En basit yap\u0131 olarak bir serbestlik dereceli kam mekanizmalar\u0131 \u00fc\u00e7 uzuvlu bir kinematik zincirden olu\u015fur. Mekanizma serbestlik derecesi bir olmas\u0131 i\u00e7in zincirde kam \u00e7iftinin d\u0131\u015f\u0131nda bulunan di\u011fer kinematik \u00e7iftlerin serbestlik derecesi bir olmas\u0131 gerekir. Bu durumda, di\u011fer kinematik \u00e7iftler kayar veya d\u00f6ner mafsal olabilirler. Yukar\u0131da g\u00f6sterildi\u011fi gibi, 3 de\u011fi\u015fik zincir ve bu zincirlerden elde edilebilen yedi de\u011fi\u015fik mekanizma m\u00fcmk\u00fcnd\u00fcr. Genel olarak kam \u00e7iftini olu\u015fturan her iki y\u00fczeyde farkl\u0131 bir e\u011fri olabilir isede, imalat kolayl\u0131\u011f\u0131ndan dolay\u0131 y\u00fczeylerden biri bir do\u011fru veya dairedir. Daire olarak kendi ekseni etraf\u0131nda d\u00f6nebilen bir toparlak yerle\u015ftirilerek kayma s\u00fcrt\u00fcnmesi d\u00f6nme s\u00fcrt\u00fcnmesine d\u00f6n\u00fc\u015ft\u00fcr\u00fcl\u00fcr.<\/p>\n

Bu nedenle uygulamada kam mekanizmalar\u0131n\u0131n s\u0131n\u0131fland\u0131r\u0131lmas\u0131nda \u00fc\u00e7 de\u011fi\u015fik kriter kullan\u0131l\u0131r.<\/p>\n

Kuvvet kapal\u0131 kam \u00e7iftleri daha yayg\u0131n olup kam \u00e7ifti y\u00fczeyine etkiyen normal kuvvetin ne \u015fekilde olu\u015ftu\u011funa g\u00f6re s\u0131n\u0131fland\u0131r\u0131labilir (yay, a\u011f\u0131rl\u0131k, pn\u00f6matik, santrif\u00fcj, vb).<\/p>\n

\u015eekil kapal\u0131 kamlarda uzuvlar iki noktadan temas ederler ve kinematik \u00e7iftlerin temas\u0131 i\u00e7in ek bir kuvvete ihtiya\u00e7 yoktur.<\/p>\n
