Embodiment 1

[0014] Such as figure 1 and figure 2 As shown, the gear of the present invention includes a base body 1 made of iron and steel. The base body 1 is provided with a mounting hole 2. The outer peripheral wall of the base body 1 is provided with a circle of first annular grooves 3, and the first annular groove 3 is poured with nylon material. The first annular insert 4 has a plurality of first teeth 14 processed on the outer circumference of the base body 1, and a plurality of second teeth 5 are simultaneously processed on the outer circumference of the first annular insert 4. The tooth 14 and the plurality of second teeth 5 correspond one by one to form a complete tooth.

Embodiment 2

[0016] Such as image 3 and Figure 4 As shown, the gear of the present invention includes a base body 1 made of iron and steel. The base body 1 is provided with a mounting hole 2. The outer peripheral wall of the base body 1 is provided with a circle of first annular grooves 3, and the first annular groove 3 is poured with nylon material. The first annular insert 4, six first through holes 6 communicating with the first annular groove 3 are evenly distributed on the two side walls of the base body 1, and the first through holes 6 are poured with a first insert 7 made of nylon material , the first insert 7 and the first annular insert 4 are an integral structure, a plurality of first teeth 14 are processed on the outer circumference of the base body 1, and multiple teeth 14 are processed on the outer circumference of the first annular insert 4 simultaneously. A second tooth 5, a plurality of first teeth 14 and a plurality of second teeth 5 form a complete tooth in one-to-one ...

Abstract

The invention relates to a low-noise gear. It is characterized in that: the outer peripheral wall of the base body is provided with a circle of first annular groove, and the first annular insert made of nylon material is poured into the first annular groove, and the outer circular surface of the base body is processed with multiple a plurality of first teeth, and a plurality of second teeth are simultaneously processed on the outer surface of the first annular insert, and the plurality of first teeth and the plurality of second teeth form a complete set of teeth in one-to-one correspondence. The two ends of each complete tooth of the present invention are made of steel, and the middle is made of nylon. The teeth of steel have the advantage of high strength, and the teeth of nylon have the advantage of low noise. Therefore, the gear of the present invention simultaneously It has the advantages of high strength and low noise during operation.

Description

technical field [0001] The invention relates to a low-noise gear. Background technique [0002] At present, there are mainly two types of gears used in the deceleration mechanism of electric vehicles, one is steel gears, and the other is nylon gears. Steel gears have higher strength but have the disadvantage of loud noise during operation. , The gear made of nylon has the disadvantage of low noise but low strength during work. Contents of the invention [0003] In view of the problems existing in the prior art, the purpose of the present invention is to provide a technical solution for low-noise gears. [0004] The low-noise gear described above comprises a base made of iron and steel, and the base is provided with mounting holes, and is characterized in that: a circle of first annular grooves is provided on the outer peripheral wall of the base, and the first annular grooves A first annular insert made of nylon material is poured into the groove, a plurality of first te...
