Described two pinions are connected with the output of reductor by same high speed shaft, and high speed shaft makes two pinion interlocks.
Described two pinions are respectively by the output conducting of a high speed shaft and a reductor, the quantity that is motor, reductor and high speed shaft is all two, a motor and a reductor conducting, the output of a reductor is connected with a pinion by a high speed shaft.
Described gear wheel can be eccentric gear.
All be provided with counterweight on described two one-throw crankshafts.
Characteristics of the present utility model are to be provided with gear wheel and one-throw crankshaft on the crank gear case simultaneously, and increase counterweight on one-throw crankshaft, the gear wheel be contained on one-throw crankshaft also can be made eccentric gear, thereby on structural design, avoided affected by tube outer diameter, make the mistake of slider-crank mechanism apart from designing within zone of reasonableness, production tube also can pass through the crank gear case smoothly, thereby inertia force and the moment of inertia of mechanism kinematic have significantly been reduced, rigidity and the stability of equipment have been strengthened, improved the main frame speed of service, for improving output, be of great importance.
