Amagiya wezikelemuizici:
1. Ihlinzeka ngama-raios amakhulu okuncishiswa kwebanga elinikeziwe lesikhungo
2. Isenzo esihle futhi esibushelelezi se-meshing
3. Akwenzeki ukuthi isondo lezikelemu lishayele i-wor ngaphandle uma kunemibandela ethile
Isimiso sokusebenza kwegiya lezikelemu:
Amashafu amabili egiya lezikelemu kanye ne-worm drive ancikene komunye nomunye; isibungu singathathwa njenge-helix enezinyo elilodwa (ikhanda elilodwa) noma amazinyo amaningana (amakhanda amaningi) alimele eduze kwe-helix ku-cylinder, futhi igiya lezibungu lifana negiya elitshekile, kodwa amazinyo alo afaka isibungu. Phakathi ne-meshing, ukuzungezisa okukodwa kwesibungu kuzoshayela isondo lesikelemu ukuze lijikeleze ngezinyo elilodwa (isibungu esine-single-end worm) noma amazinyo amaningana (multi-end worm).rod), ngakho-ke isilinganiso sejubane i yokudluliselwa kwegiya lezikelemu = inombolo amakhanda esikelemu Z1/inani lamazinyo esondo lesikelemu Z2.
