1. Iimfuno zeebheringi ezichanekileyo kwiindawo ezihambelanayo

Ekubeni ukuchaneka kokuchaneka kokuchaneka ngokwayo kungaphakathi kwe-1 μm, kuyimfuneko ukuba ibe nokuchaneka komgangatho ophezulu kunye nokuchaneka kobume kunye neengxenye zayo ezihambelanayo (i-shaft, isihlalo esiphetheyo, isigqubuthelo sokugqibela, indandatho yokugcina, njl.), ngokukodwa ukuchaneka kokubambisana. Umphezulu kufuneka ulawulwe kwinqanaba elifanayo lokuthwala Oku kubalulekile kwaye kulula kakhulu ukungahoywa.

Kufuneka kwakhona kuqatshelwe ukuba ukuba iindawo ezihambelanayo zebheringi echanekileyo azifikeleli ezi mfuno zingentla, ukuchaneka okuchanekileyo kuya kuhlala kunempazamo ngokuphindwe kaninzi kunokuqala emva kokufakwa, okanye nangaphezulu kwe-10 impazamo, kwaye ayisiyonto ichanekileyo kwaphela.Isizathu kukuba umatshini ohambelanayo Impazamo yamacandelo ayisoloko ibekwe phezulu kwimpazamo yokuthwala, kodwa yongezwa emva kokunyuswa ngokuphindaphinda okuhlukeneyo.

2. Ukufakwa kweebheringi ezichanekileyo

Ukuqinisekisa ukuba ukuthwala akuvelisi deformation egqithisileyo emva kofakelo, kufuneka yenziwe:

(1) Ukujikeleza kwe-shaft kunye nomngxuma wesihlalo kunye nokuma kwegxalaba kufuneka kufuneke ngokuchaneka okuhambelanayo kwebheringi.

(2) Kuyimfuneko ukubala ngokuchanekileyo ukuphazanyiswa kwe-ferrule ejikelezayo kunye nokulungelelaniswa okufanelekileyo kwe-ferrule esisigxina.

Ukuphazamiseka kwe-ferrule ejikelezayo kufuneka ibe yincinci kangangoko kunokwenzeka.Ngethuba nje impembelelo yokwandiswa kwe-thermal kwiqondo lokushisa lokusebenza kunye nefuthe lamandla e-centrifugal kwisantya esiphezulu liqinisekisiwe, ayiyi kubangela ukukhahlela okanye ukutyibilika komgangatho oqinileyo.Ngokobungakanani bomthwalo osebenzayo kunye nobukhulu bokuthwala, i-ring fixed ikhetha i-clean clearance encinci okanye i-interference fit.Ukukhululeka kakhulu okanye ukuqina kakhulu akuncedi ukugcina imilo yokuqala kunye nechanekileyo.

(3) Ukuba ibherethi isebenza phantsi kweemeko zesantya esiphezulu kwaye ubushushu bokusebenza buphezulu, kufuneka kuqwalaselwe ingqalelo ekhethekileyo kwindandatho ejikelezayo engakhululekanga kakhulu ukuthintela ukungcangcazela kwe-eccentric, kunye nokufaneleka kweringi esisigxina ukuthintela izikhewu. ukwenzeka.Ikhubaza phantsi komthwalo kwaye ivuselele ukungcangcazela.

(4) Umqathango wokwamkela ukungenelela okuncinci kwindandatho esisigxina kukuba amacala omabini omgangatho ohambelanayo anobume obuchanekileyo obuchanekileyo kunye noburhabaxa obuncinci, kungenjalo kuya kwenza ukufakela kube nzima kunye nokuqhaqha.Ukongezelela, impembelelo ye-thermal elongation ye-spindle kufuneka ithathelwe ingqalelo.

5Ukuba uphazamiseko olufanelekileyo lukhulu kakhulu, i-axial preload yangaphakathi iya kuba nkulu kakhulu, ibangele iziphumo ezibi.I-shaft ephambili esebenzisa i-double-row short short cylindrical roller bearings kunye ne-shaft ephambili yeebheringi ezijikelezayo zinemithwalo emikhulu, ngoko ke ukuphazamiseka okufanelekileyo kuninzi kakhulu.

3. Iindlela zokuphucula ukuchaneka okukuko

Ukuze kuphuculwe ukuchaneka kwangempela kokuchaneka kofakelo lokuzala, kuyimfuneko ukusebenzisa iindlela zokulinganisa kunye nezixhobo zokulinganisa ezingaphambanisi ukuthwala ukuphumeza umlinganiselo ochanekileyo wemilinganiselo yomgangatho ohambelana nomngxuma ongaphakathi kunye nesangqa sangaphandle sokuthwala, kunye nomlinganiselo we-diameter yangaphakathi kunye nedayimitha yangaphandle inokuqhutywa Zonke izinto zilinganiswa, kwaye idatha elinganisiweyo ihlalutywa ngokucokisekileyo, ngokusekelwe apho, imilinganiselo yeendawo zokufakela ezithwele i-shaft kunye nomngxuma wokuhlala zihambelana ngokuchanekileyo.Xa ngokwenene ukulinganisa imilinganiselo ehambelanayo kunye nemilo yejometri ye-shaft kunye nomngxuma wesihlalo, kufuneka iqhutywe phantsi kweemeko zokushisa ezifanayo xa kulinganisa ukuthwala.

Ukuze kuqinisekiswe umphumo ophezulu ohambelanayo, uburhabaxa be-shaft kunye nomngxuma wezindlu ohambelana nomgangatho wokuthwala kufuneka ube mncinci kangangoko.

Xa usenza le milinganiselo ingentla, iiseti ezimbini zamanqaku anokubonisa isalathiso sokutenxa okuphezulu kufuneka zenziwe kwisangqa sangaphandle kunye nomngxuma ongaphakathi wokuthwala, kunye neendawo ezihambelanayo ze-shaft kunye nomngxuma wokuhlala, kumacala omabini vala. kwi-chamfer yendibano, ukwenzela ukuba kwindibano yangempela, ukutenxa okukhulu kwamaqela amabini ahambelanayo kulungelelaniswa kwicala elifanayo, ukwenzela ukuba emva kwendibano, ukuphambuka kwamaqela amabini kunokutshatyalaliswa ngokuyinxenye.

Injongo yokwenza iiseti ezimbini zamanqaku okuqhelaniswa kukuba imbuyekezo yokutenxa inokuqwalaselwa ngokubanzi, ukwenzela ukuba ukuchaneka okujikelezayo okufanelekileyo kweziphelo zombini zenkxaso kuphuculwe, kunye nempazamo ye-coaxiality yomngxuma wesihlalo phakathi kwezixhaso ezimbini kunye ne-coaxiality ye-coaxiality yembobo yokuhlala iijenali zeshaft kuzo zombini iziphelo zifunyenwe ngokuyinxenye.phelisa.Ukuphumeza amanyathelo okomeleza umphezulu kumphezulu wokukhwelana, okufana nokuqhunyiswa kwesanti, ukusebenzisa iplagi echanekileyo enedayamitha engaphezulu kancinane ukuplaga umngxuma ongaphakathi kube kanye, njl. njl., kuyanceda ekuphuculeni ukuchaneka kokukhwelana.
