The fracture-resistant gear includes a gear disk and gear teeth arranged around the outer wall of the gear disk. The gear disk is arranged in a ring structure, and a tooth core is provided at the center of the inner side of the gear disk. A spline is formed in the middle of the surface of the tooth core. A first reinforcing rib with an inclination angle is fixedly connected between the inner wall of the gear disk and the outer wall of the tooth core. Multiple first reinforcing ribs are arranged in the radial position of the gear disk. The gear disk can transmit the reverse force along the inclination direction of the first and second reinforcing ribs to the tooth core.

Description

Technical Field

[0001] This utility model relates to the field of transmission components technology, and more specifically, to anti-fracture gears. Background Technology

[0002] A gear is a mechanical component that transmits motion and power through continuous meshing of gears on its rim. It is a toothed mechanical part that can mesh with each other; the diameter of a large gear is twice that of a small gear. Gears have been used in transmission for a long time. In the late 19th century, with the emergence of the principle of generating gear cutting and specialized machine tools and cutting tools using this principle, the smoothness of gear operation became increasingly important as production developed.

[0003] Future gears are developing towards heavy loads, high speeds, high precision, and high efficiency, striving for smaller size, lighter weight, longer lifespan, and economic reliability. However, existing gears are prone to damage from impacts due to prolonged use, have lower strength, are heavier, and are less stable during transmission. A current patent for a high-strength axle gear (patent number CN213744797U) includes a gear disk and gear teeth. The gear disk is a centrally hollowed-out ring, with multiple gear teeth fixedly mounted on its outer side. A gear core is located in the center of the gear disk, with its two ends protruding above and below the gear disk. A spline is provided in the middle position; multiple reinforcing ribs are provided between the gear core and the gear disk. The reinforcing ribs have a certain angle and the bottom of the reinforcing ribs is fixedly installed on the outer surface of the gear core, while the top of the reinforcing ribs is fixedly installed on the inner surface of the gear disk. The surfaces of the gear disk, gear core, and reinforcing ribs are all provided with a corrosion-resistant layer. The reinforcing ribs act as jacks, capable of supporting huge reaction forces without breaking. They can also effectively absorb impact forces to prevent gear breakage and damage during transmission. Furthermore, the gears are lighter, use less material, and are more stable during transmission, making them suitable for more applications.

[0004] However, the reinforcing ribs in patent authorization number CN213744797U are set at an angle in the same direction. As a result, the gear can only provide support in one direction during operation. Since the existing gears need to work in both forward and reverse directions, the reinforcing ribs cannot provide good support when the gear rotates in the opposite direction, which can easily lead to the gear breaking during transmission. Therefore, we proposed an anti-breakage gear to solve the above-mentioned problems. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a fracture-resistant gear. It can transmit the reverse force to the gear core along the inclined direction of the first and second reinforcing ribs through the gear disk. The reverse force is in the opposite direction of the inclined direction of the first and second reinforcing ribs. Therefore, the force acts on the first and second reinforcing ribs, so the first and second reinforcing ribs have the function of a jack, enabling the gear to support the huge reaction force without breaking, whether it rotates forward or backward.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] The anti-fracture gear includes a gear disk and gear teeth arranged around the outer wall of the gear disk. The gear disk is arranged in a ring structure. A tooth core is provided at the center of the inner side of the gear disk. A spline is formed in the middle of the surface of the tooth core.

[0010] A first reinforcing rib with an inclination angle is fixedly connected between the inner wall of the gear disk and the outer wall of the gear core, and multiple first reinforcing ribs are arranged in the radial position of the gear disk.

[0011] A second reinforcing rib with an inclination angle is fixedly connected between two adjacent first reinforcing ribs, and multiple second reinforcing ribs are arranged in the radial position of the gear disk;

[0012] The inclination angles between the first reinforcing rib and the second reinforcing rib are set in opposite directions.

[0013] The inner ring edge of the gear disk is integrally formed with a first reinforcing ring symmetrically.

[0014] The outer edge of the tooth core is integrally formed with a second reinforcing ring.

[0015] Furthermore, five first reinforcing ribs are specifically provided, and the angle between two adjacent first reinforcing ribs and the axial line of the tooth core is 72°.

[0016] Furthermore, five second reinforcing ribs are specifically provided, and the angle between two adjacent second reinforcing ribs and the axial line of the tooth core is 72°.

[0017] Furthermore, the edges of both the first reinforcing ring and the second reinforcing ring are rounded.

[0018] Furthermore, the gear teeth and the spline are coated with a wear-resistant coating.

[0019] Furthermore, the gear disk, gear core, first reinforcing rib, second reinforcing rib, first reinforcing ring, and second reinforcing ring are all coated with a corrosion-resistant coating.

[0020] 3. Beneficial Effects

[0021] Compared with existing technologies, the advantages of this utility model are:

[0022] (1) In this scheme, the tilt angle of the first reinforcing rib and the second reinforcing rib can make the gear as a whole receive the reverse force from the gear that meshes with it, and the gear disk transmits the reverse force to the tooth core along the tilt direction of the first reinforcing rib and the second reinforcing rib. The reverse force is in the opposite direction along the tilt direction of the first reinforcing rib and the second reinforcing rib. Therefore, the force acts on the first reinforcing rib and the second reinforcing rib. Thus, the first reinforcing rib and the second reinforcing rib have the function of a jack, so that the gear can support the huge reaction force without breaking, whether it rotates forward or backward.

