Olunye ulwazi malunga nentambo

1. Umsonto Inkcazo

Umsonto ubhekiselele kwi-spiral shaped, protrusion eqhubekayo kunye ne-cross-section ethile eyenziwe kumphezulu we-cylindrical okanye i-conical base. Imisonto yahlulahlulwe yaba yimisonto yesilinda kunye nemisonto ekhonkoni ngokwemilo yomzali;

Ngokwendawo yayo kumzimba womzali, yahlulwe yaba yimisonto yangaphandle kunye nemisonto yangaphakathi, kwaye ngokwemilo yecandelo layo elinqamlezayo (imilo yezinyo), yahlulwe yaba yimisonto engunxantathu, imisonto exande, imisonto yetrapezoidal, imisonto exandiweyo, kunye nezinye. imisonto ekhethekileyo.

2. Ulwazi olunxulumeneyo

I-thread machining yi-protrusion eqhubekayo enemilo yezinyo echaziweyo eyenziwe kunye ne-helix kwi-cylindrical okanye i-conical surface. Iprotrusion ibhekisa kwindawo eqinileyo kumacala omabini omsonto.

Ikwabizwa ngokuba ngamazinyo. Ekuqhubekeni komatshini, imisonto isikwa kwi-cylindrical shaft (okanye umngxuma wangaphakathi) usebenzisa isixhobo okanye ivili lokugaya.

Ngeli xesha, i-workpiece ijikeleza kwaye isixhobo sihamba umgama othile kunye ne-axis ye-workpiece. Amanqaku asikwe ngesixhobo kwi-workpiece yimisonto. Umsonto owenziwe kumphezulu ongaphandle ubizwa ngokuba ngumsonto wangaphandle. Imisonto eyenziwe kumphezulu womngxuma ongaphakathi ibizwa ngokuba yimisonto yangaphakathi.

Isiseko somtya yi-helix ebusweni be-axis ejikelezayo. Iprofayile yomsonto inokwahlulwa ibe ziindidi ezahlukeneyo

Kukho iintlobo ezininzi zeeprofayili zemisonto:

Umsonto oqhelekileyo (intambo engunxantathu): Izinyo lalo limile ngunxantathu olinganayo, kunye ne-engile yezinyo ye-60 degrees. Emva kokuba imisonto yangaphakathi nangaphandle ifakwe ngaphakathi, kukho i-gap ye-radial, eyahlulahlulwa ibe yimisonto erhabaxa kunye necolekileyo ngokobungakanani bepitch.

Umsonto wombhobho: Ubume bezinyo lwemisonto yombhobho engatywinwanga ngunxantathu we-isosceles, kunye ne-engile yezinyo lee-degrees ezingama-55 kunye nekona enkulu engqukuva kumphezulu wezinyo.

Iimpawu zemilo yezinyo zemisonto yombhobho etywiniweyo ziyafana nezo zemicu yemibhobho engatywinwanga, kodwa ikudonga lombhobho weconical, kunye nemilo yezinyo ye-isosceles trapezoidal kunye ne-angle yezinyo lee-degrees ezingama-30.

Intambo yeTrapezoidal: Izinyo layo liyi-isosceles trapezoid, ene-angle yezinyo le-degrees ezingama-30, kwaye isetyenziswa ngokubanzi kwiindlela zokujija zokuhambisa amandla okanye ukunyakaza.

Umsonto weRectangular: Izinyo lalo limile lisikwere, kwaye i-angle yezinyo ilingana no-0 degrees. Inokuhanjiswa okuphezulu, kodwa ukuchaneka okuphantsi kweziko kunye namandla abuthathaka eengcambu.

Intambo ye-Serrated: Izinyo layo limile ngendlela engalinganiyo ye-trapezoidal, kunye ne-angle yeflank yezinyo ye-degrees ezi-3 kwindawo yokusebenza. Ingcambu yentambo yangaphandle inekona enkulu ejikelezileyo, kunye nokusebenza kakuhle kokuhanjiswa kunye namandla aphezulu kunemicu ye-trapezoidal.

Ukongezelela, kukho ezinye iintambo ezikhethekileyo ezimile, ezifana ne-V-shaped threads, i-Whitney threads, iintambo ezijikelezayo, njl.
