Abstract
The analysis of lever mechanisms performance, having internal degrees of freedom conditioned by the presence of clearance in joints, has shown that clearances in the joints were the reason of appearance of additional dynamic forces. In order to eliminate the influence of clearances in joints on the origin of additional dynamic forces it is necessary to find regularities of pulse loading appearance. The analysis of the joint performance of a crank–bearing support with a clearance of crank-androcker mechanism of a cheek crusher was made. Based on the obtained results it was defined at which positions of mechanism links the contact surfaces changeover of a joint crank – bearing support appears. This allows to use rationally the mechanisms for the choice of clearances with resilient elements, which choose the clearance in a junction crank – bearing support during the cycle of work of crank-and-rocker, thus, preventing the appearance of the additional dynamic loadings
