Kushata kwepamusoro ndiyo yakakosha tekinoroji indekisi inoratidza kukanganisa kwemicrogeometric kwechikamu chepamusoro uye chinhu chakakosha pakuongorora kunaka kwepasi. Kusarudzwa kwekuoma kwepamusoro kwakabatana zvakananga nemhando yechigadzirwa, hupenyu hwesevhisi, uye mutengo wekugadzira.
Pane nzira nhatu dzekusarudza kushata kwepamusoro kwezvikamu zvemakanika: nzira yekuverenga, nzira yekuyedza, uye nzira yekufananidza. Iyo yekufananidza nzira inowanzoshandiswa mumakanika chikamu dhizaini nekuda kwekureruka kwayo, kumhanya, uye kushanda. Zvinyorwa zvakakwana zvekutaura zvinodikanwa pakushandiswa kwenzira yekufananidza, uye mechanical design manual inopa ruzivo rwakakwana uye mabhuku. Chinonyanya kushandiswa chinongedzo ndeyekushata kwepamusoro kunoenderana nekirasi yekushivirira.
Kazhinji, mativi emakanika ane diki dimensional kushivirira zvinodiwa ane madiki epamusoro roughness kukosha, asi hapana yakagadziriswa inoshanda hukama pakati padzo. Semuyenzaniso, mamwe mativi emuchina, akadai sezvibato, zviridzwa, midziyo yehutsanana, uye muchina wechikafu, anoda nzvimbo dzakatsetseka kwazvo dzine hutsinye hwepamusoro, nepo zvinodiwa zvekushivirira zvakaderera. Kazhinji, pane kumwe kunyorerwa pakati pegiredhi rekushivirira uye kukosha kwehukukutu hwezvikamu zvine dimensional kushivirira zvinodiwa.
Mazhinji emakanika zvikamu zvekugadzira zvinyorwa uye ekugadzira monographs anosuma empirical calculation mafomula ekuoma kwepamusoro uye hukama hwekushivirira kwezvikamu zvemakina. Zvisinei, hutsika muzvinyorwa zvinopiwa zvinowanzosiyana, zvichikonzera kuvhiringidzika kune avo vasina kujairana nemamiriro ezvinhu uye kuwedzera kuoma kwekusarudza kushata kwepamusoro kune zvikamu zvemakanika.
Mune mazwi anoshanda, mhando dzakasiyana dzemakina dzine zvinosiyana zvinodiwa pakushata kwepamusoro kwezvikamu zvadzo, kunyangwe kana vaine kushivirira kwakafanana. Izvi zvinokonzerwa nekugadzikana kwekukodzera. Mukugadzira uye kugadzira maitiro emakanika zvikamu, izvo zvinodikanwa zvekugadzikana kwekubatana uye kuchinjana kwezvikamu zvinosiyana zvichienderana nerudzi rwemuchina. Aripo mamechani zvikamu dhizaini zvinyorwa zvinoratidza anotevera matatu makuru marudzi:
Precision Machinery:Rudzi urwu runoda kugadzikana kwepamusoro kwekukodzera uye kuraira kuti kupera kwekupfeka kwezvikamu hakupfuuri 10% yehuwandu hwekushivirira kukosha, kungave panguva yekushandiswa kana mushure memagungano akawanda. Inonyanya kushandiswa pamusoro pezviridzwa zvine hunyanzvi, mageji, maturusi ekuyeresa chaiwo, uye kukwesha kwepamusoro kwezvikamu zvakakosha zvakaita semukati mesilinda, bhuku guru rematurusi emuchina, uye jenari huru yemuchina unobhowa. .
Zvakajairika Precision Machina:Ichi chikamu chine zvidikanwi zvepamusoro zvekugadzikana kwekukodzera uye zvinoda kuti iyo yekupfeka yezvikamu haipfuure 25% yeiyo dimensional kushivirira kukosha. Inodawo nzvimbo yakavharwa yakavharwa uye inonyanya kushandiswa mumaturusi emuchina, maturusi, uye mabheji ekutenderedza kuti aenderane nepamusoro, maburi epini yepini, uye nzvimbo dzekubatana dzine hupamhi hwekufamba, senge nzvimbo yekubatana kweiyo inotsvedza uye. giya zino rinoshanda pamusoro.
