How to specify a ball screw

Powertransmissions - How to specify a ball screwBall screws are available in a range of types, styles, and sizes. A few tips, though, will help you match the right ball screw with the right application.

1. You will have the best success with specifying a ball screw if you know the following information about your application:

Duty Cycle—the cycle rate, dwell times, and lifetime expectation.

Environment—harsh or rugged, wash down, heat extremes, or other requirements.

Load—the mass being moved.

Orientation—how the ball screw be mounted (vertically or horizontally).

Precision—what is the positional accuracy and repeatability need to be.

Speed—velocity and acceleration requirements.

Travel—stroke length.

2. Consider a preloaded ball screw

Preloading Ball Screw 300x292

Ball screw manufacturers can increase the rigidity of the ball screw through preloading—a step that reduces axial clearance between the ball nut and the screw shaft. In addition, preloading enhances positioning precision and repeatability. One of the more common preload options is the use of oversized balls. But other methods include the use of a double-nut. Manufacturers may also offset the raceway spiral, which can force the balls into a preload condition.

3. Know your need for speed

Manufacturers offer information on the operational speed limits that their ball screw system can handle. Variables that go into this determination include temperature, operating limits of the bearing and inertia of the bearing’s moving components.

The critical speed of a ball screw is the lowest speed at which the ball screw shaft is in resonance, i.e. where screw whip occurs. It depends on screw length and the end bearing mounting support. To prevent critical speed, select a larger screw diameter, choose the right bearings, and use proper screw supports.

Formulas to help determine critical speed

4. And of course, the next tip is to always use a good lubricant. Oil and grease are the common choices. Avoid ones with solid additives as they can clog the recirculating system.

SKF WAVE seal generates up to 35% less heat

Powertransmissions - SKF WAVE seal generates up to 35 Percent less heat

SKF, the knowledge engineering company, has launched the SKF WAVE seal, a low friction shaft sealing solution that boosts sustainability and minimises failure in a range of applications. The innovation is one of many recent advances from SKF that combine increased efficiency with enhanced performance.
The SKF WAVE seal achieves these improvements through a specially moulded lip that forms a wave pattern around the shaft surface, pumping lubricant back to the bearing, while pushing contamination away, regardless which way the shaft is turning. The specially designed lip extends seal lifespan by generating up to 35% less heat at the contact point, reducing incidents of premature seal failure caused by heat, blistering, hardening or lubricant breakdown. The SKF WAVE seal also creates 20% less friction torque, and provides greater lip lubrication than standard lip versions, offering a more environmentally-friendly sealing solution on many levels.
The seal is suitable for a wide variety of applications, including gearboxes, speed reducers, transmissions, motors, drive systems and pumps. To enable the maximum number of users and applications to benefit from the SKF WAVE seal, versions are available with a pressure profile for applications where pressure differential across the seal is higher than normal.
The SKF WAVE seal can be supplied in nitrile or fluoro rubber to fit shaft diameters from 12 to 280mm. A non-hardening, water-based polyacrylate coating on the outside diameter of the seal helps fill small imperfections in the housing bore.

FAG split spherical roller bearings – simple and quick to mount

Powertransmissions - FAG split spherical roller bearings – simple and quick to mountFAG split spherical roller bearings simplify and speed up bearing replacement, particularly in areas that are difficult to access such as shafts with multiple supports. In a split bearing, the inner ring, the outer ring, and the roller and cage assembly are divided into two halves that are clamped together with screws. Using the split version of these bearings allows numerous process steps to be omitted during mounting and dismounting. This means that downtimes can be significantly reduced and correspondingly high cost savings can be achieved. Because the dimensions have been exactly matched, the split spherical roller bearings can be installed in the same space as their unsplit counterparts (including the adapter sleeve). Applications include belt drives, paper machines, ships, conveying equipment, converters, rolling mills, and ventilation-related systems.

Splitting means improvement

In many applications, the spherical roller bearing is mounted on the shaft in such a complex fashion that it is also necessary to remove all the adjacent components in order for it to be replaced. This leads to long downtimes and complex additional tasks such as the removal of gears, clutches, and drive units. Extra costs are also incurred for additional replacement parts, tools, personnel, and even crane rental. When the split bearing version is used, most of these process steps are no longer required and the associated additional costs no longer arise. Mounting and dismounting can be carried out significantly faster and are simplified, especially in bearing positions that are difficult to access. Schaeffler offers split spherical roller bearings for shaft diameters ranging from 55 mm to 630 mm. In most cases, the outside diameter, the outer ring width, and the diameter of the shaft seat match the dimensions of the standard spherical roller bearings, including the adapter sleeve, so the bearings are interchangeable without any problems.

Application example: Installation of a split spherical roller bearing on the exhaust gas fan of a chemical plant

The spherical roller bearing in the exhaust gas fan of a chemical plant, which had an outside diameter of 230 mm, was in need of replacement. In the past, this application employed unsplit bearings that caused a downtime of 14 hours and generated costs of approximately 280,000 euros every time a bearing replacement was carried out. In addition to the immense outlay for the production stoppage, this included the costs for personnel, additional outlay for the alignment of the shaft, crane rental, and a further replacement bearing. With the FAG split spherical roller bearing, the downtime was only three hours and the overall costs 60,000 euros. The additional alignment, the crane rental, and the further replacement bearing were not required. The customer saved around 220,000 euros by using the split bearing.

The inner ring, outer ring, and roller and cage assembly of FAG split spherical roller bearings are divided into two halves.

The split version simplifies and speeds up bearing mounting, especially at installation points that are difficult to access.

