DRIVE CONICAL BUSHING FOR THRUST BEARING Russian patent published in 2019 - IPC F04D29/04 F04D29/20 

FIELD: non-displacement compressors and pumps.

SUBSTANCE: group of inventions can be used in horizontal pumps to counteract the axial force created during pump operation. Thrust bearing is designed to reduce axial displacement of shaft and comprises fixed axial bearing, thrust disc located adjacent to axial bearing, and drive conical bushing. Thrust disk has central passage. Drive conical bushing has inner surface in contact with shaft and outer surface in contact with central passage of thrust disc. Central passage of the thrust disc has a stepped profile, while the outer surface of the driven conical bushing is conjugated with the stepped profile of the central passage.

EFFECT: inventions are aimed at perfection of device of attachment of thrust disc to shaft to exclude excessive vibration of shaft and as consequence of connection damage.
