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 akuberekaakhoza nthawi imodzi kupirira mphamvu ya axial ndi mphamvu yozungulira, pamene mpira njira yothandizirayi ndi yoyenera kwa zitsulo zazing'ono zowononga wononga kapena zida za makina otsekedwa bwino, chifukwa pogwiritsa ntchito dongosolo ili la makina oyika njira, kulondola kwake ndi kosadalirika kwambiri, makamaka chiŵerengero cha kutalika kwa mita imodzi ya zitsulo zazikulu zowononga (mpira wononga ndi wochepa thupi), mapindikidwe ake amawotcha 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, enanso amachitidwe othandizira
Mapeto amodzi amakhazikika ndipo mapeto ena amathandizidwa: kunyamula pamapeto okhazikika kungathenso kupirira mphamvu zonse za axial ndi ma radial, pamene mapeto ochiritsira amangolimbana ndi mphamvu zowonongeka ndipo amatha kuyandama pang'ono, 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 screw adakhazikika: Mwanjira iyi, kunyamula kumapeto kokhazikika kumatha kunyamula mphamvu ya axial nthawi yomweyo, ndipo kuyika koyenera kungagwiritsidwe ntchito pa screw kuti athandizire kuuma kwa wononga, komanso kupunduka kwa kutentha kwa screw kumathanso 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.
