The excessive wear of a journal shaft can be caused by many factors, for example, working conditions (e.g., temperature, slip speed, the type of lubricant), pressure, the type of material used on the bearings and shafts and their roughness, as well as contamination remaining in the system. This paper presents the roughness profiles co-operating with a rubber (NBR) and polytetrafluoroethylene (PTFE) bushes. The conditions of cooperation between the two materials tested in the sliding combination with the stainless steel journal were the same in each pair of bearings (PV); therefore, the comparison of their wear depends only on the material properties of the bush and the deformation of the journal shaft caused by the bending moment. To assess the size of the journal shaft, they were tested using a profilograph. In addition to the journal shaft, bearings were also evaluated, the wear level of which was noticed without the use of specialized equipment.
轴承轴的过度磨损可能由多种因素引起，例如工作条件（如温度、滑动速度、润滑剂类型）、压力、轴承和轴所用材料及其表面粗糙度，以及系统中残留的污染。本文研究了橡胶（NBR）和聚四氟乙烯（PTFE）衬套在配合使用时的表面粗糙度特征。每一对轴承（PV）在与不锈钢轴的滑动组合条件下，两种材料之间的配合状态均保持一致。因此，其磨损程度的比较仅取决于衬套的材料特性以及由弯矩引起的轴颈轴变形。为了评估轴颈轴的尺寸，使用了轮廓仪进行测试。除了轴颈轴外，还对轴承进行了评估，其磨损程度无需使用专用设备即可观察到。 |
