Device for converting rotational movement into cyclic translational movement of part - follows closed curve having linear trajectory section perpendicular to axis of symmetry cutting rotational axis of drive wheel around which rotate primary and secondary satellite gears

摘要

The device is for converting rotational movement into a cyclic translational movement of a part (17) following a closed curve having a section with a linear trajectory. The linear trajectory section extends perpendicular to an axis of symmetry (zz') cutting through the axis of rotation of the drive wheel (1). Primary (7) and secondary (14) satellite gears rotate around the driving wheel. The axis of symmetry bisects the angle (a) formed by the radial axes (8A,8B) of satellite gears at the two ends of the linear section. The support (12) of the secondary satellite gear makes, with the axis of symmetry, an angle equal to the angle (a) in an opposite direction of inclination to the radial axes. The support rotates about its axis (11) relative to the driving wheel with an angle double that of the angle (a).
