WINCH WITH IMPROVED ROPE TENSIONING MECHANISM Russian patent published in 2022 - IPC B66D1/50 B66D1/12 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering, in particular to winches. The winch contains a drum on which the rope is wound, an electric motor and the first and second rollers. The rollers are in contact with the rope and are located on both sides of it. The electric motor is capable of driving the first roller into rotation. A clutch is included in the kinematic chain between the electric motor and the first roller. The torque transmitted to it is limited to such a given value at which the interaction of the first roller with the rope occurs without slipping. The clutch contains a driving and driven shafts, as well as a spring, which has a frictional connection with one of the specified shafts and contacts its end section with the other of the specified shafts. In this case, the end section of the spring is able to perceive the force in that circumferential direction of the spring, in which the weakening of the said frictional connection is ensured.

EFFECT: reduced wear of rollers and rope.
