Just in from the Hertzian surface Dermitt out-migrated center of rotation can be a large scale power transmission charge. For the circular Hertzian surface Lutz transmissible circumferential force and drilling torque determined [5]. The double integrals are evaluated but not closed. For the rotation angle <f the values ​​of the elliptic integrals are shown in tables. In the elliptical surface pressure (see Figure), the friction force dR = dy * npd has a tendency <r to the y-axis. The tangential force is calculated as dT dT as a component of the friction force = dR cozy.
