摘要
A torsional and translational vibrational removingdevice (34) or balancer includes the combination of at leastone annular torsional vibration damping mass (42) and aplurality of translational vibration compensating masses (50).The annular torsional vibration damping mass (42) can bepositioned within an annular groove (46) in a housing so as tobe capable of freely rotating during rotation of the balancer(34). The annular torsional vibration damping mass (42) canalso be provided with an annular groove (46) that receives thetranslational vibration compensating masses (50). Thecompensating masses (50) are free to rotate within the annulargroove (46) in the torsional vibration damping mass (42) sothat during rotation of the balancer (34), the compensatingmasses (50) move within the annular groove (46) of thedamping mass (42) to assume a position which reducestranslational vibration while the torsional vibration dampingmass (50) rotates to reduce torsional vibration.
