Abstract

Abstract

Due to the particularity of its working nature, jaw crushers produce a lot of noise and vibration, which can cause fatigue damage to key machine components, reduce the structural characteristics and working stability of the whole machine, and indirectly affect the daily working environment and efficiency. Severe vibration can even cause irreparable damage to the device itself, thus reducing its service life. Vibration is a crucial factor affecting the regular operation of instruments and equipment, and intense vibration significantly affects the speed calibration accuracy of the crusher. Therefore, to reduce the jaw crusher's vibration frequency, this paper uses system modeling and C++ programming to analyze the vibration sources of the mechanical system, apply relevant knowledge of mechanical system dynamics to analyze the system's inertia force, and optimize the crusher's structure. By changing the eccentric counterweight and counterweight angle of the crusher flywheel, the centroid of the eccentric shaft, flywheel, and large pulley can meet the motion equation of the centroid of the jaw crusher's moving components. Experimental results show that this method can reduce the inertia force of the system to two-thirds of its original value.
