E rua nga momomowhiti patuhe kino, ko tetahi ko te pakaru o te reihi, ko tetahi ko te niho whati.Neke atu i te 98% te kino o te huarahi reihi, no reira ko te kounga o te huarahi reihi tetahi take nui e pa ana ki te oranga o te iwi.mowhiti patu.I roto i era, ko te maro o te ara reihi, te hohonu o te paparanga, te radius curvature reihi me te koki whakapiri ko nga mea tino nui e wha e pa ana ki te kounga o te reihi.
1. Te pakeke o te ara whakataetae
Te tinei pakeke o temowhiti patuHe nui ake te awe o te riihi riihi ki runga i tana kawenga pateko kua tohua.Mena ko te 1 te kawenga pateko i te 55HRC, ko te hononga i waenga i te kawenga pateko kua whakatauhia o te pikaunga me te pakeke o te huarahi reihi e whai ake nei:
| Te pakeke o te ara whakataetae HRC | 60 | 59 | 58 | 57 | 56 | 55 | 53 | 50 |
| Whakatauhia te uta pateko | 1.53 | 1.39 | 1.29 | 1.16 | 1.05 | 1 | 0.82 | 0.58 |
Ko teslewing bearingmai XZWDslewing bearingKo te pakeke o te riihi o te kamupene he 55HRC~62HRC.
2.Te hōhonutanga o te paparanga maro o te ara reihi
Ko te hohonutanga e tika ana o te paparanga whakapakeke ko te taurangi e temowhiti patue kore e pakaru te riipene.Ina teslewing bearingka mau i te kawenga o waho, ka huri te poroi rino me te huarahi reihi mai i te whakapiri ira ki te whakapiri mata, a ko te mata whakapiri he mata porotiti.I tua atu i te ahotea compressive, kei raro ano te ara reihi ki te ahotea kutikuti, a ko te ahotea kutikuti teitei ka puta i te hohonutanga o te 0.47a (te tuaka-ahuru o te ellipse whakapiri) i raro i te mata, Koinei hoki te take i puta ai te kua tohua te hohonu o te paparanga i roto i te paerewa kia rite ki te diameter o te poro maitai hei utu mo te diameter o temowhiti patu, ka hoatu te uara whai mana iti i roto i te paerewa.Ko te kawenga pateko kua whakatauhia C o te kawe he rite ki te hohonu o te paparanga pakeke H0.908.Mena ka tineia te hohonu o te paparanga e tika ana kia 4mm ki te 2.5mm, ka whakahekehia te kawenga pateko C mai i te 1 ki te 0.65, ko te tupono ka pakaru teslewing bearingna te ngenge ka nui haere te tihorenga.
Hei tauira, ko teslewing bearingte hohonu o te papa reihi013.35.1250 te ara reihi he ≥ 3.5mm.
3.Te pūtoro piko o te ara reihi
Ko te radius curvature huarahi reihi e tohu ana ki te radius curvature o te huarahi reihi i te wahanga poutū.Ko te ōwehenga t o te pūtoro o te ara reihi ki te pūtoro o te pōro rino ka tino pa ki te kawenga pateko whakatau me te ora ngenge o temowhiti patu.Ina t=1.04, ko te kawenga pateko kua tohua me te oranga ngenge he 1, me te hononga e rite ana i waenga i te kawenga pateko kua tohua me te oranga ngenge o temowhiti patua ko t e penei ana.
| ōwehenga kōpiko | 1.04 | 1.06 | 1.08 | 1.10 |
| Whakatauhia te uta pateko | 1 | 0.82 | 0.72 | 0.65 |
| Te oranga ngenge | 1 | 0.59 | 0.43 | 0.33 |
Ka kitea mai i te ripanga i runga ake nei ko te nui ake o te radius ōwehenga, ko te iti iho o te kawenga pateko whakatau me te poto ake o te oranga o te ratonga.
4.Raceway koki whakapā
Ko te koki whakapiri e tohu ana ki te koki i waenga i te raina e hono ana i te waahi whakapiri o te poi rino i runga i te huarahi reihi me te pokapu o te poi rino me te waahanga radial (rererangi whakapae) o teslewing bearing.Ko te kawenga pateko C o temowhiti patuhe riterite ki te SINα, a ko te koki whakapiri taketake ko te tikanga 45°.Ina teslewing bearinghe āputa, he nui ake te koki whakapā tūturu i te koki whakapā taketake.Ko te nui ake o te aputa, ka nui ake te koki whakapiri.I roto i te awhe mokowhiti kua tohua e te paerewa, ka piki ake i te 2 ° ~ 10 °, ara, ko te koki whakapiri pono ka tae ki te 47 ° ~ 55 °, he huringa pai mo te kaha o te kawe.Engari ki te nui te koki whakapiri taketake me te mokowhiti, ka nui ake te koki whakapiri tuuturu ki te 60°.I te wa e mau ana te huarahi reihi, ka piki ake te mokowhiti, ka piki ake ano te koki whakapiri.I tenei wa, ka nui ake pea te ellipse whakapiri i te tapa o te ara reihi., Ko te tino kaha o te ara reihi ka nui ake i te ahotea i whakatauhia e te ariā, ka hinga te tapa o te ara reihi me teslewing bearingka taka.
Hei tauira, ko te koki whakapiri taketake o teslewing bearingKo te 013.40.1250 he 45°.
