Abakhiqizi nabahlinzeki be-roller bearings e-China 30202 e-Tapered, umugqa owodwa

30202 Ama-roller bearings athambile, umugqa owodwa Isithombe Esivelele

Ama-roller bearings angu-30202 athambile, umugqa owodwa

Incazelo emfushane:

Ama-roller bearings aqoshwe ngomugqa owodwa aklanyelwe ukwamukela imithwalo ehlanganisiwe, esebenza ngesikhathi esisodwa njenge-radial kanye ne-axial loads. Imigqa yokukhomba yemigwaqo yomjaho ihlangana endaweni efanayo ku-bearing axis ukuze inikeze isenzo sangempela sokugoqa futhi ngenxa yalokho izikhathi zokungqubuzana eziphansi ngesikhathi sokusebenza. Umthamo wokuthwala umthwalo we-axial wama-roller bearings aqoshwe ngokwandisa i-contact angle α. Usayizi we-contact angle, ovame ukuba phakathi kuka-10° no-30°.

Izici zama-Tapered roller bearings

1. Ukungqubuzana okuphansi
Umklamo we-roller end olungiselelwe kahle kanye nokuphela kobuso ku-flange kukhuthaza ukwakheka kwefilimu yokuthambisa, okuholela ekungqubuzaneni okuphansi. Lokhu kunciphisa nokushisa kokungqubuzana kanye nokuguguleka kwe-flange.

2. Ukuthembeka kokusebenza okuthuthukisiwe
Ukuphela kobuso okulungiselelwe ezindaweni zokuthintana zama-roller kanye nemigwaqo yomjaho kusekela ukwakheka kwefilimu yokugcoba ye-hydrodynamic.

3. Ukuvumelana kwamaphrofayili namasayizi e-roller
Ukubekezelelana kobukhulu kanye nokwejiyometri kwama-roller bearings athambile kufana kakhulu. Lokhu kunikeza ukusatshalaliswa komthwalo okuhle kakhulu, kunciphisa umsindo nokudlidliza, futhi kwenza ukulayisha kusengaphambili kusethwe ngokunembe kakhudlwana.

4. Isicelo sokuthwala esiqinile
I-roller bearing enomugqa owodwa ivame ukulungiswa ngokumelene ne-roller bearing yesibili enomugqa owodwa. Ngokusebenzisa i-preload, ukusetshenziswa kwe-roller eqinile kungafinyelelwa.

5. Okungahlukaniswa
Indandatho yangaphakathi ene-roller kanye ne-cage assembly (ikhoni) ingafakwa ngokwehlukana nendandatho yangaphandle (indebe).
