Geometric Parameters yeTreads
Kunzwisisa Key Geometric Parameters
- Dhiyamita Yakakura (D kana d)
Hukuru dhayamita ndiro dhayamita rakakura kwazvo reshinda, rinoyerwa pachikiriso cheshinda dzekunze uye pamudzi weshinda dzemukati. Iyo inonyanya kutarisisa saizi yese yebhaudhi kana screw. Kudzora kwakaringana kweiyi parameter kunovimbisa kukodzera kwakaringana uye kusimba kwekubatanidza.
- Diki Diameter (D1 kana d1)
Diki dhayamita ndiro dhayamita diki diki reshinda, rinoyerwa pamudzi weshinda dzekunze uye pacrest kune shinda dzemukati. Inobata zvakananga kusimba kwesimba reshinda. Kunyatsogadzira dhayamita diki kwakakosha kuti uwane kubatanidzwa kwakakodzera pakati petambo dzekubatanidza.
- Pitch Diameter (D2 kana d2)
Chidimbu chenamo chiri pakati pakati pemadhayamita makuru nemadiki uye panokobvu kweshinda kunoenzana nzvimbo iri pakati peshinda. Iyo inonyanya kupesvedzera kukwana pakati peshinda uye yakakosha parameter yekuyera shinda chaiyo. Kuve nechokwadi chekuti dhayamita yepitch yakarurama inoguma nekugadzikana kurinani.
- Namo (p) - Metric
Pitch inoreva nhambwe yeaxial iri pakati pemachinjiro eshinda. Inokanganisa kukurumidza kwegungano uye kurongeka kwekubatanidza. Mapaji mahombe anofambisa kukurumidza kuungana asi anogona kuderedza simba rekubata, nepo matinji madiki achipa akasimba, akanyatso kubatanidza akakodzera kune yakakwira-mutoro maapplication.
- Thread angle (α)
Kona yeshinda ikona inosanganisirwa inoumbwa nemativi maviri emufananidzo weshinda. Makona akajairwa anosanganisira 60° yeshinda dzemetric uye 55° yeBritish Standard Whitworth (BSW) shinda. Makona akakura anowedzera kukweshana, achiwedzera kuzvivharira zvivakwa, izvo zvinobatsira kune yakagadzikana kubatana.
- Flank Engle (φ)
Rutivi (flank angle) ikona iri pakati pedivi reshinda uye mutsetse wakatarisana neaxis. Zvigadzirwa zvakasiyana zvinoenderana nezvinodiwa chaizvo:
Triangular Threads: Yakakodzera kune general-chinangwa kusungirira nekwakavimbika kuzvivharira.
Trapezoidal Threads: Yakanakira kurema-kuremerwa maapplication senge muchina maturusi madhiraivha.
Square Threads: Inoshanda pakutepfenyura kwemagetsi nekuda kwekudzika friction.
Sawtooth Threads: Inokodzera unidirectional kurodha mamiriro, senge mune hydraulic system.
- Thread Direction
Rudyi-Kurudyi Threads: Yakawanda, simbisa kana yakatenderedzwa wachi.
Mashinda ekuruboshwe: Anoshandiswa muhunyanzvi maapplication uko anti-kusunungura zvivakwa zvinodiwa, senge mune mimwe michina inotenderera.
Zvakajairwa Zvinotsanangurwa zvePitch uye TPI
Kusarudza gomo rakakodzera kana TPI kwakakosha kuti uve nechokwadi chekuita kwakanyanya. Pazasi pane mamwe anonyanya kushandiswa zvirevo:
- Metric Threads (Pitch)
M3: 0.5 mm
M4: 0.7 mm
M5: 0.8 mm
M6: 1.0 mm
M8: 1.25 mm (yakakora) / 1.0 mm (yakanaka)
M10: 1.5 mm (yakakomba) / 1.25 mm (yakanaka)
M12: 1.75 mm (yakakora) / 1.5 mm (yakanaka)
M16: 2.0 mm (yakakora) / 2.0 mm (yakanaka)
M20: 2.5 mm (yakakora) / 2.0 mm (yakanaka)
- Inch Threads (TPI)
#4-40 UNC/UNF: 40 TPI (UNC), 48 TPI (UNF)
#6-32 UNC/UNF: 32 TPI (UNC), 40 TPI (UNF)
#8-32 UNC/UNF: 32 TPI (UNC), 40 TPI (UNF)
#10-24 UNC/UNF: 24 TPI (UNC), 32 TPI (UNF)
1/4-20 UNC/UNF: 20 TPI (UNC), 28 TPI (UNF)
5/16-18 UNC/UNF: 18 TPI (UNC), 24 TPI (UNF)
3/8-16 UNC/UNF: 16 TPI (UNC), 24 TPI (UNF)
Iyo geometric paramita yeshinda yakakosha kune yavo mashandiro uye mashandisiro. Nekunzwisisa aya maparamendi uye nekusarudza iwo chaiwo maratidziro, mainjiniya anogona kuve neakavimbika uye anoshanda ekugadzirisa mhinduro dzakagadzirirwa kune chaiwo maapplication. Kunyangwe kusarudza metric kana yehumambo zviyero, iyo chaiyo musanganiswa wepitch uye TPI inovimbisa kuita kwakaringana uye hupenyu hurefu munzvimbo dzakasiyana dzeindasitiri.
