A method of evaluating the tooth bearing of cylindrical gear pairs is proposed. First, a program is developed for simulating the tooth bearing numerically considering a tooth flank configuration, which is given by tooth profiles and lead curves, and an alignment error, which consists of shaft angle error and center distance error. In this paper, the contact patterns of gear pairs with a certain error under no load are calculated using this program. Secondly, the contact patterns of a pair of cylindrical gears are measured by adjusting the alignment. Comparing the contact patterns obtained by experimentation with the calculated ones under the same condition as in the experiment, we find that they agree with each other closely. This agreement can be hardly obtained when contact patterns are calculated without the tooth flank configuration error and the alignment error. In conclusion, the result shows a state of engagement of practical gear pairs with errors, and it is found that this is a valid method for evaluating the tooth bearing of cylindrical gear pairs
