Heatable roller's bearing heating controlling method for paper industry, involves supplying oil as cooling medium to cooling channel, where oil is provided for cooling connecting piece, which is used for supply of used oil given for heating

The method involves forming a cooling channel (13) between heating oil channels (10, 11) and a support (2) at an axle (3) for a thermal roller. Oil is supplied as a cooling medium to the cooling channel, where the oil is provided for cooling a rotatable connecting piece (4), which is used for the su...

Beschreibung
Zusammenfassung:	The method involves forming a cooling channel (13) between heating oil channels (10, 11) and a support (2) at an axle (3) for a thermal roller. Oil is supplied as a cooling medium to the cooling channel, where the oil is provided for cooling a rotatable connecting piece (4), which is used for the supply of used oil given for heating. The oil is derived from the cooling channel at the axle at an opposite side. The cooling channel is isolated against the oil provided for heating. The oil is collected by the surface of the axle. An independent claim is also included for a device for controlling heating of bearings for heatable rollers, which are used in a paper industry. Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Kontrolle einer Aufheizung von Lagern für heizbare Walzen, die in der Papierindustrie für verschiedene Zwecke verwendbar sind. Bei dem Verfahren wird an einer Achse (16) für eine Thermowalze (3) mindestens ein Kühlkanal (13) zwischen Aufheizölkanälen (10, 11) und einem Lager (2) gebildet, dem als Kühlmedium Öl zugeführt wird, das zum Kühlen eines drehbaren Anschlussstücks (4) vorgesehen ist, welches für die Zuführung des zu verwendenden zum Aufheizen bestimmten Öls verwendbar ist. Der Kühlkanal (13) wird gegen das zum Aufheizen bestimmte Öl isoliert.
