Additionally, teeth can be machined with asymmetric distributions to limit the number of positions where they fit. This is an ideal solution when the shafts need to be engaged and disengaged repeatedly, but the synchronism must be maintained at all times.<\/p><h3>Key features<\/h3><div id=\"attachment_8075\" style=\"width: 366px\" class=\"wp-caption alignright\"><img decoding=\"async\" aria-describedby=\"caption-attachment-8075\" class=\"wp-image-8075\" src=\"https:\/\/www.eide.net\/wp-content\/uploads\/2017\/09\/teet-detail-couplint-joint-800x800.png\" alt=\"Hirth joint\" width=\"356\" height=\"200\" \/><p id=\"caption-attachment-8075\" class=\"wp-caption-text\">120\u00ba Teeth Hirth coupling detail.<\/p><\/div><ul><li>Very high loads can be transferred using a small and simple clutch, that being composed of just 3 pieces (2 discs and a screw) is more economical than other coupling solutions.<\/li><li>There is no backlash.<\/li><li>The coupling is self-centring; thanks to which it\u2019s commonly used in very high RPM gas turbines.<\/li><li>If there is some friction and the screws loosen, screwing them down again would restore the firmness.<\/li><li>A more complex system can be developed using pneumatic cylinders.<\/li><\/ul><h3>Main applications<\/h3><p>This system is widely used in the manufacturing industry. <strong>Hirth Couplings were first used in aircraft engine crankshafts<\/strong>. Many cylinders had to be connected, often together with a reducer or a transmission booster. This made it complicated to manufacture a one-piece crankshaft, so Hirth Couplings were used to join the different sections.<\/p><p>They are also used in gas turbine shafts, in accessories for surgical operating tables, in agricultural machines and bicycle parts and frames, such as the bicycle crankset.<\/p><p>Large diameter Hirth Couplings can perform extremely <strong>accurate and repeatable rotational positioning.<\/strong> For this reason, they are used in indexing heads and rotary tables for precision machining and inspection tasks.<\/p><p>Finally, but no less important, in <a href=\"\/en\/producto\/ecd-electromagnetic-tooth-clutch\/\">electromagnetic clutches<\/a> and <a href=\"https:\/\/eide.net\/producto\/embrague-neumatico-dentado-ne-cd\/\">pneumatic clutches<\/a>.<\/p><h3>Custom design<\/h3><p>At EIDE, we can offer custom designs.
