Mitundu Yaikulu ndi Makhalidwe a Zigawo Zogwira Ntchito Zozungulira mu Malangizo Olunjika

Kuyerekeza kwa Magwiridwe Oyambira a Zitatu Zomwe Zimagwiritsidwa Ntchito KawirikawiriMalangizo Oyendetsera MizereLiwiro logwira ntchito la ma rolling linear guides lafika pa 300 m/min. Ku Europe ndi America, zida zopitilira ziwiri mwa zitatu za makina a CNC othamanga kwambiri zimagwiritsa ntchito ma rolling linear guides, omwe amagwiritsidwa ntchito kwambiri mu zida zamakono zosiyanasiyana zamakanika. Zigawo zogwirira ntchito zozungulira zonse zimagwiritsa ntchito mipira kapena ma roller ngati zinthu zozungulira. Zigawo zogwirira ntchito zozungulira zomwe zimagwiritsidwa ntchito kwambiri ndi izi:

 

1. Rolling Linear Guide Pair

 

Makhalidwe: Zinthu zozungulira zimalumikizana ndi groove yozungulira, zomwe zimapangitsa kuti zikhale ndi mphamvu zambiri zonyamula katundu, kulimba bwino, komanso kusinthasintha kochepa (nthawi zambiri 0.002 ~ 0.005, 5% ~ 2% yokha ya ma sliding guide pairs), mphamvu yosunga ndalama komanso zimatha kupirira katundu mbali zinayi (mmwamba, pansi, kumanzere, ndi kumanja). Kusiyana pakati pa kugwedezeka kwamphamvu ndi kosasinthasintha ndi kochepa kwambiri.

 

Kusawonongeka kwambiri, nthawi yayitali yogwira ntchito, komanso kuyika kosavuta, kukonza, ndi kudzola. Imalola kuthamanga kwa kayendedwe kopitilira kakhumi kuposa malangizo otsetsereka, zomwe zimapangitsa kuti kayendedwe kake kakhale kosinthasintha komanso kopanda kugwedezeka. Pakudyetsa pang'ono, imatha kuwongolera bwino malo ndi miyeso popanda kutsetsereka, ndipo imatha kukwaniritsa kudyetsa kolondola kwambiri kwa micron. 2. Rolling Linear Guide Sleeve Pair

Zinthu Zake: Kukangana kochepa, 0.001 ~ 0.004 yokha, mphamvu yopulumutsa. Kusuntha kosinthasintha komanso kolondola, sikukwawa pa liwiro lotsika.

 

Kulondola kwambiri, kukwawa kwa nthawi yayitali, komanso liwiro loyenda mwachangu. Kutha kudzisintha, kuchepetsa kulondola kwa makina azinthu zokhudzana nazo. Kusamalira mosavuta komanso mafuta.

 

Chingwe chowongolera ndi chowongolera ndi chozungulira, zomwe zimapangitsa kuti mtengo wake ukhale wotsika. Komabe, zinthu zozungulira zimakhala ndi malo olumikizirana ndi shaft, zomwe zimapangitsa kuti zikhale zochepa kunyamula katundu. Zoyenera kugwiritsidwa ntchito zomwe zimafuna kulondola kwambiri komanso kupepuka.

 

3. Rolling Spline Pair

Mawonekedwe: Kukana kukangana kochepa kwambiri, ndi coefficient of friction pakati pa 0.002 ndi 0.003, zomwe zimathandiza kuti pakhale kuzungulira kwa liwiro lalikulu kapena kuyenda kobwerezabwereza kolunjika (kuthamanga mpaka 100m/min ndi kupitirira apo). Kukana kukangana sikudalira liwiro; palibe kukwawa komwe kumachitika panthawi yoyenda pang'onopang'ono kobwerezabwereza.

 

Kuyika zinthu musanayambe kungathe kugwiritsidwa ntchito posintha kukula kwa mipira yozungulira kuti muchepetse kugwedezeka kumbuyo panthawi yozungulira kutsogolo ndi kumbuyo, potero kuchepetsa kugwedezeka ndikuwongolera kulimba ndi kulondola kwa kuyenda. Imakhala ndi mphamvu zambiri zonyamula katundu, nthawi yayitali yogwira ntchito, komanso kusunga bwino kulondola.

 

4. Mabuloko Otsogolera Ozungulira

Zinthu Zozungulira: Zinthu zozungulira ndi ma cylindrical rollers, okhala ndi mphamvu yonyamula katundu pafupifupi nthawi 10 kuposa ma ball bearingers. Mgwirizano wa friction coefficient ndi wochepa, pakati pa 0.005 ndi 0.01, ndipo kusiyana pakati pa dynamic ndi static friction coefficients ndi kochepa. Pa makina omwe amayamba, kuyimitsa, ndi kutembenuka pafupipafupi pama frequency apamwamba, amatha kuchepetsa kulemera konse kwa makina ndi kugwiritsa ntchito mphamvu, ndikuchotsa kutsetsereka. Amakwaniritsa kuyenda kosalala pansi pa mikhalidwe yolemera kapena yosinthasintha ya katundu.

 

Kuzindikira kwambiri, kuwongolera kolondola panthawi yokonza bwino mwachangu, osagwedezeka, magwiridwe antchito abwino owongolera panthawi yozungulira, kukonza kulondola kwa kutsatira makina ndi malo. Dongosolo lopaka mafuta ndi losavuta, ndipo kukhazikitsa, kusokoneza, ndi kusintha ndizosavuta. Sikungoyang'ana kutalika kwa bedi la makina, mabuloko angapo owongolera amatha kusankhidwa malinga ndi mphamvu yonyamula. Amagwiritsidwa ntchito kwambiri mu njira zoyendera zolunjika za zida za makina a NC ndi CNC.
