Bearing elements to improve the quality of production

Bearing is the most important parts of machinery, the use of quality is the first choice, bearing in the process of production in order to improve the quality of the bearing and the bearing network according to the understanding of tell people mainly from the five aspects to improve the bearing quality requirements in the production process. 1, motor assembly site to keep clean, bearings coated with grease, there is no dust float in the sky. And bearing with after the parts have to pass strict inspection before assembly, every tiny link should not be neglected. Shoulder of shaft and bearing fit, for example, if you are clear root fillet, operation, easy to produce stress concentration and the shaft twist off here; If the rounded corners is too large, or not in place when grinding, fitted with the amount of interference when bearing inner ring is super bad, or bearing can not reach the designated position, all these are the bane of bearing early failure. 2, dynamic balance quality are the crucial factors affecting the service life of bearing. The higher the motor, the greater the speed, and the higher requirements about the quality of the dynamic balancing. 3, related to the bearing parts - — Stand, end cover, rotor, bearing inner and outer cover of the coaxial degree is better, and to ensure in the running of motor don't damaged due to deformation of the parts. Size larger components, such as frame, end cover must be aging treatment. 4, related to the bearing parts machining accuracy to improve. Because of the high machining precision of the bearing itself, and bearings and related parts and components, a tiny amount of interference can cause the damage of the bearing. Practice verification, the use of nc machine tools with the size of the cutting tool machining bearing chamber tolerance zone can be controlled in the range of 0, 02 mm or so. Cooperate with bearing inner and outer ring of roughness also should improve as far as possible, otherwise, after a lot of dismantling the golden processing 'knife peak' wear off, the original design fit tolerance also changed. 5, grease in moderation, or bearing will fever. If the environment temperature is higher than 40 ℃, should choose high penetration of grease. On the other hand, should use penetration is low or the special grease. Bearing used in the event of a failure is inevitable, if improve the quality of bearing, is to see how the use of the bearing, we also can through the above five aspects when choosing bearing on understanding, refer to how the quality of bearing. 【 Warm prompt. 【 The bearing network] Some information from the Internet, and strive to secure timely, accurate, aims to deliver more information, does not represent our views to its approval or responsibility for their authenticity.
