FIELD: engines and pumps.
SUBSTANCE: proposed delivery oil rotary pump comprises casing and casing cover. Rotor composed of shaft and impeller is arranged between casing and cover. Pump rotor runs in console bearing supports located outside pump casing. Said bearings represent two types of antifriction bearings: spherical two-row roller bearing to take up pump shaft axial load and floating toroidal roller bearing. Both bearings are fitted on the shaft by means of tapered coupling bushes with axial split Impeller is fitted on the shaft with the help of two-sided collet jig with conical sleeves and screws while rotor end seals are fitted on the shaft with the help one-side collet jigs with conical bushes and screws.
EFFECT: reduced noise and vibration, higher reliability and efficiency, longer life
