Iibheringi: ngobukhulu eqhelekileyo. ubukhulu Standard of iibheringi

Kuyinto negalelo indibano eyodwa yinxalenye shaft inkxaso axhasayo kunye kokutshintsha okanye onenombolo yokugqibela ngaphandle zochuku ilahleko amandla. Kukho iintlobo ezininzi amasebe. Kulo mzekelo, ubungakanani iibheringi kwiimeko ezininzi kulawulwa yi GOST.

uhlobo

Yindawo olu hlobo zisetyenziswa kushishino kunye namanye amacandelo ezoqoqosho zilangazelelwa kakhulu. Kukho hydrostatic, igesi-emile, iibheringi owahluke ngokwemvelo, kunye namanye amaqela. Noko ke, iintlobo zixhaphakileyo le amaqhina iziliphu kaloliwe. Ngokutsho umthwalo waqonda zombini ezi maqela zihlukaniswe:

• ziqu;

• ukumelana;

• contact emboxo.

iibheringi agiqekayo

Imiba ephambili yolu hlobo nodes zeebhola okanye izileyi zisendaweni kumgama othile enye kwenye kumnini okhethekileyo, ebizwa umahluli. Kule nkqubo, balisuse yakwenza obuqinileyo naabo ababathandayo ngenxa amakhonkco abe mabini, elinye nokuthe kwiimeko kakhulu static. Yindawo olu hlobo zisetyenziswa kushishino kakhulu. Inyaniso kukuba xa kuthelekiswa iibheringi ngaphakathi, ukuba babe eziliqela iingenelo. Kwabo ziquka ukukhuhlana eliphantsi ikakhulu nokuselwa encinane igrisi. Lula ukusetyenziswa kunye nofakelo - oku kwakhona ukuba yintoni umahluko phakathi iibheringi ezinjalo. Standards (GOST olawula ubungakanani) leeyunithi ezilolo thaca kule theyibhile ezizodwa. Ngoko ke, ukuze bafumane efanelekileyo kwimeko ethile, ebizwa ukwenza umgudu omkhulu. Node yale hlobo uyakwazi ukukhetha ngenene naliphi design uhlobo.

Ubuntununtunu bokuba lokungcangcazela nokothuka - i ethile kuphela, ezahluke iibheringi ezinjalo. Standards kwimveliso yabo kufuneka kunyanzeleka ukuba ilandelwe. Kungenjalo abayi kuhlala ixesha elide kakhulu.

Types of iibheringi kwabadlali

Ukongeza ntshikilelo olu hlobo nodes zihlelwa ngokwamaqela ngokwezi khrayitheriya zilandelayo:

• Waxonxa izinto r. Kule nkalo, ukwahlula ibhola kunye roller iibheringi. Thaca izinto ngoxa uhlobo wokugqibela inokuba etsobhileyo, zezindlu, yenaliti-emile, ephothiweyo, umphanda emile, njalo njalo. D.

• Ngokutsho samoustanovleniya ubuchule. Kulo mzekelo, bahlule phakathi iibheringi ungqukuva kunye nesamoustanavlivayuschiesya.

• Ngokutsho inani lweziqalelo kwabadlali. Kukho iibheringi kumqolo omnye kunye kabini.

• In ubukhulu. Zonke neyenzelwa ukuba umhla ibhekiselele koku siseko bohlulwa series eziliqela.

Kuxhomekeka series kwi sangqa enye yangaphakathi, ububanzi lokuzala kunye D sayo ungahluka. iibheringi Used ke indibano iimoto, iibhayisekile, omoyo njalo njalo. D.

zobukhulu

Amacala olu hlobo node sichaza GOST 3478-79. Xa yanelisekile ukuba zifunyenwe iibheringi enamandla kakhulu ixesha elide. Le migangatho isebenza kuzo zonke iintlobo lweendibano roller, ngaphandle imifuziselo ngenjongo ekhethekileyo, ne design okhethekileyo. Kwimeko yokugqibela, amacandelo sinokwenziwa iindidi zobungakanani, eyona ifanelekileyo ukuba uyilo ethile.

