Unless you are involved with rebuilding old equipment, it may be entirely possible to never see a tooth flank with “progressive pitting.”...

This paper outlines the comparison of efficiencies for worm gearboxes with a center distance ranging from 28 - 150 mm that have single reduction from 5 to 100:1. Efficiencies are calculated using several standards (AGMA, ISO, DIN, BS) or by methods defined in other bibliographic references. It also deals with the measurement of torque and temperature on a test rig — required for the calibration of an analytical model to predict worm gearbox efficiency and temperature. And finally, there are examples of experimental activity (wear and friction measurements on a blockon- ring tribometer and the measurements of dynamic viscosity) regarding the effort of improving the efficiency for worm gear drivers by adding nanoparticles of fullerene shape to standard PEG lubricant

There have been a few times in my life when I wished I could turn off my internal engineer and just be a regular guy. If you ask my wife she could ...

News from around the Gear Industry

Plastic gears are everywhere today - throughout your car, at the oceans' lowest depths, in deep space. The question, when is a metal gear a candidate for plastic conversion, can be addressed in three words, i.e. what's the application?

There exists an ongoing, urgent need for a rating method to assess micropitting risk, as AGMA considers it a "a very significant failure mode for rolling element bearings and gear teeth - especially in gearbox applications such as wind turbines."

    Growing up in Milwaukee I learned about cold weather early and got a refresher course every winter. These lessons served me wel...

Recently, an attorney told me that his eleven-year-old daughter had “discovered” gears in a science class and was excitedly learning all she could ...
