Intermediate bearing: half bearing broken wheel will be heavier

% - - - - - - ,, emsp; & emsp; In addition, the matching of the bearing cover and shaft tight, bearing and shaft fit too tight or too loose will also cause bearing overheating. & emsp; & emsp; When the oil change, due to the lubricating oil mixed with hard grain impurity or bearing cleaning not clean with hard grain impurities, exacerbated bearing wear and overheating, and may even damage the insulation. Installing a bearing, keep the strength of the ring and rolling body components in a correct position, fatigue spalling under the action of alternating contact stress, fatigue peeling phenomenon not only happens under the surface, but also occur on the surface. Spindle front to back to back form two bearing installation, for inner and outer ring assembly, the shaft and bearing hole with both hands thumb just can push to cooperate as appropriate. Even more than the service life of the new parts, the deformation of connecting rod calibration of piston pin installation: in front of the liner pressure equipment, should first try with the piston pin, such as can barely set into the piston pin is appropriate. Old glue contrast, after changing the point gap also have no, old top glue is annual, straight said haven't changed my own conclusion: under the front said jack underground block brick, must. - NR— — With - Zinc, and with a snap ring, in the use of set set of circumstances, can be used with the hook spanner or impact wrench locking sleeve nut, - ZNR— — With - Zinc, and with a snap ring, hydraulic nut can put the tapered hole bearing installed on the cone diameter of axle, tight sleeve, sleeve back. Rolling body have irregular sound, have individual roller bearing, need to change, the motor on time is too long, lubricating grease metamorphism, harden; A new lubricating grease should be replaced. For bearing clearance can be adjusted, because of its axial gap and radial gap there is a direct proportion relationship between, so the installation is adjust axial clearance can be obtained as long as the radial clearance, but they are used in pairs of ( In the ends of the shaft or side) And, therefore, you just need to adjust only bearing axial clearance. Two kind of shape tolerance is: single radial plane, bearing (inside diameter ds） And the outside diameter ( Ds） The amount of change, Vdp, Vdp) ； The bearing inner ring ( dmp） And the outside diameter ( Dmp） The amount of change, Vdp, Vdp) 。 Tooling drawings and machining precision of surveying and mapping is confirmed to repair the size of the key factors, and the equipment running status and use of the late effect of carbon nanotubes is by sauvy comprehensive mechanical properties of polymer materials, polymer materials in the process of using carbon nanotubes will not produce metal fatigue wear and tear on the premise of normal equipment maintenance, the service life of repaired even higher than the service life of the new parts. If a ring should be full inspection after pickling, picking products, serious cannot repair or repair the unqualified should be scrapped, there is no grinding ring into the assembly process.
