摘要
Mechanisms, having common properties, whose components lying between an input shaft 1 and two jaws 11 and 12 inclusive, ensure the clamping and then the displacement of external elements E. According to the drawing, the jaws 11 and 12, in the shape of circular rings for example, drive satellite gears E, by virtue of the threadings on the shaft 1, balls 2 and nuts 4 and 5. Starting is ensured by the permanent pressure of the spring 10 adjusted by the nut 7. The exceptional torque-pressure ratio of these assemblies makes it possible to produce multiple shapes of grippers, of machines and of tools, the components of which will be articulated to the jaws 11 and 12, designed for this purpose. Same reasoning: the specific power (power per unit mass) of a friction reducer (without play) could be multiplied up to five times, in relation to the equivalent equipment with gearing. From the robot to two tonnes. IMAGE
