摘要： A mechanical end face seal assembly with first and second, relatively rigid, primary seal rings of a generally T-shaped cross-section and a pair of annular secondary elastomeric seal rings. The secondary rings provide a combination of radial compressive load and axial end face load and are of generally parallelogram shaped cross-section. One secondary seal member extends radially outwardly from its associated primary seal ring and the other secondary ring extends radially inwardly from its associated primary ring.

摘要： A seal and sealed mechanism adapted to prevent dirt from entering portions of the seal cavity. The seal includes at least one annular primary seal ring of generally L-shaped cross-section and having a sealing surface formed on one side of the radial flange of the primary ring. An elastomeric secondary seal ring is also provided, with such ring being generally parallelogram-shape in cross-section. The inner diameter of the secondary ring fits snuggly in use over the outer diameter of the axial flange of the primary ring. A dirt excluder lip extends outwardly from one face of the secondary seal ring and covers the end portion of the radial flange of the primary ring to prevent foreign material from entering the cavity between the outer inclined surface of the secondary ring and the end surface of the radial flange of the primary ring. The excluder lip is effective in various axial positions of the seal. The seal may comprise a pair of identical primary and secondary rings in face to face relation. The seal may be incorporated in a sealed mechanism such as a track roller, track pin, or final drive for a crawler tractor or the like.

摘要： An improved rotary end face mechanical seal assembly particularly adapted for intermittent use in severe service environments. The seal comprises at least one relatively stiff primary sealing ring having an axially facing, radially directed end face portion, at least a part of which, in use, engates an oppositely directed member to form a primary seal band area. The primary seal ring includes an at least partially outwardly directed seat for receiving a portion of a secondary sealing and driving member which is made from an elastomeric material, which engages the seat so as to form a secondary seal, to transmit driving torque to said primary seal, and to prevent relative rotation between the primary seal ring and the secondary sealing and driving member. The secondary member also transmits an axial end load to the primary seal face to achieve the primary seal. The primary seal ring contains means forming a lubricant reservoir, so that lubricant may be retained in the area of the primary sealing surface even when the apparatus containing the seals is not in use, and so that, upon starting up, the lubricant will be supplied immediately to the seal faces lying immediately adjacent the seal band area. In a preferred form, the seal assemblies are formed from substantially identical pairs of seal parts, arranged in a mirror image relation.
摘要翻译：一种改进的旋转端面机械密封组件，特别适用于在恶劣的使用环境中间歇使用。密封件包括至少一个相对刚性的主密封环，其具有轴向面向的径向指向的端面部分，其至少一部分在使用中构成相对定向的构件以形成初级密封带区域。主密封环包括至少部分向外指向的座，用于接收由弹性体材料制成的二次密封和驱动构件的一部分，该弹性材料与座接合以形成二次密封，以将驱动扭矩传递到所述主密封件密封，并且防止主密封环和次密封和驱动构件之间的相对旋转。次级部件还将轴向端部负载传递到主密封面以实现主密封。主密封环包含形成润滑剂储存器的装置，使得即使当不使用包含密封件的装置时也可以将润滑剂保持在主密封表面的区域中，并且在启动时将提供润滑剂马上到密封面紧邻密封带区域。在优选形式中，密封组件由基本相同的成对的密封部件形成，以成对的方式配置。

摘要： The present invention is directed to a grit exclusion and oil retention seal for use in extremely hostile environments. These environments include, but are not limited to sealing oil within cavities forming parts of earth drilling bits and the like. Seals such as these, include the ability to seal oil within a cavity in a reliable manner even under extreme conditions of vibration, mechanical shock, and the presence of grit, sand, water, dirt and mixtures thereof. In order to function properly in this environment, the seal must also provide a certain amount of axial end play so that relative movement of the sealed parts will not permit the seal to leak.In this connection, a heavy duty seal of the type with which the invention is concerned must provide not only a primary or relatively moveable seal, but also a secondary seal. The seal assembly must include means for transmitting torque from the housing or carrier to the primary seal rings. Means must be present for applying and maintaining an axial end face load of the proper range.
摘要翻译：本发明涉及用于极端恶劣环境中的砂粒排除和保油密封。这些环境包括但不限于形成地钻钻头的部分的腔内的密封油等。诸如这些的密封件包括即使在极端的振动，机械冲击和砂砾，水，污物及其混合物的极端条件下，也可以以可靠的方式密封腔内的油。为了在这种环境下正常工作，密封件还必须提供一定量的轴向端部，使得密封部件的相对移动不会使密封件泄漏。在这方面，与本发明有关的类型的重型密封件不仅必须提供主要或相对可移动的密封件，而且还必须提供二级密封件。密封组件必须包括用于将扭矩从壳体或载体传递到主密封环的装置。必须存在用于施加和保持适当范围的轴向端面载荷的装置。
