Pressure roller for textile machines

Abstract

A pressure roller for textile machines, in particular for a texturing machine, is provided. A covering ( 3 ) is preferably arranged over an intermediate sheath ( 4 ) on a support sheath (S). The support sheath ( 5 ) is rotatably supported via a deep groove ball bearing ( 1 ) on a carrying axle ( 2 ). For cost-effective manufacturing of a pressure roller, a standardized deep groove ball bearing ( 1 ) that has at least an outer bearing race ( 6, 7 ) and balls ( 9 ) that roll on the ball grooves ( 10, 11 ) of the bearing race ( 6, 7 ) is proposed, the outer bearing race ( 6 ) of which carries the support sheath. The standardized deep groove ball bearing amounts to at maximum 80 percent of the axial extension of the support sheath ( 5 ).

What is claimed is:  
     
         1 . Pressure roller for textile machines comprising a covering made of plastic or rubber arranged on a support sheath, wherein the support sheath is rotatably supported via a deep groove ball bearing on a carrying axle, said ball bearing is a standardized deep groove ball bearing that has at least an outer bearing race and balls that roll on a ball groove of the outer bearing race, the outer bearing race arranged to carry the support sheath, the support sheath having an inwardly projecting central section which receives the outer bearing race, and side sections adjacent to the central section are thin-walled and are adapted to receive grinding arbors.  
     
     
         2 . Pressure roller according to    claim 1   , wherein the side sections have an inner diameter which is larger than an inner diameter of the middle section.  
     
     
         3 . Pressure roller according to    claim 1   , wherein the side sections are provided with cylindrical shoulders which have identical inner diameters adapted to receive the grinding arbors.  
     
     
         4 . Pressure roller according to    claim 2   , wherein the side sections are provided with cylindrical shoulders which have identical inner diameters adapted to receive the grinding arbors.
