Chidutswa chokhazikika ndi gawo lokhala ngati mphete la nsonga yopindika yokhala ndi njira imodzi kapena zingapo.Mapiritsi osasunthika amagwiritsa ntchito ma radial omwe amatha kupirira katundu wophatikizika (radial ndi longitudinal).Ma bere awa akuphatikizapo: mayendedwe a mpira wakuya, mizere iwiri kapena mizere iwiri yolumikizana ndi mizere yolumikizana, mayendedwe odziyendetsa okha, zozungulira zozungulira, zofananira zodzigudubuza zofananira, mayendedwe a NUP cylindrical roller kapena omwe ali ndi mphete za HJ angular NJ mtundu wa cylindrical roller bearings. .

Kuphatikiza apo: makonzedwe onyamula pamapeto okhazikika angaphatikizepo kuphatikiza kwa mayendedwe awiri:

1. Mapiritsi a radial omwe amatha kunyamula katundu wozungulira, monga ma cylindrical roller bearings okhala ndi mphete imodzi popanda nthiti.

2. Perekani ma axial positioning bearings, monga mayendedwe a mpira wakuya, zitsulo zinayi zolumikizana ndi mpira kapena njira ziwiri.

Ma bearings omwe amagwiritsidwa ntchito poyika axial sayenera kugwiritsidwa ntchito poyika ma radial, ndipo nthawi zambiri amakhala ndi chilolezo chaching'ono akayika pampando wonyamula.

Pali njira ziwiri zosinthira kusuntha kotentha kwa matope onyamula shaft.Choyamba, gwiritsani ntchito chonyamulira chomwe chimangonyamula katundu wa radial ndipo chimatha kulola kusamuka kwa axial kuti kuchitike mkati mwazonyamula.Ma bere awa akuphatikizapo CARE toroidal roller bearings, singano roller bearings ndi cylindrical roller yonyamula popanda nthiti pa mphete.Njira ina ndiyo kugwiritsira ntchito mayendedwe a radial ndi chilolezo chochepa cha radial pamene chimayikidwa pa mpando wonyamula kuti mphete yakunja ikhale yoyenda momasuka mu njira ya axial.

Position njira yokhazikika yonyamula

1. Njira yotseka mtedza:

Mukayika mphete yamkati yokhala ndi kusokoneza koyenera, nthawi zambiri mbali imodzi ya mphete yamkati imatsutsana ndi phewa pa shaft, ndipo mbali inayo nthawi zambiri imayikidwa ndi lock nut (KMT kapena KMT A series).Zimbalangondo zokhala ndi mabowo opindika zimayikidwa mwachindunji papepala lojambulidwa, lomwe nthawi zambiri limakhazikika pamtengowo ndi nati wa loko.

2. Njira yoyikira Spacer:

Ndizosavuta kugwiritsa ntchito ma spacers kapena ma spacers pakati pa mphete zonyamula kapena pakati pa mphete zokhala ndi mbali zoyandikana: m'malo mwa mapewa ophatikizika kapena mapewa okhala ndi mpando.Muzochitika izi, kulolerana kwa dimensional ndi mawonekedwe kumagwiranso ntchito pazigawo zofananira.

3. Kuyika kwa manja opondapo shaft:

Njira inanso yonyamulira ma axial positioning ndiyo kugwiritsa ntchito ma stepped bushings.Ma bushings awa ndi oyenerera makamaka pokonzekera bwino.Poyerekeza ndi mtedza wa loko wa ulusi, amakhala ndi kuthamanga pang'ono ndipo amapereka kulondola kwambiri.Zitsamba zopondaponda nthawi zambiri zimagwiritsidwa ntchito ngati zopota zothamanga kwambiri, zomwe zida zotsekera zachikhalidwe sizingapereke kulondola kokwanira.

4. Njira yokhazikitsira kapu yokhazikika:

Mukayika mphete yakunja yokhala ndi kusokoneza koyenera, nthawi zambiri mbali imodzi ya mphete yakunja imatsutsana ndi phewa pampando wonyamula katundu, ndipo mbali inayo imayikidwa ndi chivundikiro chokhazikika.Chophimba chokhazikika chakumapeto ndi zomangira zake zomangira zimakhala ndi zotsatira zoipa pa mawonekedwe ndi machitidwe a kubereka nthawi zina.Ngati makulidwe a khoma pakati pa mpando wonyamula ndi bowo ndi wocheperako, kapena zomangika mwamphamvu kwambiri, msewu wakunja wa mphete ukhoza kukhala wopunduka.Mitundu yopepuka ya ISO 19 yopepuka imakhala pachiwopsezo chamtunduwu kuposa mndandanda wa 10 kapena wolemera kwambiri.

