Embodiment Construction

[0023] figure 1A radial deep groove ball bearing is shown in partial section. Between the outer bearing ring 16 and the inner bearing ring 17 , the rolling bodies enclosed in the rolling-element cage each rotate on raceways configured as raceways. The bearing gaps formed between the bearing rings 16 , 17 are each covered on the axial outer sides of the rolling bearing by the annularly encircling cover 1 according to the invention along a covering plane 2 , which is perpendicular to the rolling bearing axis 18 and in the radial direction Extend up. In this case, the cover part 1 has an inner side axially facing the bearing interior to be sealed and an outer side facing axially away from said inner side and the bearing interior. The cover part 1 is designed as a one-piece cover made of sheet metal. The cover has a disk-shaped base 3 extending in the radial direction in the mounted state, the disk plane of which extends parallel to the cover plane 2 . Radially outwardly from ...

Abstract

The invention relates to a sealing assembly for a rolling bearing, the sealing assembly having at least one cover element (1) for covering a bearing gap along a cover plane (2), the cover element (1), for securing purposes, having a securing section and a sealing collar as well as a base part (3) connecting the securing section and the sealing collar, and at least one sealing surface (6, 7, 9, 10) being provided on the sealing collar for non-contact sealing. According to the invention, at its starting section, the sealing collar extends from the base part (3) diagonally toward the inner side of the cover element (1) facing the bearing interior and at its end section it extends from the inside toward the outer side of the cover element (1) facing away from the bearing interior. At the same time, the sealing collar forms a sealing surface (7, 10) substantially perpendicular to the cover plane (2) and at the end of the end section at least one edge (4) impeding the inflow of impurities into the bearing interior.

Description

technical field [0001] The invention relates to a sealing arrangement for a rolling bearing having at least one cover part for covering a bearing gap along a cover plane, the cover part having a fastening section and a sealing flange for fastening and connecting the fastening section and the seal At the base of the flange, at least one sealing surface is arranged on the sealing flange for contact-free sealing. Background technique [0002] Such a sealing arrangement is known from DD 47 076, in which there is provided a cover made of sheet metal for sealing the bearing gap formed between two bearing rings of a rolling bearing. The cover plate is clamped on the outer edge on the shoulder of the bearing outer ring. A bead extending perpendicular to the plane of the disk is arranged radially on the inside of the disk part. The bead forms a contact-free seal with the inner bearing ring at the sealing gap. A disadvantage of this configuration is that the bead extends toward the...
