Inspection
1.

Check the tooth contact pattern.

Tooth contact

Contact state

Solution

Standard contact

 

 

1. Heel contact

Increase the thickness of the pinion height adjusting shim, and position the drive pinion closer to the center of the drive gear.

Also, for backlash adjustment, reposition the drive gear further from the drive pinion.

2. Face contact

3. Toe contact

Decrease the thickness of the pinion height adjusting shim, and position the drive pinion further from the center of the drive gear.

Also, for backlash adjustment, reposition the drive gear closer to the drive pinion.

4. Flank contact

note
1.

Tooth contact pattern is a method for judging the result of the adjustmentof drive pinion height and final drive gear backlash. The adjustment of drivepinion height and final drive gear backlash should be repeated until the toothcontact patterns are similar to the standard tooth contact pattern.

2.

When you cannot obtain a correct pattern, the drive gear and drive pinionhave exceeded their limits. Both gears should be replaced as a set.
