Porotakaro Roller Bearings

E rua nga huarahi reihi o roto me tetahi huarahi reihi porohita noa i roto i te whakakai o waho. No a ia he taonga whakaahuru-whaiaro. Na te koki koki e whakaae ana i roto i te awhe o te 1.5° ki te 3° he mea motuhake mo nga tono i roto i te henga i puta mai i nga hapa i roto i te whakapuru, te paheketanga o te rakau ranei.

Whakaahuatanga Hua

Ko te roera porotakaroa me te riihi riipene he papa whakapiri raina me te kaha kawenga nui, te nuinga e mau ana i nga kawenga radial. He iti te waku i waenga i te huānga hurihuri me te tapa pupuri o te mowhiti. He pai mo te hurihanga tere-tere.

I runga i te waahi, te kore ranei o te pupuri i nga taha i runga i te mowhiti, he rarangi rarangi kotahi penei i te NU, NJ, NUP, N, NF, me nga rarangi rarangi rua penei i te NNU me te NN.

He hanganga wehe tenei kawe me nga mowhiti o roto me waho.

Ka taea te whakamahi i te roera porotakaro me te kore he mata pupuri i runga i te mowhiti o roto, o waho ranei ka taea te whakamahi hei kawe mutunga kore utu na te nekehanga whanaunga o nga mowhiti o roto me waho i te ahunga axial. Ko te roera porotakaro e mau ana me te taha maui rua i tetahi taha o te mowhiti o roto, o waho ranei, me tetahi taha pupuri kotahi i tera taha o te mowhiti ka taea te tu ki tetahi tohu o te kawenga axial i tetahi huarahi.

He nui te rigidity ki nga kawenga radial te rarangi rua o nga peera porotakaro a ka whakamahia mo nga miro taputapu miihini.

I te nuinga o te waa, ka whakamahia nga kaakaa raima pereti rino me nga kaaahi miihini parahi ranei. Engari tera ano tetahi waahanga e whakamahi ana i nga whare herehere polyamide.

Kua hoahoatia nga peara me te hononga raina whakarereke i waenga i nga roera me nga huarahi reihi. Ko te riu o waho ranei ka mau tahi e te whare herehere ki te hanga i tetahi huihuinga ka taea te tango mai i etahi atu mowhiti me te mea he kotahi, kaore ranei he riu, he pai ki te whakauru me te whakaheke. ka whakamahia mo te tautoko axial floating.The bearing with axial rings and outer rings both having ribs can be used to carry a certain amount of axial loads and to limit axial displacement of either the shaft or the houses at one side or both sides.

Ko te rarangi takirua roera porotakaroa (momo NN3000k) me te taarua (1:12) he nui ake nga kawenga radial e mau ana i te kaha me te rigidity. I tua atu ka hangaia nga mea katoa i roto i te whakarōpūtanga tika e tika ana mo te miro tika.
