DE2119389C3 - Modular system for the construction of any stand arrangements of roller machines, especially calenders - Google Patents

Description

In order to become even more universal, the invention has the task of establishing an even broader unity * To achieve loan of the components, so that with a given roll diameter usually only one Standard component for the construction of all

roller arrangements, so-called rolling mills, tri-machines of appropriate arrangements required

and Mchrwalzcnanordüngen with the most varied of relative positions of the rollers to each other vei turns.

According to the state of the art, for each of these arrangements, specially made, complete machines built. The rollers Miid with their bearings in a special Frame or stand arranged, which holds all the wholesalers encloses and forms a unit with the entire machine that does not or only under considerable effort can be changed.

A device is also known in which three rollers are mounted in a frame, from iVncn one can be removed a greater distance from the other, so that then only with two WaI-i ν-η can be worked.

A roll stand, in particular for calenders, is also known (German publication i 504 447), which consists of several detachably connected parts, with each roller mander at least four parts belong, soft partially are the same. As usual, the roller bearing stones sit in the recesses of the assembled stand. The parts can be used in different ways to form stands for different Kalanuerisl - apart from a base plate, which ensures the axial fixation.

The invention accordingly consists in that in a system mentioned at the outset without use of a special machine stand the sländcrlcil accommodating the I agcr from the uniformly designed Bearing housings of the roller bearings are built up or made up of unit bearing blocks, each containing a roller bearing.

The actual one-part or multi-part, used in all previously known devices, multiple bearing enclosing stator components can therefore be omitted; they are made by firmly joining the bearing housing or Einhcitslagcrbau-

15 stones replaced.

Ice cream is the simplest possible building block system, namely a system which essentially uses only one unitary element Any structure can be set up.

The ßausteinsystcm consists essentially of one or two pieces each with a roller pull cord Bearing blocks, which are shaped so that a circularly circumscribed polygon is created, the Diameter of the enclosed circle in the

arrangements can be assembled. Fs will therefore almost always be equal to the roll diameter and make it possible to achieve a certain level of storage and
to reduce manufacturing costs.

These known machines have the major disadvantage that they are essentially only in the once defined, can be used for one or a few specific purposes. The latter The modular system for the roll stand already enables greater variability, but has still have the disadvantage that there are different parts with the bearing blocks of the same type on all sides Terminal surfaces are provided so that other identical modules on any side of the first module can be connected.

The sides of the polygon can be of any length; are for practical reasons however, pages of equal length are preferable.

In particular, it is advantageous to choose a square, i.e. square shape for the bearing blocks,
