Description

Technical Field

[0001] The utility model mainly relates to the technical field of gears, in particular to a special meshing gear set. Background Art

[0002] Gear refers to a mechanical element with teeth on the wheel rim that can continuously mesh to transmit motion and power. Gear meshing transmission is the most widely used mechanical transmission method in various modern equipment. It has relatively accurate transmission, high efficiency, compact structure, reliable operation and long service life.

[0003] At present, when ordinary gears are used for transmission, when two gears are meshed together, generally only a small number of about three or four teeth play a role in meshing transmission, thereby driving the other gear to rotate, and its load-bearing efficiency is limited. If the load is too heavy, it is easy to cause gear damage, causing the teeth to fatigue excessively and break, and it is inconvenient to use. Therefore, it is necessary to propose an improvement measure to solve the above technical problems.

[0004] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content

[0008] To achieve the above-mentioned purpose, the technical solution provided by the utility model is: a special meshing gear set, including a first gear and a second gear, a circular ring I is correspondingly provided in the middle of the gear teeth on the outer edge side wall of the first gear; a circular groove is correspondingly provided in the middle of the gear teeth on the outer edge side wall of the second gear, and both side end faces of the second gear are extended outward to form circular rings II; the circular ring I on the first gear can be matched with the groove on the second gear, and the gear teeth on both sides of the circular ring I on the first gear can mesh with the gear teeth on both sides of the groove on the second gear.

[0009] Furthermore, the thickness of the circular ring I on the first gear matches the thickness of the groove on the second gear.

[0010] Furthermore, the width of the gear teeth on both sides of the circular ring I on the first gear is matched with the width of the gear teeth on both sides of the groove on the second gear.

[0014] 3. Beneficial effects:

[0015] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0016] The utility model has a reasonable design. By correspondingly arranging circular rings and grooves in the middle of the gear teeth on the side walls of the outer edges of the two gears, multiple rows of gear teeth are meshed when the two gears are meshed for transmission. Circular rings are correspondingly arranged in the middle of the first gear and on both sides of the second gear, so that all the gear teeth on the gears can be connected to form an integrated structure to ensure the connection strength.

[0029] Refer to the attached Figure 1-4A special meshing gear set of this embodiment includes a first gear 1 and a second gear 2. A circular ring Ⅰ11 is correspondingly provided in the middle of the gear teeth on the outer edge side wall of the first gear 1. A circular groove 21 is correspondingly provided in the middle of the gear teeth on the outer edge side wall of the second gear 2. The two side end faces of the second gear 2 are all extended outward to form circular rings Ⅱ22. The circular ring Ⅰ11 on the first gear 1 can match the groove 21 on the second gear 2, that is, the circular ring Ⅰ11 on the first gear 1 can be correspondingly inserted into the groove 21 on the second gear 2. The gear teeth on both sides of the circular ring Ⅰ11 on the first gear 1 can mesh with the gear teeth on both sides of the groove 21 on the second gear 2.

[0030] Specifically, the thickness of the circular ring I11 on the first gear 1 matches the thickness of the groove 21 on the second gear 2; the width of the gear teeth on both sides of the circular ring I11 on the first gear 1 matches the width of the gear teeth on both sides of the groove 21 on the second gear 2. The outer diameter of the circular ring I11 on the first gear 1 is consistent with the outer diameter of the gear teeth on the first gear 1; the outer diameter of the circular ring II22 on both sides of the second gear 2 is consistent with the outer diameter of the gear teeth on the second gear 2. Since the two side end faces of the second gear 2 are all extended outward to form circular ring II22, the second gear 2 is thicker than the first gear 1 as a whole.

[0031] The first gear 1 and the second gear 2 can be spur gears or helical gears. The circular ring Ⅰ11 can separate the outer side wall of the first gear 1 to form two rows of gear teeth of equal width; the groove 21 can separate the outer side wall of the second gear 2 to form two rows of gear teeth of equal width. The gears on both sides of the circular ring Ⅰ11 on the first gear 1 are aligned with each other without misalignment. The middle part of the first gear 1 and the second gear 2 can be the same as conventional gears, and corresponding structures such as shaft holes and keyways are provided. In this embodiment, circular rings and grooves are respectively arranged in the middle of the gear teeth on the outer edge side walls of the two gears, so that multiple rows of gear teeth are meshed when the two gears are meshed for transmission, and circular rings are correspondingly arranged in the middle of the first gear 1 and on both sides of the second gear 2, so that all the gear teeth on the gears can be connected to form an integrated structure to ensure their connection strength. When the two gears are meshed for transmission, the circular ring structure on the gears is utilized so that the gears can bear a larger load, effectively avoiding the phenomenon of broken teeth of the gears due to excessive load, greatly improving the load-bearing efficiency of the gears, and being more convenient to use as a whole, with a wider range of applications, and can be well applied to heavy industry, mining, docks, military industry and other industries, with strong practicality and worthy of promotion. Example 2

[0032] On the basis of Embodiment 1, the first gear 1 and the second gear 2 of this embodiment also have another meshing form, namely:

[0033] like Figure 5As shown, the outer edge side walls of the two gears have the same and complete structure. A first circular ring and an annular groove are provided in the middle of the gear teeth on the outer edge side wall of the gear, and the circular ring and the groove separate the outer edge side wall of the gear to form three rows of gear teeth of equal width; a second circular ring is provided on the end face of one side of the gear close to the groove and extends outward. The thickness of the circular ring on one gear matches the thickness of the groove on the other gear; the width of the three rows of gear teeth on the outer edge side walls of the two gears also matches; the outer diameter of the circular ring on the gear is consistent with the outer diameter of the gear teeth on the gear. During installation, the circular ring and the groove on one gear can respectively match the groove and the circular ring on the other gear, and the three rows of gear teeth on the outer edge side walls of the two gears are also meshed together.

[0034] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
