Kodi kusiyana pakati pa mabearing a cylindrical roller ndi mabearing a needle roller ndi kotani?

 

Mabeya ozungulira a cylindrical

Mabeya ozungulira a cylindricalNdi ya mabearing olondola, ndipo chitsogozo cha flange cha bearing yokonzedwa bwino chimapangidwa ndi khola, ma rollers ndi mphete ya shaft yotsogolera, yomwe imatha kulekanitsidwa ndi mphete ina yoberekera ndipo ndi ya bearing yolekanitsidwa. Mtundu uwu wa bearing ndi wosavuta kuyika ndikuchotsa, makamaka pamene mphete zamkati ndi zakunja, ma shaft ndi ma housings amafunika kuti zigwirizane.

 

Maberiya awa ali pamzere wolumikizana ndi mipikisano. Kulemera kwake ndi kwakukulu, ndipo makamaka amanyamula katundu wozungulira. Maberiya amodzi okha okhala ndi ma flanges m'mphete zamkati ndi zakunja ndi omwe amatha kunyamula katundu wocheperako wa axial kapena katundu waukulu wa axial; Poyerekeza ndi maberiya ena osonkhanitsa omwe ali ndi miyeso yofanana, mtundu uwu wa beriya uli ndi mawonekedwe a katundu wambiri, phokoso la pansi komanso liwiro lalikulu, ndipo kukangana pakati pa chinthu chozungulira ndi flange ya mphete ndi kochepa, ndipo ndikoyenera kuzungulira mwachangu. Ndikoyenera kugwiritsidwa ntchito ndi mitundu yonse ya makina olondola komanso makina opangira migodi. Komabe, ma shaft, zinthu zozungulira ndi zina zokhudzana nazo zomwe zimagwirizana ndi maberiya otere ziyenera kukonzedwa molondola.

 

Malinga ndi ngati mpheteyo ili ndi flange kapena ayi, ikhoza kugawidwa m'magulu a NU, NJ, NUP, N, NF ndi ma bearing ena a cylindrical roller okhala ndi mzere umodzi, ndi NNU, NN ndi ma bearing ena a cylindrical roller okhala ndi mizere iwiri. Bearing ndi kapangidwe kolekanitsidwa ndi mphete yamkati ndi mphete yakunja.

 

Mabeya ozungulira a cylindricalPopanda ma flanges m'mphete zamkati kapena zakunja, zitha kusunthidwa mozungulira ndipo zitha kugwiritsidwa ntchito ngati ma bearing-end free-end. Ma bearing a cylindrical roller okhala ndi ma flanges awiri mbali imodzi ya mphete zamkati ndi zakunja ndi flange imodzi mbali inayo ya ferrule amatha kupirira kuchuluka kwa katundu wa axial mbali imodzi. Nthawi zambiri, ma cage opondaponda mbale yachitsulo amagwiritsidwa ntchito, kapena ma cage olimba opindidwa ndi mkuwa. Komabe, ma cage ena amapangidwa pogwiritsa ntchito polyamide.

 

Mabeya ozungulira a singano otseguka okhala ndi chikho chokokedwa

 

Ma bereji ozungulira singano

Mabeya ozungulira a singano ndi mabeya ozungulira okhala ndi ma cylindrical roller, omwe ndi oonda komanso aatali poyerekeza ndi mainchesi awo. Mabeya otere amatchedwa ma needle roller. Ngakhale kuti ndi ang'onoang'ono, mabeyawo ali ndi mphamvu zambiri zonyamula katundu, ndipo mabeya ozungulira a singano ali ndi ma rollers oonda komanso aatali (ma diameter a roller D).≤5mm, L/D≥2.5, L ndiye kutalika kwa roller), kotero kapangidwe ka radial ndi kakang'ono, ndipo dayamita yawo yamkati ndi mphamvu yonyamula katundu ndizofanana ndi za mitundu ina ya ma bearing, ndi dayamita yaying'ono yakunja, yomwe ndi yoyenera makamaka nyumba zothandizira zomwe zili ndi miyeso yochepa yoyikira radial.

