Changing Entertainment Experiences with Electro-Mechanical Screw Jacks

There has been a significant shift in the Entertainment Industry to move away from manual and hydraulic operated systems to electro-mechanical screw jacks. The key reasons are safety, cleanliness, sound and reliability.

Providing the ultimate entertainment experience dates back to the Colosseum days, where lifts and trap doors were all part of making people, animals and staging all of a sudden appear. The Entertainment Industry still uses these techniques today, but how they operate has changed dramatically in recent years by using electro-mechanical screw jacks. White Paper Courtesy of DieQua

1 ISO-AGMA Standards: Specific Sliding Defined (March 2017)

Does the definition of specific sliding mean the same between ISO 21771:2007 and AGMA 917-B97? In ISO, specific sliding is the ratio of the sliding speed to the speed of a transverse profile in the direction of the tangent to the profile. In AGMA, specific sliding is ratio of gear tooth sliding velocity to its rolling velocity.

2 Computing Gear Sliding Losses (February 2020)

As concerns surrounding the environmental impact of fossil fuels continue to grow, so does the need to produce vehicles with higher overall efficiency. The importance of enhanced vehicles has spurred drivetrain component manufacturers to study every aspect of efficiency loss in their products. The gearbox is a key contributor to the overall drivetrain efficiency.

6 Eight Reasons to Use Air Bearings Over Mechanical Bearings (December 2016)

Mechanical guiding systems, such as crossedroller bearings, work well for most motion control applications; however, when precision, angular repeatability, and geometric performance (runout, straightness) are critical or where submicron bearing rumble is problematic, air bearings are recommended. An air-bearing stage is a rotary or linear positioner that floats on a cushion of air, using one of several preload mechanisms, nearly eliminating mechanical contact and thus wear, friction, and hysteresis effects. Here are eight reasons why an air-bearing stage might be the right choice for your application:

7 Bearing Lubricant Solution (December 2016)

A Chicago-area bakery was replacing the tray support bearings in its ovens on a reactionary basis. Their weekly inspection cycle was resulting in two mechanics spending an average of 20 labor hours per week to replace failed bearings. The premature bearing failures were caused by a combination of the high heat and humidity in the ovens, resulting in lubrication failure and contamination. When BDI was asked to recommend a solution, the bakery was averaging one month of bearing life in this application.

10 Electric Bikes - Wired for Fun (August 2020)

There is absolutely no doubt that riding an electric bicycle will not stir up cinematic memories of Marlon Brando (The Wild One) or Steve McQueen (The Great Escape) tearing it up on their hogs. Think more Pee Wee Herman and his Great Adventure.

11 Efficiency and Heat Balance Calculation of Worm Gears (December 2020)

If torque conversion with high gear ratio, compact installation space and 90-degree axis-crossing angle is needed, often worm gears are used. Due to their high power density and sliding speeds within the tooth contact, frictional heat and thermal stresses are higher compared to helical, bevel and hypoid gears, and thus the thermal load capacity of worm gears is lower.

12 Engineering Showcase 2015 (March 2015)

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.

13 Combining Gear Design with Manufacturing Process Decisions (June 2020)

The integration of manufacturing information into gear design software reduces cost during the design process by avoiding time-consuming back and forth between the design and manufacturing departments. The challenging task for such software is ensuring the design engineer does not need specific manufacturing expertise. Otherwise he or she would be overwhelmed and not use such a feature.

14 Monitoring the Health of Plant Machinery (September 2018)

Health monitoring or condition monitoring has been used for many years on machines and in plants where the cost of an outage is high. It allows failures to be anticipated and maintenance or repairs to be scheduled for the least loss of production, as well as avoiding unnecessary periodic maintenance.

15 Musical Gearboxes (October 2013)

Dave Soma, the mechanical supervisor at Leland Olds Station, a coal-fired power plant near Stanton, North Dakota, says he and his maintenance team care deeply about keeping the plant running and providing people electricity, especially in the dead of winter.

16 Run Like the Wind - Windpower Conference Heads to Chicago (April 2009)

Wind is the talk of the town. It has become especially relevant to the power transmission community where bearings, gears, couplings, motors and gearboxes are providing the equipment for this thriving alternative energy industry. It comes as no surprise that the Windpower 2009 Conference and Exhibition, arriving in Chicago from May 4–7, will be the largest gathering of wind energy professionals and technologies to date.

17 Historic Danish Theatre Gets a Facelift (April 2009)

The Royal Danish Theatre has occupied the heart of Copenhagen for centuries and recently upgraded to a new control system featuring Sprint Electric DC drives to extend the lives of the existing motors, keeping replacement costs down. The Swedish stage design and technology company Visual Act retained most of the original motors and mechanics while providing a much-needed facelift to the stage.

19 Intermetallic Nickel-Titanium Alloys for Oil-Lubricated Bearing Applications (August 2009)

Nitinol 60 (60NiTi), an intermetallic nickel-titanium alloy containing 60 wt % nickel and 40 wt % titanium, is shown to be a promising material for oil-lubricated, rolling and sliding contact applications such as bearings and gears.

20 Soft Starters vs. Variable Speed - Or Both (June 2011)

Given that many different hydraulic systems recommend the use of either frequency converters or cyclic control (soft starter technologies), the question must be asked - Which one of these solutions is the most cost-effective in reducing energy consumption and providing the most satisfactory payback time?

High-speed transit system the dreamwork of ideators or idiots?

22 Application of Ceramics to NU-Type Cylindrical Roller Bearings for Machine Tool Main Spindles (December 2011)

Bearings used to support main spindles on machine tools must be capable of higher speed and greater rigidity. This is true in that any main spindle that turns together with a tool or work piece mounted onto it is one of the critical machine tool components that directly affects machining efficiency and accuracy of the machine tool; and, the bearings that support the main spindle are the most critical machine elements on the machine tool.

23 How to Spec a Mill Gear (February 2014)

This paper outlines the design considerations that go into construction of a drive system in order to explain the importance of specific data, why it is required, and where design freedom is necessary. Apart from loads and speeds, interface dimensions and site specific conditions are also needed. Deciding up front which gear rating practice to select can affect the torque capacity of the drive train by ~15%.
