The stress analysis is performed as a part of TCA (Tooth Contact Analysis) for a gear drive.
Unlike the existing approaches, the proposed one does not require application of commercial codes (like
ANSYS or ABAQUS) for derivation of contactmodel and determination of contact and bending stresses. The
contacting model is derived directly by using the equations of tooth surfaces determined analytically. The
boundary element approach allows to reduce substantially the number of nodes of themodel. Determination
of stresses caused by applied load is obtained directly for the applied contacting model for any position of
meshing.
The developed approach is illustrated by stress analysis of helical gears with modified geometry.
