FIELD: mechanical engineering.
SUBSTANCE: invention relates to devices designed to protect antifriction bearings of rotors of turbopump plants in transportation. Proposed device contains pressure member, end seal unit including stator ring made of soft material and ring sealing lips on rotor installed with clearance between stator ring and tips of lips. Novelty is that end face of pressure member secured on shaft is provided with ring projections, triangular in section, with slots on tops driven into body of ring projection of stator ring. End faces on periphery of stator ring are made at angle to radial direction and stator ring proper is locked from turning, for instance, by radial pins installed in body of stator and stator ring.
EFFECT: improved reliability in operation, reduced overall dimensions and weight.
