Title:
MAGNETIC LEVITATION BEARING ASSEMBLY AND COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2017/166911
Kind Code:
A1
Abstract:
A magnetic levitation bearing assembly, comprising a magnetic levitation bearing, a fixation shell (5) and a working clearance adjusting device (8); the magnetic levitation bearing comprises a first iron core (1), a second iron core (2) and a thrust disk (3); the working clearance adjusting device (8) is arranged between a radial inner periphery of the fixation shell (5) and the thrust disk (3) along the radial direction, and between the fixation shell (5) and the second iron core (2) along the axial direction; an axial end of the working clearance adjusting device (8) is abutted against the second iron core (2), an void gap (Y) is provided between the fixation shell (5) and the second iron core (2), an adjustment on the magnetic levitation bearing working clearance is made possible by means of altering the length between two axial ends of the working clearance adjusting device (8), such that the working clearance is consistent with a design value. Further disclosed is a compressor comprising the magnetic levitation bearing assembly. The present invention allows for convenient adjustment on the magnetic levitation bearing working clearance, while effectively avoiding processing errors and risks of coil damage caused by a secondary processing of the magnetic levitation bearing.
