磨损往往导致轴承零件逐渐损坏,***终导致轴承零件尺寸精度损失等相关问题。磨损引起的故障不仅意味着更换轴承。由于工作环境的变化,其余磨损状态可能占主导地位。失效机理和磨损会导致应力集中和裂纹。

Wear often leads to progressive damage of bearing parts, *** eventually leads to the loss of dimensional accuracy of bearing parts and other related problems. Faults caused by wear not only mean replacing bearings. Due to the change of working environment, other wear states may dominate. Failure mechani*** and wear will lead to stress concentration and cracks.

在适当的润滑条件下,冷压塑性会使淮安SKF轴承副表面变形、变平。在这种情况下,轴承可以达到预期的使用寿命。然而,当润滑条件恶化时,轴承的内部被制造出来。滚动表面金属与金属的接触导致摩擦力增大,导致轴承内部局部变形和摩擦han接。

Under appropriate lubrication conditi***, cold-pressing plasticity will deform and flatten the surface of Huaian SKF bearing pairs. In this case, the bearing can achieve the expected service life. However, when lubrication conditi*** deteriorate, the interior of the bearing is manufactured. The contact between metal and metal on rolling surface leads to the increase of friction force, which leads to local deformation and friction Han joint in bearing.

轴承零件的接触面和相对接触面之间的磨粒会导致磨损。尖锐的磨粒会产生明显的***,这是早期失效的根源。磨粒主要来自轴承或机器系统内部。例如,内部润滑的纯度、轴承安装的清洁度以及轴承出厂前的清洁度。

The abrasive particles between the contact surface and the relative contact surface of the bearing parts can lead to wear. Sharp abrasive particles can produce ***ious wrinkles, which is the root of early failure. The abrasive particles mainly come from the inside of the bearing or machine system. For example, the purity of internal lubrication, the cleanliness of bearing installation and the cleanliness of bearings before they le***e the factory.

淮安SKF轴承部件的裂纹是由过载或循环载荷引起的。冶炼和加工技术也可能导致开裂。除夹杂和氧化物引起的裂纹外,冶炼引起的裂纹不太可能进入下一阶段。

Cracks in Huaian SKF bearing components are caused by overload or cyclic loads. ***elting and processing technologies may also lead to cracking. Besides the cracks caused by inclusi*** and oxides, the cracks caused by ***elting are unlikely to enter the next stage.

轴承加工中的后续裂纹通常与热处理和磨削工艺有关。如果裂纹进入下一个制造过程,裂纹将在随后的加工过程中迅速扩展。但也有例外。如果未检查***终研磨阶段产生的裂纹,则将其带到操作设备上。为了消chu上述情况,裂缝的主要问题是an全。

The subsequent cracks in bearing processing are usually related to heat treatment and grinding process. If the crack enters the next manufacturing process, the crack will propagate rapidly in the subsequent processing. But there are excepti***. If the cracks in the final grinding stage of *** are not checked, they are brought to the operating equipment. In order to eliminate the above situation, the main problem of cracks is an quan.

许多使用新型接触淮安SKF轴承润滑脂的用户不希望只通过关注油滴和忽略其ta油滴来选择高温黄油。滴点是衡量润滑脂高温性能的重要指标,但不是wei一的指标。

Many users who use the new SKF bearing grease do not want to choose high-temperature butter only by focusing on oil droplets and ignoring their TA oil droplets. Dropping point is an important index to measure the high temperature performance of grease, but it is not Wei1's index.

例如,许多轴承润滑脂制造商使用用户的观点“高降点耐热性”。在产品配置文件中,它们通常在外部突出显示“放置点”。它说“380摄氏度的下降点”非常有吸引力。这似乎是传说中的“高温润滑脂”,但它们所能达到的实际温度甚至可能不低于150摄氏度。

For example, many bearing grease manufacturers use the user's view of "high drop point heat resistance". In product configuration files, they usually highlight "placement points" externally. It says that the "drop point of 380 degrees Celsius" is very attractive. This seems to be the legendary "high temperature grease", but the actual temperature they can reach may not even be less than 150 degrees Celsius.

一般来说,淮安SKF轴承滴点高的润滑脂相对工作温度较高,但实际工作温度一般在滴点以下30~50之间。高温润滑脂能否承受高温取决于基础油的选择。良好的基础油对润滑脂的高低温性能起着决定性的作用。

Generally speaking, the lubricating grease with high dropping point of Huaian SKF bearings has higher relative working temperature, but the actual working temperature is generally between 30 and 50 below the dropping point. Whether high temperature grease can withstand high temperature depends on the choice of base oil. Good base oil plays a decisive role in the high and low temperature performance of grease.

此外,它还与油的增稠方法和添加剂的含量有关。

In addition, it is also related to the thickening method of oil and the content of additives.
