Kalasi Yovuta Kwambiri ndi Kulekerera: Kuyendetsa Ubale Wovuta Kwambiri mu Kuwongolera Ubwino

Kukula kwapamtunda ndi ndondomeko yofunikira yaukadaulo yomwe imawonetsa zolakwika zamtundu wa gawo ndipo ndizofunikira kwambiri pakuwunika kwapamwamba. Kusankhidwa kwa roughness pamwamba kumagwirizana mwachindunji ndi khalidwe la chinthu, moyo wautumiki, ndi mtengo wopangira.

Pali njira zitatu zosankhira kuuma kwa magawo amakina: njira yowerengera, njira yoyesera, ndi njira yofananira. Njira yofananira imagwiritsidwa ntchito kwambiri popanga gawo lamakina chifukwa cha kuphweka kwake, kuthamanga, komanso kuchita bwino. Zida zokwanira zofotokozera zimafunikira kuti agwiritse ntchito njira yofananira, ndipo zolemba zamakina zamakina zimapereka chidziwitso chokwanira komanso zolemba. Zomwe zimagwiritsidwa ntchito kwambiri ndizovuta zapamtunda zomwe zimagwirizana ndi gulu la kulolerana.

Nthawi zambiri, zida zamakina zokhala ndi zololera zazing'ono zazing'ono zimakhala ndi zolimba zocheperako, koma palibe mgwirizano wokhazikika pakati pawo. Mwachitsanzo, mbali zina zamakina, monga zogwirira, zida, zida zaukhondo, ndi makina opangira zakudya, zimafuna malo osalala kwambiri okhala ndi khwimbi lapamwamba, pomwe zofunikira zawo zololera ndizochepa. Childs, pali makalata ena pakati kulolerana kalasi ndi pamwamba roughness mtengo wa mbali ndi dimensional kulolerana zofunika.

Magawo ambiri amakanika amapangira zolemba ndikupangira ma monographs amayambitsa njira zowerengera zamakina zazovuta zapamtunda komanso ubale wololera wa magawo amakina. Komabe, zikhalidwe zomwe zili m'ndandanda zomwe zaperekedwa nthawi zambiri zimakhala zosiyana, zomwe zimachititsa chisokonezo kwa omwe sakudziwa momwe zinthu zilili komanso kumawonjezera vuto la kusankha kuuma kwapamwamba kwa ziwalo zamakina.

M'mawu othandiza, makina amitundu yosiyanasiyana ali ndi zofunikira zosiyanasiyana pazovuta zamtundu wa magawo awo, ngakhale atakhala ndi kulekerera kofanana. Izi ndichifukwa cha kukhazikika kwazomwezo. Pakupanga ndi kupanga magawo amakina, zofunika pakukhazikika kwa mating ndi kusinthana kwa magawo amasiyana malinga ndi mtundu wa makina. Zolemba zomwe zilipo kale zamakina zimawonetsa mitundu itatu iyi:

Makina Olondola:Mtundu uwu umafuna kukhazikika kwakukulu kwa kuyenerera ndi kulamula kuti malire ovala a zigawozo asapitirire 10% ya mtengo wololera, kaya pakugwiritsa ntchito kapena pambuyo pa misonkhano yambiri. Amagwiritsidwa ntchito kwambiri pamwamba pa zida zolondola, zoyezera, zida zoyezera mwatsatanetsatane, ndi kukangana kwa magawo ofunikira monga mkati mwa silinda, magazini yayikulu ya zida zamakina olondola, ndi magazini yayikulu yamakina otopetsa. .

Makina Okhazikika Okhazikika:Gulu ili liri ndi zofunikira zapamwamba kuti zikhale zokhazikika ndipo zimafuna kuti malire a mavalidwe a zigawozo asapitirire 25% ya mtengo wololera. Pamafunikanso osindikizidwa bwino kukhudzana pamwamba ndipo makamaka ntchito zida makina, zida, ndi kugubuduza mayendedwe kuti agwirizane pamwamba, taper pini mabowo, ndi malo kukhudzana ndi mkulu wachibale kuthamanga, monga mating pamwamba pa kutsetsereka ndi giya dzino ntchito pamwamba.