Qwalasela iibheringi standard ubungakanani series ngamnye, njengokuba sele kukhankanyiwe, kumacwecwe ezizodwa abonisa ngobubanzi komphakathi nomphandle wocango, ubukhulu bobungakanani incinane (Rmin), yaye ububanzi obungu emakhonkcweni yangaphakathi langaphandle (B). Ngokomzekelo, sikunika netafile thotho ethwele ngobubanzi 8 (olufinyeziweyo).

Okunye izintlu ezineenkcukacha zingafumaneka kule ncwadi ezikhethekileyo. Kukho kwakhona nemigangatho iibheringi Compass - umhleli indlela yemizobo, eyenzelwe ukuba uyilo-ancedwa kwikhompyutha (uyilo kwithala leencwadi). Kukho iitafile ngenxa ngobubanzi ezahlukeneyo ezalathelwe uphuhliso.

iiklasi ukuchana

ubukhulu Standard asenokuvela iibheringi, ukuze ukwazi ukufunda iitafile ezizodwa. Noko ke, kwezinye iimeko, ukuba ezinye izinto ezinxaxhileyo kwi imilinganiselo GOST. iibheringi iklasi Ukuchaneka zihlukaniswe:

• obuqhelekileyo "0";

• "6" okuchaneka phezulu;

• eliphezulu "5";

• osobovysokoy "4";

• ultra-high "2".

Nodes izakhiwo ezahlukeneyo, kunokuba nokumelana kakuhle echazwe. Ngoko ke, umzekelo, imigangatho sisichazela ibhayisekile (608 uhlobo) zezi:

• iibhola ukunyamezelana - 0 / -0.005;

• track engaphakathi - + 0.0001 / -0.0003;

• uhlanga engaphandle - + 0.0001 / -0.0005.

abizwa

Lothuli iibheringi nemigangatho yezandla zabo zithotyelwe enyanzelekileyo. Ukuze abathengi babone ukuba uhlobo kwiqhina phambi kwakhe, yaye yintoni injongo kunokwenzeka ukuba ukusebenzisa ekhethekileyo yokumakisha isicelo. iibheringi Designated ngokuqhelekileyo eqingqiweyo isethi amanani. Ngamanye amaxesha zokuphawula standard ziquka zombini iileta. Kulo mzekelo:

• Inani lokuqala okanye unobumba zibonisa uhlobo lokuphatha.

• Amanani amabini elandelayo amisele umkhosi manqaku. Iqela lokuqala ibonisa ububanzi okanye ukuphakama, le yesibini - le ubukhulu.

• Amanani amabini okugqibela bamele sangqa ikhowudi lokuvula. Ukuba uphinda-phinde ngo-5, singakwazi ukufumana ubukhulu d mm.

ubukhulu Umgangatho iibheringi 66 414 (kule meko kutyalwe ikhethiwe ngokuhambelana GOST 3325-85), umzekelo, ngolu hlobo lulandelayo:

• d - 70 mm;

• D - 180 mm;

• ububanzi - 42 mm;

• ubunzima - 5,74 kg.

iibheringi Plain

Units yale hlobo luqulathe izinto ezimbini ezingundoqo: a nqanawa igobhogobho naphakathi izeziphi izinto zokuthambisa ezikhethekileyo. Izinto eziluncedo eziphambili zezi iibheringi ezi ngobubanzi wayeyixhalabele ezincinane, kwakunye nokukwazi ukwenza kubo kwaye usebenzise shaft detachable design inzima kakhulu. Bobubi iindawo ezi zilwanyana zithathwa ukuba Musani kakhulu ubomi inkonzo ende kunye nemfuneko zokuthambisa imali eninzi.

Types of iibheringi isilayidi

Okwangoku, kukho iindawo zeli qela:

• -High speed;

• Plug (kusetyenziswa, umzekelo, xa crankshafts);

• oomatshini ngqo, ngokuchanekileyo esikhokelayo imigodi ukwenza hlengiso le gap;

• iindlela nesezantsi isantya cheap;

• yenzelwe ukusebenza phantsi kweemeko ezizodwa (amanzi, iindawo ezonakalisayo).

