Resilient coupling for shaft boring machine

The utility model discloses a resilient coupling for shaft boring machine relates to the shaft coupling field, and the improvement of a concretely relates to resilient coupling's spring structure is technological. Including initiative hub body and driven hub body, initiative hub body's tip still is equipped with the ring flange and prevents twising reverse the backing plate, and driven hub body tip is the toper round platform, installs dish -shaped copper spring on the initiative hub body, and dish -shaped copper spring is a thin slice shape structure, and dish -shaped copper spring is the toper structure, and dish -shaped copper spring conical surface tip has four rectangle breachs along the circumference, two dish -shaped copper spring conical surface tips are a set of to closing the constitution, and at least a set of dish -shaped copper spring suit prevents twising reverse the backing plate and passes through bolt and dish -shaped copper spring coupling on initiative hub body. The utility model provides a
