Vibration exciter transmission structure and high-frequency breaking hammer

The utility model discloses a vibration exciter transmission structure and a high-frequency breaking hammer. The hydraulic motors are coaxially connected to the two ends of the driving shaft of the vibration exciter, and the expensive high-power hydraulic motors are replaced with the multiple low-cost low-power hydraulic motors. Driving force is increased, cost is reduced, torque at the two ends of the driving shaft can be balanced, and internal stress of the driving shaft is reduced. Meanwhile, the eccentric blocks on the eccentric wheels are symmetrically arranged, so that the stress at the two ends of the rotating shaft is balanced, the rotating shaft and bearing structures are optimized, and the abrasion of the rotating shaft is reduced. And the gear does not bear torque any more, and the gear can adopt a small module, so that the weight of the gear is reduced, and the cost is reduced. The working efficiency of the high-frequency breaking hammer is improved, and the service life is prolonged. 本实用新型公开了一种激振
