Highlights from some of the gear, gear drive, power transmission component, software, materials and related exhibitors at Gear Expo 2017.

Most of you who read this magazine have a close relationship with gears and gear drives. According to our surveys, 75% of you recommend, specify or buy them. It's a shame, then, that the majority of you will miss Gear Expo (Oct. 24-26 in Columbus, OH) this year.

A bearing service life prediction methodology and tutorial indexed to eight probable causes for bearing failure and removal are presented - including fatigue. Bearing life is probabilistic and not deterministic. Bearing manufacturers' catalogue (L10) bearing life is based on rolling-element fatigue failure, at which time 90% of a population of bearings can be reasonably expected to survive, and 10% to fail by fatigue. However, approximately 95% of all bearings are removed for cause before reaching their L10 life. A bearing failure can be defined as when the bearing is no longer fit for its intended purpose. For a single bearing, you can only predict the probability of a failure occurring at a designated time - but not the actual time to failure.

A reader is looking for the best reference materials with formulas for gear measurements over pins.

A good deal of confusion exists regarding the factors that determine an industrial electric bill. The following information is presented to help sort out the various items on which billing is based, and to offer suggestions on measures to help control and reduce electric utility bills.
