Description

Technical Field

[0001] The utility model relates to the technical field of gears, and particularly relates to a high-stability gear. Background Art

[0002] In the fields of mechanical transmission and the entire machinery, gears, as toothed mechanical parts that can mesh with each other, are extremely widely used. As one of the most widely used mechanical transmission methods in modern various equipment, gear transmission has the advantages of accurate transmission ratio, high efficiency, compact structure, reliable operation, long service life, etc.

[0003] For example, Chinese Patent CN202020868498.4 discloses a high-stability gear. The replaceable structure disk facilitates the replacement of the outer edge of the gear after wear, reducing the use cost. The connection structure between the structure disk and the connecting piece is simple, the disassembly is convenient, and the installation is stable.

[0004] However, the installation and disassembly processes are relatively cumbersome, requiring a large amount of time and energy, and the installation stability is not good. It is easy to loosen after long-term use, affecting the normal operation of the gear. Secondly, some gears are prone to problems such as wear and fracture when bearing large torques or high loads, reducing the service life and transmission efficiency of the gears.

[0005] Based on this, the utility model designs a high-stability gear to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a high-stability gear to solve the problems raised in the above background art.

[0007] To solve the above technical problems, the utility model provides the following technical solution: A high-stability gear, including a gear hub, a fixing rod is fixedly connected to the inner wall of the gear hub, a first tooth ring is fixedly connected to the outer wall of the gear hub, second tooth rings are fixedly connected to both the front and rear sides of the first tooth ring, the first tooth ring includes a plurality of tooth blocks one, the tooth blocks one adopt a herringbone structure, and the plurality of tooth blocks one are arranged at equal angles along the circumferences of the axial center of the gear hub, the second tooth ring includes a plurality of tooth blocks two, the tooth blocks two adopt a straight-tooth structure, and the plurality of tooth blocks two are arranged at equal angles along the circumferences of the axial center of the gear hub, an installation ring is embedded in the inner wall at the central position of the fixing rod, and a plurality of short round rods are rotatably connected at equal intervals in the installation ring.

[0008] Preferably, the number of the plurality of tooth blocks one is the same as the number of the plurality of tooth blocks two, and the tooth blocks two in the two second tooth rings correspond to and are fixedly connected to both ends of the tooth blocks one in the first tooth ring.

[0009] Preferably, the width of the first toothed ring is greater than that of the second toothed ring, and the gear hub, the fixing rod, the first toothed ring and the second toothed ring are integrally formed.

[0010] Preferably, a stabilizing sleeve is fixedly connected to the left end of the fixing rod, and the stabilizing sleeve is in a conical structure that is smaller on the left and larger on the right.

[0011] Preferably, the right end of the fixing rod extends out of the right end of the gear hub, and an installation card slot is provided at the edge of the inner cavity on the right side of the fixing rod.

[0012] Preferably, reinforcing ribs are connected to both the left and right sides of the gear hub, and a number of installation holes are equidistantly arranged around the gear hub.

[0013] Preferably, low-friction coatings are applied to the surfaces of the first toothed ring and the second toothed ring.

[0014] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0015] First, by setting the integrally formed gear hub, fixing rod, first toothed ring and second toothed ring, the overall stability of the gear is effectively improved. The herringbone design of the first tooth block not only enhances the meshing ability of the gear but also can alleviate the stress concentration phenomenon caused by uneven force to a certain extent, thereby extending the service life of the gear. The straight-tooth structure of the second tooth block further improves the transmission efficiency and stability of the gear, ensuring that it can still maintain a stable operating state under high torque or high load. By using the short round rods rotatably connected at equal intervals in the installation ring, it can play a certain shock-absorbing role during the operation of the gear, reducing the noise and wear caused by vibration.

[0016] Second, by setting the stabilizing sleeve with a conical structure, the stress is dispersed, the vibration and deviation are reduced, thereby ensuring the smoothness and accuracy of the gear operation. The reinforcing ribs on both sides of the gear hub improve the stability, and a number of installation holes are equidistantly arranged around the gear hub for the user to fix and install according to actual needs. At the same time, the low-friction coatings applied to the surfaces of the first toothed ring and the second toothed ring can reduce the friction loss while ensuring the transmission efficiency, improving the durability of the gear.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1

[0025] Please refer to Figure 1 - Figure 4 To illustrate Embodiment 1, a highly stable gear in the figure includes a gear hub 1. A fixed rod 2 is fixedly connected to the inner wall of the gear hub 1. A first tooth ring 3 is fixedly connected to the outer wall of the gear hub 1. Second tooth rings 4 are fixedly connected to both the front and rear sides of the first tooth ring 3. The first tooth ring 3 includes a plurality of first tooth blocks 301. The first tooth blocks 301 adopt a herringbone structure, and the plurality of first tooth blocks 301 are arranged at equal angles along the circumferential direction of the axis center of the gear hub 1. The second tooth ring 4 includes a plurality of second tooth blocks 401. The second tooth blocks 401 adopt a straight tooth structure, and the plurality of second tooth blocks 401 are arranged at equal angles along the circumferential direction of the axis center of the gear hub 1. An installation ring 5 is embedded in the inner wall at the central position of the fixed rod 2. A plurality of short round rods 6 are rotatably connected at equal intervals in the installation ring 5;

