Ngesiqhelo unokuva iindlela ezahlukeneyo ngokwenza iigiya ze-bevel, ezibandakanya iigiya ze-bevel ezithe tye, iigiya ze-bevel ezijikelezayo, iigiya zesithsaba okanye iigiya ze-hypoid.
KukuSila, ukuLapping kunye nokuSila.Ukugaya yeyona ndlela isisiseko yokwenza iigiya ze-bevel.Ke emva kokugaya, abanye abathengi bakhetha i-lapping, abanye abathengi bakhetha ukugaya.Yintoni umahluko ?
I-Lapping yeyokugqiba, eyona njongo ibalulekileyo yamazinyo ophando kukunciphisa ingxolo kunye nokuphucula ukudibana komphezulu wezinyo legiya.I-Lapping yindlela yokugqiba yokulungisa iimpazamo zamazinyo kunye nokuphucula umgangatho ophezulu.Ngenxa yempazamo ebangelwe kukusika/ukusila okanye ukunyangwa kobushushu benyathelo langaphambili, ukuchaneka kwe-meshing kuthotywa, injongo yamazinyo kukubalekela indawo yokunxibelelana yevili ukuphucula iimpawu zokuqengqeleka kwezinyo elibolileyo, ukuqinisekisa izinyo ivili ngokuzolileyo, ukuphucula isakhono somthwali.
I-Lapping yinkqubo encinci yokusika isinyithi, egqitywe ngesantya kunye nokunyanzeliswa okuhambelana nokuchasana nomgangatho wezinyo.Ubuncinci ugqirha wamazinyo ufuna ukunciphisa ingxolo, iqondo lokunciphisa ingxolo liyahluka ngokuxhomekeke kwinkqubo yeeparamitha zenkqubo yamazinyo kunye neemeko ze-gear sub-initial.Ukuphuculwa kwezinyo kwingxolo kunokulinganiswa ngeendlela ezahlukeneyo zokuchaneka kwe-pulse level.Izinyo lophando nalo alifuni umthamo womthwalo wesibini segiya, ukusuka kwelinye i-angle, oko kukuthi, indawo yokunxibelelana yamazinyo ayibhubhisi ivili, kungcono ukuba uphucule ngokufanelekileyo indawo yokunxibelelana ejikelezayo.
Nangona i-lapping ayinakuguqulwa ngokuchanekileyo kwiperi yegiya njengendlela yokugaya, ukuphucula inqanaba lokuchaneka kwegiya, kodwa ngetekhnoloji yolawulo yendawo yokuhlala efanelekileyo, itekhnoloji yolawulo lwexesha lokwenyani, njl. njl. indawo.Umzekelo, ngokweemfuno zenkqubo, ubume bomgqomo wezinyo emazinyweni okanye ubude bezinyo buyanda, kwaye indawo yokunxibelelana yamazinyo incinci kubude bokunxibelelana, indawo kunye nemeko yokuphambuka.
Izizathu zokuLapping
1. Ixabiso le-dentation liphantsi, ixabiso lezixhobo liphantsi, kwaye kuyacaca ukunciphisa umphumo wengxolo;
2. Isixhobo se-spiral cone ukuya emazinyweni siza kusetyenziswa, kodwa umphezulu wezinyo wevili elikhulu kunye nevili elincinci yeyona nto ingcono.
3. Emva kokuba amazinyo kunyango lobushushu begiya, iigiya ezimbini ziphantsi komnye nomnye, izixhobo ezinjalo azibhubhisi igobolondo eliqinileyo, kwaye amazinyo ayafana, aqinisekisa ubomi besixhobo;
4. Kuyo yonke inkqubo yokuhanjiswa kwemoto, isantya esiphambili semoto (ukuhanjiswa kokugqibela) ayibalulekanga emva kokusebenzisa izinyo lokugaya, kuba inkqubo yokuhambisa kwindlela yokuhambisa, njengokuhanjiswa, nakuyo yonke inkqubo yokuhambisa.Ukuchaneka kweyunithi ayiphezulu kakhulu;
5. Nangona kunye nezinto ezithunyelwa ngaphandle, unyango lokushisa lusetyenziselwa ukusebenzisa uphando kwi-lapping, kwaye iindleko zokuvelisa azikho ngaphezu kokugaya.
