Iyunithi yokunyakaza iyingxenye ebaluleke kakhulu esakhiweni serutha ye-CNC, futhi idlala indima ebalulekile ekunembeni nasekusebenzeni komshini. Indlela evamile yokunyakaza ngokuyinhloko inesakhiwo sokubeka kanye nephini kanye nesakhiwo se-ballscrew, ngakho-ke sichaza ikakhulukazi izici nezinzuzo zalezi zinhlobo zesakhiwo sokunyakaza.
1. Ukudluliswa kwe-rack kanye ne-pinion kubukeka kumbono wokudlulisela mayelana nomsebenzi ukunemba ngokulinganayo ngokuqinisekile akufani ne-ballscrew. Kungani umshini wokuqopha wekhompiyutha uwumshini wokubekelwa phansi futhi intengo yomshini wokubekelwa phansi idlula isikulufu esiyimfihlo esibizayo. Isizathu sisodwa kuphela ukuze uthole isivinini sokucubungula ngokushesha ukuze uthuthukise ukusebenza kahle. Ngenxa yokuthi isikulufu sendlela egxilile yokuthwala ingxenye ende yebanga simisiwe, ngakho-ke lapho umshini wesikulufa usetha okuphakelayo kwesivinini esikhulu kuzoveza izinga elithile lomthelela ekugcineni. Uma inkinga ixazululwa ngesikulufu sokuhola esiqine ngokwanele, isikulufu sokuhola esidingekayo sizoba phezulu ngentengo futhi kudingeka ukuthi sifakwe amandla anele ukushayela injini. Isicelo se-rack senza lokhu kuntuleka. Ngoba i-rack iyingxenye egxilile ngokuphelele emzimbeni wenani elincane, kanye nesakhiwo sokubeka eceleni kwendlela yokuqinisekisa ukuzinza kwe-. Futhi ngenxa yokuthi isethi yamamotho angu-2 no-2, inani libiza kancane kune-screw, kodwa intengo ingcono kakhulu kunesikulufu sokuhola esiqinile kanye nenjini yokushayela enkulu. Kodwa ukunemba kungaphezu kokucaciswa kwesikulufu esingaphansi kancane kunomshini wokuqopha wekhompyutha osetshenziswa kuyo, ingilazi ephilayo / impahla yokukhangisa / Ukwenza ukhuni / ifenisha / ukucubungula imabula, ngikholelwa ukuthi ukufinyelela 0.05mm ukunemba ngokwanele ukuhlangabezana nezidingo ze. Lena indawo yokubeka imishini yokudala isidingo semakethe.
I-Helical rack kanye ne-pinion transmission izinzile kakhulu kune-rack rack kanye ne-pinion, enobubanzi obufanayo be-helical racks, i-helical pinion ne-rack isebenza kahle kakhulu kune-rack rack ne-pinion, kodwa ukusetshenziswa okusebenzayo esakhiweni sokubeka mpo kungaphezulu kakhulu kwe-helical rack. Lokhu kungenxa yokuthi:
① Ukuhanjiswa kwerack eqondile kulula ekwenziweni kwemishini, ukufakwa kanye nokususa iphutha.
② Usayizi ofanayo, impahla yokubeka mpo kanye pinion processing izindleko inqobo nje uma 1/2-1/3 izindleko ze-helical rack kanye ne-pinion processing.
③ I-Helical rack kanye ne-pinion processing noma ukufakwa akukho endaweni, khona-ke umphumela mubi kune-rack eqondile kanye ne-pinion.
Ngakho-ke, empeleni, ngaphezu kwezidingo eziphakeme, noma isakhiwo somthwalo osindayo sisekusetshenzisweni kwe-helical rack kanye ne-pinion transmission, i-general isetshenziswa i-rack rack kanye ne-pinion transmission. Futhi abanye osomabhizinisi abangathembekile benza indawo yokuthengisa ye-Helical rack ne-pinion, empeleni, basebenzisa i-Helical rack ne-pinion ephansi esikhundleni salokho.. Lokhu kuzokwenza kuphela okuphambene. Manje STYLECNC Kunconywa ukuthi ungaphuphutheki i-Helical rack ne-pinion.
2. Ukudluliselwa kwe-Ballscrew.
① Idivayisi yokudlulisa i-Ballscrew yamathuluzi omshini nemishini enembayo, esetshenziswa kakhulu, umsebenzi wayo oyinhloko ukuguqula ukunyakaza okujikelezayo kube ukunyakaza okuqondile, noma i-torque iguqule i-axial iphoqelele ngokuphindaphindiwe, inakho kokubili ukunemba okuphezulu nezici ezihlehliswayo nezisebenza kahle.
