【 Jiaxing bearing 】 About bearing a matter of choice

Jiaxing bearing group sales co. , LTD is bearing factory in jiaxing at the center of the province set up a spot directly, inventory sufficient, specializing in HRB bearing brand, service users, professional engineer to solve technical problems for the user, today for you to introduce about bearing a matter of choice. Using rolling bearing all kinds of machinery, instruments, such as market performance has become increasingly strict, for bearing the required conditions, the performance is also increasingly diverse. In order to from a large number of structure, size, choose the most suitable bearing, need study from various angles. When choosing bearing, generally, considered as a shafting bearing arrangement, installation, remove the difficulty level of, bearing, size allowed by the space and marketability of bearing, roughly defines the structure of the bearing. Secondly, comparative study on various mechanical design life of the bearing and the bearing of a variety of different endurance limit bearing has to be decided. When choosing bearing, tend to be only consider the fatigue life of bearing, the aging by grease and grease, wear life, noise, etc. Also need to be fully research. Furthermore, according to different purposes, it is necessary to select precision, clearance, cage structure, grease, etc. , as a special design of the bearing. However, choosing bearing no certain order, rules, consideration should be given priority is to bearing the required conditions, performance, most related matters, especially the actual. Considerations when choosing a bearing, bearing the required conditions, performance, use conditions, environmental conditions, bearing installation dimensions of the items, bearing the allowed space, load size and direction of vibration, shock, the limit speed of rotation speed, bearing, inner ring and outer ring tilt, fixed and bearing with the axial direction, loading and unloading easy, noise, torque, rigidity, the marketability and economy. The basic order of bearing selection and rules: 1. Decided to use mechanical and bearing structure, arrangement: design life equivalent dynamic load or equivalent static load rotating speed axial load is permitted 'static load coefficient ( Under the condition of cylindrical roller bearing) 2. Decided to bearing size: the precision of the rotating pendulum high-speed rotating torque change 3. Decided to bearing precision grade: cooperate with the difference in temperature between inner ring and outer ring of rotating speed of inner ring and outer ring tilt preloading volume 4. Decisions ( Internal) Clearance: rotation speed noise temperature 5. Decided to keep the shape, material: using temperature rotate speed lubricating maintenance, repair 6 way seal. Decided to lubrication, lubricants, sealing method: loading and unloading order job card mold related to installation size 7. Decision related to the installation size 8. Determine 9 handling methods.
