A SAFETY DEVICE IN TORQUE TRANSMISSION SYSTEM

摘要

A torque transmission system for coupling an extruder screw shaft having a critical torque level with the output shaft of a driving means, the torque transmission system comprising a coupler configured to engage with the output shaft of the driving means and an adaptor configured to be engaged by the coupler, the adaptor further configured to engage the extruder screw shaft, the adaptor defining a pre weakened area designed to rupture at a torque level less than the critical torque of the extruder screw shaft.
