How to adjust small eight main reducer gear bearing clearance?

How to adjust small eight main reducer gear bearing clearance? 2020 - 10 - 6 small eight gear bearing in operation is normal or not, depends on the bearing inner clearance, clearance outsiders can lead to bearing ablation, makes all the transmission parts to stop; Clearance will lead to bearing loose kuang, runout gear axis, so that affect the normal of a pair of size of eight gear meshing and transmission. To this end, small eight gear bearing clearance adjustment must be appropriate, can have the effect of bearing should be. Small adjustments in the horoscope gear bearing before, must understand its characteristics, in order to adjust the gap to reliable: ( 1) This is tapered roller bearing rod bearing, taper is small, the two sets of bearing can withstand small eight gear after the loading of axial, radial and oblique force, so the bearing adjustment gaskets, and fastening nut bushing is to determine the reliability of the bearing main parts. ( 2) Bearing clearance allowance and allowance for different engine bearings. Engine bearings are set aside as lubricating oil channels and bearing clearance room for expansion, and otherwise make bearing loose kuang, guarantee the stability of lubricating oil pressure. Although small eight gear bearing tapered roll bar lubricating oil are all around, but the lubricating oil pressure, two bearing inner expansion amount is larger, so the bearing clearance will grow larger. ( 3) In a car with overdrive, the bearing rotating speed often exceed the highest engine speed. Although small eight gear bearing in type _L and differential bearing the same, but the differential bearing speed only 1/5 ~ 1/10 for small eight gear bearing, high-speed rotation makes small eight gear bearing friction heat expansion, so the bearing clearance allowance should be larger. Before tuning small iron eight gear bearing clearance, whether repair or warranty vehicles, shall be uniformly after removal of single small eight gear bearing shell Hugh adjust bearing clearance, not allowed to take gear reducer shell with the size of a set of eight and at the same time, it can avoid the misadjustment due to meshing gear mutual restraint. Small eight gears, bearings, bearing a coat or bearing shell, should change new should be in new, pressing and assembling. Bearing inside and outside are interference conditions, do not allow the assembly after the loose phenomenon, this can avoid bearing inside and outside a hole and shaft neck, seat and thrust surface caused by poor contact misadjustment.
