Description

Technical Field

[0001] The utility model relates to the technical field of wheel structures, and in particular to an asymmetric wheel structure. Background Technique

[0002] The asymmetric wheel structure is an innovative design in the field of vehicle technology, aiming to improve the service performance and life of wheels through an asymmetric design method. The asymmetric wheel structure solves a number of problems such as abnormal vibration through the optimization and improvement of the traditional wheel design, extends the service life of the wheels, and improves the controllability of the vehicle. Its unique design enhances the strength of the wheel structure.

[0003] However, rail gnawing in the overhead crane's trolley is a persistent problem in the operation of the overhead crane, especially for the large wheels of the overhead crane using tapered roller bearings. When designers usually want to change to an automatic alignment wheel set, they need to change the two tapered roller bearings on the inner and outer sides to a single spherical roller bearing and construct a bearing sleeve. Considering the load-bearing capacity, the radial dimension of the spherical roller needs to be increased, which will increase the size of the angular bearing housing, resulting in a change in the center of the wheel and the center of the original reducer. Normally, the reducer motor needs to be moved down a little, but the transformation of the foundation is difficult, with high requirements and a long construction time.

[0004] Therefore, we particularly propose an asymmetric wheel structure. Summary of the Invention

[0036] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1 to 4 , the present invention provides a technical solution:

[0038] An asymmetric wheel structure includes a wheel 1. A rotating shaft 2 is slidably installed at the central position of the wheel 1 from left to right. A self-correcting assembly 4 is provided on the circumferential surface of the rotating shaft 2 on the right side of the wheel 1. The self-correcting assembly 4 includes a deviation-correcting angle box 41 slidably installed on the circumferential surface of the rotating shaft 2. A keyway 43 is provided on the inner circumferential surface of the deviation-correcting angle box 41. A high-strength key 431 is slidably installed inside the keyway 43. A tapered roller bearing 45 is rotatably installed inside the deviation-correcting angle box 41. The tapered roller bearing 45 is rotatably installed on the circumferential surface of the rotating shaft 2.

[0039] A bearing sleeve 44 is slidably installed inside the deviation-correcting angle box 41. The tapered roller bearing 45 is rotatably installed inside the bearing sleeve 44. The number of the tapered roller bearings 45 is two. A washer 451 is installed between the two tapered roller bearings 45. A right rotating ring 47 is rotatably installed on the circumferential surface of the rotating shaft 2 between the wheel 1 and the deviation-correcting angle box 41. A right mounting ring 48 is rotatably installed on the outer circumferential surface of the right rotating ring 47. The left side surface of the right mounting ring 48 is in a fitting state with the central position of the right side surface of the wheel 1.

[0040] On the right side of the deviation correction angle box 41, a right circular ring 49 is fitted and installed. The left side of the right circular ring 49 is in a fitting state with the right side of the bearing sleeve 44. Matching screw holes 411 are provided on the left side to the right side of the right circular ring 49, the bearing sleeve 44, and the right mounting ring 48. A right screw 50 is slidably installed inside the screw hole 411.

[0041] By adopting the above technical solution, including a wheel 1, a circular through-hole is provided on the left side to the right side of the wheel 1, and a pin slot 11 is provided on the inner circumferential surface of the through-hole. Moreover, a rotating shaft 2 is slidably installed in the circumferential through-hole of the wheel 1, and a pin key 23 is fixedly installed on the circumferential surface of the rotating shaft 2. The pin key 23 is slidably installed inside the pin slot 11. Therefore, during subsequent use, the rotating shaft 2 can drive the wheel 1 to rotate synchronously.

[0042] Then, during the operation of the subsequent structure, the wheel 1 will roll along a fixed track, thereby driving the equipment to move. However, during the movement, the wheel 1 will have the situation of rail gnawing. Therefore, a self-correction component 4 is provided on the circumferential surface of the rotating shaft 2 on the right side of the wheel 1.

[0043] Among them, the right rotating ring 47 in the self-correction component 4 is slidably installed on the circumferential surface of the rotating shaft 2 and is in a fitting state with the protruding position on the right side of the wheel 1. Moreover, a right mounting ring 48 is rotatably installed on the outer circumferential surface of the right rotating ring 47.

[0044] Secondly, a deviation correction angle box 41 is slidably installed on the right side of the right mounting ring 48 on the outer circumferential surface of the rotating shaft 2. Among them, a U-shaped key slot 43 is provided on the inner circumferential surface of the deviation correction angle box 41, and a high-strength key 431 is slidably installed inside the key slot 43 for subsequent self-correction of the wheel 1.

[0045] Secondly, a bearing sleeve 44 is slidably installed inside the deviation correction angle box 41. Two tapered roller bearings 45 are rotatably installed inside the bearing sleeve 44, and a washer 451 is installed between the two tapered roller bearings 45 to prevent the two tapered roller bearings 45 from colliding.

