Considering the local flank parameters, such as pressure or transmission error, a significant influence of the load-dependent center distance can be observed. With the FVA-Workbench, the load-dependent center distance is always considered.
Try to gain as much advantage as possible when you do design reviews; they can result in greatly improved designs and can cut multiple iterations out of the process.
The industrial arts of mechanical engineering are all around us and seen in many forms and technologies. Of greatest interest is how these wonders are designed, constructed and used. From the smallest home appliance to the behemoths used for outsize building and excavation projects.
A discussion of the evolution of condition
monitoring for bearings and the upcoming
introduction of company's next-generation
condition monitoring platform.
Troubleshooting infrequent intermittent problems can be one of the most frustrating engineering areas. It is also a great opportunity to use system knowledge and all of your senses and sleuthing abilities.
Good machinery can last a lifetime. But, replacement parts for older equipment may be near impossible to find. So, what do you do when you're looking to replace hard-to-find bearings and related parts for older machines?
Energy efficiency is for more than just motors. Here are some mechatronics companies making sure you get more bang for your buck when it comes to your power bill.
Over the past several months, members of
our staff have traveled quite a bit, and we've had a lot of opportunities to gauge their confidence. And while nobody
is overwhelmingly enthusiastic - nobody has told us this is their best year ever - almost everyone seems at least content with the stability that slow and steady
growth provides.
In case you missed them, following are three recent blog postings by our popular PTE bearings blogger - Norm Parker. We also felt that, should you not be a blog follower, this would be a good way to introduce you to Norm's bearings wisdom. Parker is currently the global senior specialist/roller bearings at Fiat Chrysler Automobiles (FCA).
Here’s what we know about Tremont, Illinois: It’s a small village in Tazewell County, (population 2,400+), holds an annual summer turkey festival
(quite popular) and the courthouse is a famous historic site where politician James Shields challenged an “up-and-coming” lawyer named Abraham Lincoln to a duel with cavalry broad swords (they showed up, but the duel never materialized). In 2016, you can add FIRST Robotics Competition World Champion to the village’s rather eccentric list of accomplishments.
In this century’s complex, ever-
changing world of manufacturing,
such capabilities as hardware and software expertise, effective location and distribution, business savvy and
yes, even luck, are some of the
cardinal requirements for running
a successful business.
In 1941, the federal Aircraft Engine Research Laboratory set up shop in Cleveland, Ohio. This year, and several name changes later, what is now the NASA Glenn Research Center celebrates its 75th anniversary.
As part of the year-long festivities,
Glenn’s adjunct Lewis Field main campus will be open to the public May 21 and 22, and Plum Brook Station in Sandusky, Ohio will hold its open house June 11 and 12.
Energy’s
endless energy efficiency
game of whack-a-mole, motors have historically always been one of the go-to moles. They’ve been in the spotlight since 1992. Over the past few decades, repeated efficiency laws have seen motor efficiency get whacked into tighter and tighter shape.
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.
It seems preposterous in the whimsical, wireless world of today, but in 1977 cinema’s greatest visioneers came together and decided the pinnacle of robotic technology in the future would be a motorized trash can.
A wide variety of companies displayed mechanical power transmission and motion control technologies at Pack Expo, held in November in Chicago. The event, which is the largest packaging and processing trade show in North America, attracted more than 48,000 attendees, according to show owner and producer PMMI. The four-day event included 2,352 exhibiting companies, an increase of more than 19 percent from the previous show in 2012.
The 8th International CTI Symposium on Automotive Transmissions, HEV and EV Drives took place in Rochester, Michigan from May 12-15. The event kicked off with its popular introductory seminar "Basics and Practice of Automotive Transmissions."
Recently I had a disturbing conversation with a colleague here at the office. During the conversation, it became clear to me that my co-worker -- a really
intelligent guy whom I respect a lot -- had no idea how even the most simple electric motor works.
When it comes to gear design software, the learning curve never ends. The leading vendors offer various training programs to keep their users well-informed.
Seal design engineers and end users are continually seeking improved sealing
systems and materials. This paper describes the potential of a new thermoplastic polyurethane (TPU) material to deliver improvements in pressure, speed and temperature capability, which are presented as comparisons to proven industry
standard materials. Performance is demonstrated by virtue of test bench
results of seals made from MDI-, PPDI- and NDI-based materials.
Despite posting its slowest quarter
since early 2007, AWEA remains
optimistic that the wind industry can
and will work successfully with the
revolving doors in Washington.
The recent trend toward using segmented laminations as a means to increase slot fill and facilitate automated fabrication of electric machines comes with a penalty of increased core loss at the segment joints.
When a bearing is damaged, it is often removed from service and replaced before it reaches its full, useful and economical life. Advancements in bearing design, materials, bearing maintenance and repair methods have greatly improved the potential for and popularity of bearing repair as an effective way to extend the life of the bearing.
Th e Allen Telescope Array at Hat Creek, CA is a joint venture between the University of California Berkeley and the SETI Institute of Mountain View, CA. SETI has hired Minex Engineering of Antioch, CA to help with the design and installation of state-of-the-art drives and controls for the antenna array.
