Fluid-delivery device for shafts

Abstract

The invention relates to a fluid delivery device for shafts, with a shaft-ring section assigned to the shaft, which rotates with the shaft during rotation of the shaft and a ring body arranged around the shaft ring section, fixed during rotation of the shaft, which has an inlet for the fluid, rolling bodies being arranged between the shaft ring section and the ring body, on which the shaft ring section and the ring body are supported and a passage being assigned to the shaft ring section, which is connected to inlet.

1 . A fluid-delivery device for a shaft comprising: 
 a shaft-ring section assigned to the shaft, which rotates with the shaft during rotation of the shaft,    a ring body arranged around the shaft ring section, fixed during rotation of shaft, which has an inlet for the fluid,    rolling bodies arranged between the shaft-ring section and the ring body, on which the shaft-ring section and the ring body are supported, and    a passage assigned to the shaft ring section, which is connected to the inlet.    
   
   
       2 . A fluid-delivery device according to  claim 1 , wherein the rolling bodies are arranged in a flow path of the fluid.  
   
   
       3 . A fluid delivery device according to  claim 1 , wherein the rolling bodies are enclosed in a fluid-tight manner by the shaft-ring section and by the ring body.  
   
   
       4 . A fluid-delivery device according to  claim 1 , wherein the shaft-ring section is designed in several parts.  
   
   
       5 . A fluid-delivery device according to  claim 1 , wherein the shaft-ring section forms bearing surfaces for the rolling bodies.  
   
   
       6 . A fluid-delivery device according to  claim 1 , wherein the ring body forms bearing surfaces for the rolling bodies.  
   
   
       7 . A fluid delivery device according to  claim 5 , wherein the bearing surfaces are arranged at an angle to a longitudinal axis of the shaft, to take up axial and radial forces.  
   
   
       8 . A fluid-delivery device according to  claim 1 , wherein the shaft ring section has an outlet for the fluid, arranged laterally (axially).  
   
   
       9 . A fluid-delivery device according to  claim 1 , wherein the shaft-ring section has at least one essentially axial passage for a fluid line.  
   
   
       10 . A fluid-delivery device according to  claim 1 , wherein the ring body is designed in several parts, preferably being capable of disassembly so that, when the fluid-delivery device is completely installed, at least one seal is accessible by removing a part.  
   
   
       11 . A fluid-delivery device according to  claim 1 , wherein a progressive distributor is provided, which is connected in terms of flow to the shaft ring section and rotates with the shaft.  
   
   
       12 . A fluid-delivery device according to  claim 1 , wherein the fluid delivery device is designed as a central lubrication device for lubrication of joints with lubricants, preferably grease.
