Mind of the master: the bearing of the paver's scraper drive shaft
Bearing (Bearing) is one of the most important parts in modern mechanical equipment. Its main function is to support the mechanical revolving body, reduce the friction coefficient during its movement and ensure its rotary precision.
Mind of the master: the bearing of the paver's scraper drive shaft
Relative to large machinery, bearing is a very small part, but it plays an important role. In engineering machinery, bearing parts are more essential. Paver drive shaft bearing is a common wearing part. Therefore, finding the proper paver bearing is the main concern of machine owners.
A mechanical engineering management of SKF paver scraper drive shaft bearing from the SKF group, the company is bearing technology and manufacturing leader. Today, SKF still marks the highest quality rolling bearing.
For testing the durability of its own machine bearings or business bearings, we can identify the following points:
1, a variety of mechanical injuries, such as scratch, scratch, crush, bruise, will cause the bearing installation, causing partial load and stress concentration, decrease the rotation accuracy and service life.
2, rust, black and Ma, the latter two are easy to store water and dirt of the defects, most likely to develop into rust. Corrosion is the source of bad installation, early wear and fatigue, and serious corrosion will cause the bearing to be scrapped.
3, all kinds of cracks, cracks such as raw materials, heat treatment, forging crack crack and grinding cracks, these cracks in the bearing in operation, will become the source of stress concentration and the rapid expansion, resulting in bearing rupture, and has a great influence on the bearing life and work safety. In fact, for bearing of important use, the bearing plant has 100% magnetic or ray inspection inspection of its components.
4, peel and fold, the two defects are not bonded with the matrix metal, and there are decarburization or carbon depletion around them. Materials are easy to caving, concave or wear, which is very unfavorable for bearing life and accuracy.
5, the riveting or welding quality of the cage. Mainly observe whether the rivet head is partial, skew, slack, lack of meat or double eyelids, the location of welding is correct, whether the solder joint is too large or too small, whether it is not firmly welded or overwelded to cause stuck roller phenomenon.
The above items are the key parts that we examine in the imported bearings of SKF. Besides those parts above, besides typing, poor quality, such as blurred or damaged handwriting, we should consider that the inferior products can not be accepted by the serious ones.
The scraper drive shaft bearing of SKF paver is built strictly according to the professional standard. The quality and service quality of the product can be completely assured.
