Description

Technical Field

[0001] This utility model relates to the field of roller shafts, and in particular to a roller shaft reinforcing connector. Background Technology

[0002] In industrial production, roller shafts, as core transmission components of equipment for conveying, crushing, and transporting, are widely used in various industries such as metallurgy, papermaking, printing, logistics, and machining. Their operational stability directly determines the operating efficiency and product quality of the entire production line. The connection between the roller shaft and the main body of the equipment or other transmission components, as a key node for force transmission, is a core link affecting the overall service life and safety performance of the roller shaft.

[0003] Currently, most roller shaft connectors on the market adopt traditional one-piece casting structures or simple bolt fastening structures. In practical applications, these connectors generally suffer from insufficient strength and poor bending resistance. When the roller shaft is under high-speed rotation, heavy-load transmission, or frequent start-stop conditions, it is very easy to develop fatigue cracks due to long-term exposure to alternating loads. As the cracks propagate, the connectors eventually fail due to bending, breakage, or other phenomena.

[0004] If the connector fails, not only will it require shutdown to replace the part, causing production interruptions of several hours or even days and resulting in significant economic losses; more seriously, a broken connector may cause the roller shaft to fall off and the equipment to go out of control, posing a great threat to the personal safety of on-site operators.

[0005] In view of this, there is a need in the market for a roller shaft reinforcement connector that can avoid the above problems. Utility Model Content

[0027] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Please see Figures 1-6 A roller shaft reinforcing connector according to an embodiment of the present utility model includes a roller body 1 and a roller shaft body 12 symmetrically arranged at both ends of the roller body 1;

[0029] The surface of the roller body 1 is equipped with a reinforcing connection assembly 2. The reinforcing connection assembly 2 includes reinforcing sleeves 21 symmetrically installed on the surface of the roller body 1, multiple reinforcing ribs 22 installed on the outer side of the reinforcing sleeves 21, and connecting blocks 23, threaded rods 24, connecting grooves 25, and threaded grooves 26 for connection.

[0030] The main body 12 of the cylindrical shaft is inserted into the inside of the reinforcing sleeve 21. The connecting block 23 is installed at one end of the main body 12 of the cylindrical shaft near the roller body 1. Two connecting grooves 25 are symmetrically opened inside the roller body 1, and the connecting block 23 is snapped into the inside of the connecting grooves 25. The threaded rod 24 is installed on one side surface of the connecting block 23. The threaded rod 24 is threaded into the threaded groove 26 opened inside the roller body 1. The reinforcing sleeve 21 is fitted on the surface of the roller body 1, which can directly enhance the basic rigidity of the connection between the roller body 1 and the main body 12 of the cylindrical shaft, and prevent the connection area from being easily bent due to the weak basic structure. Multiple reinforcing ribs 22 are installed on the outer side of the reinforcing sleeve 21, which can further disperse the radial load and torque borne by the connection, reduce stress concentration, and greatly improve the bending resistance.

[0031] Multiple reinforcing ribs 22 are arranged in a circular array around the center point of the reinforcing sleeve 21. The circular array of reinforcing ribs 22 can make the stress points on the outer side of the reinforcing sleeve 21 evenly distributed on the same circumference. When the reinforcing sleeve 21 is subjected to radial force or torque from different directions, each reinforcing rib 22 can share the load synchronously, avoiding the breakage of a single reinforcing rib 22 due to concentrated force.

[0032] The reinforcing sleeve 21 is a stepped cylindrical structure with openings at both ends. The diameter at the connection of the two ends is larger than the diameter at the center, thereby preventing the connection area from being easily bent due to the weak foundation structure.

[0033] A stabilizing component 3 is mounted on the surface of the connecting block 23. The stabilizing component 3 includes a plurality of mounting grooves 31 formed on the surface of the connecting block 23, a rubber strip 32 installed inside the mounting grooves 31, and an inner plate 33 for increasing strength.

[0034] The rubber strip 32 fits tightly against the inner wall of the connecting groove 25, and the two are configured with an interference fit. The connection stability is improved by the cooperation of the connecting block 23 with the threaded rod 24, the connecting groove 25, and the threaded groove 26: the connecting block 23 is snapped into the connecting groove 25 to achieve radial positioning and prevent radial displacement of the main body 12 during operation; the threaded rod 24 is threaded into the threaded groove 26 to form axial fixation and prevent the main body 12 of the main body ...

[0035] The inner plate 33 is embedded inside the connecting block 23, which can enhance the strength of the connecting block 23 itself, prevent the connecting block 23 from breaking due to excessive force, and extend the overall service life of the connector.

