Sometimes I feel like I blink and another year is gone. By the time most of you read this, it will be at or near the end of 2015. If you’re like us, you’ll be reflecting on the past year and looking forward to the next.

I’m building a custom gearbox with 7075 T-6 spur gears, and I’m concerned
that aluminum flakes will enter the races on the roller bearings (SKF 2307) and cause premature failure. So my question is — should I place an oil seal on the shaft first to protect the bearing — or is this an unfounded concern and I should mount the seal in the typical manner outside the bearing? Or both? Or go with a sealed bearing? I’m confused and could use your expertise, please.
One of the great benefits of Gear Expo for us here at Gear Technology is the opportunity to meet faceto-face with many of the people who, in one way
or another, contribute to our success throughout the year. After all, our success is dependent almost entirely
on information and the people who provide it. These contributors
include researchers at top technical universities, the heads of technology at major gear industry corporations, independent consultants with decades of gear industry experience, members
and volunteers at leading industry organizations like the AGMA,
our technical editors and others.
Reducing losses and increasing profits by instituting a motor management plan is what this series of articles is all about. Here in Part I, we discuss how to create a motor inventory and establish repair-or-replace motor guidelines. Subsequent topics in this
three-part series will address (Part II)
motor failure policies and purchasing
specifications, and (Part III) repair
specifications and preventive and predictive maintenance, respectively.

This issue we take a long, hard look at motor efficiency, and you should, too. After all, electric motors used in industrial settings are the single largest consumer of electricity in the United States. Upgrading your electric motors is not only good for the environment, but it’s
also good for your bottom line. Sure, saving electricity lessens
the burden on our country’s energy infrastructure. But it
also saves you money in the long run.
Is there a gear software package out there that will calculate the design of spur, helical, worm, and planetary gearsets? Also, we would like a program that calculates stresses and material selection. Finally, we would like to have the program calculate bearings loads, too. Thank you for your help.

If only there were some source of endless knowledge, experience
and wisdom to guide you through your gear-related problems.
If only there were some philosopher on a mountaintop
whose sole purpose was to bring enlightenment to your gear noise problems, to unravel the mysteries of profile shift, to provide insight to a critical gear manufacturing problem or to explain the meaning of life (gear life, that is).
Gear Expo 2015 takes place October 20–22 in Detroit. If you haven’t already made plans to attend the show, you might be might be missing out on a great chance to learn more about gears, find new potential suppliers and network with your peers.
