Electrification has really brought ball bearings back into focus as the primary bearing in our drive systems. Some boxes have tapers on the slower shafts for stiffness and others are using a ball/cylindrical combo for efficiency. Regardless, we all face the same challenge on the primary shaft in dealing with the potential of 18,000–20,000+ rpm speeds coming out of the motor. Plenty of applications run 20,000 rpm; what makes the automotive motor unique is, in addition to speed, we are driving huge torques, frequent torque reversals and a huge range of temperatures both internally and geographically. Of course, this all needs to be suited for high-volume manufacturing as well. Adding full ceramic balls, a PEEK cage and a high precision classification is a really easy way to run greater than 20,000 rpm all day but is an expensive option. One bearing alone could hurt the cost competitiveness of your gearbox. In the case where a single bearing can change the landscape of your project, it is worth taking a little time to understand exactly what the drivers of our speed limitations are.
The engineering community is fascinated with big, shiny, yellow machines. Walk into any manufacturing facility around the globe and you’ll find guests huddled around the biggest, loudest, and most intimidating equipment on the shop floor. These large machines must play by the same rules as everybody else—they need to reduce energy consumption, lower plant costs, and increase productivity. Many power transmission component suppliers are tasked with optimizing this equipment.
Recently, the Swedish rolling bearing manufacturer SKF and the Swiss gearbox design software developer KISSsoft have incorporated SKF’s bearing calculation service within KISSsoft's software. With the so-called SKF Bearing Module in KISSsoft, engineers will have direct access to SKF’s bearing technology and bearing performance data.
A new version of the MESYS shaft and rolling bearing analysis software including new functionality is available. The bearing analysis software allows the calculation of the load distribution within the bearing and bearing life according to ISO/TS 16281 and it is integrated in a shaft system calculation with additional possibilities like modal analysis, strength calculation for shafts and interfaces to gear calculations. Currently the software is used by customers in 30 countries on four continents.
2022 marks the 20th Anniversary of SMT’s focus on providing the tools and knowledge to drive engineering innovation in gearbox system analysis. With this historic company anniversary, the company has announced the return of the North America User Forum.
Torque Transducers and Test Machinery experience extreme demands including high torque loads and high operating speeds which cause stress on connected components. To assure these systems generate accurate test data when experiencing these conditions, system designers specify CD Couplings from Zero-Max.
Siemens Digital has added features and updates for Simcenter SPEED, Simcenter Motorsolve and Simcenter MAGNET 2022.1 to improve accuracy, flexibility and connectivity. This 2022.1 update makes Simcenter SPEED and Simcenter Motorsolve more accurate and better integrated to Simcenter STAR-CCM+.
SEGULA Technologies and British scale up Senseye, specialized in predictive maintenance based on artificial intelligence, have announced the signing of a partnership.
The S-series hydraulic motors from Black Bruin are designed for demanding recycling applications with direction changes and shock loads, which can be hard on shredders and their rotors. The power of the S-series helps handle varied and inconsistent waste material effortlessly and clears jams with ease
