Abstract
The invention relates to a bearing production technology, and specially relates to a production technology of a dry friction rolling bearing utilized specially for a nuclear reactor. The dry friction rolling bearing produced by production technology is utilized specially for a nuclear reactor. The production technology is simple. The dry friction rolling bearing produced by production technology has the characteristics of no lubrication, high temperature resistance, corrosion resistance and long service life.
Description
Technical fieldThe present invention relates to a kind of Production of bearing technology, the production technology of the concrete dry friction rolling bearing that relates to the nuclear reactor special use.
Background techniqueIn the nuclear reactor, the clean environment degree is had higher requirement, so the equipment in the nuclear reactor do not allow environment produce is polluted, these equipment are sealed in the nuclear reactor simultaneously.The bearing that uses in these equipment does not allow environment is produced pollution, does not therefore allow to add any type of oiling agent, even allows to use oil-impregnated bearing.Therefore require bearing to have the performance of dry friction, selflubricating.Bearing in the nuclear reactor also needs to work under the condition of high temperature simultaneously.Rolling bearing and the sliding bearing that generally uses is difficult to satisfy this requirement at present.
Summary of the inventionThe objective of the invention is in order to remedy above-mentioned technological deficiency, provide that a kind of nuclear reactor special use is high temperature resistant, the production technology of dry friction rolling bearing.
Technological scheme of the present invention is: the special-purpose dry friction Production of bearing of a kind of nuclear reactor technology comprises outer ring, inner ring, rolling element, retainer; Whole outermost surface is the outer ring, and rolling element is placed on the retainer, and inside is bearing inner race, and the retainer that rolling element is housed is clipped between inner ring and the outer ring.
Described rolling element, material selection silicon nitride or zirconia ceramics material.
Described retainer is selected the PEEK material for use, and processing back cylindrical circularity is less than 0.05 millimeter, and pocket hole error of graduation is less than 0.15 degree.
The process step of the production technology of the special-purpose dry friction rolling bearing of a kind of nuclear reactor is as follows:
1, lasso processing is processed into ring-type with blank, enters cold roll then and expands operation, and the workpiece after the processing is roughly ground, and further carries out hyperfine mill subsequently again and handles.
2, retainer processing machines workpiece earlier, after processing, workpiece is holed, and carries out immersion oil in lubrication hole, and the workpiece that will soak oil cuts open light and handles.
3, rolling element processing is pressed into required form with ceramic ball by the isobaric technology of heat earlier, then workpiece is carried out sintering, and the workpiece behind the sintering is roughly ground processing again, and the workpiece after will roughly grinding at last cuts open light and handles.
