Patterns of tooth contact marking of helical gears with pressure angle error, with pressure angle error plus alignment error, and with pressure angle error plus longitudinal crowning tooth trace correction were calculated and compared with measured patters. Measured and calculated tooth fillet stresses of these gears were also compared. The comparison showed good agreement and certified the reliability of the analyzing method for tooth contact marking and gear stress state. for tooth fillet stress, contact stress and flash temperature, the rate of increasing owing to gear error is discussed in relation with tooth bearing: When the amplitude of pressure angle error and longitudinal crowning changes, the stress increasing rate show two different characteristics, which correspond to the difference in the changing fashion of the tooth contact marking pattern. When a gear has concave tooth form error and pressure angle error, the stress increasing rate can be large in spite of a state of good tooth bearing.
