CENTRIFUGAL COUPLING Russian patent published in 2001 - IPC

FIELD: transport machine engineering, possibly systems for smoothly speeding up different types of transport vehicles, mechanisms needing shock free joining of driven shafts. SUBSTANCE: centrifugal coupling includes driving semicoupling and driven semicoupling in the form of drum in which rigid ring-halves may perform diametrical motion on guides. Ring halves made of magnetic material are placed in such a way that their adjacent different poles are turned one to another with possibility of separation one from another by action of centrifugal efforts and due to formation of ellipsoidal sliding path of vanes. Driving semicoupling is in the form of discs with tangential grooves freely mounted on splined hollow shaft and turned one to another by mirror fashion. Vanes consisting of plates engaging with ring halves are mounted in said grooves. Discs are joined with cylindrical sleeve having slits through which vanes may pass freely. Cylindrical sleeve made of dielectric material has outside in sectors between vanes metallic plates which are connected by means of conductor through splined hollow shaft with electric current conductive ring having lamella. Inner cavity of coupling is filled by 85-90% with lubricating liquid capable to change its viscosity at passing electric current through it. EFFECT: enhanced loading capacity, reliability and increased service life period of coupling. 5 cl, 3 dwg
