PIPE FITTINGS AND VALVES ELECTROMECHANICAL DRIVE

摘要

FIELD: mechanical engineering. SUBSTANCE: invention can be used in manufacture of pipe fittings and valve with remote control and is designed for use as electric drive to operate pipe fittings and valves. Proposed electromechanical drive contains electric motor with hollow rotor accommodating threaded bushing and screw spindle. Drive has fixed housing. Nut is placed between threaded bushing and screw spindle. Nut is made in form of threaded rollers placed in cages. Threaded bushing and cup are fixed in hollow rotor and are provided with splined grooves for reciprocating relative to each other. EFFECT: improved reliability of electromechanical drive. 2 dwg _
