Lub driveshaft yog ib qho tseem ceeb ntawm lub tshuab kis tau tus mob. Nws lub luag haujlwm tseem ceeb yog xa lub zog thiab lub zog los ntawm kev hloov pauv, ua tiav kev hloov pauv ntawm lub zog siv tshuab. Raws li lub hub tseem ceeb rau kev xa hluav taws xob, cov ncej tsav tau dav siv hauv tsheb, kev siv tshuab, nkoj, aerospace, thiab lwm yam, ua lub luag haujlwm tseem ceeb hauv kev sib txuas cov cav thiab cov khoom siv tsav.
Technical Principles thiab cov yam ntxwv ntawm tus yam ntxwv
Lub driveshaft feem ntau muaj peb ntu: ib lub raj raj, lub tes tsho telescopic, thiab kev sib koom ua ke thoob ntiaj teb. Lub raj raj yog cov qauv tseem ceeb, ua los ntawm siab - lub zog alloy steel los yog seamless steel tubing kom ruaj khov nyob rau hauv siab - kev sib hloov ceev thiab cov khoom hnyav. Lub tes tsho telescopic, txuas nrog lub spline, tso cai rau axial nplua -tuning, them nyiaj rau kev teeb tsa tsis raug lossis kev vibrations txhua yam, thiab tsis txhob muaj kev ntxhov siab los ntawm kev sib txuas nruj. Lub universal sib koom ua ke tso cai rau lub driveshaft smoothly xa hwj chim txawm nrog angular deviations. Hom hom muaj xws li ntoo khaub lig- hom, pob- hom tawb, thiab ob lub- hom sib koom, haum rau qis- nrawm nrawm- thauj khoom, siab- lub teeb nrawm- thauj khoom, thiab loj- lub kaum sab xis sib txawv raws li qhov xwm txheej.
Classification thiab Application Scenarios
Raws li kev sib txawv ntawm cov qauv, cov shafts tuaj yeem muab faib ua ob pawg: shafts nruj thiab hloov tau yooj yim:
Rigid Shafts: Haum rau cov kab sib kis los yog me me -angle offset scenarios, xws li tsav shafts nyob rau hauv tsheb rear-wheel drive systems. Kev xa hluav taws xob tau ua tiav los ntawm kev sib xyaw ua ke ntawm cov kav hlau txuas thiab cov pob qij txha universal, uas muaj cov qauv yooj yim thiab kev sib kis tau zoo.
Flexible Shafts: Siv cov khoom siv roj hmab los yog cov khoom sib txuas yooj yim, lawv tuaj yeem nqus tau kev co thiab kev poob siab, xws li cov ncej tsav hauv cov tshuab mining lossis cov khoom siv hlau. Cov shafts no yuav tsum tiv taus cov khoom hnyav, cuam tshuam, thiab nquag pib- nres lub voj voog, yog li yuav tsum muaj siab - cov ntaub ntawv toughness thiab cov txheej txheem kho cua sov tshwj xeeb.
Nyob rau hauv cov nqe lus ntawm daim ntawv thov scenarios, tsav ncej tsis yuav tsum tau customized raws li tej yam kev mob ua hauj lwm. Piv txwv li, tsav shafts hauv mining machinery yuav tsum muaj siab -torque, qis-ceev tsim (xws li, rated torque 1500 N·m, siab tshaj plaws ceev 1000 RPM) los tiv thaiv cov huab cua ua hauj lwm tej yam kev mob ntawm cov khoom xws li crushers thiab reducers; thaum automotive tsav shafts yuav tsum optimized lub teeb yuag tsim (piv txwv li, hnyav 5.5 kg, txheej txoj kab uas hla 155 mm) kom txo tau lub zog noj.
Kev lag luam Standards thiab kev xaiv xaiv Cov kev xaiv ntawm tsav shafts yuav tsum xav txog tag nrho cov torque, ceev, angular sib txawv, thiab tej yam kev mob. Cov qauv thoob ntiaj teb xws li ISO/DIS 1328-1 qhia meej cov kev cai rau iav precision, thaum cov qauv hauv tsev xws li GB/T 13264-2018 qhia cov kev txwv xws li qaug zog lub neej thiab kev sib npaug ntawm cov tsav tsheb. Piv txwv li, tsav shafts siv nyob rau hauv mining machinery yuav tsum xeem dhau dynamic tshuav nyiaj li cas (piv txwv li, qhov sib npaug qhov tseeb qib G2.5) kom tshem tawm tej zaum yuav muaj kev co txaus ntshai thaum lub sij hawm kev sib hloov ceev.
