TURBO-COMPRESSOR Russian patent published in 1999 - IPC

FIELD: manufacture of compressors. SUBSTANCE: turbo-compressor has housing with thrust shoulder inserted in it, stack including stator and rotor parts and end plate closing the housing on one side. turbo-compressor is also provided with shaft carrying the rotor part; trunnions of this shaft projecting to the left and to the right are mounted in bearing brackets located outside housing. Shaft is mounted in radial and radial-thrust bearings installed in bearing brackets. Brackets are secured on end sections of rotor part of stack projecting from housing. Centering the stack in radial direction is effected by means of holes made in area of thrust shoulder and in end plate; centering in axial direction during operation is effected by means of thrust shoulder of housing and radial-thrust bearing. End of stator part of stack having lesser diameter and bracket having larger diameter are connected by means of adapter. EFFECT: enhanced accuracy of centering of rotor part in stator part; enhanced operational reliability of turbo-compressor. 3 cl, 1 dwg
