Structural assembly for completing hub of opening roll - has unit with garniture ring and tube pressed axially on hub

摘要

Structural assembly has garniture ring and tube which is pressed axially on the hub and incorporates outer rotating surface for the inner bore of the garniture ring and rotating collar serving as axial stop for the garniture ring. The tube has outer thread at its end facing away from the rotating collar. The outer diameter of the thread is smaller than the rotating fitting surface. The inner bore of the garniture ring is equipped with inner thread at one of its axial ends. The thread fits into the outer thread of the tube. The length of the garniture ring corresponds roughly to the axial length of the fitting surface with the addn. of the outer thread of the tube. The assembly of the parts begins with pressing the tube on the hub. ADVANTAGE - Permits the use of the same garniture ring on different hubs and the exchange of the ring takes place in the same way irrespective of the associated hub.
