Patent number: 6435817Abstract: A fan assembly includes a vibration damping system to reduce induced vibrational energy generated as a result of fan motor operation. The vibration damping system includes a plurality of arms and damping material. The vibration damping system arms extend between a fan motor housing and a shroud assembly disposed circumferentially outward from the fan motor housing. The damping material is attached to an end of each of the vibration damping system arms and connects each arm to the shroud assembly. The damping material absorbs induced vibrational energy generated by fan motor operation.Type: GrantFiled: June 20, 2000Date of Patent: August 20, 2002Assignee: General Electric CompanyInventors: Robert Keith Hollenbeck, James Everett Grimm, David L.

Patent number: 4726112Abstract: 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.Type: GrantFiled: October 28, 1986Date of Patent: February 23, 1988Assignee: General Electric CompanyInventors: James L.
