Guide roll for a web forming machine and methods for manufacturing the corresponding guide roll

Abstract

The invention relates to a guide roll for a web forming machine. The guide roll (15, 15') includes a shell (10) of a sheet material, with end pieces (11) at both of its ends. In addition, in each end piece (11) there is an end plate (13) , with a protruding shaft (14) in it for a bearing arrangement (12) . The end plate (13) and the protruding shaft (14) are arranged as separate pieces. In addition, there is at least one shaped plate piece (19) between the end plate (13) and the protruding shaft (14), separate in the axial direction from the point of contact between the end plate (13) and theprotruding shaft (14). The invention also relates to a method for manufacturing and using the guide roll (15, 15 ').

Description

Guide roll for a web forming machine and method for producing the same technical field The invention relates to a guide roll of a web forming machine, the guide roll comprising: a housing made of sheet material; end elements, at both ends of the housing, for rotatably supporting the guide rolls in bearing arrangements of the web forming machine; and An end plate, in each end element, in which is provided a protruding shaft for connecting said bearing arrangement. The invention also relates to a method for manufacturing the guide roller. Background technique In a web forming machine, such as a paper or board machine, a number of guide rolls are used, eg for supporting a papermaking felt or wire. The covered section of the guide roller is usually small so it is lightly loaded. In addition, there are special guide rolls in the web forming machine, on which only the paper is conveyed. In that case, the linear load on the paper guide roller is around 1KN / m. In known g...

AI Technical Summary

Problems solved by technology

In fact, even if the load requirements are small, the machining requirements determine the configuration and size of the shell and end elements, making guide rollers too bulky and expensive for their working purpose

Also, cast end elements and thin housings are an unsatisfactory combination in terms of vibration

In fact, deflection also occurs in the thin-plate-constructed shell, and this deflection cannot be compensated in the known guide rollers
