Failure Prediction And Prevention Of Iko Outer Spherical Bearing

Iko Outer Spherical Bearing

1. Ways to predict and prevent early bearing failure

In important mechanical equipment, the service life of spherical bearings is an important index. It is very necessary to understand and Iko Outer Spherical Bearing master the working state of IKO bearings, predict and prevent early failure of bearings. There are usually the following main ways.

(1) Adopt advanced technology to improve the service life and reliability of bearings. Including structural optimization design, reform of processing technology, selection and refinement of materials, lubrication with high Iko Outer Spherical Bearing efficiency and cleanliness, fine assembly and installation, etc.

(2) Strengthen the quality inspection and supervision of bearing products to ensure that the quality of outer spherical bearing products meets Iko Outer Spherical Bearing relevant standards or design requirements.

(3) Strengthen the monitoring and diagnosis of IKO bearing working state, find abnormalities as soon as possible, and take preventive measures to prevent major losses that may be caused by sudden accidents.

2. Fault diagnosis and detection system

Modern IKO bearing fault diagnosis technology is associated with Iko Outer Spherical Bearing precise test system and monitoring means. At present, there are several mature detection systems in practical application.

(1) Bearing pulse side vibration device

After bearing fatigue wear (or fatigue peeling), vibration is generated, and the receiver converts the mechanical pulse signal into electrical signal and amplifies it. When the number of pulses exceeds the normal range and reaches a sudden change, an alarm shall be given immediately and the outer spherical bearing shall be stopped.

(2) Bearing temperature alarm device

Poor lubrication, surface wear or fatigue of IKO bearing will make the surface heat. When the heat Iko Outer Spherical Bearing reaches a certain limit temperature, the alarm will be given and the bearing will stop running.

(3) Regularly detect the current state of the bearing in operation, Iko Outer Spherical Bearing find or monitor the existing defects and development trend.

(4) Ferrography diagnosis

Regularly take the lubricating grease samples of the working outer spherical bearing, and use the Ferrograph to detect the number, Iko Outer Spherical Bearing size and shape characteristics of the wear particles, which can find the degree of fatigue and wear and the signs of IKO bearing failure.

How To Correctly Judge The Damage Fault Maintenance Of Ina High Temperature Bearing

When mixing two incompatible oils, never mix incompatible oils. Usually, the consistency will become soft, and then it will be damaged due to the loss of grease. If you don’t know what kind of grease you used for fag bearing, first remove all the original grease, and then add a kind of grease for lubrication.

In the process of using linear bearings, we often encounter such situations. How these situations are formed and how to solve them v when they are formed have always been a headache for technicians in major enterprises,

The following is a detailed introduction to the causes and solutions of overheating of fag bearing in use: the instantaneous high temperature in the grinding area can make the surface heated to a certain depth (10 ~ 100nm) higher than the tempering heating temperature of the workpiece.

When the austenitizing temperature is not reached, with the increase of the heating temperature, the surface layer by layer will produce the microstructure transformation Iko Outer Spherical Bearing of re tempering or high-temperature tempering corresponding to the heating temperature,

and the hardness will also decrease. The higher the heating temperature, the more severe the decrease of hardness.

In grinding, the contact area between grinding wheel and workpiece consumes a lot of energy and generates a lot of grinding heat, resulting in local instantaneous high temperature in the grinding area. It can be found that the instantaneous temperature in the grinding area can be as high as 1000 ~ 1500 ℃ in 0.1 ~ 0.001ms.

Such instantaneous high temperature is enough to make the surface layer at a certain depth of the working surface produce high-temperature oxidation, amorphous structure, high-temperature tempering, secondary quenching, and even burn cracking.

Under the action of instantaneous high temperature, the steel surface reacts with oxygen in the air to form an extremely thin (20 ~ 30nm) thin layer of iron oxide.

It should be noted that there is a corresponding relationship between the thickness of oxide layer and the total thickness of surface grinding metamorphic layer. This shows that the thickness of oxide layer is directly related to the grinding process and is an important symbol of grinding quality.

The grease used in fag bearings has rust resistance. The antirust performance mainly depends on the solubility of the grease. The grease formed by different viscosity and different data has different levels of anti volume and antirust performance.

Generally speaking, the grease with high viscosity and poor fat solubility has better waterproof performance. Even if the grease is filled with water in the linear bearing cavity, it can form a layer of oil film on the surface of steel. Due to the low rotation speed of bicycles, the choice of grease can be relatively high in viscosity,

but it has strong water resistance. Because bicycles often deal with water in car washing, rainy days and off-road, which makes the water resistance very important. Even slightly viscous grease will not affect the smoothness under low rotation.

Once oxidation damage is formed on the surface, Then the whole peeling process and aging process will intensify rapidly.
