触摸南京SKF轴承疲惫磨损的失效领域

南京SKF轴承接触疲劳失效是由轴承工作表面上的交变应力引起的。接触疲劳脱落发生在轴承表面，常伴有疲劳裂纹。首先，较大程度的交变剪应力出现在接触表面以下，然后传播到表面，形成不同形状的脱落，如点蚀或点蚀脱落，脱落变小。它被称为浅降膜。随着离层的逐渐扩展，它向深部延伸，形成深部脱离。层次脱落是疲劳的根本原因。

The contact fatigue failure of SKF bearing in Nanjing is caused by alternating stress on the working surface of the bearing. Contact fatigue shedding occurs on the surface of bearings, often accompanied by fatigue cracks. First, a large degree of alternating shear stress appears below the contact surface, and then propagates to the surface, forming different shapes of shedding, such as pitting or pitting shedding, shedding becomes ***aller. It is called a shallow falling film. With the gradual expansion of the abscission layer, it extends to the deep part and forms a deep detachment. Falling off level is the root cause of fatigue.

磨损失效是由于南京SKF轴承金属表面失效引起的表面相对滑动。连续磨损会逐渐损坏轴承零件，导致轴承尺寸精度损失等相关问题。磨损会影响形状变化、协同空隙的增大和工作表面形态的变化。

The wear failure is due to the relative slip of the surface caused by the failure of the SKF bearing metal surface in Nanjing. Continuous wear will gradually damage bearing parts, resulting in bearing dimensional accuracy loss and other related issues. Wear will affect the shape change, the increase of synergistic void and the change of working surface morphology.

它会影响整理剂或使其受到一定程度的污染，形成完全失去平滑功能的轴承，使南京SKF轴承的旋转精度损失甚至不能工作。适当地。磨损失效是轴承较常见的失效形式之一。根据磨损模式，轴承可分为较常见的磨料磨损和粘着磨损。

It will affect the finishing agent or cause it to be polluted to a certain extent, forming a bearing that completely loses ***oothness function, so that the rotary precision of Nanjing SKF bearing will be lost or even can not work. Properly. Wear failure is one of the most common failure modes of bearings. According to wear mode, bearings can be divided into more common abrasive wear and adhesive wear.

磨料磨损是指由于硬质***或硬质***或碎屑在金属表面的挤压、与南京SKF轴承表面的相对运动接触以及轴承表面的沟槽磨损而引起的磨料磨损。硬质颗粒或***可能来自主机的内部或主机系统的其余相邻部分，并通过光滑介质送入轴承。熟悉轴承的精度和误差。

Abrasive wear refers to the abrasive wear caused by the extrusion of hard foreign bodies or hard foreign bodies or debris on the metal surface, relative motion contact with the surface of Nanjing SKF bearings and groove wear on the surface of bearings. Hard particles or foreign bodies may come from the interior of the main engine or the remaining adjacent parts of the main engine system and are fed into the bearing through a ***ooth medium. Familiar with bearing accuracy and error.

粘着磨损是指由于碰撞表面上的小突起或***而在碰撞表面上施加的不均匀力。当光滑条件严重恶化时，局部碰撞产生的热量容易形成碰撞表面的局部变形和碰撞南京SKF轴承表面的微电焊和接合现象。

Adhesive wear refers to the uneven force exerted on the collision surface due to ***all protrusi*** or foreign bodies on the collision surface. When the ***ooth condition deteriorates seriously, the heat generated by the local collision is easy to form the local deformation of the collision surface and the micro-welding and bonding phenomenon of the collision surface of Nanjing SKF bearing.

当冲击表面严重时，金属可能部分熔化，作用在接触南京SKF轴承表面上的力将导致一些冲击焊缝从基座上移除。撕裂增加，塑性变形增加。这种粘附和撕裂粘合循环形成粘着磨损。一般来说，粘着磨损称为磨损，严重的粘着磨损称为咬合磨损。

When the impact surface is severe, the metal may partly melt, and the force acting on the surface of the SKF bearing in Nanjing will cause some impact welds to be removed from the base. The tear increased and the plastic deformation increased. This adhesion and tear adhesion cycle forms adhesive wear. In general, adhesive wear is called abrasion, and severe adhesive wear is called occlusal wear.
