The inner cone movement of the inner cone is cyclical in nature, as a result of which the body performs similar in frequency but opposite in phase oscillations. Since the upper half coupling 11 is installed in the base of the housing 1, then. in the process of oscillation, it receives radial, axial and angular displacements the lower half of the coupling half 13,

When the crusher operates in the nominal mode, the rotation of the Lolufta 11 and 13 relative to each other does not exceed 5.3, therefore the cylindrical shears 14 of the lower semi-coupling 13 do not touch the walls. keyway 12 is not involved in the transmission of torque. This allows the electric clutch Y to retain damping:

; During acceleration and deceleration of the internal crushing cone, when the coupling torque may exceed the permissible maximum values, the cylindrical fingers 14 of the lower coupling 13 abut against the walls of the groove 12 of the coupling half 11 and transfer the torque that provides protection
