The option lets users fix a specific linear travel speed in one or both directions of travel using set screws which are inserted into the drive housing. No adjustments to motor speed or controls are necessary.</p></div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/mechanical-drives/mechanically-controlled-linear-drives" target="_blank">read more</a></p> http://machinedesign.com/mechanical-drives/mechanically-controlled-linear-drives#comments Mechanical Drives Thu, 07 Nov 2013 15:18:00 +0000 31891 at http://machinedesign.com Disc-pack coupling uses friction to transmit torque http://machinedesign.com/mechanical-drives/disc-pack-coupling-uses-friction-transmit-torque <div class="node-body article-body"><p> The LP Survivor Series of disc-pack couplings from R+W America, Bensenville, Ill. (<a href="http://www.rw-america.com" title="www.rw-america.com">www.rw-america.com</a>), transmit torque using friction. A series of bushings press the disc pack together. Precise locating features on the hubs and spacers create a concentric fit. Bolt assemblies get tightened through the hubs, spacers, and bushing to generate the needed clamping pressure across the face of the disc packs to transmit power.</p></div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/mechanical-drives/disc-pack-coupling-uses-friction-transmit-torque" target="_blank">read more</a></p> http://machinedesign.com/mechanical-drives/disc-pack-coupling-uses-friction-transmit-torque#comments Mechanical Drives Tue, 29 Oct 2013 16:28:00 +0000 31641 at http://machinedesign.com
