Kodi chotengera chosindikizidwa, mtundu wa chisindikizo chonyamula ndi chiyani?

 

Chotchedwa sealed bearing ndi cholimba kuti chikhale cholimba komanso cholimba, kotero kuti chigobacho chikhale cholimba bwino kuti chigobacho chikhale chosalala komanso malo abwino ogwirira ntchito, chigwire ntchito mokwanira, chikhale chotalikitsa moyo wa chigobacho, komanso chikhale ndi chigoba choyenera kuti chigobacho chisatuluke komanso kuti fumbi, nthunzi ya madzi kapena dothi lina lisalowe. Izi zimathandiza kuti chigobacho chitetezedwe.

 

Mtundu wa Chisindikizo Chonyamula:

TKapangidwe ka chipangizo chosindikizira cha ma bere ogudubuza kagawika m'magulu monga zisindikizo zolumikizirana ndi zisindikizo zosalumikizirana.

 

Kutseka mabearing kosakhudzana ndi kukhudzana

 

Kutsekereza zinthu zosagwirizana ndi kukhudza ndi njira yotsekereza zinthu yomwe imapanga mpata wochepa pakati pa shaft ndi chivundikiro cha nyumba yotsekerera zinthu. Mtundu uwu wa kapangidwe kotsekerera zinthu sukhudza shaft, kotero palibe kukangana ndi kuwonongeka, ndipo ndi woyenera kuzungulira mwachangu. Kuti muwonjezere mphamvu yotsekerera zinthu, mpatawo ukhoza kudzazidwa ndi mafuta. Zisindikizo zosagwirizana ndi kukhudza zinthu zophatikiza ndi kukhudza zinthu zophatikiza ndi kukhudza zinthu zophatikiza ndi izi: chisindikizo cha mpata, chisindikizo cha m'mizere yamafuta, chisindikizo cha labyrinth, chisindikizo cha mafuta, ndi zina zotero.

 

1. Kutseka mipata

Chisindikizo cha mpata chimasiya mpata waung'ono pakati pa shaft ndi chivundikiro cha bearing kudzera m'bowo, mpata wa radius ndi 0.1-0.3mm, mpata ukakhala wocheperako komanso wocheperako, kutseka kumakhala bwino.

 

2. Kutseka kwa groove yamafuta

 

Chisindikizo cha mafuta chimakonzedwa ndi cholumikizira cha mafuta cha annular chomwe chili mkati mwa chivundikiro cha kumapeto kwa chisindikizo cha bearing seal, ndipo cholumikizira cha mafuta chimagawidwa mozungulira, ndipo mafuta aliwonse a annular amalumikizana kudzera mu cholumikizira cha mafuta ndikulumikizana ndi thanki yamafuta, ndipo chiwerengero cha cholumikizira cha mafuta cha annular ndi cholumikizira cha mafuta chimatsimikiziridwa ndi kukula kwa chivundikiro cha kumapeto kwa chisindikizo.

 

3. Kutseka kwa Labyrinth

Mfundo yaikulu ya kutseka kumeneku ndikupanga njira yoyendera pa chisindikizocho ndi kukana kwakukulu kwa kuyenda kwa madzi. Mwa kapangidwe kake, pali mpata wochepa wozungulira pakati pa gawo losasunthika ndi gawo lozungulira kuti apange "labyrinth".

 

4. Kutseka chotchingira mafuta

 

Zisindikizo zolumikizirana za mabearing

Kutseka kolumikizana ndi njira yotsekera yogwiritsira ntchito shaft yolumikizira kumapeto kapena milomo ya mphira wopangidwa ndi vulcanized pa chigoba chachitsulo, ndipo magwiridwe ake otsekera ndi abwino kuposa kutseka kosakhudzana ndi kukhudzana, koma kukangana ndi kwakukulu, ndipo kutentha kumakwera kwambiri. Malo olumikizirana a shaft ndi chigoba amafunika kupakidwa mafuta, nthawi zambiri ndi mafuta ofanana ndi bearing. Zigoba zolumikizirana zimaphatikizapo makamaka: kutseka mphete ya felt, kutseka mbale yachikopa, kutseka mphete yolumikizira, kutseka mafupa, kutseka mphete yolumikizira, ndi zina zotero.

 

1. Kutseka mphete ya felt

Mzere wa trapezoidal umatsegulidwa pa chivundikiro cha bearing, ndipo chofewa cha gawo la rectangle chimayikidwa mu mzere wa trapezoidal kuti chigwirizane ndi shaft, kapena gland imakanikizidwa mozungulira kuti mphete ya felt ikanikizidwe ndikupanga kupanikizika kwa radial kuti igwire pa shaft, kuti ikwaniritse cholinga chotseka.

 

2.Mbale yachikopa yatsekedwa

 

Mbale yotsekedwa yachikopa (yopangidwa ndi zinthu monga rabara yokokedwa ndi mafuta) imayikidwa mu chivundikiro cha bearing ndikukanikizidwa mwachindunji ku shaft. Pofuna kulimbitsa mphamvu yotseka, kasupe wozungulira amakanikizidwa pa mphete yamkati ya chikopa, kotero kuti mphete yamkati ya chikopa ikhale yolimba kwambiri ndi shaft..

 

3. Mphete yotsekera yatsekedwa

Zisindikizo nthawi zambiri zimapangidwa ndi chikopa, pulasitiki kapena rabala yosagwira mafuta ndipo zimatha kupangidwa m'ma profiles osiyanasiyana ngati pakufunika. Mphete yotsekera yooneka ngati 0 ili ndi mawonekedwe ozungulira, kudalira mphamvu yake yotanuka kuti ikanikizire pa shaft, yokhala ndi kapangidwe kosavuta komanso kusakanikirana kosavuta. Zisindikizo zooneka ngati J ndi U zimagwiritsidwanso ntchito kwambiri, zonse ziwiri zimakhala ndi mawonekedwe ngati milomo.

 

4. Kutseka mafupa

 

Pofuna kulimbitsa mphamvu yonse ya chisindikizo cha mbale yachikopa, chitsulo chokhala ndi gawo lozungulira looneka ngati L komanso mawonekedwe a annular chimayikidwa mu rabara yosagonja mafuta, kotero kuti chisindikizo cha mbale yachikopa sichimavuta kuchisintha, ndipo moyo wake umakwera. Pankhani ya <7m/s, mabokosi ambiri onyamula mapampu a centrifugal pakadali pano ali otsekedwa ndi mafupa.

 

5. Kutseka mphete yotsekera

Ichi ndi mtundu wa chisindikizo cha annular chokhala ndi notch, chimayikidwa mu groove ya sleeve, sleeve imazungulira limodzi ndi shaft, ndipo mphete yotsekera imakanidwa pakhoma lamkati la gawo losasunthika ndi kusinthasintha komwe notch imakanidwa, ndipo imatha kusewera gawo lotsekera, ndipo kutseka kwamtunduwu kumakhala kovuta kwambiri.

 

Kusankha kapangidwe ka chisindikizo chonyamula

 

Posankha kapangidwe ka chisindikizo cha bearing, zinthu zazikulu zomwe muyenera kuganizira ndi izi: mafuta, kaya ndi mafuta kapena mafuta; Liwiro la mzere wa zigawo zotsekera; cholakwika cha kukhazikitsa kwa shaft; Kukula ndi mtengo wa malo okhazikitsira, ndi zina zotero.
