ROLLING BEARING Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: parts of the rolling bearing is connected with anode, and friction zone is affected by the ultrasound. The rate of restoration of worn parts of the friction system is controlled by changing concentration, conductivity, temperature, and composition of the ion-generating fluid by changing the number, structure, and material of the soluble anodes. The pressure inside the inner space of the bearing and speed of motion of friction parts are controlled. The magnitude of the current in the anode circuit and bearing part is programmable and varies from the constant value to the pulse value with changeable frequency, relative pulse duration, and amplitude. The system is provided with pickups that record the conditions of operation of the bearing, its velocity, loading, temperature and so on. The power source can be connected and disconnected externally. The bearing has pickups for recording parameters of the ambient fluid and process. The bearing is provided with sound, light, and digital alarm.

EFFECT: increased durability.
