Isimiso sokuzala sendlela eyodwa

 

Ibhereni eliya ngakwesokudlauhlobo lwebheri elijikeleza ngokukhululeka kolunye uhlangothi bese likhiya kolunye. Indlu yensimbi yebheri yendlela eyodwa iqukethe ama-roller amaningi, ama-needle rollers noma amabhola, futhi ukuma kwesihlalo esigoqayo (imbobo) kusenza sigingqike kolunye uhlangothi kuphela, futhi kudale ukumelana okukhulu kolunye uhlangothi (okuthiwa "indlela eyodwa").

Umgomo wokusebenza wama-bearings ahamba ngendlela eyodwa

1. Umklamo we-ramp kanye ne-roller

Ama-clutch ohlobo lwe-ramp kanye ne-roller aqukethe indandatho yangaphandle enobubanzi bangaphakathi be-barrel, indandatho yangaphakathi ene-ramp, kanye nesethi yama-roller abhekene namandla entwasahlobo futhi ahlala ethintana kakhulu namasongo angaphakathi nangaphandle. Uma nje ukujikeleza komgwaqo owodwa womjaho ohlangothini lokunyakaza kwawo kunomthelela komunye, lokhu kulungiselela kuqinisekisa ukuthi kushesha ngale kwesivinini kanye nekhono lokushayela ngokushesha.

Ukusetshenziswa kwalolu hlobo lwe-clutch yendlela eyodwa kungafaneleka ekudluleni, ekuqondiseni nasekusetshenzisweni okungaguquki ezindaweni ezahlukahlukene.

Uma isetshenziswa njenge-clutch edlula yonke indlela

I-clutch ye-roller yohlobo lwe-ramp eyodwa izofakwa ngale ndlela, okungukuthi indandatho yangaphandle izosetshenziswa njengelungu lokudlula. Lokhu kubaluleke kakhulu ekudluleni ngesivinini esikhulu. Uma kwenzeka indandatho yangaphakathi idlula, amandla e-centrifugal asebenza kuma-roller azokhawulela isivinini sokudlula.

Uma isetshenziswa njenge-clutch engaguquki ngendlela eyodwa

I-clutch eyodwa yohlobo lwe-ramp roller ene-inner ring rotation kuphela efanelekela isivinini esiphansi. Uma kudingeka isivinini esiphezulu, kunconywa i-clutch eyodwa yohlobo lwe-wedge.

Uma isetshenziswa njenge-clutch yokukhomba indlela eyodwa

Indandatho yangaphandle ivame ukubonakala njengento ejikajikayo, kanti indandatho yangaphakathi ivame ukubonakala njengento eyisigqila. Ngaphandle kwalokho, ukungabi namandla kwama-rollers nama-spring kuzoholela emaphutheni, ikakhulukazi ekufakweni kwe-frequency ephezulu. Ukusetshenziswa kwamafutha okugcoba axutshwe kanye nama-spring anamandla kunikeza ukunemba kwe-index yesivinini esiphezulu kanye nekhwalithi ephezulu.

2. Umklamo we-wedge

Le clutch yohlobo lwe-wedge-type one-way override ngokuvamile yakhiwa yindandatho yangaphakathi, indandatho yangaphandle, iqembu le-wedge, ikheji le-wedge, isiphethu esinamandla kanye ne-bearing. I-wedge ihlanganiswa phakathi kwezindandatho zangaphakathi nezangaphandle ukuze kudluliselwe amandla kusuka kwenye indlela yomjaho kuya kwenye. I-wedge inamadayamitha amabili aqondile, (okungukuthi ibanga ukusuka ekhoneni elilodwa le-wedge kuya kwelinye) futhi enye yazo inkulu kunenye. Isenzo se-wedge senzeka lapho izindandatho zangaphakathi nezangaphandle zijikelezana, okuphoqa i-wedge ukuthi ibe nendawo ende eqondile engxenyeni enkulu kakhulu.

3. Umphumela we-wedge ye-angle yokuzikhiya uncike kakhulu ku-wedge kanye ne-angle yokuzikhiya ye-wedge phakathi kwamasongo angaphakathi nangaphandle. Umqondo oyisisekelo we-wedge one-way clutch udinga ukuthi i-coefficient of friction ye-wedge ihlobene ne-torque engazelelwe ekhiqizwa yi-inner ring ngaseceleni kwe-drive, futhi leli nani le-friction kumele libe likhulu kune-tangent value ye-angle yokuzikhiya. Uma izimo zingaphephile, i-wedge ngeke yenzeke.

I-engeli ezikhiyayo inqunywa yisakhiwo se-wedge, futhi amaphuzu asezindandatho zangaphakathi nezangaphandle axhunywe ne-wedge ngokulandelana.

Umklamo we-wedge une-engeli yokuqala ephansi kakhulu yokuzikhiya ukuqinisekisa ukubopha okuphelele ekuqaleni. Njengoba i-torque ikhula, kukhiqizwa amandla e-radial ku-wedge ephambukisa umzila we-wedge, okwenza i-wedge igoqeke iye endaweni entsha. I-wedge ivame ukuklanywa ukuthi ibe ne-engeli yokuzikhiya engakhushulwa kancane kancane, njengoba nje isuka endaweni yokudlula kuze kube yilapho umthwalo omkhulu ubhekwe khona. I-engeli enkulu yokuzikhiya inciphisa amandla e-radial akhiqizwa yi-wedge, ukuze ama-torque amakhulu avunyelwe ukudluliselwa inqobo nje uma kudingeka imikhawulo yobude kanye nobunzima be-Brinell.

Ukusetshenziswa okuyinhloko kwama-bearings ahamba ngendlela eyodwa: imishini yendwangu; Imishini yokunyathelisa; imboni yezimoto; Izinto zasendlini; Isitholi somgunyathi.