[0036] Multiple weight-reducing holes are arranged in a circular array around the center point of the surface of the inner panel 33. The weight-reducing holes can reduce the amount of material used in the inner panel 33, thereby reducing the inertial load during operation, improving transmission efficiency, reducing the consumption of high-strength materials, and further reducing production costs.

[0037] The working principle of this utility model is as follows: Before assembling the connecting parts, each component needs to be pre-processed: First, the connecting areas at both ends of the roller body 1, the outer surface of the roller shaft body 12, and the mating surface of the connecting block 23 are cleaned and polished to remove rust, oil, and burrs from the surface, ensuring the flatness and cleanliness of the assembly surface and avoiding impurities from affecting the connection accuracy; at the same time, check whether there is structural damage to the reinforcing sleeve 21 and reinforcing rib 22 in the reinforcing connecting component 2 and the rubber strip 32 and inner plate 33 in the stabilizing component 3, confirm the thread integrity of the thread rod 24 and the internal thread matching degree of the thread groove 26, and ensure that each component meets the assembly standards;

[0038] The operator first aligns one end of the cylindrical shaft body 12 with the open end of the reinforcing sleeve 21, ensuring that the axis of the cylindrical shaft body 12 is aligned with the axis of the reinforcing sleeve 21. The operator then slowly inserts the cylindrical shaft body 12 into the reinforcing sleeve 21 until the connecting block 23 near the end of the cylindrical shaft body 1 reaches the pre-set connecting groove 25 inside the roller body 1. At this point, the cylindrical shaft body 12 and the inner wall of the reinforcing sleeve 21 form a tightly fitting support structure. Once the connecting block 23 is aligned with the connecting groove 25, the operator pushes the cylindrical shaft body 12 axially, causing the connecting block 23 to fully engage inside the connecting groove 25. The threaded rod 24 on one side of block 23 is precisely aligned with the threaded groove 26 inside the roller body 1. Using a torque wrench or other tools, depending on the actual situation, rotate the drum shaft body 12 to drive the connecting block 23 to rotate synchronously, so that the threaded rod 24 is gradually screwed into the threaded groove 26 until the torque wrench reaches the preset torque value (depending on the specifications of the connecting parts), ensuring that the threaded rod 24 and the threaded groove 26 form a firm threaded connection and preventing loosening during subsequent operation; at the same time, the mating surfaces of the connecting block 23 and the connecting groove 25 are in close contact, forming a radial limit, further improving the connection stability;

[0039] During the process of connecting block 23 being inserted into connecting groove 25, the rubber strip 32 pre-set on the inner sidewall of connecting groove 25 adopts an interference fit structure design and gradually contacts the outer surface of connecting block 23. As connecting block 23 goes deeper, rubber strip 32 is squeezed and undergoes elastic deformation, tightly fitting into the gap between connecting block 23 and connecting groove 25. On the one hand, it fills the gap to prevent shaking, and on the other hand, it weakens the vibration transmission in subsequent operation through the elastic damping effect of rubber.

[0040] Meanwhile, the inner plate 33 embedded inside the connecting block 23 has multiple weight-reducing holes arranged in a circular array around the center point on its surface, and is fixed together with the connecting block 23. The inner plate 33 is made of high-strength alloy material, and its structural strength is much higher than that of the connecting block 23 body material. It can provide internal support for the connecting block 23 through its own rigidity, and prevent the connecting block 23 from deforming when subjected to force. The design of the weight-reducing holes reduces the overall weight of the connecting block 23 while ensuring strength, and reduces the inertial load when the roller shaft is running.

[0041] When the roller shaft starts running, the roller body 1 drives the cylinder shaft body 12 to rotate synchronously. Since the reinforcing sleeve 21 is a stepped cylindrical structure, its larger diameter at both ends can improve the connection strength between the roller body 1 and the cylinder shaft body 12 and avoid excessive local stress. At the same time, multiple reinforcing ribs 22 distributed in a circumferential array around the center point of the reinforcing sleeve 21 are integrally formed with the outer surface of the reinforcing sleeve 21. The reinforcing ribs 22 extend along the axial direction of the reinforcing sleeve 21, which can effectively enhance the radial rigidity of the reinforcing sleeve 21. When the reinforcing sleeve 21 is subjected to radial bending force, the reinforcing ribs 22 can offset part of the force through their own bending resistance, preventing the reinforcing sleeve 21 from deforming and thus avoiding the overall bending of the connection part.

[0042] The inner panel 33 provides internal support for the connecting block 23 through its high strength characteristics; at the same time, the weight-reducing holes on the surface of the inner panel 33 can reduce material stress concentration, prevent the inner panel 33 from cracking due to excessive stress, and further ensure the structural integrity of the connecting block 23.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
