Embodiment Construction

[0031] figure 1 A device 1 for sealing the bearing of the roll neck 2 on the barrel side is shown. On the roll neck 2 of the roll 4 there is a roll neck bushing 3 . Here, a rolling ring 5 is screwed to the roll neck bushing 3 . However, the raceway 5 is also connected to the roller 4 . The roller 4 is supported in a fitting 6 equipped with a bearing bush 7 .

[0032] On the fitting 6 a sealing element 8 is detachably connected by means of a screw 9 . An annular seal 10 , which is also a component of the sealing element 8 , prevents oil flowing between the bearing bush 7 and the roll neck bush 3 from reaching the roller 4 through the gap between the sealing element 8 and the mounting part 6 . The sealing element 8 is composed of a fastening body 11, a projection 12 and at the end of the projection 12 two radial lips 13, 13' extending further from one another. Said radial lips 13, 13' bear against a sealing surface 14 of the raceway 5.

[0033]The sealing element 8 has a s...

Abstract

The invention relates to a device (1) for sealing the ball side of a bearing of a roller journal (2), comprising a journal bushing (3) which is drawn to the roller journal (2), said journal bushing being associated with a bearing ring (5), a bearing bushing (7) which is mounted in an insertion piece (6), also comprising radial shaft seals which are associated with the insertion piece via a holder (11) and which are provided with radial lips (13, 13) which co-operate with the bearing ring (5) and a sealing arrangement (16) which is arranged upstream from the radial shaft seals so that the roller (4) can roll. The aim of the invention is to improve said device in such a way that it can be produced and operated economically such that it consists of only a small number of parts and has an improved sealing effect. According to the invention, the holder (11), the radial lips (13, 13), and a sealing lip (15, 15') of the sealing arrangement (16) form one unit which is sealingly connected in a detachable manner to the insertion piece (6).

Description

technical field [0001] The invention relates to a device for sealing the bearing of a roll neck on the roll body side, with a roll neck bushing screwed on the roll neck and equipped with a rolling ring, a bearing bushing supported in a fitting and a A sealing arrangement in which the ballen roller is arranged upstream of the radial shaft seal, wherein the radial shaft seal, which is assigned to the mounting part via a stationary body, has a radial lip interacting with the raceway. Background technique [0002] For sealing the bearings of the roll necks of rolling mill rolls, basically two different concepts are known. Wherein the first idea uses the roll neck shaft seal which rotates together with the roll, the seal lip of which presses against the corresponding friction surface with different strength due to centrifugal force at different speeds. This simultaneously leads to increased heat generation, which has a negative effect on the rubber material of the roll neck seal...
