Zoo Zoo Diesel Roj Txhaj Twj BH4PN120R Cav Qhov Chaw rau WEICHAI TD226B-4

Raws li qhov kev sib txhuam tseem ceeb ntawm cov twj tso kua mis roj, cov yam ntxwv ntawm cov kabmob muaj qhov cuam tshuam tseem ceeb rau kev ua haujlwm, kev cia siab thiab lub neej ntawm cov twj tso kua mis. Roj twj tso kua mis conveying nruab nrab rau cov roj viscosity tsawg, nyob rau hauv lub siab load thiab kev kub ceev tej yam kev mob, qhov tsawg kawg nkaus roj zaj duab xis thickness ntawm zawv zawg bearing yog heev nyias, yeej ib txwm txiav txim siab ntawm magnitude nrog lub nto roughness ntawm qhov chaw, yooj yim rau hnav thiab tsim kua muag. thiab yog li ua rau tsis ua hauj lwm ntawm cov roj twj tso kua mis zawv zawg bearing. Nyob rau hauv lub lubricating nruab nrab viscosity thiab load ib tug tej yam teeb meem, zawv zawg bearing clearance ratio (hais txog cov kev taw qhia ntawm zawv zawg bearing thiab ncej txoj kab uas hla clearance thiab ncej txoj kab uas hla ratio) yog lub ntsiab yam tseem ceeb ntawm qhov tsawg kawg nkaus zaj duab xis thickness, uas nyob rau hauv lem muaj feem xyuam rau cov kabmob. muaj peev xwm.

Yog li ntawd, txhawm rau daws qhov teeb meem uas zawv zawg bearings ntawm cov roj iav twj tso kua mis yog nquag hnav vim cov roj nyias nyias nyias, uas ua rau tsis ua haujlwm ntawm cov zawv zawg bearings nyob rau hauv lub siab load thiab kev kub ceev tej yam kev mob, thiab nyob rau hauv view ntawm lub sliding bearings. qhov tseeb hais tias qhov clearance ratio yog lub ntsiab influencing yam tseem ceeb ntawm qhov tsawg kawg nkaus roj zaj duab xis thickness ntawm zawv zawg bearings, zawv zawg bearings ntawm ib tug tej yam roj twj tso kua mis yog muab raws li ib tug kev tshawb fawb khoom yuav tsum tau kawm thiab soj ntsuam los ntawm PumpLinx simulation los txiav txim qhov tsawg kawg nkaus roj zaj duab xis thickness ntawm bearings, lub load nqa peev xwm, lub siab thiab kub tis ntawm bearings nrog txawv clearance ratios. Qhov tsawg kawg nkaus roj zaj duab xis thickness, load peev xwm, siab thiab kub tis ntawm bearings nrog txawv clearance ratios yog soj ntsuam los ntawm PumpLinx simulation. Flexural deformation ntawm lub iav ncej ntawm ib lub twj tso kua mis roj yog tshuaj xyuas, thiab tom qab ntawd kev sib raug zoo ntawm cov zawv zawg bearing clearance piv thiab qhov tsawg kawg nkaus roj zaj duab xis thickness, load peev xwm, bearing kub thiab kev faib ntawm circumferential thiab radial pressures yog soj ntsuam nyob rau hauv ob qho kev ua hauj lwm tej yam kev mob. , piv txwv li, qhov tsawg kawg nkaus ceev thiab qhov siab tshaj plaws ceev ntawm lub twj tso kua mis, feem. Cov txiaj ntsig tau pom tias: ntawm qhov sib piv ntawm qhov sib npaug, qhov zawv zawg kabmob muaj peev xwm nce thaum cov roj zaj duab xis thickness txo qis; thaum lub clearance piv txo, lub peev xwm bearing nce; thaum qhov ceev nce, cov kabmob muaj peev xwm nce; nyob rau hauv cov nqe lus ntawm ob qho tib si lub siab tis thiab kub nce, qhov zoo tshaj plaws qhov teeb meem yog pom thaum lub haum clearance piv ntawm lub iav ncej thiab zawv zawg bearing yog qhov tsawg tshaj plaws.
