Outside.
Further, the modulus of the gear ring is 1.75, the number of teeth 45；The modulus of centre wheel is on the output shaft
1.75, the number of teeth 15；The modulus of the planetary gear is 1.75, the number of teeth 15.
Further, disk spring is installed in the disk spring seat.
The beneficial effects of the utility model are compared with prior art：
1, limit handle can prevent from rotating with the pinion stand of gear ring one, and so that planetary gear is rotated around central gear and carry out band
Dynamic driving square toes rotation can not output torque if not limiting handle to output torque.
2, limit torque multiplier is when overload or mechanical breakdown cause required torque to be more than setting value, it is to skid
The torsion that form limitation transmission system is driven voluntarily restores to be coupled after overload condition disappears.This prevents machineries to damage
It is bad, avoid expensive shutdown loss.It limits torque multiplier and uses disk spring load-type friction surface, bullet is adjusted with nut
Spring force presets its sliding torque.