[0023] (2) In this scheme, the first reinforcing ring and the second reinforcing ring can provide better resistance to radial bending force for the gear as a whole, thereby improving the load of radial force resistance of the gear as a whole, further improving the structural strength of the gear, and preventing gear breakage.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] Example:

[0032] Please see Figure 1-4 The anti-fracture gear includes a gear disk 1 and gear teeth 2 arranged around the outer wall of the gear disk 1. The gear disk 1 is arranged in a ring structure. A tooth core 3 is provided in the inner center of the gear disk 1. A spline 4 is provided in the middle of the surface of the tooth core 3.

[0033] A first reinforcing rib 5 with an inclination angle is fixedly connected between the inner wall of the gear disk 1 and the outer wall of the gear core 3, and multiple first reinforcing ribs 5 are provided in the radial position of the gear disk 1.

[0034] A second reinforcing rib with an inclination angle is fixedly connected between two adjacent first reinforcing ribs 5, and multiple second reinforcing ribs 6 are provided in the radial position of the gear disk 1;

[0035] The inner edge of the gear disk 1 has a first reinforcing ring 7 integrally formed symmetrically;

[0036] The outer edge of the tooth core 3 is symmetrically and integrally formed with a second reinforcing ring 8;

[0037] It should be noted that when using this anti-fracture gear, the transmission shaft is first fixedly installed in the spline 4 located in the middle of the gear core 3. Then, the gear meshes with other transmission gears. The inclined angle of the first reinforcing rib 5 and the second reinforcing rib 6 allows the gear as a whole to be subjected to the reverse force from the gears meshing with it. The gear disk 1 transmits the reverse force to the gear core 3 along the inclined direction of the first reinforcing rib 5 and the second reinforcing rib 6. The reverse force is in the opposite direction of the inclined direction of the first reinforcing rib 5 and the second reinforcing rib 6. Therefore, the force acts on the first reinforcing rib 5 and the second reinforcing rib 6. Thus, the first reinforcing rib 5 and the second reinforcing rib 6 have the function of a jack, so that the gear can support the huge reaction force without breaking, whether it rotates forward or backward. It can absorb the impact force to prevent damage to the gear teeth 2 during transmission. Moreover, it is lighter, uses less material, and is more stable during transmission, making it suitable for more occasions.

[0038] Furthermore, the first reinforcing ring 7 and the second reinforcing ring 8 can provide better resistance to radial bending force for the gear as a whole, thereby improving the overall resistance to radial force load of the gear and further improving the structural strength of the gear, preventing gear breakage.

[0039] like Figure 1 , Figure 4 As shown, the inclination angles between the first reinforcing rib 5 and the second reinforcing rib 6 are opposite to each other. There are five first reinforcing ribs 5, and the angle between two adjacent first reinforcing ribs 5 and the axial line of the tooth core 3 is 72°. There are five second reinforcing ribs 6, and the angle between two adjacent second reinforcing ribs 6 and the axial line of the tooth core 3 is 72°.

[0040] It should be noted that the tilt angle of the first reinforcing rib 5 and the second reinforcing rib 6 allows the gear as a whole to be subjected to the reverse force from the gear it meshes with. The gear disk 1 transmits the reverse force to the gear core 3 along the tilt direction of the first reinforcing rib 5 and the second reinforcing rib 6. The reverse force is in the opposite direction of the tilt direction of the first reinforcing rib 5 and the second reinforcing rib 6. Therefore, the force acts on the first reinforcing rib 5 and the second reinforcing rib 6. Thus, the first reinforcing rib 5 and the second reinforcing rib 6 have the function of a jack, enabling the gear to support the huge reaction force without breaking, whether it rotates forward or backward.

[0041] like Figure 1 , Figure 2 As shown, the edges of both the first reinforcing ring 7 and the second reinforcing ring 8 are rounded.

[0042] It should be noted that stress should be avoided to prevent cracking at the edges of the first reinforcing ring 7 and the second reinforcing ring 8.

[0043] The gear teeth 2 and spline 4 are coated with a wear-resistant coating, which is a tungsten carbide wear-resistant coating.

[0044] The gear disk 1, gear core 3, first reinforcing rib 5, second reinforcing rib 6, first reinforcing ring 7 and second reinforcing ring 8 are all coated with a corrosion-resistant coating, which is a graphene coating.

[0045] In use: First, the drive shaft is fixedly installed in the spline 4 located in the middle of the gear core 3. Then, the gear meshes with other transmission gears. The inclined angle of the first reinforcing rib 5 and the second reinforcing rib 6 allows the gear as a whole to be subjected to the reverse force from the gears meshing with it. The gear disk 1 transmits the reverse force to the gear core 3 along the inclined direction of the first reinforcing rib 5 and the second reinforcing rib 6. The reverse force is in the opposite direction of the inclined direction of the first reinforcing rib 5 and the second reinforcing rib 6. Therefore, the force acts on the first reinforcing rib 5 and the second reinforcing rib 6. Thus, the first reinforcing rib 5 and the second reinforcing rib 6 have the function of a jack, so that the gear can support the huge reaction force without breaking, whether it rotates forward or backward. It can absorb the impact force to prevent damage to the gear teeth 2 during transmission. Moreover, it is lighter, uses less material, and is more stable during transmission, making it suitable for more occasions.

[0046] Furthermore, the first reinforcing ring 7 and the second reinforcing ring 8 can provide better resistance to radial bending force for the gear as a whole, thereby improving the overall resistance to radial force load of the gear and further improving the structural strength of the gear, preventing gear breakage.

[0047] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
