Title:
SYMMETRIC DEVICE FOR CONTAINING RECIPROCATING MOTION INTO ROTATIONAL MOTION
Document Type and Number:
WIPO Patent Application WO2002063184
Kind Code:
B1
Abstract:
A symetric device for converting a rectilinear reciprocating motion into a rotational motion and vice versa, comprising a planetary gear (117), two rotors (109), means (106, 116) for imposing opposite rotations on the planetary gear and on the rotors, wherein one of these rotations is twicw a large as the other; said means are embodied by stationary gearwheels (106) with internal toothing, which mesh with gearwheels (116) with external toothing, the latter having a pitch circle diameter equal to half that of the former gearwheels; the device further comprises a driving shaft (107) or power take-off, allowing (114, 115) to maintain a perfect alignment of the rotors (109, 109) during their motion, and from which the power may be drawn or transfered to the device (100). No further member of the device (100), except the driving shaft (107), has the task of transmitting or drawing the power to/from the device. This device (100) may be used in order to form an assembly of "elementary" devices (100), like an in-line engine etc.
