Embodiment Construction

[0029] referenced below Figure 1 to Figure 18 The present invention is described in detail by way of examples. In all figures, the same technical elements are indicated by the same reference numerals.

[0030] figure 1 The bearing locking device 100 according to the invention is shown in a first exemplary embodiment. It is used to fit at least one bearing 200 onto the roll neck 310 of the roll, to hold the bearing 200 on the roll neck or to release the bearing 200 from the roll neck 310 .

[0031] The bearing locking device 100 has a threaded ring 110 which can be pushed axially onto a roll shoulder 320 of a roll neck 310 . The threaded ring 110 has an axially extending first section 111 with an external thread 112 on its outer side. In addition to the annular first section 111 , the threaded ring 110 also has an annular second section 113 . Usually, the second annular section has a smaller outer diameter than the first annular section 111 , so that a stop 117 is formed ...

Abstract

The invention relates to a bearing locking device (100) and a method for mounting and removing a bearing (200) from a roll neck by means of the bearing locking device. The bearing locking device (100) has a threaded ring (110) that can be slid onto the roll neck. The threaded ring itself has external threads. Stoppers (315, 120') near and away from the roll body are provided on the roll neck to limit the axial movement of the threaded ring (110). The bearing locking device (100) also has a ring nut (130) with an internal thread (132) to be screwed onto the external thread (112) of the threaded ring (110). In order to tighten and loosen the ring nut more reliably and to keep the threaded fastener free from pressure during the operation of the bearing, according to the invention an axially displaceable bearing is provided between the bearing (200) and the threaded ring (110) With pressure ring (140). Furthermore, in the threaded ring (110), a plurality of threaded fasteners (115) can be screwed into the axially threaded holes to compress the pressure ring (140) in the axial direction. Finally, the ring nut (130) can be screwed or adjusted relative to the pressure ring (140).

Description

technical field [0001] The invention relates to a bearing locking device for bearings on the roll necks of rolling rolls, especially for rolling metal rolling materials. By means of such bearings, the rolls are mounted rotatably in the rolling stand. Furthermore, the invention relates to a method of operating the bearing locking device, on the one hand to the fitting of the bearing on the roll neck and on the other hand to the removal of the bearing from the roll neck. Background technique [0002] In principle, bearing locking devices are known from the prior art. A known bearing locking device is shown, for example, in FIG. 19 . It is known in the art as "QC-Quick Change" (Bearing Locking Device). This known bearing locking device 100 serves to fasten at least one bearing 200 on a roll neck 310 of a roll, wherein the bearing 200 is designed for mounting the roll in a rolling stand. The bearing locking device 100 has a threaded ring 110 which can be pushed onto a roll s...
