Numberless mechanical applications require articulated roller chains for the motion transmission. As known, the articulated roller chains consist of couplings among internal and external links and the only possible movement is the reciprocal rotations among the turning couples in the plane of the chain. An articulated joint has been set up that makes also possible folding of articulated roller chains in planes different from the operative ones. Practically, this articulated joint is given by the replacement of two stretches of consecutive links, positioned symmetrically on opposite sides, with chains formed by closed rings. Therefore, the continuity on each stretch is given by the connection of the ends of two ordinary chains to the loose links of the articulated chain. The articulated joint has been patented in Italy. We have mounted an articulated roller chain fitted with the set up articulated joint inside a labour-aid machine for harvesting of tobacco leaves,in which the aforesaid device makes it possible the reduction of the size of the machine itself during the road transfers.

Abstract

Numberless mechanical applications require articulated roller chains for the motion transmission. As known, the articulated roller chains consist of couplings among internal and external links and the only possible movement is the reciprocal rotations among the turning couples in the plane of the chain. An articulated joint has been set up that makes also possible folding of articulated roller chains in planes different from the operative ones. Practically, this articulated joint is given by the replacement of two stretches of consecutive links, positioned symmetrically on opposite sides, with chains formed by closed rings. Therefore, the continuity on each stretch is given by the connection of the ends of two ordinary chains to the loose links of the articulated chain. The articulated joint has been patented in Italy. We have mounted an articulated roller chain fitted with the set up articulated joint inside a labour-aid machine for harvesting of tobacco leaves,in which the aforesaid device makes it possible the reduction of the size of the machine itself during the road transfers. We have tested the performance of this machine during tobacco leave harvesting in an Italian farm cultivating Virginia Bright tobacco.
