Olona caciso lweukuthwala imotoemsebenzini unxulumene nomthwalo wokuthwala, isantya, ukuthambisa, ukunyuka kwamaqondo obushushu, ukungcangcazela, ukwakheka koyilo kunye noburhabaxa bomphezulu betafile ehambelanayo.Xa ukhetha, kufuneka kukhethwe ngokwemeko ethile.Ukucocwa emva kokunciphisa ukwandiswa okanye ukuchithwa kwendandatho ngenxa yokuphazamiseka okufanelekileyo xa ukuthwala kufakwe kwi-shaft okanye kwizindlu kubizwa ngokuba "i-installation clearance" kwi-clean ye-theory.Ukukhutshwa okufunyenweyo ngokudibanisa kunye nokukhupha ukuhluka kwe-dimensional ngenxa yokuhluka kweqondo lokushisa ngaphakathi kwebherethi ukusuka kwindawo yokunyuka ebizwa ngokuba "i-effective clearance".Ukukhutshwa xa ukuthwala kufakwe kumatshini phantsi komthwalo othile kunye nokujikeleza, oko kukuthi, ukuhlanjululwa emva kokukhutshwa okusebenzayo kunye nokuguqulwa kwe-elastic okubangelwa ngumthwalo wokuthwala kubizwa ngokuba "imvume yokusebenza".
Njengoko kubonisiwe kumzobo, xa imvume yokusebenza ingalunganga kancinane, ubomi bokudinwa kokuthwala bubude kakhulu, kodwa ubomi bokudinwa buyancipha kakhulu ngokunyuka kwemvume engalunganga.Ke ngoko, xa ukhetha ukukhutshwa kokukhutshwa, kuyacetyiswa ngokubanzi ukuba wenze i-zero yokusebenza ibe ngu-zero okanye ilungile kancinci.Xa ukhetha ukuthwala imvume, le miba ilandelayo kufuneka ithathelwe ingqalelo: 1. Iimeko zokusebenza zokuthwala, njengomthwalo, ukushisa, isantya, ukungcangcazela, njl.;2. Iimfuno zokusebenza kwebheringi (ukuchaneka kokujikeleza, i-torque ye-friction, i-vibration, ingxolo);3. Xa i-bearing, i-shaft kunye nengxuma yezindlu ikwi-interference fit, i-bearing clearance iyancipha;4. Xa i-bearing isebenza, ukuhluka kweqondo lokushisa phakathi kwamakhonkco angaphakathi nangaphandle kubangela ukuba i-bearing clearance iyancipha;5. Ngenxa yokwandiswa kwee-coefficients ezahlukeneyo ze-shaft kunye nezinto zezindlu , okubangela ukuba i-bearing clearance iyancipha okanye inyuke.
Ngokwamava, imvume yokusebenza efanelekileyo kakhulu kwiibhola zebhola isondele kwi-zero, kwaye inani elincinci lokukhutshwa komsebenzi kufuneka ligcinwe kwiibheringi ze-roller.Kumacandelo afuna ukuqina kwenkxaso efanelekileyo, ukuthwala kuvunyelwe ukuba nomlinganiselo othile wokulayisha kwangaphambili.Ngaphantsi kweemeko eziqhelekileyo zokusebenza, iqela elisisiseko kufuneka likhethwe, ukwenzela ukuba ukuthwala kunokufumana imvume yokusebenza efanelekileyo.Xa iqela elisisiseko lingenako ukuhlangabezana neemfuno zokusetyenziswa, ukukhutshwa kweqela elincedisayo kufuneka kukhethwe.Iqela elikhulu lokuncedisa ukuhlanjululwa lilungele ukungenelela kokuphazamiseka phakathi kwe-bearing kunye ne-shaft kunye nezindlu zezindlu.Iqela elincedisayo lokucoceka elincinci lifanelekile kwizihlandlo ezifuna ukuchaneka kokujikeleza okuphezulu, ulawulo olungqongqo lwe-axial displacement yomgodi wezindlu, kunye nokunciphisa ukungcangcazela kunye nengxolo.Ukongezelela, xa ukuqina kokuthwala kufuneka kuphuculwe okanye ingxolo ifuna ukuncitshiswa, imvume yokusebenza kufuneka ithathe elinye ixabiso elibi, kwaye xa izinga lokushisa liphakama ngokukhawuleza, ukukhutshwa komsebenzi kufuneka kuthathe ixabiso elingakumbi, njl. ., kwaye uhlalutyo oluthile kufuneka lwenziwe ngokwemiqathango yokusebenza..
Ekubeni imvume yokusebenza ihambelana ngokusondeleyo nobomi, ukunyuka kweqondo lokushisa, ukungcangcazela kunye nengxolo yokuthwala, ukulawulwa kokukhutshwa kwangaphakathi kokuthwala kubaluleke kakhulu.Iinqwelo zeemoto kufuneka zibe nemvume yangaphakathi efanelekileyo yokugcina ukusebenza kakuhle.Ukucocwa kwasekuqaleni kokuthwala sisalathisi esibaluleke kakhulu.Ngoko ke, ngaphambi kokuba ukuthwala kuhlanganiswe, i-gauge ye-feeler kufuneka isetyenziswe ukujonga imvume yokuqala, kwaye ngexesha elifanayo, ukuchasana koqhagamshelwano phakathi kwendandatho yangaphakathi kunye ne-armature shaft kufuneka kulinganiswe ukuqinisekisa ukudibanisa kwayo okuthembekileyo.Emva kokuba i-motor idityanisiwe, ukunyanzeliswa kokukhutshwa kukucoceka okuhambelanayo.Ukuba ukucocwa kuncinci ngeli xesha, kuya kubangela ukuba ukuthwala kugqithise, kubangele ukuba indandatho yangaphakathi ikhulise, yenza ukuba i-clean incinci kwaye incinci, kwaye ekugqibeleni ibangele ukuvutha;Ukuba ikhulu kakhulu, i-roller iya kugxininiswa ngokungafaniyo, okubangela ukunyakaza okongeziweyo, okulula ukulimaza ukuthwala.Ngoko ke, emva kwendibano epheleleyo yemoto, i-gauge ye-feeler kufuneka isetyenziswe ukulinganisa ukucocwa kwe-bearing emva kwendibano.Ukuba ukucocwa kufunyenwe kungafanelekanga, kufuneka kuchithwa kwaye kulungiswe.I-original clearance clearance yeebheringi zeZWZ zonke zihambelana ne-GB4604.Amaxabiso e-radial clearance asebenza kwiibheringi ezinganyuswanga kunye nezothulwayo.Iibheringi ezinkulu okanye ezincinci kunexabiso eliqhelekileyo lococeko nazo zinokuveliswa ngokweemfuno zomsebenzisi.
