Deep groove ball bearing clearance parsing

Deep groove ball bearing clearance analytical source: bearing | last updated: - 2020 04 - 02 deep groove ball bearing clearance parsing the radial clearance of the bearing is divided again the original clearance, installation clearance and work clearance. Usually, bearing the original beginning radial clearance is greater than the bearing clearance at work. Clearance is an important technological parameters of the bearing, it directly affects the bearing load distribution, the service life of the vibration and noise, friction, and technical performance of movement precision machinery. Strictly speaking, the bearing dynamic load rating is varies with the size of the clearance. The rated load (listed in the product samples C and C0) Is the work clearance is zero load value. Clearance is too large, will cause the bearing load decreases, and the rolling contact stress increases, the movement precision of bearing, vibration and noise increased, the service life of bearing shorten: such as clearance is too small, can cause fever, even lead to bearing 'killed' phenomenon occurred during operation. Therefore, according to the type of bearing and working conditions to select different levels of bearing clearance is very important. Standard deep groove ball bearing with C2, standard ( CN） Internal clearance level, C3, C4 and C5, all consistent with GB4604. Deep groove ball bearing processing form and pay attention to the problem of deep groove ball bearing parts processing form is as follows: 1, multistep process: general bearing production need 20 ~ 40 working procedure, much more than 70. 2. Processing: bearing parts of the surface of the work are rotary forming surface, suitable for molding in processing. 3, precision machining: most of the surface to bearing parts after grinding, grinding size and geometric accuracy in microns. Pay attention to the problem of deep groove ball bearing, bearing load during operation is too small, can produce sliding between the ball and raceway, be the cause of the scratch. Especially the big ball and cage weight large deep groove ball bearings have this tendency. In use is expected to have the load is too small, when selecting a bearing should contact related people in time! ”
