[0022] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with 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 of ordinary skill in the art without any creative labor fall within the protection scope of the utility model.

[0023] The following references are made Figures 1-3 The utility model is explained as follows:

[0024] Embodiment 1: The utility model relates to a kind of axle plate welding reinforcing structure, to solve the problem of existing axle plate welding structure when bearing radial force, welding place is easy to break, poor stability.

[0025] A kind of axle plate welding reinforcing structure, including driving plate 1, bearing seat 2, shaft 3, bearing is installed in bearing seat 2.

[0026] Driving plate 1 is equipped with mounting hole 4, the size and shape of this mounting hole 4 can be connected with bearing seat 2 closely and adapt, provide accurate positioning reference for subsequent welding process, guarantee the assembly accuracy of entire structure.

[0027] Bearing seat 2 is tubular, annular welding ring 5 is equipped on the outer side wall of one end of bearing seat 2, the existence of welding ring 5 increases the welding contact area with driving plate 1, so that the connection is more stable after welding, can more effectively transfer and disperse stress.

[0028] Bearing seat 2 is connected in mounting hole 4, and the outer side wall of bearing seat 2 and welding ring 5 are welded and fixed on the two sides of driving plate 1.This double-sided welding mode, compared with traditional single-sided welding or simple circumferential welding, greatly improves the connection strength.From the mechanical point of view, double-sided welding makes the binding force between driving plate 1 and bearing seat 2 more balanced in each direction, effectively resists the shear stress generated by radial force, reduces the risk of fracture at welding place.

[0029] One end of shaft 3 is adapted to be inserted into bearing seat 2, and shaft 3 is welded and fixed with bearing seat 2.

[0030] Annular limiting ring 6 is provided in bearing seat 2, limiting ring 6 plays a key axial limiting role, accurately controls the depth of shaft 3 inserted into bearing seat 2, and provides additional support point for shaft 3, enhances the stability of shaft 3 under the action of radial force.

[0031] One end of the rotating shaft 3 abuts against and is welded to the limiting ring 6, and one end of the bearing seat 2 is welded to the rotating shaft 3. Through multiple welding connections, a stable force transmission path is constructed to uniformly disperse the radial force to the bearing seat 2 and the entire structural system.

[0032] After the welding of the bearing seat 2 and the driving plate 1 is completed, one end of the rotating shaft 3 is inserted into the bearing seat 2 until it abuts against the limiting ring 6. This precise insertion depth control ensures the correct positioning of the rotating shaft 3 in the bearing seat 2, providing a stable initial state for subsequent welding. Then, the rotating shaft 3, the limiting ring 6, and one end of the bearing seat 2 are sequentially welded and fixed. Through this series of welding operations, a continuous force transmission link is constructed from the rotating shaft 3 to the limiting ring 6, to the bearing seat 2, and finally to the driving plate 1, ensuring that the entire structure cooperates under radial force, avoiding local stress concentration.

[0033] When the bearing and the rotating shaft 3 are subjected to radial force, the load distribution at the connection with the driving plate 1 changes significantly due to the unique structural design of the utility model. Due to the small length of the bearing seat 2, the structure is more compact, and its own structural strength is relatively high. Under the action of radial force, more load will be concentrated on the bearing seat 2 according to the designed path. The bearing seat 2 can effectively bear this part of the concentrated load due to its high strength characteristics, avoiding the direct impact of the load on the welded connection, thereby ensuring the stability and firmness of the welded connection structure. Compared with the traditional shaft plate welding structure, the utility model optimizes the component structure, connection method, and load transmission path, fundamentally improving the reliability of the entire structure under radial force, providing a strong guarantee for the stable operation of mechanical equipment, reducing equipment failure, increasing maintenance costs, and prolonging downtime due to welding fracture.

