Spur gears tuaj yeem siv tau thaum ob lub shafts sib npaug. Nqe lus piav qhia: Cov hniav raug txiav kom sib npaug mus rau qhov axis ntawm ncej.
Thaum shafts sib npaug li cas cov iav siv?
Bevel Gear
Bevel gears feem ntau yog siv los xa lub zog ntawm cov ncej uas sib tshuam ntawm 90 degree kaum. Lawv yog siv nyob rau hauv daim ntawv thov uas yuav tsum tau ib lub kaum sab xis iav tsav. Bevel gears feem ntau raug nqi ntau thiab tsis tuaj yeem xa cov torque ntau npaum li cas, ib qhov loj me, raws li kev sib txuas ntawm lub tog raj kheej.
Yuav siv cov iav twg yog tias ob lub axes?
Tsis muaj lus piav qhia rau lo lus nug no! 2) Kauv iavtsuas yog siv yog tias lub axes ntawm ob lub shafts tsis sib tshuam, tsis sib npaug thiab _. Kev piav qhia: Tsis muaj lus piav qhia rau lo lus nug no!
Thaum lub axes ntawm ob lub ncej tsis sib npaug thiab tsis sib tshuam?
Q9. Nqe Lus Qhia (I): Ob qhov tsis sib tshuam thiab tsis sib luag, piv txwv li, tsis yog-coplanar, shafts txuas nrog lub zog yog hu ua skew-bevel gears lossis kauv iav, thiab hom gearing no muaj ib kab hu rau kev sib hloov uas hais txog cov axes generates ob lub suab nrov hyperboloid.
Thaum lub axis ntawm ob lub shafts yog perpendicular thiab tsis sib tshuam siv lub iav twg?
Bevel Gear Ob lub iav mating feem ntau muab tso rau ntawm qhov sib tshuam sib tshuam ncej axes. Ib qho kev siv ntau tshaj plaws rau cov iav bevel yog hloov lub zog xa hluav taws xob axis.

Puas yog vikings siv ob lub taub hau axes?
ob axes tsis tau forged los ntawm NorseTsuas yog txhua axes lawv forged yog ib lub taub hau. Vikings feem ntau nqa cov axes khov kho uas tuaj yeem cuam tshuam los yog swung nrog lub taub hau-splitting quab yuam.

Tsuas yog tus txiv neej tseem ceeb hauv tsev yuav nyob twj ywm tawm hauv tsev ntev dua yog tias lub qhov rooj tig mus rau sab hnub poob thiab tus poj niam yog lub qhov rooj tig mus rau sab qaum teb .
Thaum lub sijhawm sib txuas ntawm cov protein hauv eukaryotes uas cov molecule dhau mus?
Messenger RNA (mRNA), molecule hauv cov hlwb uas nqa cov lej los ntawm DNA hauv cov nucleus mus rau qhov chaw ntawm cov protein synthesis hauv cytoplasm (cov ribosomes). Lub molecule uas nws thiaj li paub tias yog mRNA tau piav qhia thawj zaug hauv xyoo 1956 los ntawm cov kws tshawb fawb Elliot Volkin thiab Lazarus Astrachan .
Puas yog ib feem ntawm kev seev cev uas hais txog lub sijhawm ntawm kev txav mus los?
