  • Viscous Fan Drive for an Engine Cooling System
    Publication number: 20130000998
    Abstract: A viscous fan drive for an engine cooling system has an output coupling defining a fluid operating chamber, an input coupling disposed in the fluid operating chamber, and a driveshaft coupled to the input coupling and defining a driveshaft axis. A main bearing has an inner race coupled to the driveshaft and an outer race coupled to the output coupling, the main bearing defining a bearing axis, wherein the bearing axis is normally substantially coincident with the driveshaft axis. A brace is disposed between the outer race of the main bearing and the output coupling. The engine cooling system may be provided on a machine having a rotatable frame that promotes precession of the output coupling, wherein the brace prevents movement of the main bearing along the driveshaft in response to the output coupling precession.
