Li-spiral bevel gears li arotsoe ka mefuta e 'meli, e' ngoe e le spirallisebelisoa tsa bevel, eo selepe sa eona se seholo le se senyenyane se kopanang; e 'ngoe ke hypoid spiral bevel gear, e nang le sebaka se itseng sa offset pakeng tsa axle e khōlō le e nyenyane. Li-gear tsa Spiral bevel li sebelisoa haholo libakeng tsa phetisetso ea mochini joalo ka likoloi, lifofane le meepo ka lebaka la melemo ea tsona e kang coefficient e kholo ea ho fetana, matla a ho jara, karolelano e kholo ea phetisetso, phetisetso e boreleli le lerata le tlase. Litšobotsi tsa eona ke:

1. Lisebelisoa tse otlolohileng tsa bevel: Mohala oa leino ke mola o otlolohileng, o phunyeletsang tlhōrōng ea khoune, o honyela leino.

2. Helical bevel gear: Mohala oa leino ke mola o otlolohileng 'me o lebile ho ntlha, o honyela leino.

3. Li-spiral bevel gears: li-gear tse khonang ho khutlisetsoa morao (hape li loketse likere tsa bolelele bo lekanang).

4. Cycloid spiral bevel gear: meno a contour.

5. Zero degree spiral bevel gear: Meno a fokotsang habeli, βm=0, a sebelisetsoang ho fetola likere tse otlolohileng tsa bevel, ka botsitso bo betere, empa eseng hantle joalo ka likere tsa spiral bevel.

6. Cycloid tooth zero-degree bevel gear: Meno a contour, βm=0, a sebelisoang ho nkela likere tse otlolohileng tsa bevel sebaka, ka botsitso bo betere, empa eseng hantle joalo ka likere tsa spiral bevel.

7. Mefuta ea bophahamo ba leino la likere tsa spiral bevel li arotsoe haholo ka meno a fokotsehileng le meno a bolelele bo lekanang. Meno a fokotsehileng a kenyelletsa meno a sa lekanang a ho hlakisoa ha hlooho, meno a fokotsehileng a mabeli le meno a fokotsehileng habeli.

8. Meno a contour: meno a pheletso e kholo le pheletso e nyane a bolelele bo lekanang, hangata a sebelisoa bakeng sa likere tsa bevel tse oscillating.

9. Meno a fokolang a sebaka se seng sa isotopic: litlhōrō tsa sub-cone, top cone le root cone li iketsahalla ka tšohanyetso.
