Decoupling unit for driving mechanism e.g. pulley, in power transmission system, has groove treads of gear mesh encasing itself to ensure acceleration/resumption of driving mechanism while working in shearing/torsion zones

摘要

The decoupling unit has complementary gear meshes (102, 112) of gear meshes (101, 103) formed on respective sides (1c, 3c) of an opposing face support. Groove treads of the gear mesh encase itself to ensure acceleration/resumption of driving mechanism while working in multiple zones of shearing/torsion. The zones are in contact with supports at the time of rotation and distributed regularly.