General Machinery:Rudzi urwu runoda kuti muganho wekupfeka wezvikamu usapfuure 50% yehuremu hwekushivirira uye haisanganisi kufamba kwehukama hwekusangana kwenzvimbo.cnc milled zvikamu. Inoshandiswa kune zvinhu zvakaita semabhokisi evhavha, maoko, nzvimbo yekushanda yepasi, makiyi, makiyi anoda kuenderana nepedyo, uye nzvimbo dzekubatana dzine yakaderera hama yekumhanya, senge maburi emabhureki, mabhushi, uye nzvimbo dzekushanda dzine pulley shaft maburi. uye reducers.
Isu tinoita ongororo yehuwandu hweakasiyana tafura dhizaini mubhuku rekugadzira dhizaini, tichishandura chiyero chenyika chekare chekuoma kwepasi (GB1031-68) kuita chiyero chitsva chenyika (GB1031-83) muna 1983 tichitarisa kune yepasi rose standard ISO. Isu tinotora zviyero zvekuongorora zvakasarudzika, inova avhareji yekutsauka kukosha kwecontour arithmetic (Ra=(1/l)∫l0|y|dx). Yekutanga nhevedzano yehutsika inosarudzwa naRa inoshandiswa kuwana kuwirirana pakati peiyo roughness Ra uye dimensional kushivirira IT.
Kirasi 1: Ra≥1.6 Ra≤0.008×IT
Ra≤0.8Ra≤0.010×IT
Kirasi 2: Ra≥1.6 Ra≤0.021×IT
Ra≤0.8Ra≤0.018×IT
Kirasi 3: Ra≤0.042×IT
Tafura 1, Tafura 2, uye Tafura 3 inonyora mhando nhatu dziri pamusoro dzehukama.
Paunenge uchigadzira zvikamu zvemakanika, zvakakosha kuti usarudze kukosha kweiyo roughness zvichienderana neiyo dimensional kushivirira. Mhando dzakasiyana dzemakina dzinoda tafura dzakasiyana dzematafura kuti dzisarudzwe.
Izvo zvakakosha kucherechedza kuti tafura inoshandisa yekutanga nhevedzano kukosha kweRa, nepo yekare yenyika chiyero inoshandisa yechipiri nhevedzano kukosha kweiyo muganho kukosha kweRa. Panguva yekutendeuka, panogona kunge paine nyaya dzine huwandu hwepamusoro uye hwakaderera. Isu tinoshandisa iyo yepamusoro kukosha mutafura nekuti inobatsira kuvandudza chigadzirwa chemhando, uye iyo yakaderera kukosha inoshandiswa kune yega tsika.
Tafura inoenderana negiredhi rekushivirira uye kushata kwepasi kweiyo yekare chiyero chenyika ine zvinhu zvakaomarara uye chimiro. Kune imwechete yekushivirira giredhi, saizi chikamu, uye saizi yekutanga, iyo roughness yepasi kukosha kwegomba uye shaft inosiyana, sezvinoita maitiro emhando dzakasiyana dzekukwana. Izvi zvinokonzerwa nehukama pakati pehutano hwekushivirira kwekare kushivirira uye yakakodzera chiyero (GB159-59) uye zvinhu zvataurwa pamusoro apa. Ikozvino kutsva kwenyika chiyero chekushivirira uye kukwana (GB1800-79) ine chiyero chakafanana chekushivirira kukosha kwega rega rekutanga mugiredhi rekushivirira uye chikamu chekukura, kurerutsa tafura inoenderana yegiredhi rekushivirira uye kushata kwepasi uye kuita kuti iwedzere zvesainzi uye zvine musoro.
Mubasa rekugadzira, zvakakosha kumisa sarudzo yekukasharara pamusoro pechokwadi chekuongorora kwekupedzisira uye kunyatsoongorora basa repamusoro uye.cnc kugadzira nzirahupfumi hwezvikamu zvechisarudzo chakanaka. Magiredhi ekushivirira uye hukasha hwepamusoro hwakapihwa mutafura inogona kushandiswa sereferensi yekugadzira.
