Abstract
A transmission system including a damper having a hysteresis package and a flange, wherein the flange includes a first set of splines, an input shaft having a second set of splines arranged about an interior of the input shaft, wherein the first set of splines form an engagement with the second set of splines for transferring torque between the input shaft and the flange, wherein grease is included between the first and second sets of splines for lubricating the engagement of the input shaft and the flange, and a grease trap mounted to the flange located between the input shaft and the hysteresis package for restricting the grease from traveling radially down the flange and into the hysteresis package.
