Ulaha spline waxay door muhiim ah ka ciyaaraan mishiinada beeraha, taas oo u sahlaysa in si sahlan oo hufan loogu kala wareejiyo awooda qaybaha kala duwan. Ulahani waxay leeyihiin godadka taxana ah ama kabyo kabyo is-dhexyaac leh oo u dhigma jeexjeexyo u dhigma oo ku yaal qaybaha isku-tagga, hubinta gudbinta qulqulka oo sugan iyada oo aan simbiriirixin. Naqshadeyntani waxay u oggolaaneysaa labadaba dhaqdhaqaaqa wareega iyo qulqulka axial, samaynta xargaha spline ee ku habboon baahida culus ee qalabka beeraha.

Mid ka mid ah codsiyada aasaasiga ah ee ulaha spline ee beeraha ayaa ku jira nidaamyada Awood-qaadista (PTO). Ulaha PTO waxaa loo isticmaalaa in lagu gudbiyo awoodda cagaf-cagafyada qalabyo kala duwan sida mashiinnada, baallayaasha, iyo tillers. Xidhiidhka kabidda ayaa u oggolaanaya toosin sax ah, wareejin awood adag, iyo awoodda u adkeysiga culeysyada sare iyo walbahaarka, hubinta adkeysiga xaaladaha adag ee shaqada.

Intaa waxaa dheer, shafka spline waxaa loo isticmaalaa hababka gudbinta iyo bambooyin hydraulic, halkaas oo gudbinta awoodda lagu kalsoonaan karo iyo dhaqdhaqaaqa axial waa lagama maarmaan. Ulahaan waxaa sida caadiga ah laga sameeyaa walxo aad u sarreeya sida birta daawaha ama birta aan lahayn, taasoo bixisa iska caabin aad u fiican iyo cimri dheer.

Isticmaalka mashiinnada spline ee qalabka beeraha waxay kor u qaadaan waxtarka, waxay yareeyaan shuruudaha dayactirka, waxayna hubisaa in beeralaydu ay ku tiirsan yihiin mishiinkooda hawlaha muhiimka ah inta lagu jiro beerista, goosashada, iyo diyaarinta beerta.
