PROBLEM TO BE SOLVED: To provide a water-sealing type submargible motor structure which makes slidability of a thrust bearing more effective and has cooling effect of the thrust bearing in a water-sealing type submargible motor.;SOLUTION: A water-sealing type submargible motor adopts a system in which water is enclosed in the water-sealing type submargible motor in advance, a slide bearing using the water as a lubricating liquid is used, and a thrust bearing for receiving a thrust load generated by operating a pump is lubricated by the water. In the water-sealing type submargible motor, fins (vanes) are provided at a bearing frame of the thrust bearing and attached to a rotator directly. This structure generates water flow and supplies the water to a lubrication portion, thereby improving the lubricity and obtaining cooling effect.;COPYRIGHT: (C)2012,JPO&INPIT
