CS265067B1 - Method for cleaning bearing balls - Google Patents

Abstract

) The cleaning method is performed by rolling the balls in an inorganic powder, which absorbs the lapping agent residues from the surface of the balls and then falls off spontaneously. The method achieves extreme cleanliness of the bearing balls.

Description

The invention relates to bearing production. Shaax achieving extreme purity of bearing balls after final lappingx.

The cleaning of the bearing balls finished by gluing in petroleum products is carried out using organic solvents and ultrasound. In a simpler case, the beads are washed in a solvent and then wiped by hand in buckskin. This method is physically demanding, unproductive, dangerous from the fire point of view and technically / imperfect. The remnants of the lapping agent as well as the slight hair of the buckskin remain on the balls. Most world manufacturers have already replaced this simple, imperfect method of cleaning with machine cleaning. All types of washing machines used are complex devices. Washing is carried out in organic solvents under ultrasonic treatment. Remnants of washing liquids and their evaporators are removed from the surface of the beads using solvent vapors. Current methods of washing finished balls in ultrasonic scrubbers are powerful but very expensive. Their significant disadvantage is inadequacy from an ecological point of view.

The disadvantages of the above mentioned cleaning methods are overcome by the solution according to the invention. It is based on rolling balls in an inorganic powder. Due to the residual liquid trapping medium remaining on the surface of the beads from the last lapping operation, the powder adheres to the beads. In the further rolling process, the inorganic powder absorbs the lapping liquid. This reduces its adhesion to the bead surface and the powder spontaneously falls off.

The invention is a combination of two physical properties. The first is the ability of the inorganic powder to absorb liquid petroleum products. The second characteristic is the nature of the bond between the glossy surface of the beads and the powder. If there are liquid residues on the surface of the beads, the adhesion of the powder is high. On the other hand, adhesion is very low between dry balls and powder. Therefore, at the beginning of cleaning, the powder is easily rolled onto the beads. As soon as liquid is sucked from the surface of the beads, it spontaneously falls off. The simplicity of the Cleaning Process is its economic efficiency. From the hygienic point of view, the cleaning method is also very advantageous. During cleaning, the beads come into contact only with chemically non-aggressive agents and are thus more resistant to corrosion than the original ones

The cleaning method is carried out as follows. Marbles, ns. whose surface is remnants of the lapping agent fall into the cleaning machine. In the machine there is a layer of inorganic cleaning powder, for example a mixture of calcium carbonate and magnesium carbonate. Upon impact on the powder layer, the beads begin to roll. The rolling is ensured by the construction of the sewage treatment plant. In the part of the rolling of the pawls to the balls adheres. In the next part of the operation the powder wrapping is finished. The ball roll continues. It lasts until the catching agent is absorbed by the powder. In the last stage, the powder falls off the surface of the beads and the beads exit from the processing plant.

Claims (1)

A method for cleaning bearing balls, characterized in that the balls are rolled over the inorganic powder layer, wherein the inorganic powder absorbs impurities from the surface of the beads as scavenger residues, thereby reducing the bond between the surface of the beads and the inorganic powder and gradually dropping them.
