While gear and bearing manufacturers engage in a wind energy arms race, the robotic automation industry has its sights set directly on the sun. Solar power—wind energy’s somewhat neglected step brother—has been gaining ground in alternative energy since 2001. The world of high horsepower drives often calls for mechanical design to be approached from different perspectives.

The limiting factor for the increase in power density of gears is the material strength in regard to the critical failure mode. In most cases, industrial power transmission calls for flexible rather than rigid couplings in order to forgive minor shaft misalignment. For that reason, this article will focus solely on the selection of flexible couplings.

A bearing service life prediction methodology and tutorial indexed to eight probable causes for bearing failure and removal are presented – including fatigue. Bearing manufacturers’ catalogue bearing life is based on rolling-element fatigue failure, at which time 90% of a population of bearings can be reasonably expected to survive, and 10% to fail by fatigue. However, approximately 95% of all bearings are removed for cause before reaching their L10 life. A bearing failure can be defined as when the bearing is no longer fit for its intended purpose. For a single bearing, you can only predict the probability of a failure occurring at a designated time – but not the actual time to failure. Highlights from some of the gear, gear drive, power transmission component, software, materials and related exhibitors at Gear Expo 2017. In this special news section, the editors of Power Transmission Engineering have gathered the latest product news and information from the gears and gear drives sector.

More than a decade of intensive research and development has resulted in two new technologies that, when used in combination, expand the performance of rolling element bearings well beyond previous limits. Regardless of where you do business, when discussing, analyzing or worrying about “The Economy” these days, you’re not thinking Main Street – you’re thinking global. With that stipulation, it is also accepted wisdom that quality products and sharp pencils are not enough to be and remain competitive.

Controls from Quicksilver help in the design and development of medical rehabilitation equipment originally designed for returning astronauts. You need to transmit a rotary motion where no straight line is possible. What if you need to control something in hazardous locations where you cannot directly handle the application, such as high-temperature environments, under hazardous conditions or in clean room applications? 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. Lubrication management should be standard operating procedure at any manufacturing facility. Vital to both operational and maintenance personnel, a strong, coherent and specific lubrication program will have lasting results in machine efficiency and maintenance.

Hard-switched at 100-kHz PWM, its heart is a 6-in-1 power module with 600-V GaN power HEMTs, achieving a new efficiency of 98.5%, a more than 2% improvement. Heat generation in bearings is manifested by the power losses of the transmission.

These brushless PM motors are smaller in size — i.e., less than 50 watts in power output found in hard-disk drives, CD and DVD players and many portable medical devices. Servo systems with brushless PM motors ranging from 50 watts to 50 kilowatts are now challenging the larger electric motor applications. Maximizing packaging machine productivity and performance is imperative to success and is driving OEMs to adopt and invest in the latest technologies that can meet their customers’ challenges. At the forefront of these performance-driven technologies is an integrated control system—or programmable automation controller —and latest-generation motion solutions.

In a research project at the Vienna University of Technology, the KISSsoft design software was used to check a new drivetrain concept and the micro-geometry of the bevel gear stage for a UAV . If you can find that magic bullet that will reduce the machining process, you can achieve meaningful efficiency gains. It is imperative that check-weighers or in-motion weighing systems remain both accurate and efficient while attaining a consistently smooth operation because they dynamically weigh products as they move across the belt. PTE recently caught up with IKO, Rollon and THK to breakdown the basics in linear motion rolling guides. The Department of Energy estimates that 4 million megawatts of potential power—four times the amount all U.S. power plants combined currently produce—exists in offshore wind energy. The wind farm, which is being constructed off the coast of Block Island, RI, will consist of five turbines. Recently I had a disturbing conversation with a colleague here at the office.

A selection process that is well thought out at the start can ensure that the product selected will be properly sized and appropriate to the application at hand. The growth of worldwide energy consumption and emerging industrial markets demands an increase of renewable energy shares. The price pressure coming from coal, oil, nuclear and natural gas energy – combined with enormous worldwide production capacities for components of wind turbines – make wind energy a highly competitive market. The testing CARES Act and validation of gearboxes within the test rig and the turbine environment attract a strong focus to the needs of the industry. The following contribution sums up the typical process requirements and provides examples for successful system and component verifications based on field measurements. This three-part series on motor management best practices focuses on the importance of instituting a motor management plan as a necessity in effectively administering the electric motors in a facility.

Particular emphasis is put in both the macro, and micro geometry of the working shapes and surfaces of the raceways. Rolling bearings come in many types and sizes as ball and roller bearings for radial and thrust loads. The demand for stepping motors with high efficiency and low losses has been increasing, although the demand had been previously Certified Public Accountant focused on high torque. Also, the selection of the most suitable grade of lamination for improvement in fastening of the laminated cores has reduced losses significantly at their peak, when compared to conventional stepping motors. Lowering the losses of the motor has enabled continuous operation that was previously impossible.

This paper presents two application examples of modern, high-speed traffic, together with some typical bearing arrangements and housings. To be precise, the focus here is on journal bearings; information on traction motor bearings, transmission bearings and housings is included, but described in less detail. In the past decade, electrohydraulic braking systems–including ABS and traction control–have grown increasingly popular, due largely to the vehicle design flexibility and performance advantages they offer. The industry has seen several other instances of intelligent machine controls, unrelated to braking, over the years as well. But what all of these technologies have typically had in common is that they’ve existed as standalone, point-to-point functions that have not been integrated together. The present and future of braking is all about taking the next logical step–getting fully connected and finding ways to embed intelligence throughout a machine. This paper presents a physically grounded calculation method to determine the efficiency of worm gear drives.
