Abstract
The invention relates to an elliptic vibration machine with parallel shafts and double excitation motor. The elliptic vibration machine mainly consists of a feed hopper, a vibration body, first and second excitation motors, a swing motor base, swing motor base vibration damping springs, a vibration body support spring, a base, and the like. The first excitation motor is directly arranged on the vibration body, and the second excitation motor is arranged on the swing motor base connected the vibration body, through a hinge. Under the action of a group of vibration damping springs between the swing motor base and the vibration body, the swing motor base and the second excitation motor swing together in a certain angle range through the excitation force generated by the second excitation motor on the swing motor base. The generated centrifugal inertia force and the excitation force of the excitation motors are combined to ensure that the vibration body does an approximately linear motion. The vibration body does a circular motion through the excitation motors directly arranged on the vibration body. The two motions are combined to form an elliptic motion of the vibration body. The elliptic vibration machine with the parallel shafts and the double excitation motors has high strength of the vibration body, even force output of the two motors and capability of realizing the needed elliptic motion.
