[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The taper sleeve body is made of high-strength wear-resistant alloy, and the elastic inner layer is made of elastic memory alloy. This design can pre-deform the taper sleeve and the elastic inner layer by heating them during installation. When subjected to external impact or temperature changes, the clamping force can be adjusted adaptively to effectively prevent loosening. An anti-slip component is provided at the right end of the taper sleeve to prevent the large nut from falling off and loosening from the taper sleeve. A tightening component is provided at the left end of the taper sleeve to tighten the taper sleeve and enhance the connection stability between the taper sleeve, the optical axis and the bearing. 2. The elastic body is provided to increase the contact surface between the elastic inner layer and the optical axis, and the elastic force of the elastic body itself can be used to press the optical axis. Because there is an avoidance groove corresponding to the elastic body on the elastic inner layer, when the elastic inner layer is sleeved on the optical axis, the elastic inner layer can be forced to be pressed into the avoidance groove to ensure that the elastic inner layer can be sleeved on the optical axis. Lubricating liquid is added to the elastic body. When the elastic body is pressed, the lubricating liquid in the elastic body can flow out from the liquid permeable hole to reduce the friction between the elastic body and the optical axis, so that it is more labor-saving to sleeve the elastic inner layer on the optical axis. 3. When vibration or other external force interference occurs during the operation of the equipment, the large nut is at risk of loosening and falling out to the right. The internal thread sleeve is arranged at the right end of the tapered sleeve through the thread sleeve, which plays the role of the first line of defense and limits the axial displacement of the large nut. At the same time, the telescopic rod installed in the mounting hole extends into the annular groove, and the left end of the compression spring is pressed on the right side of the large nut, further strengthening the restriction on the large nut. The compression spring will continue to exert a leftward elastic force, so that the large nut is always under a leftward pressure. Even if the large nut has a tendency to move to the right in a vibrating environment, the elastic force of the compression spring will prevent it; 4. When the mounting ring moves to the right, the tightening block will generate an oblique force in the slot. This oblique force can be decomposed into axial and radial components. The axial component causes the tapered sleeve to be tightened to the left, thereby applying axial force to the tapered sleeve from the left and right sides with the large nut to ensure that the axial position of the tapered sleeve is fixed, thereby ensuring accurate axial positioning of the bearing. During the operation of the equipment, the tightening component continuously provides axial tightening force to prevent the tapered sleeve from axial displacement due to the axial force.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Embodiment 1 See also Figure 1-Figure 5The present invention provides a technical solution: a reinforced clamping sleeve, comprising a bearing 1 and a tapered sleeve 2, wherein the bearing 1 is sleeved on the tapered sleeve 2, a large nut 4 is provided on the right end thread sleeve of the tapered sleeve 2, a clamp 3 is provided on the sliding sleeve of the outer wall of the tapered sleeve 2, the clamp 3 is pressed on the inner wheel of the bearing 1, an elastic inner layer 7 is fixedly installed on the inner wall of the tapered sleeve 2, a disconnecting groove 201 is provided on the outer walls of the tapered sleeve 2 and the elastic inner layer 7, a clamping groove 202 is provided on the outer walls of the tapered sleeve 2 and the elastic inner layer 7, the disconnecting groove 201 is communicated with the clamping groove 202, an integrally formed positioning protrusion 301 is provided on the inner side of the clamp 3, an integrally formed anti-slip protrusion 302 is provided on the outer side of the clamp 3, the positioning protrusion 301 is inserted into the clamping groove 202, and an anti-slip protrusion 302 is provided on the outer wall of the large nut 4 The anti-slip groove 401, the anti-slip protrusion 302 is bent and inserted into the anti-slip groove 401, the right end of the tapered sleeve 2 is provided with an anti-slip component 5, the left end of the tapered sleeve 2 is provided with a tightening component 6, the tapered sleeve 2 body is made of high-strength wear-resistant alloy, and the