Description

A quick-change structure for split compressor bushings Technical Field

[0001] This utility model belongs to the field of compressor bushing technology, specifically relating to a quick-change structure for split compressor bushings. Background Technology

[0002] After a certain period of use, the bushings inside the drive unit bearing housing of the compressor need to be replaced. Wear and tear on the bushings can increase the clearance between them and the bearings, affecting the stability and reliability of the compressor. Replacing the bushings restores the precise fit between them and the bearings, ensuring normal bearing operation and reducing vibration and noise.

[0003] Current methods for replacing bushings generally require the use of expansion devices to expand the bushing within the bearing housing. This deformation increases the friction between the bushing and the bearing housing, thus securing it in place. This method requires significant force to remove the bushing from the bearing housing, and the installation process is cumbersome and complex, necessitating the use of external tools. This not only prolongs compressor maintenance time and affects its normal operation but also makes the bushing replacement process tedious and impractical. Summary of the Invention

[0004] The purpose of this utility model is to provide a quick-replacement structure for split compressor bushings. By adding an adapter ring to the outside of the bushing, the bushing can be easily removed with just a screwdriver without the need for any other external facilities each time it is replaced.

A connecting ring is fixedly connected to the inner ring of the bearing. An adapter ring is provided inside the connecting ring. The adapter ring is hollow. A bushing body is assembled inside the adapter ring. A replacement component is provided inside the adapter ring.

[0007] The replacement component includes an annular bevel gear disk rotatably connected to the bottom surface of the inner cavity of the adapter ring. A bevel gear meshes on the upper side of the annular bevel gear disk. A rotating shaft is fixedly connected to the side wall of the bevel gear. The rotating shaft is rotatably connected to the inner wall of the adapter ring. The other end of the rotating shaft passes through the bevel gear and is fixedly connected to a worm gear. A worm is meshed on one side of the worm gear. The worm passes through the adapter ring and is fixedly connected to a rotating plate. The rotating plate is rotatably connected to the adapter ring. A locking component is provided on the side wall of the annular bevel gear disk.

[0008] The locking assembly includes multiple triangular blocks connected to the side wall of the annular bevel gear disk.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] As shown in Figures 1-6, a quick-change structure for a split compressor bushing includes a bearing housing 1, a through hole on the bearing housing 1, a bearing 2 installed in the through hole, a connecting ring 3 fixedly connected to the inner ring of the bearing 2, a transition ring 4 provided on the inner side of the connecting ring 3, the transition ring 4 being hollow, a bushing body 18 installed on the inner side of the transition ring 4, and a replacement component provided inside the transition ring 4.

[0024] As shown in Figures 3 and 5, the replacement component includes an annular bevel gear disk 5 rotatably connected to the bottom surface of the inner cavity of the adapter ring 4. A bevel gear 6 meshes with the upper side of the annular bevel gear disk 5. A rotating shaft 7 is fixedly connected to the side wall of the bevel gear 6. The rotating shaft 7 is rotatably connected to the inner wall of the adapter ring 4. The other end of the rotating shaft 7 passes through the bevel gear 6 and is fixedly connected to a worm gear 8. A worm 9 meshes with one side of the worm gear 8. The worm 9 passes through the adapter ring 4 and is fixedly connected to a rotating plate 10. The rotating plate 10 is rotatably connected to the adapter ring 4. A locking component is provided on the side wall of the annular bevel gear disk 5.

[0025] The bushing body 18 can be quickly disassembled and installed from the bearing housing 1 by using the replacement component. The process is convenient and quick, and it will not cause deformation to the bushing body 18. On the one hand, it shortens the maintenance time of the compressor, and on the other hand, it reduces the cumbersomeness of replacing the bushing body 18, making it highly practical.

[0026] As shown in Figure 6, the locking assembly includes multiple triangular blocks 11 connected to the side wall of the annular bevel gear disk 5, multiple movable rods 14 movably connected to the side wall of the adapter ring 4, multiple grooves 12 are provided on the outer wall of the adapter ring 4, one end of the movable rod 14 extends into the groove 12 and is fixedly connected to the insertion rod 13, the inner wall of the connecting ring 3 is provided with an insertion hole 15 corresponding to the insertion rod 13, and a spring 16 is sleeved on the side wall of the movable rod 14.

[0027] Specifically, the movable rod 14 and the insertion rod 13 are arranged in a circular array along the adapter ring 4, and there are at least six of them. This can achieve uniform force distribution between the adapter ring 4 and the connecting ring 3, and also ensure the rotational accuracy of the shaft when it rotates within the bushing body 18. Using the force of the spring 16, when the reverse rotating plate 10 disassembles the bushing body 18, it is convenient to drive the insertion rod 13 out of the insertion hole 15, while ensuring that one end of the movable rod 14 always abuts against the inclined surface of the triangular block 11.

[0028] The other end of the movable rod 14 is rotatably connected to a ball bearing 17, which abuts against the inclined surface of the triangular block 11. The ball bearing 17 reduces the friction between the movable rod 14 and the triangular block 11, further improving the smoothness of movement.

[0029] As shown in Figure 4, the bushing body 18 and the adapter ring 4 are connected by threads.

[0030] Multiple screws are movably connected to the end face of the bushing body 18, and the screws are threadedly connected to the adapter ring 4. Before installation, the bushing body 18 needs to be screwed onto the inside of the adapter ring 4 to add a mating structure to the outside of the bushing body 18, so that the insertion rod 13 can be inserted into the insertion hole 15. In addition, the screw connection method can serve as a replacement fixing structure and further increase the stability of the bushing body 18.

[0031] The working principle of this utility model is as follows: When the bushing body 18 needs to be installed, the bushing body 18 is first screwed onto the adapter ring 4 by threads. After being screwed to the appropriate position, it is then fixed again with screws. Then, the bushing body 18 and the adapter ring 4 are placed inside the connecting ring 3 and adjusted to the appropriate position. Next, the rotating plate 10 is rotated by a screwdriver to drive the worm 9 to rotate. The worm 9 meshes with the worm wheel 8 and drives the bevel gear 6 to rotate. The bevel gear 6 drives the annular bevel gear disk 5 to rotate. The annular bevel gear disk 5 drives the triangular block 11 to rotate. The inclined surface of the triangular block 11 pushes the movable rod 14 outward. The movable rod 14 drives the insertion rod 13 to be inserted into the insertion hole 15. Since the worm wheel 8 and the worm 9 have self-locking properties, it can be ensured that the insertion rod 13 will not disengage from the insertion hole 15, thereby realizing the quick replacement of the bushing body 18.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
