FIELD: machine building. ^ SUBSTANCE: mechanism contains circular shaft, helic shaft, located inside circular shaft and multitude of planetary shafts. Circular shaft allows internal threaded section and the first and the second annular pinion gears, which are tooth gear internally toothed. Solar shaft includes internal treaded section and the first and the second sun pinions, herewith sun pinions are external gears. Planetary shafts are located around the sun shaft, herewith each of shafts includes external threaded section and the first and the second planet wheels which are external gears. External threaded section of each planetary shaft is geared with internal threaded section of annular shaft and with external threaded section of sun shaft. Each the first and the second planetary wheels are geared correspondingly with the first and the second ring gears and sun wheels. Additionally planetary shafts are implemented with ability of providing of relative rotation of between the first planetary gear and the second planetary gear. ^ EFFECT: reduction of mechanism wear and effectiveness increase and conversion of rotary motion into translational motion. ^ 15 cl, 13 dwg |