elastic inner layer 7 is made of elastic memory alloy. This design can be pre-deformed by heating the tapered sleeve 2 and the elastic inner layer 7 during installation. When subjected to external force impact or temperature changes, the clamping force can be adaptively adjusted to effectively prevent loosening. The anti-slip component 5 is provided at the right end of the tapered sleeve 2 to prevent the large nut 4 from falling off and loosening from the tapered sleeve 2, and the tightening component 6 is provided at the left end of the tapered sleeve 2 to tighten the tapered sleeve 2, thereby enhancing the connection stability between the tapered sleeve 2 and the optical axis and the bearing 1; An elastic body 8 is integrally formed on the inner side of the elastic inner layer 7. The interior of the elastic body 8 is hollow. An escape groove is provided at the connection between the elastic inner layer 7 and the elastic body 8, and the inner diameter of the escape groove is consistent with the inner diameter of the elastic body 8. A liquid permeable hole 9 is provided on the outer wall of the elastic body 8 on the side facing away from the elastic inner layer 7. The elastic body 8 is provided to increase the contact surface between the elastic inner layer 7 and the optical axis. At the same time, the elastic force of the elastic body 8 itself can be used to press the optical axis. Because the elastic inner layer 7 has an escape groove corresponding to the elastic body 8, when the elastic inner layer 7 is sleeved on the optical axis, the elastic inner layer 7 can be forced to be pressed into the escape groove to ensure that the elastic inner layer 7 can be sleeved on the optical axis. Lubricating liquid is added to the elastic body 8. When the elastic body 8 is pressed, the lubricating liquid in the elastic body 8 can flow out from the liquid permeable hole 9, thereby reducing the friction between the elastic body 8 and the optical axis, making it easier to sleeve the elastic inner layer 7 on the optical axis. The outer wall of the tapered sleeve 2 is fixedly provided with positioning dots 10, and there are multiple positioning dots 10, which are distributed in a circular array on the tapered sleeve 2. The positioning dots 10 are staggered with the disconnection grooves 201. During the operation of the adapter sleeve, the positioning dots 10 can play the role of reinforcing ribs. When the adapter sleeve is subjected to radial force or axial force, these positioning dots 10 can disperse stress and avoid stress concentration at the disconnection grooves 201. For example, when the bearing 1 rotates at high speed to generate centrifugal force or the equipment is subjected to external impact, the positioning dots 10 help maintain the overall shape of the tapered sleeve 2, prevent deformation or damage caused by excessive local stress, thereby enhancing the stability of the adapter sleeve structure. In addition, since the positioning dots 10 are staggered with the disconnection grooves 201, they will not interfere with the cooperation between the positioning protrusion 301 on the clamp 3 and the clamping groove 202; An integrally formed metal sheet 11 is provided on the outer wall of the clamp 3 facing the bearing 1, and a rubber pad 12 is fixedly installed on the outer wall of the clamp 3 facing the bearing 1. An avoidance groove is provided on the rubber pad 12, and the metal sheet 11 passes through the avoidance groove on the rubber pad 12. The thickness of the rubber pad 12 is greater than that of the metal sheet 11. The thickness of the rubber pad 12 is greater than that of the metal sheet 11, which enables the rubber pad 12 to play a major buffering role during the operation of the adapter sleeve. When the equipment generates vibration during operation or the bearing 1 is subjected to axial impact, the rubber pad 12 can effectively absorb and buffer these impact forces. The softness of the rubber pad 12 The wear caused by direct contact between the clamp 3 and the bearing 1 can be avoided, ensuring that the accuracy and performance of the bearing 1 are not affected. The metal sheet 11 passes through the avoidance groove of the rubber pad 12. When the adapter sleeve is subjected to axial force, the metal sheet 11 can serve as a rigid support structure, which can more effectively transfer the axial force to the rubber pad 12, and then evenly distribute it to the inner wheel of the bearing 1 through the rubber pad 12. This design avoids the concentration of axial force in the local area of ​​the rubber pad 12, ensures the uniformity of force transmission, enables the bearing 1 to work under a more reasonable stress state, and reduces the failure of the bearing 1 caused by excessive local force.

