Qhov zoo ntawm txoj siv pulley kis tau tus mob yog: txoj siv pulley kis kinetic zog los txo qhov cuam tshuam ntawm load; Txoj siv ruby rub tau yooj yim, tsis muaj suab nrov thiab kev co; Cov qauv ntawm txoj siv pulley kis tau tus mob yog yooj yim thiab yooj yim kho; Kev tsim thiab kev txhim kho qhov tseeb ntawm txoj siv pulley tsis nruj; Txoj siv pulley kis tau tus mob muaj nuj nqi ntawm kev tiv thaiv overload; Qhov kev hloov kho ntawm qhov chaw nruab nrab ntawm ob lub shafts uas tau tsav los ntawm txoj siv rubey yog qhov loj. Qhov tsis zoo ntawm txoj siv hlua kis tau tus mob yog: lub pulley kis tau tus mob muaj elastic zawv zawg thiab slipping, qhov kis tau tus mob yog tsawg thiab qhov tseeb kis tau tus mob piv tsis tau; Thaum siv txoj hlua rub rub kis tau zoo tib yam lub voj voog loj, qhov loj me thiab qhov siab ntawm lub ncej loj dua li ntawm qhov sib kis meshing; Lub neej kev pab cuam ntawm pulley tsav siv yog luv. Lub pulley txoj kab uas hla thiab lwm qhov ntev ntawm ntau yam khoom siv tshuab yog lawv tus kheej.
Nws yog tsim raws li qhov sib piv ntawm qhov ceev thiab kev ua haujlwm ceev thiab kev ceev ntawm lub cev muaj zog. Ua hauj lwm ceev / lub cev muaj zog ceev {{0}} tsav log txoj kab uas hla / tsav log txoj kab uas hla 0.98 (sliding coefficient). Yog tias siv cov hlau rub, lub linear ceev yuav tsum tsis txhob siab tshaj 40m / s. yog siv cam khwb cia hlau pulley, linear ceev yuav tsum tsis txhob siab tshaj 35m / s. Qhov sib piv ntawm lub cev muaj zog ceev thiab txoj kab uas hla, qhov sib piv ceev=tso zis ceev: input ceev=load pulley pitch txoj kab uas hla: lub cev muaj zog pulley pitch txoj kab uas hla. Lub suab diam yog tib yam li qhov siv txoj kab uas hla. Txoj kab uas hla - 2H=pitch txoj kab uas hla, h yog qhov zawj qhov tob ntawm kab siv, thiab H sib txawv rau cov qauv sib txawv ntawm V-siv. YZ ib BCDE, qhov tob tob ntawm kab siv yog h=1.6 2.75 3.5 4.8 8.1 9.6 raws. Pulley pitch txoj kab uas hla yog lub theoretical txoj kab uas hla ntawm pulley pitch kab txoj hauj lwm, uas yog ib tug me ntsis zoo li lub indexing lub voj voog txoj kab uas hla ntawm iav Nws yog feem ntau qhia los ntawm PD, thiab lub voj voog sab nrauv yog feem ntau qhia los ntawm OD Cov qauv hloov dua siab tshiab ntawm lub voj voog thiab lub voj voog sab nrauv ntawm sib txawv groove hom yog txawv. Feem ntau, peb tuaj yeem ntsuas lub voj voog sab nraud ntawm lub pulley thiab xam lub suab lub voj voog raws li cov qauv SPZ:OD=PD ntxiv rau 4; SPA:OD=PD ntxiv 5.5; SPB:OD=PD plus 7; SPC:OD=PD ntxiv rau 9.6. Qhov tsawg kawg nkaus txoj kab uas hla ntawm lub pulley ntawm ib tug los yog spa yog 80mm. Yog tias nws tsawg dua qhov loj me no, tshwj xeeb tshaj yog nyob rau hauv kev kub ceev, txoj siv tawv yuav ua rau delamination thiab tawg hauv qab. SPZ siv, lub log me me tsis pub tsawg dua 63 hli. Nyob rau tib lub sijhawm, xyuam xim rau txoj kev teeb tsa thiab kev nruj ntawm txoj siv. Yog tias nws me dhau, nws yooj yim plam, thiab yog tias nws loj dhau, nws yooj yim rau kev puas tsuaj rau txoj siv thiab cov kabmob.
Working principle of belt pulley: belt transmission belongs to "flexible transmission" in the basic mechanism of machinery - that is, the belt is used to connect two driving and driven parts that are not in direct contact, and the tension generated by friction is used to transmit motion and power.
Qhov txawv: daim ntawv thov ntawm V- siv lub rubey yog xa mus rau lub zog: kev ua haujlwm ntawm cov kabmob rub tawm yog los tiv thaiv txoj siv los ntawm kev xoob dhau (lossis lub kaum sab xis qhwv me dhau) thaum qhov kev sib kis ntev? Kev ua nruj, yog li nws tseem hu ua --? Tightening log (? log); Txoj kab uas hla ntawm lub pulley rau lub twj tso kua mis tuaj yeem txiav txim siab raws li tus naj npawb ntawm cov kiv cua xav tau.
Points of belt transmission: stable operation, low noise, protection from "slip" in case of overload, convenient manufacture, simple maintenance, suitable for transmission with large center distance.
