Rosetta Mission mixes with Maxon, Kim K for one unforgettable photo

The first thing you see when you walk into Winzeler Gear is a pretty face. No, scratch that — the face is beautiful. Streamlined with chiseled cheek bones, delicate yet bold and strong, a half dozen photos of the feminine face line the building’s entranceway, enclosed tastefully in simple black picture frames, beckoning you to come further in with its pleasant warmth, repelling you to turn and leave with its foreign presence in such a location.

Previously we discussed how to determine your cup interference fit based on thermal expectations. Then we discussed how the bearing cup contracts a...

A four-point contact ball bearing makes it easy to simplify machine designs that combine radial, thrust and moment loads, because it can handle all three simultaneously. They are primarily used for slow-to-moderate-speed applications, or where oscillatory movement is predominant.

Engineers typically learn that the bearing L10 life can be estimated using the so called “C/P method” — or the “basic rating life” of the bearing, a method rooted in the 1940s. Major developments have since led to the “modified rating life,” released in ISO 281:2007, which includes the aiso life modification factor. In this paper a succession of equations used for bearing life ratings are reviewed, and current bearing life rating practices are discussed in detail. It is shown that — despite the introduction more than 30 years ago of the adjustment factor of the basic rating life, and the standardization in 2007 of the aiso modification factor — use of these improved calculation methods are not practiced by all engineers. Indeed — many continue referring to the old model as a way of seeking compliance with existing, established practices.

Bellows couplings first began to be widely used by machine tool builders in the mid-to-late 20th century. With the advent of CNC technology, machine engineers started looking to improve upon some of the negative influences traditional power transmission couplings can have on a precision rotary / linear motion system.

Regarding 3-D printing of gears and machine tools, etc. — does plastic gearing have a future in 3-D printing/additive manufacturing?

John Morehead, national sales manager of Crouzet Motors (Vista, CA), was bunkered down in his office in Palatine, IL surrounded at all points by ankle-deep snow from an unfortunately terrible Chicago’s winter night.

The next step in our aluminum housing series is to determine where the cup interference is going. If we press a cup with 100µm interference into a ...
