ACTUATING MECHANISM Russian patent published in 2010 - IPC B25J9/16 B25J13/00 

FIELD: machine building.

SUBSTANCE: actuating mechanism contains the first and the second driving pulleys, blocked for corotation, the first and the second driven pulleys, endless belt, interacting to the first and the second driving pulleys, and with the first and the second driven pulleys, electric motor, connected actuation for angular motion of the first and the second driving pulleys and movement of endless belt, driven member, supporting at least one of driven pulleys. The first and the second driving pulleys are implemented so that at its rotation circumferential speed of the first driving pulley differs from circumferential speed of the second driven pulley, and endless belt passing around driving and driven pulleys so, that difference between circumferential speeds of the first and the second driving pulleys activates movement of driving element. Additionally the first and the second driving pulleys are installed on the common axis.

EFFECT: invention reduces or excludes necessity in transmission gear between electric motor and driving pulley at usage in conditions of small and medium speeds, provides practical absence of lost motion.
