Description

Technical Field

[0001] The present invention relates to the technical field of adapter sleeves, and particularly to a flexible buffer adapter sleeve for preventing the outer wall from being extruded and deformed. Background Art

[0002] As a key connecting and fixing component in the mechanical and engineering fields, the adapter sleeve realizes the firm connection and fixing of rotating components such as bearings and shafts through its unique structure and design. This connection and fixing not only ensure the stability and reliability of the rotating components during operation, but also prevent equipment failures and safety accidents caused by loosening or falling off. The adapter sleeve also has certain adjustment and compensation functions. During the installation and commissioning of mechanical equipment, due to the influence of various factors, such as the slight bending of the shaft and the deviation of the bearing seat, etc., the clearance between the rotating component and the adapter sleeve may change. The adapter sleeve can compensate for these clearances to a certain extent through its elasticity and adjustability, thereby ensuring the stable operation of the rotating component. The adapter sleeve also has the advantages of simplifying installation and maintenance. Its structure is relatively simple, and the installation and disassembly are convenient, without the need for complex tools and equipment. At the same time, the adapter sleeve has a long service life and low maintenance cost, which can effectively reduce the operating cost of mechanical equipment.

[0003] Chinese Patent Publication No. CN106979248A discloses a new type of bearing adapter sleeve, including an adapter sleeve, a bearing, a locking nut, and a pin shaft. The threaded section is connected to the small-diameter end of the tapered section, and a relief groove is arranged along the circumferential direction at the intersection of the threaded section and the tapered section. One end of the adapter sleeve is provided with a tapered section, and the other end is provided with a threaded section. A locking nut is arranged on the relief groove, and it is of the same width as the relief groove and the connection position completely fits. A bearing is arranged on the tapered section, and the locking nut is connected to the bearing. A rotating shaft passing through the upper and lower ends of the whole is arranged in the middle of the adapter sleeve. First positioning holes are respectively arranged on both end faces of the pin shaft and are symmetrical about the rotating shaft. A plurality of threaded sections are arranged and extend to the intersection of the threaded section and the tapered section. The pin shaft and the bearing are connected by screws and extend outwards, enhancing the fastening effect, facilitating operation and use, accelerating operation, having high work efficiency, low cost, and being conducive to large-scale use in factories.

[0004] However, the existing devices have the following problems:

[0005] In the prior art, the adapter sleeve is usually made of rigid materials, with a relatively simple structure. It mainly consists of an outer ring and an inner ring. Through the cooperation of the inner ring with components such as bearings, the functions of connection and fixation are achieved. However, in the face of external pressure or extrusion, the outer wall is prone to deformation, resulting in changes in the size and shape of the adapter sleeve, thereby affecting its connection and fixation effects. At the same time, due to the mechanical installation method of the existing adapter sleeve, hard tools such as hammers need to be used for knocking during installation. This not only damages the adapter sleeve, destroys its integrity, causes it to deform, making it impossible to disassemble due to being too tight during disassembly, but also makes the adapter sleeve unable to be reused. Summary of the Invention

[0007] In view of the deficiencies of the prior art, the present invention provides a flexible buffer anti-extrusion deformation adapter sleeve for the outer wall, which has the advantages of being convenient for protecting the outer wall of the adapter sleeve and facilitating the installation and disassembly of components such as bearings. It solves the problems that the deformation of the adapter sleeve occurs due to the inconvenience of protecting the outer wall of the adapter sleeve and the inconvenience of installation and disassembly for workers.

[0021] (III) Beneficial effects

[0022] Compared with the prior art, the present invention provides a flexible buffer anti-extrusion deformation locking sleeve, which has the following beneficial effects:

[0023] 1. For this flexible buffer anti-extrusion deformation locking sleeve, through the setting of the protection component, the protection component is composed of a snap ring, a buffer spring, a protective ring and a buffer sleeve. This series of components work together to form an effective elastic buffer system. When external pressure acts on the locking sleeve, the buffer spring can absorb and disperse these pressures, preventing them from directly acting on the main structure of the locking sleeve, effectively solving the problem that the outer wall of the traditional locking sleeve is prone to deformation when facing external pressure or extrusion, thus greatly reducing the risk of outer wall deformation. This design not only protects the integrity of the locking sleeve, but also ensures the stability and reliability of the locking sleeve under various working conditions.

[0024] 2. The flexible buffer anti-extrusion deformation fixing sleeve, through the setting of the installation component, which is composed of multiple positioning plates, lead screws, limiting plates and anti-slip pads, realizes a more gentle and controllable installation method. Traditional fixing sleeves mostly adopt mechanical installation methods, often requiring the use of hard tools for knocking. This not only easily damages the fixing sleeve, but may also cause it to be unable to be disassembled smoothly due to deformation during use. With the installation component, the operator can easily complete the positioning and fixing of the fixing sleeve by adjusting the lead screw, without using hard tools, thus avoiding deformation and damage caused by knocking. At the same time, this installation method is also convenient for the disassembly and secondary use of the fixing sleeve, greatly reducing the maintenance cost and the difficulty of use. At the same time, this fixing sleeve also has excellent adaptability and compatibility. Its structural design is flexible and can be customized and adjusted according to different application scenarios and requirements. Whether it is for components such as bearings of different sizes, or for different installation environments and conditions, this fixing sleeve can provide a stable and reliable connection and fixing effect.

