Abstract
A drive coupling arrangement for transmitting torque from a drive arrangement to a gear assembly under test has a first coupler portion attached to the gear assembly under test. The coupler has a polygonal cross-sectional configuration and a plurality of substantially planar surfaces that extend parallel to the predetermined length of axis, in the form of an assembly nut of the gear assembly under test at a rotatory terminal thereof. A second coupler portion is coupled to the drive arrangement and has an internal cross-sectional configuration that accommodates the polygonal cross-sectional configuration of the first coupler portion. The second coupler portion has a plurality of engagement portions that communicate exclusively with a predetermined number of the substantially planar surfaces of the first coupler portion, and is axially translatable along the first coupler portion. Axial loading is absorbed by an elastomeric insert that limits the extent of the engagement between first and second coupler portions. The first and second coupler portions exert a torque against one another via the substantially planar surfaces and the engagement portions, over a predetermined range that i…