② I-Ballscrew yenziwe ngesikulufu, inathi nebhola. Umsebenzi wayo ukuguqula ukunyakaza okujikelezayo kube ukunyakaza okuqondile, okuwukunwetshwa okuqhubekayo nokuthuthukiswa kwama-Ballscrew, ukubaluleka okubalulekile kwalokhu kuthuthukiswa ukuhambisana nesenzo sokugingqika sibe isenzo sokushelela. I-Ballscrew isetshenziswa kakhulu kuzo zonke izinhlobo zemishini yezimboni kanye nezinsimbi ezinembayo ngenxa yokumelana okuncane kakhulu kokungqubuzana.
③ Izici ze-Ballscrew:
a. Uma kuqhathaniswa nesikulufu esishelelayo / se-trapezoidal, i-torque yokushayela ingu-1/3.
Ngoba kunamabhola amaningi ku-Ballscrew shaft kanye ne-screw nut ukwenza ukunyakaza okugoqayo, ukuze ithole ukusebenza kahle okuphezulu. Uma kuqhathaniswa ne-torque ye-screw eholayo eslayidayo eyedlule iye ku-1/3 ngezansi, okungukuthi, ukuzuza ukunyakaza okufanayo kwamandla adingekayo ukuze kusetshenziswe amandla okusebenzisa isikulufa esigoqayo esingu-1/3. Iwusizo ekongeni ugesi.
b. Okuphakelayo okuncane kungenzeka.
I-Ballscrew pair iwukusetshenziswa kokunyakaza kwebhola, ngakho-ke i-torque yokuqala incane kakhulu, ngeke kube khona ukunyakaza kokuslayida kwento ekhasayo, ingaqinisekisa ukugcwaliseka kokuphakelayo okuncane okunembile.
c. Isiqinisekiso sokunemba okuphezulu.
Ballscrew ikhiqizwa ezingeni eliphakeme kakhulu emhlabeni imishini kanye nemishini ukuhambisana kusukela Japan, ikakhulukazi ukugaya, umhlangano, hlola inqubo yemvelo ifektri, phezu izinga lokushisa kanye nomswakama zazilawulwa ngokuqinile, ngenxa ephelele uhlelo ukuphathwa izinga ukwenza ukunemba kungenziwa okuqinisekisiwe ngokugcwele.
d. Okuphakelayo ngesivinini esiphezulu kungenzeka.
Ngenxa yokusebenza kahle okuphezulu nokushisa okuphansi, i-Ballscrew ingenziwa ngesivinini esikhulu.
e. Akukho ukuhlehla, ukuqina okuphezulu.
I-Ballscrew ingangezwa kungcindezi, ngenxa yengcindezi i-axial clearance ingafinyelela kumanani angemahle, futhi ithole ukuqina okuphezulu (ngaphakathi kwe-Ballscrew ukuya ebholeni kanye nengcindezi yangaphambili, lapho ukusetshenziswa kwangempela kwamadivaysi emishini, ngenxa yebhola lamandla eliphikisayo lingathuthukisa ukuqina kwe-screw nut).
3. Isikulufu sokuhola sohlobo lwesitebhisi sedrayivu sokuhola sakhiwe yisikulufu, inathi nebhola, ukunyakaza okuzungezayo kube ukunyakaza okulandelanayo, noma ukunyakaza ngomugqa kube ukunyakaza okujikelezayo kwezingxenye ezifanele zokudlulisela. Isikulufu sokuhola sisetshenziswa kakhulu kuzo zonke izinhlobo zemishini yezimboni namathuluzi anembayo ngenxa yokumelana kwaso okuncane okungqubuzana. Ngaphambilini imishini esetshenziswe ku-screw trapezoidal, ngoba inamandla omthwalo omuhle nokuzinza, kodwa ngokuqhubeka kobuchwepheshe bokucubungula, amandla okuthwala i-Ballscrew kanye nokuzinza kancane kancane kuthathe indawo yesikulufu se-trapezoidal, kuyilapho ngesikhathi esifanayo ukuba nesikulufa se-trapezoidal asinakho ukunemba okuphezulu futhi ikhono lokubuyisela umlilo limpofu. Ngakho-ke manje imishini evamile yezimboni ku-Ballscrew ngokuyisisekelo ithathe indawo yesikulufu se-trapezoidal.
