Peripheral sealing arrangement

摘要

A sealing arrangement comprising a one-piece, peripheral, elastomeric sealing material for sealing a sealing space, the material containing a bearing-side sealing region and inserted between at least one outer rotatable bearing component and, mutually rotatable about the same center axis, at least one inner rotatable bearing component of a rotary joint, wherein the sealing arrangement is form-lockingly and force-lockingly connected in a detachable and replaceable manner to a structure, namely (I) to a plunge cut in a surface parallel to a horizontal outer surface of one of the inner and outer rotatable bearing components, and (II) to a projecting material protrusion with a bottom surface which is disposed on the bearing side of this material protrusion, as an integral part of the inner or outer rotatable bearing component.

1. A sealing arrangement comprising a one-piece, peripheral, elastomeric sealing material for sealing a sealing space, the material containing a bearing-side sealing region and inserted between at least one outer rotatable bearing component and, mutually rotatable about the same center axis, at least one inner rotatable bearing component of a rotary joint, wherein the sealing arrangement is form-lockingly and force-lockingly connected in a detachable and replaceable manner to a structure, namely (I) to a plunge cut in a surface parallel to a horizontal outer surface of one of the inner and outer rotatable bearing components, and (II) to a projecting material protrusion with a bottom surface which is disposed on the bearing side of this material protrusion, as an integral part of the inner or outer rotatable bearing component, the sealing arrangement comprising the following elements:
a top edge of the sealing arrangement; two upper sealing lips; an upper deformation space as a recess in the sealing arrangement; a bearing side sealing region; a barb shaped fixing portion for inserting the sealing arrangement into the bearing component; a region of the sealing arrangement that contacts the bottom surface on the bearing side of the projecting material protrusion; a lower deformation space as a recess in the sealing arrangement; wherein a) the top edge of the sealing arrangement is approximately flush with the horizontal outer surface of the rotatable bearing component in which the material protrusion of the sealing arrangement is present; and wherein b) all contact points or contact surfaces of the two upper sealing lips are either above the horizontal outer surface of the first rotatable bearing component, or all contact points or contact surfaces of the two upper sealing lips are below the horizontal outer surface of said first rotatable bearing component.
