摘要： A seal assembly (10) for sealing between a housing (20) component and a rotating shaft (66). The seal assembly comprises a pair of relatively rotating rings (34, 44) defining a seal interface. One ring (44) is stationary relative to the housing component. A flexible compressive seal element (48) is compressed axially between the housing component and an axially movable biased compression ring (46) to urge it into radial compressive sealing contact with a cylindrical surface on the stationary ring.

摘要： A seal assembly for use with a rotating shaft. The seal assembly comprises a seal ring, a seal ring shell and bellows. The seal ring defines an axially extending annular surface and a radially extending seal face. The seal ring shell has a front piece and a back piece secured together. The front piece includes a foot portion defining an axially extending engagement surface for interference-fit engagement with the annular surface of the seal ring. The front piece further includes a radially extending shin portion connected to the foot portion and located radially outward of the foot portion. The foot portion includes an inner foot portion extending axially from connection of the foot portion with the shin portion. The foot portion at its engagement surface has an axial length. The inner foot portion at its engagement surface has an axial length. The shin portion has an axial length. The bellows defines an effective diameter at zero pressure applied on the seal ring. The interface of the foot portion with the seal ring defines an interference diameter. It is preferable that the axial length of the foot portion is greater than the axial length of the shin portion. It is also preferable that the ratio of the axial length of the inner foot portion at its engagement surface to the axial length of the foot portion at its engagement surface is greater than 0.5. It is further preferable that the interference diameter is within +10 % and -10 % of the effective diameter of the bellows at zero differential pressure.
摘要翻译：与旋转轴一起使用的密封组件。密封组件包括密封环，密封环壳和波纹管。密封环限定轴向延伸的环形表面和径向延伸的密封面。密封环外壳具有固定在一起的前部件和后部件。前部件包括限定轴向延伸的接合表面的脚部，用于与密封环的环形表面干涉配合接合。前部件还包括连接到脚部并且位于脚部的径向外侧的径向延伸的胫部。脚部包括从脚部与胫部部分的连接轴向延伸的内部脚部。其接合表面的脚部具有轴向长度。其接合表面的内脚部具有轴向长度。胫部具有轴向长度。波纹管在施加在密封环上的零压力下限定有效直径。脚部与密封环的界面限定干涉直径。优选地，所述脚部的轴向长度大于所述胫部的轴向长度。内脚部的接合面的轴向长度与其接合面的脚部的轴向长度的比也优选为0.5以上。进一步优选的是，干扰直径在零差压下在波纹管的有效直径的±10％和-10％之内。
