Bearing the nu: bearing clearance 1 group 2 what do you mean

Bearing raceway rust, in the case of problems, and equipment and construction are important, that whet knife and wood industry, the reason is the right choice, steel ball, roll wear ( Grinding is unqualified or products are bruised) , the image for the company to film, rustling figure will investigate main use: automotive steering pin, machine tool spindle. Traditional repair technology for bearing wear, traditional online technology repair scheme has the following categories: set non-standard sets of pitting, direct bearing assembly replaced with non-standard sets of Mosaic non-standard sets, must logoff machining processing, make it difficult to implement for dust removal fan and other important equipment downtime of production for a long time to repair, the enterprise will not adopt this technology. Improper assembly clearance adjustment: needle roller bearing clearance is divided into radial clearance and axial clearance, its function is to protect the normal operation of the rolling body and lubrication and compensating thermal elongation. Main causes include: early to open the bearing packing before use, cause pollution; When installation work environment is not clean, cause pollution; Bearing of the working environment is not clean, working medium pollution, etc. When the monitor to the import of outer spherical bearing low frequency vibration is very large, in addition, but pay attention to in the practical skills, the actual found that many of the vibration is not overweight, and bearing failure. Generator bearing front because of its high load, high speed, is to use a large single row deep groove ball bearings and double row deep groove ball bearing, the back-end using single row deep groove ball bearings. Spherical raceway sphericalraceway raceway for the ball on the surface of the part, ( Ditch) Shoulder ( 槽) Shoulder channel ( Roll) The side of the road. Fault has the following several ways: as a vibrator under heavy load start suddenly shut down due to production or other equipment failure, makes the screen box full of mineral aggregate, vibrator, such as in the case of heavy load again started easily to universal coupling vibrator and other damaged parts. Quantity is too large, here noted: preload oil supply deficiency can lead to increased wear and temperature rise, cause excessive wear and/or premature failure of the bearing and damage. Second, check the bearing have chewed and wear; Check the bearing inner and outer ring, rolling body, maintains its surface finish and presence of cracks, defects such as rust, peeling, indentation, overheating, excessive measuring bearing clearance; Look for wear, pit shaft sleeve, peeling, if there is more than a new bearing should be replaced. Drying cylinder bearing a repair process comprehensive comparison for different papermaking enterprises dryer for bearing wear repair methods mainly include: spray, brush plating, welding, the blue polymer composite materials to repair. Sauvy engineer measuring bearing a wear depth bearing a online repair technology of sauvy technology advantage analysis: sauvy industrial carbon nanometer polymer repair technology is the use of carbon nanotubes unique mechanical properties of polymer materials and corresponding repair process online repair axial of wear and tear.
