Embodiment Construction

[0028] The terms “comprise” (and any form of comprise, such as “comprises” and “comprising”), “have” (and any form of have, such as “has” and “having”), and “include” (and any form of include, such as “includes” and “including”) are open-ended linking verbs. As a result, a device or method that “comprises,”“has,” or “includes” one or more elements or steps possesses those one or more elements or steps, but is not limited to possessing only those one or more elements. Likewise, an element of a device or a step 25791831.1 of a method that “comprises,”“has,” or “includes” one or more features possesses those one or more features, but is not limited to possessing only those one or more features.

[0029] Thus, and by way of example, a load-balancing device “comprising” a shaft engagement element configured to engage an end of a shaft; a bearing bracket engagement element configured to engage a bearing bracket; and a connector element connecting the shaft engagement element to the bearing ...

Abstract

Load-balancing and bearing removal devices useful in removing bearings, such as rolling element bearings, for rotating machine maintenance and replacement. Insulation assemblies useful with bearing assemblies that fit in openings in bearing brackets of rotating machines, such as large synchronous motors or generators.

Description

CROSS-REFERENCES TO RELATED APPLICATION(S) [0001] This is a divisional of co-pending application Ser. No. 10 / 841,209, filed May 7, 2004.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The invention relates generally to the field of rotating machines, such as motors and generators. More particularly, it relates to bearing assemblies used with such machines and devices useful when removing the bearing assemblies. [0004] 2. Description of Related Art [0005] Rolling element bearings, also known as anti-friction bearings, are widely used on many types of rotating machinery and have a limited life span. That life span can be reduced by misuse and adverse operating conditions. Bearing removal is frequently required in the field as part of the rotating machinery's maintenance. [0006] Traditionally, bearing assemblies have been designed such that the removal of the bearing requires the removal of the entire bearing bracket that houses the bearing and that is mounted to th...
