Technical Field

[0001] This utility model relates to the field of rotor shaft sealing technology, and in particular to a leak-proof, snap-fit ​​rotor shaft. Background Technology

[0002] As a core component in mechanical systems that enables power transmission and motion conversion, the rotor shaft is widely used in various mechanical equipment such as motors, pumps, fans, and automobile engines. In actual operation, the performance of the rotor shaft has a decisive impact on the overall operating efficiency, stability, and service life of the equipment.

[0003] A rotor shaft disclosed in publication number CN207715529U includes a left support section, a rotor mounting section, and a right support section. The left support section and the rotor mounting section are connected by a transition section. The outer ring of the left support section has a first straight groove knurling, and the outer ring of the rotor mounting section has a second straight groove knurling. From the left side of the second straight groove knurling towards the transition section, there are sequentially a second fine grinding section, a first fine grinding section, and a coarse grinding section. From the right side of the second straight groove knurling towards the right support section, there are sequentially a fourth fine grinding section, a third fine grinding section, and a fifth fine grinding section. A first relief groove is provided between the first and second fine grinding sections, and a second relief groove is provided between the fifth fine grinding section and the right support section.

[0004] While the aforementioned patent effectively disperses stress and avoids stress concentration and sharp edges, during use, gaps may form between the gasket and the device due to wear of the gasket or axial movement of the rotor shaft, leading to leakage of lubricating oil inside the device.

[0015] (III) Beneficial Effects

[0016] This utility model provides a leak-proof, sealing snap-on rotor shaft, which has the following advantages:

[0017] 1. This leak-proof, snap-fit ​​rotor shaft, through the setting of the sealing assembly, allows the I-shaped sealing gasket to be installed on the rotor shaft body during use. The support spring can disperse the contact stress between the I-shaped sealing gasket and the rotor shaft body, avoiding excessive local wear and thus extending the service life of the I-shaped sealing gasket. Secondly, the support spring can provide continuous elastic force to the I-shaped sealing gasket, ensuring that the sealing gasket can tightly fit the rotor shaft and the inner wall of the sealing cavity, and can also automatically compensate for the gap changes caused by gasket wear or axial movement of the rotor shaft. This allows the device to effectively block the leakage path of lubricating oil and ensure the reliability and stability of the seal.

[0018] 2. This leak-proof, oil-sealing snap-fit ​​rotor shaft, through the setting of snap-fit ​​components and snap-fit ​​rods, allows for quick installation and disassembly of the device. During installation, moving the sliding block causes the insertion rod to move, while the return spring is compressed. The device is then inserted into the mounting housing. Releasing the sliding block causes the return spring to reset the sliding block, and the insertion rod is inserted into the snap-fit ​​interface on one side of the snap-fit ​​rod, limiting the snap-fit ​​rod.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1 to 4This utility model provides a technical solution: a leak-proof, sealing snap-fit ​​rotor shaft, including a shaft housing 1. Two sets of snap-fit ​​rods 2 are fixedly connected to the outer side of the shaft housing 1. Each of the two sets of snap-fit ​​rods 2 has a snap-fit ​​assembly 3 inserted into its interior. The snap-fit ​​assembly 3 allows for quick installation and disassembly. A rotor shaft body 4 is located inside the shaft housing 1. A sealing assembly 5 is located on the inner side of the rotor shaft body 4. The sealing assembly 5 prevents lubricating oil leakage. Each of the two sets of snap-fit ​​assemblies 3 includes a snap-fit ​​rod 301 inserted into the two sets of snap-fit ​​rods 2. A sliding block 302 is fixedly connected to one end of each of the two sets of sliding blocks 302. A return spring 303 is fixedly connected to one side of each of the two sets of return springs 303. A moving rod 304 is sleeved inside each of the two sets of return springs 303. The sealing assembly 5 includes an I-shaped sealing gasket 501 located inside the rotor shaft body 4. Two sets of support springs 502 are located inside the I-shaped sealing gasket 501.

[0026] The snap-fit ​​rod 2 has two sets of snap-fit ​​interfaces inside. Both sets of plug-in rods 301 are plugged into the inside of the snap-fit ​​interfaces. The snap-fit ​​interfaces enable the plug-in rods 301 to snap into place, thereby limiting the rotor shaft body 4.

[0027] The outer side of the rotating shaft housing 1 is snapped with a mounting shell 6, and the inside of the rotor shaft body 4 is provided with a rotating rod 7. The rotating rod 7 serves to install the device.

[0028] Several sets of threaded holes are provided on one side of the rotor shaft body 4. Each set of threaded holes is threaded with a fixing bolt 8. The fixing bolt 8 serves to install the positioning shell 10.

[0029] A mounting plate 9 is threadedly connected to the outer side of several sets of fixing bolts 8, and a positioning shell 10 is fixedly connected to one side of several sets of mounting plates 9. The positioning shell 10 serves to protect the I-shaped sealing gasket 501.

[0030] Two sets of storage slots are provided on one side of the mounting shell 6. The outer side of the rotating rod 7 is fixedly connected to the limiting plate 11. The storage slots serve to install the sliding block 302.

[0031] Both sides of the rotor shaft body 4 are fixedly connected to connecting plates 12, and several sets of limiting blocks 13 are fixedly connected to one side of each of the two sets of connecting plates 12. The setting of the limiting blocks 13 plays the role of limiting the connecting parts.

[0032] In this invention, the working steps of the device are as follows:

[0033] First step: When in use, the I-shaped sealing gasket 501 is installed on the rotor shaft body 4. The support spring 502 can disperse the contact stress between the I-shaped sealing gasket 501 and the rotor shaft body 4, avoid excessive local wear, and thus extend the service life of the I-shaped sealing gasket 501. Secondly, the support spring 502 can provide continuous elastic force to the I-shaped sealing gasket 501, which not only ensures that the sealing gasket can fit tightly against the rotor shaft and the inner wall of the sealing cavity, but also automatically compensates for the gap changes caused by the wear of the sealing gasket or the axial movement of the rotor shaft, so that the device can effectively block the leakage path of lubricating oil and ensure the reliability and stability of the seal.

[0034] Second step: During installation, move the sliding block 302. The movement of the sliding block 302 causes the plug rod 301 to move. At this time, the return spring 303 is in a compressed state. Insert the device into the inside of the mounting shell 6, release the sliding block 302, and the return spring 303 causes the sliding block 302 to return to its original position. The plug rod 301 is inserted into the snap-fit ​​interface on one side of the snap-fit ​​rod 2, limiting the snap-fit ​​rod 2, so that the device can be quickly installed and disassembled.
