Thermal Diagnostics of Friction in Self-Lubricating Plain Bearings Taking Into Account Shaft Rotation
R.S. TIKHONOV

A method of thermal diagnostics of friction is proposed, which makes it possible to determine the friction torque in self-lubricating sliding
bearings using temperature data, taking into account the rotating motion of the shaft. The temperature regime in the friction unit is described in a
fi xed cylindrical coordinate system by two heat conduction equations. The equation for the shaft contains a convective term that takes into account
the rotation of the shaft at a known speed. A technique is presented for determining the time step in the numerical solution of equations, ensuring the
convergence of the approximate solution with accuracy suitable for practical use. A comparison of calculated and experimental temperatures shows
the adequacy of the model to the real thermal process in a sliding bearing. The friction torque in the sliding bearing was determined from temperature
data by solving the inverse problem of thermal conductivity. By comparing the calculated and experimental values of the friction moment, the
effectiveness of thermal diagnostics of friction was established.
Keywords: Sliding bearing, friction, thermal diagnostics, friction torque, inverse problem.
