FIELD: process engineering.
SUBSTANCE: coupling serves to couple arbor shaft, particularly, saw arbor, with machine tool spindle or adapter coupled with spindle. Note here that four drives are arranged crosslike between said assembly units to transmit rotary motion which, when clamped, interact with four recesses. Every drive has flat surface on torque transmission side that, when clamped, bears against recess wall. Note also that drive opposite side has smaller surface bearing against appropriate recess wall with geometrical or friction closure. Mind that fast-clamp appliance is arranged for axial clamping of arbor and spindle or adapter.
EFFECT: simplified manufacture and use.
