DEVICE FOR COOLING AND LUBRICATING BEARINGS Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: device has housing, shaft with dummy axial passageway, ball bearing fitted on the shaft, nozzle rings, oil pump with screw blades, and hydraulic filter with a filtering metallic grid. The end of the shaft is inserted in the inner space of the filter. The shaft has a baffle ring that is rigidly secured to the shaft and mounted inside the pipe line between the pump and filter. The baffle ring has the outer bevelled surface. The nozzle rings have jet nozzle openings. The openings are in communication with the dummy axial passageway through the radial nozzle openings. The cross-section area of each of the jet nozzle openings is greater than the cross-section area of the nozzle opening. The baffle ring is mounted inside the filter sleeve to guarantee face and radial spaces. The jet nozzle openings are inclined to the axes of the respective nozzle rings at acute angles. There is a tangential drain passage in the cover of the filter. EFFECT: improved cooling and lubricating. 4 cl, 3 dwg
