摘要： PROBLEM TO BE SOLVED: To provide a lubricating structure of a bearing which can extend a lubrication life and save work in maintenance.SOLUTION: When an opening/closing part 22 is loosened to open a supply/discharge port 21a, a fluid in a bag body 20 is discharged to the outside from the supply/discharge port 21a through piping 21. As a result, an internal pressure of the bag body 20 decreases to shrink the bag body 20 and to increase a volume of an annular filling chamber 14b, forming a space Sbetween the chamber and a bearing 12. When the opening/closing part 22 is fastened to close the supply/discharge port 21a and further a new grease Gis injected through a flow passage 16d, the new grease Gis made to pass through the bearing 12 and fed to an annular filling chamber 14b on a side close to a bearing lid 14. As a result, an old grease Ginside the annular filling chamber 14b and a degraded grease inside the bearing 12 are pushed and expelled to a bottom of the annular filling chamber 14b, while the new grease Gis intermediately supplied to replenish to the space Sbetween the old grease Ginside the annular filling chamber 14b and the bearing 12.

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. The induction motor controller is provided with a torque difference index computing means 16 which outputs a torque difference index indicating that there is a difference between a desired torque and the actual torque with respect to the induction motor 2, and a primary frequency correcting means 17 which corrects the primary frequency so as to reduce the torque difference index outputted from the torque difference index computing means 16.

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.

摘要： PROBLEM TO BE SOLVED: To enable to run freely and smoothly on small curved rails, by connecting the steering mechanism fixed to the support frame and the rotator with a coupling mechanism and transmitting the longitudinal such as the tractive force and the braking force generated by the rotor, and the rotating force by tractive force to the support frame. SOLUTION: In an axle 6A having a wheel 1A, a steering link 39 is connected with a detent arm 24A and then coupled to a steering triangle link 32. Further, the steering link 39 is coupled with a steering triangle link 31 on the opposite side via a coupling link 50. Here, the steering triangle links 31, 32 are supported by steering triangle link catches projecting from the bogie frame. Similarly, an axle 6B having a wheel 1B constructs a steering mechanism. A steering connection link 51 is disposed between the steering triangle links 31, 32 which turn the wheels 6A, 6B on front and rear in opposite direction by a same amount. The steering triangle links 31, 32 receive not only the lateral direction force from the motor rotator assembled to the wheels 1A, 1B, but also a force in rotating direction.

摘要： PROBLEM TO BE SOLVED: To provide a gauge variable truck in which a wheel and a wheel bearing can be easily replaced at the time of maintenance. SOLUTION: In a gauge variable truck 100, an inner ring of a wheel bearing for rotatably supporting a wheel 41 is fitted to a wheel fitting surface 33 of an axle outer cylinder 30 in such a manner as to freely slide, and clamped by a ring nut 46 and a projecting part 32 of the axle outer cylinder 30 to be fixed undisplaceably in the axial direction. A motor frame and a web of the wheel 41 are integrally screw-fitted. Thus, after the axle outer cylinder 30 is removed from a fixed axle 24, the ring nut 46 is removed, and if the motor frame and the wheel 41 are separated, the wheel 41 and the wheel bearing can be easily removed from the axle outer cylinder 30.

摘要： PURPOSE: To prevent filling grease in grease filling chambers from being moved in a bearing even though it receives centrifugal force, by forming the outside diameters of outer circumferential walls of the geese filing chambers shorter than the inside diameter of the outer wheel of a rotating machine side bearing. CONSTITUTION: End covers 19, 20 have projected parts which are built into recessed parts of annular stepped members respectively formed to an end cover 18 and a rotor frame 7, and grease filling chambers 21, 22 opened in a bearing are respectively formed to these projected parts and filled with lubricating grease. The grease filling chambers 21, 22 are formed in the projected parts of the end covers 19, 20 attached to a rotor member 15, and the outside diameters d2 . of the outer circumferential walls of the chambers 21, 22 are formed smaller than the inside diameter d1 of a bearing outer ring 8a so that lubricating grease filled in the grease filling chambers 21, 22 may not be rotated during operation therefore, centrifugal force may not be acted thereon, and the lubricating grease is prevented from being moved in the bearing and kept under a stable condition. Further, only base oil separated from the lubricating grease by being used for 6 long period of time is supplied in the bearing so that stable lubrication can be maintained.

摘要： PROBLEM TO BE SOLVED: To control overcurrent, temperature rise, and drop in the car thrust. SOLUTION: This electric vehicle drive and control device, whose main circuit is made up of a VVVF inverter 1 that converts DC into AC or an arbitrary frequency; a filter capacitor connected to the DC side of the VVVF inverter 1; and an electric vehicle electric motor 2 connected to the AC side of the VVVF inverter 1, and which is provided with a speed-estimating means 9 that obtains the estimated value of speed, by presuming the rotational speed of the electric motor 2 from the output voltage command and the output current of the VVVF inverter 1, drives and controls the electric motor 2 by controlling the VVVF inverter 1, based on the presumed value of speed obtained from the speed-estimating means 9. This device is further provided with a speed abnormality detecting means 10, that detects that the presumed value of speed obtained by the speed-estimating means 9 converges into an abnormal value, and a protective means 11 that stops the VVVF inverter 1, if the speed abnormality detecting means 10 determines that the estimated value of speed is converging to an abnormal value.
