Abstract
A measurement gauge for a stator that includes a height gauge part having at least one base surface, legs, and a height checking surface. The base surface faces in a first direction to define a base plane configured to abut an end surface of a core of the stator. The legs are spaced apart in a circumferential direction about an axis and extend in the first direction from the base surface. The legs are configured to be received in holes defined by the core of the stator. The height checking surface is parallel to the base plane and spaced apart therefrom by a predetermined distance. The height checking surface having an annular shape disposed about the axis.
Claims20
A measurement gauge for a stator, the measurement gauge comprising:
- a height gauge part including:
- at least one base surface facing in a first direction to define a base plane configured to abut an end surface of a core of the stator;
- a plurality of legs spaced apart in a circumferential direction about an axis and extending in the first direction from the at least one base surface, the legs being configured to be received in holes defined by the core of the stator;
- and
- a first height checking surface parallel to the base plane and spaced apart therefrom by a predetermined distance, the first height checking surface having an annular shape disposed about the axis.
A measurement gauge for a stator, the measurement gauge comprising:
- a first diameter gauge part including:
- an annular shaped base surface facing in a first direction and configured to abut an end surface of a core of the stator;
- a plurality of legs spaced apart in a circumferential direction about an axis and extending in the first direction from the base surface, the legs being configured to be received in holes defined by the core of the stator;
- a first diameter checking surface extending in the circumferential direction;
- and
- a second diameter checking surface extending in the circumferential direction and being recessed in a second direction relative to the first diameter checking surface, the second direction being perpendicular to the first direction.
A measurement gauge for a stator, the measurement gauge comprising:
- a first gauge part including:
- at least one base surface facing in a first direction to define a base plane configured to abut an end surface of a core of the stator;
- a plurality of legs spaced apart in a circumferential direction about an axis and extending in the first direction from the at least one base surface, the legs being configured to be received in holes defined by the core of the stator;
- and
- a first height checking surface parallel to the base plane and spaced apart therefrom by a first predetermined distance, the first height checking surface having an annular shape disposed about the axis;
- at least one second height checking surface parallel to the base plane and spaced apart therefrom by a second predetermined distance that is greater than the first predetermined distance;
- and
- a second gauge part slidably engaged along a periphery of the first gauge part in a circumferential direction.
