UNIVERSAL JOINT COUPLING Russian patent published in 2001 - IPC

FIELD: transport engineering. SUBSTANCE: invention relates to devices for connecting misaligned shafts changing their relative position in operation. Proposed device has forks installed on shafts to be connected, crosses and bearings. Forks installed on shafts are made in form of bushings with trunnions over periphery. At least one of forks is installed on shaft through splined bushing to provide axial displacement. Crosses are made in form of rings with trunnions over periphery and holes in which forks are fitted on bearings. Trunnions of crosses are connected by means of bearings with coupling members fastened to each other. Crosses and coupling members are provided with side recesses at holes. EFFECT: increased efficiency of compensation for radial, axial and angular displacement of connected shafts. 3 dwg
