5 Ntau hom Gears & Lawv daim ntawv thov

Lub iav yog ib qho khoom siv tshwj xeeb uas yuav raug txheeb xyuas los ntawm nws cov hniav uas tau kos nyob ib ncig ntawm qhov chaw uas yog puag ncig, hollow, los yog lub khob hliav qab thiab muaj qhov sib piv. Thaum khub ntawm cov khoom no haum ua ke, lawv tau muab tso rau hauv cov txheej txheem uas hloov cov kev sib hloov thiab lub zog los ntawm kev tsav tsheb mus rau qhov kev txiav txim siab. Keeb kwm keeb kwm ntawm lub zog yog ancient, thiab Archimedes hais txog lawv siv nyob rau hauv ancient Greece nyob rau hauv lub xyoo BC.

peb yuav coj koj mus rau 5 hom iav sib txawv, xws li spur iav, bevel iav, ntsia hlau iav, thiab lwm yam.

 

Miter iav

Cov no yog cov hom phiaj tseem ceeb tshaj plaws ntawm bevel gears, thiab lawv qhov sib piv ceev yog 1. Lawv tuaj yeem hloov cov kev taw qhia ntawm lub hwj chim kis tau tus mob yam tsis muaj kev cuam tshuam rau tus nqi sib kis. Lawv tej zaum yuav muaj ib tug linear los yog helical configuration. Txij li thaum nws tsim thrust quab yuam nyob rau hauv cov kev taw qhia axial, kauv miter iav feem ntau muaj ib tug thrust bearing txuas rau nws. Angular miter iav yog tib yam li cov qauv miter iav tab sis nrog lub kaum sab xis uas tsis yog 90 degrees.

 

Spur iav

Parallel shafts yog siv los xa lub zog siv spur iav. Tag nrho cov hniav ntawm ib txheej ntawm spur iav yog nyob rau hauv ib txoj kab ncaj nraim nrog kev hwm rau lub ncej. Thaum qhov no tshwm sim, lub zog tsim radial cov tshuaj tiv thaiv loads ntawm lub ncej tab sis tsis muaj axial loads.

 

Spurs feem ntau nrov dua helical zog ua haujlwm nrog ib kab ntawm kev sib cuag ntawm cov hniav. Thaum ib txheej ntawm cov hniav ua rau kev sib cuag nrog cov mesh, lwm cov hniav nrawm nrawm rau lawv. Lub torque kis tau yooj yim dua nyob rau hauv cov iav no vim ntau cov hniav sib cuag.

 

Spur iav tuaj yeem ua haujlwm ntawm txhua qhov nrawm yog tias lub suab nrov tsis muaj kev txhawj xeeb. Cov hauj lwm yooj yim thiab me me siv cov cuab yeej no.

 

Bevel iav

Lub bevel muaj ib lub suab zoo li lub khob hliav qab thiab muaj cov hniav khiav raws ib sab ntawm lub khob hliav qab. Cov no yog siv los hloov lub zog ntawm ob lub shafts hauv ib qho system. Lawv tau teem rau hauv cov pawg hauv qab no: helical bevels, hypoid gears, xoom bevels; ncaj bevels; thiab mitre.

 

Herringbone iav

Kev ua haujlwm ntawm ib lub iav herringbone tuaj yeem muab piv nrog rau kev khaws ob lub iav helical ua ke. Yog li ntawd, lwm lub npe rau nws yog ob chav helical iav. Ib qho txiaj ntsig ntawm qhov no yog tias nws muaj kev tiv thaiv sab thrust, nyob rau hauv sib piv rau helical iav, uas ua rau sab thrust. Hom iav tshwj xeeb no siv tsis muaj zog quab yuam rau cov bearings.

 

Sab hauv iav

Cov log pinion no koom nrog cov cogwheels sab nraud thiab muaj cov hniav carved rau hauv lub tog raj kheej thiab cov cones. Cov no yog siv nyob rau hauv gear couplings. Involute thiab trochoid gears muaj ntau lub zog sab hauv thiab sab nrauv los tswj cov teeb meem thiab impedance.
