Downtimes associated with the replacement of the plain bearing liners because of their tear and wear are among the numerous technical reasons for relatively short-term but rather frequent downtimes in the conditions of operation of jaw crushers. The rapid wear of the liners is the result not only of contact friction between axle journals and liners, but also the action of dynamic forces. Dynamic forces that arise during the operation of jaw crushers are due to the presence of a gap in the kinematic pairing of the links (journals and bearing lining) and discrete speed values of the relative movement of the links inside the clearances of plain bearings. Thus, the reliable operation of the machine largely depends on the creation of conditions that ensure a gapless contact of the conjugated links. It was experimentally proved that the use of mechanisms for the selection of gaps with elastic elements, which during the whole cycle of operation of the crank and rocker mechanism select a gap in the joints of kinematic pairs, prevent the appearance of additional dynamic loads and, thereby, increase the reliability of the jaw crushers.
