The invention relates to machine-building, in particular to self-adjusting pads of bearings, and can be used in high-speed compressors, gas and steam turbines, pumps and other rotor machines. A thrust bearing includes body with channels for oil supply to inter-pad space of bearing and takeoff of oil to discharge, oil removal scrapers installed in inter-pad space. According to the invention at least one of groups of channels of oil cooling is placed in thermally not stressed zone of the pad. Oil removal scrapers have at least two links that provide presence at least of two not connected cavities in inter-pad space, due to that mixing of oil supplied to bearing and hot lubrication oil is prevented. Besides that, pads are reversible and/or non-reversible. Complex use in one bearing of reversible and non-reversible pads provides effective operation of bearing at direct direction of rotation of rotor and at reversed rotation as well. The invention provides increase of bearing capacity of thrust bearing. |
