ANALYSIS OF THE INFLUENCE OF WEAR CRACK OF CHAINDRIVE ON STRESS IN ITS ELEMENTS

Pin joints of chain transmissions are areas of stress concentration, which can lead to the formation of cracks inthe links. This process often contributes to a critical weakening of the cross-section in the lugs of these links,which results in its damage and may lead to the failure of the entire drive. The article analyses the influenceof exemplary wear damages of chain transmission elements on the magnitude of stress concentration. Theimpact of the load, crack size, and its location on the level of stress increase was assessed. The location ofcracks in the lugs of chain plates transmission links which lead to the most significant increase in stress levelwas identified.
