Rolling mill bearingtechnology, is a systems engineering technology, and also the multidisciplinary field of comprehensive engineering technology, its development speed and ability to support the formation of a reflection of the pace of development of Chinese industry and the level achieved. Hereby briefly discusses several key aspects from running technology, manufacturing technology, testing technology, theoretical research, product development, complete sets of capacity.
Development of oil film bearing main parts, began in the late 1950s,aviation bearing in the case of a no pattern, nor information, three non-proprietary equipment carried. Development of oil film bearing the main parts, and easy, from material selection, process route, processing methods to special tooling design and manufacturing has a set of working procedures. From the choice of materials, taking into account the drogue and friction material pairing, drogue forging process of combining steel bushing sleeve and friction materials, steel sleeve process
Precision bearings according to ISO grading standards are divided into: P0, P6, P5, P4, P2. Rank higher in turn, where P0 is the general accuracy, other grades are precision level. Of course, different classification standards, different types of bearings, their classification method somewhat different, but the meaning is to the. The use of performance requirements of precision bearings rotating body with high runout accuracy, high-speed rotation and small changes in friction and friction.
