Abstract: This invention refers to a speed reducer made up of a chain carrying nuts and of a screw, i.e., a ball screw in the first embodiment, a roller screw in the second embodiment. The ball screw or the roller screw drives the nuts on one of the straight stretches of the chain. The ball screw, or the roller screw, can be almost as long as the distance between the centers of the output sprockets on which the chain is mounted. Given these features and because the nuts wrap the ball screw, or the roller screw in a great surface, the load capacity is high. Given that in both embodiments there is rolling contact, friction is low and, as a consequence, efficiency is high, and this allows the present invention to serve also as an amplifier.

Abstract: This invention refers to a speed reducer made up of a chain carrying nuts and of a screw, i.e., a ball screw in the case of the first embodiment, a roller screw in the second embodiment. The ball screw or the roller screw drives the nuts when these are aligned on one of the straight stretches of the chain. The ball screw, or the roller screw, can be almost as long as the distance between the centers of the output sprockets on which the chain is mounted; given these features and because the nuts wrap the ball screw, or the roller screw in a great surface, the load capacity is high. Given that in both embodiments the contact is rolling, friction is therefore low and as a consequence, efficiency is high, so high indeed that it allows this invention also to serve as an amplifier.
