Description

Gear
Technical field:
The present invention relates to the parts for transmission in a kind of electric motor car, be especially a kind of gear.
Background technology:
At present, being used in 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 Being the gear of nylon material, the strength of gear teeth of iron and steel material quality is higher but operationally has the shortcoming that noise is big, nylon material It is low but have the shortcoming that intensity is little that gear operationally has noise.
Summary of the invention:
The technical problem to be solved in the present invention is to provide one, and not only to have intensity higher and operationally have and make an uproar The gear of the less advantage of sound.
The technical solution of the present invention is to provide a kind of gear with following structure: include the matrix of iron and steel material quality, Matrix is provided with installing hole, and wherein, the periphery wall of matrix is provided with a first annular groove of circle, is cast with in first annular groove The first annular inserts of nylon material, the periphery of matrix is machined with multiple first teeth, the periphery of first annular inserts Upper multiple second teeth, multiple first teeth and the multiple second teeth one_to_one corresponding of being simultaneously machined with forms complete teeth；Base It is evenly equipped with the first through hole that multiple and first annular groove communicates on the two side of body, in the first through hole, is cast with nylon material First inserts, the first inserts and first annular inserts are an overall structure, and the first annular bottom portion of groove on matrix is evenly equipped with many Individual the second through hole communicated with installing hole, is cast with the second inserts of nylon material, the second inserts and the first ring in the second through hole Shape inserts is an overall structure.
For solving above-mentioned technical problem, present invention also offers another kind of gear, including the matrix of iron and steel material quality, on matrix Being provided with installing hole, wherein, the periphery wall of matrix is provided with a first annular groove of circle, is cast with nylon material in first annular groove The first annular inserts of matter, the periphery of matrix is machined with multiple first teeth, on the periphery of first annular inserts simultaneously It is machined with the teeth that multiple second teeth, multiple first teeth and multiple second teeth one_to_one corresponding composition are complete；On matrix First annular bottom portion of groove is provided with circle second annular groove, and the opening of the second annular groove is narrow, bottom is wide, the second annular groove Inside being cast with the second annular insert of nylon material, the two side of the first annular groove on matrix is provided with symmetrical Three annular grooves, are cast with the 3rd annular insert of nylon material in the 3rd annular groove, the second annular insert, the 3rd annular are embedding Part and first annular inserts are an overall structure.
After using above structure, compared with prior art, gear of the present invention has the advantage that due to gear of the present invention The periphery wall of matrix is provided with a first annular groove of circle, is cast with the first annular embedding of nylon material in first annular groove Part, the periphery of matrix is machined with multiple first teeth, and the periphery of first annular inserts is machined with multiple second simultaneously The teeth that teeth, multiple first teeth and multiple second teeth one_to_one corresponding composition are complete, say, that each complete teeth Two ends be iron and steel material quality, centre is nylon material, and the teeth of iron and steel material quality have the advantage that intensity is high, nylon material Teeth have an advantage that noise is little, therefore, gear of the present invention is provided with that intensity is higher simultaneously, work time the less advantage of noise.
The effect of the first inserts is: when teeth stress, prevents the first annular inserts of nylon material from occurring relative to matrix Rotate, serve the effect of anti-rotation, be possible to prevent first annular inserts to move radially relative to matrix simultaneously.
The effect of the second inserts is: when teeth stress, prevents the first annular inserts of nylon material from occurring relative to matrix Rotate, serve the effect of anti-rotation.
Second annular insert, the effect of the 3rd annular insert be: when teeth are by radial component, is possible to prevent nylon material The first annular inserts of matter moves radially relative to matrix.
