Abstract:

The main goal of this research was to study the influence of involute spur gear tip relief on the contact stress at the engagement meshing point (the begining point of the line of contact A).

Different predefined involute spur gears and modification parameters (amount and length of modification) were already available from previous studies (Schmidt 2019). In this study, both the drive and the driven gear has tip relief.

The modification of the gear profile was achieved through the modification of the gear rack cutter’s profile. This way the profil modification of the gear profiles are generated during the gear generation (gear planning) process. The gears have been nitrided, so after the gear manufacturing process, the heat treatment did not defrom the modified gear profile.

The gear modifications were generated in a CAD system, and the calculations were made with FEM. The results show that the tip relief influences the magnitude of the gear contact stress at the first meshig point. With the use of tip relief modification, the contact stress of the meshing gears can be reduced at the beginning of the meshing line.
