　この例において、モータ軸２は、反取付側の一箇所の軸受３のみによって支持されている。このため、巻上機が組み付けられていないモータ１ａを運搬する場合に、モータ軸２またはロータのステータなどへの接触、およびモータ軸２の脱落を防ぐために、モータ軸２は固定装置６によって固定される。 In this example, the motor shaft 2 is supported by only one bearing 3 on the non-mounting side. Therefore, when transporting the motor 1a to which the hoist is not assembled, the motor shaft 2 is fixed by the fixing device 6 in order to prevent contact with the motor shaft 2 or the stator of the rotor and the motor shaft 2 from falling off. Will be done.

The fastening holes 10 at both ends are provided symmetrically with respect to the plane P. The distance between the fastening holes 10 at both ends is provided so as to be the same as the distance between the pair of fastening portions 5 of the motor 1a. The fastening holes 10 at both ends have the same shape as each other. The fastening hole 10 is provided on the line of the center line C extending in the longitudinal direction of the fixing plate 7. The center line C is a straight line parallel to the longitudinal direction of the fixing plate 7.

　図３において、モータ１ａの正面図が示される。
　一対の固定板７の各々の長手方向は、一対の締結部５を結ぶ方向と平行に向けられる。一対の固定板７の各々の厚み方向は、モータ軸２の軸方向に向けられる。一対の固定板７の各々は、モータ軸２に対して互いに回転対称に配置される。一対の固定板７の各々の切欠き９は、モータ軸２の取付側の端部の側面に側方から接触する。このとき、一対の固定板７の各々は、互いに反対方向からモータ軸２に接触する。一対の固定板７の各々は、切欠き９によってモータ軸２の側面を挟み込む。 FIG. 3 shows a front view of the motor 1a.
The longitudinal direction of each of the pair of fixing plates 7 is oriented parallel to the direction of connecting the pair of fastening portions 5. The thickness direction of each of the pair of fixing plates 7 is directed to the axial direction of the motor shaft 2. Each of the pair of fixing plates 7 is arranged rotationally symmetrically with respect to the motor shaft 2. Each notch 9 of the pair of fixing plates 7 comes into contact with the side surface of the end portion of the motor shaft 2 on the mounting side from the side. At this time, each of the pair of fixing plates 7 comes into contact with the motor shaft 2 from opposite directions. Each of the pair of fixing plates 7 sandwiches the side surface of the motor shaft 2 by the notch 9.
　長手方向の一端部において、一対の固定板７の各々の締結孔１０、および締結部５のネジ孔は、互いに重なるように配置される。長手方向の他端部において、一対の固定板７の各々の締結孔１０、および締結部５のネジ孔は、互いに重なるように配置される。 At one end in the longitudinal direction, the fastening holes 10 of the pair of fixing plates 7 and the screw holes of the fastening portion 5 are arranged so as to overlap each other. At the other end in the longitudinal direction, the fastening holes 10 of the pair of fixing plates 7 and the screw holes of the fastening portion 5 are arranged so as to overlap each other.
　図４において、モータ１ａの側面図が示される。
　一対の締結具８の一方は、重なっている一対の固定板７の各々の締結孔１０、および締結部５のネジ孔に通される。一対の締結具８の他方は、重なっている一対の固定板７の各々の締結孔１０、および締結部５のネジ孔に通される。一対の締結具８の各々の締結によって、一対の固定板７はモータフレーム４に固定される。これにより、一対の固定板７の各々は、モータ軸２をモータフレーム４に固定する。 FIG. 4 shows a side view of the motor 1a.
One of the pair of fasteners 8 is passed through the respective fastening holes 10 of the pair of overlapping fixing plates 7 and the screw holes of the fastening portion 5. The other end of the pair of fasteners 8 is passed through the respective fastening holes 10 of the pair of overlapping fixing plates 7 and the screw holes of the fastening portion 5. By fastening each of the pair of fasteners 8, the pair of fixing plates 7 are fixed to the motor frame 4. As a result, each of the pair of fixing plates 7 fixes the motor shaft 2 to the motor frame 4.
　固定装置６は、例えばモータ１ａの運搬が完了したときに、モータフレーム４から取り外される。 The fixing device 6 is removed from the motor frame 4, for example, when the transportation of the motor 1a is completed.
　続いて、図５および図６において、固定装置６によるモータ軸２の固定の他の例を説明する。
　図５は、実施の形態１に係る固定装置が適用される他のモータの側面図である。 Subsequently, in FIGS. 5 and 6, another example of fixing the motor shaft 2 by the fixing device 6 will be described.
FIG. 5 is a side view of another motor to which the fixing device according to the first embodiment is applied.
　モータ１ｂは、モータ１ａの他のモータ１である。モータ１ｂのモータ軸２の外径は、モータ１ａのモータ軸２の外径より小さい。この他の点において、モータ１ｂの構成は、モータ１ａの構成と同様である。 The motor 1b is another motor 1 of the motor 1a. The outer diameter of the motor shaft 2 of the motor 1b is smaller than the outer diameter of the motor shaft 2 of the motor 1a. In other respects, the configuration of the motor 1b is similar to the configuration of the motor 1a.
