ABSTRACT:
Liquid-cooled rotor for electric machines including shaft means formed with axial bores for feeding and withdrawing cooling liquid, and radial bores connecting the axial bores to cooling-liquid collecting chambers surrounding the shaft means, thin-walled tubes of corrosion-resistant material forming a lining for the cooling-liquid bores, the tubes being in firm rolled-in engagement with the surfaces defining the bore, along the entire lengths thereof, and diverting members fitted, into the axial bores at locations whereat the radial bores divert from the axial bores, the diverting members connecting the axial bores, respectively, with the radial bores; and method of producing the rotor.
