Abstract
In a combined power system, a rotating shaft of a rotating electric machine includes a hollow cylindrical outer shaft and an inner shaft inserted into the hollow interior part of the outer shaft. The inner shaft includes a projecting distal end exposed from the outer shaft. On the projecting distal end, a rotational parameter detector, a retaining member and a restraining member are disposed. The retaining member supports the rotational parameter detector at the projecting distal end. Further, the inner shaft is restrained to the outer shaft by the restraining member.
Claims12
A rotating electric machine system comprising a rotating electric machine and a rotating electric machine housing configured to rotatably support a rotating shaft of the rotating electric machine,
- wherein the rotating shaft includes a hollow cylindrical outer shaft, and an inner shaft configured to be removably inserted in a hollow interior part of the outer shaft;
- the outer shaft includes a first outer shaft end part and a second outer shaft end part that are positioned opposite to each other in an axial direction of the rotating shaft;
- the inner shaft includes a first inner shaft end part and a second inner shaft end part that are positioned opposite to each other in the axial direction;
- and
- the first inner shaft end part of the inner shaft includes a projecting distal end that is exposed from the first outer shaft end part of the outer shaft;
- the rotating electric machine system comprising:
- a rotational parameter detector provided on the projecting distal end, and configured to detect a rotational parameter of the rotating shaft;
- a retaining member provided on the projecting distal end, and configured to retain the rotational parameter detector on the projecting distal end;
- and
- a restraining member provided on the projecting distal end, and configured to restrain the inner shaft to the outer shaft.
A combined power system that is equipped with a rotating electric machine system and an internal combustion engine, the rotating electric machine system including a rotating electric machine, the internal combustion engine including an output shaft configured to rotate integrally with a rotating shaft of the rotating electric machine,
- wherein the rotating shaft includes a hollow cylindrical outer shaft, and an inner shaft configured to be removably inserted in a hollow interior part of the outer shaft;
- the outer shaft includes a first outer shaft end part and a second outer shaft end part that are positioned opposite to each other in an axial direction of the rotating shaft;
- the inner shaft includes a first inner shaft end part and a second inner shaft end part that are positioned opposite to each other in the axial direction;
- and
- the first inner shaft end part of the inner shaft includes a projecting distal end that is exposed from the first outer shaft end part of the outer shaft;
- the rotating electric machine system comprising:
- a rotational parameter detector provided on the projecting distal end, and configured to detect a rotational parameter of the rotating shaft;
- a retaining member provided on the projecting distal end, and configured to retain the rotational parameter detector on the projecting distal end;
- and
- a restraining member provided on the projecting distal end, and configured to restrain the inner shaft to the outer shaft;
- wherein the output shaft is connected to at least one of the second outer shaft end part or the second inner shaft end part.
