How to Ensure Reliable Performance, Increased Efficiency and Lowest Total Cost of Ownership.
Standing in a factory or a warehouse, you're bound to notice machinery, whether it's a conveyor system that winds across the floor or large fans that hang from the ceiling. You may even notice automated guided vehicles or autonomous mobile robots carrying parts, driving themselves from one section of the building to another. These machines are good candidates for using high-efficiency gearmotors, especially if they're expected to run for long stretches at a time. If they aren't using high-efficiency gearmotors, then they may be costing more money than they should.
The following article explains the commonly used paint components and methods within the gearmotor industry, with a focus on electrodeposition coating (E-Coat). These processes will be described in general, with a closer examination of the E-Coat applications steps. Some pros and cons of each method will be presented along with comparative test results showing the benefits of E-Coat.
Gearmotors handle harsh environments with digitalization, customization and improved service life.

With AGVs, a primary bottleneck on productivity is battery life. But when looking at an AGV as a full system, there are plenty of ways this bottleneck can be widened.
Automate Show Examines the Integration of Robotics, Automation and Machine Vision, while Promat explores the latest in material handling technology.
Rolling element bearings are widely used in mechanical transmission to reduce friction between two rotating parts. With the further development of the electrical motor in mechanical industry, REBs operate more and more at high rotational speed. For these applications, REBs power losses can be predominant in mechanical transmissions.
These exhibitors want you to know they're making a splash at MPT Expo 2019.
With the increasing mechanical power capacity of gearboxes, the thermal power limit tends to become the limiting factor. To achieve a balanced system, the gear unit needs extra cooling. Using a fan that is mounted to a fast rotating shaft is a common solution. For this solution an optimal design is investigated.

Implementing a predictive maintenance (PM) program can be tough. Despite its proven success, many companies have been operating the same way for over 50 years and donâ™t know where to start. Understanding where to start and where to focus is critical. The intention of this article is to give insight to start and sustain an effective program using todayâ™s technology and devices.
Fans of Arthur C. Clarke may remember a concept in his 1979 novel, The Fountains of Paradise, of an orbital elevator used to raise payloads from the ground to a satellite as a more cost-effective means of transporting material to outer space.
"Restless Planet" transports guests to a Jurassic landscape with more than 100 animatronic dinosaurs.
With Pack Expo Las Vegas around the corner, we took a look at the state of the packaging industry today to see what you can expect at the show. The answer is more automation.
If there are two things that are in tight supply in the industry, it's time and talent. Manufacturers are always pressured to do more faster, and the industry is producing fewer experts to help them do it, so the industry's had to get crafty and find what time-cutting procedures they can.
Th e primary sources of bearing failure are lack of lubrication and contaminant ingress. Industrial sealing devices are the primary protection against bearing failure. When the sealing device fails, bearing failure is imminent. Th erefore, extending the life of sealing devices extends bearing life and in turn improves equipment uptime.

One of the best things about being a journalist â” whether for example it be reporting on manufacturing, politics, show business, or anything else â” is being paid to âœgo to schoolâ and learning about any number of things that you were perhaps ignorant of at the outset.
One of our goals at Power Transmission Engineering is to help you understand, identify and select the best technology for your mechanical power transmission or motion control applications. With every project, you have to decide which components to use, and which suppliers, based on functionality, quality and price. We aim to help you make those decisions informed by providing the latest information on current technology, especially when it comes to mechanical components.
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.
News From the gear Industry
The secondhand on the Doomsday dial ominously spins around the face, slowly but ever so surely inching the motor industry towards its inevitable terminus:
Gear drives deliver power to industrial equipment such as bulk material conveyors, mixers, pumps and paper mills. The reliability that translates into greater uptime and profitability begins by specifying and selecting the proper drives for these critical applications.
A new solution has been developed around the use of microprocessor-controlled prostheses. Just like natural limbs, these can react automatically, adapting to the current situation.
Following is a presentation of a gear design based upon a theoretically perfect gear technology, for which an overview is offered for consideration. What follows is a report on the design's testing and subsequent manufacture of a hypoid gear pair for a 1999 Ford Mustang.
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.
When talking about high-end machining or manufacturing applications that include direct-drive technology, one of the key advantages of utilizing this particular transmission method is its endurance. Because of the very nature of direct-drive motors they are able to operate at peak performance levels indefinitely â” without any kind of wear or aging â” as long as the motor isnâ™t pushed past its capacity. Unfortunately, because this isnâ™t a perfect world, unexpected things can happen which can cause the motor to overheat. Whether the heat source is due to a parameter being input incorrectly, or an unexpected external force causing more resistance than expected â” it is important to have certain forms of thermal protection in place. Since torque motors are built in such a way that they cannot be repaired and yet maintain their efficiency, it is vital to prevent any overheating â” thus precluding the need to purchase a new one.
