Abstract
A method of assembling a dynamoelectric machine. The dynamoelectric machine includes at least one end frame having a hub portion extending therefrom, and a cushioning device. The cushioning device has a pair of generally annular cylindric mounts associated generally concentrically with one of the mounts having an axial length greater than that of the other of the mounts, and a resilient material is interconnected between the mounts. In practicing this method, a part of the one mount is mounted in engagement about the hub, and thereby the other mount is disposed in a preselected position axially beyond the hub portion of the at least one end frame.

A method of assembling a dynamoelectric machine, the dynamoelectric machine having at least one end frame with a hub portion extending generally axially therefrom, and a cushioning device, including a pair of generally annular cylindric mounts arranged generally concentrically with each other with one of the mounts having an axial length predeterminately greater than the other of the mounts, and a resilient material disposed at least in part between the mounts, the method comprising the steps of:
- associating a part of the one mount of the cushioning device in mounting engagement about the hub portion of the at least one end frame generally along the axial extent of the hub portion and extending thereby the cushioning device generally axially from the at least one end frame;
- and
- positioning the other mount generally in a preselected location axially beyond the hub portion of the at least one end frame in response to the associating and extending step.
A method of assembling a dynamoelectric machine, the dynamoelectric machine including at least one end frame with a hub portion extending generally axially therefrom, a cushion device, and the cushioning device including a pair of generally annular cylindric mounts one of the mounts being generally concentrically disposed about the other of the mounts at least adjacent a free end portion thereof and being predeterminately axially spaced from another end portion of the other mount opposite the free end portion thereof, and a resilient material disposed at least in part between the concentrically arranged mounts, the method comprising the steps of:
- pressing the another end of the other mount into mounting engagement about the hub on the at least one end frame and disposing the another end of the other mount at least adjacent a part of the at least one end frame extending generally radially about the juncture of the at least one end frame part with the hub portion;
- and
- extending the cushioning device generally axially from the at least one end frame and arranging the one mount in a preselected position axially spaced beyond the hub portion of the at least one end frame in response to the pressing and disposing step.
A method of assembling a dynamoelectric machine, the dynamoelectric machine including a stationary assembly having a pair of opposite end frames with a pair of integral hub portions extending generally axially therefrom and with a pair of at least partial spherical bearing surfaces on the opposite end frames spaced generally axially beyond the hub portions thereof, respectively, a means for supporting at least the stationary assembly with the supporting means having a pair of axially spaced apart mounting sections, and a pair of devices for cushioning in engagement between the supporting means and the stationary assembly and with each cushioning device including a pair of generally annular cylindric mounts each having a pair of opposite end portions defining the axial length thereof with the axial length of one of the mounts being predeterminately greater than that of the other of the mounts and with the other mount being arranged generally concentrically about the one mount at least adjacent one of the opposite end portions thereof, a generally axial seating surface on the other mount extending at least in part generally circumferentially thereabout, and a resilient material interconnected between the mounts in the generally concentric arrangement thereof, respectively, the method comprising the steps of:
- receiving the hub portions of the opposite end frames in engagement within the other opposite end portions of the one mounts and extending thereby the cushioning devices generally axially from the opposite end frames, respectively;
- disposing the others generally in preselected positions spaced axially beyond the hub portions of the opposite end frames and locating a pair of imaginary planes extending along the centerlines of the seating surfaces on the other mounts and perpendicular to the axial lengths thereof at least closely adjacent another pair of imaginary planes extending perpendicular to the centerline axes of the at least partial spherical bearing surfaces on the opposite end frames and intersecting the at least partial spherical bearing surfaces at least generally adjacent the midsections thereof in response to the receiving and extending step and with the first named and another imaginary planes being generally parallel to each other, respectively;
- and
- seating the seating surface on the other mounts in engagement with at least a part of the mounting sections of the supporting means and aligning the at least parts of the mounting sections generally axially about the centerlines of the seating surfaces with the mounting sections extending at least in part in the first named imaginary planes, respectively.
