Abstract:
1. An airplane engine accessory box comprising: a casing of the airplane accessory box that includes a material that is a good conductor of heat having mounted thereon a stator of an electrical machine having a rotor guided in a bearing carried by a support part made of a material having a relatively small coefficient of thermal expansion, wherein the support part of the bearing is carried by a stator cover of the electrical machine, the support part of the bearing being secured in an orifice of the stator cover and being centered in a corresponding orifice of the casing of the airplane accessory box, said stator cover being pressed against the casing of the airplane accessory box and being made of a material that is a good conductor of heat, having thermal conductivity that is relatively much greater than that of the support part in order to form a heat bridge between the stator of the electrical machine and the casing of the box.