　固定装置６は、モータ１ａのモータ軸２を固定する場合と同様の手順でモータ１ｂのモータ軸２を固定する。 The fixing device 6 fixes the motor shaft 2 of the motor 1b in the same procedure as when fixing the motor shaft 2 of the motor 1a.
　図６は、実施の形態１に係る固定装置が適用される他のモータの正面図である。 FIG. 6 is a front view of another motor to which the fixing device according to the first embodiment is applied.
　モータ１ｂのモータ軸２を固定しているときに、一対の固定板７は、モータ１ａのモータ軸２を固定しているときより広い範囲で重なる。モータ１ｂのモータ軸２を固定しているときに、長手方向の両端部において、一対の固定板７の各々の締結孔１０は、モータ１ａのモータ軸２を固定しているときから中心線Ｃに垂直な方向にずれて配置される。ここで、締結孔１０は長孔であるので、締結具８が通る幅が確保される。このため、モータ１ｂにおいても、一対の固定板７の各々は、切欠き９でモータ軸２の側面を挟み込むことでモータ軸２をモータフレーム４に固定できる。 When the motor shaft 2 of the motor 1b is fixed, the pair of fixing plates 7 overlap in a wider range than when the motor shaft 2 of the motor 1a is fixed. When the motor shaft 2 of the motor 1b is fixed, the fastening holes 10 of the pair of fixing plates 7 at both ends in the longitudinal direction are centered from the time when the motor shaft 2 of the motor 1a is fixed. It is arranged so that it is offset in the direction perpendicular to. Here, since the fastening hole 10 is a long hole, the width through which the fastener 8 passes is secured. Therefore, also in the motor 1b, each of the pair of fixing plates 7 can fix the motor shaft 2 to the motor frame 4 by sandwiching the side surface of the motor shaft 2 with the notch 9.
　以上に説明したように、実施の形態１に係る固定装置６は、一対の固定板７を備える。一対の固定板７の各々は、モータ１のモータフレーム４に締結される締結孔１０を両端部に有する。モータ１は、エレベータの巻上機を駆動する。一対の固定板７の各々は、両端部の締結孔１０の間に切欠き９を有する。一対の固定板７は、各々の切欠き９でモータ１のモータ軸２の側面を挟み込むことで、モータ軸２をモータフレーム４に固定する。 As described above, the fixing device 6 according to the first embodiment includes a pair of fixing plates 7. Each of the pair of fixing plates 7 has fastening holes 10 to be fastened to the motor frame 4 of the motor 1 at both ends. The motor 1 drives the hoisting machine of the elevator. Each of the pair of fixing plates 7 has a notch 9 between the fastening holes 10 at both ends. The pair of fixing plates 7 fix the motor shaft 2 to the motor frame 4 by sandwiching the side surface of the motor shaft 2 of the motor 1 with each notch 9.
　一般に、ギア軸およびモータ軸の組付けにおいて、ギア軸およびモータ軸の回転軸は一致することが好ましい。しかしながら、部品の加工誤差および組付け誤差などによって、ギア軸およびモータ軸の回転軸に芯ズレが生じうる。このため、ギア軸およびモータ軸の回転軸について、一定の芯ズレを許容できる構造が採用される。このような構造の例として、ギア軸およびモータ軸の連結部材にフレキシブルカップリングが用いられる場合がある。 In general, when assembling the gear shaft and the motor shaft, it is preferable that the rotation shafts of the gear shaft and the motor shaft match. However, the rotation shafts of the gear shaft and the motor shaft may be misaligned due to processing errors and assembly errors of the parts. For this reason, a structure that allows a certain amount of misalignment is adopted for the rotation shafts of the gear shaft and the motor shaft. As an example of such a structure, a flexible coupling may be used for the connecting member of the gear shaft and the motor shaft.
　一方、巻上機を駆動するモータ１などのようにトルク容量の大きいモータにおいて、許容トルクなどの制限のために、連結部材としてフレキシブルカップリングが用いられない場合もある。この場合に、例えば、モータ軸２の一端部のみが軸受３によって支持される構造が採用される。このとき、ギア軸およびモータ軸２の回転軸は、モータ軸２の傾きを軸受３の許容傾き角の範囲内として調整される。ここで、モータ軸２の一端部のみが軸受３によって支持される場合に、モータ軸２は、運搬の際にステータなどへの接触または脱落などが起こりうる。このため、固定装置６は、モータ軸２を一時的に固定する。固定装置６は一対の固定板７の切欠き９によってモータ軸２の側面を挟み込んでモータ軸２を固定するので、モータ軸２に運搬のための加工が必要とならない。また、ロータとステータが接触しないので、運搬によってロータまたはステータに負荷がかかりにくい。 On the other hand, in a motor having a large torque capacity such as a motor 1 for driving a hoisting machine, a flexible coupling may not be used as a connecting member due to a limitation of an allowable torque or the like. In this case, for example, a structure is adopted in which only one end of the motor shaft 2 is supported by the bearing 3. At this time, the gear shaft and the rotating shaft of the motor shaft 2 are adjusted so that the inclination of the motor shaft 2 is within the allowable inclination angle of the bearing 3. Here, when only one end of the motor shaft 2 is supported by the bearing 3, the motor shaft 2 may come into contact with or fall off from the stator or the like during transportation. Therefore, the fixing device 6 temporarily fixes the motor shaft 2. Since the fixing device 6 fixes the motor shaft 2 by sandwiching the side surface of the motor shaft 2 by the notches 9 of the pair of fixing plates 7, the motor shaft 2 does not need to be processed for transportation. Further, since the rotor and the stator do not come into contact with each other, it is difficult for the rotor or the stator to be loaded by transportation.
