PLANETARY GEAR OF POSITIONING POLARIMETRIC OPTICS Russian patent published in 2017 - IPC F16H3/44 

FIELD: physics.

SUBSTANCE: planetary gear of positioning polarimetric optics has a disc with holes formed therein, equidistant from each other and from the disc center, in which the light filters are. A central gear is fixedly mounted on the body of the drive motor, and a disc with four satellite gears, evenly spaced around the circumference and running in the central gear, is mounted on the drive shaft of the drive motor. The gear ratio of the gear pair is 1:1.125.

EFFECT: simplification of the planetary gear for positioning the polarimetric optics in the particular case of application, when a problem arises in the astronomical practice not only in the change of the phase shifting plates themselves, but also in turning any one of them to the particular predetermined angle.