 

Chifukwa chake, mabearing a singano amagwiritsidwa ntchito makamaka nthawi zina, kotero amagwiritsidwa ntchito kwambiri m'magalimoto, njinga zamoto, ndi makina osokera nsalu. Ndipo mphete yamkati ya singano ndi yosankha, kunena mosapita m'mbali, ngati kuuma ndi kukhwima kwa shaft kukukwaniritsa zofunikira, simungathe kufanana ndi mphete yamkati (malo ndi ochepa), koma ngati digiri ya machining ya shaft ndi yotsika, kapena yofewa pang'ono, muyenera kufanana ndi mphete yamkati ngati msewu wothamanga.

 

Kusiyana pakati pamabearing a cylindrical roller ndi mabearing a singanondi motere:

 

1. Chinthu chozungulira cha chogwirira chozungulira ndi chozungulira chopapatiza; Zinthu zozungulira za chogwirira chozungulira cha singano ndi zozungulira zooneka ngati singano;

 

2. Kapangidwe ka ma bearing a cylindrical roller ndi kakakulu kuposa ka ma bearing a singano;

 

3. Kuwonjezera pa mphamvu ya radial, chozungulira chozungulira chimathanso kupirira mphamvu ya axial, pomwe chozungulira cha singano chimatha kupirira mphamvu ya radial yokha;

 

4. Maberani ozungulira a cylindrical amagawidwa m'mizere imodzi, mizere iwiri ndi mizere yambiri, yomwe imagwiritsidwa ntchito m'malo osiyanasiyana komanso nthawi zosiyanasiyana;

 

5. Liwiro logwira ntchito la mabearing a cylindrical roller ndi lalikulu kuposa la mabearing a singano roller;

 

6. Mabeyala ozungulira a cylindrical nthawi zambiri amapangidwa ndi chitsulo chapamwamba kwambiri komanso chitsulo chapadera; Mabeyala ozungulira a singano okhala ndi makoma owonda amasindikizidwa ndi mbale zachitsulo. 

 

Nthawi yogwiritsira ntchito

 

Pakupanga makina, kukula kwa shaft nthawi zambiri kumatsimikiziridwa kaye, kenako chogwirira chozungulira chimasankhidwa malinga ndi kukula kwa shaft. Komabe, pamene chogwiriracho chili chochepa mu diameter ya makina, ma bearing a singano, ma bearing a mpira kapena ma roller a kuwala kowonjezera ndi mndandanda wa ultra-light amasankhidwa; Pamene malo a axial a chogwiriracho mu makina ali ochepa, ma bearing a mpira kapena ma roller amapezeka ochepa kapena ochepa kwambiri.

 

Ma Radial needle roller ndi zigawo za khola, ma stamped outer ring needle roller bearing, ma solid ring needle roller bearing, ma thrust needle roller bearing amagwiritsidwa ntchito kwambiri mu transmission system, steering system, motorcycle engine connecting rod of manufacturers and construction machinery, ndi zina zotero, ndipo ndi oyenera zochitika zokhala ndi malo ochepa komanso mphamvu yayikulu yonyamula katundu. Ma Needle roller bearing ali ndi ma roller oonda komanso aatali (kutalika kwa roller ndi 3 ~ 10 nthawi ya m'mimba mwake, ndipo m'mimba mwake nthawi zambiri si woposa 5mm), kotero kapangidwe ka radial ndi kakang'ono, ndipo kukula kwake kwa m'mimba mwake ndi mphamvu yonyamula katundu ndizofanana ndi za mitundu ina ya ma bearing, ndipo m'mimba mwake wakunja ndi wocheperako, womwe ndi woyenera kwambiri pazotsatira zothandizira pomwe kukula kwa radial kulibe malire.
