High positional accuracy in a zero-backlash gearhead
Built for OEM robotic applications, the SHD Gearhead Size 14 has a 1.5 arc-min positional accuracy and ±5 arc-sec repeatability. It has a high precision harmonic drive gearing and high-capacity cross roller bearing, with a rated torque of 33 inches-lb and a maximum torque of 310 inches-lb. It has an outer diameter of 70 mm, is only 17 mm long, and comes in 50:1 and 100:1 gear ratios. It has necessary motion control components like the harmonic drive gear and the cross roller bearing, which allows it to be incorporated into the machine housing.
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.
