Crankshaft txij nkawm txoj kev thiab cov kev cai ntawm engineering cranes: lub radial runout ntawm lub crankshaft thiab lub radial runout ntawm lub ntsej muag thrust ntawm lub axis ntawm lub ntsiab phau ntawv journal yuav tsum tau raws li cov kev cai. Txwv tsis pub, nws yuav tsum raug kho. Txheeb xyuas qhov yuav tsum tau ua kom tawv tawv ntawm crankshaft cov ntawv xov xwm thiab cov ntawv xov xwm sib txuas, uas yuav tsum tau ua raws li cov kev cai. Txwv tsis pub, nws yuav tsum tau rov ua dua kom tau raws li cov kev cai siv. Yog hais tias lub crankshaft tshuav nyiaj li cas bolt yog tawg, nws yuav tsum tau hloov. Tom qab lub crankshaft hloov qhov sib npaug ntawm qhov sib npaug los yog qhov sib npaug ntawm cov ntsia liaj qhov rooj, nws yog lub sijhawm los ua qhov ntsuas qhov sib npaug ntawm lub crankshaft los ua kom ntseeg tau tias qhov nyiaj tsis sib npaug raws li cov kev xav tau. Hnav-resistant electrode.

(1) Disassemble thiab ntxuav lub crankshaft Cheebtsam kom paub meej tias cov roj sab hauv ntawm lub crankshaft yog huv si thiab tsis thaiv.

(2) Ua qhov tsis txaus ntseeg ntawm lub crankshaft. Yog tias muaj qhov tawg, nws yuav tsum tau hloov. Ua tib zoo xyuas cov ntawv xov xwm tseem ceeb ntawm crankshaft, txuas cov ntawv xov xwm thiab nws txoj kev hloov pauv, thiab txhua qhov chaw yuav tsum tsis muaj khawb, hlawv thiab ua pob.

(3) Tshawb xyuas cov ntawv xov xwm tseem ceeb ntawm crankshaft thiab txuas cov ntawv xov xwm, thiab kho lawv raws li qib kho tom qab qhov loj tshaj qhov txwv. Kev kho crankshaft phau ntawv journal yog raws li nram no:

(4) Txheeb xyuas qhov yuav tsum tau ua kom tawv tawv ntawm crankshaft cov ntawv xov xwm thiab cov ntaub ntawv txuas txuas, thiab lawv yuav tsum ua kom tau raws li cov kev cai. Txwv tsis pub, nws yuav tsum tau rov ua dua kom tau raws li cov kev cai siv.

(5) Lub radial runout ntawm lub crankshaft thiab radial runout ntawm lub ntsej muag thrust mus rau cov axis ntawm lub ntsiab phau ntawv xov xwm yuav tsum tau raws li cov kev cai. Txwv tsis pub, nws yuav tsum raug kho.

(6) Lub parallelism ntawm cov ntawv xov xwm txuas txuas mus rau cov axis ntawm cov ntawv xov xwm tseem ceeb yuav tsum ua raws li cov kev cai.

(7) Thaum lub hauv ntej thiab nram qab kis tau tus mob gears ntawm lub crankshaft yog tawg, puas los yog hnav hnyav, lub crankshaft yuav tsum tau hloov.

(8) Yog hais tias lub crankshaft tshuav nyiaj li cas bolt yog tawg, nws yuav tsum tau hloov. Tom qab lub crankshaft hloov qhov sib npaug ntawm qhov hnyav lossis qhov sib npaug ntawm qhov hnyav, nws yog lub sijhawm los ua qhov ntsuas qhov sib npaug ntawm lub crankshaft los ua kom ntseeg tau tias qhov nyiaj tsis sib npaug raws li cov kev xav tau. Hnav-resistant electrode

(9) Yog hais tias lub flywheel thiab pulley bolts tau tawg, khawb lossis qhov txuas ntxiv tshaj qhov txwv, hloov lawv.

(10) Ua tib zoo tshuaj xyuas lub shock absorber ntawm lub crankcase ko taw. Yog tias nws puas lawm, roj hmab yog kev laus, tawg, deformed los yog tawg, nws yuav tsum tau hloov.

(11) Thaum sib dhos lub crankshaft, xyuam xim rau lub installation ntawm lub ntsiab bearing thiab thrust bearing. Xyuas lub crankshaft axial clearance thiab ceev lub ntsiab bearing cap ntsug bolts thiab kab rov tav bolts raws li xav tau.
