Yam tseem ceeb cuam tshuam rau Leveling ko taw Hardness thiab Load-Bearing Capacity
Khoom yam ntxwv:
Lub hardness ntawm roj hmab leveling taw feem ntau yog li ntawm 60 txog 90 Shore A (saib ISO 7619 tus qauv). Cov hardness siab dua sib raug rau cov load ntau dua -cov kabmob muaj peev xwm, txawm hais tias nws ua rau txo qis kev vibration- damping kev ua haujlwm. Piv txwv li, ib qho kev sib tw nrog lub hardness ntawm 80 Shore A tuaj yeem txhawb nqa 50-100 kg, thaum ib tus nrog 90 Shore A tuaj yeem txhawb nqa ntau dua 150 kg.
Leveling taw ua los ntawm polyurethane los yog nylon yog haum rau siab -load daim ntaub ntawv (piv txwv li, 200-500 kg); Txawm li cas los xij, lawv xav tau lub hauv paus hlau kom muaj kev ruaj ntseg zoo dua.
Tus Qauv Tsim:
Ua kom cov cheeb tsam sib cuag-piv txwv li, los ntawm kev nthuav dav ntawm txoj kab uas hla ntawm 50 mm mus rau 80 mm-pab faib cov siab thiab tuaj yeem txhawb nqa cov load-cov kabmob muaj peev xwm los ntawm 10% mus rau 20%.
Caij nplooj ntoos hlav-cov qauv kev pabcuam pub rau kev hloov pauv ntawm qhov tawv tawv; Qhov kev sib tw nruj ntawm 5-15 N / mm yog pom zoo (saib daim ntawv * Mechanical Design Handbook*), ua rau lawv zoo tagnrho rau kev siv cov tshuab vibrating.
Kauj ruam-los ntawm-Cov kauj ruam qhia txog kev hloov kho
Hloov cov ntaub ntawv los yog Hardness Qib:
Yog tias kev vibration damping yog qhov tseem ceeb, xaiv cov roj hmab nrog lub hardness ntawm 60-70 Ntug A; yog tias siab load-yuav tsum tau muaj peev xwm, xaiv 80–90 Shore A roj hmab lossis hlau- cov ntaub ntawv sib xyaw.
Piv txwv li: Lub tshuab CNC tshuab tau tsim los nrog 70 Shore A leveling ko taw ( ntsuas rau 80 kg load) pom nws cov load-cov kabmob muaj peev xwm nce mus rau 120 kg (raws li cov ntaub ntawv sim tiag) tom qab tau hloov kho mus rau 85 Shore A ko taw.
Ua ntej- compression thiab qhov siab kho:
Kev pom zoo ua ntej - compression qhov tob ntawm 10% mus rau 15% ntawm tag nrho qhov siab yog pom zoo. Piv txwv li, ua ntej- compressing ib tug 100 mm siab leveling ko taw los ntawm 10 mm tuaj yeem txhim khu kev ruaj ntseg.
Rau threaded leveling taw, txhua qhov kev hloov pauv feem ntau hloov qhov siab li ntawm 2-3 hli; lub levelness ntawm cov cuab yeej yuav tsum tau soj ntsuam ib txhij nyob rau hauv cov txheej txheem no.
Ntxiv Cov Khoom Pab Txhawb Damping:
Txhim kho disc springs (piv txwv li, ua raws li tus qauv DIN 2093) tuaj yeem txhim kho kev poob siab thiab txhawb nqa dynamic load-cov kabmob muaj peev xwm los ntawm 30% mus rau 50%.
