Iintambo zebholaZiyindibaniselwano yamacandelo amabini - isikrufu sebhola kunye ne-spline yebhola ejikelezayo. Ngokudibanisa i-drive element (i-ball screw) kunye nesikhokelo (i-rotaryibhola spline), i-ball screw splines inokubonelela ngeentshukumo zomgca kunye ne-rotary kunye neentshukumo ze-helical kuyilo oluqinileyo, oluhlangeneyo.
---BzonkeSabasebenzi
Izikrufu zebholasebenzisa iibhola zentsimbi ezijikelezayo kwi-nut eyenziwe ngokuchanekileyo ukuqhuba imithwalo kwiindawo ezichanekileyo. Kuyilo oluninzi, i-screw ikhuselekile kwelinye okanye zombini iziphelo kwaye i-nut ithintelwe ekujikelezeni ngendlu enezitshixo okanye esinye isixhobo esichasene nokujikeleza. Ngenxa yokuba isikrufu sithintelwe ekubeni sihambe ngokulandelelana, intshukumo ikhutshelwa kwinut yebhola, ehamba ngobude be-screw shaft.
Olunye uyilo lwe-screw yebhola lubandakanya iibheringi zoqhagamshelwano ze-radial angular kwidayamitha yangaphandle ye-nut, evumela i-nut ukuba iqhutywe-ngokuqhelekileyo ngebhanti kunye ne-pulley assembly eqhagamshelweimoto-ngelixa isikrufu sihlala simile ngokupheleleyo. Xa i-motor ijika, ijikeleza i-nut kubude be-isikrufu sokukhokela. Olu cwangciso luhlala lubizwa ngokuba yi "driven nut" uyilo.
---Ibhola Spline
Imigca yebhola yinkqubo yesikhokelo engqameneyo efana neshafti engqukuva kunye neebheringi zebhola ezijikelezayo, kodwa ezinemijelo echanekileyo eyenziwe ngoomatshini ecaleni kobude beshafti. Ezi grooves zithintela i-bearing (eyaziwa ngokuba yi-spline nut) ekujikelezeni ngelixa ivumela i-ball spline ukuba idlulise i-torque.
Ukwahluka komgangatho webhola spline yibhola ejikelezayo spline, eyongeza into ejikelezayo - igiya, i-roller enqamlezileyo okanye ibhola yokudibanisa i-angular - kwidamitha engaphandle ye-spline nut. Oku kuvumela i-Rotary ball spline ukubonelela zombini intshukumo yomgama kunye ne-rotary.
---Indlela I-Ball Screw Splines esebenza ngayo
Xa i-screw yebhola ye-nut eqhutywayo idityaniswe ne-spline yebhola ejikelezayo, isiphumo soqwalaselo siqhele ukubizwa ngokuba yi-screw spline yebhola. Ishafti ye-screw spline yebhola ineentambo kunye ne-spline grooves ngobude bayo, kunye nemisonto kunye ne-grooves "enqumlayo" enye kwenye.
I-ball screw spline ine-ball nut kunye ne-spline nut, nganye ine-radial bearing kumda wangaphandle we-nut.
Iintlobo ezintathu zentshukumo: umgca, i-helical kunye ne-rotary.
Iiassemblies zebhola Screw spline zinciphisa intshukumo yomgama webhola jijwa nuts kunye nebhola spline nuts. Ngokuqhuba i-nut yebhola kunye ne-spline nut kunye okanye ngabanye, iintlobo ezintathu ezahlukeneyo zentshukumo zinokuveliswa: i-linear, i-helical kunye ne-rotary.
Kubaintshukumo yomgca, i-ball nut iqhutywa ngelixa i-spline nut ihlala imile. Ekubeni i-nut yebhola ayikwazi ukuhamba ngokulandelelana, i-shaft idlula kwi-nut yebhola. I-spline nut emileyo ikhusela i-shaft ekujikelezeni kweli nqanaba, ngoko ke ukuhamba kwe-shaft kumgca ngokuchanekileyo ngaphandle kokujikeleza.
Kungenjalo, xa i-spline nut ivuliwe kwaye ibhola nut ihlala imile, i-ball spline ibangela intshukumo ejikelezayo kwaye imisonto apho ibhola ikhuselwe khona ibangela ukuba i-shaft ihambe ngokomgca njengoko ijikeleza, okukhokelela kwintshukumo ye-helical.
Xa omabini amandongomane ecushiwe, ukujikelezwa kwe nut yebhola ngokuyimfuneko kuyayicima intshukumo yomgca eyenziwe yibhola spline, ngoko ke ishafuti iyajikeleza ngaphandle kokuhamba ngemigca.
