Abstract
The invention discloses an automobile transmission gear which comprises a gear body and a plurality of gear teeth arranged on the outer circumference of the gear body. A first wear-resisting layer is arranged on the outer surface of each gear tooth, a second wear-resisting layer is arranged on the outer surface of each first wear-resisting layer, a third wear-resisting layer is arranged on the outer surface of each second wear-resisting layer, and a shaft hole is formed in the center of the gear body. Therefore, the automobile transmission gear is quite good in wear-resisting performance and long in service life, and stable operation of an automobile transmission system is guaranteed.
Description
Technical field
The present invention relates to gear technique field, particularly relate to a kind of vehicle transmission gear.
Background technique
Gear industry has obtained develop rapidly in China.Gear is the intermeshing mechanical parts that have tooth of energy, and the application of gear in transmission occurred very early.An important use of gear is to be used in the transmission system of automobile, and on existing vehicle transmission gear, the wear-resisting property of teeth is not good, and working life is short, and usability is bad.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of vehicle transmission gear, has good wear-resisting property, long service life, thus guaranteed the stable operation of car transmissions.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of vehicle transmission gear is provided, comprise: gear body and be arranged on a plurality of teeth on described gear body excircle, on the outer surface of described teeth, be provided with the first wearing layer, on the outer surface of described the first wearing layer, be provided with the second wearing layer, on the outer surface of described the second wearing layer, be provided with the 3rd wearing layer, the center portion of described gear body is provided with axis hole.
In a preferred embodiment of the present invention, the thickness sum of described the first wearing layer, the second wearing layer and the 3rd wearing layer is more than or equal to 50 microns.
In a preferred embodiment of the present invention, described the first wearing layer adopts vanadium carbide coating.
In a preferred embodiment of the present invention, described the second wearing layer and the 3rd wearing layer all adopt titanium nitride coating.
The invention has the beneficial effects as follows: vehicle transmission gear of the present invention, there is good wear-resisting property, long service life, thus guaranteed the stable operation of car transmissions.
