FIELD: machine building.
SUBSTANCE: ends of proposed spring can be connected to the parts of oscillatory system. Ends of said wrap springs are connected to connection flanges. Recess is made at every said flange to rule out the contact of the spring extreme turns with flanges at spring operation. Note here that said extreme turns are bent-under and cut so that said compressed spring with flanges at maximum load has its turns not contacting. Said spring can feature both cylindrical and shaped cross-section. Threaded bores are made at spring extreme turn flat surfaces of contact with connection flanges. Said bores are used to secure connection flanges via openings opposite the former to spring extreme turns by screws. Note here that every connection flange is secured to extreme turns by at least two screws. Proposed spring differs from know designs in that screw heads are locked by welding said heads to connection flanges.
EFFECT: higher reliability of connection of flanges to spring extreme turns.
