Description

Technical Field

[0001] This utility model relates to the field of sector gears, and in particular to a locking mechanism and its sector gear. Background Technology

[0002] Sector gears are mechanical transmission components with simple structure, strong transmission capacity, and long service life. They are widely used in machinery, aviation, aerospace, automotive and other fields.

[0003] A sector gear is mainly composed of several parts, including the gear hub, rim, tooth groove, tooth root, and normal plane. Among them, the rim is an important component of the sector gear. It has an arc-shaped outer contour and is used to mesh with other gears. Therefore, compared with other parts, the rim is more prone to wear, which can lead to errors in accuracy. In this case, the entire sector gear must be replaced, resulting in a waste of resources. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides, for example Figure 1-4 The locking mechanism shown includes a mounting shaft 1, a mounting plate 2, a rim rack 3, a connecting rod 4, and a locking mechanism 5. The mounting plate 2 is fixedly connected to the outer wall of the mounting shaft 1. The rim rack 3 is disposed outside the mounting plate 2 and is arc-shaped. It can be spliced ​​with the fan-shaped section of the mounting plate 2 to form a complete fan-shaped surface. One end of the connecting rod 4 is equidistantly connected to the inner wall of the rim rack 3. The outer wall of the mounting plate 2 is provided with equidistant connecting grooves. The other end of the connecting rod 4 is slidably inserted into the inner cavity of the connecting groove. The locking mechanism 5 is disposed inside the mounting plate 2 and is used for multi-point positioning of the connecting rod 4. The locking mechanism 5 locks the connecting rod 4, so that the rim rack 3 can be installed outside the mounting plate 2 through the connecting rod 4. Therefore, when the rim rack 3 is worn, only the rim rack 3 needs to be removed and replaced, without replacing the entire fan-shaped gear. This not only saves resources and reduces maintenance costs, but also simplifies the replacement process and improves ease of use.

[0031] Specifically, the snap-fit ​​mechanism 5 includes a snap-fit ​​rod 51, a pull rod 52, and a compression spring 53. A through groove is formed between the connecting slots. One end of the snap-fit ​​rod 51 is slidably inserted into the inner cavity of the through groove. A snap-fit ​​hole is formed on the outer wall of the connecting rod 4. The other end of the snap-fit ​​rod 51 is slidably inserted into the inner cavity of the snap-fit ​​hole. A pull groove communicating with the through groove is formed on the outer wall of the mounting plate 2. The pull rod 52 passes through the pull groove and is fixedly connected to the snap-fit ​​rod 51. The compression spring 53 is disposed inside the through groove. An inclined surface is formed at the end of the snap-fit ​​rod 51. The end of the compression spring 53 is connected to the snap-fit ​​rod 51. 51 is fixedly connected, and the compression spring 53 always provides a stable elastic force to the locking rod 51, so that the locking rod 51 can be stably locked with the locking hole, thereby locking the connecting rod 4 inside the mounting plate 2, and thus stably splicing and installing the wheel flange rack 3 with the mounting plate 2. The opening of the bevel of the locking rod 51 makes it convenient to squeeze the locking rod 51 by inserting and pressing during installation. After the connecting rod 4 is inserted into the connecting groove, it pops out again under the elastic force of the compression spring 53 to achieve locking and locking, which is convenient to use.

[0032] Furthermore, the snap-fit ​​mechanism 5 also includes a collar 54, a limiting plate 55, and a bolt 56. The collar 54 is slidably sleeved on the outside of the mounting shaft 1. The limiting plate 55 is symmetrically fixedly connected to the outer wall of the collar 54. The limiting plate 55 is disposed between the tie rods 52 to limit the displacement of the tie rods 52. A countersunk hole is opened at the top of the limiting plate 55, and the bolt 56 is slidably inserted into the inner cavity of the countersunk hole. An installation hole is opened on the outer wall of the mounting plate 2, and the bolt 56 passes through the countersunk hole and is threaded into the inner cavity of the installation hole. The connection is achieved by using bolts 56 to fix the collar 54 to the outer wall of the mounting plate 2. At the same time, the limiting plate 55 on the collar 54 can limit the pull rod 52 to prevent the pull rod 52 from shifting during use of the sector gear, thereby causing the locking rod 51 to disengage from the locking hole and the locking to fail. In addition, when it is necessary to disassemble the rim rack 3, only one bolt 56 needs to be removed to pull the pull rod 52, so that the locking rod 51 disengages from the locking hole, thereby realizing the disassembly of the rim rack 3, which is convenient for use.

[0033] Furthermore, the outer wall of the mounting shaft 1 is provided with sliding grooves at equal intervals. The inner cavity of the sliding groove is slidably connected to a slider 57. The slider 57 is fixedly connected to the collar 54. The slider 57 ensures that the collar 54 can only move vertically along the sliding groove, which facilitates the collar 54 to drive the limiting plate 55 to rise, so that the pull rod 52 is no longer limited, which facilitates the subsequent disassembly of the wheel flange rack 3.

[0034] Furthermore, a sealing plug 6 is slidably inserted into the inner cavity of the countersunk hole. The top of the sealing plug 6 is provided with a pull groove for pulling out the sealing plug 6. The sealing plug 6 plays a protective role for the bolt 56. The sealing plug 6 not only effectively prevents the intrusion of external impurities and moisture, thereby extending the service life of the bolt 56 and reducing the risk of failure caused by corrosion or wear, but also helps to keep the internal environment dry and clean, further ensuring the stability and performance of the bolt 56 and enhancing the safety and durability of the overall system.

[0035] This embodiment provides a sector gear, including the locking mechanism described above.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
