Kev daws teeb meem ntawm Mechanical Devices hauv Microscopes
Cov kev ua txhaum tseem ceeb ntawm lub tshuab tsom iav tsom iav yog qhov tsis siv neeg swb los yog tsis sib xws nruj thaum nqa thiab txo qis. Tsis siv neeg swb yog hais txog qhov tshwm sim uas lub raj, caj npab lossis theem maj mam nqis los ntawm nws tus kheej qhov hnyav yam tsis muaj kev hloov kho thaum nws nyob ruaj khov ntawm qee txoj haujlwm. Qhov kev ua txhaum no tshwm sim vim lub zog gravitational ntawm lub raj, caj npab lossis theem siab tshaj qhov kev sib txhuam zoo li qub. The solution is to increase the static friction force so that it exceeds the weight of the tube or arm.
Rau qhov ntxhib tsom mechanisms ntawm inclined-tube microscopes thiab feem ntau binocular microscopes, yog hais tias caj npab plam cia, tuav lub log los tiv thaiv plam nyob rau sab hauv ntawm ntxhib tsom pob qhov rooj nrog ob txhais tes, thiab ceev lawv clockwise tib lub sij hawm kom tsis txhob ntog. Yog tias txoj kev no tsis ua haujlwm, cov neeg ua haujlwm tu neeg ua haujlwm yuav tsum tau hu rau kev kho.
Tsis siv neeg plam ntawm lub tshuab tsom iav raj feem ntau ua rau kev nkag siab yuam kev tias lub meshing ntawm lub iav thiab khib yog xoob heev. Qee tus neeg yuav ntxiv shims hauv qab khib raws li. Txawm hais tias qhov no tuaj yeem tso tseg ib ntus lub raj los ntawm kev swb, nws tso cov iav thiab khib rau hauv qhov txawv txav meshing. Kev txav mus tas li yuav ua rau deformation ntawm ob lub iav thiab khib. Tsis sib xws shimming, tshwj xeeb, aggravates khib deformation, ua rau tsis sib xws meshing: nruj nyob rau hauv ib co seem thiab xoob nyob rau hauv lwm tus neeg. Yog li ntawd, txoj kev no tsis pom zoo.
Tsis tas li ntawd, yog hais tias lub ntxhib focusing mechanism tsis tau khaws cia rau lub sij hawm ntev thiab lub lubricating roj tau qhuav, tsis xis nyob los yog txawm kev sib txhuam suab nrov ntawm cov neeg kho tshuab qhov chaw yuav tshwm sim thaum lub sij hawm nqa. Nyob rau hauv tas li ntawd, lub mechanical assembly yuav disassembled, ntxuav, greased thiab reassembled.
