INDUCTION HEATING INSTALLATION FOR MOUNTING AND DISMOUNTING OF UNITS COMPRISING PARTS FAIRED BY SHRINK FIT Russian patent published in 2003 - IPC

FIELD: technological equipment for assembly and disassembly of units of machines and mechanisms which parts are faired by shrink fit. SUBSTANCE: installation is supplemented with unit of automatic adjustment of output frequency of converter, with set of separable inductors. Number of turns of winding of each inductor is chosen from its operation conditions in interval of automatic resonance frequency control which ensures specified rate of heating for entire assortment of parts making up unit with fixed value of capacitance of capacitor of resonance circuit. Secondary winding of matching transformer is made sectional, number of its sections correspond to number of groups of inductors. Each section overlaps range of rated output power in fixed interval of automatic frequency control, fixed value of capacitance of resonance circuit and specified value of output voltage. Number of groups of inductors or sections of secondary winding of matching transformer is determined by relation of interval of power values required for provision of specified rate of heating of entire assortment of parts of given unit to power interval corresponding to individual group[ of inductors. EFFECT: reduced production area and labor input to process. 1 cl, 3 dwg
