Description

Technical Field

[0001] This utility model relates to the field of locking sleeve technology, specifically a heavy-duty mechanical anti-deformation locking sleeve. Background Technology

[0002] The adapter sleeve is the most commonly used component for positioning bearings with tapered bores on cylindrical shafts. This type of sleeve can be used on both plain shafts and stepped shafts. It consists of parts such as adapter bushing, lock nut, and lock washer. Adapter sleeves with lock nut and lock washer can only be interchanged as a complete set; parts from different sources cannot be interchanged.

[0003] Traditional adapter sleeves, subjected to heavy loads and high-speed operation for extended periods, are susceptible to deformation due to the large axial and radial forces they must withstand during operation. The limited structural strength of the adapter sleeve makes it difficult to effectively resist these external forces. This deformation not only affects the tightness of the connection between the adapter sleeve and its mating components but also reduces the operational stability and reliability of the entire mechanical equipment. Furthermore, the inner surface of existing adapter sleeves is typically flat, which can easily lead to relative slippage when connecting to rotating shafts. This exacerbates component wear and consequently shortens the service life of the adapter sleeve. Utility Model Content

[0004] The purpose of this utility model is to provide a heavy-duty mechanical anti-deformation locking sleeve, which solves the problems of easy deformation and relative slippage caused by insufficient strength and friction of traditional locking sleeves.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a heavy-duty mechanical anti-deformation locking sleeve, including a locking sleeve body. A threaded groove is formed on the outer surface of one end of the locking sleeve body. A plurality of connecting grooves are formed on one end of the locking sleeve body. A plurality of mounting grooves are formed on the circumferential side of the locking sleeve body. Reinforcing ribs are fixedly installed inside each of the mounting grooves. A wear-resistant component is installed inside the locking sleeve body. The connecting end of the wear-resistant component is threadedly connected to the connecting groove.

[0007] Furthermore, the wear-resistant component includes a reinforcing sleeve, which is inserted into the interior of the locking sleeve body. A limiting plate is fixedly installed at one end of the reinforcing sleeve, and the limiting plate abuts against one end of the locking sleeve body.

[0008] Furthermore, the inner surface of the reinforcing sleeve is provided with a high-friction layer.

[0009] Furthermore, the limiting plate has several through holes inside, which are connected to the connecting groove, and each through hole has a misalignment groove at one end.

[0010] Furthermore, each of the through holes is provided with a locking bolt, which is connected to the internal thread of the through hole and the connecting groove, with one end of the locking bolt abutting against the inside of the misalignment groove.

[0011] Furthermore, the high-friction layer is made of a ceramic particle coating.

[0012] This utility model has the following beneficial effects:

[0013] (1) When the adapter sleeve needs to be installed on the corresponding shaft component, the reinforcing sleeve of the wear-resistant component is first inserted into the inside of the adapter sleeve body. At this time, the limiting plate abuts against one end of the adapter sleeve body to achieve initial positioning and limiting. The locking bolt passes through the through hole on the limiting plate. Since the through hole is connected to the connecting groove at one end of the adapter sleeve body, the locking bolt can be connected to the connecting groove through the thread. During the tightening process of the locking bolt, one end will abut against the inside of the misalignment groove. As it is tightened continuously, the locking bolt will exert force on the limiting plate and the reinforcing sleeve. A strong axial tensile force is generated, which forms a stable connection between the wear-resistant component and the adapter sleeve body, thus completing the installation of the wear-resistant component. When the adapter sleeve body is in use, the reinforcing sleeve can prevent the adapter sleeve body from deforming. At the same time, during mechanical operation, the high-friction layer on the inner surface of the reinforcing sleeve can effectively increase the friction between it and the mating parts. The high-friction layer of ceramic particle coating material, with its good friction performance, ensures the stability of the adapter sleeve under long-term heavy load, high speed and other complex working conditions, improves the deformation resistance and increases the connection stability.

[0014] (2) The mounting grooves provided on the periphery of the locking sleeve body and the reinforcing ribs fixedly installed inside the mounting grooves are to enhance the overall structural strength of the locking sleeve, so that it can better resist the action of complex external forces, maintain the stability of the structure, and ensure that it will not fail due to deformation under heavy load conditions, thereby further improving the deformation resistance and enhancing the overall safety and stability of heavy-duty machinery.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 As shown, this utility model is a heavy-duty mechanical anti-deformation fastening sleeve, including a fastening sleeve body 1. A threaded groove 101 is opened on the outer surface of one end of the fastening sleeve body 1. A plurality of connecting grooves 102 are opened on one end of the fastening sleeve body 1. A plurality of mounting grooves 2 are opened on the circumferential side of the fastening sleeve body 1. A reinforcing rib 3 is fixedly installed inside the mounting groove 2. A wear-resistant component 4 is installed inside the fastening sleeve body 1. The connecting end of the wear-resistant component 4 is threadedly connected to the connecting groove 102.

