Silsiladdu guud ahaan waa isku xidh bir ah ama faraanti, kaas oo inta badan loo isticmaalo gudbinta farsamada iyo jiidista. Walxaha qaab silsilad ah loo isticmaalo in lagu xannibo marinnada taraafikada (sida albaabka waddooyinka, webiyada ama dekedaha), silsiladaha loo isticmaalo gudbinta farsamada.

1. Silsiladda waxaa ku jira afar taxane: silsilad gudbin; silsilad gudbin; silsilad jiidid; silsilad gaar ah.

2. Taxane isku xir ama wareegyo oo badanaa laga sameeyo bir: walxo qaab silsilad ah oo loo isticmaalo in lagu xannibo marinnada taraafikada (sida albaabka laga galo waddo, webi ama deked); silsilad loo isticmaalo gudbinta farsamada.

3. Silsiladaha waxaa loo qaybin karaa silsilado duuban oo sax ah oo gaaban; silsilado duuban oo sax ah oo gaaban; silsilado duuban oo saxan oo qaloocan oo loogu talagalay gudbinta shaqada culus; silsilado loogu talagalay mashiinnada sibidhka iyo silsiladaha saxanka; silsilado xoog badan.

Qaab-dhismeedka silsiladda gudbinta waxay ka kooban tahay isku xidhka silsiladda gudaha iyo isku xidhka silsiladda dibadda. Waxay ka kooban tahay shan qaybood oo yaryar: saxanka silsiladda gudaha, saxanka silsiladda dibadda, biin, gacan iyo duub. Tayada silsiladdu waxay ku xidhan tahay biinanka iyo gacanta.

Qalabka gudbinta ee mashiinnada, qaybaha gudbinta ee caadiga ah ee la isticmaalo waxaa ka mid ah pulleys, gears, gears dixiri, racks iyo pinions, iyo boolal laws. Qaybahan gudbinta, isha korontada iyo hawl-wadeenka, ama xidhiidhka ka dhexeeya labada hawl-wadeen, waxaa loo yaqaan isku xirka gudbinta. Taxane walxo gudbin oo isku xigxiga oo sameeya isku xirka gudbinta waxaa loo yaqaan silsilad gudbin.

Silsiladda gudbinta badanaa waxay ka kooban tahay laba nooc oo farsamooyinka gudbinta ah: hal nooc waa farsamo gudbinta oo leh saamiga gudbinta go'an iyo jihada gudbinta, sida lammaanaha gear-ka saamiga go'an, lammaanaha turbine-ka dirxiga, iwm., oo loo yaqaan habka gudbinta saamiga go'an; nooca kale wuxuu ku salaysan yahay shuruudaha habaynta. Habka gudbinta ee beddeli kara saamiga gudbinta iyo jihada gudbinta, sida habka gudbinta gear-ka isbeddelka, habka gudbinta gear-ka simbiriirixan, iwm., waxaa loo yaqaan habka beddelka.
