FLEXIBLE COUPLING Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: driving coupling part is constructed as spline shaft 1 and two flanges 2 and 3. One of the flanges is rigidly secured to spline shaft 1 and the other one is mounted on the shaft for axial movement. The driving coupling part is constructed as sleeve 4 provided with openings 5 in its bottom and mounted concentrically to the spline shaft. Flexible link 6 passes through openings 5 made in the sleeve and openings 7 made in the flanges of the driving coupling part. Semicircular slide blocks 8 serve as guides for the flexible link. The flexible link is tensioned by compression spring 9 which is in contact with fixed flange 2 by its one end and with movable flange 3 of the driving coupling part by its other end. In rotation, tensions of branches of flexible link 6 level off. EFFECT: enhanced reliability. 2 dwg
