Claims

[Scope of utility model registration request]

It supports the rotating shaft from below in correspondence with the upper half bearing, has a pocket for high pressure oil on the bearing surface, and has multiple bearing pads with pressure oil holes penetrated from below.These bearing pads are each fixed to the top surface. , an axial support protrusion is provided at the bottom, a plurality of pad receivers are passed through from one end through which the pressure oil hole communicates with the pressure oil hole of the bearing pad, and the upper half bearing is connected from below to the pressure oil hole that communicates with the pressure oil hole of the bearing pad. a lower half support frame which is connected to the bearing box and fixed in the bearing box and supports each of the pad receivers from below so as to be rotatable along the outer diameter surface of the rotating shaft with its support protrusion; It is oil-tightly fixed with a pipe flange at the inner end, and a flexible pipe is connected to the external pipe flange at the outer end, and high pressure oil from this flexible pipe is passed through the pressure oil hole in the pad receiver. High-pressure oil pipe flange joint, attached to the upper half bearing and one end of the lower half support frame,
A seal ring movably fitted on the rotating shaft is supported in a floating state in an internal annular groove to seal the shaft. A holding plate is provided with a flange hole that passes through the outer periphery of the inner end pipe flange and is enclosed with a gap, and is attached to the outside of the flange hole of this holding plate, and is attached to the inner end pipe of the high pressure oil pipe flange joint. The rotary shaft is equipped with an elastic seal member that closely contacts the outer periphery of the flange, and a presser plate that fixes the elastic seal member to the retainer plate, and high-pressure oil is supplied from the outside so that each of the bearing pads can be moved in an oil-tight manner, and the rotating shaft is rotated. A tailing pad bearing device that enables floating.
