Kids Love Technology

Kate, a sophomore studying engineering at the University of Wisconsin-Platteville, has a genuine interest in manufacturing, so it was natural that she attend IMTS. But the other three? My kids? Well, let’s just say that their interests lie elsewhere. Matt, also a sophomore, is studying business at UW-Platteville. Emily, a sophomore in high school, wants to join the Peace Corps. Renee, an eighth grader, wants to be a surgeon.

ISO 281:2007 - Caveat Emptor

I was invited by Tom Astrene of TLT to write a response to the July 2010 TLT article (Ref. 1). My rebuttal — “In Search of a Fatigue Limit: A Critique of ISO Standard 281:2007” — was published in Tribology and Lubrication Engineering, TLT, August 2010 edition (Ref. 10). While this article is also available online, I will attempt to summarize the essence of my response.

How Does An Electric Motor Work

If you’re an electrical engineer you know how an electric motor works; if you aren’t, it can be extremely confusing. Therefore, here’s the simplified explanation (or the “how an electric motor works for dummies” version) of how a four-pole, three-phase AC induction motor works in a car.

Taking Aim at Conveyor Systems

It's no secret that conveyor systems are the primary market for gearmotors, and so it shouldn't be much of a surprise that gearmotor manufacturers are looking for ways to cater to that market's needs. From Brother's new VFDs to Siemens' Simotics S-1FG1, a lot of the new solutions in the industry have their own unique quirks, but all fall into a few common veins.

Pack Expo 2016

Pack Expo takes place November 6-9 at McCormick Place in Chicago. With 2,100 exhibitors, it’s the world’s largest most comprehensive processing and packaging trade show in 2016.

Ceramic Bearings for Water Processing, Water Filtration and Liquid Handling Applications

Bearings are an essential component in the majority of mechanical designs and equipment. It is important to consider the most effective materials when designing industrial machinery, especially in applications where water or other liquids are present. Many materials will be unable to overcome the challenges associated with operating in a wet or corrosive environment.

Guidelines for Bearing Seals

Equipment downtime and reduced component life are a few of the consequences — and potential costs — of using the wrong seals on many types of industrial equipment including pump bearing frames, electric motors, fans, pillow blocks, gearboxes and more. However, if correctly specified and installed, seals provide effective barriers that both retain lubricants as well as protect against water, corrosion, debris and other contaminants.

Determining Diametral Pitch, Center Distance

I need help determining the diametral pitch needed to achieve the closest center-to-center distance for 2 spur gears. The 1st gear is a 34-tooth and the 2nd gear is a 28-tooth. The center-to-center distance between the gears needs to be as close to 2 1/8" as possible.

Making Shakespeare Shine

New things are invented for theater lighting all the time and they’re usually big, expensive technology-driven devices. It’s the simple things that make you wonder, “Why didn’t I think of that?” according to Ken Billington, lighting designer. The RSC Lightlock is a great example of this.
