③ Ububanzi obuncane bentambo yangaphakathi engu-6G bungasetshenziswa njengo-6H ekukhiqizeni okungenalutho. Izinga lokunemba ngokuyinhloko licabangela ukumbozwa kobubanzi bephimbo bomucu. Ngakho-ke, ububanzi be-pitch kuphela bompompi bucatshangelwa ngesikhathi sokucubungula intambo ngaphandle kokucabangela ububanzi obuncane bembobo yokukhanya.
5. Ifomula yokubala yendlela yokukhomba eyodwa yekhanda lokukhomba
Ifomula yokubala yendlela yokukhomba eyodwa: n=40/Z
n: inombolo yokuguquguquka okufanele ukuphenduka kwekhanda elihlukanisayo
Z: ingxenye elinganayo ye-workpiece
40: Inombolo egxilile yekhanda elihlukanisayo
Isibonelo: Ukubalwa kokugaya okuyi-hexagonal
Faka esikhundleni sefomula: n=40/6
Ukubala: ① Yenza kube lula ingxenyenamba: Thola isihlukanisi esincane kakhulu esingu-2 futhi usihlukanise, okungukuthi, hlukanisa inombolo nedenominator ngo-2 ngesikhathi esifanayo ukuze uthole u-20/3. Ngenkathi kunciphisa ingxenye, izingxenye zayo ezilinganayo zihlala zingashintshiwe.
② Bala ingxenyenamba: Ngalesi sikhathi, kuya emananini enumerator kanye nedenominator; uma inombolo nedenominayitha inkulu, bala.
20÷3=6(2/3) inani lika-n, okungukuthi, ikhanda elihlukanisayo kufanele liguqulwe izikhathi ezingu-6(2/3). Ngalesi sikhathi, ingxenyenamba isiphenduke inombolo exubile; ingxenye ephelele yenombolo exubile, 6, inombolo ehlukanisayo Inhloko kufanele iphendule amajika ayi-6 agcwele. Ingxenye engu-2/3 eneqhezu ingaba ngu-2/3 kuphela wethuba elilodwa, futhi kufanele ibalwe kabusha ngalesi sikhathi.
③ Ukubalwa kokukhethwa kwepuleti lokukhomba: Ukubalwa kombuthano ongaphansi kowodwa kufanele kubonakale ngosizo lwepuleti lokukhomba lekhanda lokukhomba. Isinyathelo sokuqala ekubaleni ukukhulisa ingxenyenamba engu-2/3 ngesikhathi esifanayo. Isibonelo: uma ingxenyenamba inwetshwa izikhathi ezingu-14 ngesikhathi esifanayo, ingxenye ingu-28/42; uma inwetshwa izikhathi ezingu-10 ngesikhathi esifanayo, amaphuzu angu-20/30; uma inwetshwa izikhathi ezingu-13 ngesikhathi esifanayo, amaphuzu angu-26/39… Ukuphindaphinda kokunwetshwa kwesango elihlukanisayo kufanele kukhethwe ngokwenani lezimbobo ku-indexing plate.
Ngalesi sikhathi kufanele unake:
①Inani lezimbobo ezikhethelwe ipuleti lokukhomba kufanele lihlukaniseke idinominetha engu-3. Isibonelo, esibonelweni sangaphambilini, izimbobo ezingu-42 zingu-14 izikhathi 3, izimbobo ezingu-30 zingu-10 izikhathi 3, 39 izikhathi ezingu-13 3…
② Ukunwetshwa kwengxenye kufanele kube ngendlela yokuthi inombolo nedenominetha zinwetshwe kanyekanye futhi izingxenye zazo ezilinganayo zihlale zingashintshiwe, njengakusibonelo.
28/42=2/3×14=(2×14)/(3×14); 20/30=2/3×10=(2×10)/(3×10);
26/39=2/3×13=(2×13)/(3×13)
I-denominator 42 ka-28/42 ikhonjiswe kusetshenziswa izimbobo ezingama-42 zenombolo yenkomba; inombolo engu-28 ibheke phambili embotsheni yokuma yesondo eliphezulu bese izungeza embobeni engama-28, okungukuthi, imbobo engu-29 iyimbobo yokuma yesondo lamanje, futhi u-20/30 uku-30 Ipuleti lokukhomba imbobo liphendulelwa phambili. futhi umgodi we-10 noma umgodi we-11 uwumgodi wokuma we-epicycle. I-26/39 iyimbobo yokuma ye-epicycle ngemva kokuba ipuleti lokukhomba elinezimbobo ezingu-39 liphendulelwe phambili futhi imbobo engu-26 ingumgodi wama-27.
Amathuluzi e-Xinfa CNC anezici zekhwalithi enhle nenani eliphansi. Ukuze uthole imininingwane, sicela uvakashele:
Abakhiqizi Bamathuluzi E-CNC - Imboni Yamathuluzi Yase-China CNC Nabahlinzeki (xinfatools.com)
Lapho ugaya izikwele eziyisithupha (izingxenye eziyisithupha ezilinganayo), ungasebenzisa izimbobo ezingama-42, izimbobo ezingama-30, izimbobo ezingama-39 nezinye izimbobo ezihlukaniswe ngokulinganayo ngo-3 njengezinkomba: umsebenzi uwukuguqula isibambo izikhathi eziyisi-6, bese uqhubekela phambili endaweni ebekiwe. izimbobo zesondo eliphezulu. Bese uvula i-28+1/ 10+1 / 26+! umgodi we-29/11/27 imbobo njengomgodi wokuma we-epicycle.

Bese ujikela phambili ku-orifice plate 16, 20, 26, 28, 34, 36, 38 , 44 Engeza imbobo engu-1, okuyizimbobo 17, 21, 27, 29, 35, 37, 39, kanye no-45 njengezimbobo zokuma ze-epicycle.
Isibonelo sesi-3: Ukubalwa kwenkomba yokugaya amazinyo angama-82.
Faka esikhundleni sefomula: n=40/82
Bala n=20/41
Okungukuthi: vele ukhethe ipuleti lokukhomba elinezimbobo ezingu-41, bese uvula izimbobo ezingu-20+1 noma ezingu-21 embobeni yokumisa isondo eliphezulu njengembobo yokuma yesondo lamanje.
Isibonelo sesi-4: Ukubalwa kwenkomba yokugaya amazinyo angama-51
Faka esikhundleni sefomula n=40/51. Njengoba amaphuzu angenakubalwa ngalesi sikhathi, ungakhetha kuphela imbobo ngokuqondile, okungukuthi, khetha ipuleti lokukhomba elinezimbobo ezingu-51, bese uvula izimbobo ezingu-51+1 noma ezingu-52 embobeni yokumisa isondo eliphezulu njengembobo yamanje yokumisa isondo. . Leyo.
Isibonelo sesi-5: Ukubalwa kwenkomba yokugaya amazinyo ayi-100.
Faka esikhundleni sefomula n=40/100
Bala n=4/10=12/30
Okusho ukuthi, khetha ipuleti lokukhomba elinezimbobo ezingu-30, bese uvula izimbobo ezingu-12+1 noma ezingu-13 embobeni yokumisa isondo eliphezulu njengembobo yokuma yesondo lamanje.
Uma wonke ama-indexing plate engenalo inani lezimbobo ezidingekayo ekubaleni, indlela yokuhlanganisa inkomba kufanele isetshenziselwe ukubala, engafakiwe kule ndlela yokubala. Emkhiqizweni wangempela, i-gear hobbing ngokuvamile isetshenziswa, ngoba ukusebenza kwangempela ngemva kokubalwa kwenkomba ehlanganisiwe akulula kakhulu.
