Detailed Description

The technical solution in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

It is to be understood that the described embodiments are merely some embodiments and not all embodiments of the present application, and that the following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application and its applications.

In the present invention, the terms "first", "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance; the term "plurality" means two or more unless expressly limited otherwise. The terms "mounted," "connected," "fixed," and the like are to be construed broadly and include, for example, fixed connections, detachable connections, or all manner of connections; "coupled" may be direct or indirect through an intermediary. The terms "upper", "lower", and the like indicate orientations or positional relationships based on the manner or positional relationships shown in the drawings, and are merely for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referred devices or units must have a specific orientation, be constructed and operated in a specific orientation. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

As shown in fig. 1, a schematic structural diagram of a conventional gear is shown, in the structure of the conventional gear, the gears are completely integrally formed, and two gears are prone to be worn excessively in a meshing area, so that gear teeth in the meshing area are broken or damaged, and especially when a conventional gear mechanism is overloaded, the wear of the meshing area of the gears is further increased. Therefore, gears need to be replaced frequently, small-batch gears are easy to replace, but once large-batch gears are worn and need to be replaced, the working efficiency is undoubtedly reduced, the consumed time is long, and the smooth operation of production work is seriously influenced.

In order to solve the above problems, the present invention provides a novel gear, as shown in fig. 2-3, the novel gear comprises a large half wheel 1 and a small half wheel 2, the large half wheel 1 and the small half wheel 2 are mutually adapted and mutually embedded to form a complete gear.

More specifically, in the region where the large half wheel 1 and the small half wheel 2 are mutually embedded, at least two mounting grooves 14 are arranged on the large half wheel 1, at least two mounting protrusions 21 are arranged on the small half wheel 2, and at least two mounting grooves 14 and at least two mounting protrusions 21 are mutually matched and can be embedded together. The large half wheel 1 and the small half wheel 2 are mutually embedded together through at least two mounting grooves 14 and at least two mounting protrusions 21 to form a complete gear. Preferably, the large half wheel 1 and the small half wheel 2 are in transition fit.

Further, the novel gear is provided with grooves 12, the grooves 12 are uniformly distributed on the outer surface of the novel gear, the number of the grooves 12 is multiple, and preferably, the number of the grooves is 4.

Further, reinforcing ribs 11 are further arranged on the novel gear, the reinforcing ribs 11 are arranged between the two grooves 12, the number of the reinforcing ribs 11 is equal to that of the grooves 12, and preferably, the number of the reinforcing ribs 11 is 4.

Furthermore, the novel gear also has a shaft hole 5, and the shaft hole 5 is arranged at the center position of the novel gear and penetrates through the novel gear.

Further, the mounting groove 14 on the large half wheel 1 is an i-shaped groove.

Further, the mounting protrusion 21 on the small half wheel 2 is an i-shaped protrusion.

It is worth mentioning that the width of the two sides of the small half wheel 2 is equal to the diameter of the shaft hole 13 of the large half wheel 1.

When the semi-wheel is used, the small semi-wheel 2 is only needed to be embedded into the large semi-wheel 1, so that the small semi-wheel and the large semi-wheel are in transition fit. And the middle tooth area of the small half wheel 2 is most easily abraded when the gear works, so that the small half wheel 2 is removed from the large half wheel 1 after the gear is damaged, and the small half wheel is repaired or replaced, so that the whole process is convenient and quick, and the cost is saved.
