FIELD: mechanical engineering.
SUBSTANCE: invention relates to devices for transmission of rotation and it can be used in drives of heavy loaded processing equipment. Proposed hydrostatic safety flexibly damping coupling contains two coupling members mechanically intercoupled by transfer device and hydraulic cylinder. Hydraulic cylinder is connected with damper and hydraulic accumulator through controllable hydraulic distributor with system of control according to torque on coupling. Inputs and outputs of hydraulic distributor are made for alternate connection of hydraulic cylinder with damper and hydraulic accumulator. Transfer device is made in form of screw-nut mechanism and splined bushing. Screw is secured on one coupling member and is coupled with nut and hydraulic cylinder, and splined bushing is secured on other coupling member, being coupled with nut by splined joint. Said mechanism is provided with non-self-braking thread.
EFFECT: provision of larger angle of relative turning of coupling members; improved of damping properties of coupling, reduced contact stresses in parts of transfer device; improved reliability and increased service life of coupling.