[0025] The mounting grooves 2 and the reinforcing ribs 3 fixedly installed inside the mounting grooves 2 on the side of the locking sleeve body 1 are designed to enhance the overall structural strength of the locking sleeve, enabling it to better resist the action of complex external forces, maintain structural stability, and ensure that it will not fail due to deformation under heavy load conditions. This further improves its resistance to deformation and enhances the overall safety and stability of heavy-duty machinery.

[0026] The wear-resistant component 4 includes a reinforcing sleeve 401, which is inserted into the inside of the locking sleeve body 1. A limiting plate 402 is fixedly installed at one end of the reinforcing sleeve 401, and the limiting plate 402 abuts against one end of the locking sleeve body 1.

[0027] The inner surface of the reinforcing sleeve 401 is provided with a high-friction layer 403;

[0028] The limiting plate 402 has several through holes 404 inside, which are connected to the connecting groove 102. One end of each through hole 404 has a misalignment groove 405.

[0029] Locking bolts 406 are provided inside the through holes 404. The locking bolts 406 are connected to the internal threads of the connecting groove 102 through the through holes 404. One end of the locking bolts 406 abuts against the inside of the misalignment groove 405.

[0030] The high-friction layer 403 is made of ceramic particle coating;

[0031] When the adapter sleeve needs to be installed on the corresponding shaft component, the reinforcing sleeve 401 of the wear-resistant component 4 is first inserted into the inside of the adapter sleeve body 1. At this time, the limiting plate 402 abuts against one end of the adapter sleeve body 1 to achieve initial positioning and limiting. The locking bolt 406 passes through the through hole 404 on the limiting plate 402. Since the through hole 404 is connected to the connecting groove 102 at one end of the adapter sleeve body 1, the locking bolt 406 can be connected to the connecting groove 102 through threads. During the tightening process of the locking bolt 406, one end will abut against the inside of the misalignment groove 405. As it is continuously tightened, the locking bolt 406 will press against the limiting plate. The 402 and the reinforcing sleeve 401 generate a strong axial tensile force, which makes the wear-resistant component 4 and the locking sleeve body 1 form a stable connection, thus completing the installation of the wear-resistant component 4. When the locking sleeve body 1 is in use, the reinforcing sleeve 401 can prevent the locking sleeve body 1 from deforming. At the same time, during mechanical operation, the high-friction layer 403 on the inner surface of the reinforcing sleeve 401 can effectively increase the friction between it and the mating parts. The high-friction layer 403 with ceramic particle coating material has good friction performance, which ensures the stability of the locking sleeve under long-term heavy load, high speed and other complex working conditions, improves the deformation resistance and increases the connection stability.

[0032] In use, when the adapter sleeve needs to be installed on the corresponding shaft component, the reinforcing sleeve 401 of the wear-resistant component 4 is first inserted into the inside of the adapter sleeve body 1. At this time, the limiting plate 402 abuts against one end of the adapter sleeve body 1 to achieve initial positioning and limiting. The locking bolt 406 passes through the through hole 404 on the limiting plate 402. Since the through hole 404 is connected to the connecting groove 102 at one end of the adapter sleeve body 1, the locking bolt 406 can be connected to the connecting groove 102 through threads. During the tightening process of the locking bolt 406, one end will abut against the inside of the misalignment groove 405. As it is continuously tightened, the locking bolt 406 will... The limiting plate 402 and the reinforcing sleeve 401 generate a strong axial tensile force, which makes the wear-resistant component 4 and the locking sleeve body 1 form a stable connection, thus completing the installation of the wear-resistant component 4. When the locking sleeve body 1 is in use, the reinforcing sleeve 401 can prevent the locking sleeve body 1 from deforming. At the same time, during mechanical operation, the high-friction layer 403 on the inner surface of the reinforcing sleeve 401 can effectively increase the friction between it and the mating parts. The high-friction layer 403 with ceramic particle coating material has good friction performance, which ensures the stability of the locking sleeve under long-term heavy load, high speed and other complex working conditions, improves the deformation resistance and increases the connection stability.

[0033] The mounting grooves 2 and the reinforcing ribs 3 fixedly installed inside the mounting grooves 2 on the side of the locking sleeve body 1 are designed to enhance the overall structural strength of the locking sleeve, enabling it to better resist the action of complex external forces, maintain structural stability, and ensure that it will not fail due to deformation under heavy load conditions. This further improves its resistance to deformation and enhances the overall safety and stability of heavy-duty machinery.
