Pulp roller

The invention relates to a spreader roller with or without elastic cover with fixed or * adjustable curvature for flexible textile-> Paper or plastic sheets, consisting of a curved axis and pipe sections arranged at a short distance on this axis, the pipe sections on flexible ones Store support rings and are supported by rolling bearings on the axis and surrounding the rolling bearings Grease chambers are sealed to the outside against leakage of grease or oil by sealing rings.

In the known spreader rolls of the type shown, the Nilos rings or cover or sealing disks limit the grease space of the roller bearing, which after the assembly of the spreader roller is not or not without further is accessible. The Nilos rings are in direct contact with the roller bearing and seal the grease space against the leakage of oil to the outside. The running time of the spreader roller is essentially of the Volume of the fat that can be introduced into the fat space and the effectiveness of the sealing of the fat space against

affects the leakage of oil. With this training, only a small amount of fat could get into the fat space be introduced.

From DE-OS 33 24 160 it is known to enlarge the grease space of the rolling bearing in that between the sealing ring and the roller bearing an additional receiving ring is arranged. The fat space is through it enlarged by the width of the recording ring.

This guarantees over a relatively long period of time that the wear surfaces of the rolling bearing Sufficient grease is available, which significantly increases the service life of a spreader roller will.

15th

The disadvantage of all known spreader rolls is that they cannot be determined with absolute certainty is when the ball bearings heat up excessively, which generally occurs when there is a lack of grease.

This has already resulted in unwanted downtimes. For rollers with an elastic Coating there is a risk that the elastic coating will burn through and parts of it into the subsequent one Press arrive.

25th

The invention is based on the object of designing a spreader roller of the type shown in such a way that that unwanted downtimes can be avoided and, if necessary, a targeted relubrication of a specific one Rolling bearing is possible without difficulty.

According to the invention, this object is achieved in that each roller bearing is assigned a thermal monitoring system for displaying the temperature rise and a lubricant supply line.
5

Each thermal monitoring system is expediently connected to one Central display panel connected, which has an optical and / or acoustic warning system, if necessary also in the form of a remote display. There is the possibility of transferring from the Therrao

lines leading to the display board in *

Cavity of the axle or on the outside of the axle f

c to lead in a groove. |

In an embodiment of the invention, the lubricant supply line is located between the outlet located on the roller bearing and a circumferential grease channel is arranged in the bearing bush, with the ».

Fat from the fat duct into the fat compartment in the Lajf gerbuchse one or more lubrication hole (s) can be arranged.

Further developments of the invention are in the remaining ^ indicated against subclaims.

The invention eliminates unwanted downtimes as a result of excessive heating of the rolling bearings * avoided. The thermal monitoring of each individual;

Rolling bearing enables an exact overview of;

the thermal state. Di- invention shows the same-

An embodiment of the invention is shown in the drawing and is described in more detail below. Show it:

In the breakthrough in the wall is the line 3 with a Protective cover 12 provided.

A lubricant feed line is attached to each roller bearing 1 6 connected. Between the outlet of the lubricant supply line located on the roller bearing 1 6 and the bearing bush 7 a circumferential grease channel 8 is arranged, of which three lubrication bores 9 lead to fat compartment 13. The grease space 13 is protected against leakage by a sealing ring 14 (iSfilosring). Grease or oil sealed to the outside. To enlarge the fat space 13 is between the roller bearing 1 and the D: .entring 14, a spacer ring 15 is arranged.

The lubricant supply lines 6 are on both sides led out of the axis 5 and combined in each case in an end bracket 16. From these end brackets 16 from the relubrication of the rolling bearings 1 takes place,
