Chii chinonzi geometric tolerances

ISO inotsanangura kushivirira kwejometri se "Geometrical product specifications (GPS)−Geometrical tolerancing-Kushivirira kwechimiro, kutarisika, nzvimbo uye kupera".Nemamwe manzwi, "geometrical maitiro" zvinoreva chimiro, saizi, hukama hwenzvimbo, nezvimwe zvechinhu, uye "kushivirira" ndiko "kushivirira kukanganisa".Chimiro che "geometric tolerance" ndechekuti haisi kungotsanangura hukuru, asiwo kushivirira kwechimiro uye chinzvimbo.

 

Musiyano pakati pedimensional uye geometric tolerances:

Nzira dzekunyora madhizaini edhizaini dzinogona kukamurwa zvakanyanya muzvikamu zviviri: "dimensional tolerances" uye "geometric tolerances".Dimensional tolerances inodzora urefu hwechikamu chimwe nechimwe.

Geometric tolerances kudzora chimiro, parallelism, kurerekera, chinzvimbo, runout, zvichingodaro.

Geometric kushivirira kudhirowa

 

Zvinoreva "ve nechokwadi chekuti nzvimbo A haipfuure parallelism ye0.02".

Sei uchifanira kumaka kushivirira kwejometri?

Semuyenzaniso, pakuhodha ndiro chikamu, mugadziri akataura kushivirira kwepazasi.

A Band yekushivirira

Zvisinei, maererano nemifananidzo iri pamusoro, mugadziri anogona kupa zvikamu izvi.

 

A Band yekushivirira

Zvikamu zvinogona kuve zvisina kukodzera kana kukanganisa kana parallelism isina kumakwa padhirowa.

Mugadziri haana mhosva, asi pane kushivirira kwemugadziri kucherekedza.Mifananidzo yechikamu chimwe chete chakaiswa nejiometri kushivirira zvinogona kukonzera dhizaini inoratidzwa pazasi.Ruzivo rwekushivirira kwejometri, senge "parallelism" uye "planarity", inowedzerwa kumufananidzo zvichienderana neruzivo rwekuyera.Izvi zvinobatsira kudzivirira matambudziko anokonzerwa nekungomaka dimensional tolerances.

Kupfupisa, kushandisa geometric kushivirira kunogona kubudirira uye nekukurumidza kuratidza izvo mugadziri anoda, izvo zvingave zvisingakwanisi ne dimensional kushivirira.

 

 

Tsanangudzo mu ISO

Kubatana pakati pehukuru uye chimiro kunotsanangurwa seizvi:

 

Zvinyorwa mu ISO8015-1985izvo zvinoratidzwa mumapurani, sehukuru uye zvimiro zvisingakwanisi, hazvienderane nehumwe hukuru, miganhu, kana hunhu uye zvinoshanda zvega kunze kwekunge zvatsanangurwa neimwe nzira.

 

 

Sezvambotaurwa, musimboti wekuzvimiririra chiyero chepasi rose chinotsanangurwa neISO.Nekudaro, mamwe makambani eUS anogona kusatevedzera mutemo wekuzvimiririra zvinoenderana neASME (American Society of Mechanical Engineers) nhungamiro.Kuti udzivise chero nyonganiso panguva yekutengeserana nemakambani ekunze, zvinokurudzirwa kutaurirana uye kujekesa zvinodiwa zvemataurirwo zvisati zvaitika.
