Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of interior flower of automotive electronics servo steering system
The left end of key worm screw, including ontology 1, the ontology 1 is equipped with integrally formed first axle portion 2, the right side of first axle portion 2
End is equipped with integrally formed second axle portion 3, and the right end of second axle portion 3 is equipped with integrally formed third axle portion 4, and
The right end of the third axle portion 4 is equipped with integrally formed variable diameter interconnecting piece 5, and the right end of the variable diameter interconnecting piece 5 is equipped with one
4th axle portion 6 of forming, the right end of the 4th axle portion 6 are equipped with integrally formed stop collar 61, and the stop collar 61
Right end be equipped with integrally formed secondary lantern ring interconnecting piece 7, the right end of the pair lantern ring interconnecting piece 7 is equipped with integrally formed main lantern ring
The right end of interconnecting piece 8, the main lantern ring interconnecting piece 8 is equipped with integrally formed 5th shaft interconnecting piece 9.
Wherein, the left end of the ontology 1 offers integrally formed mounting hole 21, and the right end of the ontology 1 offers one
Body formed axis hole 11, the surrounding of 11 inner cavity of axis hole are uniformly equidistantly equipped with integrally formed spline 12, are convenient for the worm screw
With driving axis connection, integrally formed dust-proof cushion mounting groove 62 is offered between the 4th axle portion 6 and stop collar 61, is convenient for
The installation of dust-proof cushion, so that dust is avoided to enter the junction of worm screw and turbine, so that causing the service life of worm screw reduces, institute
Variable diameter interconnecting piece 5 is stated in horn-like structure, thus ensure that the intensity of the worm screw, the outer rim of the pair lantern ring interconnecting piece 7
