Dacromet pania hexagonal cylindrical tīwiri mahunga: He raka iti e whakatau i te ora o taputapu nui-tauine, anti-waikura me te waikura-ātete, a kahore he ati huna o te hauwai embrittlement.

1. Kupu Whakataki: Ko te Pounamu e mau ana i nga Miihini

Haere i roto i te toa miihini, te pūtau karetao, te nacelle hau-huripi ranei ka kitea e koe te whakamau kotahi ano: he mahunga porotakaro me te reanga hexagonal, kua herea ki te ki Allen. Ko tenei te hexagon socket head screw, kua whakaritea hei DIN 912 me te ISO 4762. Ko te raka taunoa mo nga miihini mate, nga taputapu miihini, nga manifolds waipēhi, me nga huihuinga tika, na te mea ka whakakorikori i te kawenga rawhi teitei i roto i te kopaki kiato ka taea te whakahoki ki roto i te porotiti.

2. Whakamaramatanga Hua: Hexagon Socket Head Cap Screw

Ko te ahuahanga o tenei raka he mea arotau mo te utaina, kaua mo te ahua oma:

Mahunga porotakarome te mata papatahi e tohatoha ana i te kawenga rawhi ki runga i te waahi porohita katoa.
Hexagon turanga o roto(whakaritea puta noa i nga papa mai i te 2.5 mm ki te 36 mm), te tuku taipana ki roto i nga mata e ono me te iti o te kamera-waho.
Miro inenga-katoa(te kara, te ware pai ranei mo ia ISO 261), ka hurihia kia kaua e tapahia kia rere tonu te witi me te pai ake o te oranga ngenge.
Nga karaehe taonga 8.8, 10.9, me 12.9, e hipoki ana i te kaha tensile mai i te 800 ki te 1,220 MPa.

Miro	Upoko Dia. (dk)	Teitei o te Upoko (k)	Tupapa Hex (s)	Akomanga 8.8 Tensile	Class 12.9 Tensile	Roa noa
M5	8.5 mm	5.0 mm	4 mm	800 MPa	1,220 MPa	10–60 mm
M6	10.0 mm	6.0 mm	5 mm	800 MPa	1,220 MPa	12–80 mm
M8	13.0 mm	8.0 mm	6 mm	800 MPa	1,220 MPa	16–100 mm
M10	16.0 mm	10.0 mm	8 mm	800 MPa	1,220 MPa	20–120 mm
M12	18.0 mm	12.0 mm	10 mm	800 MPa	1,220 MPa	25–150 mm
M16	24.0 mm	16.0 mm	14 mm	800 MPa	1,220 MPa	30–200 mm

Ko te tauwehenga o te upoko-ki-miro he mea nui mo te hoahoa waikura: ma te upoko porotakaroa nui e hoatu te paninga he mata whanui, he iti te ahotea hei hono atu, ko te riu turanga hohonu te rohe tino whakakikoruatia o te wiri katoa - kei reira te waikura ka whakaeke tuatahi me te kiriata angiangi, kaore ranei i oti te hopu i te raka.

3. Tāuta: Torque, Preload, me te Whakawhitiwhiti Whakakikorua

He horihori te raka atete ki te weriweri te hononga. Ko te Ripanga 2 he taipana whakahiato mo te akomanga 8.8 me te 10.9 te turanga potae potae mahunga me te paninga Dacromet (μ ≈ 0.14).

Miro	Class 8.8 Torque	Class 8.8 Preload	Class 10.9 Torque	Class 10.9 Preload
M5	6.5 N·m	4.0 kN	9.0 N·m	5.6 kN
M6	11.5 N·m	5.7 kN	16.0 N·m	8.0 kN
M8	28.0 N·m	10.4 kN	39.0 N·m	14.6 kN
M10	55.0 N·m	16.5 kN	78.0 N·m	23.1 kN
M12	96.0 N·m	24.0 kN	135 N·m	33.6 kN
M16	240 N·m	45.0 kN	335 N·m	63.0 kN

Whakamahia te kī tika.Ko te taviri Allen kua pau, he iti ranei te rahi ka pakaru te turanga, ka kitea te rino kore - te waahi tika ka tiimata te pirau.
Whakahonoretia te counterbore.Ka noho te upoko ki runga i te mata o tona mata; ko te porowhita kua pakaru, kua pakaru ranei ka whakaiti i te waahi whakapiri, ka pakaru te kiriata paninga i raro i te kawenga.
Kaua e whakaranuhia nga punaha paningai runga i te hononga kotahi me te kore e tirohia ano te taipana. He rereke te waku o te hurihanga Dacromet ki roto i te nati noa i te wiri pani ki te nati pania.
Re-torque i muri i te whakataungai runga i nga putea ngohengohe, i nga whare kirihou ranei; e kore e ngokingoki te kiriata maroke, engari ka taea e te mea rawhi.

4. Whakamutunga

Ko te Dacromet-coated hexagon socket head screw he waahanga iti e whakatau ana i te oranga ratonga o te huihuinga nui. Ko tana upoko porotakaroa me te hexagone o roto e tuku ana i te rawhi mo nga miihini hou; ko tana paninga tawerewere konutea-konumohe e tuku ana i te mahi aukati i te waikura e hiahiatia ana e te ratonga o waho, moana, me te kawe waka - kaore he hauwai, karekau he miro miro ano, karekau he whiu o te kowiri tira. Tauwhāitihia te hanga kia tika, kia tika te taipana, a ka roa ake te raka i te peita o te miihini e mau ana.

Kaore i whai. Whai muri.
