ADJUSTMENT DIFFERENTIAL AND BEARING CLEARANCE SIDE MAIN TRANSMISSION
1.Install differential in the housing and screw jacks
bearing caps. With the help of an indicator as set out in the rack,
check the runout end of the driven gear. Permissible runout 0.08 mm.
If its value exceeds the allowable, remove the cause of the beats
(Tighten the bolts, clean up the burrs or nicks, if they
found during the inspection). If the heartbeat does not decrease, change
2.Proverenny differential set in the socket housing with a small
barely perceptible lateral clearance between the teeth of the driving and driven
gears, screw the adjusting nut (closer to the bearings
differential), the bearing caps and tighten the bolt caps.
3.Zavernite adjusting nut with a special key
(Fig. 122) of the driven gear to obtain lateral
0.08-0.10 mm gap after tightening the bolts bearing cap
differential on the same side. In this case the opposite
adjusting nut should not touch the outer ring of the bearing.
Backlash in the meshing of the teeth is measured by the indicator,
enshrined in the rack, which should be stable and should
installed so that the indicator pin was located in the
radial direction to the tooth surface (see Fig. 111).
4.After that tighten the adjusting nut opposite
so much so that after tightening all the bolts caps prdshipnikov
torque wrench (tightening torque 6,8-7,5 kgf-m) side
the gap was equal to 0.15-0.17 mm for the same tooth. The difference
between the highest and lowest clearances at turning the
driven gear on a turnover of noxtexceeding 0.08 mm
(For details see Sec. "Main features and requirements for the collected
the main program ").
5.After adjust backlash, install and tighten
adjusting nut bolt retainers. Stops place depending
the position of the projections on the adjusting nut.
6.Zastoporite pinion nut by squeezing the top
cylindrical part of the nut opposite the slot in the threaded
the end of the pinion.
When installing the main gear on the beam asymmetrically located
his mouth should be at the bottom. Between the flange of the main housing
transmission and flange beams need to put a cardboard shim
0.5 mm thick. Bolts that attach the main gear,
for better sealing of threaded holes is desirable to dip
in the paint of the aluminum powder.
