Definitions
- the invention relates to a roller-mounted pressure roller for textile machines, in particular for texturing machines, with an elastic coating which is mounted on an outer ring.
- Such roller-mounted pressure rollers with an elastic cover for transporting or distorting a thread in textile machines are already known.
- the rollers pinch the thread between a delivery unit and the rubber cover.
- the rubber covering For trouble-free transport, the rubber covering must be pressed evenly against the delivery plant.
- the storage of the covering must have a degree of freedom. This degree of freedom must also be relatively large so that the permissible tolerances in the machine frame between the attachment of the delivery mechanism and the attachment of the swivel levers do not become too narrow.
- DE 17 60 142 AI was therefore proposed to store the pressure rollers free-floating, so that in the by their axis of rotation and the axis of the delivery cylinder - 2 -
- the object of the present invention is to propose a pressure roller which can be easily removed from the machine in terms of its structure and without the use of a tool.
- the object is achieved according to the invention with a pressure roller of the type mentioned at the outset in that the outer ring is fastened in a form-fitting manner on the axis of the pressure roller by means of a quick-release fastener which can be released without tool aid. If the lining of the pressure roller is to be reground, the outer ring with the lining can now be easily removed from the axis and then ground. The outer ring can be clamped directly into the corresponding grinding machine. A separate removal of the axis is not necessary.
- the provision of a quick-release fastener also simplifies the construction and assembly of the pressure roller, since there is no need for separate fastening means.
- the quick-release fastener can be formed, for example, by a snap connection. For example, it is possible to hold the outer ring by an outer cover on the axis - 3 -
- roller bearing receiving ring can be made of plastic.
- the quick lock can also be a bayonet or screw lock.
- the axis of the pressure roller is spherical. As a result, no separate pivot axis is required for the oscillating suspension of the pressure roller. By replacing the cylindrical shaft with a spherical shaft, there is also a lower surface load on the pivot bearing. This solution also requires fewer parts and is therefore less expensive.
- FIG. 1 shows a sectional view in exploded view of a pressure roller
- FIG. 2 shows a section through the assembled pressure roller from FIG. 1.
- the pressure roller 10 from FIGS. 1 and 2 has an outer ring 11 which is covered with an elastic cover 12.
- a roller bearing 13 is arranged on the inside of the outer ring 11.
- the outer ring 11 with the cover 12 and the roller bearing 13 can be pulled off an axis 14 for the pressure roller 10.
- the axis 14 has a spherical section 14.1 on which a roller bearing receiving ring 15 can be fitted.
- the unit consisting of outer ring 11, coating 12 and roller bearing 13 is pushed onto the roller bearing receiving ring 15.
- the unit consisting of outer ring 11, cover 12 and roller bearing 13 is fixed to the axis 14 by a cover 17 which can be snapped into the end face of the roller bearing receptacle 15, as shown in FIG. 2.
- the spherical part 14.1 of the axis 14 ensures that the pressure roller 10 can oscillate parallel to the surface of the delivery mechanism, not shown in detail.
- the easily detachable locking connection between the cover 17 and the roller bearing receiving ring 15 enables the outer ring 11 with the cover 12 to be pulled off the axis 14 quickly if the cover 12 has to be reground due to signs of wear.
- the subsequent assembly is also simple and, like pulling off, is possible without tools.
- the roller bearing 13 does not have to be pulled off together with the outer ring 11 and the axle. It could also form a unit with the roller bearing receiving ring 15 and only the outer ring 11 and the cover 12 could be designed to be removable. Instead of a Rastver- bmdunq between the cover 17 and the roller bearing receiving ring
