Kukonza Mfundo ya screw expansion
Kukonza mfundo ya wononga zokulitsa: kukonza kwa wononga zokulitsa ndiko kugwiritsa ntchito mawonekedwe owoneka ngati V kulimbikitsa kukulitsa kuti apange kugundana ndi mphamvu yomangirira, kuti mukwaniritse kukonza.Mapeto amodzi a screw ndi ulusi ndipo mapeto ena ndi tapered.Mkate umakutidwa ndi chikopa chachitsulo, ndipo theka la silinda yachitsulo imakhala ndi mabala angapo.Ikani pamodzi mu dzenje lomwe linakhomeredwa pakhoma, ndiyeno tsekani mtedza.Mtedzawu umakoka wononga panja, ndikukokera digiri ya vertebral mu silinda yachitsulo, yomwe imakulitsidwa, kotero imakhazikika pakhoma.Nthawi zambiri amagwiritsidwa ntchito kulumikiza mpanda woteteza, chotchingira, chowongolera mpweya, etc. pa simenti, njerwa ndi zinthu zina.Komabe, kukonza kwake sikodalirika kwambiri, ndipo ngati katunduyo ali ndi kugwedezeka kwakukulu, akhoza kumasuka, choncho sikovomerezeka kukhazikitsa mafani a denga.Mfundo ya bawuti yokulirapo ndikuti bawuti yowonjezera ikagunda mu dzenje pansi kapena khoma, nati pa bawuti yowonjezera imalumikizidwa ndi wrench, ndipo bawutiyo imatuluka, koma manja akunja achitsulo samasuntha.Chifukwa chake, mutu waukulu pansi pa bawuti umakulitsa manja achitsulo kuti mudzaze dzenje lonselo, ndipo panthawiyi, bawuti yokulirapo siyingatulutsidwe.
Kukonzekera kwa zomangira za telescopic ndiko kugwiritsa ntchito mawonekedwe amitundu yosiyanasiyana, kuti alimbikitse kugundana kwa ma telescopic, kuti akwaniritse kukonza.Zomangira zake zimakhala ndi ulusi kumapeto kwake ndi thupi la vertebral kumbali inayo.Mbali yakunja imakutidwa ndi khungu lachitsulo, ndipo silinda yachitsulo imakhala ndi mabala angapo.Lumikizani mu dzenje lomwe linakhomeredwa pakhoma limodzi ndi limodzi, kenaka tsekani natiyo, yomwe imakokera wononga panja, imakokera wononga mu silinda, ndikukokera silinda pakhungu lachitsulo.Silinda yachitsulo imakulitsidwa ndikumamatira kukhoma, komwe nthawi zambiri amagwiritsidwa ntchito kukonza zinthu monga simenti ndi njerwa monga ma guardrail, ma awnings ndi ma air conditioners.Komabe, kukonza kwake sikodalirika kwambiri, ndipo kumatha kumasuka ngati kuli ndi nkhawa yayikulu komanso kugwedezeka, kotero sikuvomerezeka kuyika fan fan.Mfundo yake ndi yakuti bolt yowonjezera ikathamangitsidwa mu dzenje pansi kapena khoma, nati pa bawuti imamangirizidwa ndi wrench, ndipo bolt imasunthira kunja, koma dzenje lachitsulo kunja silisuntha.Choncho, mutu waukulu pansi pa bolt umakweza dzenje lachitsulo kuti mudzaze dzenje lonselo.Panthawiyi, bawuti yowonjezera siyingatulutsidwe.Maboti okulirapo amapangidwa ndi ma bolts owunikidwa, machubu okulitsa, mapadi athyathyathya, mapepala akasupe ndi mtedza wa hexagonal.M'makalasi opitilira 10, pali 3.6, 4.6 ndi 4.8, 5.6 ndi 6.8, 8.8, 9.8, 10.9 ndi 12.9 motsatana.Manambala asanafike komanso atatha ma decimals motsatana amawonetsa kulimba kwamphamvu komanso kuchuluka kwa zokolola za zida za bawuti.Mwachitsanzo, bawuti yowonjezera yokhala ndi magwiridwe antchito a 4.6 ili ndi matanthauzo otsatirawa: 1, mphamvu yodziwika bwino ya bawuti imafika kupitilira 400 MPa;2. Chiŵerengero cha zokolola za bawuti yowonjezera ndi 0.6;3. Mphamvu zokolola za bawuti yowonjezera ndi 400 × 0.6 = 240 MPa.
Chomangira chokulitsa chimapangidwa ndi wononga ndi chubu chokulitsa, mchira wa wononga ndi conical, ndipo mainchesi amkati a chulucho ndi okulirapo kuposa chubu chokulitsa.Natiyo ikamangika, wonongayo imasunthira kunja, ndipo gawo la conical limadutsa mumayendedwe axial a ulusi, motero amapanga kukakamiza kwakukulu kwakunja kozungulira kwa chitoliro chokulitsa.Kuonjezera apo, mbali ya cone ndi yaying'ono kwambiri, kotero kuti khoma, chitoliro chokulitsa ndi gawo la conical limapanga mikangano yodzitsekera, motero kukwaniritsa zotsatira zokhazikika.Pad kasupe pa screw yowonjezera ndi gawo lokhazikika.Chifukwa kutsegula kwake kumakhala kogwedezeka komanso zotanuka, amatchedwa washer wa masika.Ntchito ya makina ochapira masika ndi kuboola mtedza ndi pad lathyathyathya ndi ngodya zakuthwa za potsegula molakwika kuti mtedza usagwe.
