Abstract:
A drive coupling arrangement for transmitting substantially exclusively torque from a drive arrangement to a gear assembly under test, the drive coupling arrangement comprising:a first coupler portion attached to the gear assembly under test, said coupler having a polygonal cross-sectional configuration that extends continuously over a predetermined length of axis, the polygonal cross-sectional configuration having a plurality of substantially planar surfaces that extend parallel to the predetermined length of axis; anda second coupler portion having an internal cross-sectional configuration that accommodates the polygonal cross-sectional configuration of said first coupler portion, said second coupler portion having a plurality of engagement portions, each of which communicating exclusively with respectively associated ones of a predetermined number of the substantially planar surfaces of said first coupler portion, and being axially translatable along said first coupler portion for a portion of the predetermined length of axis, wherein said first and second coupler portions exert a non-slip torque against one another via the substantially planar surfaces of said first coupler portion and the engagement portions of said second coupler portion, over a predetermined range of the portion of the predetermined length of axis.
