6. ADJUSTMENT DRIVE PINION DISTANCE
To obtain the proper tooth flank contact,
adjust the axial position of the drive pinion
with the thickness of the adjustment disk.
The necessary thickness of the adjustment
disk for first time assembly can be obtained
by measurement(see calculation example).
The final thickness of the adjustment disk can
be fixed during the checking of gear meshing
at the assembled drive assembly(see page
"Adjustment of gear meshing of gleason
gears").
*)
A = Set value for correct pinion support. This dimension is written on the end face of the pinion in
millimeter. It indicates the deviation from the theoretic distance(setpoint dimension).
**)
B = Measured width do the taper roller bearing.
Calculation example to ascertain the thickness S from the adjustment disk
A = +0.10 : B = 37.95
S =
3.00mm(theorem)
→ B = 0.05mm smaller than B theorem
+ 0.05mm
= 3.05mm
- 0.10mm → drive pinion value A
2.95mm → necessary thickness of the adjustment disk
=
=
Fit corresponding disk and outer rigs of the taper roller bearings.
*)
Hint : If value A is positive(f.e. +0.1) the adjustment disk has to be 0.1mm thinner than theorem S.
If value A is negative(f.e. -0.1) the adjustment disk has to be 0.1mm thicker than theorem S.
**)
Hint : If measure B is positive(f.e. 38.05) the adjustment disk has to be 0.05mm thinner than theorem S.
If measure B is negative(f.e. 37.95) the adjustment disk has to be 0.05mm thicker than theorem S.
