[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0030] Refer to Figure 1 Figure 3 An embodiment provided by the utility model: an impact-resistant self-aligning roller bearing, comprising a bearing body 1, which is a self-aligning roller bearing, and a protection mechanism is arranged outside the bearing body 1, the protection mechanism comprises a protection assembly and an auxiliary assembly, the protection assembly comprises a protective shell one 21, the protective shell one 21 is arranged at the right side of the bearing body 1, a protective shell two 22 is arranged at the left side of the protective shell one 21, and the protective shell one 21 and the protective shell two 22 jointly form an external protection barrier for the bearing body 1. During the operation of the equipment, the protective shell can resist the impact of various foreign matters from the outside world, prevent these factors from directly acting on the bearing body 1, thereby reducing the wear, corrosion and damage risk of the bearing caused by external factors, prolonging the service life of the bearing, and the protective shell one 21 and the protective shell two 22 are provided with two groups and are symmetrically arranged.
[0031] Further, the inner wall of the protective shell one 21 is provided with a buffer plate 23. When external impact force is transmitted to the protective shell, the buffer plate 23 first bears the impact energy. The buffer plate 23 is made of a material with good elastic and damping properties, such as rubber or a special polymer composite. The buffer plate 23 absorbs and disperses the impact force by its elastic deformation, converts the instantaneous high-intensity impact into a more moderate energy form, and avoids the direct transmission of the impact force to the bearing body 1, thereby effectively reducing the impact load peak borne by the bearing, protecting the internal structure of the bearing from damage, maintaining the precision and reliability of the bearing, and facilitating the installation and positioning of the buffer plate 23. The buffer plate 23 is provided with a fixing column 24 on the outside, and the protective shell one 21 is provided with a slot 25 on the inside. The fixing column 24 is inserted into the inner wall of the slot 25, and the fixing column 24 cooperates with the slot 25 to ensure that the buffer plate 23 can maintain a stable structural form when bearing impact, so that it can effectively play a buffering role according to the design requirements.
[0032] Referring to Figure 3 and Figure 4 , the auxiliary assembly includes a sliding block 31 slidingly connected to the inner wall of the two protective shells one 21, and the outer side of the protective shell one 21 penetrates the inner wall of the buffer plate 23. The sliding block 31 is attached to the outer side of the bearing body 1. During the operation of the equipment, when the bearing body 1 is subjected to vibration or slight impact, the sliding block 31 can slide relatively on the inner wall of the protective shell one 21 to press the compression spring 32, thereby assisting in buffering to a certain extent. The sliding block 31 and the protective shell one 21 are elastically connected by the compression spring 32. One end of the compression spring 32 is attached to the outer side of the sliding block 31, and the other end of the compression spring 32 is attached to the inner wall of the protective shell one 21. The initial state of the compression spring 32 is in a compressed state, which plays a buffering and adjusting role. When the sliding block 31 moves due to vibration or impact, the compression spring 32 can absorb and store part of the energy, and relieve the impact by its elastic deformation, so that the structure inside the protective shell can better adapt to the dynamic load changes of the outside world. When the impact disappears, the compression spring 32 releases the stored energy to push the sliding block 31 back to the initial position, restoring the balance state inside the protective shell, thereby further improving the protection effect of the protective mechanism on the bearing body 1 and enhancing the anti-impact performance and stability of the entire bearing under complex working conditions.
[0033] Further, the buffer plate 23 and the slot 25 are provided in multiple groups. Another group of buffer plate 23 and slot 25 are provided on the inner side of the protective shell two 22. The bearing body 1 is provided with a mounting groove 4 on the outer side, and the inner side of the protective shell one 21 and the protective shell two 22 is provided with a mounting plate 5. The mounting plate 5 is inserted into the inner wall of the mounting groove 4 to fix the protective shell one 21 and the protective shell two 22. The outer side of the buffer plate 23 is provided with an anti-skid strip on the side close to the bearing body 1 to increase the friction between the buffer plate 23 and the bearing body 1, preventing the buffer plate 23 from moving due to equipment vibration during normal operation.
