ARTICULATED COUPLING Russian patent published in 2004 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention can be used in different drives for connecting shafts arranged at angle relative to each other. Proposed articulated coupling contains cam engaging with two yokes in form of semirings. Novelty is that cam be made in form of ball with two relatively perpendicular shaped slots made over circumferences, semiring is rigidly connected to each of said yokes, outer radius of semiring being equal to inner radius of yoke. Yokes with semirings are arranged in pairs in relatively perpendicular planes in said slots so that each yoke with semiring assembly encloses the cam. Cam is provided with mounting port. Semiring port. Semiring is secured on yoke by means of two dowels through mounting port. EFFECT: increased angle between connected shafts, improved reliability of coupling at any direction of load. 3 cl, 3 dwg