General Machinery:Mtundu uwu umafuna kuti malire ovala a magawo asapitirire 50% ya mtengo wololera ndipo samaphatikizapo kusuntha kwapang'onopang'ono kwa malo olumikizirana.cnc milled magawo. Amagwiritsidwa ntchito pazinthu monga zovundikira bokosi, manja, malo ogwirira ntchito pamwamba, makiyi, makiyi omwe amafunikira kuyandikira pafupi, ndi malo olumikizirana omwe ali ndi liwiro lotsika, monga mabowo a bulaketi, ma bushings, ndi malo ogwirira ntchito okhala ndi mabowo a pulley shaft. ndi ochepetsa.

Timasanthula ziwerengero zamitundu yosiyanasiyana yamatebulo mu bukhu la kamangidwe ka makina, kutembenuza mulingo wakale wadziko lapansi wa roughness (GB1031-68) kukhala mulingo watsopano wadziko (GB1031-83) mu 1983 molingana ndi muyezo wapadziko lonse lapansi wa ISO. Timatengera zoyezera zomwe timakonda, zomwe ndi mtengo wopatuka wa masamu a contour (Ra=(1/l)∫l0|y|dx). Mndandanda woyamba wa makhalidwe omwe amakondedwa ndi Ra amagwiritsidwa ntchito kuti apeze mgwirizano pakati pa roughness pamwamba Ra ndi dimensional tolerance IT.

Kalasi 1: Ra≥1.6 Ra≤0.008×IT
Ra≤0.8Ra≤0.010×IT
Kalasi 2: Ra≥1.6 Ra≤0.021×IT
Ra≤0.8Ra≤0.018×IT
Kalasi 3: Ra≤0.042×IT

Table 1, Table 2, and Table 3 tchulani maubwenzi omwe ali pamwambawa.

Popanga zida zamakina, ndikofunikira kusankha kuchuluka kwa roughness kutengera kulekerera kwa dimensional. Mitundu yosiyanasiyana yamakina imafunikira ma tebulo osiyanasiyana kuti asankhe.

Ndizofunikira kudziwa kuti tebulo limagwiritsa ntchito mtengo woyamba wa Ra, pomwe mtundu wakale wadziko umagwiritsa ntchito mtundu wachiwiri wamtengo wapatali wa Ra. Pa kutembenuka, pakhoza kukhala nkhani zapamwamba ndi zotsika. Timagwiritsa ntchito mtengo wapamwamba patebulo chifukwa umathandizira kukonza zinthu zabwino, ndipo mtengo wotsika umagwiritsidwa ntchito pazikhalidwe zapayekha.

Gome lolingana ndi kalasi ya kulolerana ndi kuuma kwapamtunda kwa muyezo wakale wadziko lili ndi zovuta komanso mawonekedwe. Pamlingo womwewo wololera, gawo la kukula, ndi kukula koyambira, makulidwe amtundu wa dzenje ndi shaft amasiyana, monganso momwe zimakhalira pamitundu yosiyanasiyana yokwanira. Izi ndichifukwa cha ubale pakati pa kulekerera kwa kulekerera kwakale ndi muyezo woyenera (GB159-59) ndi zinthu zomwe tazitchula pamwambapa. Pakali pano dziko latsopano muyezo kulolerana ndi zoyenera (GB1800-79) ali ndi muyezo kulolerana mtengo wa muyezo aliyense kukula mulingo wololera giredi ndi kukula gawo, kufewetsa lolingana tebulo kalasi kulolerana ndi roughness pamwamba ndi kupanga izo zambiri sayansi ndi wololera.

Pantchito yokonza, ndikofunikira kukhazikitsira chisankho chazovuta zapamtunda pazomwe zimatsimikizira kuwunika komaliza ndikuwunika bwino ntchito yapamtunda ndicnc kupanga ndondomekochuma cha zigawo za kusankha wololera. The kulolerana magiredi ndi pamwamba roughness mfundo zoperekedwa patebulo angagwiritsidwe ntchito monga kufotokoza kamangidwe.
