Uthelekiso lokuchaneka kokudluliselwa kwentambo phakathi kwee-Roller Chains kunye nee-Toothed Chains

Uthelekiso lokuchaneka kokudluliselwa kwentambo phakathi kwee-Roller Chains kunye nee-Toothed Chains

I. Ingqiqo Esisiseko Yokuchaneka Kokudluliselwa: Umahluko Kwisakhiwo Umisela Umda Ophezulu Wokusebenza

1. I-Bottleneck ye-Roller Chains echanekileyo: Isiphumo se-Polygonal kunye nokuNxiba okungafanelaniyo
Iiroller chains zenziwe ngeeroller, iibushings, iipins, kunye neeplate zechain. Ngexesha lokudibanisa i-meshing, amandla adluliselwa ngokunxibelelana kwenqaku phakathi kweeroller kunye namazinyo e-sprocket. Iziphene zayo zokuchaneka kwe-core zivela kumanqaku amabini: **Isiphumo sePolygonal:** I-chain yenza isakhiwo se-polygonal esiqhelekileyo esijikeleze i-sprocket. Okukhona i-pitch P inkulu kwaye amazinyo e-sprocket embalwa, kokukhona ukuguquguquka kwesantya okukhawulezileyo (ifomula: v=πd₁n₁/60×1000, apho i-d₁ ilububanzi besangqa se-sprocket pitch), okukhokelela kumlinganiselo wokudluliselwa ongaguqukiyo. **Ukwaphuka okungalinganiyo:** Emva kokuwohloka kwehinge, i-outer link pitch iyanda kakhulu ngelixa i-inner link igcina ubungakanani bayo bokuqala, idala umahluko we-pitch okhawulezisa ukubola okuchanekileyo.

2. Iingenelo ezichanekileyo zeetyathanga ezinamazinyo: I-Involute meshing kunye nokwandiswa okufanayo. Iityathanga ezinamazinyo (ezaziwa ngokuba ziityathanga ezithuleyo) zixhonywe kwiiplate zetyathanga ezinamazinyo eziqingqiweyo. I-line contact meshing ifumaneka ngeprofayili yamazinyo etyathanga kunye neprofayili yamazinyo e-involute ye-sprocket: **Iimpawu ze-multi-tooth meshing:** Umlinganiselo wokugqithana ufikelela kwi-2-3 (iityathanga eziqengqelekayo kuphela...). 1.2-1.5), usasaza umthwalo ngelixa kuqinisekiswa ukuqhubeka kokudluliselwa. Uyilo lokunxiba olufanayo: Ukwandiswa ngokubanzi kwekhonkco ngalinye letyathanga kuyahambelana emva kokuguguleka, akukho kuphambuka kwepitch yendawo, okubangela ukuba kugcinwe ukuchaneka okungcono kwexesha elide. Ulwakhiwo lwesikhokelo olulungiselelweyo: Uyilo lwangaphakathi lwesikhokelo luphepha intshukumo esecaleni, kwaye ulawulo lweempazamo zokufana phakathi kwezi shafts zichaneke ngakumbi.

II. Uthelekiso loBuninzi lweZibonakaliso zokuChaneka koThumelo oluPhambili

III. Izinto eziphambili zangaphandle ezichaphazela ukuchaneka kokudluliselwa

1. Uvakalelo kwiNgqiqo yoFakelo: Iitsheyini ezinamazinyo zineemfuno eziphezulu kakhulu zokufana kweeshafti ezimbini (impazamo ≤ 0.3mm/m), kungenjalo ziya kwenza kube nzima ukuguguleka kweepleyiti zetsheyini kwaye zibangele ukwehla okukhulu kokuchaneka. Iitsheyini eziqengqelekayo zivumela iimpazamo ezinkulu zokufakela (≤ 0.5mm/m), zilungelelanise neemeko zokubeka izinto ezinzima phantsi kweemeko zokusebenza ezinzima.