Schaeffler’s Wheel Hub Drive Proves a Success in the Silvretta E-Car Rally

Schaeffler’s Fiesta E-Wheel Drive concept car successfully competed against other electric vehicles in the Silvretta E-Car Rally Race held for the fourth time in Montafon, Austria. The pre-production model featuring innovative electric wheel hub drives was developed on the basis of a Ford Fiesta in collaboration with Ford. The electric vehicle race over three alpine stages on three days required the drivers to make economical use of kilowatts, volts and amperes to avoid penalty points and finish with sufficient battery charge. The E-Wheel Drive wheel hub drive is an advance development project of the automotive supplier Schaeffler and Ford. During the alpine tour, however, it showed an impressive performance among the other electric vehicles, several of which are already in volume production.

“Schaeffler wanted to gain additional experience with regard to the level of development of our drive that is intended for the electric city vehicles of the future”, explains Prof. Peter Gutzmer, Chief Technology Officer at Schaeffler. “We completed the challenging three-day Silvretta E-Car Rally with the pre-production model without any problems even on long and steep hills and during downhill driving with energy recovery, which is a significant advantage offered by electric vehicles.”

The Fiesta E-Wheel Drive is powered by two highly-integrated wheel hub drives that are installed in the rear wheel arches. All components required for driving, deceleration and driving safety, such as electric motor, power electronics and controller, brake, and cooling system, are fitted in the wheel rims. They boast technical key data of 40 kW per drive, and a continuous output of 2 x 33 kW. When viewed as a traditional reading, this equates to 110 and 90 horsepower, respectively. The liquid-cooled wheel hub drive delivers up to 700 Nm of torque. The electrical voltage of the high-voltage drive is 360 - 420 V.

“The B-segment vehicle serves as a pre-production model. However, wheel hub drives have to be integrated into new vehicle concepts in order to demonstrate their strengths to the full,” explains Prof. Peter Gutzmer, who shared the cockpit with Prof. Pim van der Jagt, Managing Director of Ford Research & Advanced Engineering Europe. “Thanks to this highly-integrated wheel hub drive, we can now re-think the city car without restrictions,” says Prof. Peter Gutzmer. “This drive will be a key factor in new vehicle concepts and automobile platforms in the future. For electric vehicles used in urban environments, which may become obligatory in many densely populated areas, the wheel hub drive enables previously unknown space savings that cannot be achieved with internal combustion engines. In these new vehicle concepts, all components that are relevant for propulsion, braking, and driving safety are housed inside the wheel. The vehicle platform therefore provides maximum space for passengers, luggage, and for the battery, electronics, and communication systems.”

ContiTech Outstanding Interior Surfaces

Powertransmissions - ContiTech Outstanding Interior SurfacesWith materials made by Benecke-Kaliko, the new Opel Adam wins design prize for the best interior of a production car

A major award for an iconic city car and its interior surfaces made by Benecke-Kaliko: At the "Automotive Interiors Expo 2013" trade show in Stuttgart, the new Opel Adam won the design prize for the best interior in a factory-built vehicle. It is the first factory-built vehicle to feature Benecke-Kaliko's new scratch-resistant surface materials. The Opel designers benefited from Benecke-Kaliko's unique simulation technology. It allowed for realization of the best-possible dashboard design.

The international jury of renowned motoring journalists awarded the prize in recognition of the almost limitless personalization options for the interior styling of the Open Adam. The nearly 82,000 combinations feasible make it possible to fulfill almost every wish. Round instruments in the classic chronograph style, distinctly trendy lighting, chrome-finished controls, and the highly scratch-resistant TEPEO 2® Protect surface on the dashboard are all important design features.

Benecke-Kaliko took two years to develop this innovative material. The secret to its scratch-resistance lies in the use of polymers that elude sharp objects. On contact with hard edges, the elastic material simply yields before returning to its original form. Acella® cover material, also made by Benecke-Kaliko, reinforces the positive impression in the cockpit. It is used for the two-tone door inserts, while Beneron® compact foil is employed for the heelmat.

The numerous personalization options also pose a major challenge for the design teams. Instead of the usual handful of interior variants, thousands were developed for the Opel Adam. In addition to different color combinations, customers can also choose between different surface grains. Benecke-Kaliko was able to assist Opel here with its unique simulation technology.

3D-simulation helps save a lot of time and money in the development phase. It simulates the manufacture of components such as dashboards and door trims down to the smallest detail. Benecke-Kaliko was thus able to assist Opel with the dashboard in the design stage. It was in a position to provide rapid feedback on whether the requested design could be realized and where thin areas, creases or grain distortions might occur. As Michael Mäker, head of the Technology Center for Surfaces at Benecke-Kaliko explains: "End consumers would not be willing to accept relatively large and uneven distortions, particularly in the case of technical grains of the kind used on the Opel Adam." The Benecke-Kaliko simulation allowed the dashboard to be optimized for the best result. The latest version of the Surfvis™ 3D simulation program can represent the grain itself, enabling a photo-realistic display of the surfaces on the component.

Commenting on the award, Benecke-Kaliko Executive Board chairman Dr. Dirk Leiß noted: "This prize is another outstanding example of the surface expertise of the Benecke-Kaliko Group. In the end, our willingness to try out new things, our enthusiasm, and our creativity and initiative were rewarded."

The design award for the ambitious Opel Adam concept, with innovative interior materials made by Benecke-Kaliko, is not the first such prize conferred. Just launched in April of this year, the new model has already won five titles as part of the respected "Plus X Award" innovation competition as well as the important Red Dot Design Award.
