3.2.7.6. Elimination of gaps of primary, secondary shaft and shaft of differential of a case of the main transfer

Fig. 3.59. Elimination of gaps before installation of bearings


For installation of bearings establish special adaptations (cores) in openings And and In selectors and turn selectors so that to increase a gap. After that turn the special adaptation in the opposite direction before elimination of gaps (fig. 3.59).

Fig. 3.60. Expansion of selectors manually


Manually expand selectors against the stop (fig. 3.60).

Fig. 3.61. Gap measurement in the selector


Use щуп to measure a gap in the special adaptation (selector) (fig. 3.61).

ATTENTION
Measure a gap on all circle of the selector.
Remember the maximum value and choose laying as follows.

Adjusting laying of primary shaft:
choose the thinnest admissible laying from the table to receive a standard gap.
Standard gap: 0–0,05 mm.
Example:
value of measurement щупа – 0,57 mm;
range of thickness of laying: (0,57 mm – 0,05 mm) – (0,57 mm – 0 mm) = 0,52 mm – 0,57 mm;
laying: 0,55 mm.

Adjusting laying of a secondary shaft:
choose the thinnest admissible adjusting laying of a secondary shaft from the table to receive a standard gap.
Tightness size: 0,03–0,08 mm.
Example:
value of measurement щупа: 0,57 mm;
range of thickness of laying: (0,57 mm + 0,03 mm) – (0,57 mm + + 0,08 mm) = 0,60 mm – 0,65 mm;
laying: 0,60 mm.

Fig. 3.62. Installation of a dinamometrichesky key


Establish the special adaptation and a dynamometer or a dinamometrichesky key (fig. 3.62).

Fig. 3.63. Adjustment of a gap of the selector


Adjust a gap of the special adaptation (selector) to receive a certain value preliminary a loading/dynamometer (fig. 3.63).

NOTE
Consider value of preliminary loading when the differential starts to turn.
Measure several times and calculate average value.

Preliminary loading: 0,5 N · m.
Value on a dynamometer: 5 N.

Fig. 3.64. Gap measurement in the selector for differential


Use щуп for gap measurement in the selector for differential (fig. 3.64).
Add 0,15 mm to the measured gap and choose a combination of laying which gives value the closest to the measured.
Example: 0,32 mm + 0,15 mm = 0,47 mm.
The next laying (on the thick party): 0,47 mm – 0,50 mm
Remove a case of the main transfer and the special adaptation.
Remove selectors, primary shaft and differential.
Remove holders of bearings.

Fig. 3.65. Installation of a holder of the bearing of primary shaft


Establish adjusting laying (ки) and a holder of the bearing of primary shaft, using a suitable pipe (fig. 3.65).

ATTENTION
Use adjusting laying (ки), chosen at adjustment of a preliminary tightness in the bearing.


Fig. 3.66. Installation of a holder of the bearing of a shaft of differential


Establish adjusting laying (ки) and a holder of the bearing of a shaft of differential, using a suitable pipe (fig. 3.66).

ATTENTION
Use adjusting laying (ки), chosen at adjustment of a preliminary tightness in the bearing.
