Abstract
The present invention relates to transmission parts technical field more particularly to a kind of helical gears.The Main to improve helical gear wearability is steel to be heat-treated or plated hard chrome, but it is still not wear-resisting at present, so simple conventional material is increasingly difficult to meet the requirement in terms of the service life.The present invention outside metal layer by being arranged skeleton, and filler is arranged in the gap of skeleton, skeleton has preferable wearability, and the filler in skeleton has preferable lubricity, helical gear abrasion is greatly reduced, helical gear service life is effectively raised.Present invention is mainly used for helical gears.
Description
Technical field
The present invention relates to transmission parts technical field more particularly to a kind of helical gears.
Background technique
In transmission parts technical field, as service life of the people to machinery equipment requires increasingly longer, helical gear
As main rotatable parts, higher requirement is proposed to its wearability and self-lubricating property, current main way is pair
Steel is heat-treated or is plated hard chrome, but it is still not wear-resisting, so simple conventional material is increasingly difficult to meet in terms of the service life
Requirement.
Summary of the invention
In order to solve the above technical problems, the object of the present invention is to provide a kind of wearabilities and all preferable helical teeth of self-lubricating shape
Wheel.
Technical scheme is as follows:
A kind of helical gear, including metal layer and wear-resisting lubricant layer, metal layer setting are described resistance in helical gear inside
The outside of metal layer is arranged in tribology slip layer, and the wear-resisting lubricant layer includes skeleton and filler, and the skeleton is in honeycomb, described
Filler is arranged in skeletal internal hole, the chemical composition and mass percent of the metal layer are as follows: rare earth≤0.04%, nickel
0.2-0.5%, carbon 0.4-0.5%, chromium≤0.02%, molybdenum 0.05-0.2%, aluminium 0.02-0.06% and titanium 0.08-0.12%,
Remaining content is iron.
Further, the material of the skeleton be aluminium oxide ceramics, the skeleton with a thickness of 1-1.2mm.
Further, the material of the filler is silicon nitride.
The beneficial effects of the present invention are:
It is arranged in the gap of skeleton by the way that skeleton is arranged outside metal layer, and filler, skeleton has preferable resistance to
Mill property, and the filler in skeleton has preferable lubricity, greatly reduces helical gear abrasion, effectively raises helical gear
Service life.
Specific embodiment
With reference to embodiment, the embodiment of the present invention is furthur described in detail.Following embodiment is used for
Illustrate the present invention, but is not intended to limit the scope of the invention.
A preferred embodiment of the invention, the helical gear, including metal layer and wear-resisting lubricant layer, the metal layer setting
In helical gear inside, the wear-resisting lubricant layer is arranged in the outside of metal layer, and the wear-resisting lubricant layer includes skeleton and filler,
The skeleton is in honeycomb, and the filler is arranged in skeletal internal hole, and the material of the skeleton is aluminium oxide ceramics, described
Skeleton with a thickness of 1-1.2mm.The material of the filler is silicon nitride.The chemical composition and mass percent of the metal layer
Are as follows: rare earth≤0.04%, nickel 0.2-0.5%, carbon 0.4-0.5%, chromium≤0.02%, molybdenum 0.05-0.2%, aluminium 0.02-0.06%
With titanium 0.08-0.12%, remaining content is iron.
The above is only the preferred embodiment of the present invention, are not intended to restrict the invention, it is noted that this technology is led
For the those of ordinary skill in domain, without departing from the technical principles of the invention, several improvements and modifications can also be made,
These improvements and modifications also should be regarded as protection scope of the present invention.
