| 摘要 |
A shaft coupling between first and second shafts, the shaft coupling including a resilient member of low torsional spring rate connecting the shafts, a pair of surface elements rotatable as a unit with respective ones of the shafts, and a plurality of elastically deformable spheres disposed in substantial compression between the surface elements and generating resistance to rolling movement so as to retard relative angular movement between the surface elements, the resistance to rolling movement torsionally damping the resilient member to eliminate looseness or sponginess between the shafts.
