Kutheni ukudlala i-radial kunye nokunyamezelana ayifani

Kukho isiphithiphithi esijikeleze ubudlelwane phakathi kokuchaneka kwebheringi, ukunyamezelana kwemveliso kunye nenqanaba lokususwa kwangaphakathi okanye 'ukudlala' phakathi komdyarho neebhola. Apha, uWu Shizheng, umlawuli olawulayo weengcali ezincinci kunye ezincinci zeebheringi zeJITO, usinika ukukhanya ukuba kutheni le ntsomi iqhubeka kwaye zeziphi iinjineli ekufuneka zijongile.

Ngexesha leMfazwe yesibini yeHlabathi, kwifektri yezixhobo zokusebenza eScotland, indoda encinci eyaziwayo egama linguStanley Parker yavelisa umbono wobume bokwenyani, okanye into esiyaziyo namhlanje njengeGeometric Dimensioning & Tolerancing (GD&T). UParker uqaphele ukuba nangona ezinye izinto ezisebenzayo zenzelwa ii-torpedoes zazingamkelwa emva kovavanyo, zazisathunyelwa kwimveliso.

Ekuqwalaselweni ngokusondeleyo, wafumanisa ukuba yayiyindlela yokunyamezelana enetyala. Imveli XY yokulungelelanisa ukunyamezelana yenze indawo yokunyamezelana, eyikhuphele ngaphandle le ndawo nangona yayihlala kwindawo ejikeleze isangqa phakathi kweekona zesikwere. Uqhubeke nokupapasha iziphumo zakhe malunga nendlela yokufumana indawo eyiyo kwincwadi enesihloko Imizobo kunye neMilinganiselo.

Ukucoca kwangaphakathi
Namhlanje, oku kuqonda kusinceda ukuba siphuhlise iibheringi ezibonisa inqanaba lokudlala okanye ukungakhathali, kungenjalo kwaziwa njengokucoca ngaphakathi okanye, ngakumbi, umdlalo we-radial kunye ne-axial. Ukudlala ngokurhabaxa kukususwa okulinganiselwe ngokungafaniyo kwi-axis ethweleyo kunye nokudlala kwe-axial kukucaciswa okulinganiswe ngokuhambelana ne-axis ethwele.

Lo mdlalo uyilelwe ukuthwala kwasekuqaleni ukuvumela ukuthwala ukuxhasa imithwalo kwiimeko ezahlukeneyo, kuthathelwa ingqalelo izinto ezinje ngokwandiswa kweqondo lobushushu kunye nendlela ulungelelwaniso phakathi kwamakhonkco angaphakathi nangaphandle anokuchaphazela ubomi bokuzala.

Ngokukodwa, ukucocwa kunokuchaphazela ingxolo, ukungcangcazela, uxinzelelo lobushushu, ukuphambuka, ukuhanjiswa komthwalo kunye nobomi bokukhathala. Ukudlala okuphezulu kwe-radial kuyanqweneleka kwiimeko apho iringi yangaphakathi okanye ishafti kulindeleke ukuba ishushu kwaye yande ngexesha lokusetyenziswa xa kuthelekiswa neringi yangaphandle okanye indlu. Kule meko, umdlalo oza kuthwala uya kuncipha. Ngokuchaseneyo, umdlalo uya kwanda ukuba iringi yangaphandle iyanda ngaphezu kweringi yangaphakathi.

Ukudlala okuphezulu kwe-axial kuyanqweneleka kwiinkqubo apho kukho ukungalungelelani phakathi kweshafti kunye nezindlu njengoko ukungalungelelani kunokubangela ukuthwala kunye nokhuseleko oluncinci lwangaphakathi ukusilela ngokukhawuleza. Ukucinywa okukhulu kunokuvumela ukuthwala ukuba kumelane nemithwalo ephezulu njengoko izisa i-engile ephezulu yokunxibelelana.

Ulungelelwaniso
Kubalulekile ukuba iinjineli zibethe ibhalansi efanelekileyo yokucaca kwangaphakathi kwindawo. Ukuqina okungaphaya kokudlala ngokungonelanga kuya kwenza ubushushu kunye nokukhuhlana okungaphaya, okuya kuthi kubangele ukuba iibhola zityibilike kwindlela yomdyarho kwaye zikhawuleze ukunxiba. Ngokukwanjalo, ukucoca okuninzi kuyonyusa ingxolo kunye nokungcangcazela kunye nokunciphisa ukujikeleza ngokuchanekileyo.

Ukucoca kunokulawulwa ngokusebenzisa ulungelelwaniso olwahlukileyo. Ukulingana kobunjineli kubhekisa kusetyenziso phakathi kwamalungu amabini okutshatisa. Oku kuhlala kuchazwa njenge-shaft emngxunyeni kwaye kubonisa inqanaba lokuqina okanye ukungahambi kakuhle phakathi kweshafti kunye neringi yangaphakathi naphakathi kweringi engaphandle kunye nezindlu. Ihlala izibonakalisa kwindawo evulekileyo, yokuvunyelwa okanye yokuqina, yokungenelela.

