Coupler arrangement for isolation arrangement for system under test

Abstract

A drive coupling arrangement for transmitting torque from a drive arrangement to a gear assembly under test is provided with a first coupler portion attached to the gear assembly under test. The coupler has a polygonal cross-sectional configuration and has 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 for a portion of its length of axis. The first and second coupler portions exert a torque against one another via the substantially planar surfaces of the first coupler portion and the engagement portions of the second coupler portion, over a predetermined range of the portion of the predetermined length of axis. A resilient biasing element urges the second coupler portion axially toward the first coupler portion. The resilient biasing element urges the second coupler portion axially upward toward the first coupler portion. An isolation support supports the energy transfer system so as to be translatable in at least one plane of freedom.
