Figure 3.16.4 – Composition of the FDA with two-stage spur planetary wheel gear
groups of final drives
Drive gear of the main gear 36 (Figure 3.16.4) is installed in cage 29 on two bevel
roller bearings. Preload in bearings is adjusted by means of adjusting washers 30, whereaf-
ter tightening with nut 33 should be carried out. Driven gear 19 is mounted on splines and
centering band of the body of differential 18 and is locked by nut 20 against axial movement.
Adjustment of meshing of the main gear is provided by shims 28, 15 installed between
flange of the drive gear cage and the FDA body, as well as between left and right tube and
the FDA body accordingly. Before adjustment of meshing adjustment of differential bearings
42 is carried out, which is done by shims 15.
Left 14 and right tube 22 connected to FDA body 21 by bolts form axle beam. The
FDA body is provided with breather 17, maintaining normal pressure in the cavity of the axle
beam and main gear.
