Hydrodynamic radial plain bearing with a very high load-bearing capacity of large turbine sets

Abstract

A plain bearing with a bearing body in which a body, which is to be stored is arranged, is disclosed. The bearing body is surrounded by a supporting body. The bearing capacity is improved by virtue of the fact that the bearing body has a partial joint arranged at an angle in relation to the horizontal. The plain bearing has an active cooling system and an articulated lubrication system.

       18 . A plain bearing, comprising:
 a bearing body in which a body is borne, the bearing body having, seen in circumferential direction, a first channel arranged in a wall of the bearing body at least in places, wherein at least one axial hole is arranged in the wall and passes through the first channel; and   a supporting body surrounding the bearing body.   
   
   
       19 . The plain bearing as claimed in  claim 18 , wherein the bearing body has a second channel and at least one axial hole is arranged in the wall and passes through the first and the second channel. 
   
   
       20 . The plain bearing as claimed in  claim 19 , wherein the second channel is at a distance from the first channel seen in axial direction. 
   
   
       21 . The plain bearing as claimed in  claim 18 , wherein the first channel is incorporated in a loaded bearing shell of the bearing body and is open toward the supporting body, and wherein the first channel, seen in the circumferential direction, is incorporated in a semicircular shape in the wall such that a semicircular groove is effectively formed which extends into an unloaded bearing shell. 
   
   
       22 . The plain bearing as claimed in  claim 19 , wherein the first channel is incorporated in a loaded bearing shell of the bearing body and is open toward the supporting body, and wherein the first channel, seen in the circumferential direction, is incorporated in a semicircular shape in the wall such that a semicircular groove is effectively formed which extends into an unloaded bearing shell. 
   
   
       23 . The plain bearing as claimed in  claim 18 , wherein the first channel has, seen in circumferential direction, bearing pockets at its opposite ends in which at least one injection element is arranged for injection of liquid lubricant to the borne body. 
   
   
       24 . The plain bearing as claimed in  claim 21 , wherein the first channel has, seen in circumferential direction, bearing pockets at its opposite ends in which at least one injection element is arranged for injection of liquid lubricant to the borne body. 
   
   
       25 . The plain bearing as claimed in  claim 18 , wherein the bearing body is in the form of a multiple-surface bearing composed of two half-shells, wherein the first channel is arranged in the loaded half-shell, and wherein a separating joint is arranged at an angle with respect to a horizontal such that one of the bearing pockets is arranged above the horizontal and the other bearing pocket is arranged below the horizontal, seen in cross section. 
   
   
       26 . The plain bearing as claimed in  claim 23 , wherein the bearing body is in the form of a multiple-surface bearing composed of two half-shells, wherein the first channel is arranged in the loaded half-shell, and wherein a separating joint is arranged at an angle with respect to a horizontal such that one of the bearing pockets is arranged above the horizontal and the other bearing pocket is arranged below the horizontal, seen in cross section. 
   
   
       27 . A plain bearing, comprising:
 a bearing body in which a body is borne, the bearing body having, seen in circumferential direction, opposite bearing pockets, wherein injection elements are each arranged in a plurality of rows on the opposite bearing pockets, and wherein the injection elements spray liquid lubricant onto the borne body and into an outlet gap; and   a supporting body surrounding the bearing body.   
   
   
       28 . The plain bearing as claimed in  claim 27 , wherein the injection elements are arranged as a plurality of two rows in the respective bearing pockets, and wherein the injection elements are screwed into the bearing pockets as nozzles. 
   
   
       29 . The plain bearing as claimed in  claim 27 , wherein the injection elements are arranged such that the liquid lubricant is sprayed at right angles onto the borne body, wherein the injection elements are arranged such that the liquid lubricant is sprayed obliquely into an outlet gap of the loaded half-shell, and wherein only the obliquely directed injection elements in one of the bearing pockets are active. 
   
   
       30 . The plain bearing as claimed in  claim 28 , wherein the injection elements are arranged such that the liquid lubricant is sprayed at right angles onto the borne body, wherein the injection elements are arranged such that the liquid lubricant is sprayed obliquely into an outlet gap of the loaded half-shell, and wherein only the obliquely directed injection elements in one of the bearing pockets are active. 
   
   
       31 . The plain bearing as claimed in  claim 29 , wherein the injection elements of the bearing pocket, which is, seen in cross section, arranged under the horizontal when the bearing body is in the fixed state, are active.
