Noma ngabe i-patent yokuqala ye-ai-roller screwyanikezwa ngo-1949, kungani ubuchwepheshe be-roller screw buyinketho engaziwa kakhulu kunezinye izindlela zokuguqulwa kwetorque ejikelezayo ibe ukunyakaza okuqondile?
Lapho abaklami becabangela izinketho zokunyakaza okulayini okulawulwayo, ingabe bahlola ngokugcwele izinzuzo ezinikezwa isikulufu se-roller ekusebenzeni, ngokuhlobene namasilinda amanzi noma umoya, kanye nebhola nomaizikulufo zokuhola? Izikulufu zamarola zinezinzuzo ezihlukile kunalezi ezinye izimbangi ezine kukho konke okucatshangelwayo okubalulekile kokukhetha. Yiqiniso, umklami ngamunye angase abe nemibandela yokukhetha ehlukene, ezonqunywa uhlelo lokusebenza.
Ngakho-ke, ekuhloleni ukukhathazeka okukhulu kokukhetha, nansi indlela isikulufu se-roller esenza ngayo…
Uma sithatha ukusebenza kahle njengombandela oyinhloko wokukhetha, isikulufu serola sisebenza kahle ngaphezu kwamaphesenti angama-90, futhi, kwezihlanu eziqashelwayo, kuphelaisikulufu sebholaangaqhathanisa. Isikhathi sokuphila side kakhulu ku-screw roller, ngokuvamile ubude obuphindwe izikhathi ezingu-15 kune-screw yebhola, futhi izinketho kuphela ze-hydraulic noma ze-pneumatic cylinder ezinikeza impilo yesevisi efanayo; nokho, bobabili badinga ukunakekelwa ukuze bagcine impilo ende.
Uma kuziwa ekunakekeleni ngokwaso, isikulufu serola sidinga ukulungiswa okuncane kakhulu njengoba ukungqubuzana okudalwe idizayini yesikulufu esigoqayo kukuncane, uma kuqhathaniswa nalokho okukhiqizwa ukungqubuzana kokuslayida. Nokho, isikulufu serola kusafanele sigcotshwe ukuze kuncishiswe ukuguga nokuqeda ukushisa. Ukunikeza ukuvikeleka okwanele kokungcola nakho kubalulekile empilweni ende yokusebenza, ngakho-ke ama-wiper angangezwa ngaphambili noma ngemuva kwentongomane ukuze kunwe izinhlayiya ezivela emicu kuyo yonke i-screw stroke. Izikhathi zokulungisa zizoncika ezintweni ezimbili eziyinhloko: izimo zokusebenza kanye nobubanzi besikulufa. Uma kuqhathaniswa, womabili amasilinda adonsa amanzi kanye nawomoya adinga ukunakwa okuphezulu kakhulu, futhi izikulufu zebhola zingahlupheka ngenxa yokubhoboza emgodini, kuyilapho amabhola angalahleka noma adinge ukushintshwa.
