A production method for a cover attached to an outer ring of a hub unit including procedures as follows. A nut is supported by a first protrusion of a first mold. By a second protrusion of a second mold, a core bar including a cylindrical section to be inserted into the outer ring is supported. A resin material is injected into a cavity formed by the first mold and the second mold to form a cover including a nut and a core bar. The cover is detached from the second mold by moving the first mold in a direction of being separated from the second mold. After this, the cover is detached from the first mold by pushing out the cover in a die matching direction with a pin disposed in the first mold.

Systems and apparatus for an oval O-ring groove for aircraft wheels may generally comprise an inboard wheel portion and an inboard O-ring groove. The inboard wheel portion may include an inboard rim located opposite of an inboard tubewell. The inboard tubewell may have an inboard mating surface located on an axially outward edge of the inboard tubewell. The inboard O-ring groove may be formed as a partial oval-shaped recess located on an outer edge of the inboard mating surface.

A two-piece seal assembly includes first and second seal subassemblies, each shaped as a semicircular ring. The first seal subassembly has a first stator subassembly and a first rotor subassembly that cooperate to form a first semicircular segment of a labyrinth. The second seal subassembly has a second stator subassembly and a second rotor subassembly that cooperate to form a second semicircular segment of the labyrinth. The first and second stator subassemblies, when affixed to each other, form a ring-shaped stator that encircles a rotation axis. The first and second rotor subassemblies, when affixed to each other, form a ring-shaped rotor that encircles the rotation axis and can rotate about the rotation axis relative to the stator. When the first and second seal subassemblies are affixed to each other, the first and second semicircular segments meet such that the labyrinth encircles the rotation axis.

Wheel bearing units are disclosed. In one example, a wheel bearing unit includes an outer ring element and an inner ring element, between which there are arranged at least two rolling body rows. The inner ring element may have a radial flange which is fastenable to an axle body or to a wheel. The radial flange and/or the inner ring element may have at least one projection on a surface facing toward the outer ring element.

The present invention is intended to provide a protective cover, comprising an inner ring 12 with an inner ring track surface 12A on an outer peripheral surface; an outer ring 13 with an outer ring track surface 13A on an inner peripheral surface; a bearing with rolling elements 14 between the inner ring track surface 12A and the outer ring track surface 13A; a magnetic encoder 8 that is positioned at one axial end portion of the bearing and fixed to the inner ring 12; and a magnetic sensor that is fixed to the outer ring 13, a cup-shaped protective cover 1 press-fitted into the outer ring 13 to cover the magnetic encoder 8 and intervene between the magnetic encoder 8 and the magnetic sensor is formed by performing cold press molding of an austenitic stainless steel plate material with a nickel content of 8.5 to 13 weight %.

A removable spindle axle improvement using a cap attached to a rim formed along an inside surface of a torsion arm, wherein the cap seals a threaded fastener. The rim used for attachment can be a groove, collar, or a collared washer. In an alternative embodiment, a first O-ring is positioned along an end of a spindle axle tapered body and a second O-ring groove is positioned along an opposite end of the spindle axle tapered body to hermetically seal an area of the spindle axle therebetween. In a further embodiment, a first O-ring is positioned along one end of a spindle axle socket and a second O-ring is positioned along a second end of the spindle axle socket to hermetically seal an area of the spindle axle therebetween.

A method of producing a wheel bearing apparatus includes: performing positioning of a slinger of a sealing device with respect to a base shaft portion of a hub spindle by pressing a jig to press-fit the slinger to the base shaft portion, using an inner ring contacted surface, which is a step portion between a small-diameter shaft portion and a large-diameter shaft portion of the hub spindle, as a reference surface; and fitting, after the slinger is press-fitted to the base shaft portion, an inner ring to the small-diameter shaft portion such that the inner ring reaches a position at which the inner ring comes into contact with the inner ring contacted surface, in a state where an outer ring, rolling elements, and the sealing device have been assembled to the hub spindle.

A sealing assembly insertable between a stationary outer ring and a rotating inner ring of a bearing or hub bearing unit, having a first C-shaped shield supported by the inner ring and a second L-shaped shield supported by the outer ring. The first shield has a first annular sealing element having a first annular lip that extends axially cantilevered from the flange portion of the second shield in a position facing a radially outer sleeve shaped portion of the first shield and a second annular lip, elastically deformable, arranged radially on the inside of the first lip and which cooperates in contact with a radially inner sleeve shaped portion of the first shield, which carries a second sealing element having a third annular lip, which extends axially cantilevered from the first shield and towards the second shield and which is radially interposed between the first and the second lip.

Wheel bearing unit with a wheel hub, wherein the wheel hub has an integrally formed wheel flange on one end thereof and an inner ring that is rotatable together with the wheel hub, wherein the inner ring is fastened on the wheel hub through the use of a rolling rivet connection in order to pre-tension a row of rolling elements in relation to an outer ring, and with an encoder provided on the inner ring and extending radially towards the outer ring, and with a protective cover fixed on the outer ring in order to close and seal annular openings formed between the outer ring and the wheel hub, and wherein a cylindrical section of the protective cover is pressed in and wherein a bottom section extends inwardly from the cylindrical section in a radial direction in order to cover an inner-side end of the wheel hub, wherein the cylindrical section is joined with a substance bond to the outer ring and wherein the substance-bond connection is produced through the use of a hardening fluid and wherein the fluid is held in a filling reservoir provided between the cylindrical section and the outer ring.

This invention is a rim shield for covering an automobile rim and providing a seal between a flange of the automobile rim and a sidewall of the tire around the rim. The rim shield has a circular shaped body with a handle positioned on the side of the body and a channel formed along a periphery of the body on its bottom side, or the side that faces the rim. The channel houses an O-ring that is shaped in a manner that allows the O-ring to seal the space between the sidewall and the flange. Once in this position, the rim shield can be rotated using the handle in a secure seal between the O-ring and space defined by the sidewall and flange.
