MULTI-SPINDLE POWER DRIVER Russian patent published in 2006 - IPC B25B21/00 

FIELD: machine engineering.

SUBSTANCE: multi-spindle driver includes housing in which are arranged: motor, joined with motor clutch with yokes, intermittent motion mechanism and two spindles with heads. Driver is provided with planetary reduction gear arranged between motor and intermittent motion mechanism; intermittent motion mechanism joined to second spindle and to planetary reduction gear; differential mechanism kinematically coupled to first and second intermittent motion mechanisms and to first and second spindles; two reduction gears. One reduction gear is kinematically joined with first spindle and with first intermittent motion mechanism; second reduction gear is joined with second spindle and with second intermittent motion mechanism. First intermittent motion mechanism is joined with first spindle and with planetary reduction gear. One yoke of clutch is mounted in inlet shaft; second yoke is mounted with possibility of reciprocation motion in outlet shaft joined with differential mechanism.

EFFECT: enhanced accuracy and stability of axial forces of tightening.