Ukulunga okuxineneyo phakathi kweringi yangaphakathi kunye neshafti kubalulekile ukuyigcina ikwindawo kunye nokuthintela ukuthambeka okungafunekiyo okanye islippage, enokuthi ivelise ubushushu kunye nokungcangcazela kunye nokwenza ukuthotywa.

Nangona kunjalo, ukungqinelana kokuphazamiseka kuya kunciphisa ukucocwa kwebhola njengoko isandisa isangqa sangaphakathi. Ukulingana ngokulinganayo phakathi kwendlu kunye nendandatho yangaphandle ekubambeni ngokudlala okuphantsi kwe-radial kuya kucinezela iringi yangaphandle kwaye kunciphise ukucocwa ngakumbi. Oku kuyakukhokelela kugqatso lwangaphakathi olungelulo-ekunikezeleni nge-shaft enkulu kunomngxunya-kwaye kukhokelele kungqubano olugqithisileyo kunye nokusilela kwangoko.

Injongo kukuba nomdlalo ongasebenziyo xa umdlalo usebenza phantsi kweemeko eziqhelekileyo. Nangona kunjalo, umdlalo wokuqala we-radial ofunekayo ukufezekisa oku kunokubangela iingxaki ngebhola ukuskiya okanye ukutyibilika, ukunciphisa ukuqina kunye nokujikeleza ngokuchanekileyo. Lo mdlalo wokuqala we-radial ungasuswa usebenzisa ukulayisha kwangaphambili. Ukulayishwa kwangaphambili yindlela yokubeka umthwalo osisigxina kwi-bearing, emva kokuba ulungisiwe, ngokusebenzisa ii-washer okanye imithombo elungiselelwe ngaphakathi kwendandatho yangaphakathi okanye yangaphandle.

Iinjineli kufuneka ziqwalasele into yokuba kulula ukunciphisa ukucoca kwindawo encinci ngoba amakhonkco anciphile kwaye kulula ukuwaqhawula. Njengomvelisi weebheringi ezincinci nezincinci, iJITO Bearings icebisa abathengi bayo ukuba ukhathalelo olungaphezulu kufuneka luthathwe ngokulingana kweshaft-to-housing. Ishafti kunye nokujikeleza indlu kubaluleke ngakumbi kuhlobo olucekeceke lweebheringi kuba ishedyuli engaphandle iya kukhubaza amakhonkco amancinci kwaye inyuse ingxolo, ukungcangcazela kunye ne-torque.

* Ukunyamezelana
Ukungaqondi malunga nendima yomdlalo we-radial kunye ne-axial kukhokelele uninzi ukuba lubhidanise ubudlelwane phakathi komdlalo kunye nokuchaneka, ngakumbi ukuchaneka okubangelwa kukunyamezelana okungcono kokuvelisa.

Abanye abantu bacinga ukuba ukuthwala ngokuchaneka okuphezulu akufuneki kube nokudlala kwaye kufuneka kujikeleze ngokuchanekileyo. Kubo, umdlalo ovulekileyo weradial uziva ungachanekanga kangako kwaye unika umbono wokumgangatho osezantsi, nangona inokuba kukuchaneka okuphezulu okwenziwe ngabom ngokudlala ngokukhululekileyo. Umzekelo, siye sabuza abanye babathengi bethu kwixa elidlulileyo ukuba kutheni befuna ukuthwala okuthe kratya kwaye basixelele ukuba bafuna, "ukunciphisa umdlalo".

Nangona kunjalo, kuyinyani ukuba ukunyamezelana kuphucula ukuchaneka. Kungekudala emva kokuveliswa kwemveliso ezininzi, iinjineli zaqonda ukuba ayisebenzi kwaye ayisiyoqoqosho, ukuba kunokwenzeka konke oko, ukuvelisa iimveliso ezimbini ezifanayo. Naxa zonke izinto eziguquguqukayo zigcinwa ngokufanayo, kuyakuhlala kukho umahluko wemizuzu phakathi kweyunithi nenye elandelayo.

Namhlanje, oku kuye kwamela unyamezelo oluvumelekileyo okanye olwamkelekileyo. Iiklasi zokunyamezelana kweebheringi zebhola, ezaziwa njenge-ISO (metric) okanye i-ABEC (intshi) yokulinganisa, ukumisela ukuphambuka okuvumelekileyo kunye nemilinganiselo yokugubungela ubungakanani bendandatho yangaphakathi nangaphandle kunye nokujikeleza kweeringi kunye neendlela zendlela. Ukuphakama kweklasi kunye nokunyamezela ukunyamezela, ngokuchanekileyo ukuthwala kuya kuba kanye xa kuhlanganisiwe.

Ngokubetha ibhalansi elungileyo phakathi kokudibanisa kunye nokudlala ngokurhabaxa kunye nokudlala ngexesha lokusetyenziswa, iinjineli zinokufezekisa ukucocwa kokungabikho kokusebenza kunye nokuqinisekisa ingxolo ephantsi kunye nokujikeleza ngokuchanekileyo. Ngokwenza njalo, sinokususa isiphithiphithi phakathi kokuchaneka kunye nokudlala kwaye, ngendlela efanayo naleyo uStanley Parker aguqule ngayo umlinganiso wezezemveliso, utshintshe ngokusisiseko indlela esijonga ngayo iibheringi.
