Imipaka ntarengwa yo kubara formula d-ges-Td nubunini bwibanze bwa diameter nkuru yumurongo - gutandukana kwa datum - kwihanganira.
Urugero: M8 urudodo rwo hanze 6g urwego runini rwa diameter ntarengwa agaciro ntarengwa φ8-0.028 = φ7.972.
Agaciro ntarengwa φ8-0.028-0.212 = φ7.76
Icyitonderwa: diameter Diameter nini yurudodo igenwa na diametre yurudodo rwometseho urudodo hamwe nurwego rwo kumenyo yinyo yambara yumudozi uzunguruka isahani / uruziga, kandi agaciro kayo kangana na diametre yumurongo wurudodo rushingiye kuri ibikoresho bimwe bitunganijwe kandi bitunganijwe. Nukuvuga ko, niba diameter yo hagati ari nto, diameter nini izaba nini, naho ubundi niba diameter yo hagati ari nini, diameter nini izaba nto.
② Kubice bisaba kuvura ubushyuhe no kuvura hejuru, hitawe kubikorwa byo gutunganya, diameter yumurongo igomba kugenzurwa kugirango irenze urugero rwo hasi rwicyiciro cya 6h hiyongereyeho 0.04mm mugihe cyo kubyara nyirizina. Kurugero, umugozi wo hanze wa M8 urimo gukwega (kuzunguruka) Diameter nkuru yinsinga igomba kuba hejuru ya 7.83 no munsi ya 7.95.
4. Kubara no kwihanganira diameter yimbere
a. Ingano shingiro yo kubara urudodo rwimbere diameter nto (D1)
Ingano yibanze = ubunini bwibanze bwurudodo rwimbere - ikibanza × coefficient
Urugero: Diameter yibanze yumutwe wimbere M8 ni 8-1.25 × 1.0825 = 6.646875≈6.647
b. Kubara kwihanganira diameter ntoya (ishingiye ku kibanza) hamwe na diameter ntoya ya 6H y'imbere
P0.8 +0. 2 P1.0 +0. 236 P1.25 +0.265 P1.5 +0.3 P1.75 +0.335
P2.0 +0.375 P2.5 +0.48
Inzira ntarengwa yo gutandukana ya 6H urwego rwimbere D1 + HE1 nubunini bwibanze bwurudodo rwimbere diameter nto + gutandukana.
Icyitonderwa: Kugabanuka kubogamye kurwego rwa 6H ni “0 ″
Inzira yo kubara kumurongo wo hejuru wurwego rwa 6H urwego rwimbere ni = D1 + HE1 + TD1, nubunini bwibanze bwa diameter ntoya yumutwe wimbere + gutandukana + kwihanganira.
Urugero: Umupaka wo hejuru wa diameter ntoya ya 6H urwego M8 urudodo rwimbere ni 6.647 + 0 = 6.647
Umupaka wo hasi wa diameter ntoya ya 6H urwego M8 urudodo rwimbere ni 6.647 + 0 + 0.265 = 6.912
c. Kubara gutandukana shingiro rya diameter ntoya yumutwe wimbere 6G urwego (ukurikije ikibuga) nagaciro gato ka diameter
P0.8 +0.024 P1.0 +0.026 P1.25 +0.028 P1.5 +0.032 P1.75 +0.034
P2.0 +0.038 P2.5 +0.042
Inzira yumupaka wo hasi wa diameter ntoya ya 6G urwego rwimbere = D1 + GE1, nubunini bwibanze bwurudodo rwimbere + gutandukana.
Urugero: Umupaka wo hasi wa diameter ntoya ya 6G urwego M8 urudodo rwimbere ni 6.647 + 0.028 = 6.675
Imipaka ntarengwa yo hejuru ya 6G urwego M8 rwimbere rwimbere diameter D1 + GE1 + TD1 nubunini bwibanze bwurudodo rwimbere + gutandukana + kwihanganira.
Urugero: Umupaka wo hejuru wa diameter ntoya ya 6G urwego M8 urwego rwimbere ni 6.647 + 0.028 + 0.265 = 6.94
Icyitonderwa: height Uburebure bwikibanza cyurudodo rwimbere bufitanye isano itaziguye nigihe cyo kwikorera umutwaro wurudodo rwimbere, bityo rero bigomba kuba mumipaka yo hejuru yicyiciro cya 6H mugihe cyo kubyara ubusa.
② Mugihe cyo gutunganya imigozi yimbere, ntoya ya diameter yumurongo wimbere bizagira ingaruka kumikoreshereze yimikorere yimashini - kanda. Urebye kubikoresha, ntoya ya diameter, nibyiza, ariko iyo urebye neza, diameter ntoya ikoreshwa muri rusange. Niba ari icyuma cyangwa aluminiyumu, umupaka wo hasi ugana hagati ya diameter nto ugomba gukoreshwa.
Diametero ntoya yumutwe wimbere 6G irashobora gushyirwa mubikorwa nka 6H mubikorwa byubusa. Urwego rwukuri rusuzuma cyane cyane igipfundikizo cyumurambararo wa diameter. Kubwibyo, gusa diameter yikibanza cya robine irasuzumwa mugihe cyo gutunganya urudodo utitaye kuri diameter ntoya yumwobo.
5. Kubara formula yuburyo bumwe bwo kwerekana umutwe
Ibiharuro byo kubara uburyo bumwe bwo kwerekana: n = 40 / Z.
n: numubare wa revolisiyo umutwe ugabanya ugomba guhinduka
Z: agace kangana k'akazi
40: Umubare uhamye wo kugabana umutwe
Urugero: Kubara urusyo rwa mpandeshatu
Gusimbuza formula: n = 40/6
Kubara: ① Koroshya agace: Shakisha uduce duto duto 2 hanyuma uyigabanye, ni ukuvuga kugabanya umubare numubare 2 icyarimwe kugirango ubone 20/3. Mugihe ugabanya igice, ibice byacyo bingana ntigihinduka.
