Abstract
The present disclosure is directed to a shaft alignment tool including a base, a rotational body mounted on the base for relative rotation with respect to the base, and an alignment meter coupled to the rotational body.
Claims20
A shaft alignment tool comprising:
- a base including a shaft attaching mechanism for attaching the shaft alignment tool to an end surface of a first shaft to be aligned with a second shaft, the base further including a base shaft protruding axially from the base;
- a rotational body mounted on the base shaft of the base through one or more bearings for relative rotation with respect to the base, wherein the rotational body is aligned co-axially with the first shaft;
- and
- an alignment meter coupled to the rotational body for providing alignment measurements between the first shaft and the second shaft.

A method of aligning a first shaft and a second shaft, the method comprising:
- coupling a shaft alignment tool to an end surface of the first shaft, wherein the alignment tool includes a base attached to the end surface of the first shaft through a shaft attaching mechanism, and a rotational body mounted on a base shaft protruding axially from the base through one or more bearings;
- aligning, co-axially, the rotational body of the shaft alignment tool with the first shaft;
- rotating the rotational body;
- and
- performing the radial alignment between the first shaft and a second shaft based on the rotating of the rotational body and using an alignment meter coupled to the rotational body.
2 more elements
A shaft alignment tool comprising:
- a base having a base shaft extending normal with respect to a front side of the base, the base including a shaft attaching mechanism for attaching the shaft alignment tool to an end surface of a first shaft to be aligned with a second shaft;
- a rotational body mounted on the base shaft through one or more bearings for relative rotation with respect to the base, wherein the rotational body is aligned co-axially with the first shaft;
- at least one arm extending radially from the rotational body;
- and
- an alignment meter coupled to the at least one arm for providing alignment measurements between the first shaft and the second shaft.
