Embodiment 1

[0012] See Figure 1-3 , The shredder gear 1 of this embodiment adopts a metal ring 2 for injection molding at one time.

[0013] The shaft hole 3 of the gear 1 is distributed coaxially with the eyelet 2 to ensure the reliability and service life of the gear. The diameter of the metal ring 2 is slightly larger than the shaft hole of the gear 1, so as to ensure that the gear 1 is closely matched with the rotating shaft and prevent the gear from cracking.

[0014] In other embodiments, the gear 1 can be injection-molded with a plurality of concentrically distributed metal rings 2 to further improve its mechanical strength and be applied in a harsh environment.

Abstract

The invention relates to a gear which is simple in structure and high in reliability and used for a paper shredder. The gear is characterized by being formed by performing injection molding on one metal ring or a plurality of metal rings which are concentrically distributed at one time. An axle hole of the gear is coaxial with the metal ring, so that the reliability and the service life of the gear are guaranteed. The gear for the paper shredder is formed by performing injection molding on the metal ring at one time, so that the mechanical intensity of the gear is improved, and the problem that the gear for the paper shredder is cracked in a using process can be solved. Therefore, the gear has the characteristics of simple structure, high reliability and long service life.

Description

technical field [0001] The invention relates to the technical field of gears, in particular to a gear for a paper shredder. Background technique [0002] The gears of existing paper shredders often adopt plastic injection molding. Its shortcoming is: in the course of long-term use, this gear often takes place cracking, causes paper shredder not to work normally. How to provide a shredder gear with good reliability and long service life is a technical problem in this field. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a shredder gear with simple structure, high reliability and long service life. [0004] In order to solve the above technical problems, the present invention provides a gear for a paper shredder, which is characterized in that: the gear adopts one metal ring or a plurality of concentrically distributed metal rings for one-time injection molding. [0005] Specifically, the shaft hole of the gear...
