A sealing device seals a gap between a housing and a rotational shaft located in a shaft hole provided in the housing. The sealing device includes: an annular mounted part that is to be mounted on an inner peripheral surface of the shaft hole; an inner annular part located radially inside of the mounted part; a seal lip extending from the inner annular part and for being in contact with the outer peripheral surface of the rotational shaft; a bellows part connecting the mounted part with the inner annular part; a sound insulation ring fixed to the mounted part and expanding radially inward from the mounted part, the sound insulation ring including an opening through which the rotational shaft passes; and a circular annular sound insulation lip projecting from the inner annular part or the bellows part toward the sound insulation ring and including a distal end being in slidable contact with the sound insulation ring. The sound insulation ring includes a circular annular part with which the distal end of the sound insulation lip is in contact, and a protruding wall disposed radially inside of the circular annular part and radially outside of the opening, the protruding wall protruding toward the inner annular part.

The present invention relates to a stuffing box assembly comprising a stuffing box and a solid plate, the solid plate may be placed at the shaft introducing end of the stuffing box, between the stuffing box and a surface, when the stuffing box assembly is mounted on to the surface, the solid plate may be on a first side provided with a pressure plate flange and on a second side be provided with a counter pressure plate flange, wherein the pressure plate flange and/or the counter pressure plate flange is provided with one or more locking projections pointing towards the solid plate.

Systems and methods include providing an aircraft with a fuselage and a wing assembly rotatable relative to the fuselage about a stow axis between a flight position and a stowed position. The aircraft includes an engine reduction gearbox having a retractable driveshaft that selectively engages the mid-wing gearbox via axially translatable motion along a rotation axis when the wing assembly is in the flight position. The mid-wing gearbox includes a plunger seal that is displaced in response to contact with the retractable driveshaft. Displacement of the plunger seal allows lubricant to flow through an inner bore in the retractable driveshaft, across splines of the retractable driveshaft and the mid-wing gearbox, and through lubrication ports in the mid-wing gearbox to lubricate the engine reduction gearbox, splines of the retractable driveshaft and the mid-wing gearbox, and the mid-wing gearbox via a single lubrication system.

To provide a dust cover capable of maintaining a state in which a first flexible part and a second flexible part of a bellows are fitted onto a mounting member. A dust cover includes a bushing, a bellows, and a mounting member. The mounting member has a main body and a flange part.

A rotary seal assembly for a rotary kiln having a hood and a rotary drum with an opening formed between the drum and the hood, and an end. The rotary seal assembly includes a flexible framework arrangement that attaches to the end. The rotary seal assembly includes a riding surface that engages the drum as the drum rotates. The riding surface includes a series of seal segments with each seal segment having a mounting eye positioned to eliminate a fulcrum point at the mounting eye. The rotary seal assembly includes a seal that is supported by the riding surface and is in essentially 360-degree contact with the drum when it is rotating and seals the opening between the drum when it is rotating in the hood to prevent fluid flow into and out of the end. A rotary seal assembly for a rotary kiln having a hood and a rotary drum with an opening formed between the drum and the hood, and an end, includes redundant tension springs which form a complete 360-degree circle around the drum. A method for sealing an opening formed between a drum and a hood.

A cylindrical shaft seal packaging sleeve that is inserted in a shaft seal an inner peripheral surface of which slidably contacts with a rotation shaft includes an insertion end portion that is inserted in the shaft seal and a mounting end portion having a larger outer diameter than that of the insertion end portion, a chamfered portion is formed in each of the insertion end portion and the mounting end portion and a step portion having a larger outer diameter than that of the chamfered portion is provided in an axial deeper side than the chamfered portion, and a minimum diameter of the step portion in the insertion end portion is smaller than a minimum diameter of the shaft seal.

A seal is provided for insertion in a bore in an outer member and engaging an inner member received in the bore. The seal includes an outer annular insert having a first diameter and an inner annular insert having a second diameter smaller than the first diameter. An elastomeric body includes an outer portion over-molded on the outer annular insert and an inner seal over-molded on the inner annular insert and including an intermediate web extending between the outer portion and the inner portion. The web extends both axially and radially relative to a center axis of the outer annular insert. The inner seal includes an inboard sealing surface and the outer portion including an outboard sealing surface.
