1. Ukulungiswa kokususwa komphezulu wamazinyo okwandisiweyo

Ukunyuka kwe-clean kaninzi kubangelwa ukunyuka kwe-clean phakathi kwe-shaft kunye ne-sleeve hole, ngoko ke ukukhutshwa kufuneka kubuyiselwe emva kokulungiswa kwe-shaft kunye nomkhono. Ukuba ukunxiba kombhobho wempompo akunzulu, i-alloy ethwele inokudityaniswa kwi-tooth top, ize iguqulwe ngokweemfuno zomfaneleko. Ukuba umbhobho wempompo unxitywe kakhulu, indlela ye-sleeve yamkelwe ukulungiswa. Indlela yile: ukubhonqa udonga lombhobho wempompo, kunye nokuguqula i-semicircular bushing kunye nobukhulu be-3 ukuya kwi-4 mm ngokobukhulu bombhobho wempompo ngentsimbi okanye ubhedu. Emva kokuba umkhono wehlisiwe kwimpompo yempompo, ibotshwe nge-clamp, kwaye emva koko idityaniswe kunye nobubanzi be-bushing kuzo zombini iziphelo, kwaye ipholile ngokukhawuleza kwibhokisi yesanti emva kwe-welding. Ekugqibeleni, i-cavity yempompo ibhokile kubungakanani obuqhelekileyo, kwaye i-taper yayo kunye ne-ovality ayikho ngaphezu kwe-0.02 mm. I-bushing inokudibaniswa ne-epoxy resin glue.

2. Ukulungiswa kokunyuswa kokukhutshwa kwe-meshing gear

Ukukhutshwa kwecala lezinyo kunempembelelo encinci ekusebenzeni kwempompo yeoli, ngoko ixabiso elivumelekileyo likhulu, ngamanye amaxesha ukuya kuthi ga kwi-1 mm, ngoko kukho ukulungiswa okumbalwa. Ukuba indawo yezinyo legiya ayigudi okanye ineentsimbi emva kokugqoka, yipolishe ngelitye leoli. Ekubeni amazinyo ompompo agqitywe kwicala elinye, i-gear inokuguqulwa kwaye isetyenziswe xa ukugqithiswa kwamazinyo akudluli ixabiso elivumelekileyo; ukuba idlula ixabiso elivumelekileyo, kufuneka itshintshwe okanye ilungiswe.

3. Ukulungiswa konyuso lwesiphelo sobuso

Ukupheliswa kobuso bokugqibela kunempembelelo enkulu kwiimpawu zokusebenza zempompo yeoli (uxinzelelo lweoli, umthamo weoli). Ukuba ukucocwa kobuso besiphelo kudlula umgangatho, kufuneka kulungiswe. Amanyathelo okulungisa ami ngolu hlobo lulandelayo:

(1) Ukuba umzantsi wegumbi lokumpompa ugugile, ukupolishwa kufuneka kusetyenziswe ukuphelisa izibonda kumphezulu onxityiweyo.

(2) Ukuba isiphelo sesixhobo sobuso kunye nesigqubuthelo sempompo sigugile, ukuba ukunxiba akunabungozi, umphezulu unokugqunywa ngentlabathi erhabaxa kunye nomhlaba kwiqonga (okanye iglasi) ukuphelisa ukunxiba kunye nokungalingani; ukuba ukunxiba kunzulu kwaye ukuphela kobuso bokucoca kukhulu, kunokulungiswa ngokugaya okanye ukuguqula kuqala kwaye emva koko ukugaya.

Xa kusila, ukuphakama kobuso besiphelo sesixhobo esingaphantsi kobuso besiphelo sendlu (oko kukuthi, ukucocwa kokuphela kwezinyo) kufuneka kujongwe rhoqo ngegeyiji yobunzulu okanye i-micrometer. Emva kokusila, umzimba wempompo kufuneka ube ne-mating surface perpendicular kumgca ophakathi we-shaft hole. I-non-perpendicularity (okanye ukuphambuka) ngokuqhelekileyo ayikho ngaphezu kwe-0.1 mm nge-100 mm, kwaye ukungalingani kwendawo yokukhwelana ngokubanzi akukho ngaphezu kwe-0.02 mm.

4. Ukulungiswa kokunyuka kwemvume phakathi kwe-oil pump shaft kunye nokuthwala

Njengoko ukucocwa phakathi kwe-shaft kunye ne-bearing kunyuka, i-meshing yesiqhelo ye-gear pair iya kutshatyalaliswa, kwaye i-tooth top iya kuxubha kwi-cavity yepompo, ukutshabalalisa ubudlelwane obuhambelanayo becandelo ngalinye kunye nokunciphisa ukunikezelwa kweoli. Xa ukucocwa phakathi kwe-shaft yokuqhuba kunye ne-bearing kukhulu kakhulu, indlela yokulungisa ubungakanani ingasetyenziselwa ukulungiswa, umngxuma we-shaft unokwandiswa (unokunyuswa ngu-0.25 mm, 0.50 mm), kwaye i-shaft yokuqhuba inokugqithwa ngokufanelekileyo. (intsimbi yentsimbi okanye i-chrome plating), okanye inokulungiswa ngendlela ye-sleeve (ubukhulu bemikhono bumalunga ne-15 mm), kunye nokugxila kwemikhono ephezulu nangaphantsi. kufuneka kuqinisekiswe ngexesha lokubuyisela kwakhona. Ngenxa yesi sizathu, kwiimpompo zeoyile ezinemikhono yokuthwala kwikhava yempompo, kungcono ukufaka isigqubuthelo sempompo kumzimba wempompo kwaye ugqibezele ukucubungula ngexesha elinye. I-taper kunye ne-ovality yomngxuma wokuthwala akufanele idlule i-0.02 mm. Emva kokulungiswa, ukungahambi ngokuthe ngqo kwe-shaft akufanele kudlule i-0.05 mm ngaphezu kobude bonke. Xa ukucocwa phakathi kwe-shaft gear kunye nomngxuma we-shaft mkhulu kakhulu, le ndlela ingentla ingasetyenziselwa ukulungiswa. Kwimeko yokunxiba okuncinci, ekubeni i-shaft ye-passive gear ayishukumi, ukunxiba kwayo kukunxitywa kwelinye icala, ngoko ke i-shaft inokucinezelwa kwaye ijike i-180 ° kwaye icinezelwe ukuze isetyenziswe (ngeli xesha, ukuba ukuphazamiseka kwe-static fit kuyancitshiswa. , inokulungiswa nge-electroplating). Emva kokuba i-shaft icinezelwe kumzimba wempompo, intloko ye-shaft kufuneka idibanise kwindawo edibeneyo yezindlu nge-0.05-0.50 mm. Emva kokuba umngxuma we-shaft kwi-passive gear igugile, ilungiswa ngendlela ye-sleeve. Emva kokulungiswa, imbobo yeoli yokuthambisa kufuneka iqhutywe ngokweemfuno zokuqala.

5. Ukulungiswa kokunyuka kwe-axial clearance ye-shaft esebenzayo

Xa le mvume idlula ixabiso elivumelekileyo, lihlengahlengiswa ngokunyuka okanye ukongeza i-gasket ekupheleni kwendlu yempompo. Ngexesha lokulungiswa, kufuneka kuqinisekiswe ukuba le mvume ayinkulu kunokukhutshwa kwezinyo.
