Description

Technical Field

[0001] This utility model relates to the field of straight bevel gear technology, specifically a high-efficiency transmission straight bevel gear. Background Technology

[0002] Spur bevel gears, also known as straight bevel gears, are gears with a conical shape. Their tooth lines are straight lines parallel to the gear axis, hence the name "spur gear." Spur bevel gears offer high transmission efficiency, simple structure, and are easy to manufacture and maintain. However, due to the characteristics of their spur tooth structure, they are prone to generating axial forces during transmission, leading to increased bearing load and requiring high concentricity in mounting position and drive shaft alignment. Therefore, in practical applications, spur bevel gears are typically used in low-speed, heavy-load transmission applications.

[0003] Existing high-efficiency transmission straight bevel gears typically employ a one-piece design. When one part of the gear is damaged, the entire gear needs to be replaced, resulting in high usage and maintenance costs. Furthermore, they have low wear resistance and cannot be installed on connecting shafts of different diameters, thus limiting their application range and flexibility. Therefore, there is an urgent need for a high-efficiency transmission straight bevel gear to solve the above technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency transmission straight bevel gear to solve the problems mentioned in the background art. Existing high-efficiency transmission straight bevel gears usually adopt an integrated design when in use. When a part of the gear is damaged, the entire gear needs to be replaced, which leads to high usage and maintenance costs. Secondly, the wear resistance is not high. In addition, it cannot be installed on connecting shafts of different diameters, resulting in a narrow range of applications and weak flexibility.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency transmission straight bevel gear includes a front gear and a rear gear. The front gear is located directly in front of the rear gear. Both the front gear and the rear gear have connecting holes. A nut is installed in the connecting hole of the front gear. The front gear and the rear gear are connected by a fastening bolt passing through the connecting hole and threaded to the nut. A first rubber ring is provided at the center of the circle formed by the front gear and the rear gear. A second rubber ring is provided inside the first rubber ring. A third rubber ring is provided inside the second rubber ring. Wear-resistant blocks are provided on the outer sides of both the front gear and the rear gear. Several wear-resistant teeth are evenly arranged on the outer side of the wear-resistant metal blocks.

[0007] As a preferred embodiment of this utility model, the inner wall of the connecting hole is provided with an internal thread, and both the wear-resistant block and the wear-resistant gear teeth are made of chromium carbide alloy material.

[0008] As a preferred embodiment of this utility model, the front gear and the rear gear are each provided with six corresponding connecting holes.

[0009] As a preferred embodiment of this utility model, the first rubber ring, the second rubber ring, and the third rubber ring have the same height.

[0010] As a preferred embodiment of this utility model, the thicknesses of the first rubber ring, the second rubber ring, and the third rubber ring decrease sequentially.

[0011] As a preferred embodiment of this utility model, the first rubber ring, the second rubber ring, and the third rubber ring are all hollow cylindrical in shape.

[0012] In a preferred embodiment of this invention, the number of nuts and fastening bolts is set to six.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model adopts a split design with nuts, connecting holes and fastening bolts. When the front gear or rear gear is damaged, only the corresponding damaged front gear or rear gear needs to be replaced, without replacing the whole gear, thereby reducing the cost of use and maintenance.

[0015] 2. By setting a first rubber ring, a second rubber ring, and a third rubber ring, this utility model allows the straight bevel gear to be installed on connecting shafts of different diameters, thus expanding its application range and enhancing its flexibility.

[0016] 3. This utility model improves the wear resistance of the straight bevel gear by setting wear-resistant blocks and wear-resistant gear teeth, both of which are made of chromium carbide alloy material, thereby extending the service life. Attached Figure Description

It is to be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0025] Please see Figure 1-5 A high-efficiency transmission straight bevel gear includes a front gear 2 and a rear gear 1. The front gear 2 is located directly in front of the rear gear 1. Both the front gear 2 and the rear gear 1 have connecting holes 5. A nut 7 is installed in the connecting hole 5 of the front gear 2. The front gear 2 and the rear gear 1 are connected by a fastening bolt 6 passing through the connecting hole 5 and threaded to the nut 7. The gear adopts a split design. When the front gear 2 or the rear gear 1 is damaged, only the corresponding damaged front gear 2 or rear gear 1 needs to be replaced, without replacing the whole gear, thereby reducing the cost of use and maintenance. A first rubber ring 8 is provided at the center of the circle formed by the front gear 2 and the rear gear 1. A second rubber ring 9 is provided inside the first rubber ring 8. A third rubber ring 10 is provided inside the second rubber ring 9. Wear-resistant blocks 3 are provided on the outer sides of both the front gear 2 and the rear gear 1. Several wear-resistant teeth 4 are evenly arranged on the outer side of the wear-resistant metal blocks 3.

[0026] The inner wall of the connecting hole 5 is provided with an internal thread, and both the wear-resistant block 3 and the wear-resistant gear tooth 4 are made of chromium carbide alloy material, which improves the wear resistance of the straight bevel gear and extends its service life.

[0027] The front gear 2 and the rear gear 1 are each provided with six corresponding connecting holes 5 to ensure a tight connection.

[0028] The first rubber ring 8, the second rubber ring 9, and the third rubber ring 10 have the same height.

[0029] The thicknesses of the first rubber ring 8, the second rubber ring 9, and the third rubber ring 10 decrease sequentially.

[0030] The first rubber ring 8, the second rubber ring 9, and the third rubber ring 10 are all hollow cylindrical in shape. By setting the first rubber ring 8, the second rubber ring 9, and the third rubber ring 10, the straight bevel gear can be installed on connecting shafts of different diameters, thus expanding its application range and enhancing its flexibility.

[0031] The number of nuts 7 and fastening bolts 6 is set to six each.

[0032] The working principle and usage process of this utility model are as follows: First, during installation, the front gear 2 and the rear gear 1 are connected by fastening bolts 6 passing through the connecting holes 5 and threaded with nuts 7. The straight bevel gear adopts a split design. When the front gear 2 or the rear gear 1 is damaged, only the corresponding damaged front gear 2 or rear gear 1 needs to be replaced, without the need for overall replacement, thereby reducing the cost of use and maintenance. By setting wear-resistant blocks 3 and wear-resistant teeth 4, and the wear-resistant blocks 3 and wear-resistant teeth 4 are both made of chromium carbide alloy material, the wear resistance of the straight bevel gear is improved, thereby extending its service life.

[0033] By setting a first rubber ring 8, a second rubber ring 9, and a third rubber ring 10, when the diameter of the connecting shaft is large, the second rubber ring 9 and the third rubber ring 10 are removed from the first rubber ring 8, while the first rubber ring 8 remains stationary. Then, the straight bevel gear is installed on the large-diameter connecting shaft. When the diameter of the connecting shaft is medium, the third rubber ring 10 is removed from the second rubber ring 9, while the first rubber ring 8 and the second rubber ring 9 remain stationary. Then, the straight bevel gear is installed on the medium-diameter connecting shaft. When the diameter of the connecting shaft is small, the first rubber ring 8, the second rubber ring 9, and the third rubber ring 10 remain stationary, and the straight bevel gear is installed on the small-diameter connecting shaft. This allows the straight bevel gear to be installed on connecting shafts of different diameters, expanding its application range and enhancing its flexibility.
