ROTARY-TO-RECIPROCAL MOTION CONVERTER Russian patent published in 2001 - IPC

FIELD: conversion of one kind of motion to other. SUBSTANCE: converter capable of converting rotary to reciprocal motion when axes of revolution and directions of reciprocation are parallel without using additional mechanisms has guide rod carrying movable shorted-out electromagnetic coil; one end of guide rod is rigidly joined with fixed electromagnetic coil whose one end is fixed to reset spring; other end of spring is fixed to movable coil and fitted onto guide rod; the latter is placed in C-shaped cavity in longitudinal section of ferromagnetic core mounted on motor shaft; end parts of core are made in the form of segments in cross- sectional area. Guide rod is made of ferromagnetic material. Segments of end parts of core are of variable thickness. End ferromagnetic segments are alternating with those made of nonmagnetic material. EFFECT: simplified design; enlarged functional capabilities. 4 cl, 2 dwg
