Profeller Shaft and Differential
Gear Contact Area
To proof whether the driven conic gear and drive conic gear mesh correctly, the shape of contact area should
be checked. If the hyperbola gear mesh mesh incorrectly, it will cause noise and shorten the duration of the gears.
1. Wash the gears of driven conic gear and drive conic
2 .Select 3~4 gears of driven gear which are near
drive gear and wipe a flat of ferric oxide.
3 .Turn connecting flange by hand to turn driven conic
gear positive and negative.
If the caculated clearance value and the thickness are
correct, the shape of gear contact area will be normal. But
A.Adjust approch：Increase the thickness of the gasket of drive gear to close it to driven gear.
B.Adjust approch：Decrease the thickness of the gasket of drive gear to keep away it from driven gear
After adjusting, wipe up the ferric oxide.
