<P>PROBLEM TO BE SOLVED: To provide an electromotive drive device which can efficiently collect lubricating oil without reducing a stiffness of shaft supporting section. <P>SOLUTION: The electromotive drive device 1 is characterized in that a rotor 6, a rotor shaft 7 and a stator 8 are housed in a case, in that a first oil storage section 10 and a second oil storage section 11 are provided within the case, in that the rotor shaft 7 includes an oil supply channel 20 supplying oil to a lubricated section and a cooled section, in that the first oil storage section 10 is arranged beneath a case 2, in that the second oil storage section 11 is located between one end of the rotor shaft 7 and the case 2, and in that an oil 9 stored in the first oil storage section 10 is scraped up by a rotation of the rotor 6, and supplied to the second oil storage section 11, and the lubricated section and the cooled section through the oil supply channel 20. Furthermore, a third oil storage section 12 is arranged in a periphery of bearing boss of the rotor shaft 7, or a more upstream side of the case 2 than the second oil storage section 11, and communicated to the second oil storage section 11 through a communicating oil channel 29. <P>COPYRIGHT: (C)2009,JPO&INPIT |
