Drive roller, in particular for edge trimmers

Abstract

The invention relates to a drive roller (1), in particular for edge trimmers, in particular for use in the production of metal sheets and in particular in the area of plate or hot strip production, comprising a hub part (2), which is provided with a journal, and a running roller (4), which can be connected to the journal, wherein the running roller is formed with one or more channels for guiding a cooling fluid.

Description

TECHNICAL FIELD[0001]The invention concerns a driving roll, especially for edge trimmers for use in the production of plate, and in this regard, especially hot plate or strip in the heavy plate range or in the hot rolled strip range.PRIOR ART[0002]Driving rolls are used especially in edge trimmers for working plate, with the driving rolls being used for conveying plate in the plate working plants. DE 35 42 007 A1 and WO 01 / 36294 A1 disclose driving rolls used for this purpose. In edge trimmers, the driving rolls are used especially for conveying or straightening plates in shears suitable for edge trimming and / or slitting or cutting plates to length. The use of driving rolls of this type is well known for the working of cold plate. In this regard, the driving rolls are arranged in pairs and guide a plate to be conveyed between them. The driving rolls are set against the plate, and the plate can be conveyed due to the driven rotation of the driving rolls.[0003]During the working of ho...

AI Technical Summary

Benefits of technology

[0005]In accordance with the invention, this objective is achieved by a driving roll with the features of claim 1, wherein the driving roll is designed especially for edge trimmers, especially for use in the production of plate or strip, and here especially in the heavy plate range or in the hot rolled strip range, with a hub part that is provided with a journal and with a running roller that can be joined with the journal, wherein the running roller is designed with a channel or several channels for conveying a cooling fluid. This has the advantage that it is possible to realize cooling of the surface of the running roller, so that all together the energy input into the running roller is minimized.

[0007]It is advantageous is the channels have a star-shaped orientation or are uniformly distributed on the circumference of the running roller. This makes it possible to provide a favorable distribution of the channels, which results in optimized cooling of the surface of the running roller.

[0009]It is also advantageous if first connecting channels and second connecting channels are provided, such that the first and second connecting channels are connected by essentially annular channels.

[0011]In accordance with another idea of the invention, it is advantageous if the journal is mounted in a bearing housing, and the bearing housing also has fluid channels for cooling by means of a fluid.

Problems solved by technology

The continuous input of energy into the driving rolls causes them to overheat, and they thus lose the ability to function properly or they suffer a defect that can ultimately lead to their destruction.