Kubara agace: Muri iki gihe, biterwa n'indangagaciro z'umubare n'umubare; niba umubare numubare munini, ubare.
20 ÷ 3 = 6 (2/3) nigiciro n, ni ukuvuga, umutwe ugabana ugomba guhinduka inshuro 6 (2/3). Muri iki gihe, agace kahindutse umubare uvanze; igice cyuzuye cyumubare uvanze, 6, numubare ugabanya Umutwe ugomba guhinduka 6 byuzuye. Igice 2/3 hamwe nigice gishobora kuba 2/3 gusa cyumurongo umwe, kandi bigomba kubarwa muriki gihe.
Kubara guhitamo icyapa cyerekana: Kubara uruziga ruri munsi yumuzingi bigomba kugerwaho hifashishijwe icyapa cyerekana urutonde rwumutwe. Intambwe yambere yo kubara nukwagura igice 2/3 icyarimwe. Kurugero: niba igice cyaguwe inshuro 14 icyarimwe, igice ni 28/42; niba yaguwe inshuro 10 icyarimwe, amanota ni 20/30; niba yaguwe inshuro 13 icyarimwe, amanota ni 26/39… Kwagura amarembo yo kugabana bigomba gutoranywa ukurikije umubare wibyobo biri ku cyapa.
Muri iki gihe ugomba kwitondera:
NumberUmubare wibyobo byatoranijwe kubisahani byerekana ibimenyetso bigomba kugabanywa 3. Urugero, murugero rwabanjirije iki, imyobo 42 ni inshuro 14 inshuro 3, 30 imyobo ni inshuro 10, 39 ni 13 inshuro 3…
Kwaguka kwagace kagomba kumera nkumubare numubare wagutse icyarimwe kandi ibice byabo bingana ntibihinduka, nkurugero
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)
Ikigereranyo 42 kuri 28/42 cyerekanwe hifashishijwe ibyobo 42 byumubare; numero 28 iri imbere kumwobo uhagaze wuruziga rwo hejuru hanyuma ikazenguruka mu mwobo wa 28, ni ukuvuga ko umwobo 29 ariwo mwobo uhagaze wiziga ryubu, naho 20/30 ni 30 30 Icyapa cyerekana icyerekezo cyerekejwe imbere n'umwobo wa 10 cyangwa umwobo wa 11 niwo mwobo uhagaze wa epicycle. 26/39 ni umwobo uhagaze wa epicycle nyuma yicyapa 39 cyerekana umwobo werekeza imbere naho umwobo wa 26 nuwobo wa 27.

Abakora ibikoresho bya CNC - Ubushinwa CNC Uruganda & Abaguzi (xinfatools.com)
Iyo usya kare kare (ibice bitandatu bingana), urashobora gukoresha imyobo 42, imyobo 30, imyobo 39 nibindi byobo bigabanijwe neza na 3 nkibipimo: igikorwa ni uguhindura ikiganza inshuro 6, hanyuma ukajya imbere kumwanya umwobo w'uruziga rwo hejuru. Noneho hindura 28 + 1/10 + 1/26+! umwobo kugeza ku ya 29/11/27 nk'umwobo uhagaze wa epicycle.
Urugero rwa 2: Kubara gusya ibikoresho 15 byinyo.
Gusimbuza formula: n = 40/15
Kubara n = 2 (2/3)
Hindura uruziga 2 rwuzuye hanyuma uhitemo umwobo werekana kugabanywa na 3, nka 24, 30, 39, 42.51.54.57, 66, nibindi. Noneho uhindukire imbere kuri plaque ya orifice 16, 20, 26, 28, 34, 36, 38 , 44 Ongeramo umwobo 1, aribyo umwobo 17, 21, 27, 29, 35, 37, 39, na 45 nkibyobo bya epicycle.
Urugero rwa 3: Kubara indangagaciro yo gusya amenyo 82.
Gusimbuza formula: n = 40/82
Kubara n = 20/41
Nukuvuga: gusa hitamo isahani yerekana ibimenyetso 41, hanyuma uhindure umwobo 20 + 1 cyangwa 21 kumurongo wo hejuru uhagaze nkumwobo uhagaze wuruziga.
Urugero rwa 4: Kubara indangagaciro yo gusya amenyo 51
Simbuza formula n = 40/51. Kubera ko amanota adashobora kubarwa muri iki gihe, urashobora guhitamo mu buryo butaziguye umwobo, ni ukuvuga, hitamo icyapa cyerekana 51, hanyuma uhindure imyobo 51 + 1 cyangwa 52 ku mwobo wo hejuru uhagaze nk'umwobo uhagaze . Nibyo.
Urugero rwa 5: Kubara indangagaciro yo gusya amenyo 100.
Gusimbuza formula n = 40/100
Kubara n = 4/10 = 12/30
Nukuvuga, hitamo isahani 30 yerekana isahani, hanyuma uhindure umwobo wa 12 + 1 cyangwa 13 kumurongo wo hejuru uhagaze nkumwobo uhagaze wiziga ryubu.
Niba ibyapa byose byerekana bidafite umubare wibyobo bisabwa kugirango ubare, uburyo bwo kugereranya ibipimo bigomba gukoreshwa mu kubara, bitashyizwe muri ubu buryo bwo kubara. Mu musaruro nyirizina, ibikoresho byo kwifashisha bikoreshwa muri rusange, kubera ko ibikorwa nyirizina nyuma yo kubara ibipimo fatizo bibarwa bitoroshye.