[0034] The driving plate 1 is located between the welding ring 5 and the limiting ring 6. From the structural layout, the welding ring 5 is on the outer wall of one end of the bearing seat 2 and is an important part of the welding connection between the bearing seat 2 and the driving plate 1, which is connected to the driving plate 1 through a larger annular contact area. The limiting ring 6 is located inside the bearing seat 2 and is used to limit and support the rotating shaft 3 in the axial direction. The driving plate 1 is placed between the two, first forming an orderly nesting relationship in space. This layout makes the overall structure more compact after assembly. Moreover, the load caused by the radial force on the bearing seat 2 and the rotating shaft 3 will act on the area between the welding ring 5 and the limiting ring 6, which has a certain length, enabling it to bear a larger load.

[0035] It also includes a reinforcing plate 7 arranged in parallel and spaced apart from the driving plate 1, a hole on the reinforcing plate 7 for connecting the rotating shaft 3, and a connecting rod 8 between the reinforcing plate 7 and the driving plate 1.

[0036] The reinforcing plate 7 can enhance the radial force bearing capacity. In view of the characteristic that the rotating shaft 3 is long, when the rotating shaft 3 is subjected to the radial force in actual operation, the bending moment and deformation risk generated by the radial force are increased. When the radial force is applied to the rotating shaft 3, the reinforcing plate 7 can share a part of the radial force by virtue of the structural rigidity of the reinforcing plate 7. An additional support plane is equivalent to being added, the stress mode of the rotating shaft 3 originally relying on the bearing seat 2 and the driving plate 1 for support is changed, the radial force is dispersed to a larger bearing area, the load borne by the welding position, especially the welding position of the rotating shaft 3, the bearing seat 2 and the driving plate 1 is effectively reduced, the possibility of welding failure caused by excessive load is greatly reduced, and the stability of the whole structure in long-term operation is ensured.

[0037] In order to ensure that the reinforcing plate 7 and the driving plate 1 can work cooperatively, the two are connected through the connecting rod 8.

[0038] The connecting rod 8 forms a stable frame structure between the reinforcing plate 7 and the driving plate 1, enhances the connecting rigidity between the two, avoids relative displacement or shaking in the process of being subjected to force, and ensures that the force can be smoothly transmitted between the two. Secondly, the circumferentially spaced connecting rods 8 can evenly distribute the interaction force between the reinforcing plate 7 and the driving plate 1 generated by the force, prevent the local connection position from being damaged due to uneven force, and further ensure the reliability of the whole structure.

[0039] The two ends of the connecting rod 8 are respectively provided with threaded holes 9, the reinforcing plate 7 and the driving plate 1 are respectively provided with connecting holes 10 corresponding to the threaded holes 9, and fastening bolts are connected in the threaded holes 9 and the connecting holes 10.

[0040] The side wall of the bearing seat 2 is provided with a welding hole 11 penetrating the inside and outside thereof, and the welding hole 11 is arranged correspondingly to the rotating shaft 3 loaded in the bearing seat 2. The purpose is to further weld and fix the bearing seat 2 and the rotating shaft 3. In the traditional mode of welding only at the end of the bearing seat 2 and the rotating shaft 3, stress concentration is prone to occur at the welding position when a larger radial force is borne, resulting in insufficient connection strength. The newly added circumferentially spaced welding holes 11 provide more welding point positions for welding operation, so that the welding area is increased, and the force can be more evenly distributed on the connecting surface of the bearing seat 2 and the rotating shaft 3. When the radial force acts, multiple welding points bear force together, greatly improving the structural strength of the connection of the two, effectively preventing the welding position of the bearing seat 2 and the rotating shaft 3 from being broken due to the impact of the radial force, and ensuring the integrity and reliability of the whole shaft plate welding structure.

[0041] The newly introduced reinforcing plate 7, connecting rod 8 and welding hole 11 and other components comprehensively improve the shaft plate welding reinforcing structure from the aspects of mechanical enhancement, connection optimization, welding process improvement and the like, so that the structure can better adapt to various complex working conditions, meet higher engineering application requirements, and fully show the innovation and practicality of the utility model.

[0042] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
