Isitshixo esinxuseneyo neGroove, iCartbon Steel, iStainless Steel

Isitshixo esisicaba sisitshixo esixhomekeke kumacala amabini njengendawo yokusebenza, kwaye i-torque ihanjiswa ngokukhutshwa kwesitshixo kunye necala lendlela engundoqo.

Ngokokusetyenziswa okwahlukeneyo, isitshixo esisicaba sinokwahlulwa ngokweendidi ezine: isitshixo esisicaba esiqhelekileyo, isitshixo esisicaba esibhityileyo, isitshixo esisicaba kunye nesitshixo sokutyibiliza.Phakathi kwazo, isitshixo esisicaba esiqhelekileyo kunye nesitshixo esibhityileyo sisetyenziselwa uqhagamshelo olungagungqiyo, kwaye isikhokelo esisicaba sisetyenziselwa unxibelelwano oluguqukayo.

I-DIN6885 isitshixo esisicaba esiqhelekileyo sahlulwe ngokwesitshixo esisicaba esingqukuva uhlobo lwentloko A, isitshixo esisicaba esisikwere sentloko yohlobo B, isitshixo esisicaba esinye esingqukuva sentloko uhlobo C. Imilinganiselo engundoqo yesakhiwo sezitshixo ezisicaba eziqhelekileyo bububanzi bobhondi b, ubude bobhondi h, kunye nobude bobhondi L. .
Uhlobo lwe-A: Intloko ejikelezayo, i-anti-rotation, i-keyway ifakwe ngomatshini wokuphela kwaye inesimo esifanayo ne-groove, kwaye kukho i-gap phakathi komphezulu we-keytop kunye ne-hub.

Uhlobo lwe-B: intloko ecwecwe, elungiswe ngezikrufu, isitshixo se-shaft kufuneka sitshintshwe nge-disc milling cutter, kwaye iziphelo ezimbini aziqiniswanga emva kokuhlanganisana.

Uhlobo C: Esinye isiphelo sijikelezileyo kwaye esinye isiphelo sisikwele, sicutshungulwa yi-cut milling cutter, esetyenziselwa ukudibanisa i-shaft end kunye ne-hub.

I-DIN6885 iqhosha leflethi libhekiselele kwi-DIN6885 yaseJamani esemgangathweni, ehambelana nomgangatho wesizwe we-GB / T1096-2003.Umgangatho ukhankanya udidi oluqhelekileyo lwe-A, uhlobo lwe-B, kunye nohlobo lwezitshixo ezisicaba ezinobubanzi obuyi-b=2mm-100mm.

Indlela yokumakisha iqhosha elisicaba
Indlela yokubhala iqhosha leflethi liquka igama, ifom engundoqo, ububanzi obuphambili b × ukuphakama kwesitshixo h × ubude beqhosha L, DIN6885.

Umzekelo: Chwetheza isitshixo esisicaba esiqhelekileyo, b=8, h=7, L=25, esiphawulwe njenge: Isitshixo seflethi A uhlobo 8×7×25 DIN6885, ukuba luhlobo B isitshixo esisicaba esiqhelekileyo, ubungakanani buyafana ne ngasentla, ngoko iphawulwe njenge: flat Key B uhlobo 8×7×25 DIN6885.

I-DIN6885 izitshixo ezisicaba zenziwe ngentsimbi yekhabhoni kunye nentsimbi engenanto.Isitshixo esisicaba esibonelelwe yi-Screw Street senziwe ngensimbi engenasici, eyenziwe nge-SUS304 yensimbi engenasici, inamandla amakhulu kunye nokuxhathisa okuqinileyo kwe-corrosion.

Izinto eziphathekayo zesitshixo se-flat zihambelana nezinto ze-shaft kunye nezinye iindawo ze-rotor.Ngokubanzi, intsimbi ye-45 ingasetyenziselwa kwimeko yokungabikho kwe-corrosion, kodwa kwindawo engcolileyo, isiganeko kunye nomthombo wokubola kwesitshixo se-flat kufuneka sithathelwe ingqalelo, njengolwelo lwezitshixo ezicangcayo ezidibana neendaba ezinobundlobongela, ukubola. kweendaba kufuneka ziqwalaselwe, kwaye izinto ezihambelanayo kufuneka zikhethwe, ngakumbi kwiindawo ezine-acidic.Ukukhethwa kwezinto eziphathekayo kubaluleke kakhulu.Ii-asidi ezahlukeneyo kunye nee-asidi ezixubileyo zinokwahlukana okukhulu kwizinto ezihambelanayo, ngoko kufuneka kuhlawulwe ingqalelo.

Amandla okuqina kwe-DIN6885 isitshixo esisicaba akufuneki sibe ngaphantsi kwe-590MPa.

I-DIN6885 isitshixo seflethi esiqhelekileyo sinokungathathi hlangothi okulungileyo, ukuchaneka kokuma okuphezulu, isakhiwo esilula kunye nokuchithwa okulula kunye nokuhlanganisana, kodwa ayikwazi ukufezekisa ukulungiswa kwe-axial yeengxenye kwi-shaft, kwaye isetyenziselwa i-shafts okanye i-shafts ehambelana nefuthe kunye nemithwalo eguquguqukayo.

Isitshixo esisicaba sohlobo lwe-A sisebenzisa isiphelo sokusila ukucubungula indlela engundoqo kwishaft.Isitshixo sigxininiswe kwi-groove kwaye uxinzelelo lugxininisekile.Yeyona isetyenziswa kakhulu kwaye isoloko isetyenziswa kwiifasteners kwishishini lomatshini.Isitshixo sohlobo lwe-B sisebenzisa i-disc milling cutter ukucubungula indlela engundoqo kwi-shaft, kwaye uxinzelelo loxinzelelo luncinci.Iqhosha le-C-type lisetyenziswa ngokubanzi kwi-shaft end.

Ukukhetha ubungakanani besitshixo esisicaba: ubukhulu becandelo b × h yesitshixo esisicaba sikhethwe ukusuka kumgangatho ngokwe-diameter d ye-shaft.Ubude beqhosha L ngokuqhelekileyo bunqunywe ngokuhambelana nobubanzi be-hub, kwaye ubude beqhosha kufuneka bube bufutshane kancinci kune-hub nge-5 ~ 10 mm, kwaye ihambelana nexabiso lechungechunge lobude.

Ubungcali kwimveliso ye-DIN6855 izitshixo ezisicaba kunye neenkcukacha ezipheleleyo kunye nomgangatho othembekileyo, wamkelekile ukubonisana nokuthenga.
