EASILY CONNECTABLE COUPLING Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: coupling parts 1 and 2 are enclosed by bushing 3 for permitting axial displacement. A means for axial locking of bushing 3 is constructed as pin 4 and flexible plate 5 coupled with it. Groove 6 is made in inner side of coupling part 2. Outer side of the coupling part is provided with groove 7. The coupling part 1 has a projection and groove 8. The surfaces of the projection and groove are drawn by arcs of circumferences. Bushing 3 has cylindrical projection 9 which is answered to the groove. The projection of coupling part 1 is received in groove 6 of the coupling part, and projection 9 of bushing 3 and the grooves of the coupling parts are mated. The projection of the bushing can be constructed as a plate flexible member. The bushing can receive a rubber spacer having double- convex surface. The bushing can be provided with an additional projection. EFFECT: enhanced reliability. 5 cl, 20 dwg
