Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0021] ginseng figure 1 , to introduce a specific embodiment of the gear 10 of the present invention. In this embodiment, the gear 10 includes a body portion 11 and teeth 13 .

[0022] The main body portion 11 includes a shaft hole 12 for matching with an external bearing, and further driving the gear 10 .

[0023] A connecting portion 14 is connected between the teeth 13 and the main body. In this embodiment, the cross-sectional area of ​​the connecting portion 14 is much smaller than the cross-sectional area of ​​the teeth 13 . The advantage of such an arrangement is that the amount of raw materia...

Abstract

The invention discloses a gear, which comprises a body and teeth. The body comprises an axle hole; a connecting part is connected between the teeth and the body; and the teeth are quenched and tempered, so that a quenching and tempering layer is formed on the teeth. The teeth on the gear are quenched and tempered, the Brinell hardness of the teeth is controlled in a range of Brinell hardness (HB) 224-228, and the gear can be used for most of places requiring high-strength gears. Besides, because extra alloy is not added in the gear, the cost of the gear is low.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a gear. Background technique [0002] A gear is a mechanical element with teeth on the rim that can continuously mesh to transmit motion and power. 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 generative gear cutting method and special machine tools and cutting tools using this principle appeared one after another. With the development of production, the stability of gear operation was paid more attention. [0003] Gears are divided into cylindrical gears, bevel gears, non-circular gears, racks, and worm gears according to their shapes; they are divided into spur gears, helical gears, herringbone gears, and curved gears according to the shape of the tooth line; Gears and internal gears; according to the manufacturing method, t...
