device for the orientation and attitude of the position of an object, in particular a transmitting / receiving antenna for electromagnetic wellern, in at least one of three directions in space

摘要

Device for orientation and adjustment of the position along at least one space direction of the position of a part of the type comprising a support (1) for at least one structure (2, 4) including positioning and orientation means associated by appropriate kinematics to driving means. The device is comprised of drive members (5a, 5b, 5c, 5d, 6a, 6b, 6c, 6d, 8a, 8b, 8c, 8d, 9a, 9b, 9c, 9d, 30a, 30b, 30c, 30d, 37, 40a, 40b, 46) which are arranged to drive positioning and orientation means (3, 11a, 11b, 12a, 12b, 31a, 31b, 32a, 32b, 35, 42a, 42b, 44, 60, 61) which are conveniently self-contained and in that it is comprised on the one hand of means to coordinate the operation of the drive members (5a, 5b, 5c, 5d, 6a, 6b, 6c, 6d, 8a, 8b, 8c, 8d, 9a, 9b, 9c, 9d, 30a, 30b, 30c, 30d, 37, 40a, 40b, 46) and, on the other hand, of means to compensate for the mechanical clearance existing between the drive members (5a, 5b, 5c, 5d, 6a, 6b, 6c, 6d, 8a, 8b, 8c, 8d, 9a, 9b, 9c, 9b, 30a, 30b, 37, 40a, 40b, 46) and the drive means (7a, 7b, 7s, 7d, 10a, 10s, 10c, 10d, 33a, 33b, 36, 41a, 41b, 45) in mesh.
