Ma spline shaft amatenga gawo lofunikira pamakina aulimi, ndikupangitsa kusamutsa bwino komanso koyenera kwa mphamvu pakati pa zigawo zosiyanasiyana. Mitsinje iyi imakhala ndi mizere ingapo kapena ma splines omwe amalumikizana ndi ma grooves ofananira m'magawo okwerera, kuwonetsetsa kuti ma torque akuyenda motetezeka popanda kutsetsereka. Mapangidwe awa amalola kusuntha kozungulira komanso kutsetsereka kwa axial, kupangitsa kuti ma spline shaft akhale abwino pazofunikira zolemetsa za zida zaulimi.

Chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi ma spline shafts paulimi ndi machitidwe a Power Take-Off (PTO). PTO shafts amagwiritsidwa ntchito kutumiza mphamvu kuchokera ku thirakitala kupita ku zida zosiyanasiyana monga zotchera, mabala, ndi ma tiller. Kulumikizana kwa spline kumathandizira kulondola kolondola, kusuntha kwamphamvu kwamphamvu, ndikutha kupirira katundu wambiri ndi kupsinjika, kuwonetsetsa kukhazikika pamikhalidwe yovuta.

Kuonjezera apo, ma spline shafts amagwiritsidwa ntchito mu machitidwe opatsirana ndi mapampu a hydraulic, kumene kutumizira mphamvu zodalirika ndi kuyenda kwa axial ndizofunikira. Mitsukoyi nthawi zambiri imapangidwa kuchokera kuzinthu zamphamvu kwambiri monga chitsulo cha alloy kapena chitsulo chosapanga dzimbiri, zomwe zimapereka kukana kovala bwino komanso moyo wautali.

Kugwiritsa ntchito ma spline shaft pazida zaulimi kumakulitsa luso, kumachepetsa zofunikira zosamalira, ndikuwonetsetsa kuti alimi amadalira makina awo pa ntchito zofunika kwambiri panthawi yobzala, kukolola, ndi kukonzekera m'munda.
