Abstract
The present invention relates to transmission parts technical field more particularly to a kind of lead screws.The Main to improve lead screw 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 is arranged in the gap of skeleton by the way that skeleton is arranged outside metal layer, and filler, and skeleton has preferable wearability, and the filler in skeleton has preferable lubricity, greatly reduces the abrasion of lead screw, effectively raises the service life of lead screw.Present invention is mainly used for lead screws.
Description
Technical field
The present invention relates to transmission parts technical field more particularly to a kind of lead screws.
Background technique
In transmission parts technical field, as service life of the people to machinery equipment requires increasingly longer, lead screw work
For main rotatable parts, higher requirement is proposed to its wearability and self-lubricating property, current main way is to steel
It 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
It is required that.
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 silk of self-lubricating shape
Thick stick.
Technical scheme is as follows:
The inside of lead screw, the resistance to tribology is arranged in a kind of lead screw, including metal layer and wear-resisting lubricant layer, the metal layer
The outside of metal layer is arranged in slip layer, and the wear-resisting lubricant layer includes skeleton and filler, and the skeleton is in honeycomb, the filler
It is arranged in skeletal internal hole, the chemical composition and mass percent of the metal layer are as follows: tungsten≤0.025%, manganese 0.1-
0.3%, nickel 0.55-0.8%, aluminium 0.001-0.02%, carbon 0.31-0.42%, chromium≤0.08% and molybdenum 0.02-0.2%, remaining
Content is iron.
Further, the material of the skeleton be aluminium oxide ceramics, the skeleton with a thickness of 0.5-1.2mm.
Further, the material of the filler is graphene.
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 lead screw, effectively raises making for lead screw
Use the 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 lead screw, including metal layer and wear-resisting lubricant layer, the metal layer setting exist
The inside of lead screw, the wear-resisting lubricant layer are arranged in the outside of metal layer, and the wear-resisting lubricant layer includes skeleton and filler, described
Skeleton is in honeycomb, and the filler is arranged in skeletal internal hole, and the material of the skeleton is aluminium oxide ceramics, the skeleton
With a thickness of 0.5-1.2mm.The material of the filler is graphene.The chemical composition and mass percent of the metal layer are as follows:
Tungsten≤0.025%, manganese 0.1-0.3%, nickel 0.55-0.8%, aluminium 0.001-0.02%, carbon 0.31-0.42%, chromium≤0.08%
With molybdenum 0.02-0.2%, 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.