　また、一対の固定板７の各々は、締結孔１０に通される締結具８によって、巻上機をモータフレーム４に締結するモータフレーム４の締結部５に固定される。 Further, each of the pair of fixing plates 7 is fixed to the fastening portion 5 of the motor frame 4 for fastening the hoisting machine to the motor frame 4 by the fastener 8 passed through the fastening hole 10.
　一対の固定板７の各々は、巻上機を組み付けるための締結部５に締結される。このため、モータフレーム４に運搬のための加工が必要とならない。 Each of the pair of fixing plates 7 is fastened to the fastening portion 5 for assembling the hoisting machine. Therefore, the motor frame 4 does not need to be processed for transportation.
　また、対称面である平面Ｐは、切欠き９を通る。一対の固定板７の各々において、平面Ｐに関して締結孔１０が対称に設けられる。一対の固定板７の各々において、平面Ｐに関して切欠き９が対称に設けられる。
　また、一対の固定板７の各々は、モータ軸２の中心軸に対して互いに回転対称な配置でモータフレーム４に固定される。 Further, the plane P, which is a plane of symmetry, passes through the notch 9. In each of the pair of fixing plates 7, the fastening holes 10 are provided symmetrically with respect to the plane P. In each of the pair of fixing plates 7, notches 9 are provided symmetrically with respect to the plane P.
Further, each of the pair of fixing plates 7 is fixed to the motor frame 4 in a rotationally symmetrical arrangement with respect to the central axis of the motor shaft 2.
　これにより、モータ軸２は、一対の固定板７の長手方向の中心において、バランスよく固定される。このため、運搬の際にモータ軸２が安定する。 As a result, the motor shaft 2 is fixed in a well-balanced manner at the center of the pair of fixing plates 7 in the longitudinal direction. Therefore, the motor shaft 2 becomes stable during transportation.
　また、一対の固定板７の各々において、両端部の締結孔１０の両方が中心線Ｃの線上に設けられる。一対の固定板７の各々において、両端部の締結孔１０の両方が中心線Ｃに垂直な方向に延びる長孔である。 Further, in each of the pair of fixing plates 7, both of the fastening holes 10 at both ends are provided on the line of the center line C. In each of the pair of fixing plates 7, both of the fastening holes 10 at both ends are elongated holes extending in a direction perpendicular to the center line C.
　これにより、固定装置６は、モータ軸２の外径が異なる複数の種類のモータ１に対して適用できる。このため、モータ１の種類ごとに固定装置６を用意する必要がない。これにより、運搬用の固定装置６の管理などが容易になる。 As a result, the fixing device 6 can be applied to a plurality of types of motors 1 having different outer diameters of the motor shaft 2. Therefore, it is not necessary to prepare a fixing device 6 for each type of motor 1. This facilitates management of the fixing device 6 for transportation and the like.
　また、一対の固定板７の各々は、互いに同一の形状である。 Also, each of the pair of fixing plates 7 has the same shape as each other.
　これにより、固定板７の製造が容易になる。また、固定装置６の部品の種類が削減される。このため、運搬用の固定装置６の管理などが容易になる。 This facilitates the manufacture of the fixing plate 7. In addition, the types of parts of the fixing device 6 are reduced. Therefore, it becomes easy to manage the fixing device 6 for transportation.
　なお、モータフレーム４は、３つ以上の締結部５を有していてもよい。また、モータフレーム４は、二対以上の締結部５を有していてもよい。このとき、例えば締結部５は、互いに回転対称な位置に設けられていてもよい。 Note that the motor frame 4 may have three or more fastening portions 5. Further, the motor frame 4 may have two or more pairs of fastening portions 5. At this time, for example, the fastening portions 5 may be provided at positions that are rotationally symmetrical with each other.
　また、切欠き９の形状は、三角形状の形状でなくてもよい。切欠き９の形状は、例えば平面Ｐに関して対称な半円状の形状、または平面Ｐに関して対称な台形状の形状などであってもよい。 Further, the shape of the notch 9 does not have to be a triangular shape. The shape of the notch 9 may be, for example, a semicircular shape symmetrical with respect to the plane P, or a trapezoidal shape symmetrical with respect to the plane P.
