CONTACTLESS METHOD OF CONTROLLED HYDRAULIC MAGNETIC BEARING AND TREATMENT DEVICE FOR ITS IMPLEMENTATION (VARIANTS) Russian patent published in 2017 - IPC B08B3/10 

FIELD: technological processes.

SUBSTANCE: method is performed by simultaneously acting on the bearings guided traveling magnetic fields and turbulent flow of cleaning liquid. Traveling magnetic fields in the cleaning chamber are created by movement in a horizontal plane parallel to the bearing plane of rotation of the magnetic fields from the respective sources of magnetic fields. Traveling magnetic field moves in the space in the forward and backward directions with an amplitude and frequency which are determined respectively to changing intensity and velocity of movement of the original magnetic fields. Jets of cleaning fluid, which is used as aqueous polar solutions, nonpolar hydrocarbon substances - aviation kerosenes, gasolines or mixtures thereof, as well as mixtures thereof - without heating or preheated, is supplied under pressure directly into the path of rolling bearings. The induced by magnetic fields hitless running speed rotation of free rings and bearing parts, creates a turbulent flow of washing liquid, which in combination with the action of the magnetic fields of traveling beyond endure particle contamination as a bearing metal and non-metal origin. Quality control is carried out simultaneously with the purification and drying of bearings by vibration sensors and/or noise with a spectrum analyser. The particles of dirt are removed from the cleaning chamber by filtration washing liquid.

EFFECT: purification efficiency, simultaneous treatment of large quantities and different sizes of bearings from contamination of various origins.
