Npuag- qhwv txheej txheej thiab raw- ntug cogged geometry
Lub hauv paus txheej txheem sib txawv ntawmqhwv V-beltsthiabcogged V-sivlies nyob rau hauv lawv tus kheej tsim.Qhwv V- sivsiv cov ntaub npog tas mus li-feem ntau yog paj rwb lossis polyester- tiv thaiv lub hauv paus roj hmab los ntawm hnav, noo noo, thiab cov kab mob. Cov txheej tiv thaiv no kuj txo qis qhov hnav ntawm lub pulley, uaqhwv txoj siv siazoo tagnrho rau qias neeg lossis hnyav kev lag luam ib puag ncig. Piv txwv li,cogged V-sivmuaj ib tug raw -ntug tsim: ob sab nthuav cov roj hmab, thiab sab hauv nto tau precisely txiav transverse notches. Tshem tawm cov ntaub npog txo qhov nruj thiab kev sib txhuam, uas ua rau muaj kev ywj pheej ntau dua -tshwj xeeb tshaj yog nyob ib puag ncig me me pulleys. Cov notches no tsim airflow channel thaum lub sijhawm ua haujlwm, ntxiv kev txhim kho kev tswj hwm kub. Piv txwv li,cog cov hluatuaj yeem khoov ib ncig ntawm lub rubley nrog lub vojvoog li 30% me dua qhov sib npaugqhwv txoj sivthaum tseem tuav tuav thiab kev ncaj ncees.
Trapezoidal profile kev ncaj ncees thiab ua kom yooj yim los ntawm sab thaib
Kev tuav tus ntoo khaub lig trapezoidal meej - ntu yog qhov tseem ceeb rau kev ua kom zoo rau hauv lub pulley thiab xa cov torque kom ntseeg tau.Cov ntaub qhwvtuav cov duab no kom zoo-cov ntaub npog tiv thaiv sab deformation, kom ruaj khov kev sib cuag thiab nruj nreem nyob rau hauv siab loads. Txawm li cas los xij, qhov rigidity no nce khoov tsis kam, ua rau lub zog poob thiab kub tsim.Cogged sivtxhob txwm txiav txim siab geometric nruj nrog rau sab thais, ua zoo li cov pob khawm me me. Qhov no tso cai rau txoj siv hlua khi kom zoo nyob ib puag ncig me me - vojvoog pulleys yam tsis muaj kev cuam tshuam cov hlua. Qhov kev txo qis hauv kev khoov lub zog poob feem ntau tuaj yeem txhim kho kev tsav tsheb los ntawm 3-5% dhau cov qauv tsim. Engineers xaiv raws li qhov tseem ceeb: sivqhwv txoj siv siathaum qhov tseeb profile thiab kev tiv thaiv ib puag ncig yog qhov tseem ceeb; sivcog cov hluathaum qhov chaw txwv, kev kub ceev, lossis kev tswj xyuas kom sov yuav tsum tau ua kom yooj yim dua.