Kuyika masitepe a zokhazikika zokhazikika

1. Musanakhazikitse chifaniziro pa shaft, choyamba muyenera kutenga chithunzi cha pini yokonzekera yomwe imakonza jekete yonyamula, ndipo nthawi yomweyo pukutani pamwamba pa pepalalo bwino ndi loyera, ndikuyika mafuta ku magazini kuti muteteze dzimbiri. ndi mafuta (lolani kuti chotengeracho chizizungulira pang'ono pa shaft) .

2. Pakani mafuta opaka pampando wokwererapo ndi potengerapo: Ikani chodzigudubuza chokhala ndi mizere iwiri pampando wonyamulira, kenaka ikani chonyamulira chosokonekera ndi mpando wonyamula pa shaft palimodzi, ndikukankhira pakufunika. udindo kwa unsembe.

3. Musamangirire ma bolts omwe amakonza mpando wonyamula katundu, ndipo pangani nyumba zokhala ndi kuzungulira pampando wonyamula.Komanso ikani zonyamula ndi mpando kumbali ina ya shaft yomweyi, tembenuzani shaftyo kangapo, ndikulola kuti chonyamula chokhazikika chipeze malo ake.Kenako limbitsani mabawuti okhala ndi mipando.

4. Ikani manja a eccentric.Choyamba ikani manja a eccentric pamtunda wamkati wamkati wa chonyamuliracho, ndikumangitsani ndi dzanja mozungulira tsinde, ndiyeno ikani ndodo yaying'ono yachitsulo mkati kapena kutsutsana ndi cholumikizira pamanja.Menyani ndodo yaying'ono yachitsulo pozungulira tsinde.Ndodo zachitsulo kuti zikhazikike molimba manja, ndiyeno kumangitsa zomangira zomangira za hexagon pa dzanja la eccentric.

Zomwe zimakhudza kubereka

1. Pa nthawi yomweyi ya mapangidwe apangidwe ndi apamwamba, padzakhala moyo wautali wobala.Kupanga zonyamula kumadutsa njira zingapo zopangira, kutenthetsa, kutembenuza, kugaya ndi kusonkhanitsa.Kulingalira, kupita patsogolo ndi kukhazikika kwa chithandizo kudzakhudzanso moyo wautumiki wa kubereka.Chithandizo cha kutentha kwa chiberekero ndi njira yopera imakhudzidwa, ndipo khalidwe la mankhwala nthawi zambiri limagwirizana kwambiri ndi kulephera kwa kubereka.M'zaka zaposachedwa, kafukufuku wokhudzana ndi kuwonongeka kwa chigawo chonyamula pamwamba chawonetsa kuti njira yopera ikugwirizana kwambiri ndi khalidwe lapamwamba.

2. Chikoka chazitsulo zazitsulo zazitsulo ndizofunika kwambiri pakulephera koyambirira kwa kugubuduza.Ndi kupita patsogolo kwa ukadaulo wazitsulo (monga kunyamula zitsulo, vacuum degassing, etc.), mtundu wa zida zopangira zidasinthidwa.Kuchuluka kwa zinthu zopangira zinthu zomwe zimakhudzidwa pakuwunika kulephera kwatsika kwambiri, komabe ndi chimodzi mwazinthu zazikulu zomwe zimalepheretsa kulephera.Kaya kusankha kuli koyenera akadali kusanthula kulephera komwe kuyenera kuganiziridwa.

3. Pambuyo poyikidwa, kuti muwone ngati kukhazikitsa kuli kolondola, m'pofunika kuchita cheke choyendetsa.Makina ang'onoang'ono amatha kuzunguliridwa ndi manja kuti atsimikizire ngati akuzungulira bwino.Zinthu zowunikira zimaphatikizira kugwira ntchito molakwika chifukwa cha zinthu zakunja, zipsera, zopindika, torque yosakhazikika chifukwa chosakhazikika komanso kusakonza bwino kwa mpando wokwera, torque yochulukirapo chifukwa cha chilolezo chochepa kwambiri, cholakwika choyika, ndi kukangana kwa chisindikizo, etc. Dikirani.Ngati palibe cholakwika, imatha kusunthidwa kuti iyambitse ntchito yamagetsi.

Ngati kubereka kuli ndi vuto lalikulu chifukwa cha zifukwa zina, kunyamula kuyenera kuchotsedwa kuti mudziwe chifukwa cha kutentha;ngati chonyamuliracho chatenthedwa ndi phokoso, mwina chivundikirocho chikugwedeza tsinde kapena mafutawo auma.Kuonjezera apo, mphete yakunja ya bere imatha kugwedezeka ndi dzanja kuti ikhale yozungulira.Ngati palibe zotayirira ndipo kuzungulira kuli kosalala, kunyamula ndikwabwino;ngati pali looseness kapena astringency panthawi yozungulira, zimasonyeza kuti kubereka kuli kolakwika.Panthawiyi, muyenera kusanthulanso ndikuwunika akauntiyo.Chifukwa chodziwira ngati kubereka kungagwiritsidwe ntchito.
