FIELD: machine building. ^ SUBSTANCE: arrester consists of shaft and of stationary case. At least two units in form of rectangular bars with slots are secured on the case. Stop blocks enter the slots of the bars. The stop blocks are also made in form of rectangular bars with vertical cylinder pins. Screw mechanisms of stop block lifting and retainer screws are attached to the units. A disk with uniformly made orifices is mounted on the shaft; diametre of the orifices is larger, than diametres of the pins. Length of the unit slot exceeds length of the stop block at a value exceeding distance between centres of two neighbour orifices of the disk. ^ EFFECT: increased operational reliability. ^ 5 dwg |
