Definitions
- the present invention relates to a permanent magnet type rotating electrical machine having a rotor cantilever support structure that supports only one end of a shaft of a rotor via a bearing provided on one side of a rotating electrical machine casing, and a vehicle such as a railway vehicle using the same.
- the present invention relates to a permanent magnet type rotating electrical machine system.
- wound-type generators and induction motors have been used as rotating electrical machines used in railway vehicles.
- the size and weight of the permanent magnets have increased due to higher performance and lower prices of permanent magnets and the spread of high-performance inverters.
- Motivation to adopt a permanent magnet type rotating electrical machine that enables higher efficiency and higher efficiency is increasing.
- Such a rotor cantilever support structure of a rotating electrical machine continues until it is directly connected to the prime mover.
- a rotating electrical machine for example, a generator
- the rotor is wound, and the rotor becomes an electromagnet by supplying current to the winding. For this reason, unless a current is supplied to the rotor, no magnetic flux exists in the generator and no magnetic attractive force or the like is generated.
- a permanent magnet generator when a permanent magnet generator is applied, since there is a permanent magnet in the rotor, magnetic flux always exists in the generator, and a magnetic attractive force is generated in the gap between the rotor and the stator.
- the rotor of the cantilevered support structure is able to restrain the movement until it is directly connected to the prime mover. Is required. Moreover, since it is necessary to disconnect the connection part of a motor and a generator at the time of maintenance of a motor and a generator, the structure which can restrain a movement of a rotor also at the time of a maintenance is required.
- Patent Documents 1 and 2 for example, as a transport protection device for a cantilevered rotary motor used in an elevator hoisting machine, the side that is not supported by the bearing of the rotor of the motor is screwed to the end face of the flange portion of one end of the motor casing.
- a technology is disclosed in which a pair of fixed plates that are stopped are sandwiched from the radial direction of the rotor shaft to restrain the movement of the rotor in the radial direction and the axial direction. More specifically, in Patent Document 1, the fixed plate is concavo-convexly fitted with the flange end surface of the motor casing, and one end of each fixed plate is engaged with a stepped portion provided on the outer periphery of the rotor shaft.
- Such a restraint structure is an effective transportation protection means in an elevator-specific rotating electrical machine that is relatively small compared to, for example, a railway vehicle generator.
- a permanent magnet type rotating electric machine having a child cantilever support structure When applied to a permanent magnet type rotating electric machine having a child cantilever support structure, it cannot be said to be sufficient for the following reason.
- the magnetic attraction force inside the rotating electrical machine is very large. Therefore, if an external force acts in the rotational direction before the direct connection to the prime mover, It is expected that restraints will not be adequately addressed.
- Patent Document 3 a spacer for preventing adsorption is provided between the rotor and the stator, and the spacer can be removed after the rotating machine is assembled. Since this structure is intended to prevent adsorption between the rotor and the stator, it is not a structure in which the rotor itself is fixed. Therefore, it cannot fully cope with the rotation direction (circumferential direction) constraint of the rotor as in the cantilever support structure. In addition, it takes relatively time to remove the spacer, and once the spacer is removed, it is difficult to attach it again, and there are points to consider in terms of assembly and maintenance.
- the present invention has been made in view of the above points, and even if it is a permanent magnet type rotating electrical machine having a large capacity (large magnetic attraction force) and a rotor cantilever support structure, the rotation before coupling with the prime mover
- An object of the present invention is to provide a permanent magnet type rotating electrical machine that can sufficiently cope with not only the axial direction and radial direction of the rotor but also the rotational direction (circumferential direction) as the restraint structure of the rotor.

- the permanent magnet type rotating electrical machine in which one end of the shaft not supported by the bearing can be connected to one end of the shaft of the prime mover has the following characteristics.
- the side of the rotor shaft that is not supported by the bearing is constrained to one end surface of the casing so that movement in the axial direction, radial direction, and circumferential direction is constrained when the shaft of the rotor is disconnected from the shaft of the prime mover. It is connected via a connecting member.
- One end side of the constraining connecting member is attached to a shaft end surface on the side not supported by the bearing of the rotor shaft via a screw member, and the other end side is attached to one end surface of the casing via a screw member. It is attached.
- the shaft of the rotor is integrally provided with a flange for directly connecting to the shaft of the prime mover at the end of the shaft that is not supported by the bearing, and one end side of the constraining connecting member is connected to the shaft.
- the rotor shaft is provided with a first flange portion and a second flange on the shaft that is not supported by the bearing, and the first flange portion is provided on the shaft of the prime mover.
- the rotor is provided at one end of the rotor to be directly connected to the shaft, the second flange portion is provided corresponding to the restraining connecting member, and the one end side of the restraining connecting member is the second
- the one end surface of the flange portion may be attached via a screw member, and the other end side may be attached to the one end surface of the casing via the screw member.
- the present invention even in a permanent magnet type rotating electrical machine having a large capacity (large magnetic attraction force) rotor cantilevered support structure, only the axial direction and the radial direction of the rotor are required before being connected to the prime mover.
- a rotor restraint structure excellent in protection of rotating electrical machines that can sufficiently cope with restraint in the rotational direction (circumferential direction).
- the constraining connecting member can be easily attached and detached, it is possible to provide a permanent magnet type rotating electrical machine that can contribute to simplification of assembly work and maintenance work of the rotating electrical machine.
