摘要： PROBLEM TO BE SOLVED: To provide a lubricating structure of a bearing, in which a lubricating life can be simply extended, thus attaining labor saving in maintenance with the bearing unassembled. SOLUTION: As shown in (A), in an initial status, a fluid pressure cylinder part 21 is closely filled up with operation grease G H . When the operation grease G H flows into a fluid pressure cylinder part 21, the internal pressure in a cylinder chamber 21b increases, and also fluid pressure applied to a receiving part 21d of a piston part 21c increases. Therefore, the piston part 21c starts to advance into the cylinder chamber 21b, the piston part 21c presses an extension part 19e to transmit driving force, and the movable member 19 starts to move in a direction separating from the bearing 12. As a result, as shown in (B), grease G O after deterioration moves together with the movable member 19 in a state retained in a retainer 19a, and a gap between the tip surface of the retainer 19a and the end surface of the bearing 12 is gradually filled up with non-deteriorated grease G N .

摘要： PROBLEM TO BE SOLVED: To provide a lubricating structure of a bearing, in which the lubricating life can be simply extended to save labor in maintenance with the bearing unassembled. SOLUTION: As shown in (A), in an initial status a fluid pressure operation chamber 20 is closely filled up with operation grease G H . As shown in (B), when exchanging the grease, the operation grease G H is injected into a passage 23, and passes through a passage 24 from the passage 23, and the operation grease G H flows into the fluid pressure operation chamber 20. As the injection amount of the operation grease G H increases, the internal pressure in the fluid pressure operation chamber 20 increases, and the fluid pressure applied to a pressure receiving part 19b of a movable member 19 also increases, so that the movable member 19 starts to move in a direction separating from the bearing 12. As a result, deteriorated grease G O is moved together with the movable member 19 in a state of being retained in a retainer 19a, and a gap between the tip surface of the retainer 19a and the end surface of the bearing 12 is gradually filled up with non-deteriorated grease G N .

In this motor, coils 55 for voltage sensors are passed through one or a plurality of the slots for coils among many slots for coils and coils for voltage sensors are wound on the outside surface of the stator core.

摘要： PROBLEM TO BE SOLVED: To reduce the torque difference to match the actual torque with a desired torque. SOLUTION: A main circuit is constituted of a VVVF inverter 1 which converts a direct current into an alternating current of an arbitrary frequency, and an induction motor 2 which his driven by connecting with the alternating- current side of the VVVF inverter 1. An induction motor controller comprises a frequency command generating means 13 which generates a primary frequency command based on a motor constant, and a means which controls the VVVF inverter 1 so that a primary frequency following the primary frequency command generated by the frequency command generating means 13 is inputted to the induction motor 2.

摘要： PROBLEM TO BE SOLVED: To provide a fully closed rotating electric machine capable of attaining maintenance saving by restraining a temperature increase at a bearing part and preventing early deterioration of lubricating grease, thus extending a non- disassembly period. SOLUTION: In this fully closed rotating electric machine 1 which supports a shaft 9 by the bearings 5, 7 so as to be rotatable, thermal insulation layers 12a, 12b are provided at a surface coming into contact with inside air in supporting parts 6, 8 of the bearings 5, 7. The amount of heat which is generated in the fully closed rotating electric machine 1 and transmitted to the bearing supporting parts 6, 8 by heat transfer via the inside air is reduced by thermal insulation layers 12a, 12b to minimize the increase in the temperature of the bearing supporting parts 6, 8 and the bearings 5, 7. It is thus possible to prevent the lubricating grease of the bearings 5, 7 from deteriorating early, and extend the non-disassembly period for maintenance saving. Moreover, since this method can be used merely by making thermal insulation materials 13a, 13b adhere to a surface coming into contact with the inside air in the bearing supporting parts 6, 8, it is thus possible to facilitate the use of this method for a conventional fully closed rotating electric machine.
