    • A pair of pivoting parts (10,56) are held together with a pin (16), with a first part (10), such as a rod end of a hydraulic actuator, positioned between two flanges (12) of a bracket (11) on a second part (56), with the flanges (12) having surfaces (12A) mating with sides surfaces of the rod end (10). A seal (22) is placed in each of a pair of recesses (36) on the opposite side surfaces of the rod end (10) to provide an annular seal around the surface of the pin (16) as the parts (10, 56) pivot, and also having a flange (32) forming a side seal that seats on one of the mating surfaces (12A) of the bracket (11) at a location spaced outwardly from the pin (16) and extending annularly around the pin (16). The seal portion (26) engaging the pin (16) is spaced inwardly from the respective side surface (12A) of the bracket (11), and the outer annular lip (32) seals a space (43) surrounding the pin to form a pocket (43) to receive grease that is used to lubricate the pin (16) relative to the rod end (10).
    • 一对枢转部件(10,56)与销(16)保持在一起,其中第一部件(10)例如液压致动器的杆端定位在支架(11)的两个凸缘(12)之间 )在第二部分(56)上,凸缘(12)具有与杆端(10)的侧表面配合的表面(12A)。 密封件(22)被放置在杆端(10)的相对侧表面上的一对凹部(36)中的每一个中,以便作为部件(10,56)提供围绕销(16)的表面的环形密封 )枢轴,并且还具有形成侧密封件的凸缘(32),所述侧密封件在与所述销(16)向外间隔开的位置处位于所述托架(11)的一个配合表面(12A)上并围绕所述销( 16)。 接合销(16)的密封部分(26)从支架(11)的相应侧表面(12A)向内间隔开,并且外环形唇缘(32)密封围绕销的空间(43),以形成 袋(43)以接收用于相对于杆端(10)润滑销(16)的润滑脂。
