7.4.12. A tightness of bearings of a box of differential and adjustment of a lateral backlash

Check of a lateral backlash in gearing of gear wheels of the main transfer by adaptation A.95688/R

1 – the screw of a tightening of an arm;

2 – the indicator for check of a lateral backlash in gearing of leading and conducted gear wheels;

3 – the screw of fastening of a core of the indicator;

4 – an indicator arm;

5 – the fastening screw;

6 – a conducted gear wheel

The scheme for check of a preliminary tightness of bearings of a box of differential

D – distance between two covers of bearings of differential;

1, 2 – adjusting nuts


Preliminary tightness of bearings of a box of differential and
Adjustment of a lateral backlash in gearing of gear wheels of the main transfer – these operations carry out simultaneously by means of adaptation A.95688/R and key А.55085.

PERFORMANCE ORDER
1. Fix on картере a reducer the adaptation (fig. Check of a preliminary tightness of bearings of a box of differential by adaptation A.95688/R) screws 1 see and 6, having screwed them in apertures under bolts of fastening of lock plates of adjusting nuts.
2. On directing adaptations, displace an arm 7, before contact of the lever 5 with an external lateral surface of a cover and tighten the screw 8. Ослабте screws 1 and 3 (fig. Check of a lateral backlash in gearing of gear wheels of the main transfer by adaptation A.95688/R see) and establish an arm 4 so that the leg of the indicator 2 leant against a lateral surface of a tooth of a conducted gear wheel at tooth edge, then tighten screws 1 and 3.
3. Turning adjusting nuts, preliminary adjust a lateral backlash between teeths of leading and conducted gear wheels within 0,08–0,13 mm. A backlash check on the indicator 2 at rocking of a gear wheel 6. Thus bearings should not have a preliminary tightness. Adjusting nuts should be only in contact with bearings correctness of measurement of a preliminary tightness, otherwise, is broken.
4. Consistently and in regular intervals tighten two adjusting nuts of bearings, thus covers of bearings of differential disperse and, hence, the distance D (fig. the Scheme for check of a preliminary tightness of bearings of a box of differential see) increases. This divergence marks the indicator 9 (fig. Check of a preliminary tightness of bearings of a box of differential by adaptation A.95688/R see) on which leg the lever 5 operates. Nuts for adjustment of bearings of a box of differential tighten to distance increase D (fig. the Scheme for check of a preliminary tightness of bearings of a box of differential see) on 0,14–0,18 mm.
5. Having established an exact preliminary tightness of bearings of a box of differential, definitively check up a lateral backlash in gearing of gear wheels of the main transfer which should not change.
6. If the backlash in gearing of gear wheels is more 0,08–0,13 mm approach a conducted gear wheel to the leader; remove – if a backlash less. To keep the established preliminary tightness of bearings, move a conducted gear wheel, tightening one of adjusting nuts of bearings and weakening another on the same corner.
7. For exact performance of this operation watch the indicator 9 (fig. Check of a preliminary tightness of bearings of a box of differential by adaptation A.95688/R see) which shows size before the established preliminary tightness of bearings. After a tightening of one of nuts the indicator indication changes, as the divergence D (fig. the Scheme for check of a preliminary tightness of bearings of a box of differential see) covers and a preliminary tightness of bearings will increase. Therefore, other nut weaken until the arrow of the indicator will not return to initial position.
8. After moving of a conducted gear wheel on the indicator 2 (fig. Check of a lateral backlash in gearing of gear wheels of the main transfer by adaptation A.95688/R see) check up size of a lateral backlash. If the backlash does not correspond to norm, repeat adjustment.
9. Remove adaptation A.95688/R, establish lock plates of adjusting nuts and fix their bolts with spring washers. In spare parts deliver lock plates of two types: with one or two pads, establish plates, depending on position of a cut of a nut.
10. Adjustment and repair of knots of a reducer carry out at the stand on which it is possible to test also a reducer for noise and to check up an arrangement and the form of a stain of contact on working surfaces of teeths as it is specified in subsection 7.4.13.
