AN EXAMINATION OF THE CONDITION OF WORKING SURFACES OF CRANKSHAFT CRANKPINS AND JOURNALS BASED ON THE MATERIAL FRACTION CURVES
Journal Title: Tribologia - Year 2016, Vol 265, Issue 1
Abstract
The paper focuses on the significance of the microgeometry of the working surfaces of crankpins and the main bearing journals on the durability and reliability of farm tractor engines. Alternative surface roughness parameters for the quantitative description of the material fraction curve are suggested to be applied as factors facilitating the evaluation of the performance properties of the working surfaces of the crankpins and main bearing journals. The results of graphometric profile examination of new crankshafts, the crankshafts recognized as run-in, and reworked ones have been provided and the assessment of the results concerned was basis for the evaluation of the proposed methodology for the examination of the microgeometry of the surfaces concerned. The results confirmed the suitability of slope indicators of straight lines describing the behaviour of material fraction as the evaluation parameters of performance properties of the working surfaces of the crankpins and main bearing journals.<br/><br/>
