Qhov tseeb ntawm kab rov tav axis ntawm CNC tshuab dhos ua tshuab cuab yeej spindle lub thawv thiab ntsug axis ntawm lub hauv paus txiav txim siab qhov tseeb ntawm cov ntsia hlau yuav tsum ua tiav. Nyob rau tib lub sijhawm, thaum cov ntsia hlau tig ntawm kev kub ceev ntawm ntau txhiab kiv cua hauv compressor, cov ntsia hlau nrog qhov tseeb qis yuav ua rau compression. Tshuab cua sov, kev vibration, tsis tshua muaj efficiency, ceev hnav thiab lwm yam. Tam sim no, kuv lub teb chaws' qhov uas twb muaj lawm ib leeg-ntsia hlau ua tshuab cuab tam spindle qauv roughly muaj ob txoj kev hauv qab no.
Spindle qauv nrog unadjustable bearing radial clearance
Ob chav cylindrical cov menyuam bearing yog ua ke nrog ib khub ntawm thrust pob bearings. Ob chav cylindrical cov menyuam bearing yog siv los dais lub radial txiav quab yuam, thiab ob lub thrust pob bearings yog siv los dais lub axial txiav quab yuam. Ib khub ntawm ob kab cylindrical cov menyuam bearings los yog ib khub ntawm radial pob bearings, feem ntau yog ib khub ntawm rear bearings. Qhov zoo ntawm cov qauv spindle no: yooj yim ua thiab sib dhos, thiab tus nqi qis.
Spindle qauv nrog adjustable bearing radial clearance
Cov kabmob pem hauv ntej ntawm lub ntsiab ncej txais kev sib xyaw ua ke ntawm ob kab cylindrical cov menyuam bearings nrog P4 qib tapered bore thiab P4 ob-kab radial thrust pob bearing. Daim ntawv no qhia txog ob kab cylindrical cov menyuam bearing nrog tapered bore los tiv thaiv lub radial txiav quab yuam, thiaj li tiv taus lub axial txiav quab yuam thiab ib feem ntawm radial txiav quab yuam. Feem ntau, lub rear bearing ntawm lub ntsiab ncej yog ob tug cylindrical cov menyuam bearing nrog ib tug P5 tapered bore.
Lub nplhaib puab thiab qhov sib npaug ntawm txoj kab uas hla ntawm ob kab cylindrical cov menyuam bearings yog ob qho tib si 1:12 tapered. Xauv cov kabmob nrog cov txiv ntoo puag ncig tuaj yeem ua rau cov kabmob hloov mus rau hauv cov kev taw qhia axial thiab nthuav lub nplhaib puab ntawm cov kabmob kom txo lossis tshem tawm cov kabmob txoj kab uas hla. Rau lub hom phiaj ntawm clearance.
Qhov zoo ntawm cov qauv spindle: siab spindle raug. Qhov ntsuas qhov ntsuas ntawm lub ntsej muag kawg ntawm lub ntsej muag yog 0.010mm ntsuas ntawm φ230mm txoj kab uas hla nyob rau hauv pem hauv ntej ntawm spindle. Tus nqi dhia radial ntawm lub voj voog sab nraud yog 0.005mm, thiab qhov kawg ntawm lub ntsiab ncej yog φ230m. Qhov tseeb spindle ntawm cov qauv no yog kwv yees li 50% siab dua li qub.
