Title Design of the electric luffing of dual linear output drive mechanism
Abstract
This topic requires a design driven by a single motor drive mechanism luffing dual linear actuator output in the work process requires dual linear actuators can automatically ensure synchronization and to ensure a smooth driving torque . This article is optimized to improve basic telescopic rod from the perspective of luffing mechanism, based on the principles to be applied to the automobile differential luffing mechanism to achieve dual linear synchronous motor-driven single horn. Can be obtained from the relevant issues needed to be lifting machinery , machine guns and institutions, the level of output control synchronous composition data and information throughout the organization point of view roughly motor, reducer, to achieve dual linear output gear, luffing putter, detection devices. After the input torque from the motor to obtain a substantially speed reducer , then the driving torque of the input means of the plunger to the two luffing angle of the arm of the plunger achieved by two amplitude to achieve the raising of the change . Choose different options for the design requirements , design and optimization of transmission schemes luffing drive mechanism , the drive mechanism of the transmission amplitude accuracy and dual output synchronous analysis, finite element strength parts luffing drive mechanism analysis , choose the best program analysis and calculation , the whole system design and use ANSYS software intensity stiffness analysis of key parts .
