Loj ob chav helical iav yog cov khoom tseem ceeb hauv cov tshuab mining hnyav, qhov chaw uas lawv ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj zog sib kis tau zoo thiab muaj kev ntseeg siab ua haujlwm.

Nov yog cov ntsiab lus ntawm cov iav no thiab lawv qhov tseem ceeb hauv kev lag luam mining:

1. Tsim thiab tsim kho

Ob chav helical iav, kuj hu uaherringbone iav, feature ob pawg ntawm cov hniav helical angled nyob rau hauv opposite lus qhia. Qhov kev tsim no tso cai rau kev sib txuas hniav txuas ntxiv, uas yuav pab tau:

• Faib Load evenly: Cov txheej txheem ob ntawm cov hniav nthuav dav lub nra ntawm lub iav, txo qhov kev ntxhov siab ntawm txhua tus hniav thiab txhim kho lub iav tag nrho lub zog thiab ua haujlwm ntev.
• Tshem tawm Axial Thrust: Tsis zoo li ib qho helical iav, ob lub helical iav tsis tsim cov axial thrust rog tseem ceeb. Qhov no tshem tawm qhov kev xav tau ntxiv rau cov kabmob thrust bearings thiab txo cov complexity ntawm lub gearbox tsim.

2. Cov txiaj ntsig hauv kev siv mining

Hnyav Load Handling: Kev lag luam mining feem ntau koom nrog cov cuab yeej loj, xws li crushers, mills, thiab conveyors, uas ua haujlwm hauv cov khoom hnyav. Ob chav helical iav yog tsim los tswj cov khoom siv siab no kom zoo yam tsis muaj kev cuam tshuam kev ua haujlwm.

Ua haujlwm du thiab ntsiag to: Kev koom tes tas mus li ntawm cov hniav hauv ob chav helical iav ua rau kev ua haujlwm zoo dua thiab ntsiag to piv rau cov iav ncaj los yog ib qho helical. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov chaw mining uas txo cov suab nrov tuaj yeem ua rau muaj kev nyab xeeb thiab xis nyob hauv chaw ua haujlwm.

Siab Torque Transmission: Cov iav no muaj peev xwm kis tau lub siab torque nrog tsawg heev backlash, ua rau lawv zoo tagnrho rau cov ntawv thov kom meej thiab txhim khu kev qha fais fab hloov.

3. Kev xav txog kev tsim khoom

Kev xaiv khoom: Cov ntaub ntawv muaj zog xws li alloy steels lossis hardened steel yog siv los tsim ob chav helical iav rau mining. Cov ntaub ntawv no raug xaiv rau lawv cov kav ntev thiab muaj peev xwm tiv taus cov xwm txheej hnyav uas feem ntau ntsib hauv kev ua haujlwm tsuas.

Precision Machining: Cov txheej txheem tsim khoom suav nrog cov txheej txheem machining thiab cov txheej txheem tiav los xyuas kom meej cov hniav profile thiab pom cov iav meshing. Qhov no precision yog qhov tseem ceeb rau kev tswj xyuas kev ua tau zoo thiab txuas ntxiv lub iav qhov kev pab cuam lub neej.

Kev kho cua sov: Txhawm rau txhim kho lub hardness thiab hnav tsis kam ntawm lub zog, cov txheej txheem kho cua sov xws li carburizing lossis quenching yog siv. Qhov no txhim kho lub iav lub peev xwm los tuav cov khoom hnyav thiab tiv taus hnav lub sijhawm.

4. Cov ntawv thov hauv Mining

Gearboxes rau Crushers thiab Mills: Ob chav helical iav feem ntau yog siv nyob rau hauv gearboxes uas tsav crushers thiab sib tsoo mills, qhov twg siab torque thiab durability yog qhov tseem ceeb rau kev ua ore thiab minerals.

Conveyor Systems: Hauv mining conveyor systems, ob chav helical iav yog ua hauj lwm los tsav loj conveyor siv uas thauj cov khoom siv mined. Lawv lub peev xwm los tuav cov khoom hnyav thiab ua haujlwm zoo yog qhov tseem ceeb rau kev tswj xyuas cov khoom siv tau zoo.

Drilling thiab Excavation Equipment: Mining drills thiab excavators kuj tso siab rau ob chav helical iav los tuav lub zog hnyav uas yuav tsum tau ua rau kev ua haujlwm drilling thiab khawb.

Nyob rau hauv cov ntsiab lus, loj ob chav helical iav yog qhov tseem ceeb hauv kev lag luam mining vim lawv muaj peev xwm ua haujlwm siab, muab kev ua haujlwm du thiab ntsiag to, thiab xa cov kev ua tau zoo raws li qhov xav tau. Lawv cov qauv tsim muaj zog thiab kev tsim khoom raug ua rau lawv ua tau zoo rau qhov chaw hnyav thiab cov ntawv siv hnyav hnyav hauv kev ua haujlwm tsuas.
