Abstract
The present invention relates to transmission parts technical field more particularly to a kind of herringbone bears.The Main to improve herringbone bear 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, the abrasion for greatly reducing herringbone bear effectively raises the service life of herringbone bear.Present invention is mainly used for herringbone bears.
Description
Technical field
The present invention relates to transmission parts technical field more particularly to a kind of herringbone bears.
Background technique
In transmission parts technical field, as service life of the people to machinery equipment requires increasingly longer, double helical tooth
Crop rotation is main rotatable parts, proposes higher requirement to its wearability and self-lubricating property, and current main way is
Hard chrome is heat-treated or plated to steel, but it is still not wear-resisting, so simple conventional material is increasingly difficult to meet in service life side
The requirement in face.
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 herringbone of self-lubricating shape
Gear.
Technical scheme is as follows:
The inside of herringbone bear, institute is arranged in a kind of herringbone bear, including metal layer and wear-resisting lubricant layer, the metal layer
The outside that metal layer is arranged in wear-resisting lubricant layer is stated, the wear-resisting lubricant layer includes skeleton and filler, and the skeleton is in honeycomb,
The filler is arranged in skeletal internal hole, the chemical composition and mass percent of the metal layer are as follows: cobalt≤0.1%, manganese
0.1-0.3%, nickel 0.2-0.5%, aluminium 0.012-0.03%, carbon 0.25-0.36%, chromium≤0.06% and titanium 0.08-0.09%,
Remaining content is iron.
Further, the material of the skeleton be aluminium oxide ceramics, the skeleton with a thickness of 2.5-3mm.
Further, the material of the filler is graphite.
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 the abrasion of herringbone bear, effectively raises herringbone
The service life of gear.
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 herringbone bear, including metal layer and wear-resisting lubricant layer, the metal layer are set
Set in the inside of herringbone bear, the wear-resisting lubricant layer is arranged in the outside of metal layer, the wear-resisting lubricant layer include skeleton and
Filler, the skeleton are in honeycomb, and the filler is arranged in skeletal internal hole, and the material of the skeleton is aluminium oxide pottery
Porcelain, the skeleton with a thickness of 2.5-3mm.The material of the filler is graphite.The chemical composition and quality hundred of the metal layer
Divide ratio are as follows: cobalt≤0.1%, manganese 0.1-0.3%, nickel 0.2-0.5%, aluminium 0.012-0.03%, carbon 0.25-0.36%, chromium≤
0.06% and titanium 0.08-0.09%, remaining content are 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.