Specific embodiments

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1 to 8 , the present invention provides a flexible buffer anti-extrusion deformation fixing sleeve, which is applied to the scenarios of connecting and fixing rotating components such as bearings and shafts. In this embodiment, by improving the structure of the fixing sleeve, it has the advantages of preventing the outer wall from being extruded and deformed and facilitating the installation and disassembly of rotating components such as bearings and shafts by staff. Specifically, taking the fixing sleeve as an example, as a preferred solution in this embodiment, the fixing sleeve is specifically a flexible buffer anti-extrusion deformation fixing sleeve, which can play a role in protecting the outer wall of the fixing sleeve.

[0036] Please refer to Figures 1 to 8 , the present invention provides a technical solution: a flexible buffer anti-extrusion deformation fixing sleeve, which is mainly applied to the scenarios of connecting and fixing rotating components such as bearings and shafts.

[0037] It includes a locking bushing 1, a protection component 2 and an installation component 3, wherein:

[0038] The protection component 2 includes a snap ring 201, a buffer spring 202, a protection ring 203 and a buffer sleeve 204. The snap ring 201 is clamped on the outer surface of the locking bushing 1. The lower end of the buffer spring 202 is fixedly installed on the outer surface of the snap ring 201. The protection ring 203 is fixedly installed on the outer surface of the snap ring 201 through the buffer spring 202. The buffer sleeve 204 is fixedly connected to the outer surface of the protection ring 203;

[0039] The installation component 3 includes a plurality of positioning plates 301, lead screws 302, limiting plates 303 and anti-slip pads 304. The plurality of positioning plates 301 are all fixedly connected to the outer surface of the locking bushing 1. The side surfaces of the plurality of positioning plates 301 are all threadedly connected with lead screws 302 for adjustment. One end of the lead screw 302 is clamped with a limiting plate 303 for positioning. The outer surface of the limiting plate 303 is fixedly connected to the side surface of the anti-slip pad 304.

[0040] In this embodiment, through the settings of the locking bushing 1, the protection component 2 and the installation component 3, it is convenient for the operator to easily complete the positioning and fixing of the adapter sleeve, and play the role of installing and disassembling rotating components such as the bearing 9 and the shaft. At the same time, it is ensured that when the adapter sleeve is in use, the problem that the outer wall of the traditional adapter sleeve is prone to deformation when facing external pressure or extrusion is effectively solved, further improving the practicability of the flexible buffer anti-extrusion deformation adapter sleeve.

[0041] A positioning slot 4 is provided on the side surface of the locking bushing 1. The outer surface of the locking bushing 1 is provided with external threads. Through the setting of the slot 4, the slot 4 mainly provides positioning and fixing functions. When the adapter sleeve is installed on the shaft and fastened in a certain way, the slot 4 can cooperate with the corresponding structure on the shaft, so as to ensure the accurate positioning of the adapter sleeve and the components such as the bearing 9 connected thereto on the shaft. Through the setting of the external threads, a firm connection can be formed between the adapter sleeve and the shaft or other connecting components. This connection not only helps to prevent relative movement between the components, but also ensures the stability and reliability of the entire system. Through the screwing of the threads, the adapter sleeve can be closely attached to the shaft, so as to withstand various loads and vibrations.

[0042] A positioning ring 5 for positioning is threadedly connected to the outer surface of the locking bushing 1. A bearing 9 is clamped on the outer surface of the locking bushing 1. Through the setting of the ring 5, the ring 5 can disperse the pressure generated during threaded connection, preventing the surfaces of the connected parts such as the adapter sleeve and the shaft from being damaged due to excessive pressure. Especially in some high-precision or high-requirement machinery, it is crucial to protect the surface of the connected parts. At the same time, by increasing the contact area, the ring 5 can more effectively disperse the pressure and improve the stability of the connection.

[0043] A positioning hole 8 for limiting is provided on the outer surface of the ring 5. The inner side wall of the ring 5 is provided with internal threads. Through the setting of the hole 8, it can play a role in positioning the locking gasket 6 and the elastic piece 7, further playing a role in fixing the ring 5, which helps to improve the performance and reliability of the entire system.

[0044] The outer surface of the locking bushing 1 is clamped with a locking gasket 6 for fixing, and the outer surface of the locking gasket 6 is fixedly connected with a spring plate 7 for positioning. Through the arrangement of the locking gasket 6 and the spring plate 7, the locking gasket 6 can increase the friction between the tightening sleeve and the shaft, thereby preventing the tightening sleeve from loosening due to external factors such as vibration and impact, and can provide additional locking force after the tightening sleeve is installed in place to ensure that the tightening sleeve will not fall off or shift due to external force. At the same time, in the connection of some large structural parts, the locking gasket 6 can also compensate for the deformation caused by the force to a certain extent, and maintain the tightness of the connection. The spring plate 7 is elastic and can provide additional tightening force after the tightening sleeve is installed in place to ensure the firmness of the connection. The spring plate 7 can prevent the tightening sleeve from loosening due to external factors such as vibration and impact through its elastic deformation. At the same time, the spring plate 7 can adapt to the slight deformation between the tightening sleeve and the shaft due to thermal expansion and contraction or other reasons, thereby maintaining the stability of the connection.