[0020] Working principle: When in use, the bearing 1 is sleeved on the tapered sleeve 2, and the tapered surface of the tapered sleeve 2 cooperates with the inner ring of the bearing 1. When installing, place the bearing 1 at a suitable position on the tapered sleeve 2. Due to the existence of the taper, when the large nut 4 is turned to the right, the large nut 4 applies an axial force to the right on the tapered sleeve 2. This force makes the tapered surface of the tapered sleeve 2 in close contact with the inner ring of the bearing 1, thereby realizing the axial positioning of the bearing 1. When the shaft is installed with the tapered sleeve 2, the shaft may have a certain dimensional tolerance or produce a slight deformation during operation. The elastomer 8 can adapt to the size change of the shaft through its own elastic deformation, providing a good clamping force. The avoidance groove at the connection between the elastic inner layer 7 and the elastomer 8 ensures the space requirement of the elastomer 8 during the deformation process, and the avoidance groove can effectively prevent the elastomer 8 from being deformed. The inner diameter of the groove is consistent with the inner diameter of the elastomer 8, so that the deformation of the elastomer 8 is more uniform. The lubricant is injected through the liquid permeable hole 9 to make the friction between the shaft and the elastomer 8 smoother. At the same time, the lubricant also helps to further improve the adaptability of the elastomer 8. After the large nut 4 is tightened, the anti-slip protrusion 302 on the outside of the clamp 3 is bent and inserted into the anti-slip groove 401 on the outer wall of the large nut 4, fixing the position of the clamp 3 and enhancing the tightness of the entire structure. The anti-slip component 5 at the right end of the tapered sleeve 2 and the tightening component 6 at the left end further enhance the stability of the structure. The anti-slip component 5 can prevent the large nut 4 from slipping out to the right, and the tightening component 6 provides supporting force on the left side, making the axial position of the tapered sleeve 2 more stable, avoiding loosening between components due to excessive axial force.

The interior of the elastic body 8 is hollow. An escape groove is provided at the connection between the elastic inner layer 7 and the elastic body 8. The inner diameter of the escape groove is consistent with the inner diameter of the elastic body 8. A liquid permeable hole 9 is provided on the outer wall of the elastic body 8 on the side facing away from the elastic inner layer 7. The outer wall of the tapered sleeve 2 is fixedly provided with a positioning dot 10, and a plurality of positioning dots 10 are provided, and a circumferential array is distributed on the tapered sleeve 2, and the positioning dots 10 are staggered with the disconnection groove 201; An integrally formed metal sheet 11 is provided on the outer wall of the clamp 3 facing the bearing 1, and a rubber pad 12 is fixedly installed on the outer wall of the clamp 3 facing the bearing 1. The rubber pad 12 is provided with an avoidance groove, and the metal sheet 11 passes through the avoidance groove on the rubber pad 12. The thickness of the rubber pad 12 is greater than that of the metal sheet 11. The anti-slip component 5 includes an internal threaded sleeve 501 and an annular groove 502. The internal threaded sleeve 501 is threadedly sleeved on the right end of the tapered sleeve 2. The annular groove 502 is provided on the right outer wall of the large nut 4. A mounting hole 503 is provided on the left outer wall of the internal threaded sleeve 501. A telescopic rod 504 is fixedly installed on the inner wall of the mounting hole 503. The left end of the telescopic rod 504 extends into the annular groove 502. A compression spring 505 is fixedly installed on the inner wall of the mounting hole 503. The left end of the compression spring 505 presses on the right side surface of the large nut 4. When vibration or other external force interference occurs during the operation of the equipment, the large nut 4 is at risk of loosening and falling off to the right. The internal threaded sleeve 501 is threadedly sleeved on the right end of the tapered sleeve 2, which acts as the first line of defense to limit the axial displacement of the large nut 4. At the same time, the telescopic rod 504 installed in the mounting hole 503 extends into the annular groove 502, and the left end of the compression spring 505 presses On the right side of the large nut 4, the restriction on the large nut 4 is further strengthened, and the compression spring 505 will continue to apply a leftward elastic force, so that the large nut 4 is always subjected to a leftward pressure. Even if the large nut 4 has a tendency to move to the right under a vibration environment, the elastic force of the compression spring 505 will prevent it, ensuring that the large nut 4 will not easily fall off from the tapered sleeve 2, and the telescopic rod 504 can limit the displacement of the large nut 4 while