Hi all,
Any input welcome
I'm trying to mate my crownwheel and pinion together and would appreicate a little adivce. The CW and P are both new, brought as a set, but not sure if they are were "matched". Anyway I've tried to get the markings as shown in the Woodrow manual but I'm not sure I fully understand what I'm doing. I've attached link to a video that shows the contact patch. I've also attached a photo with the contact patch marked in pink (the blue didn't come up well in the photo). I think the contact patch is too close to the end of the tooth and needs to be moved back slightly closer to the base of the pinion.
My interpretation of the sketches in Woodrow and the comments around adjustments is that this contact patch shows that the pinion needs to moved nearer to the crownwheel by removing shims. Is this correct or am I getting in 180 degrees wrong?
If it is correct then I'm in trouble as I've got no shims to remove. If I add shims it seems to move the contact patch ever so slightly closer toward the axel line.
One last question. Am I correct in saying that if shims are added to move the P away from the CW then the backlash will increase and the adjusters need to be moved to push the CWtoward the P and vice versa if shims are removed.
Any input welcome
