A lubricant flow suppressor positioned proximate a rotating component for receiving ejected lubricant therefrom and reducing the kinetic energy of the ejected lubricant. The suppressor includes at least two perforated walls with a lubricant flow path formed therebetween.

Lubricant flow suppressor

A sheet metal construction for a fan spider. The spider arms each carry an integral rib running centrally along the arm and each rib is flat on its upper surface to mount a fan blade. The novelty of the invention resides in canting forwardly the spider arms. Such canting reduces certain stresses in the fan, thereby reducing cost of manufacture.

Fan spider with rake angle

A flexible fan blade construction of the type wherein a decamber limiter is carried by each spider arm and bears against one side of its associated fan blade to thereby limit flexing (decamber) thereof. According to this invention, the decamber limiter terminates short of the heel of each fan blade. High stress concentrations due to contact between the heel edge of each fan blade and its associated decamber limiter are avoided by this novel construction.

Flexible bladed fan construction

A fan construction of the type having a hoop configured hub provided with fan blades. The hub has apertures adjacent the blade roots. A viscous drive carries the hub. Rotation of the fan causes a pressure differential between the two ends of each hub aperture thus forcing an airflow radially outward to assist in cooling the viscous drive.

Radiator cooling fan construction

A method of making a sheet metal fan blade having a flattened mounting pad. The blade is to be attached to a flat spider arm of a fan hub. According to the method, a fan blade blank workpiece of cylindrical stock and of any desired outline (such as rectangular, trapezoidal, etc.) is simultaneously provided with a longitudinally running rib and a flat pad portion by stamping. In this manner, the outline of the blade is not distorted by stamping the cylindrical blank to form the flat mounting pad.
