Kev taw qhia thiab kev daws cov suab nrov txawv txav ntawm lub caij nplooj ntoos hlav caij tsheb npav

Qhov kev txav ntawm nplooj ntoos hlav bushing nyob rau hauv nplooj ntoos hlav dov pob ntseg qhov yuav ua rau cov hlau tsis sib xws suab nrov. Lub ntsiab yog vim li cas rau qhov no yog hais tias lub puab txoj kab uas hla ntawm nplooj ntoos hlav yob pob ntseg yog tsis kam mus thiab tawm ntawm puag ncig, thiab cov hlau bushing phab ntsa yog nyias, uas ua rau cov nplooj ntoos hlav bushing yuav deformed thiab tawg nyob rau hauv lub extrusion ntawm lub bushing. nplooj ntoos hlav pin thaum lub sij hawm tsav tsheb ntawm lub tsheb, thiab lub phaj Lub caij nplooj ntoos hlav bushing yog tshwm sim los ntawm stringing nyob rau hauv lub lug qhov ntawm nplooj ntoos hlav.
Nws tuaj yeem ntxiv dag zog rau kev tswj xyuas zoo ntawm nplooj ntoos hlav dov pob ntseg tsim, nce phab ntsa thickness ntawm nplooj nplooj hlav bushing kom txo tau cov bushing deformation, thiab zoo zam lub bushing txav.
Poor lubrication between the leaf spring bushing and the leaf spring pin will also produce abnormal metal friction noise. The main reasons for poor lubrication are: improper maintenance, lack of grease, dry grinding between the leaf spring pin and bushing; unreasonable position of the oil outlet hole of the leaf spring pin, and the grease cannot be evenly distributed on the surface of the leaf spring pin. Local dry grinding occurs; during the assembly process of the leaf spring pin, the paint and metal chips on the leaf spring bracket are brought into the leaf spring bushing, so that local dry grinding occurs; some leaf spring bushings are still made of "powder metallurgy" material , the powder falls off and blocks the oil hole, causing dry grinding; the coaxiality between the leaf spring pin and the leaf spring bushing is poor, and the leaf spring pin and the leaf spring bushing are partially compressed, which cannot be lubricated, resulting in dry grinding.
Txhawm rau ua kom cov nplooj nplooj hlav pin zoo lubricated, ntxiv rau kev saib xyuas tsis tu ncua, lub tshuab lubrication tsis siv neeg tuaj yeem ntsia tau los txhim kho lub peev xwm lubricating, thiab cov roj kauv channel tuaj yeem ntxiv rau nplooj nplooj hlav pin thiab nplooj nplooj hlav bushing los txhawb cov txawm faib cov roj. Cov txheej txheem no tuaj yeem txo cov suab nrov txawv txav ntawm no.
Cov suab nrov txawv txav ntawm nplooj reed thiab nplooj. Nyob rau hauv ib txwm muaj ntau- nplooj springs, nplooj springs yog nyob rau hauv kev sib cuag ncaj qha. Tom qab lub tsheb khiav mus rau ib lub sij hawm, cov roj graphite ntawm cov nplooj springs yog tas, ua rau qhuav sib tsoo thiab suab nrov txawv txav. Qhov xwm txheej no tshwj xeeb tshaj yog nyob rau hnub tom qab los nag thiab daus. Siv cov roj lubricating thiab roj rau ntawm nplooj hlav tuaj yeem tshem tawm lub suab txawv txav ib ntus; nyob rau hauv tus tsim, ntxiv ib qho anti- txhuam txhuam ntawm qhov kawg ntawm lub ntsiab daim tuaj yeem txo cov suab txawv txav.
Cov suab nrov txawv txav ntawm lub caij nplooj ntoos hlav nplooj thiab tiv thaiv - txhuam txhuam. Anti- cov ntaub thaiv kev sib txhuam yog ntsia nruab nrab ntawm cov nplooj hlav ntawm ob qho kawg ntawm cov nplooj hlav me me kom txo cov suab nrov. Txawm li cas los xij, vim nws qhov kev sib txhuam me me thiab cov kev ntxhov siab nyuaj, txhawm rau ua kom tau raws li nws cov kev pab cuam lub neej, cov khoom siv nyuaj yog xaiv, uas yog qhov ua rau lub suab nrov tsis zoo nyob rau hauv lub xeev ntawm lub tsheb tshiab los yog thaum kub qis.
Yuav kom daws tau cov suab nrov txawv txav los ntawm lub phaj caij nplooj ntoos hlav tiv thaiv - txhuam txhuam, nws yog ib qho tsim nyog yuav tsum pib ntawm cov khoom thiab cov qauv ntawm cov khoom tiv thaiv - txhuam txhuam. Ua ntej tshaj plaws, tus kheej -lubricating khoom ntawm gasket yuav tsum tau nce, thiab cov khoom xws li molybdenum disulfide tuaj yeem muab ntxiv rau hauv lub gasket; thib ob, cov duab thiab cov qauv ntawm lub gasket yuav tsum tau kho dua tshiab raws li lub zog ntawm qhov kawg ntawm nplooj hlav.
Lub suab txawv txav ntawm nplooj ntoos hlav clamp yog tshwm sim los ntawm kev sib txhuam kev sib txhuam ntawm lub clamp thiab nplooj hlav thaum lub sijhawm ua haujlwm ntawm lub tsheb vim yog kev sib cuag ntawm ob sab ntawm lub clamp thiab nplooj hlav. Txhawm rau tshem tawm cov suab nrov txawv txav no, qhov dav ntawm lub clamp tuaj yeem nthuav dav los tsim kom muaj qhov sib txawv ntawm nws thiab nplooj hlav, lossis lub tes tsho roj hmab tuaj yeem ntxiv rau hauv lub clamp.
Hloov cov qauv ntawm nplooj nplooj hlav bushing tuaj yeem zam lub suab nrov txawv txav los ntawm ntau yam tsis zoo lubrication
1. Steel-backed roj hmab compound bushing. Lub hauv paus ntsiab lus ua haujlwm ntawm hom bushing no yog kev vam khom rau tus kheej - deformation ntawm cov roj hmab hauv cov sib xyaw bushing kom tsis txhob thiab tshem tawm cov kev vibration stroke hloov thaum lub sijhawm ua haujlwm ntawm lub tsheb. Txij li thaum nplooj nplooj hlav pin tsuas yog ua lub luag haujlwm nruj, tsis muaj kev sib txheeb nrog cov nplooj nplooj hlav bushing, yog li tsis tas yuav lubrication thiab tsis muaj suab nrov txawv txav.
2. Polymer khoom nplooj nplooj hlav bushing. Hom bushing no yog ua los ntawm cov khoom siv polymer xws li polyethylene. Nws muaj qee yam ntawm tus kheej -lubrication, hnav tsis kam thiab cuam tshuam tsis kam.
