Movement analysis on steel wire rope of continuous conveyor with disc-tube assembly

The steel wire rope of continuous conveyor with disc-tube assembly is droved by the driving wheel. When the driving wheel rotates, the gear is combined to the con- nection disc in turn, promoting the connection disc to move in succession. Turning the whirling torque of driving wheel into the straight-line traction force. When the steel wire rope is winded by the driving wheel some winded along the circumference, others winded along the straight line. Used motion subject law, this article analyses the change of the velocity and the acceleration of the steel wire rope in the straight movement, and observe the mathematics’ model of velocity and acceleration.
