FIELD: mechanical engineering. ^ SUBSTANCE: planet gearing mechanism comprises shaped gear rack (9), base (1) with guides for longitudinal movements of the rack, rotatable lever (5) with gear wheel (4), and driving gear wheel (10). Shaped rack (9) has guides with flat (7) and profiled surfaces (2) and (8). The axis of rotation of wheel (10) passes through shaped rack (9), is in coincidence with the axis of rotation of lever (5), and transmits motion to shaped rack (9) through gear wheel (4) of rotatable lever (5). Rotatable lever (5) has bearings (3) and (6) which move individually over flat (7) and profiled (2) and (8) surfaces of rack (9). ^ EFFECT: simplified structure. ^ 2 dwg |
