A complete proposal of induction shrink fit between a disk and shaft is presented. The proposal consists of two parts. First, a suitable interference between both parts has to be suggested that is be able to transfer the required mechanical torque at a permissible mechanical stress. Then, the process of induction heating of the disk before its putting on the shaft is mapped. The model of the process respecting all nonlinearities is solved numerically in the hard-coupled formulation. The methodology is illustrated with the example of induction shrink fit between the active wheel of gas turbine and shaft.
