【Abstract】 Aiming at vibrational problem existent in crank shaft transmission in hole system drilling mechanisms, it is proposed that an internal balance method can be used to realize dynamic balance of the crankshaft and a kind of complete force balance of fluctuating forces and moments of crankshaft transmission mechanisms can be realized be means of “force balance method ”. The vibration of whole transmission mechanisms would be decreased or eliminated and machining precision of hole system could be improved.更多还原
