FIELD: mechanics.
SUBSTANCE: guide-retaining device is designed to aim fixed object towards one of celestial sphere points with the possibility to rotate specified object around horizontal and vertical axis. Besides rotary mechanisms (parts A and B) that provide for above-mentioned motions of fixed object are arranged either in double-arm or single-arm version. Moreover, each arm consists of two pairs of identical symmetrically arranged (in mirror reflection) groups of functional elements. Besides arm of mechanism for fixed object rotation around horizontal axis (part A) comprises hollow balancing disk with sliding weight inside (either liquid or segment of hard material), which under own weight permanently (even in process of rotation) occupies lower part of this disk (position of stable balance). Moreover, the latter is coaxially fixed to horizontal axis, fixed on peripheral end to cylindrical gear, besides the latter forms a functional pair with another similar gear, which is in its turn engaged to other horizontal axis. Besides the latter is coaxially fixed to the second counter-inertial disk, which is similar to the first one and also comprises similar sliding weight. Besides specified horizontal axes are held in through holes of three support stands that provide for rotation of these axes. Besides these stands are continuation of common bed plate, which in its lower part comprises vertical stand that ends with conical gear, and inside specified stand there is a cylindrical recess arranged. Besides using this recess, the whole rotary mechanism A is put onto axis-pin of central vertical stand of rotary mechanism B, which provides for rotation of part A of device together with fixed object around vertical axis. Moreover, specified vertical stand with axis-pin of mechanism B is extension of this mechanism stand, which is fixed to surface of support site.
EFFECT: simplification of design.
