    Technical area
    The invention relates to a drive part for electric vehicle, including a gear.
    Context of the invention
    Now, gears used in transmissions of electric vehicles are of two types, one of steel and another of nylon. Steel gears, which have a high resistance to wear, are noisy. Nylon gears with low resistance are less noisy.
    Description of the invention
    The invention solves the technical problem by providing a gear piece with high wear resistance and resulting in a reduction of operating noise.
    The technical solution of the invention is to provide a gear according to claim 1. The gear comprises a steel substrate in which a mounting hole is arranged, with a first annular groove in an outer peripheral wall of the substrate. with a first annular nylon insert cast in the first annular groove, with multiple first teeth machined on the outer peripheral wall of the substrate, with multiple second teeth machined on the outer peripheral wall of the first annular insert, each complete tooth of the gear being composed of a second tooth disposed between two first corresponding teeth.
    According to one embodiment of multiple first through holes connected to the first annular groove are arranged uniformly in the two side walls of the substrate, with first nylon inserts poured into the first through holes, the first inserts and the first annular insert forming an assembly.
    According to an embodiment of multiple second through holes connected to the mounting hole are arranged uniformly at the bottom of the first annular groove in the substrate, with second inserts in the second through holes, the second inserts and the first insert. ring forming a set.
    According to one embodiment, a second annular groove is arranged at the bottom of the first annular groove in the substrate, the second annular groove comprises a second molded nylon annular insert comprising a narrow opening and a wide bottom, third grooves. which are mutually symmetrical are arranged in two walls of the first annular groove in the substrate, third annular cast nylon inserts are in the third annular grooves, the second annular insert, the third annular inserts and the first annular insert forming a set. .
    A part of a gear with the previous structure of the invention has the advantage over the state of the art. A first annular groove is provided on an outer peripheral wall of the gear substrate of the invention, a first annular nylon insert is cast into the first annular groove, multiple first teeth are machined on an outer circular surface of the substrate, multiple second teeth are machined on an outer circular surface of the first annular insert, one of the multiple first teeth and one of the multiple second corresponding teeth make up a complete tooth. In other words, each complete tooth has two steel ends and a nylon medium. The advantage of steel teeth is the high strength and the advantage of nylon teeth is to be less noisy. Thus, the gear piece of the invention has the advantage of high strength and operates by making a lower noise.
    The first insert serves to prevent rotation of the first nylon annular insert relative to the substrate when the substrate is forced to prevent rotation, and to prevent radial displacement of the first annular insert relative to the substrate.
    The second insert serves to prevent rotation of the first annular insert relative to the substrate when the substrate is forced to prevent rotation.
    The second annular insert and the third annular inserts serve to prevent radial displacement of the first annular nylon insert relative to the substrate when the teeth are forced by a radial component of force.
