Super-precision ob kab cylindrical cov menyuam bearing nrog tapered bore thiab lubrication feature
High-precision cylindrical roller bearings feem ntau muaj lub nplhaib sab nraud, lub nplhaib sab hauv nrog lub qhov tapered, lub cylindrical roller thiab lub tawb. Lub nplhaib sab nrauv ntawm cov qauv feem ntau yog sib cais. Raws li tus naj npawb ntawm dov lub caij kab, lawv muab faib ua ib leeg-kab ultra-precision cylindrical bearings. Cov menyuam bearings thiab ob kab super-precision cylindrical cov menyuam bearings. Qhov no series ntawm bearings yog siv nyob rau hauv tej yam kev mob uas yuav tsum tau high precision thiab siab radial loads, thiab yog feem ntau siv nyob rau hauv lub tshuab cuab yeej siv.
Super-precision cylindrical roller bearings muaj xws li lub nplhaib sab nrauv, lub nplhaib sab hauv nrog lub qhov sib txuas sab hauv (taper 1: 12) lossis lub cylindrical qhov, cylindrical rollers thiab cov khoom hauv tawb. Cov khoom siv tawb yog tooj dag lossis PEEK. Lub nplhaib sab nraud yog tshem tau yog li nws tuaj yeem ntsia tau sib cais tom qab muab nws tawm ntawm lub ntim. Tsuas yog lub nplhaib puab ntawm NNU49 series yog tshem tau.
Ib-kab thiab ob-kab bearings yog siv nyob qhov twg yuav tsum tau precision thiab radial loads siab.
Feem ntau siv hauv kev lag luam cov cuab yeej precision, lawv ua kom muaj kev ua haujlwm siab-precision bearing nrog siab radial txhav thiab muaj peev xwm nqa tau siab heev. Hauv kev tsim, lawv muab kev txhawb nqa radial rau lub ntsiab ncej.
Cylindrical roller bearings yog tshwj xeeb tshaj yog haum raws li floating bearings vim hais tias tsis muaj kev sib khi quab yuam ntawm cov chais thiab cov ribless raceway, uas muaj peev xwm them rau cov kev hloov nyob rau hauv ntev thaum lub sij hawm tig. Lub axial quab yuam yog txhawb nqa los ntawm cov kabmob thrust, xws li bidirectional thrust angular contact pob bearings.
Standard series N10, N19, HCN10 (ib kab) thiab NN30, NNU49 (ob kab) yog ib feem ntawm SKL super precision bearings. Cov qauv tsis suav nrog hauv phau ntawv teev npe tuaj yeem muab los ntawm kev pom zoo.
Qhov me me hla ntu ntawm super-precision cylindrical cov menyuam bearing series N19 thiab NNU49 pab kom cov ncej me me nyob rau hauv ntau qhov kev npaj.
1. Ib kab cylindrical cov menyuam bearings
Ib kab ultra-precision cylindrical cov menyuam bearings muaj xws li: puab rings nrog tapered bores los yog cylindrical bores, hybrid cylindrical menyuam bearings nrog ib nrab rollers, thermal stability tsim, ncaj lubrication hom thiab lwm yam tsim.
Hauv N10 thiab N19 series, cov chais yog coj los ntawm lub nplhaib puab thiab sib cais los ntawm ib lub tawb ua los ntawm tooj dag lossis PEEK.
2. Hybrid cylindrical rollers nrog ib nrab rollers
Nyob rau hauv hybrid cylindrical roller bearings, cov khoom siv rau cov menyuam yog cov khoom siv ua haujlwm siab. Cov khoom no txo qis kev sib txhuam thiab hnav hauv cov kabmob. Ntxiv mus, qhov kev ntxhov siab nyob rau hauv lub lubricant yog txo, thiab cov bearing kub nce yog qis dua. Vim qhov piv txwv no, hybrid cylindrical cov menyuam bearings tuaj yeem ncav cuag qhov siab tshaj plaws ntawm txhua lub cylindrical roller bearings. Ntxiv mus, txij li lub thermal expansion coefficient ntawm ceramic rollers yog me me, qhov cuam tshuam ntawm kev nce preload los ntawm qhov kub thiab txias tuaj yeem txo. Nrog rau cov hybrid bearings no, lub neej kev khiav hauj lwm ntawm spindles thiab cov cav tov yog ho nce thiab lub kaw lus yuav ua tau ntau adaptable. Ceramic rollers kuj txhim kho zoo li qub thiab kev ua haujlwm zoo. Cov no muaj txiaj ntsig zoo rau kev ua haujlwm zoo.
Ib nrab ntawm cov menyuam hybrid cylindrical cov menyuam bearings muaj cov lus tom qab H193. Vim qhov txo qis ntawm cov chais, cov kabmob ceev tuaj yeem nce ntxiv, tab sis qhov nruj radial raug txo.
