Ha u khetha mofuta o nepahetseng oalisebelisoa tsa helicalbakeng sa litsamaiso tsa ho tsamaisa merafo, nahana ka lintlha tse latelang tsa bohlokoa:

1. **Litlhoko tsa Mojaro**: Khetha mofuta oa gear o nepahetseng ho latela mojaro o sebetsang oa sepalangoang.

Li-gear tsa Helical li loketse lits'ebetso tse tsamaisang meepo tse boima haholo hobane li khona ho mamella meroalo ea bohlokoa ea axial le radial.

2. **Tlhahiso ea Phetiso**: Khethalisebelisoa tsa helical mefuta e nang le ts'ebetso e phahameng ea phetisetso ho netefatsa tahlehelo e nyane ea matla nakong ea phetisetso ea matla. Li-gear tsa Helical hangata li sebetsa hantle ho feta likere tse otlolohileng.

3. **Sebaka sa ho Kenya**: Nahana ka sebaka sa ho kenya thepa 'me u khethe lebokose la li-gearbox le entsoeng ka bonngoe bakeng sa ho kenya le ho hlokomeloa habonolo ka har'a libaka tse fokolang.

4. **Ho Ikamahanya le Boemo ba Tikoloho**: Hangata tikoloho ea merafo e thata, kahoo hoa hlokahala ho khetha likere tse entsoeng ka thepa e sa jeng le e sa senyeheng ho netefatsa ts'ebetso e tsitsitseng maemong a mocheso o phahameng, lerōle le mongobo.

5. **Taolo ea Lerata le Vibration **: Khethalisebelisoa tsa helicalmefuta e ka atlehang ho fokotsa lerata le ho thothomela ho ntlafatsa boiketlo ba tikoloho ea ho sebetsa le ho tšepahala ha thepa.

6. **Tlhokomelo le Tshebeletso**: Nahana ka litlhoko tsa tlhokomelo ea likere ebe u khetha mefuta ea lisebelisoa tsa helical tseo ho leng bonolo ho li hlokomela le ho fana ka litšebeletso ho fokotsa litšenyehelo tsa ts'ebetso le ho lelefatsa bophelo ba tšebeletso ea thepa.

7. **Mokhoa oa ho Khanna**: Khetha mofuta o nepahetseng oa lisebelisoa tsa helical ho latela mokhoa oa ho khanna oa conveyor (joalo ka motlakase oa motlakase kapa hydraulic drive) ho netefatsa hore o lumellana le tsamaiso ea koloi.

8. **Maemo a Moralo le Litlhaloso**: Latela litekanyetso tse amehang tsa moralo le lintlha tsa polokeho, joalo ka "Khoutu ea Tšireletseho bakeng sa Mabanta a Conveyors Meepong ea Mashala" (MT654—2021), ho netefatsa hore likere tse khethiloeng li finyella litlhoko tsa indasteri.

Ka ho nahana ka lintlha tsena ka botlalo, o ka khetha mofuta o loketseng ka ho fetisisa oa lisebelisoa tsa helical bakeng sa litsamaiso tsa li-conveyor tsa merafo, ka hona, ho ntlafatsa ts'ebetso le ts'epahalo ea sistimi.
