Embodiment Construction

[0012] Specific embodiments of the present invention will be further described in detail below. It should be understood that the description of the embodiments of the present invention here is not intended to limit the protection scope of the present invention.

[0013] Such as Figure 1 to Figure 2 As shown, it is a structural schematic diagram of a light-weight and high-wear-resistant double-arc gear provided by the present invention. The lightweight and high wear-resistant double-arc gear includes a gear body 10 and a plurality of gear teeth 20 arranged on the gear body, and the lightweight and high-wear-resistant double-arc gear also includes other functional modules , such as snap slots, snap blocks, etc., which should be known to those skilled in the art, and will not be described in detail here.

[0014] The gear body 10 is made of hard nylon material, such as nylon 66. It is used to carry the gear teeth 20 and is connected with an external driving device.

Abstract

The invention discloses a lightweight high-wear-resistance double-arc gear. The lightweight high-wear-resistance double-arc gear comprises a gear body and gear teeth, each gear tooth of the gear body comprises a tooth top face, two tooth root faces connected with the gear body and two tooth end faces, two ends of each tooth end face are connected with the tooth top face and the corresponding tooth root face correspondingly, each tooth top face is designed to be in an arc shape, each tooth root face is designed to be semicircular, two tooth root faces are matched to form a concave tooth profile, and the arc radius of each tooth top surface is the same as that of each concave tooth profile. The gear teeth are designed into helical teeth, so that the meshing performance is further improved. Hard nylon has a self-lubricating characteristic, so that the wear time can be greatly prolonged by virtue of the self-lubricating characteristic of the hard nylon even under the condition of insufficient lubrication. The gear is simple in structure and easy to manufacture, the situation that an existing metal gear is extremely easy to damage when lubrication is insufficient is greatly improved, the self weight of the gear is far lower than that of a metal gear of the same specification, the load of an external driving device is greatly reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of gears, in particular to a light-weight and high-wear-resistant double-arc gear. Background technique [0002] Gears are wheel-shaped mechanical parts that transmit torque by the meshing of teeth. Through transmission with other toothed mechanical parts (such as another gear, rack, worm), the gear can realize functions such as changing the speed and torque, changing the direction of motion, and changing the form of pain. Gears are toothed mechanical parts that can mesh with each other, and the application of gears in transmission has appeared very early. At the end of the 19th century, the principle of the generative gear cutting method and the use of special machine tools and cutting tools that were far away from gear cutting appeared one after another. With the development of production, the stability of gear operation was paid more attention. One of the important reasons that affect the life and stabi...
