FANAD 6203 is using a wide range of mechanical industry, demanding a matching parts and components, known as mechanical joints. Bearing simple and complex internal structure, its development not only need to consider the material, manufacturing technology and application conditions, but also involving the mass calculation and analysis. Current bearing industry 2 dcad mostly use the traditional design method, based on the calculation of the Excel, the structure of the pure 3 d tool design and analysis, and adopts simple bearing design system for research and development, therefore the domestic bearing industry generally have low r&d and innovation, product reliability and life can not meet the requirement of the current technologies, such as problems, also make the production capacity is low at the same time, enterprise production unable to achieve economies of scale. And imports bearing ring processing imported bearing inner ring and outer ring processing varies according to the difference of the raw materials or blank forms, including car before machining process can be divided into the following three, the whole process is: the bar stock or tube (some bar need to the forging, annealing, normalizing) - car processing, heat treatment, grinding, grinding or polishing parts - final inspection - rust - storage - (it can be set of assembly) Also, replace the bearing of the most common method has two kinds: one kind is with acetylene oxygen bearing direct heating; The other is for small bearings used in oil heating, thermal, expand the bearing inner diameter, so that assembly. These methods in the long term has been widely used in equipment maintenance, basic meet and solve the problem of the bearing assembly in equipment maintenance. With equipment, technology level of ascension, wazhou and tianma domestic enterprises import substitution has begun by the yaw and the variable plasma bearing expands to the bearing of main shaft bearing and gear box.
