Iindlela Zokukhetha Iintambo Zerola Ezimfutshane Eziphakathi

Iindlela zokukhetha i-short center pitch roller chain: Ukuhambelana ngokuchanekileyo neemeko zokusebenza kunye nokunciphisa iingozi emva kokuthengisa kubasasazi.Iitsheyini ezijikelezayo zepitch emfutshane embindinizisetyenziswa kakhulu kwizixhobo zothumelo ezincinci, imigca yemveliso ezenzekelayo, kunye noomatshini abachanekileyo ngenxa yokuziqhelanisa neendawo ezincinci kunye nesantya sokuphendula ngokukhawuleza. Njengomsasazi wehlabathi, xa ucebisa iimodeli kubathengi, kubalulekile ukuqwalasela zombini ukuhambelana kwezixhobo kunye nokunciphisa umngcipheko wokubuyiselwa, ukutshintshiselana, kunye neengxabano zasemva kokuthengisa ezibangelwa kukukhetha okungafanelekanga. Eli nqaku lihlalutya ingqiqo yokukhetha ephambili yeentambo ezimfutshane ze-pitch roller ukusuka kwimbono yeemeko zesicelo ezisebenzayo, ukukunceda ngokukhawuleza nangokuchanekileyo ukuhambelana neemfuno zabathengi.

I. Izinto Ezintathu Ezibalulekileyo Ezifunekayo Ngaphambi Kokukhetha

Eyona nto iphambili ekukhetheni “kukulungisa isisombululo.” Kwiimeko ezimfutshane zokuphosa embindini, indawo yezixhobo incinci kwaye iimfuno zokuchaneka kokudluliselwa kombane ziphezulu. Ulwazi oluphambili olulandelayo kufuneka luchongwe kuqala:
Iiparamitha zokusebenza eziphambili: Cacisa umthwalo wokwenyani wezixhobo (kubandakanya umthwalo olinganisiweyo kunye nomthwalo wempembelelo), isantya sokusebenza (rpm), kunye nobushushu bokusebenza (-20℃ ~ 120℃ luluhlu oluqhelekileyo; iindawo ezikhethekileyo kufuneka zichazwe).

Iinkcukacha zoMqathango weNdawo: Linganisa umgama obekelwe indawo yokufakela kunye nenani lamazinyo e-sprocket yezixhobo zokulinganisa ukuqinisekisa indawo yokuqinisa utyathanga (isibonelelo sokuqinisa umgama omfutshane phakathi kweendawo sidla ngokuba yi-≤5% ukuze kuthintelwe ukunwebeka kakhulu).

Iimfuneko zokuZiqhelanisa neNdalo: Cinga ngobukho bothuli, ioyile, izinto ezibangela ukubola (ezifana neendawo zeekhemikhali), okanye iimeko zokusebenza ezikhethekileyo ezifana nokuma kokuqala okukhawulezayo, okanye impembelelo ebuyela umva.

II. Iindlela ezi-4 zokukhetha izinto ezibalulekileyo zokuthintela iingxaki

1. Inombolo yeTyeya kunye nePitch: "Ubungakanani obubalulekileyo" boMgama oMfutshane oPhakathi
Beka phambili ukhetho ngokusekelwe kumgaqo othi “iphimbo elincinci, imigca emininzi”: Ngemigama emifutshane esembindini, iitsheyini ezincinci zephimbo (ezifana ne-06B, 08A) zibonelela ngokuguquguquka okukhulu kwaye zinciphisa umngcipheko wokuxinana; xa umthwalo unganele, beka phambili ukunyusa inani lemigca (endaweni yokwandisa iphimbo) ukuze uphephe impembelelo yokudluliselwa okugqithisileyo ngenxa yephimbo elikhulu kakhulu.

I-Sprocket Efanisa Inombolo Yetyathanga: Qinisekisa ukuba i-chain pitch ihambelana ngokupheleleyo ne-sprocket pitch yezixhobo zomthengi. Kwiimeko ezimfutshane zomgama ophakathi, kucetyiswa ukuba inani lamazinyo e-sprocket libe ngamazinyo ayi-≥17 ukunciphisa ukuguguleka kwetyathanga kunye namathuba okutsiba kwamazinyo.

2. Ukukhethwa koBume: Ukuziqhelanisa neempawu zoThumelo olufutshane oluPhakathi-iPitshi

Ukukhetha Uhlobo lweRoller: Iitsheyini zeroller eziqinileyo zisetyenziswa ngokubanzi ngenxa yokumelana kwazo nokuguguleka kwazo kunye nomthamo wazo ozinzileyo wokuthwala umthwalo; iitsheyini zeroller ezingenanto ziyacetyiswa kwiimeko zokudlulisela ngesantya esiphezulu okanye ngokuchanekileyo ukunciphisa impembelelo ye-inertial.

Ukuhambelana kohlobo lokudibanisa: Kwiinkqubo ezimfutshane eziphakathi nendawo ezinesithuba esincinci sokufakela, ii-spring clip joints ziyathandwa (ukuze kube lula ukuziqhaqha); ii-cotter pin joints zisetyenziselwa iimeko zokuhambisa ezisebenza nzima okanye ezithe nkqo ukuphucula amandla oqhagamshelo.

