In this work mathematical model describing the heat generation and its propagation in the mechanical friction clutch is presented and used. The proposed model takes into account the thermal conductivity of friction linings materials, the heat transfer between the friction linings of clutch and its surrounding environments, as well as the unequal distribution of flux density of generated heat in the clutch. The analyzed system is described by a set of algebraic linear equations, and it is derived using a computer numerical method. Both examples of numerical and experimental results are obtained and discussed. Work carried out in experimental studies were designed to confirm the presented mathematical model. Simple qualitative experimental verification of the model indicates a relatively good qualitative agreement with numerical results to the experimental ones. Relatively simple experiments carried out revealed that the proposed mathematical model describes the phenomenon well enough heat present in the real friction clutches.