Kuxhomekeka imo yokusebenza elibizwa ngayo olu hlobo inokuba zochuku fluid okanye semifluid. Kwimeko yokuqala kumphezulu ukusebenza kwe izindlu nomphini ezahlulwa umaleko kunokuba kokulwa ioli. Xa ukukhuhlana mixed idityaniswe kumda ulwelo (i-oyile ngokusebenzisa ezicekethekileyo kakhulu umboniso lisekwa iibhondi emolekyuli).

Ubukhulu sliding iibheringi

Amacala sites kweli qela zigqitywa GOST 2795. Data ngokweetafile ezikhethekileyo - it kwakhona iyafuneka into ukuze bakuthathele ingqalelo ngokwenza iibheringi ezinjalo. Imigangatho kule meko sisebenza parameters ezifana:

• enobubanzi nomphandle wocango;

• ubude (l);

• chamfering ledayimenshini (C);

• nokumelana (nokumelana).

Le theyibhile ingezantsi (yinto enye) zimelwe yi ngobukhulu umgangatho sliding iibheringi lemiqolo ezahlukeneyo.

Iimpawu kunye neZixhobo

Standards of iibheringi mmandla, ngoko ke, ichazwa ngokungqongqo GOST. Ebekwe iimfuneko ezithile kumgangatho wasebenzisa izinto ngenxa yezandla zabo. Ukunikela izindlu izilayidi, njengoko sele kuchaziwe, kunokuba iphelele okanye uphuphu. Kwimeko yokugqibela, uqhagamshelwano isoloko isetyenziswa izikhonkwane ezizodwa okanye iibholiti. I yofako sisichazela sliding, njengoko kwisingxobo. Xa iqela elinye iqhekeza ukuba zingenziwa iziqingatha ezibini. Kwi imigodi, warping, ngokuqhelekileyo enyusiweyo iibheringi self-esalo.

Ezi zibonelelo zilandelayo zingasetyenziswa mveliso olu hlobo ezalathelwe uphuhliso:

• iron (izindlu);

• ubhedu, intsimbi, uphoswe okanye iplastiki (ukuba iiplagi).

Kwezinye iimeko, kodwa ngokuqinisekileyo inqabile kakhulu, bushings zenziwe ngomthi, okanye ichipboard.

iimfuneko zesiseko

Ngenxa yoko, imilinganiselo iibheringi (okanye mandithi, ukuphunyezwa) avumele ukuvelisa umgangatho eliphezulu, ixesha elide kunye nokusebenza kakhulu. iindawo ezithile qela kufuneka ufezekise ezi mfuno zilandelayo:

• Izinto kunye Uyilo iibheringi utyhala kufuneka ezifana ukubonelela ubuncinane zochuku phakathi kwezindlu kunye emkhonweni.

• Amandla kunye neyunithi ngqongqo kufuneka libe kwinqanaba elenza ukuba ukwazi ukumelana nayiphi ukulayisha oyifunayo.

• Zikude ubuninzi uyilo lula ukuzala. Ngexesha lokufaka kungabikho iingxaki.

• Ukuba avelise iibheringi ukuze ukuba indawo eyaneleyo some zisenzeka ngexesha nokusebenza kummandla ubushushu.

wenze njani

Yenza iibheringi plain kunye uzibhuqa kumashishini ezikhethekileyo ezinkulu, ngokuqhelekileyo oquka zocweyo ezimbini eziphambili: thermal nobomatshini. imigca Assembly ezinjalo izityalo rhoqo zisebenze kwimo oluzenzekelayo. Ngaphandle kwabo, iivenkile nazo efakwe koomatshini ukutshiza mihla.

Kwilizwe lethu ithandwa kakhulu lasi eyenziwe abenzi ekhaya, ngokunjalo e Switzerland (SKF). iibheringi standard SKF ziyafana in Russian.
