The shaft structure of the aligning bearing, just like the last time I encountered a spindle, in general, the strength ball aligning bearing is composed of a whole whole, and the high speed rolling, sometimes it is not low. Thermal efficiency. If such a condition is not removed in the first time, it will cause the angle to approach the ball inlet bearing to overheat, and cause the high temperature bearing to rise relative to the temperature of the part and cause high temperature deformation, which may cause the spindle and the tailstock to be more or less different. High, this not only stimulates the reliability and processing safety of high temperature bearings, but also damages the high temperature bearing temperature.

Weary life means that a group of high-temperature bearings of the same type will operate under the same conditions, and those of the angular contact ball thrust bearings will not form the total number of revolutions caused by rolling fatigue. When the speed of rotation is constant, the total working time is used to mean fatigue.

When studying the life of high temperature bearing, I didn't just want to be tired. I have to think carefully according to the rich effect of the shaft and combine several options. For example, the oil length of deep groove ball bearings. The hateful voices, the ages, etc., vary according to the characteristics, and the ability to transport is different from time to time. Because of this, each has its own limit.

Therefore, only investigating the angle close to the ball thrust bearing damage, it is very difficult to understand the real cause of the injury. Depressed, if you understand the operation parts of the ball aligning bearing, the environment, the structure around the thrust bearing, and understand the situation after the accident, combined with the negative impact of the deep groove ball bearing and several aspects of the problem, it will definitely avoid The same incident is the recurrence of the incident.

The corner touch ball thrust bearing can not be properly possessed, if the deliberate consideration of the high-speed bearing damage degree, product performance, very important, the role of weather, to the next maintenance period. If you have the following strengths, you can't use them anymore. You have to replace the high-speed bearings that push forward. There are cracks or gaps in the inner ring, the outer ring, the rolling elements, and any of the frames.

Wear and tear damage is one of the damage patterns caused by various high-speed bearings. According to the wear symptoms, the most common abrasive wear and adhesive wear are generally available.

Oil film resistance evaluation professional technology

Important: The same criteria can be used for weather conditions under the same conditions. It has a poor diagnostic effect on the surface of the surface, such as shedding, indentation, cracks, etc.

Use limit: It can be exposed on the axis of rotation.

Non-stop vibration check diagnostic professionals

Broken bridge aluminum fire protection function: The application of constant jitter treatment technology is extremely large; online detection can be realized; the judgment is fast, and the diagnosis principle has been achieved.

Application category: It is very suitable for fault monitoring of angular contact ball bearings in rotating parts.

. Ferrography surgery technology

Highlights: The machine does not need to be disassembled; the delivery is low, the effect is good; the first fatigue can be considered to be the oil-free thrust bearing; the wear performance can be honed.

Scope of use: The angle of lubrication of the lubricating oil that is close to the lubrication is close to that of the deep groove ball bearing of the ball. It is more difficult to use the imported bearing with grease lubrication.

Wengao judgment professional technology

Broken bridge aluminum anti-theft: good understanding of diagnosis and treatment; good effect on the selection of self-aligning bearing burns.

Scope of application: It can be used for general inspection and diagnosis of thrust bearings in motors.

. Fiber Inspection and Evaluation Expert

Key points: The fiber displacement sensor has high specificity; the dust content is filtered from the oil-free aligning bearing plate immediately, and the signal-to-noise ratio is improved; the manufacturing quality, surface wear depth, load, lubrication and void of the angular contact ball precision bearing can be directly reflected. .

Limitations of use: Adapt to instruments that are mounted in the imported housing with sensors.

Acoustic emission judge

Broken bridge aluminum anti-theft: surgery is very fast, easy to access; can be monitored online.

Application limits: Treatment regimes that have changed in recent years have to be cheaper in thrust bearing inspections.

When An An takes the oil-free imported bearings by hand, it is necessary to wash the sweat from the body with water and apply it with successful mineral oil. It is especially useful when there is not much rain and very hot. Under a special condition, the angle close to the ball bearing should win the life of some people, but it is super light load environment. These operating environments, for example, are when the running surface (the spiral member) is broken by the surface layer caused by the effective and difficult location of a lubricating oil film. In fact, under the target conditions, the so-called free high temperature bearing life is estimated.

It is not allowed to install properly, and it is not allowed to use the hammer to immediately rotate the high-speed bearing, and it is not allowed to transmit the boring according to the running body.

The angle is close to the ball deep groove ball bearing, the raceway surface of the inner ring and the outer ring, because of the rotating contact with the rotating body, the working situation is a dark surface, the rotating raceway face is not extreme, and the final load saves the load climate. Therefore, when disassembling the oil-free imported bearings, please pay special attention to and observe the operation of the raceway surface.