[0034] Referring to Figure 2 And Figure 3 , the front side of the protective shell one 21 and the protective shell two 22 is provided with a disassembly assembly, the disassembly assembly includes a bolt one 61, two groups of protective shell one 21 are fixedly installed through the bolt one 61, the bolt one 61 is provided with multiple groups, multiple groups of bolt one 61 are fixedly installed on the inner wall of two groups of protective shell two 22, the bolt one 61 is used for fixing and connecting two groups of protective shell one 21 and two groups of protective shell two 22 together respectively, the protective shell one 21 and the protective shell two 22 are fixedly installed through the bolt two 62, the bolt two 62 is provided with multiple groups, multiple groups of bolt two 62 are respectively arranged on the upper and lower sides of the protective shell one 21 and the protective shell two 22, the protective shell one 21 and the protective shell two 22 are fixedly connected into a whole, the fastening force generated by tightening when installing these bolts ensures the connection tightness and stability between the protective shells, so that the protection mechanism can effectively play a protective role on the bearing body 1, when the bearing needs to be maintained, overhauled or replaced, the operator can conveniently and quickly disassemble the protective shell by loosening these bolts, so as to directly contact the bearing body 1 and perform corresponding operation, ensuring the firmness of the protective shell during normal use, and facilitating disassembly when necessary, improving the convenience and efficiency of equipment maintenance.
[0035] Working principle: when the equipment is subjected to external impact in use, the impact force first acts on the protective shell one 21 and the protective shell two 22, the protective shell preliminarily resists part of the impact energy and disperses the action range of the impact force by virtue of its structural strength and material properties, preventing it from directly concentrating on the bearing body 1.
[0036] At the same time, since the buffer plate 23 is made of a material with good elasticity and damping properties, it begins to deform elastically under the action of the impact force, converting the impact energy into elastic potential energy for absorption and storage, in this process, the deformation of the buffer plate 23 effectively disperses the impact force, avoiding excessive stress concentration of the impact force in the local area of the bearing body 1, while the buffer plate 23 is subjected to impact deformation, the slider 31 also slides relatively in the inner wall of the protective shell one 21 due to the vibration and pressure change caused by the impact, the sliding of the slider 31 further extrudes and compresses the compression spring 32, so that the compression spring 32 is further compressed and absorbs energy, further reducing the impact on the bearing body 1.
[0037] When the external impact ends, the buffer plate 23 gradually recovers to the original shape due to the elastic recovery properties of the material itself, releasing the previously absorbed and stored elastic potential energy, in this process, the buffer plate 23 releases the remaining small energy in a relatively mild form, avoiding the adverse effects of secondary impact or vibration on the bearing body 1.
[0038] At the same time, the compression spring 32 is also gradually recovered from the compressed state to the initial pre-compressed state, releasing the stored energy and pushing the slider 31 back to the initial position, so that the internal structure of the protective shell is restored to the balanced stable state, ensuring that the bearing body 1 can continue to operate normally in a stable environment, providing reliable protection for the continuous and stable operation of the equipment.
[0039] When it is necessary to maintain, overhaul or replace the bearing body 1, the operator can loosen the bolts 61 and 62 on the front side and upper and lower sides of the protective shell 1 and the protective shell 2, release the fastening connection between the protective shells, and then disassemble the protective shell 1 and the protective shell 2 from the outside of the bearing body 1 to directly expose the bearing body 1, so as to perform the corresponding maintenance operation, such as cleaning, checking the wear condition of the rollers and raceways, replacing the lubricating oil or damaged parts, etc. After completing the maintenance work, the protective shells are reinstalled and fastened in the reverse order, so that the bearing is restored to the protected state and continues to be used.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or equivalently replace some of the technical features, and any modification, equivalent replacement or improvement made within the spirit and principles of the present application shall be included in the protection scope of the present application.
