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.
Claims1
A complex variator apparatus comprising:
- a single drive shaft having an axis of rotation, said axis of rotation being a main axis of rotation of the complex variator apparatus;
- a single cam integral with and revolvable jointly with said single drive shaft;
- a plurality of individual variators in which each individual variator comprising:
- at least one first mass formed of a disk having a center that does not coincide with said main axis of rotation, the first mass having an eccentric hole, said single cam housed within and freely rotatable within said eccentric hole;
- at least one second mass formed of a disk with a center that does not coincide with either of said main axis of rotation and said center of the first mass, the second mass having an eccentric hole in which the first mass is housed within and freely rotatable therein;
- a ring having a disk shape and having a center coinciding with said main axis of rotation, said ring having an eccentric hole within which the second mass is housed within and freely rotatable therein;
- a plurality of sliding bearing positioned between said cam and the first mass and between the first mass and the second mass and between the second mass and said ring, said ring having holes evenly angularly spaced, said holes having centers lying on a common circle in which the common circle has a center coincident with said main axis of rotation, said common circle being concentric with and internal to a circular crown, said circular crown having an internal circumference tangent to the hole;
- a flange and a counter flange respectively coupled to the ring of a first individual variator and a last individual variator of said plurality of individual variators by means of bolts inserted into the holes of the rings, said flange and said counter flange being respectively mounted on a driven shaft and said single drive shaft, each of said flange and said counter flange having a center coincident with said main axis of rotation, said single cam being coupled with all of the first masses, said plurality of individual variators being mounted on said single cam in a progressively staggered manner one-after-another by a common angle with a value equal to a ratio between a round angle and a number of said plurality of individual variators, the ring of each individual variator having a number of the holes equal to the number of said plurality of individual variators.
