Sealing assembly
It comprises a first member with a plate attached and substantially covering at least one portion of a second member (20), both members being rotatable relative to each other and defining a tortuous way, and it further comprises a brush sealing attached to the first member and resting on a siding plate in the second member such that an inner gap formed between said first and second members is sealed. A flexible member may be provided between the brush sealing and the first member for joining them in a flexible way.
Intershaft seal assembly
An intershaft seal assembly comprises an annular seal ring disposed between a pair of annular runners connected to a hollow outer rotating shaft, and a surface of a co-axial inner rotating shaft. The centrifugal force resulting from rotation of the hollow outer rotating shaft effects engagement of the annular seal ring with the surface of the co-axial inner rotating shaft. The surface may be a radially-inward-facing surface of a retaining arm connected to the co-axial inner rotating shaft.
Self-centering seal component for high speed shaft assemblies
A seal assembly component includes an annular body having a centerline, first and second axial ends spaced along the centerline, an inner circumferential surface, and an opposing outer circumferential surface. The inner surface defines a bore for receiving a shaft and is sized such that the body inner surface frictionally engages the shaft outer surface to couple the component with the shaft. At least three cavities extend axially from the body first axial end and are spaced circumferentially about the centerline. Each cavity is located adjacent to the bore so as to define a separate centering body portion between a radially innermost surface section of the cavity and an axially-extending centering surface section of the body inner circumferential surface located inwardly of the cavity. Any radial growth of each centering body portion is lesser than concurrent radial growth of remaining portions of the body during rotation of the shaft.
IN-WHEEL MOTOR FOR ELECTRIC VEHICLE AND SEALING APPARATUS FOR PROTECTING IN-WHEEL MOTOR
An in-wheel motor for an electric vehicle is provided, including a motor body (1) including a wheel hub (11) on one side, and a sealing apparatus (2) mounted to the motor body (1) on the opposite side to the wheel hub (11), in which the sealing apparatus (2) includes a first support (510) fixedly coupled to a motor shaft (14) of the motor body (1), a second support (520) fixedly coupled to the motor shaft (14) and disposed outside the first support (520), a third support (530) covering an outer surface of the first support (510) and an outer circumferential surface of the second support (520), and rotated when the motor is operated, and a fourth support (540) coupled to an outer surface of the second support (520) and rotated when the motor is operated.
SEALING DEVICE, SEALING ASSEMBLY AND APPARATUS HAVING A ROTATING SHAFT WITH THE SEALING ASSEMBLY
A sealing device, sealing assembly and an apparatus having a rotation shaft that uses the sealing assembly. The sealing assembly includes a rotating shaft seal and a sealing device. The rotating shaft seal has a ring shaped body with the rotating shaft passing through it and a sealing portion forming a dynamic sealing cooperation with the rotating shaft. The sealing device includes a ring shaped body with the rotating shaft passing through it, and includes first and second ring shaped portions spaced apart from each other in an axial direction. The first ring shaped portion defines a static sealing surface forming a static sealing cooperation with the rotating shaft, and the second ring shaped portion defines a dynamic sealing surface forming a dynamic sealing cooperation with a portion of the rotating shaft seal adjacent to the sealing portion of the rotating shaft seal.
Labyrinth seal
A labyrinth seal including a stator and a non-contacting rotor, and annular elastomeric seals. The confronting surfaces of the stator and rotor define at least one interface passage, including a radially-outermost annular interface passage between an annular, outermost, radially-extending projection of the stator and an annular rearwardly-extending distal projection of the rotor that overlaps the radially-extending projection of the stator, the radially-outermost annular interface passage tapering outwardly and rearwardly at an acute angle relative to an axial reference line. The annular elastomeric seals are stationary with the stator during dynamic operation of the rotor, and are not contacted by a surface of the rotor during dynamic operation. The interface can also have two radially-disposed exclusion chambers, the outer exclusion chamber being defined in part by a radially-inboard projection of the rotor. The stator can have a projection providing a contact avoidance interface position inboard of at least two contaminant-excluding interfaces.
SEAL ARRANGEMENT AND METHOD FOR MANUFACTURING A SEAL ARRANGEMENT
Provided is a seal arrangement for sealing an internal space between two components mounted for rotation relative to each other, in particular for sealing a wheel bearing. The seal arrangement comprises a first carrier element, which can be connected to the first component, and a second carrier element, which can be connected to the second component. A sealing element is formed on at least one of the carrier elements and rests against the respective other carrier element at least one contact point. It is provided that at least one opening is made in the first carrier element, into which a ventilation element is inserted. It is provided that a receiving space is formed on the ventilation element, which is delimited in the radial direction by a collar on a base body of the ventilation element, wherein a gas-permeable membrane or a porous body is arranged in the receiving space.
LABYRINTH SEAL
A labyrinth seal including a stator and a non-contacting rotor, and annular elastomeric seals. The confronting surfaces of the stator and rotor define at least one interface passage, including a radially-outermost annular interface passage between an annular, outermost, radially-extending projection of the stator and an annular rearwardly-extending distal projection of the rotor that overlaps the radially-extending projection of the stator, the radially-outermost annular interface passage tapering outwardly and rearwardly at an acute angle relative to an axial reference line. The annular elastomeric seals are stationary with the stator during dynamic operation of the rotor, and are not contacted by a surface of the rotor during dynamic operation. The interface can also have two radially-disposed exclusion chambers, the outer exclusion chamber being defined in part by a radially-inboard projection of the rotor. The stator can have a projection providing a contact avoidance interface position inboard of at least two contaminant-excluding interfaces.
External material intrusion-proof sealing system for rollers used in conveyor belts for bulk materials
A sealing system which is designed to leverage the centrifugal acceleration of solids and liquids due to the natural rotation of the roller, expelling them outside, preventing most of the contamination from trying to penetrate the roller seals. Excess of contaminants that is not centrifugally expelled is blocked by the following internal sealing system.
STRUT BEARING ASSEMBLY WITH METAL GUIDE RING AND SPRING SEAT
A suspension strut bearing assembly for connection between a portion of a suspension strut and a vehicle body. The bearing assembly includes an upper spring plate having an upper surface, a lower surface, and an opening defined therethrough, accommodates the piston rod of the shock absorber. The upper surface includes a first, concave race configured to receive rolling elements, and the lower surface includes a spring seat that is adapted to receive a suspension spring. An upper bearing washer that includes a second race that faces the first concave race 26 is provided. Rolling elements are located between the first, concave race and the second race. A retainer retains the upper bearing washer to the spring plate. The assembly eliminates the need for a separate lower bearing washer.
