Press roller for use in press device in e.g. calender for formation of press gap for dehydration of paper in machine for manufacturing and/or smoothing paper, has supporting surface comprising multiple recesses without oil supply point

摘要

The roller has a circular roller casing (3) supported at a supporter (2) via a partial hydrodynamic lubricating supporting element (4) that is pressed against an inner circumference surface of the roller casing. The supporting element has a supporting surface (6) that faces an inner circumference surface of the roller casing. The supporting surface extends in a rolling direction (5) of the casing. The surface has an oil supply point that serves for implementing hydrodynamic lubrication, which takes place, during operation. The surface has multiple recesses without the oil supply point.
