Lub coupling yog li cas?
1. Flange coupling
Flange coupling yog txuas ob ib nrab couplings nrog flanges nrog ob lub shafts nrog cov yawm sij tiaj tiaj, thiab tom qab ntawd txuas ob qhov ib nrab txuas nrog bolts kom xa cov lus tsa suab thiab lub zog. Qhov kev sib txuas no muaj ob lub ntsiab lus tseem ceeb:
(1) Los ntawm reaming qhov, ob lub shafts yog ua raws thiab nruab nrab ntawm bolts, thiab lub torque yog kis los ntawm compression thiab shear ntawm lub bolts pas nrig;
(2) Lub xub pwg nyom ntawm ib nrab sib txuas yog ua raws li qhov zawj ntawm lwm ib nrab txuas. Cov bolts txuas ntawm ob qhov sib txuas ib nrab tuaj yeem yog qib A thiab qib B zoo tib yam bolts, thiab cov torque kis tau los ntawm kev sib txhuam torque ntawm qhov sib koom ua ke ntawm ob ib nrab txuas.
2. Hla slider coupling
Qhov saum npoo ntawm 45 steel xav tau kev kho cua sov los txhim kho nws cov tawv nqaij; Q275 steel kuj tseem siv tau yam tsis muaj kev kho cua sov thaum cov kev xav tau tsawg. Txhawm rau txo kev sib txhuam thiab hnav, cov roj yuav tsum tau txhaj rau hauv cov roj qhov ntawm cov phaj nruab nrab rau lubrication. Tus ntoo khaub lig slider coupling, tseem hu ua hlau slider coupling, muaj ib ncig slider, uas yog tsav los ntawm steel los yog ib tug kis tau tus mob nrog tsawg ceev thiab loj kis torque.
Tus ntoo khaub lig slider coupling yog tsim los ntawm ob ib nrab couplings nrog grooves ntawm lub ntsej muag kawg thiab ib tug nruab nrab phaj nrog convex hniav ntawm ob sab. Vim hais tias cov hniav convex tuaj yeem xaub hauv qhov zawj, qhov sib txawv ntawm qhov sib txawv ntawm ob lub shafts thaum lub sijhawm teeb tsa thiab kev ua haujlwm tuaj yeem them rov qab. Txij li thaum ib nrab coupling thiab cov phaj nruab nrab tsim ib khub txav thiab tsis tuaj yeem tig tau zoo, lub kaum sab xis ntawm cov ncej tsav tsheb thiab cov ncej tsav yuav tsum sib npaug. Txawm li cas los xij, thaum muaj qhov sib txawv txav ntawm ob lub shafts, lub phaj nruab nrab yuav tsim lub zog centrifugal loj, uas yuav ua rau kom muaj zog thiab hnav. Yog li ntawd, thaum xaiv, nws yuav tsum tau muab sau tseg tias nws cov kev ua hauj lwm ceev yuav tsum tsis txhob yuav ntau tshaj qhov teev nqi. Hom kev sib txuas no feem ntau yog siv rau kev sib hloov ceev n<250r in,="" the="" rigidity="" of="" the="" shaft="" is="" large,="" and="" there="" is="" no="" severe="" impact.="" the="" transmitted="" torque="" is="" also="" small,="" which="" is="" generally="" used="" on="" small="">
3. Serpentine caij nplooj ntoos hlav coupling
Lub caij nplooj ntoos hlav serpentine yog embedded nruab nrab ntawm cov hniav ntawm lub flange ntawm ob coupling halves kom paub qhov elastic kev twb kev txuas ntawm ob coupling halves. Thaum lub sij hawm ua hauj lwm, lub torque yog kis los ntawm ib tug ncej (ib nrab coupling) mus rau lwm lub ncej los ntawm lub caij nplooj ntoos hlav. Yog li ntawd, hom coupling no muaj kev ua haujlwm ntawm absorbing vibration thiab cuam tshuam.
4. Iav coupling
Hom kev sib txuas no tso cai rau ob lub shafts kom muaj axial, radial hloov chaw thiab axial deflection, yog li nws tuaj yeem ua kom lub installation nce thiab txuag nqi installation. Nws yog tsim los ntawm ob ib nrab ncej tes tsho nrog ib nrab hniav thiab ob ib nrab plhaub nrog cov hniav sab hauv. Lub tes tsho sab nrauv yog tsau rau ntawm ncej kawg nrog tus yuam sij, cov hniav ntawm lub vaj tse zoo ib yam nrog cov hniav ntawm lub tes tsho sab nrauv, ob lub tsho ntawm lub tsev yog bolted thiab tsau, thiab cov roj lubricating yog txhaj rau hauv vaj tse kom txo tau qhov hnav ntawm cov hniav. Hom kev sib txuas no tuaj yeem txuag hluav taws xob, xa cov torque loj thiab muaj cov kev xav tau qis rau nruab nrab, tab sis nws cov damping thiab cushioning muaj peev xwm me me.
