The jaw crusher run in high speed and heavy load, high requirements for the working device performance. This paper analyse the gap between the eccentric shaft and movable jaw. Firstly, jaw crusher establish geometric model, the kinematic pair clearance two state model theory, establish the clearance contact model and the clearance friction model, based on the ADAMS software, establish the gap with the working device in the jaw crusher models. The jaw of the velocity and acceleration and the eccentric shaft and the movable jaw contact force dynamic characteristics analysis of gap is not at the same time, analysis of the results showed that gap has great influence on the dynamic characteristics of mechanism. |
