Overload protection type electrical starting duplicate gear and starting system

The invention discloses an overload protection type electrical starting duplicate gear and a starting system. The overload protection type electrical starting duplicate gear comprises a duplicate gear shaft, a gear body I and a gear body II, wherein the gear body I and the gear body II are arranged on the duplicate gear shaft in a drive matching mode. The duplicate gear shaft is sleeved with the gear body II so that an inner conical surface of the gear body II and an outer conical surface of the duplicate gear shaft can form a conical surface pair. The gear body II has axial force for locking the conical surface pair and enabling the sliding torsion value of the conical surface pair to be larger than or equal to the electrical starting torsion value. When the reverse dragging phenomenon occurs and the torsion value exceeds the largest static friction force between the conical surfaces due to the fact that an engine suddenly slows down or stops under heavy loads and great inertia in the high-speed running process, the inner conical surface and the outer conical surface can slide, in other words, the gear body II and the duplicate gear shaft can slide relative to each other, and therefore the gear and a starting clutch of the whole electrical starting system can not be damaged, and the overload protection function is achieved. In the use process, the taper angle, the roughness of the conical surfaces and the axial force can be set according to the actual requirements, and therefore the required largest static friction force can be set.