[0045] A circular hole 10 for positioning is provided on the outer surface of the retaining ring 201, and the interior of the circular hole 10 is fixedly installed with the lower end of the buffer spring 202. The provision of the circular hole 10 allows the operator to more conveniently fix the buffer spring 202 on the outer surface of the retaining ring 201, further ensuring that the buffer spring 202 is more stable when subjected to pressure and that the buffer spring 202 will not bend, further ensuring the stability of the buffer spring 202, and the elastic coefficient of the buffer spring 202 can fully achieve the above-mentioned effect.

[0046] A spring column 11 for buffering is fixedly installed on the side of the protective ring 203, and one end of the spring column 11 is detachably connected to a retaining ring 12 for positioning. Through the arrangement of the spring column 11 and the retaining ring 12, after the bearing 9 is installed, the retaining ring 12 can be used to limit and fix the bearing 9. The spring column 11 uses its elastic characteristics to provide a certain elastic support for the bearing 9. This support not only helps to position and align the bearing 9 during the installation process, but also can absorb and buffer external vibrations and impacts during operation. At the same time, the spring column 11 is elastic, so they can adapt to slight deformations caused by thermal expansion and contraction or other reasons. This adaptability helps to maintain a close fit between the bearing 9 and the shaft, thereby protecting the bearing 9 from damage, further preventing the bearing 9 from loosening and shaking during use, and further ensuring the overall stability of the clamping sleeve.

[0047] One end of the spring post 11 is fixedly installed with a connecting disk 13, and the other end of the spring post 11 is fixedly connected with a limiting rod 14 for positioning. Through the settings of the disk 13 and the limiting rod 14, the retaining ring 12 can be stably fixed at one end of the spring post 11, further ensuring that when the retaining ring 12 is used to limit and fix the bearing 9, the situation of the retaining ring 12 falling off is prevented. At the same time, through the limiting rod 14, the spring post 11 can be limited, preventing the spring post 11 from bursting open.

[0048] The side surface of the disk 13 is threadedly connected with a threaded head 15 for fixation. The threaded head 15 penetrates through the side surface of the disk 13 and is threadedly connected to the side surface of the retaining ring 12. Through the setting of the threaded head 15, it is further ensured that the operator can more conveniently fix the retaining ring 12 at one end of the spring post 11, and further ensures that when fixing and limiting the bearing 9, the situation of the retaining ring 12 loosening during the fixation of the bearing 9 is prevented.

[0049] The other end of the lead screw 302 is fixedly connected with a handle 16 for rotation. The outer surface of the handle 16 is provided with anti-slip threads. Through the settings of the handle 16 and the anti-slip threads, the handle 16 provides a part that is convenient for holding and operating, enabling the operator to easily rotate the lead screw 302, thereby realizing the required mechanical movement or adjustment. The anti-slip threads can increase the roughness of the outer surface of the handle 16, thereby improving the stability when the operator holds it. Even in a wet or greasy environment, the anti-slip threads can effectively prevent the hand from slipping or falling off.

[0050] In summary, when the flexible buffer anti-extrusion deformation locking sleeve is in use:

[0051] 1. First, snap the snap ring 201 onto a predetermined position on the outer surface of the locking bushing 1, then the lower end of the buffer spring 202 can be fixedly installed on the outer surface of the snap ring 201. After fixedly installing the protective ring 203 on the outer surface of the snap ring 201 through the buffer spring 202, the buffer sleeve 204 can be fixed on the outer surface of the protective ring 203;

[0052] 2. Second, fixedly connect a plurality of positioning plates 301 to the outer surface of the locking bushing 1, threadedly connect the lead screw 302 to the side surfaces of the plurality of positioning plates 301, ensure that the lead screw 302 can rotate freely and adjust its length, and snap the limiting plate 303 onto one end of the lead screw 302 to ensure that the limiting plate 303 can move as the lead screw 302 rotates;

[0053] 3. Then, snap the bearing 9 onto the outer surface of the locking bushing 1 to ensure that the bearing 9 can rotate freely. Install the locking gasket 6 and the elastic piece 7 on the outer surface of the locking bushing 1 to increase the stability of the ring 5 and prevent loosening, and threadedly connect the ring 5 to the outer surface of the locking bushing 1 for further positioning;

[0054] 4. Finally, rotate the handle 16 to adjust the position of the limit plate 303 through the lead screw 302, so as to adjust the positions of the snap ring 201 and the protective ring 203, and the spring post 11 and the retaining ring 12 play a role in fixing and limiting the bearing 9.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
