Abstract

A chip or debris trap or collector retains chips, fragments and other debris generated when a serrated or splined, press fit connection is assembled between a shaft and another component such as a housing, gear, pulley or bearing. The chip collector includes a circumferential channel or groove disposed about the shaft adjacent the ring of serrations or male splines and an adjacent circumferential flange. An optional second channel or groove resides in the other component. As the shaft and the component are assembled, chips, fragments or other debris generated by the interference fit and axial sliding assembly of the components are collected in the channel or channels and retained there as the shaft fully seats within the other component.
