  • Publication number: 20120155790
    Abstract: The invention provides a horizontal shaft type rotary machine capable of simply feeding oil into thrust bearing devices. Leak oil introduction means are provided in the circumferential end parts of thrust bearing devices, for introducing leak oil of lubrication oil from horizontal type slide bearing devices onto slide surfaces of the thrust bearing devices. With this configuration, the thrust baring devices can be lubricated with the use of leak oil of lubrication oil from the horizontal type slide bearing devices, and as a result, it is possible to eliminate the necessity of an oil feed system exclusively used for the thrust bearing devices, thereby it is possible to simplify the pipe line arrangement of the oil feed system and the control of oil feed quantity.

  • Patent number: 8049378
    Abstract: The invention aims at providing a forced cooling rotary electric machine capable of bringing temperature distribution close to a designed temperature distribution and avoiding becoming a larger size, and employs a wedge formed with ventilation grooves and a wedge not formed with the ventilation grooves to regulate the flow rates of cooling gas passing through air ducts, so that the cooling gas supplied to a part of a stator core, in which temperature is low, can be caused to flow positively to a part in which the temperature is high and the temperature distribution in the axial direction of the stator core can be uniformized. As a result, the temperature distribution in the axial direction of the stator core can be brought close to a designed temperature distribution, and a forced cooling rotary electric machine that need not be made larger in size with a margin can be obtained.
