Hoʻokaʻawale ʻia ka lāʻau spline i ʻelua ʻano:
1) 'aʻa spline rectangular
2) involute spline shaft.
Hoʻohana nui ʻia ka lāʻau spline rectangular i ka lāʻau spline, aʻo ka involute spline shaft e hoʻohana ʻia no nā ukana nui a koi i ka pololei kikowaena kiʻekiʻe.a me nā pili nui.Hoʻohana maʻamau ʻia nā ʻāpana spline rectangular i nā mokulele, nā kaʻa, nā traktor, nā mea hana mīkini, nā mīkini mahiʻai a me nā mea hoʻoili mīkini maʻamau.Ma muli o ka nui-niho hana o ka rectangular spline shaft, he kiʻekiʻe haʻi hiki, maikaʻi neutrality a me ka alakaʻi maikaʻi, a me kona papau niho aʻa hiki ke hoʻohaʻahaʻa i kona kaumaha.Eia kekahi, ʻoi aku ka nāwaliwali o ka ikaika o ka lāʻau a me ka hub o ka spline shaft, ʻoi aku ka maʻalahi o ka hana ʻana, a hiki ke loaʻa ke kiʻekiʻe kiʻekiʻe ma ka wili.
Hoʻohana ʻia nā lāʻau spline involute no nā pilina me nā haʻahaʻa kiʻekiʻe, pololei ke kikowaena kiʻekiʻe, a me nā ana nui.ʻO kona mau hiʻohiʻona: ʻaʻohe ʻano o ka niho niho, a aia ka ikaika radial ma ka niho i ka wā i hoʻouka ʻia ai, hiki ke pāʻani i ke ʻano o ke kikowaena kikowaena, no laila ua like ka ikaika o kēlā me kēia niho, ikaika kiʻekiʻe a lōʻihi ke ola, ka ʻenehana hana. ua like ia me ka mea o ke kaa, a ua maʻalahi ka loaʻa kiʻekiʻe precision a me ka interchangeability