ensuring the stability of the structure during the spring expansion and contraction process, and prevent the large nut 4 from rotating in the circumferential direction, thereby enhancing the reliability of the entire fixing sleeve structure. The combination of the telescopic rod 504 and the compression spring 505 can be dynamically adjusted according to the actual position and force conditions of the large nut 4. When the large nut 4 is subjected to forces of different directions and sizes, the compression spring 505 can change its compression degree according to the size and direction of the force, thereby maintaining a stable constraint on the large nut 4. A clamping convex ring 13 is fixedly installed on the inner side of the internal threaded sleeve 501, and the clamping convex ring 13 is inserted into the tapered sleeve 2, and the clamping convex ring 13 is tightly attached to the inner wall of the tapered sleeve 2. A rubber ring 14 is fixedly installed in the gap between the clamping convex ring 13 and the internal threaded sleeve 501, and the rubber ring 14 is pressed on the right end face of the tapered sleeve 2. The rubber ring 14 is pressed in the gap between the clamping convex ring 13 and the internal threaded sleeve 501, and is pressed on the right end face of the tapered sleeve 2. This design can effectively prevent external dust, moisture, impurities, etc. from entering the elastic inner layer 7, and the clamping convex ring 13 Inserted into the tapered sleeve 2 and tightly attached to the inner wall of the tapered sleeve 2, when the internal threaded sleeve 501 is fixed to the right end of the tapered sleeve 2 by threaded connection, the pressing convex ring 13 will generate a radial pressure on the tapered sleeve 2, and this pressure will increase the friction between the tapered sleeve 2 and the internal threaded sleeve 501 to a certain extent, thereby enhancing the tightening force in the axial direction. During the operation of the equipment, even if it is subjected to the axial force, this friction can effectively prevent the internal threaded sleeve 501 from loosening, further ensuring that the large nut 4 will not generate axial displacement due to the loosening of the internal threaded sleeve 501; There are five mounting holes 503, and the circumferential array is distributed on the internal thread sleeve 501, so that the compression spring 505 can evenly apply leftward pressure to the large nut 4 from multiple directions. When the equipment generates vibration or is subjected to external force, this evenly distributed pressure can better balance the force on the large nut 4 and prevent the large nut 4 from tilting or shifting in the circumferential direction. For example, in a rotating device, the large nut 4 may be subjected to centrifugal force and tangential force. The compression spring 505 distributed in the circumferential array can effectively offset these forces and maintain the stability of the large nut 4, thereby enhancing the reliability of the entire fastening sleeve structure. The compression spring 505 is made of magnetic material and has a certain self-positioning function during the installation process. When it is close to the large nut 4 or the tapered sleeve 2, the magnetic adsorption force can help the compression spring 505 quickly and accurately align the installation position, which is convenient for the operator to install. At the same time, during disassembly and maintenance, magnetic adsorption can also prevent the spring from falling easily, making it easy to recover and reinstall, thereby improving the convenience of operation.

[0022] Working principle: When in use, first thread the internal thread sleeve 501 onto the right end of the tapered sleeve 2. At this time, due to the threaded connection between the internal thread sleeve 501 and the tapered sleeve 2, the internal thread sleeve 501 begins to move to the right. When the internal thread sleeve 501 approaches the large nut 4, the left end of the telescopic rod 504 in the mounting hole 503 gradually approaches the annular groove 502. As the internal thread sleeve 501 continues to be tightened, the telescopic rod 504 will be inserted into the annular groove 502. At the same time, the compression spring 505 will be compressed. The compression spring 505 will generate a leftward elastic force during the compression process. An elastic force will act on the right side of the large nut 4. This pre-tightening force constrains the large nut 4 to the left after initial installation, preventing it from easily moving to the right due to vibration or other factors during the operation of the equipment. When the equipment starts to run, the clamping sleeve will be subjected to various forces, including axial force, radial force and impact force generated by vibration, etc. Under the action of these forces, the large nut 4 may tend to loosen and come out to the right. Due to the presence of the compression spring 505, it continuously applies a leftward elastic force to the large nut 4, so that the large nut 4 always remains in a compressed state.

