  • Mechanical speed variator with eccentric dynamic masses having a balanced structure
    Patent number: 8784255
    Abstract: A mechanical speed variator is provided with eccentric masses having a balanced structure. The variator includes a drive shaft, provided with a cam composed of a circular disk eccentrically mounted on the drive shaft, which drives the driven shaft in rotation with interposition of a series of eccentric masses, each of them being composed of a circular disk with eccentric circular hole in which another mass of lower dimensions is ratably housed. The larger mass is housed and rotates inside the eccentric hole of a ring coupled with bolts to a flange and counter flange, respectively mounted on the driven shaft and the drive shaft.
