SUPPORT FOR TURBO-COMPRESSOR ROTOR

摘要

turbo-compressors for turbo-jet engines. SUBSTANCE: proposed support includes rotor, antifriction bearing whose inner race is located on shaft of rotor, stator and bearing ring fitted in this stator and provided with outer race of bearing with roller inside it. Stator and bearing ring have end flanges mounted on one side from bearing; several radially directed rods are smoothly located over circumference; they are rigidly fastened to stator and are slidably connected with end flanges of bearing ring; end flanges of stator and bearing ring are engageable and are slidable in transversal direction relative to rotor axis; maximum distance between sliding surfaces of rods directed towards bearing and rollers of bearing is equal to radius of rollers. EFFECT: enhanced efficiency and reliability; increased service life due to reduced vibrations of rotor and stator due to equally changeable radial clearance between bearing ring and outer race of bearing, dampening rotor vibrations, centering rotor relation to stator; availability of properties ensuring operation of turbocompressor at unbalance of rotor. 2 dwg
