Abstract

A rotor securing jig secures a rotor extending along an axis inside a container. The rotor securing jig includes a first member that is able to be secured to a first end portion of the rotor, which is an end portion of the rotor on a first side in an axial direction, a second member that is provided relatively movable in the axial direction with respect to the first member, and a third member that is secured to the container, has a first abutting surface facing a second side in the axial direction, which is an opposite side to the first side, and abutting the first member, and has a second abutting surface facing the first side and abutting the second member.

First claim

What is claimed is:

1. A rotor securing jig comprising:
a first member that is able to be secured to a first end portion of a rotor, which is an end the portion of the rotor on a first side in an axial direction;
a second member that is provided relatively movable in the axial direction with respect to the first member; and
a third member that is configured to be secured to a container, and has a first abutting surface facing a second side in the axial direction, which is an opposite side to the first side, and configured to abut the first member, and a second abutting surface facing the first side and configured to abut the second member,
wherein the first member is separate from the rotor,
the first member has a cylindrical portion that is configured to allow the first end portion of the rotor to be inserted therein from the second side,
the second member has an insertion portion that is configured to be inserted into the cylindrical portion from the first side and a flange portion that protrudes outward from an end portion of the insertion portion on the first side in a radial direction,
the first member and the second member are relatively movable in a state where the insertion portion is inserted in an inner circumferential surface of the cylindrical portion, and
the first abutting surface of the third member comes into contact with the cylindrical portion, and the second abutting surface comes into contact with the flange portion.

2. The rotor securing jig according to claim 1 ,
wherein the cylindrical portion has a cylindrical shape,
the insertion portion has a columnar shape having an outer circumferential surface that is configured to come into sliding contact with the inner circumferential surface of the cylindrical portion, and
the first member and the second member are relatively movable by engaging a female screw portion formed in the inner circumferential surface of the cylindrical portion with a male screw portion formed in the outer circumferential surface of the insertion portion.

3. The rotor securing jig according to claim 2 ,
wherein a first hole recessed in the radial direction is formed in an outer circumferential surface of the cylindrical portion.

4. The rotor securing jig according to claim 2 ,
wherein a second hole recessed in the radial direction is formed in an outer circumferential surface of the flange portion.

5. A rotor storage unit comprising:
the rotor securing jig according to claim 1 ; and
a container to which the third member of the rotor securing jig is secured,
wherein an inside of the container is sealable.

6. The rotor securing jig according to claim 3 ,
wherein a second hole recessed in the radial direction is formed in an outer circumferential surface of the flange portion.

7. A rotor storage unit comprising:
the rotor securing jig according to claim 1 ; and
a container to which the third member of the rotor securing jig is secured,
wherein an inside of the container is sealable.

8. A rotor storage unit comprising:
the rotor securing jig according to claim 2 ; and
a container to which the third member of the rotor securing jig is secured,
wherein an inside of the container is sealable.

9. A rotor storage unit comprising:
the rotor securing jig according to claim 3 ; and
a container to which the third member of the rotor securing jig is secured,
wherein an inside of the container is sealable.

10. A rotor storage unit comprising:
the rotor securing jig according to claim 4 ; and
a container to which the third member of the rotor securing jig is secured,
wherein an inside of the container is sealable.

11. A rotor storage unit comprising:
the rotor securing jig according to claim 6 ; and
a container to which the third member of the rotor securing jig is secured,
wherein an inside of the container is sealable.
