Chain for chain transmission

Claim 2

A plate-link chain for a chain transmission comprising a plurality of plates interconnected by means of rollers, each plate comprising a substantially circular ring with the rings of different plates being substantially coplanar and disposed so as to overlap, said rollers being disposed to pass through overlapping rings.

Claim 3

A chain comprising ring links interconnected through rollers in which said rings are made with an internal diameter equal to a sum of the pitch of disposition of said rollers and the diameter of the portion of each of these rollers contacting said rings.

Claim 4

A chain comprising ring links interconnected through rollers in which said rings are made with an internal diameter equal to a sum of the pitch of disposition of said rollers and the diameter of the portion of each of these rollers contacting said rings.

Claim 5

A chain comprising ring links interconnected through rollers in which the portion of each of said rollers contacting said rings has a diameter which at least by a factor of 3.5 is less than the internal diameter of each of said rings.

Claim 6

A chain comprising ring links interconnected through rollers in which the portion of each of said rollers contacting said rings has a diameter which at least by a factor of 3.5 is less than the internal diameter of each of said rings.

Claim 7

A chain comprising ring links interconnected through rollers in which each of said rollers has at least a pair of portions contacting said rings, the length of each portion being equal to a double thickness of each of said rings and the external diameter of these rings being determined by the following inequality D < or = t(1 + cos (360*)/(z)), where D is an external diameter of each of said rings, t is a pitch of disposition of said rollers, z is the least number of teeth of the sprocket from those sprockets which interact with said chain.

Claim 8

A chain comprising ring links interconnected through rollers in which each of said rollers has at least a pair of portions contacting said rings, the length of each portion being equal to a double thickness of each of said rings and the external diameter of these rings being determined by the following inequality D < or = t(1 + cos (360*)/(z)), where D is an external diameter of each of said rings, t is a pitch of disposition of said rollers, z is the least number of teeth of the sprocket from those sprockets which interact with said chain.

Claim 9

A chain comprising ring links interconnected through rollers in which each third roller of said rollers has a pair of portions contacting said rings, the length of each portion being equal to a double thickness of said ring while the length of the middle portion of this roller contacting the sprocket tooth being equal to the thickness of this tooth, in which case at one side of this roller there is located another roller with a middle portion of the same thickness as that of said roller but having portions contacting said rings, each of these portions having a length equal to a triple thickness of said ring, and at the other side of the first of said rollers there is located a roller whose middle portion has a length exceeding the length of the adjacent rollers by a double thickness of said ring, while the length of each portion contacting said rings is equal to a double thickness of said ring.

Claim 10

A chain comprising ring links interconnected through rollers in which each third roller of said rollers has a pair of portions contacting said rings, the length of each portion being equal to a double thickness of said ring while the length of the middle portion of this roller contacting the sprocket tooth being equal to the thickness of this tooth, in which case at one side of this roller there is located another roller with a middle portion of the same thickness as that of said roller but having portions contacting said rings, each of these portions having a length equal to a triple thickness of said ring, and at the other side of the first of said rollers there is located a roller whose middle portion has a length exceeding the length of the adjacent rollers by a double thickness of said ring, while the length of each portion contacting said rings is equal to a double thickness of said ring.

Claim 11

A chain as claimed in claim 5 in which the external diameter of each said ring does not exceed the difference between the triple pitch of disposition of said rollers and the diameter of the roller portion contacting said rings.

Claim 12

A chain comprising ring links interconNected through rollers in which the diameters of the portions of said rollers contacting the sprocket teeth and the diameters of the portions of these rollers holding said rings on said rollers are made in accordance with the following inequality e > or = d + 2t (1 - cos (360*)/(z)), where e are diameters of the portion of the roller contacting the teeth of said sprocket and of said portion holding said rings on this roller, d is a diameter of the portion of said roller contacting said rings, t is a pitch of disposition of said rollers, z is the least number of the teeth of the sprocket from those sprockets which interact with said chain.

Claim 13

A chain comprising ring links interconNected through rollers in which the diameters of the portions of said rollers contacting the sprocket teeth and the diameters of the portions of these rollers holding said rings on said rollers are made in accordance with the following inequality e > or = d + 2t (1 - cos (360*)/(z)), where e are diameters of the portion of the roller contacting the teeth of said sprocket and of said portion holding said rings on this roller, d is a diameter of the portion of said roller contacting said rings, t is a pitch of disposition of said rollers, z is the least number of the teeth of the sprocket from those sprockets which interact with said chain.

Claim 14

A chain comprising ring links interconnected through rollers in which provided on the periphery of each said ring is a flat spaced from the centre of this ring at a distance determined by the following equation: r t (1.5 + 0.5 cos (360*)/(z)) -(d)/(4), where r is a distance to be found, t is a pitch of disposition of said rollers, z is the least number of teeth of the sprocket from those sprockets which interact with said chain, d is a diameter of the portion of said roller contacting said rings.

Claim 15

A chain comprising ring links interconnected through rollers in which provided on the periphery of each said ring is a flat spaced from the centre of this ring at a distance determined by the following equation: r t (1.5 + 0.5 cos (360*)/(z)) -(d)/(4), where r is a distance to be found, t is a pitch of disposition of said rollers, z is the least number of teeth of the sprocket from those sprockets which interact with said chain, d is a diameter of the portion of said roller contacting said rings.
