Patent ID: 7998007

Claim:
A sprocket and chain assembly for transferring torsional force between at least first and second shafts comprising: a “m” number of identical chains wherein “m” equals at least two (2), each chain being fabricated from at least two types of links that differ slightly in their geometry, the different links of each chain being arranged in an identical random predetermined set pattern that repeats upon at least one revolution (T) of each chain; a “m” number of sprockets on each shaft for engagement with one of each said “m” number of chains; and wherein said chains are phased from one another on respective sprockets by T m ± 0.1 ⁢ ⁢ T m and wherein said sprockets on each shaft having L number of teeth, and said teeth are phased from one another 2 ⁢ Π L ⁢ ⁢ m radians from one another.
