Static-pressure oil chamber a5, static-pressure oil chamber b10 pass through the control of Bearing outer flow controller respectively and pass through static-pressure oil chamber throttle orifice
A21, static-pressure oil chamber throttle orifice b22 oil stream amount, it can be achieved that dynamic regulation oil pocket internal pressure, obtains corresponding bearing capacity.
Tilting bush a7, tilting bush b12 pass through the swing of tile fragment respectively, form suitable oil film wedge, to adapt to different loads
Lotus situation.
Shaft 1 bear axial load when, axial load is passed into runner plate 3, by runner plate 3 respectively with static-pressure oil chamber
A5, static-pressure oil chamber b10, tilting bush a7, the oil film carrying between tilting bush b12, transmit the force to thrust bearing.
By the above-mentioned means, since cover board 2 and the static-pressure oil chamber b10 on shell 4 are opposite with the position tilting bush a7, static pressure oil
Chamber a5 is opposite with the position tilting bush b12, and when bearing working, axial load will be combined by static-pressure oil chamber b10 with tilting bush a7
Carrying, static-pressure oil chamber a5 and tilting bush b12 sharing lood improve to be provided simultaneously with the carrying advantage of static pressure and dynamic pressure
Antiwhip.
