ANALYSIS OF THE PROCESS OF WEAR OF A BRONZE–ALLOY CAST IRON KINEMATIC PAIR UNDER MIXED FRICTION CONDITIONS
Journal Title: Tribologia - Year 2011, Vol 238, Issue 4
Abstract
The paper presents the results of model studies of wear under mixed friction conditions of the worm–worm rack kinematic pair, where the worm is made of bronze CUA19Fe3, while the worm rack is of alloy cast iron. This pair is applied in the (worm–worm rack) feed mechanisms of heavy-duty machine tools. The experiment was conducted at variable cast iron hardness values and friction process rates. The distribution of wear along the friction path was determined for both elements of the tribological pair. The results are presented in diagrams and in the form of the relationship of wear intensity as a function of the parameters examined in the experiment.<br/><br/>