[0046] Finally, the right circular ring 49, the bearing sleeve 44, and the right mounting ring 48 are all provided with screw holes 411 from the left side to the right side, and a right screw 50 is slidably installed inside the screw holes 411, so that the structures inside the deviation correction angle box 41 can be closely combined together. Moreover, during use, both the deviation correction angle box 41 and the subsequent left angle bearing box 31 are fixedly installed on the vehicle body to achieve a fixing effect. Moreover, during use, a convex platform is provided on the left side surface of the right mounting ring 48, and the convex platform is in a fitting state with the adjacent tapered roller bearing 45 and the bearing sleeve 44. Moreover, during operation, the rotating shaft 2 drives the wheel 1, the spherical roller bearing 33, and the tapered roller bearing 45 to rotate, and the pusher 42 exerts a force on the bearing sleeve 44, and then adjusts the angle of the wheel 1 with the spherical roller bearing 33 as the rotation center; Therefore, with the cooperation of the above-mentioned multiple structures, the wheel 1 can be self-corrected during driving, so as to avoid the situation of the wheel 1 gnawing on the rail, which ensures the safety of the wheel 1 on the one hand and the safety of the track on the other hand.

[0047] Specifically, as Figures 5 to 6 shown, on the left side of the wheel 1, a left angle bearing box 31 is rotatably installed on the circumferential surface of the rotating shaft 2. A spherical roller bearing 33 is rotatably installed inside the left angle bearing box 31, and the spherical roller bearing 33 is rotatably installed on the circumferential surface of the rotating shaft 2.

[0048] On the left side of the wheel 1, a left rotating ring 34 is slidably installed on the circumferential surface of the rotating shaft 2. A left mounting ring 35 is rotatably installed on the outer circumferential surface of the left rotating ring 34, and the right side surfaces of the left rotating ring 34 and the left mounting ring 35 are in a fitting state with the left side surface of the wheel 1.

[0049] On the left side of the left angle bearing box 31, a left sealing cover 36 is slidably installed on the circumferential surface of the rotating shaft 2. The left sealing cover 36, the left angle bearing box 31, and the left mounting ring 35 are all provided with matching left threaded holes 37 from the left side to the right side, and a left screw 38 is slidably installed inside the left threaded holes 37.

[0050] A pusher 42 is fixedly installed on the circumferential surface of the deviation correction angle box 41 by means of a bracket. External threads 22 are provided on the circumferential surface of the rotating shaft 2, and threaded rings 21 are rotatably installed on the circumferential surface of the rotating shaft 2 at the positions of the external threads 22. The two threaded rings 21 are respectively located inside the corresponding left sealing cover 36 and right circular ring 49. A pin slot 11 is provided on the inner circumferential surface of the wheel 1, and a pin key 23 is fixedly installed on the circumferential surface of the rotating shaft 2, and the pin key 23 is slidably installed inside the pin slot 11.

[0051] By adopting the above technical solution, on the circumferential surface of the rotating shaft 2 on the left side surface of the wheel 1, a left turning ring 34 is slidably installed, and on the outer circumferential surface of the left turning ring 34, a left mounting ring 35 is rotatably installed. Among them, the right side surfaces of the left turning ring 34 and the left mounting ring 35 are in a fitting state with the protruding positions on the left side surface of the wheel 1.

[0052] Then, on the outer circumferential surface of the rotating shaft 2 on the left side of the wheel 1, a left angular bearing housing 31 is slidably installed, and the right side surface of the left angular bearing housing 31 is in a fitting state with the left side surface of the left mounting ring 35.

[0053] After that, a spherical roller bearing 33 is rotatably installed inside the left angular bearing housing 31, and the spherical roller bearing 33 is rotatably installed on the circumferential surface of the rotating shaft 2.

[0054] Secondly, on the circumferential surface of the rotating shaft 2 on the left side of the left angular bearing housing 31, a left sealing cover 36 is slidably installed. A circular through hole is provided at the center position of the left sealing cover 36 for the rotating shaft 2 to pass through. Moreover, left threaded holes 37 are provided on the left side surfaces of the left sealing cover 36, the left angular bearing housing 31, and the left mounting ring 35 to the right side surface. And a left screw rod 38 is slidably installed inside the left threaded hole 37, so that the structures on the left side of the wheel 1 can be closely fitted together to avoid the structure from shaking during subsequent use. Secondly, a protruding boss is provided on the left side surface of the left mounting ring 35 for being in a fitting state with the spherical roller bearing 33 and the left angular bearing housing 31.

[0055] Then, during subsequent use, as the wheel 1 rotates, its left angular bearing housing 31 will also rotate synchronously, so that the two sides of the wheel 1 can rotate concentrically. And under the action of the above structure, the wheel 1 can rotate with the left angular bearing housing 31 on the left side as the axis, and further, during subsequent use of the wheel 1, the wheel 1 can perform self-aligning operation.

[0056] Working principle: First, the rotating shaft 2 is slidably installed inside the wheel 1, so that the rotating shaft 2 can drive the wheel 1 to rotate synchronously during subsequent use.

[0057] Then, when the rotating shaft 2 drives the wheel 1 to rotate, it will also drive the self-correcting component 4 on the circumferential surface of the rotating shaft 2 to rotate synchronously. Then, during subsequent use, the high-strength key 431 in the self-correcting component 4 rotates synchronously, and then the self-correcting component 4 corrects the wheel 1, so that the linear motion of the wheel 1 can be realized.

[0058] In addition, during the rotation of the wheel 1, it will also drive the left angular bearing housing 31 on the left side to move synchronously. At this time, the left angular bearing housing 31 will also drive the internal structure to rotate synchronously.

[0059] Under the action of the above structure, the wheel 1 can thus achieve the correction operation.

[0060] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
