Embodiment Construction

[0031] figure 1 A chock 1 is shown in which a roll journal 27 (not shown) is supported via a journal bushing 24 and bearing bushing 28 (not shown). Bearing sleeve 24 links to each other with roll journal 27 anti-rotationally, and bearing sleeve 28 is then fixed in bearing housing 1 li. Between the bearing housing 28 and the journal housing 24 is a continuous lubricant film. The lubricant 2 enters the gap between the bearing sleeve 28 and the journal sleeve 24 via a lubricant circulation system via the lubricant inflow groove. When the load is distributed symmetrically, each half of the lubricant 2 flows out on the barrel side 3 and the outflow side 4 . Circumferential lubricant receiving grooves 5 , 6 are machined into the bearing housing 1 on the barrel side 3 and the outflow side 4 for the discharge of the lubricant 2 . These lubricant receiving grooves 5 , 6 expand in the lower area into two lubricant receiving chambers 7 , 8 which are located below the lowest point 9 o...

Abstract

In an installation part (1) in a rolling stand for receiving a roll journal (24) having a journal bush (24) of a roll which is used in the processing of steel and non-ferrous metals, wherein the installation part (1) has a cambered side (3) which faces the roll and a run-out side (4) which lies opposite the cambered side (3), having lubricant receiving spaces (7, 15, 16) on the cambered side (3),at least one housing tongue (23) is provided on the cambered side (3) for the at least partial delimitation of the lubricant receiving spaces (7, 15, 16) with respect to one another and for the formation of a gap (25) with the journal bush (24), the width of which gap (25) is below a predefined gap width threshold value.

Description

technical field [0001] The invention relates to a chock in a rolling mill stand for receiving a roll neck, with a journal sleeve for a roll used in steel- and non-ferrous metal working, wherein the chock has a roll facing the roll The body side and an outflow side opposite the roll body side have lubricant receiving chambers on the roll body side. Background technique [0002] Roll bearings, especially oil-film-roll bearings, have been used in rolling mill construction for decades. Here, all load-bearing bearing components, including fastening elements and seals, are arranged in a bearing housing, the so-called bearing housing. [0003] On the journal of the roll, a journal sleeve is arranged on the journal of the roll. Together with the bearing sleeve, the journal sleeve forms a radial bearing, wherein the bearing sleeve is fixed in the bearing housing. The bearing sleeve surrounds the journal sleeve. [0004] Between the outer surface of the journal sleeve and the inne...
