IMPACT-ACTION ELECTROMAGNETIC MACHINE Russian patent published in 1998 - IPC

FIELD: mechanical engineering; impact-action machines. SUBSTANCE: machine has housing accommodating magnetic circuit with coil. Spring-loaded guide bushing with striker and return spring is arranged in magnetic circuit and is installed for axial displacement. Buffer and axle box with working tool are installed in guide bushing. Ring pole adjoins coaxially end face part of magnetic circuit at side of buffer and encloses guide bushing to provide passing of magnetic flux through striker and buffer. Cross section area of ring pole is smaller than that of magnetic circuit. Buffer is ferromagnetic. Ring pole can be made integral with magnetic circuit. EFFECT: enlarged operating capabilities. 2 cl, 2 dwg
