Abstract:

The present invention provides apparatus for precisely distributing a liquid coolant or lubricant about the interior of a rotary machine. Distribution in known quantity is sought over a wide range of shaft speeds. In one embodiment the apparatus of the invention is employed to distribute oil in various quantities to bearings and splines within a clutch assembly. Lubricating oil is sprayed from a stationary nozzle into the interior of a rotating shaft. An insert at the interior of the shaft has a plurality of longitudinal splits which intercept and collect the oil in proximity to orifices in communication with bearings and splines to which oil distribution is desired.