Inani leMigca yokuQhuba: Iitsheyini zomqolo omnye zifanelekile kwizicelo zomthwalo olula, ezikhawulezayo (njengezixhobo ezincinci zokuhambisa); iitsheyini zomqolo ophindwe kabini/kathathu zisetyenziselwa izicelo zomthwalo ophakathi ukuya konzima (njengothumelo lwezixhobo zomatshini ezincinci), kodwa kufuneka kuqwalaselwe ukuchaneka kwesithuba semigca yeetsheyini zemigca emininzi ukuze kuthintelwe uxinzelelo olungalinganiyo.

3. Unyango lwezinto kunye nobushushu: Ukuziqhelanisa neemfuno zeNdalo kunye nexesha lokuphila

Iimeko-bume ngokubanzi: Iirola ezenziwe ngezinto ze-20MnSi ziyakhethwa, emva konyango lwe-carburizing kunye nokucima, zifezekisa ubunzima be-HRC58-62, zihlangabezana neemfuno zokumelana nokuguguleka kwezicelo ezininzi zoshishino.

Iindawo Ezikhethekileyo: Kwiindawo ezirhabaxa (ezifana neendawo zangaphandle nezixhobo zeekhemikhali), intsimbi engagqwaliyo (304/316) iyacetyiswa; kwiindawo ezishushu kakhulu (>100℃), kufuneka kukhethwe izinto ze-alloy ezinobushushu obuphezulu, kunye negrisi enobushushu obuphezulu.

Iimfuneko eziQinisekisiweyo: Kwiimeko zokumisa nokuyeka ukuqalisa okanye umthwalo ochaphazelekileyo, khetha iitsheyini ezinee-phosphated rollers kunye nee-bushings ukuphucula amandla okudinwa kunye nokumelana nokugqwala.

4. Ukulungelelaniswa koFakelo kunye noLondolozo: Ukunciphisa iindleko zokusebenza kwabathengi

Ukuqwalasela Iimpazamo Zokufakela: Umgama omfutshane phakathi kwesakhiwo ufuna i-coaxiality ephezulu ngexesha lokufakelwa. Iityathanga ezinonyango "lwangaphambi koxinzelelo" ziyacetyiswa ukunciphisa ukuguquguquka emva kokufakelwa.

Ukuziqhelanisa nokuthambisa: Ukuthambisa ngegrisi kusetyenziswa kwiindawo ezivalekileyo, kunye nokuthambisa ngeoyile kwiindawo ezivulekileyo. Xa isantya setsheyini siphezulu ngomgama omfutshane embindini, kuyacetyiswa ukusebenzisa izikhonkwane zokuthambisa ngokwazo ukunciphisa amaxesha okugcinwa kwabathengi.

Ukuqinisekiswa Kwamandla Avumelekileyo: Amandla avumelekileyo etsheyini enomgama omfutshane embindini aya kuncipha njengoko isantya sisanda. Kubalulekile ukuqinisekisa amandla avumelekileyo ngokwetheyibhile yomenzi ethi “Umgama Ophakathi – Isantya – Amandla Avumelekileyo” ukuze kuthintelwe ukusebenza ngokugqithisileyo.

III. Iimpazamo Ezintathu Eziqhelekileyo Zokukhetha Abathengisi Abafanele Baziphephe

Impazamo 1: Ukusukela ngokungaboniyo “amandla aphezulu” nokukhetha imixokelelwane emikhulu enomqolo omnye. Imixokelelwane emikhulu enomgama omfutshane embindini ayinakuguquguquka kwaye ikhokelela ekugugulekeni ngokukhawuleza kwe-sprocket, ngaloo ndlela inciphisa ubomi bayo bokusebenza.

Impazamo yesi-2: Ukungawunaki ukuhambelana kwendalo kunye nokusebenzisa imixokelelwane eqhelekileyo kwiindawo ezirhabaxa/ezinobushushu obuphezulu. Oku kukhokelela ngokuthe ngqo ekugqweseni kwangethuba kunye nokuqhekeka kwemixokelelwane, okubangela iingxabano emva kokuthengisa.

Impazamo 3: Ukugxila kuphela kwinani leetyathanga ngaphandle kokuqwalasela ukuchaneka kokwenziwa. Iidrives zomgama omfutshane zifuna ukuchaneka kwe-chain pitch ephezulu. Kucetyiswa ukuba ukhethe iityathanga ezihlangabezana nemigangatho ye-ISO 606 ukunciphisa ukungcangcazela kokudluliselwa.

IV. Isishwankathelo seNkqubo yoKhetho lweTyathanga leRoller eliPhakathi eliMfutshane

Qokelela iiparameter zokusebenza kwabathengi (umthwalo, isantya, ubushushu, indawo);
Okokuqala chonga inani letsheyini ngokusekelwe kwi-“pitch matching sprocket + inani lemigca ehambelana nomthwalo”;
Khetha izixhobo kunye neendlela zonyango lobushushu ngokusekelwe kwindalo esingqongileyo;
Misela uhlobo lokudibana kunye nesicwangciso sokuthambisa ngokusekwe kwindawo yokufakela kunye neemfuno zolondolozo;
Jonga amandla avumelekileyo ukuqinisekisa ukuba izixhobo ziyahambelana neemfuno zokusebenza.
