Ifektri ethengisa ngokwezifiso ze-tungsten carbide spiral bevel gear milling cutters iyathengiswa

Kunemigodi eminingi emincane endaweni yezinyo ukwenza unqenqema lokusika, futhi ithuluzi lomshini wegiya elimise okwegiya lisetshenziselwa umshini womsebenzi ngokuya ngesimiso se-helical gear meshing. Ngesikhathi sokucutshungulwa, ithuluzi lisika ama-chips amahle afana nentshebe endaweni yezinyo legiya, ngakho libizwa ngokuthi i-gear cutter yokushefa. Izisiki zokugunda amagiya zisetshenziselwa ukuqedela amazinyo egiya ngemva kokuphonswa kwegiya nokubunjwa kwegiya (bona ukucutshungulwa kwegiya). I-disc-shaving cutter yegiya evame ukusetshenziswa ifana negiya eliqinile le-helical cylindrical (Umfanekiso 1). I-groove ebusweni bezinyo inamafomu amabili: enye iwukuthi iphasi eliyindilinga noma elivunguzayo livulwa kuyo yonke indandatho yegiya. Ingxenye yesiphambano se-groove ingaba unxande noma i-trapezoidal. Lesi sisiki sokushefa silola kuphela ubuso bangaphambili (umsele) ngemva kokuba buthuntu. Ilungele ukushefa abasiki nge-modulus engaphansi kuka-1.75 mm; enye iwukuthi ama-groove ezinhlangothini zombili awahambeki, afakwa ngokuhlukana nokufaka okumise okwekama. Ukuze wenze ukufakwa kungaba ukuhoxisa ummese, ibekwe empandeni izinyo ngalinye. Geza izimbobo ezitshekile. Ngemuva kokuthi lolu hlobo lokusika ukushefa lubuthuntu, ludinga ukugaya kabusha iphrofayili yamazinyo kanye ne-cylindrical surface of the tooth top. Umbese wokushefa
Ukuze kuncishiswe umthwalo wokusika wezinyo ngalinye, inani lamazinyo omsiki wegiya likhulu, futhi inombolo eyinhloko ngokuvamile isetshenziselwa ukugwema into evamile ngenani lamazinyo egiya elizosikwa, ngaphandle kwalokho iphutha. yokusika igiya lokushefa kuzokopishwa egiyeni elizocutshungulwa. Ngokwezindinganiso zamazwe ngamazwe, ukunemba kwabasiki begiya bokushefa kunezinhlobo ezintathu: AA, A kanye no-B. Ekukhiqizweni kwangempela, ukushefa kwephrofayili yezinyo legiya ngesisiki esilungile sokushefa sephrofayili yezinyo ngokuvamile sichezuka emugqeni olungile oseduze nomjikelezo wephimbo. igiya, futhi ihlehliswa phakathi, ngokuchezuka okungaba ngu-0.01 kuya ku-0.03 mm. Ukuchezuka kwephrofayili yezinyo kwamagiya e-spur kukhulu kunaleyo yamagiya e-helical. Ukuze uthole iphrofayili yezinyo elifanele le-workpiece, iphrofayili yamazinyo yomsiki wokushefa kufanele ilungiswe. Ekukhiqizeni ngobuningi, ijika lokulungisa iphrofayili yezinyo lomsiki wokushefa linqunywa izindlela zokuhlola.
I-gear shaving cutter ingacubungula amagiya angama-cylindrical angaphakathi nangaphandle aqondile nangaphandle, ngokusebenza kahle okuphezulu kokukhiqiza kanye nendawo ebushelelezi. Ngaphezu kwalokho, kukhona nabasiki begiya lezikelemu ukuze kucutshungulwe amagiya ezikelemu. Uhlobo kanye nemingcele yegiya lezikelemu eziyisisekelo kufanele kufane negiya lezikelemu elisebenzayo elihambisana negiya lezikelemu. Njengesisiki segiya sokushefa, sinemifantu eminingi emincane endaweni ezungezayo ukuze yakhe unqenqema lokusika futhi iqukethe ama-chips. Izinqamuleli zokushefa izikelemu zinzima ukwenza futhi zisetshenziswa kuphela uma kwenziwa amagiya ezikelemu adinga ukunemba okuphezulu.
