摘要
Depending on the form of mechanism, the hinge wear and rod end bearing wear are considered respectively, and the self-lubricating rod end bearing wear model are established. Then the over-center locking reliability analysis model of four bar linkage mechanism is built under the "effective lever length theory" and "continuous contact model" hypothesis, besides, a reliability analysis method of over-center locking considering the initial clearance and wear is presented. The results show that the failure probability of mechanism over-center locking will rapidly increase after a certain number of cycles; the reliability of mechanism over-center locking will be significantly improved by using self-lubricating rod end spherical plain bearing.
