Mpira konda, yomwe ili m'gulu lamagulu a zida zamakina, ndi chida chabwino kwambiri chonyamula makina chomwe chimatha kusinthira kusuntha kozungulira kukhalakusuntha kwa mzere.Ball screw imakhala ndi screw, nati, chipangizo chobwerera kumbuyo ndi mpira, ndipo ili ndi mawonekedwe olondola kwambiri, osinthika komanso ochita bwino kwambiri nthawi imodzi.
Pali njira zitatu zazikulu kukhazikitsa mpira wononga, kutanthauza, mbali imodzi yosasunthika, wina mapeto ufulu unsembe njira; malekezero amodzi atakhazikika, njira ina yothandizira unsembe; onse malekezero okhazikika unsembe njira.
1,Mapeto amodzi okhazikika, njira imodzi yaulere
Mapeto amodzi adakhazikika, enanso njira yokhazikitsira yaulere: mathero okhazikika akuberekaItha kupirira nthawi imodzi kupirira mphamvu ya axial ndi mphamvu yozungulira, pomwe mpirawo njira yothandizirayi ndiyoyenera kunyamula zinyalala zazing'ono zazing'ono kapena zida zamakina zotsekedwa kwathunthu, chifukwa mukamagwiritsa ntchito dongosolo ili la njira yoyikira makina, kulondola kwake ndikodalirika kwambiri, makamaka kwautali. -diameter chiŵerengero cha zitsulo zazikulu zowononga (mpira wononga ndi yowonda), kutentha kwake kumawonekera kwambiri. Komabe, kwa wononga 1.5m kutalika, kusiyanasiyana kwa 0.05 ~ 0.1mm pansi pazikhalidwe zosiyanasiyana za kuzizira ndi kutentha ndizabwinobwino. Komabe, chifukwa cha mawonekedwe ake osavuta komanso kukhazikitsa kosavuta ndi kutumiza, zida zambiri zamakina olondola kwambiri zikugwiritsabe ntchito dongosololi. Komabe, pali mfundo yomwe ikufunika chisamaliro chapadera ndi chakuti kugwiritsa ntchito kamangidwe kameneka kuyenera kuwonjezeredwa ku grating, pogwiritsa ntchito mphete yotsekedwa mokwanira kuti apereke ndemanga, kuti athe kuwononga bwino ntchito.
2, malekezero amodzi atakhazikika, mbali ina yothandizira
Mapeto amodzi ndi okhazikika ndipo mapeto ena amathandizidwa: kunyamula pamapeto okhazikika kungathenso kulimbana ndi mphamvu zonse za axial ndi radial, pamene mapeto othandizira amangolimbana ndi mphamvu zowonongeka ndipo amatha kuchita pang'ono kuyandama kwa axial, komanso kuchepetsa kapena kupewa. kupindika kwa screw chifukwa cha kulemera kwake. Kuphatikiza apo, matenthedwe amatenthedwe a wononga mpira wothandizira wononga ndi ufulu kutalikira kumapeto kumodzi. Choncho, iyi ndiyo njira yomwe imagwiritsidwa ntchito kwambiri. Mwachitsanzo, zoweta zazing'ono ndi sing'anga CNC lathes, ofukula Machining malo, etc. onse ntchito dongosolo.
3,Zokhazikika pamapeto onse awiri
Mapeto onse awiri a wononga amakhazikika: Mwanjira iyi, kunyamula kumapeto kokhazikika kumatha kunyamula mphamvu ya axial nthawi yomweyo, ndipo kuyika koyenera kungagwiritsidwe ntchito pa screw kuti athandizire kuuma kwa screw, ndi kutentha. mapindikidwe a wononga angathenso kulipidwa pang'ono. Chifukwa chake, zida zazikulu zamakina, zida zamakina olemera komanso makina otopetsa kwambiri komanso makina ophera amagwiritsidwa ntchito kwambiri pamapangidwe awa. Zoonadi, pali zofooka, ndiko kuti, kugwiritsa ntchito kamangidwe kameneka kumapangitsa kuti ntchito yokonzanso ikhale yovuta kwambiri; kuonjezera apo, ngati kuyika ndi kusintha kwa malekezero awiri a preload ndi yaikulu kwambiri, zidzatsogolera kugunda komaliza kwa wononga kuposa mapangidwe apangidwe, phula lidzakhalanso lalikulu kuposa phula lapangidwe; ndipo ngati malekezero awiri a natiwo sakukwanira, zitsogolera ku zotsatira zosiyana, zomwe zingayambitse kugwedezeka kwa makina, zomwe zimapangitsa kuchepetsedwa kulondola. Choncho, ngati dongosolo lakhazikika pa malekezero onse awiri, ndiye kuti disassembly iyenera kusinthidwa motsatira malangizo, kapena mothandizidwa ndi chida (wapawiri pafupipafupi laser interferometer) kuti asinthe, kuti asawononge zosafunika.