The slot 604 is provided on the inner wall of the left end of the tapered sleeve 2. A tightening block 603 is fixedly mounted on the right outer wall of the mounting ring 601. The tightening block 603 is inserted into the slot 604. The slot 604 is inclined along the inner wall of the tapered sleeve 2. The thickness of the tightening block 603 is greater than the depth of the slot 604. The mounting ring 601 and the compression sleeve 60 2 is provided with a notch groove connected to the disconnect groove 201. When the mounting ring 601 moves to the right, the tightening block 603 will generate an oblique force in the slot 604. This oblique force can be decomposed into axial and radial components. The axial component causes the taper sleeve 2 to be tightened to the left, thereby exerting an axial force on the taper sleeve 2 from the left and right sides with the large nut 4 to ensure that the axial position of the taper sleeve 2 is fixed, thereby ensuring the accurate axial positioning of the bearing 1. During the operation of the equipment, the tightening component 6 continuously provides an axial tightening force to prevent The tapered sleeve 2 undergoes axial displacement due to the axial force. This stable axial positioning is crucial to ensure the normal operation of the bearing and the stability of the entire adapter sleeve structure. The notch grooves connected to the disconnect grooves 201 provided on the mounting ring 601 and the clamping sleeve 602 enable the entire adapter sleeve to better adapt to deformation in structure. When the tapered sleeve 2 undergoes slight radial or axial deformation due to various reasons, the disconnect grooves 201 and the notch grooves can provide a certain deformation space to avoid damage to the structure due to excessive local stress, thereby ensuring the structural integrity of the adapter sleeve. The clamping sleeve 602 is movably mounted on the left end of the tapered sleeve 2. This movably mounted arrangement enables the clamping sleeve 602 to adapt to the radial deformation of the tapered sleeve 2 within a certain range. For example, when the fit between the shaft and the tapered sleeve 2 undergoes slight changes due to wear, temperature changes and other factors, the clamping sleeve 602 can move with the radial changes of the tapered sleeve 2 to ensure close contact with the tapered sleeve 2, while maintaining the axial tightening effect on the tapered sleeve 2 through the mounting ring 601 and the tightening block 603. There are multiple tightening blocks 603 and slots 604, and the tightening blocks 603 and slots 604 correspond to each other one by one, so that the axial tightening force can be evenly distributed on the left end of the tapered sleeve 2. When the mounting ring 601 pushes the tightening block 603 to the right to enter the slot 604, each tightening block 603 will generate an axial component force, which is evenly distributed in the circumferential direction, avoiding the local stress concentration phenomenon caused by single-point tightening, so that the tapered sleeve 2 can be evenly subjected to the left tightening force in the circumferential direction, thereby ensuring the stable positioning of the tapered sleeve 2 in the axial direction; A rubber ring 15 is fixedly installed on the right outer wall of the clamping sleeve 602, and a positioning groove 16 is opened on the outer wall of the clamping sleeve 602. The rubber ring 15 is pressed on the inner wheel of the bearing 1. The rubber ring 15 is pressed on the inner wheel of the bearing 1 to increase the friction between the clamping sleeve 602 and the inner wheel of the bearing 1. In the axial direction, this friction helps to further fix the position of the bearing 1, and the auxiliary pressing component 6 and the large nut 4 perform axial positioning of the bearing 1. Especially during the operation of the equipment, when the bearing 1 is subjected to axial force, the friction generated by the rubber ring 15 can work together with other axial positioning components to better limit the axial movement of the bearing 1 and ensure the axial position stability of the bearing 1. The positioning groove 16 on the outer wall of the clamping sleeve 602 can be used to install other auxiliary positioning components or mark the position of the component, and the rubber ring 15 can also play a sealing role to a certain extent to prevent external dust, impurities, etc. from entering the matching area between the bearing 1 and the adapter sleeve, which is very important for keeping the bearing 1 clean and in a normal working environment, because the entry of impurities may cause problems such as increased wear and poor lubrication of the bearing 1.

[0024] Working principle: When in use, during the installation process, the mounting ring 601 is sleeved on the left end of the tapered sleeve 2, and the tightening block 603 is inserted into the inclined slot 604. Since the thickness of the tightening block 603 is greater than the depth of the slot 604, when the mounting ring 601 moves to the right, the tightening block 603 will generate an oblique force in the slot 604. This oblique force can be decomposed into axial and radial components. The axial component causes the tapered sleeve 2 to be tightened to the left, thereby applying axial force to the tapered sleeve 2 from the left and right sides with the large nut 4 to ensure that the axial position of the tapered sleeve 2 is fixed, thereby ensuring the accurate axial positioning of the bearing 1. During the operation of the equipment, the tightening component 6 continuously provides axial tightening force to prevent the tapered sleeve 2 from axial displacement due to the axial force. This stable axial positioning is crucial to ensure the normal operation of the bearing and the stability of the entire clamping sleeve structure.
