Technical Field
[0001] The utility model relates to mechanical parts, in particular to a combined gear which is easy to process, has high production capacity and low cost. Background Art
[0002] Gears are widely used in many fields. They are a reliable and efficient transmission method, widely used in various mechanical equipment and systems. Gear transmission efficiency is typically above 85%. Gears offer high transmission accuracy, enabling precise speed and position control. Gears generally have a long service life and stable and reliable performance, allowing them to operate under long periods of time and heavy loads without prone to failure. However, gear processing is complex, requiring the use of numerous precision machine tools and high-precision testing equipment. Gear manufacturing also requires a high level of technical expertise. High precision requirements: Gears require high precision. High-power transmissions require thick gears, which are difficult to grind due to their complex geometric dimensions and shapes, as well as the high precision requirements. This results in high gear costs and low production efficiency. Summary of the Invention
[0003] The utility model aims to provide a combined gear which is easy to process, has high production capacity and low cost.

[0005] As a preferred embodiment, the gear plate body and the tooth plate body are correspondingly provided with fixing holes, and the fixing holes of the gear plate body and the tooth plate body are fixed by rivets.
[0006] As a preferred embodiment, the gear piece is fan-shaped, and the tooth piece is correspondingly crescent-shaped.
[0007] As a preferred embodiment, a liner having the same thickness as that of the tooth plate and passing through the main shaft is further provided below the tooth plate.
[0008] As a preferred embodiment, the gear plate and the tooth plate are both formed by stamping of sheet metal.
[0009] As a preferred embodiment, the arc of the gear sector is slightly larger than π / 2.
[0010] The utility model adopts multiple gear plates and tooth plates that are easy to process, and both the gear plates and tooth plates can be processed by sheet metal stamping technology.

[0018] The present invention will be described in further detail below with reference to the embodiments and accompanying drawings.
[0019] In order to reduce the production cost of gears and improve their processing efficiency, the present invention proposes a new combined gear. Figures 1 to 7, including at least one gear plate 1 and at least one tooth plate 4 arranged in sequence at intervals, the gear plate 1 includes a gear plate body 11 mounted on the main shaft 3 and gear teeth 12 arranged on the edge of the gear plate body 11, the tooth plate 4 includes a crescent-shaped tooth plate body 41 and gear teeth 42 arranged on the outer edge of the tooth plate body 41, the gear plate body 11 and the tooth plate body 41 are provided with a fixing structure, after the gear plate body 11 and the tooth plate body 41 are fixed, the gear teeth 12 of the gear plate body 11 and the gear teeth 42 of the tooth plate body 41 overlap.
[0020] This gear is made of a plurality of gear plates 1 and tooth plates 1 that are easy to process, and both the gear plates 1 and tooth plates 1 can be processed by sheet metal stamping technology. The gear teeth positions that are subject to greater force adopt multiple layers of tight stacking to ensure the strength of transmission, while the wheel spokes that are subject to more uniform force adopt a partially hollowed structure. This structural method can ensure precise transmission while greatly saving raw materials. The parts of this structure can be processed by sheet metal stamping technology to effectively reduce processing costs. At the same time, the multi-layer structural combination can use a small number of standardized parts to combine a variety of gears with different strength requirements, which can reduce the variety of warehouse inventory; reduce the processing difficulty of fan-shaped and other special-shaped gears, and the investment in processing equipment is low (the price of a punching machine is much lower than that of a gear hobbing machine, and it can process other hardware products). This product has a low technical threshold for production workers and is easy to realize mold and automated assembly line operations, thus having a greater price advantage than ordinary gears and can effectively improve the company's market competitiveness. Figures 1 to 3 The embodiment in the figure is a structure in which two gear pieces 1 clamp one tooth piece 4, and Figure 6 Another embodiment is a structure in which two tooth pieces 4 clamp a gear piece 1. Figure 7 In another embodiment, three gear plates 1 clamp two tooth plates 4. In other embodiments, different combinations can be used as needed.
[0021] The combined gear of the utility model refers to Figures 1 to 7 Specifically, based on the previous technical solution, the gear plate body 11 and the tooth plate body 41 are correspondingly provided with fixing holes 13 and 43, and the fixing holes 13 and 43 of the gear plate body 11 and the tooth plate body 41 are fixed by rivets 5.
[0022] The combined gear of the utility model refers to Figures 1 to 7 On the basis of the above technical solution, the gear piece 1 is sector-shaped and the tooth piece 4 is crescent-shaped. This makes the processing difficulty of this special-shaped gear the same as that of ordinary products. Of course, in other embodiments, the gear piece can also be disc-shaped and the tooth piece can be annular.
[0023] The combined gear of the utility model refers to Figures 1 to 7On the basis of the previous technical solution, a gasket 2 with the same thickness as the gear plate 4 and passing through the main shaft 3 is further provided under the gear plate 4. The gasket 2 is used to prevent deformation of the contact part between the gear plate 1 and the main shaft 2. In other embodiments, multiple support columns can be used or the protrusion deformation of the main shaft 2 between the two gear plates 1 can be used to produce the same effect.
[0024] The combined gear of the utility model refers to Figures 1 to 7 Specifically, based on the previous technical solution, the gear plate 1 and the tooth plate 4 are both formed by stamping sheet metal.
[0025] The combined gear of the utility model refers to Figures 1 to 7 On the basis of the previous technical solution, the specific embodiment is that the arc of the sector of the gear plate 1 is slightly larger than π / 2, so as to adapt to the reciprocating 90-degree operation of the gate.
[0026] The above is an explanation of the combined gear of the present invention to help understand the present invention. However, the implementation of the present invention is not limited to the above embodiments.
