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 (5). 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 structural height of the standardized deep groove ball bearing amounts to at maximum 80 percent of the axial extension of the support sheath (5).
Claims3
Pressure roller for textile machines comprising a covering which is made of plastic or rubber and is arranged over an intermediate sheath 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 is provided with material displacements on at least one side of said central section which are engaged behind the outer bearing race on a side face, and a structural height of the standardized deep groove ball bearing is set at a maximum of 80 percent of an axial extension of the support sheath.
