Screwer test bench comprising a thin disk brake

摘要

A screwer test bench includes a coupling designed for connection with the head of a screwer and connected to a controlled braking unit and a sensor unit for detection of mechanical magnitudes transmitted between the coupling and the braking unit. The braking unit includes a thin cap constrained to said coupling at least in the direction of rotation and arranged between a first pressure surface thrust axially against the cap by an actuator and a second fixed opposition surface.
