Generator ball bearing support

摘要

A bearing support plate for use in a generator has a radially enlarged flange with a first cylindrical portion extending from the flange in one direction which will provide a bearing support for an outer race of a ball bearing, and a radially inner cylindrical portion extending in an opposed direction that will be away from the ball bearing relative to the flange. The flange is generally cylindrical but has a truncated portion over a circumferential extent. The first cylindrical portion is formed with radially enlarged portions with intermediate radially thinner portions. The flange includes bolt holes circumferentially aligned with the radially thinner portions.

1. A bearing support plate for use in a generator comprising:
a radially enlarged flange, a first cylindrical portion extending from the flange in one direction which will provide a bearing support for an outer race of a ball bearing, and a radially inner second cylindrical portion extending in an opposed direction that will be away from the ball bearing relative to the flange, said flange being generally cylindrical but having a truncated portion over a circumferential extent, and said first cylindrical portion being formed with radially enlarged portions and intermediate radially thinner portions, and said flange including bolt holes circumferentially aligned with said radially thinner portions; a ratio of an inner first radius of said first cylindrical portion to a second radius to the outer diameter of said first cylindrical portion at a radially thinner portion being between 0.88 and 0.89; and said flange extending for an axial distance along a center axis of said bearing support plate, and a ratio of said first radius to said axial distance is between 8.75 and 9.12.
