Abstract:
An arrangement for isolating a gear system while it is subjected to a test process for noise, the gear system being of the type having an energy input and at least one energy output, the arrangement comprising:a base for supporting the arrangement and the gear system; isolation support means for supporting the gear system whereby the gear system is translatable in at least one plane of freedom with respect to said base; engagement means for securing the gear system to said isolation support means, a first coupler portion attached to the gear system, 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; and a 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 that communicate exclusively with 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 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.
