SU1539566A1 - Method of machining the surface of rolling-contact bearings and parts thereof prior to lubrication - Google Patents

Abstract

The invention relates to physico-chemical methods and means of cleaning the surfaces of objects made of metals, ceramics, plastics and other solid materials. The purpose of the invention is to improve the cleaning performance of the treated surface through a one-time complex mechanical, thermal and chemical effects. The rolling surfaces of the bearings are washed, dried and blown with a stream of gaseous hydrogen gas in air. Due to the self-initiation of the gas mixture when contacted with fatty contaminants, the surface cleaning process is simplified.

Description

The invention relates to physicochemical methods and means of cleaning the surfaces of objects made of metals, ceramics, plastics and other hard materials, and can be advantageously used to treat the surfaces of rolling bearings and their parts before lubrication.

The purpose of the invention is to increase the productivity of surface treatment of bearings and their parts before lubrication by means of a comprehensive one-time mechanical, chemical and thermal effect on the contaminants of various origins.

The method is carried out as follows.

The product to be treated, after washing and drying, is exposed to a stream of a stream of gaseous hydrogen in air. Gas mixture in

contact with fatty contaminants enters into the chemical reaction of the compound, accompanied by a high intensity explosion. In this case, the explosion does not occur simultaneously over the entire surface of the product being processed, but by micro-segments, since the conditions optimal for the reactions of the compound are not formed over the entire area at once, but depending on the specific percentage of hydrogen in air and the state of fat at each time point. contamination. The passing process of a sequence of explosions is decreasing in time and is perceived by hearing as a crackling of fading intensity. During each single microexplosion, a thermal impulse, a shock wave, a gas jet stream, and also water formed as a result of the reaction

products, promote the removal of all kinds of contaminants from the treated surface of the product. At the end of the process of a series of microexplosions, the blowing of the product with a stream of hydrogen is stopped and the necessary lubricant is applied to the surface treated by the proposed method.

Using the proposed method of machining the surfaces of rolling bearings and their parts before lubricating and cleaning objects of other purpose from contamination provides (compared to the known methods, the complex mechanical, thermal and chemical effect on the surface being processed increases productivity of the process (due to self-initiation of the gas mixture during

"Contact with fatty contaminants), and as a result, the process of cleaning the treated surface is simplified.
