CAGE ARRANGEMENT FOR DEEP-ROLLING ROLLERS
1. A cage arrangement which essentially comprises disc-shaped rollers which are guided in a roller cage arranged on a housing and held in position by a cage plate which is essentially strip-shaped and attached to the housing in a position which is remote from the roller area, wherein the cage plate has a retaining bar which, in the intended installation position, is located in the direction of a roller and has a front surface section which corresponds in terms of the run of the mould to a roller surface which faces the retaining bar.
A cage arrangement comprises substantially flat rollers, which are guided in a roller cage arranged on a housing and are held in position by a substantially strip-like cage metal sheet attached to the housing at a position remote from the roller region. The cage metal sheet has a retaining piece that protrudes in the direction of a roller in an intended installation position and has an end-face region, the shape of which corresponds to that of a roller surface facing the retaining piece.

This application is a National Phase of International Application No. PCT/EP2018/057267 filed on Mar. 22, 2018. This application claims the benefit of European Patent Application No. 17162750.8, filed on Mar. 24, 2017. The entire disclosures of the above applications are incorporated herein by reference.
This disclosure relates to a cage arrangement for work rollers. These are essentially disc-shaped rollers which are guided in a roller cage arranged on a housing and held in position by a cage plate which is essentially strip-shaped and attached to the housing in a position which is remote from the area of the roller.
This section provides background information related to the present disclosure which is not necessarily prior art.
Such cage arrangements are known from the state of the art.
A generic device is described in EP 0 839 607, for example. In this device, a work roller is supported against a pair of rollers and held by a gate plate.
In WO 02/22284 A1, a generic roller cage is described, in which lubricant-storing and discharging materials are used to supply lubricant to the work roller if required.
From EP 1468783 A1, a cage arrangement is known which essentially comprises disc-shaped rollers that are guided in a roller cage arranged on a housing.
In the meantime the rolling processes have become more complex, in particular through better measuring methods and control methods. Work rollers are no longer necessarily symmetrical along their central plane, but instead have contours that enable the optimum support for and dissipation of forces in order to produce the desired contours in an optimum manner and at the same time improve the service life of the rollers. Furthermore, it is desirable to be able to design the housings to be more flexible in different embodiments. It is therefore important that the work rollers are installed correctly. Otherwise, neither can the desired positions be rolled, nor are the rollers adequately supported.
This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.
On the basis of the aforementioned state of the art, the present disclosure is founded on the task of further developing a cage arrangement of the generic type so that it is more or less impossible for work rollers to be installed incorrectly and, in addition, optimum guidance and support of the rollers is provided.
For the technical solution of this task, a cage arrangement with the features of the present disclosure is proposed. Further advantages and features are explained in the subclaims.
According to the disclosure, the cage plate includes a retaining bar. This is located in the intended installation position in the direction of a roller and is provided in the front surface area in such a way that it corresponds there to the shape of the roller surface facing the bar in accordance with the designated purpose. In this way, the roller is held perfectly in position and supported. Furthermore, it is not possible to install the roller the wrong way round, as the mould covering is then no longer present.
In an advantageous manner, the cage plate can have two corresponding retaining bars, both of which are prepared or shaped in the front surface area according to the roller shapes. As a result, a pair of rollers can be arranged and held against the housing with a cage plate. It is of course possible for more than one such formations to be present if the tool is controlled accordingly.
In an advantageous way, the retaining bar is formed at the end of the cage plate. This is implemented as a rule for cage plates which are attached on one side. Otherwise, the cage plate can have retaining bars in the central area.
In an advantageous way, the cage plate is formed from one piece, i.e. the retaining bars are formed in one piece with the cage plate. It is of course also possible to include assembled and even replaceable solutions as part of the disclosure.
According to an advantageous proposal, the cage plate is made of metal, but can also be made of all other materials, as is customary in the state of the art. These include, for example, the use of materials which are suitable for absorbing and dispensing lubricants which can be used at least in the area of the retaining bars. Modular production from different materials is also possible.
In an advantageous way, the cage plate has an adjustable gate in order to optimally position and adjust it relative to the rollers which are to be held in place. According to an advantageous proposal of the disclosure, an adjusting gate can be provided in the form of an end-section deflection of the cage plate, so that adjustment is possible by means of a draw spindle, for example.
In an advantageous way, the cage plate has an adjusting gate in both end sections for adjusting and fixing this.
Further areas of applicability will become apparent from the description provided herein. The description and specific examples in this summary are intend-ed for purposes of illustration only and are not intended to limit the scope of the pre-sent disclosure.
The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.
With the disclosure, a solution that can be produced at low economic expense is provided which optimises the assembly and use of work rollers. Further advantages and features of the disclosure are explained in the description of the figures below:
