Zochita za Worm gear:
1. Amapereka raios zazikulu zochepetsera pamtunda womwe wapatsidwa
2. Zochita bwino komanso zosalala za meshing
3. Sizingatheke kuti gudumu la nyongolotsi liyendetse wola pokhapokha ngati zinthu zina zakwaniritsidwa
Mfundo yogwiritsira ntchito zida za Worm:
Mitsinje iwiri ya zida nyongolotsi ndi nyongolotsi galimoto ndi perpendicular wina ndi mzake; nyongolotsi imatha kuonedwa ngati helix yokhala ndi dzino limodzi (mutu umodzi) kapena mano angapo (mitu ingapo) yovulala pa helix pa silinda, ndipo zida za nyongolotsi zimakhala ngati oblique.zida, koma mano ake atsekereza mphutsi. Pa meshing, kusinthasintha kumodzi kwa nyongolotsi kumayendetsa gudumu la nyongolotsi kuti lizizungulira dzino limodzi (nyongolotsi imodzi) kapena mano angapo (worm-end worm) ndodo), kotero chiŵerengero cha liwiro i cha kufala kwa gear nyongolotsi = chiwerengero ya mitu ya nyongolotsi Z1/chiwerengero cha mano a gudumu la nyongolotsi Z2.
