Abstract

A hybrid radial thrust bearing consisting of a shaft, a housing, permanent magnets with a C-cross section, divided porous bushes, permanent cylindrical magnets and a magnetic fluid in which permanent magnets with a C-section (3) are mounted on the end pin (1a) of the shaft (1) ) with the arms directed towards the housing socket (2), separated by non-magnetic spacers (6), and inside these magnets (3) are divided porous acetabulars (4), adhering with external cylindrical surfaces to the housing socket (2). The magnetic liquid (5) is located in radial gaps formed between the ends of the arms constituting the N and S poles of the C-section magnets (3) and the cylindrical surface of the socket in the housing (2). In the recess made on the end face of the shaft end (1a) of the shaft (1) and in the recess made on the face of the socket in the housing (2), cylindrical permanent magnets (7, 8) are axially polarized and aligned with each other with polar poles. A flat air gap (a) exists between the end face (1a) of the shaft (1) and the end face of the seat in the housing (2).
