I Runga I Te Whaa, E Maarama Ana Koe? ! (a)

Tono And Vwhakatuu Of Thread Gauge

 

(1) Te kaupapa o te whakamahi mehua (1) Ture whanui.

I te tirohanga o te miro ia ra, he maha tonu nga tautohetohe mo te whakamahi i nga mehua. Ara ko te mea, ka tirohia te miro me te mehua hou me te mehua tawhito, ka rereke pea nga whakatau tirotiro.

 

(2) Ko te paerewa e kii ana:

Ko te whakamahi i te mehua miro (mowhiti me te mehua pereki) hei tirotiro i te miro o te kaitono arumoni ko te tikanga ine anake ka taea te whakatau mena e whakaaehia ana te hua kaore ranei.

Ka whakamahia ana nga mehua miro me nga taputapu ine ki te tirotiro, kaua e herea tetahi kaikawe mena kei roto te rahi miro i nga rohe kua whakaritea. He whakatau ki te tirotiro i te tohu miro me te mehua miro.

 

(3) Mahi tirotirohia te mehua miro.

Ka whakamahia te haere ki te tirotiro i te rahi o te taha o te tinana (ara, te diameter ware hohe) o te miro.

(Taonga mowhiti LO) kaore ranei he mehua haere (mehua miihini HI) e whakamahia ana hei tirotiro i te diameter kotahi o te miro.

Tirohia me te mehua mowhiti maeneene me te mehua uwha maeneene ranei. Ka whakaaetia hoki kia tirohia te diameter nui o te miro o waho me te diameter iti o te miro o roto me te mehua tohu (micrometer, caliper ranei).

Tohu ingoa whakarōpū me te Tono.

(1) Te mehua mahi

Ko te mehua miro e whakamahia ana mo te hanga, hanga, me te tirotiro i te miro tere.

 

(2) Tae Whakaae

Ko te mehua miro e whakamahia ana e te tari tirotiro te kanohi ranei o te kaiwhakamahi ka whakaae ana ki te miro o te mowhiti.

 

(3) Tohu Whakaako

Ko te mehua miro e whakamahia ana e te tari tirotiro te kanohi ranei o te kaiwhakamahi ka whakaae ana ki te miro o te mowhiti. Tirohia mēnā he whaimana te waahanga miro mahi ki te mahi me te tirotiro.

Ko te tohu mo te mehua mowhiti miro ka whakatutukihia e te miro tirotiro i te mehua (whakawa kounga).

Ko te mehua miro miro me te miro e toru-ngira te tirotiro i te ngira he tohu (whakatau rahinga).

 

Nga whakaritenga mo te whakamahi i te mehua

 

(1) Ko te tuunga kātaketanga hoahoa o te mehua miro kei roto i te rahinga rohe o te miro hua. Kia pai ai te tautohetohe na te rereketanga o te uara rohe tuturu (nga kakahu hou me nga tawhito) o nga mehua hou me nga tawhito e whakamahia ana.

 

(2) I roto i te Paerewa Amerikana ANSI B1.2: 2007 me te paerewa ISO1502 o te ao, e kii ana hoki kia wehea te mehua miro taapiri kia rua nga momo mehua: Tae Mahi me te mehua whakaaetanga (me te mehua tauineine Amerika x pai me te rereketanga kino ).

 

(3) Te mehua mahi me te mehua whakaae.

Manatokona mo te mehua mowhiti miro

 

(1) E rua nga tikanga whakatika mo te aho mowhiti miro

He whakatau kounga ki te whakatika i te mehua mowhiti miro mahi me te miro tirohia te mehua piro.

He whakatau ine ki te whakamahi i te mehua roa, me te miihini miihini wangei, me ona taonga (penei i te matau inenga o roto, poari mehua, mowhiti whakamatau, me etahi atu).

 

(2) Nga tikanga me nga whakaritenga o te miro miro mehua whakatikatika

Ko nga mehua mowhiti miro katoa kia ma i waenga o nga miro, a kaore he hinu me nga poke e uru ki nga miro.

Ko nga mehua mowhiti miro katoa me nga miro e pai ana te ahua, a e kore e tukuna he taera kia he ranei.

Me mau ki te mehua haere ki te mehua mowhiti miro, ka piua te pito o te mehua piu ki te mehua piu (mowhiti mowhiti) kia ngawari, engari kaua ko te mehua kore-mutu (mowhiti inea).

Ko te pito o te kaitaki tohu o te miihini tohu tohu e hono ana ki te mehua mowhiti miro kaore e taea te whiu ki te mehua haere (mowhiti mowhiti) te mehua kore-mutu ranei (mehua mowhiti). I te wa e tirotiro ana me te tirotiro i te mowhiti mowhiti miro, ka whakaaetia kia tirohia nga paerewa whaitake mo te maha o nga niho ka uru atu te mehua haki ki te mehua mowhiti.

Whai muri i te whakatikatika i te korero, whakahokia nga taputapu whakatika kia kore e kino.

Kaore e taea te whakahaere i te mehua plug ina tirohia ana te koki miro me te ware.

 

Te inenga e toru-titi o te mehua plug miro

 

(1) Te hanga i te diameter diameter o te mehua miro aho.

Ko te tikanga ngira e toru-ngira ka taea te whakamatautau. E ai ki te P (pitch) me te koki miro (α) o te mehua miro, ka tohua te diameter ngira pai rawa atu hei whakatau i te

tohu o te mehua pereki tīwiri.

7. Te whakamahi me te tiaki i te mehua

 

• Ko te mata mehua o te mehua kia kore ai e waikura, e poke ranei;

• Kia mau te hononga i waenga i te mehua me te kakau;

• Ko te pakeke ko 58 HRC65 HRC;

• Ko te taha ahokore o te mehua e tutuki ana i nga whakaritenga paerewa;

• Ko te pakeke o te mehua ko 0.32μm;

• Te tirotiro i ia wiki kia rite ki te tikanga whakamahi

• Me tirotirohia te mehua plug i roto i nga marama 4-6 i muri i te whakamahinga a nga kaiwhakahaere wheketere;

• Ka taea te whakamahi i te mehua mowhiti mo nga ra 20 ki te 1 marama i roto i te wheketere, ana me tirotiro.

• Whakatauhia te whakamahi tika i te kaute mo te mehua;

• Me wehe ki te mehua mahi me te mehua manakohia.
