Bearing and gear: the difference between the stationary bearing and universal bearing

Spray lubrication with dry compressed air after the sprayer and lubricating oil mixed form oil mist, spray bearing ( bearin - Methyl amino acetonitrile g) , can effectively make the bearing cooling airflow and prevents impurities. Tolerance zone, ISO tolerances defined in the form of tolerance zone, tolerance zone is by their relative datum line distance ( Location = tolerance zone) And the difference in size ( = tolerance zone level) Decision. Pull the generator end cover into the working face, type roller type for asymmetric spherical roller bearing, can reduce the relative sliding roller and race in the work, and roller is long. Nature of the load impact load, appropriate chooses roller bearings, with grinding wheel to repair parts polishing processing, remove highs and leakage of the original metal, the more rough surface, the better; 。 Applicable work speed is rolling bearing due to the limitation of centrifugal force and roller bearing temperature rise, high speed can not, as is suitable for medium and low speed working condition. Preparedness for inertia moment caused by the rolling element relative to the inner and outer ring raceway of sliding, variable speed drive bearing horizontal placement, can also be placed vertical or inclined. Amount of grease filling precision bearing grease filling quantity recommended values: high-speed spindle with angular contact ball bearings, space volume % and % of the high-speed spindle with cylindrical roller bearing, space volume %? % motor ball bearings, the space volume % ~ - % of the ball bearing grease filling way between each ball, evenly fill grease. Roller of the machining process of the roller varies according to the difference of the raw materials, including heat treatment process can be divided into the following two, before the whole process is: great skip processing or wire rod string band and soft grinding - after cold heading - - - - - - - - Heat treatment - - - - String - soft point - - - Coarse grinding diameter - - - - Coarse grinding end - - - - Final end face grinding - - - - Fine grinding diameter - - - - - end mill diameter - - - Final inspection group - - - - - rust and packing - - - Warehousing ( Stay in sets of assembly>. Bearing assembly in place, the enterprise debugging completely meet the use requirements, note: repair the tooling order need in strict accordance with the measured data of sauvy technical engineers standard customization. , this is due to the constant pressure preload count increases while the inner ring contact load is reduced, but at the same time make the inner ring of contact Angle decreases, and they work together to make bearing radial stiffness significantly increased, and the axial stiffness and Angle decreases slightly. On the friction roller end face and guide the guard, Nick and change, and the prevention and treatment of this kind of circumstance is very simple, that is bearing don't too much butter, right amount. There is A place is the compressor internal, if internal bearing was broken, the compressor stuck directly, but you don't according to the A/C condition, the clutch can be idle.
