preventing it from sliding or rolling, making operation convenient and quick, improving disassembly efficiency and versatility. It features easy assembly and strong disassembly force, and can be applied to the disassembly of longer shafts and bearings. Attached Figure Description
