江苏INA轴承失效的多重分析 来源:御狮轴承   点击:次   日期:2018-06-14 15:26

江苏INA轴承磨损失效是由表面之间的相对滑动摩擦引起的,从而导致金属在工作表面上的连续磨损。连续磨损会导致轴承零件的渐进损坏,从而导致轴承尺寸精度的损失和其他相关问题。磨损会影响形状变化,间隙的增大和工作面的表面形态的改变会影响润滑剂或使其在一定程度上受到污染,并导致润滑功能的完全丧失,从而导致轴承的旋转损失。精度,甚至正常操作。

The wear failure of INA bearing in Jiangsu is caused by the relative sliding friction between the surfaces, resulting in the continuous wear of metal on the working surface. Continuous wear can cause progressive damage to bearing parts, resulting in loss of bearing dimensional accuracy and other related problems. The wear will affect the shape change, the increase of the gap and the change of the surface morphology of the working face will affect the lubricant or make it be polluted to a certain extent, and lead to the complete loss of the lubrication function, which leads to the rotation loss of the bearing. Precision, even normal operation.

江苏INA轴承接触疲劳失效是承受交变应力的轴承表面失效。接触疲劳剥落发生在轴承工作表面上,经常伴随着疲劳裂纹,其首先来自接触表面底部的最大剪切应力,然后延伸到表面以形成不同的剥落形状,例如点蚀或剥离,和PE。鳞片,浅。剥落面逐渐膨胀,倾向于向深层扩展,形成深剥落。深部剥落是接触疲劳失效的疲劳源。

The contact fatigue failure of INA bearing in Jiangsu is the failure of bearing surface subjected to alternating stress. Contact fatigue spalling occurs on the working surface of the bearing, often accompanied by fatigue cracks, which first comes from the maximum shear stress at the bottom of the contact surface, and then extends to the surface to form different peeling shapes, such as pitting or peeling, and PE. Scales, shallow. The spalling surface expands gradually, tends to extend to the deep layer and form deep spalling. Deep exfoliation is the fatigue source of contact fatigue failure.

江苏INA轴承硬颗粒或异物可能来自宿主身体或来自宿主系统的其他部分。轴承精度误差的相关知识。粘着磨损系统是由摩擦表面上的微突起或异物引起的摩擦表面上的不均匀力。当润滑条件严重恶化时,局部摩擦是由局部摩擦和局部变形引起的摩擦表面和摩擦微焊接引起的。表面金属可以部分熔化,局部摩擦焊接点来自基体。塑性变形是由身体的撕裂引起的。

Jiangsu INA bearing hard particles or foreign bodies may come from the body of the host or from other parts of the host system。 The relevant knowledge of the error of bearing precision。 The adhesive wear system is an uneven force on the friction surface caused by micro protrusions or foreign bodies on the friction surface。 When the lubrication condition is seriously deteriorated, the local friction is caused by friction surface and friction micro welding caused by local friction and local deformation。 The surface metal can be partially melted and the local friction welding point comes from the substrate。 Plastic deformation is caused by the tear of the body。

江苏INA轴承断裂失效的主要原因是缺陷和过载两个因素。当外部载荷超过材料强度极限时,零件的断裂称为过载断裂。超载的主要原因是主机突然损坏或安装不当。微裂纹、缩孔、气泡、大杂质、过热组织和局部烧伤等轴承缺陷也会在冲击过载或严重振动过载的缺陷中引起断裂,而江苏INA轴承则称为缺陷断裂。

The main cause of failure of INA bearing in Jiangsu is two factors, defect and overload。 When the external load exceeds the limit of material strength, the fracture of the part is known as overload fracture。 The main reason for overload is the sudden damage or improper installation of the main engine。 Bearing defects such as micro cracks, shrinkage holes, bubbles, large impurities, superheated tissues and local burns also cause fracture in the defects of impact overload or serious vibration overload, and the INA bearing in Jiangsu is called defect fracture。

在工作中,由于外部或内部因素的影响,江苏INA轴承原有的协调间隙被改变,精度降低,甚至“咬”也被称为间隙变化的失败。在不稳定状态下,由于干扰、安装、膨胀、温度升高等瞬态过载,如残余奥氏体和残余应力,是造成间隙变化失效的主要原因。

In the work, due to the influence of external or internal factors, the original coordination gap of the Jiangsu INA bearing is changed, the precision is reduced, and even "bite" is also called the failure of the gap change。 In the unstable state, the transient overload, such as residual austenite and residual stress, is the main reason for the failure of the gap change due to interference, installation, expansion and temperature rise。

如果是江苏INA轴承润滑良好,适当保护免受杂物和湿气的影响。不应使用密封件。然而,最好在轴承箱打开时检查轴承并定期检查油封。检查轴承附近油封的状况,确保它们足以防止液体或气体渗入热液体或沿轴线腐蚀。更换后立即更换轴承和油封。

If the INA bearing of Jiangsu is well lubricated, it is properly protected from sundries and moisture. Seals should not be used. However, it is best to check the bearing when opening the bearing box and check the oil seal regularly. Check the condition of the oil seal near the bearing to ensure that they are sufficient to prevent liquid or gas from infiltrating into the hot liquid or corroding along the axis. Replace bearing and oil seal immediately after replacement.
