Mabearings Ozungulira Olimba Kwambiri

Ma Roller

Ma rollers omwe ali mkati mwa ma WD cylindrical roller bearing ndi ofunikira kwambiri chifukwa cha ntchito yawo pakugawa katundu. Ngakhale kuti amawoneka "osalala", ma rollers awa amagwiritsa ntchito mawonekedwe omwe ali ndi mawonekedwe a logarithmic. Kudzera mu kulumikizana kwa mzere pakati pa ma rollers ndi raceway, mphamvu ya radial load ndi mphamvu ya impact load ya ma cylindrical roller bearing ndi olimba momwemo. Pazovuta zina, gulu la mainjiniya a WD limapereka chithandizo chapafupi ndi malingaliro a mapangidwe ena.

Kumapeto kwa pamwamba pa ma rollers ozungulira kumathandiza kuti filimu yamadzimadzi ikhale yolimba. Izi zimapangitsa kuti ma rollers aziyenda bwino komanso kuti ntchito yawo ikhale yolimba.

Mphete

Mphete zamkati ndi/kapena zakunja za mabearing a cylindrical roller zimatsogolera ma rollers ndi nthiti. Ma assemblies a mphete amatha kulekanitsidwa kuti zikhale zosavuta kuyika ndipo amakanikiza payekhapayekha pa shaft ndi m'nyumba.

"Mphete yopanda ribless" ya mabearing a cylindrical roller imayenda mozungulira ndipo imagwiritsidwa ntchito ngati free-end, kapena float bearing. Mabearing a cylindrical roller amaperekanso kuuma kwakukulu, kupsinjika kochepa, komanso moyo wautali poyerekeza ndi mabearing ena chifukwa cha momwe amagwirizira kusuntha kwa axial.

Mphete zolumikizira ndi mipata ndi zonse

Makhola

Mabeyala ozungulira a cylindrical amagwiritsa ntchito khola kapena amapangidwa ngati bere lowonjezera kuti azitha kunyamula katundu wambiri popanda liwiro. Makhola achitsulo, mkuwa, ndi polyamide ndi ofala, ndipo PEEK ndi PPS sizimapezeka kawirikawiri.

Ntchito zambiri, komanso kugwiritsa ntchito kutentha kwambiri, zimapindula kwambiri ndi khola lachitsulo. Ubwino wina wotsutsana ndi mankhwala ndi liwiro umapezedwa kuchokera ku khola la polyamide ngati kutentha kwa ntchito sikukwera pafupifupi madigiri 70 Celsius, kapena pafupifupi madigiri 160 fahrenheit.

Mitundu

Mabearing a cylindrical roller amapangidwa kukhala ma single, double, kapena multi-row configurations. Mitundu yosiyanasiyana ya mabearing imatchedwa NU, NJ, NP, NUP, N, NF ya mabearing a cylindrical a mzere umodzi ndi NNU, NN ya mabearing a cylindrical a mzere umodzi.

Mitundu ya ma WD cylindrical roller bearings imapangidwa ndi mitundu yosiyanasiyana ndipo nthawi zambiri imasonyeza kusiyana kwa kapangidwe ka mphete yamkati kapena mphete yakunja:

● Mabearings a WD okhala ndi mzere umodzi wa cylindrical roller - nthawi zambiri amakhala a NU, NJ, NUP ndi N.

● Mabearings a WD okhala ndi mizere iwiri ya cylindrical roller - mapangidwe a NNU ndi NN.

● Mabearings a WD single row full complement cylindrical roller - makamaka mapangidwe a NCF ndi NJG.

● Mabearings a WD awiri odzaza mzere wozungulira wozungulira - kapangidwe ka NNF.

Kapangidwe kodziwika kwambiri ndi chogwirira cha mzere umodzi chozungulira. Izi zimachitika chifukwa cha njira zosavuta zosonkhanitsira, kuyika, ndi kuchotsa choyika chifukwa cha kulekanitsidwa kwawo. Pamene kakonzedwe ka mzere umodzi katchuka, kakonzedwe ka mizere iwiri ndi yambiri kamapereka mphamvu yayikulu yonyamula ma radial komanso kulimba kwa ma radial.

Ma Cylindrical Roller Bearings amagawidwa m'magulu otsatirawa kutengera malo, kuchuluka, ndi mtundu wa nthiti zomwe zili mkati ndi/kapena kunja.

Ma NU, N, ndi NN nthawi zambiri amakhala ma berearies aulere (“opanda malire” kapena “oyandama”) ndipo amaikidwa pa shaft kutali ndi ma drive end. NJ ndi NF amapereka kukana kwa axial mbali imodzi pomwe NUP imapereka kukana kwa axial mbali zonse ziwiri, ingagwiritsidwe ntchito ngati ma fixed-end bearing, ndipo imayikidwa pafupi ndi drive.

Kusinthasintha

Maberiyani ozungulira a cylindrical ndi osinthasintha monga momwe maberiyani amakhalira. Zigawo zake zimatha kusinthidwa ndi maberiyani ena opanga omwe ali ndi kukula ndi chiwerengero chofanana.

Makonzedwe oikira akhoza kukonzedwa m'njira zosiyanasiyana ndikufanana ndi mphamvu yonyamula katundu malinga ndi m'lifupi mwake, m'mimba mwake wamkati, ndi m'mimba mwake wakunja.

Maberiyani ozungulira a cylindrical akhoza kukhala ndi mphete zomwe zimayenda momasuka mbali ya axial (ya maberiyani opanda nthiti za mphete) kuti zigwiritsidwe ntchito zomwe zimakumana ndi kutentha kwa shaft.

Zimapezeka ngakhale ndi zisindikizo kapena zopangidwa ndi kapangidwe kogawanika. Zisindikizo zimateteza maberiya anu ku zinthu zodetsa monga madzi, fumbi, ndi matope ndipo zimapangitsa kuti mafuta azisungidwa bwino. Maberiya ozungulira a cylindrical opangidwa ndi kugawanika amapereka njira yosavuta yosamalira ndikusintha zinthu zomwe zimakhala zovuta kuzipeza.

Timakhulupirira kulankhulana mwachangu komanso moyenera. Kuti mudziwe zambiri, musazengereze kutero:

1. Gwiritsani ntchito mawonekedwe athu a Live Chat kuti mucheze nafe pakali pano. Maloboti sali otseguka - ife tokha! Ingodinani chizindikiro cha macheza pansi kumanja kwa sikirini yanu.

2. Imbani kapena tumizani imelo gulu lathu lodziwa bwino ntchito yogulitsa zinthu, lomwe si la komishoni.

3. Titumizireni uthenga pogwiritsa ntchito fomu yathu yolumikizirana yachangu komanso yosavuta.

WD Bearing Group imapanga mitundu yonse ya mabearing a cylindrical roller, onse omwe ndi ofanana komanso osafanana. Mabearing a cylindrical roller opangidwa mwamakonda amapezeka kuti agwirizane ndi pulogalamu yanu komanso ndemanga ya pulogalamu yopanda chiopsezo komwe timapereka malangizo athu auinjiniya kuti tiwongolere pulogalamu yanu kapena kuchepetsa ndalama zomwe mumagwiritsa ntchito.
