To identify the strength properties of a block structure including a bearing pair cage and the lubricated bearing itself, a model of a bearing with a defect is considered. The cage is a deformable base with a thin coating having defects. The coating is under the influence of a lubricant, which under operating conditions loses viscosity and can be modeled by a thin layer of an ideal incompressible fluid, on which the vertical external pressure from the bearing is applied. To study the local properties of the bearing in the vicinity of the defect, the base of the cage is considered as deformable layer with a defective coating containing on top a layer of ideal incompressible fluid. It is assumed that the coating has the most complex latent defect described by a crack, the plane of which is perpendicular to the boundary of the coating. The described block structure is investigated by the block element method, and the features of bearing behavior are revealed.

涂层不良的润滑轴承的强度特性

为了确定包括轴承对保持架和润滑轴承本身的块状结构的强度特性，考虑了带有缺陷的轴承模型。保持架是可变形的基座，带有薄薄的缺陷涂层。该涂层受润滑剂的影响，该润滑剂在工作条件下会失去粘度，并且可以通过理想不可压缩流体的薄层进行建模，并在该薄层上施加来自轴承的垂直外部压力。为了研究轴承在缺陷附近的局部性能，保持架的底部被认为是可变形层，其缺陷涂层的顶部包含一层理想的不可压缩流体。假定涂层具有由裂纹描述的最复杂的潜在缺陷，裂纹的平面垂直于涂层的边界。