[0026] Please refer to Figure 1 and Figure 2 , the number of the plurality of first tooth blocks 301 in the figure is the same as the number of the plurality of second tooth blocks 401. The second tooth blocks 401 in the two second tooth rings 4 correspond to and are fixedly connected to both ends of the first tooth blocks 301 in the first tooth ring 3;

[0027] Furthermore, the width of the first tooth ring 3 is greater than the width of the second tooth ring 4. The gear hub 1, the fixed rod 2, the first tooth ring 3, and the second tooth ring 4 are integrally formed;

[0028] In this embodiment, the fixed rod 2 is used to connect with the output end of the device to be connected. A number of short round rods 6 rotatably connected in the mounting ring 5 on the inner wall of the fixed rod 2 are used to replace the sliding contact, reducing the frictional loss and resistance. The first tooth ring 3 and the second tooth ring 4 provided on the outer side wall of the gear hub 1 are meshed with other gears or transmission components. The combination of the herringbone tooth block 301 and the straight-tooth structure tooth block 401 not only improves the transmission efficiency of the gear but also enables the gear to have better anti-deformation ability when bearing heavy loads and impacts, ensuring the smoothness and reliability of the transmission.

[0029] In practical applications, when the first tooth ring 3 wider than the second tooth ring 4 contacts the device, it can more effectively disperse the load and reduce the local stress concentration, thereby extending the service life of the gear. At the same time, the integrated design of the first tooth ring 3 and the second tooth ring 4 enhances the integrity and stability of the structure, further improving the load-bearing capacity and anti-fatigue performance of the gear. When the gear meshes with other gears or transmission components, the herringbone structure and the straight-tooth structure on the first tooth ring 3 and the second tooth ring 4 can cooperate with each other to achieve a more stable and efficient transmission.

[0030] Embodiment 2

[0031] Please refer to Figure 1 and Figure 2 To illustrate Embodiment 2, this embodiment further describes Embodiment 1. In the figure, a stabilizing sleeve 7 is fixedly connected to the left end of the fixed rod 2. The stabilizing sleeve 7 is a conical structure with a smaller left end and a larger right end.

[0032] Furthermore, the right end of the fixed rod 2 extends out of the right end of the gear hub 1, and an installation slot 8 is opened at the edge of the right inner cavity of the fixed rod 2.

[0033] In this embodiment, the stabilizing sleeve 7 fixedly connected to the left end of the fixed rod 2 has a conical structure design that can provide better stability. Especially when rotating at high speed or bearing a large lateral force, the conical structure can more effectively disperse the stress, reduce vibration and deviation, thus ensuring the smoothness and accuracy of the gear operation. The installation slot 8 opened at the edge of the right inner cavity of the fixed rod 2 enables the gear to be firmly connected to other devices, improving the convenience of installation and disassembly, and at the same time enhancing the reliability of the connection.

[0034] It should be noted that the material of the stabilizing sleeve 7 can be selected from high-strength and wear-resistant materials to further improve its stability and durability. The specific grooving shape of the installation slot 8 can be adjusted according to the requirements of the connecting piece to enable it to be well adapted to the connection.

[0035] Embodiment 3

[0036] Please refer to Figure 2 and Figure 4Description of Embodiment 3. This embodiment further elaborates on Embodiment 2. In the illustration, reinforcing ribs 9 are connected to both the left and right sides of the gear hub 1, and a number of mounting holes 10 are evenly spaced and circumferentially formed on the gear hub 1.

[0037] Furthermore, low-friction coatings are applied to the surfaces of both the first gear ring 3 and the second gear ring 4.

[0038] In this embodiment, the use of the reinforcing ribs 9 can increase the overall rigidity of the gear and also provide additional support when the gear is subjected to external forces, preventing the gear from deforming or being damaged. At the same time, a number of mounting holes 10 are evenly spaced and circumferentially formed on the gear hub 1. These mounting holes 10 facilitate the fixed connection of the gear to other components, improving the convenience and stability of gear installation. By applying low-friction coatings to the surfaces of the first gear ring 3 and the second gear ring 4, the wear resistance of the gear is improved and the friction coefficient is reduced.

[0039] It should be noted that the low-friction coating can be made of materials such as Teflon or diamond-like carbon. This coating can effectively reduce the wear of the gear during operation, improve the transmission efficiency, and extend the service life of the gear.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
