5 Hom Sib Txawv ntawm Cov Gears & Lawv Cov Ntawv Thov

Ib lub iav yog ib qho khoom siv kho tshuab tshwj xeeb uas yuav txheeb xyuas tau los ntawm nws cov hniav uas tau txiav ib ncig ntawm ib qho chaw uas yog puag ncig, khoob, lossis zoo li lub khob hliav qab thiab muaj qhov sib txawv zoo sib xws. Thaum ob qho ntawm cov khoom no tau sib dhos ua ke, lawv tau muab tso rau hauv cov txheej txheem uas hloov cov kev sib hloov thiab lub zog los ntawm lub qag tsav mus rau lub qag txiav txim siab. Keeb kwm ntawm cov iav yog thaum ub, thiab Archimedes hais txog lawv siv hauv tebchaws Greece thaum ub hauv xyoo BC.

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

 

Miter Gear

Cov no yog cov hom iav bevel tseem ceeb tshaj plaws, thiab lawv qhov sib piv ceev yog 1. Lawv tuaj yeem hloov qhov kev taw qhia ntawm lub zog xa mus yam tsis cuam tshuam rau qhov nrawm xa mus. Lawv yuav muaj qhov teeb tsa linear lossis helical. Vim tias nws tsim lub zog thawb hauv qhov kev taw qhia axial, cov iav mitre spiral feem ntau muaj lub zog thawb txuas rau nws. Angular mitre iav zoo ib yam li cov iav mitre txheem tab sis nrog lub kaum sab xis uas tsis yog 90 degrees.

 

Spur Gear

Cov qag sib luag yog siv los xa lub zog siv cov iav spur. Tag nrho cov hniav ntawm cov iav spur pw hauv ib txoj kab ncaj nraim rau ntawm tus qag. Thaum qhov no tshwm sim, cov iav tsim cov khoom siv radial rau ntawm tus qag tab sis tsis muaj cov khoom siv axial.

 

Cov spurs feem ntau muaj suab nrov dua li cov iav helical ua haujlwm nrog ib kab sib cuag ntawm cov hniav. Thaum ib pawg hniav sib cuag nrog lub mesh, lwm pawg hniav nrawm mus rau lawv. Lub zog torque raug xa mus zoo dua hauv cov iav no thaum ntau cov hniav sib cuag.

 

Cov iav spur siv tau rau txhua qhov ceev yog tias suab nrov tsis yog qhov txhawj xeeb. Cov haujlwm yooj yim thiab tsis muaj zog siv cov iav no.

 

Bevel Gear

Lub bevel muaj qhov chaw pitch zoo li lub cone thiab muaj cov hniav khiav raws ntug ntawm lub cone. Cov no yog siv los hloov lub zog ntawm ob lub shafts hauv ib lub system. Lawv tau teeb tsa rau hauv cov pawg hauv qab no: helical bevels, hypoid gears, zero bevels; straight bevels; thiab mitre.

 

Cov Khoom Siv Herringbone

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

 

Cov iav sab hauv

Cov log pinion no koom nrog cov log cog sab nraud thiab muaj cov hniav txiav ua lub tog raj kheej thiab lub khob hliav qab. Cov no yog siv rau hauv cov iav sib txuas. Cov iav involute thiab trochoid muaj ntau yam iav sab hauv thiab sab nraud los tswj cov teeb meem thiab impedance.
