Abstract

The invention discloses a gear shock excitation mechanism which belongs to a shock excitation mechanism applied to the engineering machinery. The gear shock excitation mechanism is provided with a sun wheel shaft, wherein one end of the sun wheel shaft is connected with an external drive mechanism through a spline, and the other end of the sun wheel shaft is connected to an end cover through a slide bearing; the sun wheel shaft is provided with a gear; the sun wheel shaft, a planetary wheel and an inner gear are meshed with each other; the outer end of the inner gear is connected with a working device; the planetary wheel is mounted on a planetary wheel frame; a central hole of a fixed eccentric block is an inner gear which is arranged on the sun wheel shaft and integrally connected with the sun wheel shaft. The central hole of a slide sleeve is an inner gear, and a movable eccentric block is arranged on the outer circle of the slide sleeve. The gear shock excitation mechanism has thefollowing advantages: 1, the shock excitation force is transferred among gears, and the bearing with great shock excitation force is not used; 2, a vibration shaft is connected with an eccentric block mechanism through a gear pair so as to meet the need for large-tonnage shock excitation force; 3, the oil temperature is reduced, and the working conditions of the vibration mechanism are improved; and 4, the service life is long, and the shock excitation force is much larger than that of the existing vibration mechanism.
