Urwego rusanzwe

Urukurikirane rusanzwe rwa diameter n'ikibanza (GB / T193-2003)

Ikigereranyo cya diametre hamwe nicyiciro gisanzwe cyo guhuza bigomba kubahiriza ingingo ya Imbonerahamwe 1. Mu mbonerahamwe, ikibuga kigomba gutoranywa kumurongo umwe na diamete

Inkingi ya diameter. Hitamo urukurikirane rwa mbere rwa diametre ubanza, urukurikirane rwa kabiri rwa diametre kabiri, hanyuma sisitemu ya Tertiary iheruka

Irinde guhitamo ikibuga mumutwe muto bishoboka.

Utudodo tubiri twihariye dufite inoti (a, b) mumeza igomba gukoreshwa gusa kubikoresha byihariye bisobanurwa

Urukurikirane rwihariye rwa diameter na pitch:

Ku bipimo bisanzwe bya diametre, niba ikibanza kidasanzwe ari gitoya kuruta uko bigaragara mu mbonerahamwe ya 1 gisabwa, kigomba gutoranywa muri ibi bikurikira:

3mm, 2mm, 1.5mm, 1mm, 0. 75mm, 0. 5mm, 0. 35mm, 0. 25mm, 0. 2mm

Guhitamo ikibanza gitoya kuruta icyavuzwe mu mbonerahamwe ya 1 bizongera ingorane zo gukora imigozi

Bihuye n'ikibanza kiri mu mbonerahamwe ya 2, ntarengwa ntarengwa ya diameter yatoranijwe ntigomba kuba hanze ya diameter yasobanuwe mu mbonerahamwe ya 2.

7.3 Kwihanganira hejuru ya diameter

a) Kwihanganira diameter nini yumurongo wo hanze:

Kwihanganira icyiciro cya 6: Ta (6) -180P3-3.15

Urwego rwa 4 kwihanganira: Ta (4) = 0,63Ta (6)

Kwihanganira icyiciro cya 8: Ta (8) = 1.6Ta (6)

Ta ipimirwa muri microne na P ipimwa muri milimetero.

b) Kwihanganira bike kurwego rwimbere:

Icyiciro cya 6 kwihanganira: 1) Iyo 0.2mm1mm: 1 (6) = 230P0.7

Urwego rwa 4 kwihanganira: Tpi (4) = 0,63 Tp (6)

. muri milimetero.

Kugabanya gutandukana (GB / T2516-2003)

Imipaka yo gutandukanya indangagaciro ya diameter yo hagati na diameter yo hejuru irerekanwa mumeza 1 (usibye).

Ingingo iyo ari yo yose ku mwirondoro wo hasi w’imbere n’inyuma ntigomba kurenza umwirondoro ntarengwa ugenwa nu mwirondoro wibanze hamwe n’ahantu ho kwihanganira. Agaciro ko gutandukana kwa diameter yimeza gatangwa ukurikije uburebure bwa H / 6, irashobora gukoreshwa mukubara impungenge zurudodo rwo hanze.

Icyitonderwa: Gutandukana kwa diameter ntoya yumurongo wo hanze ubarwa nka - (les + H / 6).Keretse niba byavuzwe ukundi, zone yo kwihanganira ikoreshwa kumutwe mbere yo gushiraho.Nyuma yo gushiraho, nta ngingo iri kumurongo wurudodo igomba kurenza igipimo kinini cyinyo yinyo igenwa nu mwanya wo kwihanganira umwanya wa H cyangwa h.Icyitonderwa: Imipira yo kwihanganira ikoreshwa gusa kumutwe.Kurugero, amashanyarazi.
