Background technology：
At present, the gear in electric motor car reducing gear mainly has two kinds, and a kind of is the gear of iron and steel material quality, another kind of
It is the gear of nylon material, the strength of gear teeth of iron and steel material quality is higher but operationally has the shortcomings that noise is big, nylon material
Gear operationally has the shortcomings that noise is low but has intensity little.
The content of the invention：
The technical problem to be solved in the present invention be to provide it is a kind of not only have intensity higher and operationally have make an uproar
The transmission gear for electric motor bicycle of the less advantage of sound.
The technical solution of the present invention is to provide a kind of transmission gear for electric motor bicycle with following structure：Including steel
The matrix of iron material matter, matrix is provided with installing hole, wherein, the intersection of the periphery wall of matrix and a side wall is provided with a circle first
Annular groove, is cast with the first annular inserts of nylon material in first annular groove, be evenly equipped with the opposite side wall of matrix many
The individual first through hole communicated with first annular groove, first through hole is provided with taper hole section, in first through hole and taper hole section
The first inserts of nylon material is cast with, the first inserts is an overall structure with first annular inserts, is added on the periphery of matrix
Work has multiple first teeth, is machined with multiple second teeth on the periphery of first annular inserts simultaneously, multiple first teeth and
Multiple second teeth correspond the complete teeth of composition.
First annular bottom portion of groove on matrix is provided with second annular groove of circle, and the opening of the second annular groove is narrow, bottom
Portion's width, is cast with the second annular insert of nylon material in the second annular groove, the second annular insert and first annular inserts are
One overall structure.
Transmission gear for electric motor bicycle of the present invention, wherein, the first annular bottom portion of groove on matrix is provided with a ring
Shape boss, annular boss extend into the inside of first annular inserts.
Transmission gear for electric motor bicycle of the present invention, wherein, the first annular bottom portion of groove on matrix is evenly equipped with multiple
The second through hole communicated with installing hole, is cast with the second inserts of nylon material in the second through hole, the second inserts with it is first annular
Inserts is an overall structure.
After using above structure, compared with prior art, transmission gear for electric motor bicycle of the present invention has advantages below：Due to
The intersection of the matrix periphery wall of transmission gear for electric motor bicycle of the present invention and a side wall is provided with the first annular groove of a circle, and first
The first annular inserts of nylon material is cast with annular groove, multiple first teeth are machined with the periphery of matrix, first
Multiple second teeth, multiple first teeth and multiple second teeth one-to-one corresponding groups are machined with the periphery of annular insert simultaneously
Into complete teeth, that is to say, that each complete teeth is made up of iron and steel material quality and nylon material two parts, iron and steel material
The teeth of matter have the advantages that intensity is high, and the teeth of nylon material have the advantages that noise is little, therefore, electric motor car of the present invention is passed
Noise less advantage moving gear is provided with higher intensity, work simultaneously when, while the first inserts can prevent first annular embedding
The effect that part rotates with respect to matrix and moves axially.
The effect of annular boss is：In teeth stress, prevent first annular inserts from moving axially with respect to matrix.
The effect of the second inserts is：In teeth stress, the first annular inserts for preventing nylon material occurs with respect to matrix
Rotate, serve the effect of anti-rotation.
The effect of the second annular insert is：In teeth stress, the first annular inserts of nylon material can be prevented relative
Matrix is moved radially.
