The conical elu-eji dị ka indexing elu, nke dị ka na-anọchi anya dobe wheel nke ọgwụgwụ truncated elu anya site akpịrị na hyperbola.

Atụmatụ nkengwa ngwa hypoid:

1. Mgbe ị na-eche ezé nke nnukwu wiil, tinye obere wiil n'akụkụ aka nri nke nnukwu wheel ahụ. Ọ bụrụ na axis nke obere ogwe dị n'okpuru axis nke nnukwu wheel, a na-akpọ ya nkwụsị ala, ma ọ bụghị ya bụ nkwụsị elu.

2. Ka nkwụsị nkwụsị na-abawanye, oghere helix nke obere wiil na-abawanye, na dayameta dị n'èzí nke obere wiil ahụ na-abawanye. N'ụzọ dị otú a, ike na ike nke obere wiil nwere ike ime ka ọ dịkwuo mma, na ọnụ ọgụgụ nke ezé nke obere wiil nwere ike belata, na enwere ike ịnweta nnyefe oke mbelata.
