Document Type and Number:
Japanese Patent JP2016174456
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a multiple gap type rotary in which the cooling performance of a stator winding is enhanced.SOLUTION: A multiple gap type rotary which includes a rotating shaft, a rotor, an inner core and an outer core at the inside and outside of the rotor, an inner stator winding of the inner core, an outer stator winding of the outer core, a side surface stator winding for connecting the inner stator winding and the outer stator winding, a side space in which the side surface stator winding is mounted, and an oil supply port for supplying oil into the space, includes an oil flow adjusting member disposed between a frame and the side surface stator winding in the side space, and an uneven surface which is a surface facing the side surface stator winding of the oil flow adjusting member via an oil flow gap. An oil guide path comprising convex portions and concave portions provided to the uneven surface extends to a direction more spread to the right and left sides from the center of the unevenness in the downward direction at the upper side of the axial center horizon, and also extends from the right and left ends to the center of the unevenness in the downward direction at the lower side of the axial center horizon.SELECTED DRAWING: Figure 1
