Ukugaya kunye nokuRola-Iinzuzo kunye neeNgcaciso zeZikulufa zeBhola

Isikrufu sebhola yindlela yobuchule obuphezulu yokuguqula intshukumo ejikelezayo ibe sisindululo somgca. Iyakwazi ukwenza oku ngokusebenzisa indlela yebhola ejikelezayo phakathi kwe-screw shaft kunye ne nut. Kukho iintlobo ezininzi ezahlukeneyo zokujija ibhola, nganye inokusetyenziswa kwayo kunye neenzuzo.

Iindidi ezahlukeneyo zezikrufu zebhola

Kukho iintlobo ngeentlobo zezicelo kunye nokusetyenziswa kwezikrufu zebhola, ezineentlobo ezimbini eziphambili ezikhethwe ngabavelisi:

Ibhola eqengqelekayo isikrufu

Isikrufu sebhola esezantsi esichanekileyo

Umahluko phakathi kwesikrufu sebhola eqengqelekayo kunye nesikrufu esichanekileyo sebhola ephantsi

Umahluko wokuqala phakathi kwezikrufu zebhola eziqengqelekayo kunye nokuchanekaizikrufu zebhola zomhlabayinkqubo yokwenziwa kwabo. Izikrufu zebhola ephantsi zenziwe ngenkqubo yokukrazuka, apho i-abrasive cutter ihamba ngobude bendawo engenanto ebekwe ngokuthe tye, ikrola imisonto yesikrufu.

Izikrufu zebhola eziqengqelekayo zenziwa kusetyenziswa isixhobo esijikelezayo sife apho okungenanto kutyhalwa umva naphambili phakathi kweefa. Oku kunceda ukubumba imisonto kwi-screw, kwaye iyathandwa ngenxa yokusebenza kwayo okuphezulu.

Xa kuthelekiswa iindleko, kukho umahluko omkhulu phakathi kwezikrufu eziqengqelekayo zebhola kunye nezikrufu ezichanekileyo zomhlaba. Ngenxa yokusebenza kakuhle kwazo, izikrufu eziqengqelekayo zebhola zidla ngokuba neendleko ezingaphezulu kunezikrufu zomhlaba. Nangona kunjalo, izikrufu zomhlaba zihlala zikhethwa koomatshini abafuna ukuchaneka okuphezulu kuba banikezela ngokuchaneka ngakumbi kunezikrufu eziqengqelekayo.

Xa kuziwa ekuthelekiseni ukuchaneka, izikhonkwane zebhola zomhlaba ziphezulu kunezikhonkwane zebhola eziqengqelekayo kuba iintambo zenziwe ngokuchanekileyo kwaye zigudile kunomlingani wayo. Xa isikrufu sichaneke ngakumbi, i-nut ihamba kakuhle ecaleni kwe-shaft.

I-Pros and cons of ball screws

Kukho iinzuzo ezimbini eziphambili zokusebenzisa izikrufu zebhola: ukusebenza kakuhle kunye nokukhuhlana okuphantsi. Isikrufu sebhola sinikezela ngenqanaba eliphezulu lobuchule bomatshini. Ubalo lubonisa ukuba banokunikezela ukuya kutsho kuma-90% ngokufanelekileyo xa kuthelekiswa nezikrufu zelothe, ezibonelela ngobuchule obuphakathi kwe-20% kunye ne-25%.

Izikrufu zebhola zikwavelisa ukukhuhlana okuncinci, okulungele ukuvelisa usetyenziso olugudileyo. Ziyilwe nge nut apho iibheringi zebhola zijikeleza kwaye zenze umphezulu ogudileyo wokutyibilika kwisikrufu. Oku kunciphisa ukukhuhlana kwaye kwandisa ixesha lokuphila lebhola.

Kukho ezinye izibonelelo zokusebenzisa izikrufu zebhola, ezi:

1）Amabakala aphezulu okuchaneka kokuchaneka okukhulu kwendawo

2）Ifumaneka kwiintlobo eziqengqelekayo kunye nomhlaba

3）Inokulungiswa ukuze kwandiswe/kucuthwe ukulayisha kwangaphambili

4）Kufuneka kutshintshwe kancinane

5）Ifumaneka kwi-screw diameters ukusuka kwi-4mm ukuya kwi-80mm

Ngokubhekiselele kwii-negatives ze-screws zebhola, zimbini kuphela ngokwenene: ukuchaphazeleka kwabo ukuba baqhutywe ngasemva kunye neendleko zabo.

Kuba izikrufu zebhola zidala ukukhuhlana okuphantsi, zinokuqhutywa ngasemva kwii-engile ezithile zokukhokela.

Izikrufu zebhola zinokubiza kancinci kunezinye iinketho. Bathanda ukuba neendleko ezingaphezulu kancinci kunezixhobo zoomatshini ezifanayo, kubandakanywa izikrufu zelothe. Ke kwiinkampani ezivelisa uhlahlo lwabiwo-mali olungqongqo, iindleko eziphezulu zinokuba sisithintelo.

Nangona kunjalo, ngenxa yeenzuzo zabo ezicacileyo zobuchule obuphezulu bomatshini kunye nokukhuhlana okuphantsi kwangaphakathi, izikrufu zebhola ziselukhetho oluthandwa kakhulu kubakhiqizi abaninzi kwaye lutyalo-mali olulumkileyo.
