Khoom Taw qhia

Parameter rau 3M lub sij hawm siv:

Pitch 3

Hniav qhov siab 1.17

Txoj siv tawv thickness 2.40

3M ncig arc hniav: nws tuaj yeem ua tau raws li qhov sib kis tau zoo, thiab nws lub zog xa mus yog 3-5 npaug siab dua li ntawm tus ntaiv T tus hniav. Yog li ntawd, nws yog tsim nyog rau kev sib kis ib puag ncig ntawm lub zog siab, qis ceev thiab siab torque.

Synchronous siv tsav yog ib hom tshiab ntawm cov neeg kho tshuab tsav. Vim lub meshing kis tau tus mob, tsis muaj txheeb ze zawv zawg ntawm txoj siv thiab lub pulley, yog li kev sib kis ntawm tus tswv thiab qhev lub log yog synchronous. Lub sij hawm siv yog ua los ntawm cov khoom sib txawv. Lub zog thiab kev siv ntau lawm kuj txawv. Txoj siv tawv tiaj tiaj muaj qhov elasticity zoo thiab tuaj yeem ua haujlwm ntawm cov rub tawm me me, tab sis muaj qhov hloov tau zoo rau qhov sib txawv ntawm qhov sib txawv, tab sis qhov sib kis sib kis me me thiab yooj yim rau so.

Teeb meem xav tau kev saib xyuas thaum siv 3M siv sijhawm

(1) Kev pabcuam lub neej thiab cov hniav profile raug ntawm lub rubey muaj qhov cuam tshuam tseem ceeb rau kev sib kis ntawm txoj siv sia. Yog tias qhov kev pab cuam lub neej dhau mus, cov hniav hloov pauv, thiab cov hniav siv cov hniav thiab cov hniav rub tsis tuaj yeem mesh kom raug, txoj siv tawv synchronous yuav ua tsis tiav hauv lub sijhawm luv luv.

(2) Nyob rau hauv lub synchronous toothed txoj siv tsav, 3M lub sij hawm siv pulley, thiaj li yuav zam lub synchronous siv slipping los ntawm ib sab ntawm lub pulley, lub pulley yuav tsum muaj ib tug nres phaj, uas yuav tsum yog 1 ~ 2mm siab tshaj li nram qab no. siv thiab muaj inclination ntawm li 5 degree.

(3) Cov khoom siv thiab cov hniav hardness ntawm lub pulley muaj qhov cuam tshuam tseem ceeb rau kev sib kis zoo. Daim ntawv tsis ua haujlwm feem ntau ntawm txoj siv rubey yog cov hniav hnav thiab pitting corrosion, yog li txoj siv tawv hniav yuav tsum muaj kev hnav txaus thiab tiv taus lub zog. Cov kev tshawb fawb qhia tau hais tias cov roj hmab synchronous siv thiab cov khoom siv dav dav tuaj yeem yog cov pa roj carbon nruab nrab lossis nruab nrab carbon alloy cov qauv hlau, xws li 45 steel, 40Cr steel, 35si Mn steel, thiab lwm yam, uas yog normalized los yog quenched thiab tempered los ua tus hniav hardness ntawm 200 ~ 260hbs. Lub zog siab, qhov tawv tawv thiab zoo toughness tuaj yeem ua tau raws li qhov xav tau tiag tiag ntawm qhov project. Vim lub hardness nruab nrab, cov hniav profile tuaj yeem raug txiav kom raug tom qab kev kho cua sov.
