Various options can be attached to a geared motor to meet application specifications. The system consists of a precision spindle drive attached to an electronic control system, and an absolute sensor for position.</p></div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/mechanical-drives/linear-drive" target="_blank">read more</a></p> http://machinedesign.com/mechanical-drives/linear-drive#comments Mechanical Drives Mon, 23 Jun 2014 18:46:00 +0000 38631 at http://machinedesign.com Roller-Pinion System http://machinedesign.com/mechanical-drives/roller-pinion-system <div class="node-body article-body"><p><img alt="" src="/site-files/machinedesign.com/files/uploads/2014/06/Nexen-RPS-Rack.gif" style="width: 350px; height: 280px; margin: 5px; float: right;" />The RPS rack is a roller-pinion system designed to eliminate the shortcomings of linear-drive systems. It replaces spur-gear teeth with bearing-supported rollers that engage a rack-tooth profile. The rollers eliminate sliding friction with smooth rolling friction for a 99%-efficient rotary to linear-motion conversion.</p></div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/mechanical-drives/roller-pinion-system" target="_blank">read more</a></p> http://machinedesign.com/mechanical-drives/roller-pinion-system#comments Mechanical Drives Mon, 23 Jun 2014 18:36:00 +0000 38621 at http://machinedesign.com Spotlight: Mechanical Slides, Drives, Gears http://machinedesign.com/mechanical-drives/spotlight-mechanical-slides-drives-gears <div class="node-body gallery-body"><p>The latest mechanical slides, drives, and gears products.</p> </div> <div class="og_rss_groups"></div> http://machinedesign.com/mechanical-drives/spotlight-mechanical-slides-drives-gears#comments Mechanical Drives Mon, 23 Jun 2014 16:36:00 +0000 38541 at http://machinedesign.com Motors Not Turbines Drive Heavy Equipment http://machinedesign.com/mechanical-drives/motors-not-turbines-drive-heavy-equipment <div class="field-byline"> Sumit Singhal, Consulting Engineer, Siemens Industry Inc., Norwood, Ohio </div> <div class="field-deck"> Electric motors with magnetic bearings can drive high-speed shafts in heavy equipment. </div> <div class="node-body article-body">High-speed rotating machinery presents tough challenges for engineers, particularly in heavy equipment that draws many megawatts of power.
