Hom Cov Ntsiab Lus

Parallel key

Cov yuam sij sib npaug yog lwm yam hu ua cov yuam sij ncaj thiab lawv tau ua los ntawm cov xwm txheej thiab cov duab plaub. Cov no yog cov yuam sij siv tshaj plaws. Raws li txoj cai dav dav, lub ncej muaj ib lub qhov uas khiav nws tag nrho ntev uas yog tuav tus yuam sij los yog lwm txoj hauv kev, ib lub qhov uas ntev dua tus yuam sij uas pib thaum kawg ntawm lub ncej. Thaum lub sij hawm kev teeb tsa, cov qhov tseem ceeb ntawm cov ncej thiab cov khoom sib xyaw ua ke, thiab tom qab ntawd tus yuam sij sib npaug yog nias rau hauv.Thaum cov yuam sij ncej tuaj nyob rau hauv ob peb hom thiab hom, cov yuam sij thaum uas tig mus tseem siv tau ntau tshaj plaws thiab ntau. cov yuam sij tiaj tus thiab yog txhua yam khoom siv. Cov shafts nyob ib ncig ntawm 1.0 mus txog 20in inch. Nws qhov dav yog ua kom siab tshaj qhov siab yog li nws muaj peev xwm kis tau ntau dua torque tab sis tsis ntxiv qhov tob rau lub ncej thiab tsis ntxiv qhov tob qhov tob rau qhov tseem ceeb. Cov shafts no muaj ntau tshaj li 11 nti diameters thiab siv cov yawm sij, lawv feem ntau yog milled tiaj tus ntawm lawv qhov ntev, es tsis ua hauj lwm nrog rau qhov tseem ceeb. Cov khoom sib dhos ua rau siv tus qauv broached-keyway. Cov yuam sij Parallel pheej yig dua li lwm tus, lawv tau yooj yim thiab yooj yim rau nruab. Lub qhov tseem ceeb ntawm tus ncej yuav raug txiav siv qhov kawg zeb los yog nrog lub voj voog. Tom qab kev teeb tsa, ib lub ntsia hlau lossis lwm yam khoom siv khaws cia yuav tsum tau siv los tuav tus yuam sij sib npaug hauv txoj hauj lwm raws li nws cov khoom mounted. Ib tug tsav nyob rau hauv rov qab kev taw qhia los yog ib tug vibrating tsav feem ntau ua rau cov ntsia hlau loosen. Thaum qhov no tshwm sim, cov yuam sij sib npaug yuav txav tawm ntawm lub rooj sib txoos.

Saddle yawm sij

Cov yawm sij eeb yog cov yuam sij uas feem ntau txuas nrog lub caij tsav (piv txwv li, ncej). Cov yawm sij no paub tias muaj zog tsawg dua piv txwv li, cov yuam sij poob. Cov yawm sij no yog siv los xa cov hluav taws xob tsawg rau cov khoom tsav, los ntawm cov couplings.

Cov yuam sij tangent

Lub siab torque thiab lub luag haujlwm hnyav siv cov yuam sij Tangent. Txoj kev tseem ceeb zoo ib yam li tus yuam sij thaum uas tig mus, tshwj tsis yog tias nws tangentially nthuav tawm ntawm sab nrauv mus rau hauv lub puab ncej. Dab tsi yuav yog ib sab ntawm txhua txoj kev tseem ceeb yog lub pob taws tiv thaiv uas tus yuam sij nyob thiab xa lub zog compressive. Qhov kawg taw tes no qhia tau hais tias rau ib tug reversible tsab ntawv tsa suab, yuav tsum tau lwm tus yuam sij nrog rau ib tug tangent sab nraud nyob rau hauv lub opposite direction. Feem ntau, qhov no yog them los ntawm 90 degree lossis 180 degree ntawm lub ncej. Tus yuam sij yuav yog cov duab plaub, square lossis duab plaub, tab sis feem ntau yog siv cov duab plaub thiab ob lub taper.

Woodruff yuam sij

Cov yuam sij Woodruff feem ntau yog ib feem ntawm lub voj voog thiab yog ib feem haum rau hauv cov ntu ntu qhov tseem ceeb, qhov seem yog haum rau qhov ntev ntawm qhov sib txuas. Yog tsis muaj kev pab cuam, cov ntu ntu tuaj yeem raug txiav ncaj qha nrog lub plunge txiav siv lub voj voos ntoo. Lub ntsiab kom zoo dua ntawm Woodruff tus yuam sij yog tias tsis tas yuav tsum tau milling nyob ze ntawm cov npoo ntawm cov ncej, qhov twg yuav muaj kev sib haum xeeb nyob rau hauv lub concentration ntawm qhov nro, yog li tsis muaj concentricity yuav cuam tshuam.Qhov kawg yog qhov tsim nyog rau qhov siab. - kev ua haujlwm ceev. Qhov nruj dua ntawm tus yuam sij thiab qhov tseem ceeb txo qhov chaw thiab qhov nro concentration thiab txhim kho cov yuam sij kev ntseeg tau. Ib qho txiaj ntsig ntxiv yog tias thaum muaj qhov yuam sij daig, nws tuaj yeem raug tshem tawm ntawm lub ncej los ntawm lub tshuab rauj. Lub voj voog profile thawb tus yuam sij tawm ntawm lub qhov, tsis zoo li tus qauv yuam sij uas yuav tsum tau thawb axially lossis tshem tawm ntawm qhov. Cov kev siv feem ntau ntawm qhov no yog nyob rau hauv cov cuab yeej siv tshuab, cov tshuab daus daus, kev siv tsheb, thiab lwm yam.
