FIELD: mechanical engineering. SUBSTANCE: device comprises a screw pair which consists of a gear which embraces the screw and pinion. The screw is provided with a stop member. The nut has a gear toothing. The number of teeth of the toothing is not equal to the number of teeth of the gear. The pinion simultaneously interacts with the gear toothing of the nut and gear. The arrester is mounted on the gear and interacts with the stop member of the screw. In addition the pinion can be provided with two gear zones of unequal number of teeth. Each gear zone interacts with their gear toothing of the nut and gear, respectively. EFFECT: decreased sizes. 2 cl, 1 dwg |
