RECUPERATIVE POSITIONER OF AN OBJECT

摘要

A recuperative positioner of an object comprises an output link (6) kinematically connected to the object (1), a mechanical energy accumulator (7) connected to the output link (6), a motor (9) and a device (8) for locking the position of the output link. The positioner further comprises a differential mechanism (2) with outputs (3, 4, 5). One of the outputs (3, 4, 5) is kinematically connected to the motor (9). The output (3) is connected to the output link (6). The outputs (4, 5) are interconnected through elastic elements of the accumulator (7). The locking device (8) consists of two locking units (10, 11), each being provided with a corresponding position pick-up (12, 13). The unit (10) is connected to the output (4) and the locking unit (11) is connected to the output (5). In the positioner, due to the regulation of the energy coming from the accumulator (7) to the mechanical oscillation system and backwards, the speed of action is increased thus ensuring the invariance in relation to the direction of movement of the object (1), and its operating capabilities are extended. Each locking unit (10, 11) may consist of a worm reducer and a disk with a protrusion or of a toothed disk and a double-arm lever.
