Abstract: One embodiment of the seal housing for a face seal described herein include a base with a seal element support and a shroud both extending from the base in a common direction. The seal element support and the base define a space for receiving a seal element. The shroud includes a tip having a head portion that tapers toward a neck portion that is reduced in size relative to the head portion. The tip is secured to a stem of the shroud through a set of circumferentially distributed countersunk holes.
Abstract translation: 本文所述的用于表面密封件的密封壳体的一个实施例包括具有密封元件支撑件的底座和从基座沿共同方向延伸的护罩。 密封元件支撑件和基座限定用于接收密封元件的空间。 护罩包括具有头部部分的尖端，头部部分相对于头部部分尺寸减小，颈部朝向颈部逐渐变细。 尖端通过一组周向分布的埋头孔固定到护罩的杆上。
