Gyroscopic system to measure the inclination of the plane of the axes of the primary and secondary frames with respect to the axis of the top

摘要

According to the invention, the gyroscopic system is noteworthy in that: .at least in the vicinity of the plane defined by the axes (Y-Y' and X-X') of the primary (3) and secondary (4) frames, the top (2) is spherical (at 2A); .the spherical portion (2A) of the top (2) carries at least one set (22) of parallel lines (21), of different length, parallel to the axis of rotation (Z-Z') of the top (2); .an opto-electronic detector (13), integral with the casing (1), counts the number of lines (21) during the rotation of the top (2). This detector advantageously observes the top (2) through a bearing (4C) for articulation of the secondary frame (4) to the said casing (1). IMAGE
