(SPONSORED CONTENT)Selecting and Sizing Electromechanical Screw Jacks to Replace Hydraulic Lifting Systems
There is a widespread push in North America to replace hydraulic lifting systems with electromechanical systems. This trend has been going on for many years in Europe and is now really taking hold in North America. Many engineers are now tasked with the job of eliminating environmentally unfriendly hydraulic oil with systems that are purely electromechanical. When making this changeover, a number of important factors need to be considered to make sure the new design will work properly, efficiently, and reliably over the life of the system. This webinar will walk you through the critical engineering factors that need to be considered and then will create a multi-jack lifting system complete with the performance data, 3D drawings and bills of materials.

A Look at Gear & Gear Drive Lubrication Performance Improvements
It is a simple fact: better lubrication can lead to dramatic energy savings and an improved bottom line. This ought to interest any plant manager who is looking for ways to reduce operating costs, and it is especially significant at a time when stricter government regulations are in direct contradiction to reducing costs. Lubrication reliability is the solution; this article will describe how manufacturing plants can use âœlubrication reliability best-practicesâ to reduce their energy consumption, emissions and operating costs—all at the same time.
Though the original definition of mechatronics derived from the Yasakawa Electric Company in the late 1960s (the company won trademark rights for the term in 1973), the word has remarkably evolved.
Engineers typically learn that the bearing L10 life can be estimated using the so called âœC/P methodâ â” or the âœbasic rating lifeâ of the bearing, a method rooted in the 1940s. Major developments have since led to the âœmodified rating life,â 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 â” 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 â” use of these improved calculation methods are not practiced by all engineers. Indeed â” many continue referring to the old model as a way of seeking compliance with existing, established practices.
When it comes to selecting a connecting element between a drive motor and a pump unit, engineers most often choose an elastomeric coupling because of its failure protection and its vibration damping capabilities. Elastomeric couplings, traditionally manufactured with metallic hubs, feature a rugged and robust design noted for its simplicity.
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.
Servo control system engineers typically work designing new systems or redesigning existing systems for conveyors, pick and place machines, gantries, machine tools or other equipment.
The SKF Generalized Bearing Life Model is (GBLM) an innovative new bearing rating life model that is designed to help engineers calculate bearing rating life in a more realistic manner. The new model is a major step forward for the industry and will play an important role in enabling OEMs and end users to better match bearings and applications, resulting in improved machine life and reduced operating costs.
Yes, the headline is correct: Autonomous vehicles are not a new idea. In fact, in the 1950s, handsfree driving so interested General Motors engineers that they designed a concept car for it. And in 1956, at its own auto show, the GM Motorama, the automaker unveiled the car, the Firebird II.
Power density is a key factor in gear design. Increasing the power density enables engineers to use smaller gears for their applications which lead to smaller and lighter gear boxes. The benefit for example for the automotive industry is less moving load in the vehicles and therefor a reduction of fuel consumption and subsequently a reduction of CO2 emission. The limiting factor for the increase in power density of gears is the material strength in regard to the critical failure mode.
Reliability and maintenance engineers can improve uptime and save money on both long-term maintenance and downtime costs by properly diagnosing and correcting bearing vibration issues when they exceed their acceptable limits. This requires inspecting the housing as well as the liner for wear, and replacing them as a pair when the housing is worn, so that wear-in between the mating surfaces can occur.
Engineers are often challenged with the seemingly impossible task of doing more with less. Customers want more power transmitted in a smaller space, they want more efficient designs, and, of course, they want to spend less money. So engineers are always looking for ways to squeeze the most out of their mechanical systems. Theyâ™re constantly working to maximize power density, increase energy efficiency and reduce costs to meet their customersâ™ needs.
Design engineers across industries rely on pillow block bearings for a variety of tough and unconventional applications. Having access to data that backs housing strength performance claims is an integral part of choosing the right bearing to keep operations running optimally. What design considerations must be made when the application demands a pillow block installation on a non-horizontal orientation? What happens when bearing load is not applied through the base of the unit? Timken answers these questions with physical testing, advanced modeling and real-world experience to facilitate the selection of pillow block bearings for specific applications.
For design engineers and purchasing agents alike, bearings can sometimes be like family. Oh, you know - can't live with 'em, canâ™t live without 'em.
Wheelie car competition helps develop future engineers.
While it is valid to state that energy efficiency is defined as the same level of production being achieved at an overall lower energy cost, it is equally important for todayâ™s machine builders and automation engineers alike to remember that an energy-efficient system can actually translate into higher productivity. This is achievable through a comprehensive approach to energy management.

Nowadays, you can find scientists and engineers creating micro-robotic creatures for a slew of fascinating research projects.
When comparing bearing suppliers, engineers are often left with few options other than to compare dynamic load ratings and corresponding life calculations. Of course, we can look at steel and manufacturing quality; but if we are comparing sources of similar quality, those items may not provide a large contrast. It often surprises people to learn that bearing capacities are calculated values, not tested values. Lately, however, a trend is emerging for bearing suppliers to increase their ratings for higher performance bearings that have premium features such as higher quality steel and specilaized heat treatment. Bearing companies are under intense competitive pressure to make every feature add to the dynamic capacity of their bearings because it is very well understood that an increase in capacity adds to the bottom line.

Performance is demonstrated by virtue of test bench results of seals made from MDI-, PPDI- and NDI-based materials.
Motion control systems engineers work chiefly in two well-defined areas: 1) new designs and 2) redesigns or retrofits. This article examines the best approach for each option.
Today, better fuel economy is a main objective in the automotive development process. It remains top-of-mind with the auto industry and consumers because of costs and environmental impacts. Because the industry’s average fuel-economy standard is required to increase by 40 percent by 2020, manufacturers and engineers are working to develop fuel-efficient, environmentally friendly and reliable designs for vehicles.
Electric motors are often considered a mature industryâ” one whose basic technology wasinvented more than a century ago and whose fundamental concepts havenâ™t changed much since. But new applications continue to demand change. Engineers want greater efficiency, more precise control and improved reliability.
