My initial skepticism about 3-D printing’s place in the gear industry took a solid hit during a recent visit to a client. I am used to seeing color...

A popular cable car customizing show recently featured a segment on using 3-D printing to produce a prototype part. There wasn’t anything original ...

A friend of mine is the inspection department for a custom machine shop. He is also the process engineer and, occasionally, a machine operator. Rec...

Due to increasing requirements regarding the vibrational behavior of automotive transmissions, it is necessary to develop reliable methods for noise evaluation and design optimization. Continuous research led to the development of an elaborate method for gear noise evaluation. The presented methodology enables the gear engineer to optimize the microgeometry with respect to robust manufacturing.

My last post discussed reviewing the ratings and designs of “legacy products,” those venerable parts and gearboxes still being ordered twenty, thir...

One of the first things you hear upon becoming a parent is that “children keep you young.” Once, I foolishly thought this referred to your physical...

Helical gear teeth are affected by cratering wear — particularly in the regions of low oil film thicknesses, high flank pressures and high sliding speeds. The greatest wear occurs on the pinion — in the area of negative specific sliding. Here the tooth tip radius of the driven gear makes contact with the flank of the driving gear with maximum sliding speed and pressure.

[starbox]How long should gear manufacturing equipment last? I posted before about some very “veteran” gear cutting machines that are still earning ...
