Correct Maintenance And Use Of Timken Bearings

Maintenance And Use 

1. Timken bearing installation

Whether Timken bearing is And Use installed correctly affects the accuracy, service life and performance.

Therefore, the design and And Use assembly department should fully study the installation of Timken bearing. It is hoped that the installation will be carried out according to the operating standards. Items of operating standards are usually as follows:

(1) Clean the bearing and its related parts

(2) Check the size and finish machining of related parts

(3) Installation

(4) Inspection after bearing installation

(5) Supply lubricant

2. Timken bearing alignment and alignment

After Timken bearing is installed, if alignment is not carefully carried out, the alignment may cause the And Use bearing to suffer additional load, friction and vibration.

These may accelerate fatigue and reduce the service life of bearings, and may damage the service life of other machine parts. In And Use addition, increased vibration and friction may greatly increase energy consumption and the risk of premature failure.

Correct Maintenance And Use Of Timken Bearings

3. Timken bearing basic condition monitoring

During use, the basic external conditions of Timken bearing And Use operation should be monitored frequently, such as temperature, vibration and noise measurement.

These regular inspections will identify potential problems as soon as possible, prevent And Use unexpected machine stoppage, realize the production plan and improve the productivity and efficiency of the plant.

4. Re lubrication of Timken bearings

During operation, the bearing requires correct re lubrication to perfect its performance. The And Use methods of bearing lubrication are divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, choose the lubrication method suitable for the use conditions and purposes.

If only lubrication is considered, the lubricity of oil lubrication is dominant. However, grease And Use lubrication has the advantage of simplifying the structure around the bearing.

5. Timken bearing unloading

When Timken bearing will reach its final service life, it should be replaced.

Although Timken bearings can no longer be used, correctly removing the original bearings and replacing new bearings in time can play a good role in prolonging the service life of new bearings.

First, the proper removal method and the use of tools will help prevent damage to other machine components;

Second, improperly removed technology may cause harm to the operator.

Low quenching temperature or poor cooling will produce troostite structure exceeding the standard in the microstructure, which is called underheated structure. It will reduce the hardness and sharply reduce the wear resistance, and affect the service life of fag imported bearings

The crack formed by internal stress during quenching and cooling of fag imported bearing parts is called quenching crack. The reasons for this kind of crack are as follows: because the quenching heating temperature is too high or the cooling is too urgent,

the structural stress when the thermal stress and metal mass volume change is greater than the fracture strength of the steel; The original defects on the working surface (such as surface micro cracks or scratches) or internal defects of steel (such as slag inclusion, serious non-metallic inclusions, white spots,

shrinkage cavity residue, etc.) form stress concentration during quenching; Severe surface decarburization and carbide segregation; The tempering of parts after quenching is insufficient or not tempered in time;

Excessive cold punching stress, forging folding, deep turning tool marks, sharp edges and corners of oil groove caused by the previous process. In a word, the cause of quenching crack may be one or more of the above factors, and the existence of internal stress is the main cause of quenching crack.

The quenching crack is deep and slender, the fracture is straight, and the fracture surface has no oxidation color. It is often a longitudinal straight crack or annular crack on the fag imported bearing ring;

The shape of fag imported bearing steel ball can be S-shaped, T-shaped or ring-shaped. The microstructure characteristic of quenching crack is that there is no decarburization on both sides of the crack, which is obviously different from forging crack and material crack.
