He Tātaritanga Katoa o ngā Tauira Whero Ngira

Ngā peera roera ngirae whakamahia whānuitia ana i roto i te hoahoa miihini me te tiaki taputapu nā te mea he nui te kaha kawenga me te hoahoa kiato. Heoi, he maha tonu ngā tohunga hangarau me ngā miihini hokohoko e pōhēhē ana i ngā ingoa tauira maha, tae atu ki a NATR, NAKD, me KR. Ko tēnei tuhinga, i runga i te paerewa ā-motu GB/T 272, "Rolling Bearing Designation Method," e whakarato ana i tētahi tātaritanga hohonu o te arorau tohu roera ngira, e āwhina ana i ngā kaimahi ki te tere mōhio ki ngā tikanga whiriwhiri.

 

1. Te Wetewete i te Tohu Matua: Te Tikanga o ngā Kupumatua me ngā Tauira Taketake

 

Whēra roera ngiraKāore ngā tauira e tohaina matapōkeretia; e whai ana rātou i ngā ture waehere tino pakari. Ko te tohu matua he "tohu taketake" ā, muri iho ka whai i te whakamutunga, me te tohu taketake e whakaatu ana i te momo peera me ngā āhuatanga hanganga.

 

raupapa NA: e tohu ana i ngā peera roera ngira kāore he mowhiti o roto. Ka whakamahia e ēnei peera te pukapuka rakau hei ara rere mō te mowhiti o roto, ka penapena wāhi, ā, he pai hoki mō ngā tono me ngā mata rakau kua whakapakeketia.

 

Raupapa NK: he hanganga pumau ake ngā peera roera ngira me te mowhiti o roto, ā, he pai mō ngā tere teitei ake, ina kore rānei e tika te rauemi o te kakau mō te whakahaere tika i te ara reihi.

 

Raupapa KR: E tohu ana i ngā peera roera ngira me ngā toki kua whakapurua. He mea whakamahi noa ēnei i roto i ngā taputapu kawe me ngā pūnaha ara ārahi, he ngāwari te tāutanga me te kaha kawenga teitei.

 

NATR / NATV:He peera roera ngira ēnei me te mowhiti o waho he porowhita, kāore he mowhiti o roto. Ko te TR e tohu ana i te mowhiti o waho he porowhita me te hoahoa kimi pana, ko te V ia e tohu ana i te huinga katoa o ngā roera ngira (kāore he whare herehere). He pai mō ngā tere iti me ngā kawenga taumaha.

 

Tohutohu: Ko te wehewehe mēnā he mowhiti o roto kei te peera te taahiraa tuatahi ki te whiriwhiri i te peera. Ko ngā momo kāore he mowhiti o roto he iti ake ngā utu me ngā rahi radial iti ake, engari me nui ake te pakeke o te pou me te kounga o te mata.

 

II. Waehere Whakamutunga: Momo Hiri, Kerei, me te Momo Mowhiti o Waho

 

E whakamārama ana te reta whakamutunga i ngā āhuatanga mahi o te peera, ā, e pā tika ana ki te taiao mahi me te roa o te ora.

 

Te Whakamahinga Tikanga o te Whakamutunga

 

-2RS Hiri rapa taha-rua: Ātete ki te puehu me te wai, he pai mō ngā taiao makuku, puehu rānei.

 

-Z Taupoki puehu pereti maitai taha-kotahi: Ka tiaki i ngā matūriki nunui, ā, he pai ake te tere o te mahi ki te whakataurite ki ngā tauira hiri.

 

X Mowhiti o waho porotaka (kāore i te āhua-kame): He pai mō ngā tono e hiahia ana kia tino tika te tūnga.

 

Whare herehere TV Polyamide: Ka whakaiti i te taumaha, ka whakanui hoki i te tere mōrahi.

 

Hei tauira, ko te NA4904-2RS e tohu ana i tētahi whāriki roera ngira 20mm te whānui o roto, kāore he mowhiti o roto, he hiri rapa taha-rua. He pai mō ngā motuka iti, mō ngā pouaka miihini rānei.

 

3. Me pēhea te tere o te whakataurite i ngā tauira? Tikanga Kōwhiringa e Toru ngā Hipanga

 

Whakatauhia ngā whakaritenga hanganga: Me whai flange hei whakanoho? Ka whakaaetia te pou hei ara rere?

 

Tirohia te ripanga ine: Tīpakohia he tauira taketake i runga i te wāhi tāutanga (diameter o roto, diameter o waho, me te whānui).

 

Tāpirihia ngā kupu tāpiri i runga i ngā āhuatanga whakahaere: Whakaarohia ngā āhuatanga pēnei i te hiri, te whakahinuhinu, me te tere hei whiriwhiri i te momo e tika ana.

 

E taunakihia ana kia whakatauritehia te hoahoa hanganga whakawhiti-wāhanga i roto i te pukapuka hua me te ripanga tawhā ā-ahu kia mārama ai ki te hanganga ā-roto me te tikanga tāutanga.

 

Te whakahaere i te pūnaha tohu mōngā peera roera ngiraehara i te mea ko te whakaatu i te pūkenga hangarau anake engari he mea nui hoki mō te whakarei ake i te tohungatanga ratonga. Mā te mārama ki te ariā hangarau i muri i ngā tohu pēnei i te NA, KR, me te -2RS ka taea te whakapai ake i te kōwhiringa, te hoko, me te rapurongoā.
