Bearings Education - A Lot to Learn

June 1, 2013
Jack McGuinn
Bearings ain't beanbag. They are complicated. They are big-business. They are often counterfeited. They are used in virtually anything that moves. But it is the "complicated" part that challenges OEMs, job shops and other operations, and, most of all, their employees. Add to that the countless other entities around the world that are intimately involved with bearings and you can arrive at a semblance of an idea of just how important these precious orbs can be to a successful operation.

Analysis of Load Distribution in Planet Gear Bearings

September 1, 2011
In epicyclic gear sets designed for aeronautical applications, planet gears are generally supported by spherical roller bearings with the bearing outer race integral to the gear hub. This article presents a new method to compute roller load distribution in such bearings where the outer ring can’t be considered rigid.

Comparing Surface Failure Modes in Bearings and Gears: Appearances vs. Mechanisms

July 1, 1992
In the 1960's and early 1970's, considerable work was done to identify the various modes of damage that ended the lives of rolling element bearings. A simple summary of all the damage modes that could lead to failure is given in Table 1. In bearing applications that have insufficient or improper lubricant, or have contaminants (water, solid particles) or poor sealing, failure, such as excessive wear or vibration or corrosion, may occur, rather than contact fatigue. Usually other components in the overall system besides bearings also suffer. Over the years, builders of transmissions, axles, and gear boxes that comprise such systems have understood the need to improve the operating environment within such units, so that some system life improvements have taken place.
