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 install special devices (cores) in openings And yes In selectors and turn selectors so that to increase a gap. After that turn 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. Measurement of a gap in the selector


Use the probe to measure a gap in 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 a main shaft:
choose the thinnest admissible laying from the table to receive a standard gap.
Standard gap: 0–0,05 mm.
Example:
value of measurement of the probe – 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 of the probe: 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 dynamometer key


Install special adaptation and a dynamometer or a dynamometer key (fig. 3.62).

Fig. 3.63. Adjustment of a gap of the selector


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

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

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

Fig. 3.64. Measurement of a gap in the selector for differential


Use the probe for measurement of a gap 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 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 special adaptation.
Remove selectors, a main shaft and differential.
Remove holders of bearings.

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


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

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

ATTENTION
Use the adjusting laying chosen at adjustment of a preliminary tightness in the bearing.
