摘要： A sealing system includes a shaft seal plate, a seal guide having a tab, and a shaft seal coupled to the seal guide. A guide slot is formed in the shaft seal plate, and the tab extends into the guide slot. The shaft seal is configured to form and substantially maintain a seal at an axle bar as the axle bar rotates and pivots. The seal guide is configured to translate relative to the shaft seal plate as the axle bar pivots, and the tab is configured to block a rotation of the seal guide and the shaft seal relative to the shaft seal plate as the axle bar rotates.

摘要： 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: a mounted part that is to be mounted on the shaft hole; an inner annular part; a seal lip that is to be 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 a circular annular sound insulation lip projecting from the inner annular part or the bellows part toward the sound insulation ring. The sound insulation lip protrudes obliquely radially outward. The sound insulation ring includes a circular annular part with which the distal end of the sound insulation lip is in contact. The circular annular part of the sound insulation ring is inclined with respect to an axial direction of the shaft hole such that the distance between an outer portion of the circular annular part and the inner annular part when projected in the axial direction of the shaft hole is greater than the distance between an inner portion of the circular annular part and the inner annular part when projected in the axial direction.

摘要： A mechanical seal assembly has rotational and stationary sealing members) and a drive unit, which is axially adjacent one of the sealing members. An energizing member urges the drive unit towards the sealing members. A retainer axially and radially retains one of the sealing members. The drive unit is in contact with one of the rotational and stationary members by way of contacting surfaces which are in the range of 1 and 20 light bands of flatness, inclusive.

摘要： An exemplary carbon seal assembly generally may include a stator fixable to a static component, such as a mechanical housing of a gas turbine engine, and a rotor fixable to a rotating component, such as a shaft of the gas turbine engine, where the rotating component is rotatable relative to the static component. The carbon seal assembly may also include a carbon ring and a spring attached thereto positioned between the stator and the rotor, where the spring may be configured to move the carbon ring fore and aft between the stator and the rotor. The carbon seal assembly may further include a diaphragm operatively attached to stator and to the carbon ring and spring combination.

摘要： Self-sealing bellows for use with vehicles are disclosed. An example bellows includes a tubular body being expandable and contractible along an axis of the body. The bellows also includes a lining disposed along a surface of the body and a liquid or gelatinous material disposed between the body and the lining. The liquid or gelatinous material hardens when exposed to a fluid.

摘要： The present invention relates to a gasket, a magnetic switch of a starter including the same, and a starter including the magnetic switch, the gasket including: a membrane which carries out a sealing function and is made of a resin material having flexibility; and a membrane washer provided along the edge of the membrane in order to prevent bending of the membrane, wherein the membrane and the membrane washer are insert injected. Unlike prior art, the present invention can enhance the durability of the membrane by insert injection molding a hard membrane washer into the membrane having flexibility, can enhance a waterproofing performance by enabling the membrane to be firmly fixed to a plunger, and can enhance an assembly performance by enabling assembly through an automatic production line.
