    • The present invention relates to a viscous shear coupling (e.g. for use as a fan drive comprising an annular driving member, usually in the form of a disc having a hub portion for mounting on a driving shaft, a driven member having an internal annular chamber receiving said annular driving member, with facial planar and circumferential surfaces of said chamber and opposing facial planar and circumferential surfaces of said driving member at least in part being in close-spaced relationship, said driven member being axially and radially located for rotation relative to said driving member, viscous coupling fluid in said chamber, and a 0.0005 to 0.0015 inch thick layer of non-metallic anti-friction material on at least those parts of said facial planar and circumferential surfaces of said annular chamber which are in close spaced relationship, thereby forming journal and thrust bearing means for the relative rotation of the driving member and the driven member.
    • 本发明涉及一种粘性剪切耦合器(例如,用作风扇驱动器,其包括环形驱动构件,通常为具有用于安装在驱动轴上的毂部的盘形式,其具有内部环形室接收的从动构件 所述环形驱动构件具有所述腔室的面部平面和圆周表面,并且所述驱动构件的相对面向平面和圆周表面至少部分地处于紧密间隔的关系中,所述从动构件被轴向和径向地定位成相对于所述驱动 在所述室中的粘结耦合流体,以及在所述环形室的所述面部平面和周向表面的至少那些部分上的0.0005至0.0015英寸厚的非金属抗摩擦材料层,其间隔间隔开,从而形成 用于驱动构件和从动构件的相对旋转的轴颈和推力轴承装置。
