Indlela yokulinganisa ukuthwala i-axial clearance

Indlela yokulinganisa ukuthwala i-axial clearance
Xa ukhetha ukukhupha imvume, le miba ilandelayo kufuneka iqwalaselwe:
1. Iimeko zokusebenza zokuthwala, njengomthwalo, ubushushu, isantya, njl.;
2. Iimfuno zentsebenzo yokuthwala (ukuchaneka kokujikeleza, i-torque ye-friction, i-vibration, ingxolo);
3. Xa i-bearing kunye ne-shaft kunye nomngxuma wezindlu kwi-interference fit, i-bearing clearance iyancipha;
4. Xa i-bearing isebenza, umehluko weqondo lokushisa phakathi kwamakhonkco angaphakathi nangaphandle uya kunciphisa ukukhutshwa kwempahla;
5. Ukunciphisa okanye ukunyuka kwe-bearing clearance ngenxa yee-coefficients ezahlukeneyo zokwandiswa kwe-shaft kunye nezixhobo zezindlu.
Ngokutsho kwamava, eyona mvume yokusebenza ifanelekileyo yeebheringi zebhola isondele kwi-zero;iibheringi ze-roller kufuneka zigcine isixa esincinci semvume yokusebenza.Kumacandelo afuna ukuqina kwenkxaso elungileyo, iibheringi ze-FAG zivumela inani elithile lokulayisha kwangaphambili.Kucaciswe ngokukodwa apha ukuba into ebizwa ngokuba yi-clean clearance ibhekisela ekukhutshweni kwe-bearing phantsi kweemeko zangempela zokusebenza.Kukwakho nolunye uhlobo lococeko olubizwa ngokuba yi-original clearance, olubhekiselele kucoceko ngaphambi kokuba kufakwe ukuthwala.Ukukhutshwa kokuqala kukhulu kunokukhutshwa okufakiweyo.Ukhetho lwethu lwemvume ikakhulu kukukhetha imvume yokusebenza efanelekileyo.
Amaxabiso ococeko achazwe kumgangatho wesizwe ahlulwe abe ngamaqela amathathu: iqela elisisiseko (iqela 0), iqela elincedisayo elinemvume encinci (iqela 1, 2) kunye neqela elincedisayo elinemvume enkulu (iqela 3, 4, 5).Xa ukhetha, phantsi 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 elincedisayo lokucoca lifanelekile ukulungelelaniswa kokuphazamiseka phakathi kokuthwala kunye ne-shaft kunye nomngxuma wezindlu.Umahluko weqondo lokushisa phakathi kwamakhonkco angaphakathi nangaphandle okuthwala mkhulu.I-deep groove ball bearing idinga ukuthwala umthwalo omkhulu we-axial okanye idinga ukuphucula ukusebenza kokulungelelanisa.Ukunciphisa i-torque ye-friction yeebheringi ze-NSK kunye nezinye iziganeko;iqela elincedisayo lokucoceka elincinane lifanelekile kwizihlandlo ezifuna ukuchaneka kokujikeleza okuphezulu, ukulawula ngokungqongqo ukufuduka kwe-axial yomngxuma wezindlu, kunye nokunciphisa ukungcangcazela kunye nengxolo.1 Ukulungisa ukuthwala
Emva kokumisela uhlobo kunye nomzekelo wokuthwala, kuyimfuneko ukuyila ngokuchanekileyo isakhiwo esidibeneyo somgca we-rolling ukuqinisekisa ukusebenza okuqhelekileyo kwe-TIMKEN.
Uyilo oludityanisiweyo lwesakhiwo sokuthwala lubandakanya:
1) Isakhiwo sokuphela kwenkxaso ye-Shafting;
2) Intsebenziswano yeebheringi kunye neenxalenye ezinxulumeneyo;
3) Ukuthambisa kunye nokutywinwa kweebheringi;
4) Ukuphucula ukuqina kwenkqubo yokuthwala
1. Ukulungiswa kuzo zombini iziphelo (indlela enye igxininiswe kuzo zombini iziphelo) Kwiishafu ezimfutshane (i-span L<400mm) phantsi kobushushu obuqhelekileyo bokusebenza, i-fulcrum isoloko ilungiswa ngendlela enye kuzo zombini iziphelo, kwaye nganye ithwala ithwala i-axial force kwelinye. ulwalathiso.Njengoko kuboniswe kumzobo, ukwenzela ukuba kuvumeleke ukunyusa okuncinci kwe-thermal ye-shaft ngexesha lokusebenza, ukuthwala kufuneka kufakwe kunye ne-axial clearance ye-0.25mm-0.4mm (ukukhutshwa kuncinci kakhulu, kwaye akuyimfuneko ukuba yizobe kumzobo wesakhiwo).
Iimpawu: Nciphisa intshukumo ye-bidirectional ye-axis.Ifanelekile kwiishafu ezinotshintsho oluncinci kwiqondo lokushisa lokusebenza.Qaphela: Uthathela ingqalelo ubude be-thermal, shiya isithuba sembuyekezo c phakathi kwesigqubuthelo esithwalayo kunye nobuso besiphelo sangaphandle, c=0.2~0.3mm.2. Isiphelo esinye sigxininiswe kumacala omabini kwaye enye isiphelo siyaqubha.Xa i-shaft ide okanye ukushisa okusebenzayo kuphezulu, ukwandiswa kwe-thermal kunye nokunciphisa i-shaft kukhulu.
Isiphelo esisisigxina sixhomekeke kumandla e-axial ye-bidirectional ngeqela elilodwa okanye iqela elithweleyo, ngelixa isiphelo samahhala siqinisekisa ukuba i-shaft inokubhukuda ngokukhululekile xa isanda kunye nezivumelwano.Ukuze ugweme ukukhulula, i-ring yangaphakathi yebherethi edadayo kufuneka ilungiswe nge-axially kunye ne-shaft (i-circlip isoloko isetyenziswa).Iimpawu: Enye ifulcrum imiliselwe kumacala omabini, kwaye enye ifulcrum ihamba ngeaxially.I-deep groove ball bearing isetyenziswa njenge fulcrum edadayo, kwaye kukho umsantsa phakathi kweringi yangaphandle yebheringi kunye nesigqubuthelo sokugqibela.Iibheringi ze-Cylindrical roller zisetyenziswa njenge-fulcrum edadayo, kwaye i-ring yangaphandle ye-bearing kufuneka ilungiswe kumacala omabini.
Iyasebenza: I-axis ende kunye nokutshintsha okukhulu kobushushu.