2. Impembelelo yoMthwalo kunye neSantya: Umthwalo onzima onesantya esiphantsi (<500rpm): Umahluko wokuchaneka phakathi kwezi zimbini unciphile, kwaye iiroller chains zinoqoqosho ngakumbi ngenxa yenzuzo yazo yeendleko. Ukuchaneka kwesantya esiphezulu (>2000rpm): Inzuzo yokucinezelwa kwesiphumo se-polygon yee-toothed chains iyabonakala, kwaye izinga lokubola kokuchaneka liyi-1/3 kuphela lee-roller chains.

3. Ukubaluleka Kokuthambisa Nokugcina Izinto Zisemgangathweni Ekulungiseni Izinto Ngokuchanekileyo: Iiroller chains zikhawuleza ukuguguleka ngokuphindwe kathathu ukuya kahlanu xa zingenazo izinto zokuthambisa, kwaye impazamo yepitch iyanda ngokukhawuleza. Iiroller chains zifuna ukucocwa rhoqo kunye nokuthambisa ukuze kugcinwe ukuchaneka kweendawo zokungqubana ezityibilikayo, nto leyo ebangela iindleko eziphezulu zokulungisa kuneeroller chains.

IV. Isikhokelo sokukhetha esisekelwe kwiimeko: Iimfuno ezichanekileyo zibaluleke kakhulu kuneendleko

1. Imizekelo yokusetyenziswa kweTyathanga elinamazinyo:
Izixhobo zokuchaneka ngesantya esiphezulu: Ukudluliselwa kwexesha lenjini, isixhobo somatshini sokuchaneka sokuqhuba i-spindle (isantya > 3000 r/min)
Iindawo ezingenangxolo iphantsi: Oomatshini belaphu, izixhobo zonyango (imfuneko yengxolo < 60dB)
Uthumelo oluhamba kakuhle olunzima: Oomatshini bokwemba, izixhobo zesinyithi (i-torque > 1000 N·m)

2. Imizekelo yokusetyenziswa kweRoller Chain:
Oomatshini ngokubanzi: Oomatshini bezolimo, imigca yokuhambisa izinto (isantya esiphantsi, umthwalo onzima, imfuneko yokuchaneka ±5%)
Iindawo ezinobungozi: Iimeko zothuli/ezinomswakama (isakhiwo esilula, amandla aqinileyo okulwa nongcoliseko)
Iiprojekthi ezixabisa kakhulu: Ixabiso le-roller chain enomqolo omnye lincinci kakhulu kunelo le-toothed chain eneempawu ezifanayo. 40%-60%

V. Isishwankathelo: Ubugcisa bokulinganisela ukuchaneka nokusebenza

Eyona nto iphambili yokuchaneka kothumelo sisiphumo esipheleleyo soyilo lwesakhiwo, ukucubungula izinto, kunye nokuziqhelanisa neemeko zokusebenza: Iitsheyini ezinamazinyo zifikelela kubuchule obuphezulu kunye nokuzinza okuphezulu ngezakhiwo ezintsonkothileyo, kodwa zibangela iindleko eziphezulu zokuvelisa kunye neemfuno zokufakela; Iitsheyini eziqengqelekayo zincama ukuchaneka okuthile ngenxa yokuguquguquka, iindleko eziphantsi, kunye nokulula kokugcinwa. Xa ukhetha imodeli, iimfuno eziphambili kufuneka zibekwe phambili: Xa imfuneko yempazamo yomlinganiselo wothumelo i-<±1%, isantya singaphezulu kwe-2000 r/min, okanye ulawulo lwengxolo lungqongqo, iitsheyini ezinamazinyo zesona sisombululo sifanelekileyo; ukuba iimeko zokusebenza zinzima, uhlahlo-lwabiwo mali lulinganiselwe, kwaye ukunyamezelana kokuchaneka kuphezulu, iitsheyini eziqengqelekayo zihlala zilukhetho oluthembekileyo kushishino.
