Vibration cylinder for compacting concrete

Abstract

The invention relates to a vibration cylinder for an immersion vibrator suited for compacting concrete. The vibration cylinder comprises a housing, which can be closed at one end and inside of which an unbalanced shaft that can be driven is radially and axially guided and supported by antifriction bearings. An antifriction bearing that serves to axially support the unbalanced shaft is supported on the housing in at least one axial direction by a damping element that can be subjected to a high level of deformation work. The damping element can be a shaped element made of an elastomer or plastic

1 . A vibration cylinder for concrete compacting, comprising a housing that can be sealed at one end, in which an imbalance shaft that can be driven is guided and mounted radially and axially by roller bearings, wherein a roller bearing used for the axial support of the imbalance shaft is directly supported in at least one axial direction by a damping element on the housing that is suitable for accepting large-scale deformation work.  
     
     
         2 . The vibration cylinder as recited in  claim 1 , wherein the damping element is a molded element made of an elastomer.  
     
     
         3 . The vibration cylinder as recited in  claim 1 , wherein the damping element is a molded element made of plastic.  
     
     
         4 . The vibration cylinder as recited in  claim 2 , wherein the molded element is a ring.  
     
     
         5 . The vibration cylinder as recited in  claim 2 , wherein the molded element is a cushion.  
     
     
         6 . The vibration cylinder as recited in  claim 1 , wherein the damping element is a screw spring.  
     
     
         7 . The vibration cylinder as recited in  claim 1 , the damping element is a spring washer set.  
     
     
         8 . The vibration cylinder as recited in  claim 1 , wherein the damping element has at least one annular spring.
