Abstract
An apparatus and method for aligning a housing such as a flywheel housing with a crankshaft or other rotating member. The apparatus includes a main shaft and a mount by which the main shaft is mounted to the center axis of a member rotating in a housing. A sleeve is received upon and rotates relative to the main shaft and is provided with a mount for a dial indicator. The dial indicator is positioned so that any misalignment between the rotating member and the housing is output by the dial indicator as the sleeve is rotated relative to the housing. Depending upon the output of the dial indicator, the position of the housing is changed relative to the rotating member to align the center axis of the rotating member with the center axis of the housing.
Description
- The present invention relates to an apparatus and method for aligning a housing with a member rotating therein. More specifically, the present invention relates to an apparatus for mounting to a rotating member for centering, or aligning, the rotating member within a housing and a method for using that apparatus for centering the rotating member within the housing.
- Certain diesel engines require that the engine and transmission be properly aligned to avoid drivetrain failure. In such drivetrains, the engine and transmission are not directly connected to each other; instead, they bolt to an aluminum flywheel housing and the flywheel housing must be precisely aligned to the engine crankshaft. For instance, CUMMINS® and MACK® diesel engine manufacturers require a tolerance of 0.006″ at the top, bottom, and side of the flywheel housing.
- The current method used to align the flywheel housing to the engine crankshaft utilizes a standard dial indicator with a magnetic base. The magnetic base is attached to the crankshaft which is steel. The dial indicator is positioned to contact the inside mating surface of the flywheel housing where the transmission makes contact. To check alignment, one man must turn the crankshaft from the front of the engine, and must use a large wrench to do so to overcome engine compression. Another man is required at the back of the engine at the flywheel housing to read the dial indicator and make the necessary adjustments to bring the housing in line with the crankshaft. This method requires a great deal of physical exertion and is very time consuming. There is also a chance that the magnetic base will move during alignment such that the alignment is not precise.
- There is, therefore, a need for an improved method for aligning a rotating member with the housing in which the member rotates, and it is an object of the present invention to provide such a method.
- It is also an object of the present invention to provide an improved apparatus for aligning a rotating member with the housing in which the member rotates.
- Another object of the present invention is to provide an apparatus and method for aligning a housing with a member rotating within the housing using a tool with which engine mechanics are familiar, namely, a dial indicator.
- Another object of the present invention is to provide a method for aligning a rotating member with the housing in which the member rotates that can be performed by one person.
- Yet another object of the present invention is to provide an apparatus and method for aligning a crankshaft with a flywheel housing with improved accuracy.
- Other objects, and the advantages, of the present invention will be made clear to those skilled in the art by the following description of the presently preferred embodiments thereof.
- These objects are achieved by providing an apparatus for aligning a housing with a member rotating within the housing with a dial indicator comprising a main shaft, a mount for aligning the main shaft with the center axis of a member that rotates within a housing, and a sleeve that is received upon the main shaft for turning relative to the main shaft. The sleeve comprises a mount to which a dial indicator is mounted, the dial indicator being mounted in a position in which the contact point thereof contacts the housing when the sleeve is turned for outputting a measurement of any misalignment between the housing and the rotating member.
- The present invention also provides a method for aligning a housing with a member rotating therein using a dial indicator comprising the steps of mounting a main shaft on a member rotating within a housing in alignment with the center axis of the rotating member, rotating a sleeve having a dial indicator mounted thereto on the main shaft with the contact point of the dial indicator in contact with the housing, and adjusting the position of the housing relative to the center axis of the rotating member until the dial indicator outputs a measurement indicating acceptable alignment between the housing and the center axis of the rotating member.
- FIG. 1 is an exploded, diagramatic view of a preferred embodiment of an apparatus for aligning a housing with a rotating member constructed in accordance with the teachings of the present invention.
- FIG. 2 is a perspective view of the apparatus of FIG. 1 mounted to the engine crankshaft of a diesel engine.

hole 14 at one end for a purpose set out below and a threadedstud 16 at the other end. In an alternative embodiment, themain shaft 12 is provided with a flange (not shown) for stabilizing the shaft when the threadedstud 16 is screwed into the mount to theengine crankshaft 24 and theshaft 12 is provided with wrench flats, a knurled surface (neither of which is shown in FIG. 1), or other structure for facilitating the tightening of theshaft 12 to the mount. The mount takes the form of aplate 20 having a plurality ofholes 22 therethrough, theholes 22 being arranged onplate 20 to coincide with the locations of the holes (not visible in the figures) in anengine crankshaft 24. Each of theholes 22 is preferably tapered for receiving a corresponding bevel-headed bolt 26 so that theplate 20 is self-aligning with the center axis of the rotatingcrankshaft 24.Plate 20 is also provided with a threadedhole 28 at the center axis thereof for receiving the threadedstud 16 ofmain shaft 12, thereby aligning the longitudinal axis of themain shaft 12 with the center axis ofcrankshaft 24. - The alignment apparatus10 also comprises a
sleeve 30 received on and sized to fit closely overmain shaft 12. Although not required for the function of the present invention, atension bolt 32 is preferably threaded into the above-describedhole 14 in themain shaft 12 for retaining thesleeve 30 onmain shaft 12. When retained onmain shaft 12 in this manner, sleeve 30 rotates, or turns, relative tomain shaft 12. Atension washer 34 may be provided for frictionally engaging the end ofsleeve 30 to resist undesired rotation of the sleeve relative tomain shaft 12. -
Sleeve 30 is provided with a mount, indicated generally atreference numeral 36, for a dial indicator 38. In the presently preferred embodiment shown in the figures,mount 36 comprises a threadednipple 40 integrally formed withsleeve 30. Nipple 40 receives thethreads 42 of a dial indicator stand 44 to which amounting rod 46 is mounted by a swivel joint with athumbscrew 47 of a type known in the art. Thegauge 48 andcontact point 50 of dial indicator 38 are likewise mounted to mountingrod 46 by a swivel joint andthumbscrew 47. - As best shown in FIG. 2, to use the alignment apparatus10, the
