Tshiab High Quality Diesel Injector 10R4763 387-9428 Rau CAT C7 Injector Roj Injector Roj System

Los ntawm BiCkford, lub siab faib cheeb tsam ntawm cov khoom sib txuas yog sib npaug rau lub tog raj kheej hollow.BaCh xav tias qhov compressive kev ntxhov siab yog sib npaug ntawm qhov ntsug axis interface, thiab nws qhov loj ntawm qhov sib txawv ntawm qhov axial hloov pauv.Shigley coj lub kaum sab saum toj ib nrab raws li qhov sib txawv thiab tsis quav ntsej cov kev cuam tshuam ntawm kev tshem tawm thiab lub taub hau taub hau hloov ntawm qhov tawv nqaij, thiab tau txais tus nqi txhav los ntawm qhov sib txawv ntawm qhov sib txawv ntawm axial deformation.Sethuraman, Nassar thiab German Engineering Association tau txhim kho cov qauv kev nruj nruj los ntawm kev siv cov thickness, txoj kab uas hla thiab cov khoom siv rau hauv tus account.Yoshimura tau ua pov thawj los ntawm kev sim ua kom tag nrho cov tawv nqaij ntawm qhov sib koom ua ke tuaj yeem tau txais los ntawm kev sib koom ua ke ntawm kev sib koom ua ke ntawm qhov chaw sib koom ua ke.Nyob rau hauv Suav teb, xibfwb Yang Guoqing ntawm Xi 'an Jiaotong University tau qhia txog plaub qhov kev sib raug zoo ntawm kev xav tias qhov kev nyuaj siab ntawm cov txheej compression ntawm ntsug ntsia liaj qhov rooj axis nyob rau hauv txoj hauj lwm radial.Cov kev tshawb fawb qhia tau hais tias qhov zoo siab ntawm cov ntsia liaj qhov rooj sib koom nto muaj kev cuam tshuam zoo rau tangential dynamic yam ntxwv tsis.Nrog rau qhov nce ntawm qhov zoo siab, tangential contact stiffness nce thiab tag nrho cov damping sib txo.

Xyoo 1997, cov ntaub ntawv nthuav tawm ntawm European Machine Tool Exhibition tau pom tias 25% ntawm cov tuam txhab suav tias kev sib tsoo yog qhov tseem ceeb tshaj plaws machining tshuab lawv siv.Grinder suav txog 42% ntawm cov cuab yeej siv tshuab ua lag luam, thaum lathes tsuas yog 23% thiab cov tshuab milling suav txog 20%.Nyob rau hauv xyoo tas los no, nrog rau daim ntawv thov ntawm pob zeb diamond sib tsoo log thiab CBN sib tsoo lub log, txoj kev loj hlob ntawm spindle system, pub system, sib tsoo kua thiab txhaj tshuaj system thiab sib tsoo log so, sib tsoo muaj ib tug tseem ceeb txoj hauj lwm nyob rau hauv lub teb ntawm machinery manufacturing.
