Description

Technical Field

[0001] This utility model relates to the field of gear forging technology, specifically a high-strength lightweight gear forging. Background Technology

[0002] In the field of mechanical transmission, gears are core components, and their performance has a decisive impact on the operating efficiency and reliability of equipment. With the increasing demand for lightweight and efficient equipment in modern industry, high-strength lightweight gear forgings have become a research hotspot.

[0003] Currently, traditional gear forgings have certain structural design flaws. Most gears adopt an integral structure, requiring complete disassembly for parts replacement, which is cumbersome and time-consuming, severely impacting equipment maintenance efficiency. Although some gears have detachable structures, the connection strength is insufficient, making them prone to loosening or even falling off under high loads, posing significant safety hazards. In addition, traditional gears have poor heat dissipation performance, easily leading to excessively high gear temperatures during prolonged operation, accelerating material aging and reducing gear lifespan. Furthermore, in terms of lightweighting, existing technologies struggle to effectively reduce gear weight while maintaining high strength, failing to meet the application requirements of aerospace, new energy vehicles, and other fields sensitive to component weight.

[0004] Publication number: CN222760123U. This utility model enables the mounting shaft section to extend and retract under the guidance and limiting of the guide seat and guide groove by rotating the threaded sleeve. Moving the mounting shaft section out increases the length of the gear shaft body, while moving the mounting shaft section in decreases the length of the gear shaft body. The length of the gear shaft body can be flexibly adjusted according to the gear installation requirements, making it suitable for various usage needs and effectively improving the flexibility of the gear shaft body.

[0005] To address the aforementioned issues, traditional gear forgings suffer from defects, and replacing defective parts as a single unit is cumbersome, time-consuming, and does not reduce weight. Therefore, we propose a high-strength, lightweight gear forging. Utility Model Content

[0028] Furthermore, the external support 3 is fixedly connected to the top of the gear 12, and the external shape of the support 3 is cylindrical.

[0029] Structural Description: Outer Ring Column 1: This is the external main structure of the gear forging. It is cylindrical in shape and has multiple elongated tooth blocks 2 fixedly connected to the bottom of its outer surface for meshing with other gears or transmission components to transmit power. It has holes inside for installing components such as the fixing column 7, and a threaded groove 13 is provided at the top of the inside for connecting with other components.

[0030] Long toothed blocks 2: Fixedly connected to the outer bottom end of the outer ring column 1, multiple long toothed blocks 2 are evenly distributed, serving as gear teeth, and meshing with the teeth of other gears during transmission to transmit power from one component to another.

[0031] Support 3: Located inside the gear forging, it is cylindrical on the outside and is fixedly connected to the top of the gear 12. It serves to support and fix the gear 12 and ensure the stability of the gear 12 during operation.

[0032] Hollow ring 4: It is fixedly connected to the bottom of the inner ring column 1. A slide 5 is provided on one side of the inner ring. The hollow ring 4 mainly serves to limit and support the fixed column 7. It cooperates with the protrusion 6 on the fixed column 7 to allow the fixed column 7 to rotate within a certain range, while limiting its axial and radial displacement.

[0033] Slide 5: Located inside the hollow ring 4, it is the sliding track of the protrusion 6. The protrusion 6 slides in the slide 5, so that the fixed column 7 and the outer ring column 1 form a rotatable connection, while ensuring the stability and accuracy of the fixed column 7 during rotation.

[0034] Protrusion 6: Fixedly connected to one end of the fixed column 7, in multiple quantities. The outside of the protrusion 6 is slidably connected to the inside of the slide 5. Through cooperation with the slide 5, the fixed column 7 is rotatably connected inside the outer ring column 1. In addition, during the operation of the gear, it shares part of the force and enhances the reliability of the structure.

[0035] Fixed post 7: Installed in the hole inside the outer ring post 1, with a protrusion 6 fixedly connected to one end on the outside and a toothed ring fixedly connected inside, and meshing with the gear 12. The fixed post 7 is mainly used to fix and support the gear 12 and transmit the rotation of the outer ring post 1 to the gear 12, while also bearing a certain torque and pressure itself.

[0036] Rubber sleeve 8: It is fixedly connected to the outer top of the outer ring column 1, and a flange 10 is provided inside it. The rubber sleeve 8 has a certain elasticity, which can play a role in buffering and shock absorption, reducing the vibration and noise generated during gear operation, and also preventing external impurities from entering the gear.

[0037] Nut 9: Threaded connection to the outer side of flange 10, with a bolt at the bottom. Nut 9 and bolt work together to tightly connect flange 10 to outer ring post 1, providing reliable fastening force and ensuring the connection stability between gear components.

[0038] Flange 10: Located inside the rubber sleeve 8, it is a set of connecting parts. It is connected to the outer ring post 1 by nuts 9 and bolts. At the same time, a support post 3 is fixedly connected in the center of the interior, which plays the role of connecting and fixing other parts to ensure the coordinated work between the various parts of the gear.

[0039] Square toothed block 11: The specific function and connection relationship of this component are not mentioned in the text. This may be due to missing information in the document or the component being used in other specific scenarios. If it exists and participates in gear operation, it may be used to mesh with other components with special structures to achieve specific transmission functions.

[0040] Gear 12: Located inside the fixed column 7, it meshes with the fixed column 7. Multiple tooth blocks are provided on the outside, and a heat dissipation hole is opened in the center. Gear 12 is a key component for realizing power transmission and speed change. By meshing with the fixed column 7, it further transmits power or changes parameters such as speed and torque. The heat dissipation hole is used to dissipate heat during the operation of the gear and ensure that the gear is within the normal operating temperature range.

[0041] Threaded groove 13: Multiple grooves are formed on the outer top of the outer ring column 1. The outer shape is an oblique triangular prism. The threaded groove 13 is matched with the flange 10. The outer ring column 1 and the flange 10 are firmly connected by the nut 9 and bolts, which enhances the integrity and stability of the gear structure.

[0042] Instructions for use

[0043] When power is input, the outer ring column 1 begins to rotate. Since the fixed column 7 is slidably connected to the slide rail 5 on the hollow ring 4 via the protrusion 6, and the fixed column 7 meshes with the gear 12, the rotation of the outer ring column 1 will drive the fixed column 7 and the connected gear 12 to rotate together, thus realizing the transmission of power. The threaded groove 13 at the top of the inner end of the outer ring column 1 is connected to the flange 10 inside the rubber sleeve 8 by a nut 9 and bolts. This threaded connection provides reliable fastening force, ensuring that during gear operation, the outer ring column 1, the flange 10, and other components connected to the flange 10 remain firmly connected and will not... When relative displacement occurs, the fixed column 7 cooperates with the slide 5 of the hollow ring 4 through the protrusion 6, which can not only ensure that the fixed column 7 can rotate within a certain range, but also limit the fixed column 7 in the axial and radial directions, so as to stabilize the entire gear structure. When the gear 12 rotates, the heat dissipation hole in the center of the outside of the gear 12 forms natural convection by utilizing the air flow. As the gear 12 rotates at high speed, air is continuously drawn into the heat dissipation hole and then flows out from other parts of the gear 12, thereby carrying away the heat generated during the operation of the gear 12, playing a role in heat dissipation and cooling, and maintaining the gear 12 within the normal operating temperature range.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
