Del-Tron's newest actuators run at speeds up to 5.1 m/sec, and without lubrication or maintenance under normal conditions. They have travel lengths up to 6m with a repeatability of ±0.025 mm and a linear accuracy of ±0.083 mm/m. They come with a steel-reinforced polyurethane belt, and the drive features Del-Tron's own extrusion design. The planetary gearheads can handle input speeds up to 10,000 rpm and have high output loads. They use zero helix angle gears, not helical gears and large, sealed, deep-groove ball bearings support the output shaft. The actuators come with a choice of steel concave rollers on chrome-plated steel rails, a plastic-coated needle bearing assembly, or plastic bearings on aluminum rails. The steel bearings come with lifetime lubrication, while the plastic bearings need no lubrication at all.
Almost every automaker has had to 'pick a side' when it comes to alternative fuel options and ways to divest from a reliance on gasoline. Fiat is looking to back compressed natural gas or liquid propane as an interim solution.
Designing and filling a new type of water bottle might take less engineering work, but the description will help kids understand how science, math, and engineering influence their lives even through things that seem mundane.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
