Abstract
A high-temp. resistant self-lubricating bearing using carbon fibres is characterized by that the slots are made on the inner surface of main body and the composite carbon fibre layer is attached on said inner surface to fill the carbon fibres in said slots for self lubrication. Its advantages are low friction coefficient, no noise, high self lubricating performance, and high working temp (500-1000 deg.C).
Description
Technical field:
The present invention relates to machinery manufacturing technology field, is a kind of bearing.
Background technique:
In places such as casting machine, extractors, the bearing that uses at present is ball bearing or needle bearing, comprises matrix and ball or matrix and needle roller, because temperature is very high, environment is abominable, needs often oil injecting lubricating in bearing, the smog that produces during work is bigger, and is very unfavorable to production and workers'health.
Summary of the invention:
The technical problem to be solved in the present invention is not need oil injecting lubricating when disclosing a kind of work, thereby does not produce the bearing of smog.
The scheme of technical solution problem of the present invention is to have fixed groove on the inwall of matrix, is attached with the carbon fiber composite layer on the inwall of matrix, and the carbon fiber composite of carbon fiber composite layer is full of fixed groove.Because the self-characteristic of carbon fiber composite, can selflubricating during with the axle cooperating, do not need oiling, fixed groove can help carbon fiber composite layer and matrix strong bonded.
In order to make the more firm of carbon fiber composite layer and matrix bond, on the inwall of matrix, have fixed hole, the carbon fiber composite of carbon fiber composite layer is full of fixed hole.
Axis, seize phenomenon can not appear in advantages such as it is little that the present invention has a friction ractor, wears away little, noise free, and self-lubricating property is strong, and is wear-resisting, high temperature resistant, and axle do not had wearing and tearing in the using process, work normal temperature reaches 500 ℃, instantaneously reach 1000 ℃, operate steadily.
Description of drawings:
Accompanying drawing is the axial sectional view of bearing of the present invention.
Embodiment:
Bearing of the present invention comprises matrix 1, on the inwall of matrix 1, have fixed groove 3 and fixed hole 4, be attached with carbon fiber composite layer 2 on the inwall of matrix 1, the carbon fiber composite of carbon fiber composite layer 2 is full of fixed groove 3 and fixed hole 4, and wherein fixed groove 3 is swallow tail shaped slots.
Claims (2)
1, a kind of high-temp resistant self-lubricating carbon fibre bearing comprises matrix, it is characterized in that: have fixed groove on the inwall of matrix, be attached with the carbon fiber composite layer on the inwall of matrix, the carbon fiber composite of carbon fiber composite layer is full of fixed groove.
2, self oiling bearing according to claim 1 is characterized in that: have fixed hole on the inwall of matrix, the carbon fiber composite of carbon fiber composite layer is full of fixed hole.
