Abstract
Abstract A balancer has a casing rotatable with a wheel such as a grinding wheel and an intermediate body housed in the casing, the casing and the body having inner gears which engage flexible gears adopted to be deformed by wave generators, whereby producing a relative rotation between the inner gears and regulating an eccentric mass of the rotating wheel so as to prevent the vibration caused by said eccentric mass.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
113 words
A balancer for regulating an eccentric mass of a machine to be rotated comprising a cylindrical casing having a device adapted to be fixed to the machine, a first inner gear secured to said casing, an intermediate member housed in said casing, a second inner gear secured to said intermediate member, a weight associated with said intermediate member, and first means for producing a relative rotation between said first and second inner gears comprising a flexible gear engaging said first and second inner gears, a wave generator in elliptical form for deflecting said flexible gear, and a shaft keyed to said wave generator, to cause movement of said weight relative to said casing.
Claim 2
Dependent Claim
113 words
A balancer for regulating an eccentric mass of a machine to be rotated comprising a cylindrical casing having a device adapted to be fixed to the machine, a first inner gear secured to said casing, an intermediate member housed in said casing, a second inner gear secured to said intermediate member, a weight associated with said intermediate member, and first means for producing a relative rotation between said first and second inner gears comprising a flexible gear engaging said first and second inner gears, a wave generator in elliptical form for deflecting said flexible gear, and a shaft keyed to said wave generator, to cause movement of said weight relative to said casing.
Claim 3
Dependent Claim
131 words
A balancer for regulating an eccentric mass of a machine to be rotated comprising a cylindrical casing having a device adapted to be fixed to the machine, a first inner gear secured to said casing, an intermediate member housed in said casing, a second inner gear secured to said intermediate member, a weight associated with said intermediate member, first means for producing a relative rotation between said first and second inner gears to cause movement of said weight relative to said casing, and second means arranged in parallel with said first means, said first and second means comprising flexible gears, one of said flexible gears engaging said first and second gears, and there is provided third and fourth inner gears secured to said intermediate member and engaging the other flexible gear.
Claim 4
Dependent Claim
131 words
A balancer for regulating an eccentric mass of a machine to be rotated comprising a cylindrical casing having a device adapted to be fixed to the machine, a first inner gear secured to said casing, an intermediate member housed in said casing, a second inner gear secured to said intermediate member, a weight associated with said intermediate member, first means for producing a relative rotation between said first and second inner gears to cause movement of said weight relative to said casing, and second means arranged in parallel with said first means, said first and second means comprising flexible gears, one of said flexible gears engaging said first and second gears, and there is provided third and fourth inner gears secured to said intermediate member and engaging the other flexible gear.
Claim 5
Dependent Claim
38 words
A balanceR of claim 2, wherein said second means has fifth and sixth inner gears positioned between said third and fourth gears and engaging said other flexible gear, and said fifth and sixth inner gears having weights thereon.
Claim 6
Dependent Claim
