Introduction to bearing production and processing

2019 - introduction to bearing production and processing 08 - 11 / jian-lei zhang about bearing, everybody is not strange, but there may be some friends don't know. In simple terms, is anything that could turn the mechanical equipment is inseparable from the bearing. Its use is very broad, big to the defense industry, aerospace, mining metallurgy, small to various vehicles, ships, machinery and equipment, and so on. It is defined as: used to supporting shaft, drive shaft rotation, and reduce the friction of machine parts. Here I want to give you simply introduce bearing production process and processing technology, let everyone know about bearing simply, too. A, the classification of bearing bearing points of two kinds of rolling bearing and sliding bearing. Because here we only said rolling bearing, sliding bearing is rare, common are almost rolling bearing. Rolling bearing is divided into the ball bearing and roller bearing ( Is is ball is ball bearings, roller roller of roller is for roller bearing) , from which can be divided into the centripetal force direction and thrust bearing two kinds. To the heart of the radial force is big, axial force and the thrust is big. From its level of accuracy and can be divided into P0, P5, P6, P2 and P4, prioritize is lowest P0 precision, P2 highest precision. From its material and can be divided into ordinary bearing steel, high temperature resistant, antimagnetic, non-corrosive, carburizing and etc. And it's appearance can be divided into the miniature size, small, medium and large, super large and large. All in all, the classification of bearing, many natural its type and model is as many as thousands of kinds. Second, bearing production and processing process of each set of bearings are through dozens of working procedure from raw material to finished product, seemingly simple, actually is very complex. Bearing structure by the outer ring, inner ring, cage and rolling body ( Ball or roller) Composition. Bearing parts to go through the material of forging blank - annealing - turning - soft grinding - quenching - tempering - fine grinding in the early - end mill - set - assembly - type - cleaning - rust - packing. The grinder process more machine tools to complete. Plane, inside diameter, outside diameter, raceway, guard, etc. , are quite complex. Precision tolerance control in every millimeter commonly within a few parts per thousand. Other high precision bearing pass strong heat and strong cold treatment, nondestructive flaw detection, to ensure that finished products in various environments using deformation, wear resistance. Above is my in the bearing industry more than 20 years have about the whole process of bearing production and processing, to share with you. After see hope friends can have a preliminary understanding. With the constant improvement of the national economy and modern science and technology, production and processing technology of bearing could also be improved, we will explore improvements in the production practice, as far as possible, live and learn, to learn and practical!
