Abstract
A lubrication system is adapted for continuously lubricating a loose spline connection wherein a collar connects to a pair of shafts and axially spaced bearings rotatably mounting the collar and shafts in a closed housing. The collar is spline connected to the shafts and includes a lubricant chamber intermediate the spaced shaft ends fed by an axial lubricant passage across a control orifice in one of the shafts. Rotation of the shafts and collar causes lubricant entering the chamber to be centrifugally discharged through a standpipe extending part way into the chamber from a collar wall and thereby flow to the bearings.
