Coloring method is adopted in the inspection of the mesh print. Smear red-lead paint
evenly on the faces of the bevel gear teeth. Turn the bevel gears several times until the distinct
contact traces are imprinted on the teeth faces of the bevel pinion. The print imprinted on the
teeth faces of the bevel pinion is mesh print. As the spiral direction of the bevel pinion is right-
handed, when the tractor forwards, the force is applied on the concave face of the bevel
pinion, the readlead paint should be smeared on the convex face of the bevel gear; while the
tractor reverse, the force is applied on the convex face of the bevel pinion, the red-lead paint
should be smeared on the concave face of the bevel gear
.
