It occurred to me recently that my request for “origin stories” may not have been inclusive enough. As an engineer, I tend to focus on the technica...

New turnkey, "off-the-shelf" Gleason 2700AR system automates larger-gear load/unload to speed throughput, optimize process flow - and take the weight off the operator.

We’ll get back to our “origin story” project soon. One thing I have noticed about the guest blogs so far is that the people kept moving up the ladd...

Large bevel gears drive the crushing machines used to process ores and minerals in the hard-rock mining and aggregates industries. This paper is intended to help the reader understand the unique aspects of these machines, and why crushing applications fall outside the traditional automotive paradigm for bevel gears.

Historically, gearbox original equipment manufacturers (OEMs) and repair organizations have tended to offer their customers no-load, full speed (spin) tests as a standard performance test. If a load test was specified, the supplier would probably offer a locked torque back-to-back simulated load test, which requires a large investment in tooling to connect shafts of the test and slave gearboxes.

For this year’s exercise in large gears, we’re not going to dwell on size range or length, merely look at the fundamental challenges and latest technologies required to manufacture large parts in the gear industry. This could be a gearbox assembly for the construction, mining or oil and gas industries or simply a large standalone gear pinion set for a custom application. Whatever the industry or application, large gears require more preparation, planning and precision than other areas of gear manufacturing.

Spur gears have been around “forever.” That ancient astronomical device recovered from the Mediterranean Sea a few years ago shows the antiquity an...

Business is finally starting to get back to usual in the big gear world, which offers us a chance to look back at the greatest lesson on how to survive an economic downturn. Includes the sidebar: "Brass Tacks with Klingelnberg."

Moving required getting rid of lots of books. My much better half is also a reader and we made about a dozen trips to the resale shop to put our su...

A question came to me recently in an e-mail that I could not answer from memory. It seemed like something I had read in a book once so the long-del...
