CONTACT CHECK AND ADJUSTMENT OF
BEVEL GEAR TEETH
Give bevel gear set a pinIon-crown clearance
of 0.10-0.15 mm. (.0039-.0059") and before check-
ing teeth contact make sure of corresponden-
ce of planes formed by gear set outer surfaces
normal to generating pitch line (see A on Fig.
66).
Teeth contact check is carried out as follows :
smear crown teeth with lead oxide and then
rotate pinion keeping crown braked so that
rotation will take place under load and con-
tact marks will appear on painted surface
of crown .
Contact is correct when marks left by pinion
teeth on crown teeth are even all along flank
(see Fig. 89).
Contact between teeth could be incorrect and
the following instances might arise:
1 - Excessive contact at bottom of tooth flank
(see Fig. 90). This means that pinion is too

deeply inserted into crown. Withdraw pin-
ion reducing adjusting shims .
2 - Excessive contact at tooth heel (see Fig .
91). This means that crown is too far apart
from pinion. Approach crown to same adop-
ting an
ols
shim.
3 - Excessive contact at tooth crest (see Fig .
