Abstract
The invention discloses an automobile gear structure which comprises a gear body and a plurality of teeth arranged on the outer circumference of the gear body. The gear body is provided with a central shaft hole, the outer surfaces of the teeth are provided with a composite wear-resisting coating which sequentially comprises a zirconium carbide wear-resisting coating, a tungsten carbide wear-resisting coating and an aluminium oxide wear-resisting coating from inside to outside, and a key groove is formed in the central shaft hole. The automobile gear structure is simple and reasonable, good in wear resistance and long in service life.
Description
Technical field
The present invention relates to gear technique field, particularly relate to a kind of automobile gear structure.
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 as gearbox gear, the wear-resisting property of existing this gear 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 automobile gear structure, simple and reasonable, and wear resistance is good, long service life.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of automobile gear structure is provided, comprise: gear body and be arranged on a plurality of teeth on described gear body excircle, on described gear body, be provided with central shaft hole, on the outer surface of described teeth, be provided with composite anti-wear coating, described composite anti-wear coating from inside to outside comprises zirconium carbide wear resistant coating, tungsten carbide wear-resistant coating and aluminium sesquioxide wear resistant coating successively, and described central shaft hole place is provided with keyway.
In a preferred embodiment of the present invention, the thickness of described zirconium carbide wear resistant coating is 12 ~ 15 microns.
In a preferred embodiment of the present invention, the diameter of described central shaft hole is the outside diameter of gear 0.2 ~ 0.3 times.
