Bearings rolair le teip ceithir-sreath
Ro-ràdh
Gabhaidh giùlan rolair le teip ceithir-sreath ri luchdan aonaichte (radial agus aiseach) aig astaran ìosal gu meadhanach.Tha iad air an cleachdadh cha mhòr a-mhàin ann an tagraidhean rolla obrach leithid muilnean rollaidh.
Chaidh ceithir sreathan de ghiùlan rolair le teip a chleachdadh gu soirbheachail ann an rèiteachadh giùlain mhuilnean rollaidh air feadh an t-saoghail le astaran rollaidh aig astar ìosal gu meadhanach.Air sgàth an dealbhadh aige, faodaidh an giùlan seasamh ri luchdan radial a bharrachd air na luchdan aiseach a tha an làthair ann an leithid de thagraidhean, agus mar as trice chan eil feum air giùlan smeòrach a bharrachd ann an rèiteachadh giùlain.Tha seo a’ ciallachadh gum faod leabhar-latha an rolla a bhith an ìre mhath goirid, agus faodaidh na còmhdach air gach taobh den rolla a bhith den aon dhealbhadh.
Is e giùlan rolair le teip ceithir-sreath na bearings trast-thomhas rolair as cumanta.Tha comas giùlain mòr aig an structar seo agus faodaidh e luchdan radial agus aiseach a ghiùlan aig an aon àm stèidhichte air luchdan radial.Tha an comas luchdan radial aige timcheall air 2.5 gu 3.5 uair nas àirde na giùlan sreath singilte, agus faodaidh e seasamh ri luchdan radial mòra agus luchdan aiseach.
Feartan agus buannachdan
● Stàladh nas sìmplidhe air sgàth nas lugha de phàirtean
● Sgaoileadh luchdan nas fheàrr de rolairean ceithir-sreath, a’ leantainn gu caitheamh nas lugha agus beatha seirbheis nas fhaide
● Tha an suidheachadh axial air an iris rolla air a dhèanamh nas sìmplidhe air sgàth lùghdachadh fulangas leud an fhàinne a-staigh
● Tha na tomhasan co-ionann ris an fheadhainn aig giùlan rolair àbhaisteach ceithir-sreath le fàinneachan eadar-mheadhanach
Iarrtas
Bithear a ’cleachdadh giùlan rolair le teip ceithir sreathan ann an innealan trom leithid muilnean mòra fuar is teth ann an gnìomhachas innealan plastaig.
