摘要： A labyrinth seal includes a seal case with an inner-diameter leg encircling a rotation axis, and an insert fixed in the seal case and encircling the rotation axis. The labyrinth seal also includes a slinger encircling the rotation axis and wrapping around the inner-diameter leg to cooperate with the seal case to form a first part of a labyrinth path. The slinger rotates relative to the seal case. The labyrinth seal also includes a rotor that encircles the rotation axis, cooperates with the insert to form a second part of the labyrinth path, and interlocks with the insert to limit axial movement of the rotor when the rotor rotates relative to the insert. The labyrinth seal may be combined with a bearing cone, a bearing cup, and a plurality of rollers to form a roller bearing assembly.

摘要： A sealing device for sealing a gap between inner and outer members includes a mounted part attached to a cylindrical end of the outer member; at least one lip disposed radial inside the mounted part and extending toward the inner member; an annular part covering an end surface of the end of the outer member; and an annular flange formed from an elastic material connected to the annular part and disposed radial outside the end of the outer member. The inner member includes an inner portion disposed radial inside the outer member; a flange extending radially outward from the inner portion; and a through-hole formed in the flange for inserting a screw for securing the inner member to another member. The outer edge of the flange of the sealing device is disposed radial outside a portion of the through-hole that is the closest to the central axis.

摘要： Systems and methods for bearing housings are disclosed. A labyrinth seal bearing housing includes: a first seal element that is structured and arranged to be connected to a wall of a mixing vessel; a second seal element that is structured and arranged to be connected to a rotatable shaft; and a bearing support that is structured and arranged to be connected to the first seal element. The second seal element is configured to rotate relative to the first seal element and the bearing support. The first seal element and the second seal element are structured and arranged to create a tortuous flow path between an exterior and an interior of the mixing vessel.

摘要： The present invention addresses the problem of providing: a seal member in which lip wear is suppressed and resistance to muddy water is increased; and a bearing device for a wheel, provided with the seal member. An encoder (63) and an elastic member (65) form a labyrinth section (8) between an outer peripheral surface (61a) of a turned-back section (613) and an inner peripheral surface (64a) of an inner fitting section (641). The labyrinth section (8) extends axially outward and radially outward, and an inner peripheral surface (63c) of the encoder (63) that covers an inner peripheral surface (61c) of the turned-back section (613) is sloped axially inward and radially outward.
