Problems solved by technology

The dismantling unit is thus designed to be very long, so that a corresponding space must be reserved for the dismantling unit, so ultimately more space is required for dismantling the journal bushing together with the bearing assembly

Embodiment Construction

[0019] figure 1 A roller 1 is shown which has a roller journal 2 . A roller journal end 3 is arranged on the roller journal 2 . A journal bushing 4 is fitted onto the roller journal 2 , which journal bushing 4 is surrounded by a bearing sleeve 5 . The bearing sleeve 5 is held by a fitting 6 . Arranged opposite the end face 7 of the roller journal 2 is a pressure locking ring 8 , which is supported axially displaceably on the roller journal end 4 in a sealing manner via a sealing device 14 . The pressure lock ring 8 is connected with the journal sleeve 4 . A sealing element 15 is also arranged between the pressure locking ring 8 and the journal bush 4 . The pressure locking ring 8 has a feather key 9 which prevents a relative rotation between the roller journal 2 and the pressure locking ring 8 . Furthermore, an axial bearing 10 is shown, which is supported on the roller journal end 3 and connected to the mounting part 6 .

Abstract

A device for extracting the journal bush (4), the bearing bush (5) and the chock (6) from the conically designed region of the roll journal (2) of a roll (1), wherein a pressure shoulder ring (8) is arranged on a roll journal extension (3) of the roll (1), said pressure shoulder ring (8) being supported on the end face of the journal bush (4), is to be improved in such a way that it is of very small construction and the extracting movement is achieved just with small pressures of a pressure agent. To this end, it is proposed that a gap (11) be provided between the pressure shoulder ring (8) and the end face (7) of the roll journal (2), that the pressure shoulder ring (8) be coupled to the journal bush (4), and that at least one pressure agent for extracting the journal bush (4) and the chock (6) be provided in the gap (11).

Description

technical field [0001] The invention relates to a device for removing journal bushings, bearing bushings and fittings from the conically shaped region of the roll journal of a roll, wherein a pressure lock ring is arranged on the roll journal end of the roll , the pressure lock ring is supported on the end face of the journal bushing. Background technique [0002] DE 10335527 A1 discloses a device for detaching a bearing unit consisting of a fitting and a roll journal bearing arranged in the fitting from a roll journal of a support roll of a rolling stand. Here the detachment device is connected to the carrier unit. The bearing unit is removed axially relative to the roller by applying pressure between the roller journal and the bearing unit. During dismounting, the bearing unit is supported on the collar of the bearing sleeve, which is carried along with it by the bearing unit. According to another method, the bearing sleeve acts on the collar of the journal bush and det...
