摘要： PURPOSE:To increase the cooling effect of an apparatus by constituting one or two radial air ducts as core holder for a salient-pole coil rotor pole piece. CONSTITUTION:Core holders 12b with air ducts 16 formed therein are fitted on both sides of a laminated thin plate 11 and fixed integrally by a rivet 13 to constitute a pole piece 9. The outer peripheral part of said pole 9 is provided with an insulated coil 11, and said coil piece 9 is mounted on a spider 14 installed at a shaft 15. In a rotor having a salient-pole coil 10a thus constituted a cooling air 6 flows through the air duct 16 of said core holder 12 as shown by the arrow. In this manner, cooling of a coil can be improved on the pole piece side inside face and especially in the leeward part of the salient-pole coil 10 so that the heat stored in said part can be released readily and efficiently.

摘要： PURPOSE:To lower the temperatures of a leeward core rotor bar, an end ring and a coil end section by mounting a ventilation flue for cooling leewardly to a core hold-down and a core or a shaft. CONSTITUTION:A core 2 and core hold-downs 3, 4 are fitted to a shaft 1, and a hole 3b is bored at the same position as a core air hole 2b in order to pass core cooling air flowed out of the air hole 2b in the core hold-down 3. A ventilation flue 2a passing air in order to cool the leeward is formed to a fitting section with the shaft 1 in the core 2, and a ventilation flue 3a for flowing air flowed out of the ventilation flue 2a in the radial direction is shaped to the core hold-down 3. Since the air hole 2a is positioned where far from the air hole 2b to a rotor-bar 5 heat source, air at a temperature lower than the temperature of cooling air passed through the air hole 2b can be flowed through a leeward rotor bar 5. Accordingly, the temperature rises of the core 2 in the leeward and the rotor bar 5 can be inhibited.

摘要： PURPOSE:To maintain the replaceability of used and new grease, and prevent grease leakage from a labyrinth gap by providing a grease amount adjustment chamber in communication with either a waste oil chamber or an annular grease filling chamber at an opposite side, at a position off the oiling port of the annular grease filing chamber. CONSTITUTION:There is provided a grease amount adjustment chamber 19 communicated with a waste oil chamber 14 from a grease filling chamber 11 at the side of an oiling port 15. Also, one or more chambers 19 are formed at a position farthest from the oiling port 15 in the chamber 11. Grease fully charged into a bearing 3 as a result of oiling is forced out due to the rotation of the bearing 3 and overflows into the chamber 11. A labyrinth gap 17, however, has leakage resistance and the grease is forced out into the grease amount adjustment chamber 19 having less leakage resistance. Thus, there is no grease leakage from the gap 17 to the inside of a machine. According to this construction, used grease can be replaced by new grease via oiling, and there is no grease leakage into the labyrinth gap 17, thereby enabling maintenance workability to be improved.

摘要： PURPOSE:To reduce overall weight and to prevent corrosion of bearing by disposing first and second tubular frames composed of aluminum alloy or the like at the opposite ends of a stator core and tightening both frames to a core retainer with bolts or the like. CONSTITUTION:In a frame 43, flange 43a thereof contacts with the flange 41a of a core retainer 41 with an insulation layer 45 being applied on the contact face, and they are tightened to the core retainer 41 by means of a plurality of insulating bolts 47. Similarly, flange 44a of a frame 44 contacts with the flange 42a of a core retainer 42 with an insulation layer 46 being applied on the contact face, and they are tightened to the core retainer 42 by means of a plurality of insulating bolts 48. Outer diameter d22 of the frames 43, 44 is set shorter than the outer diameter d1 of the stator core and the frames 43, 44 are made of light material such as aluminum alloy and thereby overall weight can be reduced remarkably.

摘要： PURPOSE:To achieve an ideal anti-local heat effect by setting the gap between the inner circumferential section of a partition and the stator coil section smaller at the section close to the blow hole in a bypath while setting the gap larger at the section remote from the blow hole. CONSTITUTION:The gap alpha between the inner circumferential section of a partition 19 and the stator coil section 4a is set smaller at the section close to the blow hole 18 in a bypath 17 while set larger at the section remote from the blow hole 18, and the largest gap alpha' is set at the remotest position from the blow hole 18 on the opposite side in the circumferential direction. Since the ventilation resistance is high at the section close to the blow hole 18 while low at the section remote from the blow hole 18, cooling air led through the bypath 17 to the downstream at the other end is distributed uniformly over the entire circumference thus cooling the stator coil section 4a, located in the downstream at the other end, uniformly over the entire circumference, resulting in elimination of unbalanced temperature rise in the circumferential direction.
