9.3.20. Check of correctness of gearing of gear wheels of the main transfer

Loading when checking correctness of gearing of gear wheels of the main transfer is provided in the way braked the conducted gear wheel by means of special adaptation (601 589 01 40 00)


 PERFORMANCE ORDER

  1. Grease couple of teeths of a koronchaty leading gear wheel of the main transfer with ink.
  2. Rotate the leading gear wheel back and forth, at the same time constraining conducted by the special holder (601 589 01 40 00).
  3. Compare received as a result of a spot of contact of teeths with the card given on illustrations below.

Normal gearing (satisfactory it is possible to consider result when spots of contact do not come for sides of working surfaces of teeths)

Shift of spots of contact to the bases of teeths, - the size of the basic landing size of the leading gear wheel is insufficient (make the corresponding adjustment and repeat check, previously having checked a gearing side play - see the Section Removal and installation of assemblies of interwheel differentials with the conducted gear wheels of the main transfers)

Shift of spots of contact to tops of teeths, - the size of the basic landing size of the leading gear wheel is excessive (make the corresponding adjustment and repeat check, previously having checked a gearing side play - see the Section Removal and installation of assemblies of interwheel differentials with the conducted gear wheels of the main transfers)

Shift of spots of contact to heels of teeths, - the size of a side play of gearing of a gear wheel is excessive (make the corresponding adjustment, - see the Section Removal and installation of assemblies of interwheel differentials with the conducted gear wheels of the main transfers, - and repeat check)

Shift of spots of contact to socks of teeths, - the size of a side play of gearing of a gear wheel is insufficient (make the corresponding adjustment, - see the Section Removal and installation of assemblies of interwheel differentials with the conducted gear wheels of the main transfers, - and repeat check)