Ukusila:Ukuguqulwa konyango lobushushu kuyapheliswa emva kokuqina kwamazinyo, kwaye kuphuculwe ngakumbi ukuchaneka kwegiya kunye nokuphucula uburhabaxa bendawo yezinyo, kwaye kusekwe ikakhulu kwinkqubo yokusila.
Iimfuno zamazinyo eGear phambi kokuSila
1. Ibhalansi yentsimbi kufuneka ifane
Ngenxa yokuguquka emva kokucima ikhabhoni yegiya, ukuchaneka kufuneka kuwele ngamanqanaba angama-1-2, kwaye ukugaya kufuneka kulungiswe, ngoko ke ubungakanani bomda wokugcina igiya kufuneka bube yeyona nto iphezulu yokuguqula igiya emva kokucima i-carburizing.Ngokuqinisekileyo.Ngokubanzi, ulwahlulo oluphezulu lunxulumene ikakhulu nesakhono senkqubo ye-thermal yezinto, inkqubo yonyango lobushushu, ubume begiya kunye nejometri yejometri, ngoko ke imali eseleyo kufuneka ithathelwe ingqalelo ezi zinto zingasentla.
2. Isixhobo kufuneka sibe nophahla oluthile kwingcambu, kwaye kukho izizathu ezithathu:
2. 1 Ukususela kwinkqubo yokugaya, kufuneka ukuba ingcambu ethile isikwe kwingcambu ukuze idlale indima ye-blade.
2. 2 Emva kokuba igiya icinyiwe, uxinzelelo olushiyekileyo lwegiya lucinezela, oluluncedo kakhulu ekuphuculeni amandla okugoba egiya, kwaye ingcambu yokugaya iya kuguqula uxinzelelo olushiyekileyo lomphezulu ukutsala uxinzelelo, oluya kuthi. yenza izinyo levili Amandla achasene nokugoba ancitshiswa malunga ne-17-25%.
2. 3 Ukusuka kumandla okugoba kwevili, kuyafuneka ukuba ube nengcambu ethile yengcambu yegiya.Ukuba akukho ngcambu yengcambu yengcambu, inyathelo lengcambu liya kuvelisa amanyathelo, okuya kubangela ukuba kukhulu Uxinzelelo lwexinzelelo, oluchaphazela kakhulu ukukwazi ukugoba kwegiya.
3. 3 Ubude be-asymptom yegiya yangasemva
Kufuneka ibe yinde ngokwaneleyo, kuba ingcambu ihlulwe, kunokwenzeka ukwenza ubude bokugaya emva kokugaya igiya, okukhokelela ekunciphiseni ubunzima begiya, ngaloo ndlela ivelisa ukungcangcazela kunye nengxolo ngexesha lenkqubo ye-meshing. , kwaye kwakhona kunciphisa umthamo wokuthwala umthwalo wegiya.Ke ngoko, igiya lokusila kufuneka libe nomgca owaneleyo wokuqhubekela phambili wokuqinisekisa ukusebenza kakuhle kwegiya.
Izinto eziluncedo zokuSila
1. Kwizixhobo ze-spiral kunye ne-quasi-bib gears, ukucola kunokufikelela ekutshintsheni, akusekho mfuneko yokuba kusetyenziswe, kwaye iigiya zamazinyo kufuneka zisetyenziswe, ukuze ezinye iindleko zibe nokuhlawuleka;
2. Ukugaya kunokuphucula ukuchaneka kwegiya, ukuphucula ukuchaneka kokuhanjiswa, kunye ne-lapping inokunyusa kuphela ubuninzi bomhlaba wegesi;
3. Ukugaya kunokugcina iimveliso ezininzi ezingenakubhonqa, ukunciphisa ilahleko eninzi yenkunkuma;
4. Kwiintsimbi ezininzi zasekhaya, akukho mfuneko, okubangelwa ukuguqulwa okugqithisileyo emva kokunyanga ukushisa, usebenzisa inkqubo yokugaya ukulungisa le mpembelelo, kwaye amazinyo ophando akakwazi ukufezekisa le mpembelelo;
5. Abavelisi beGear abaye bazisa iteknoloji yokusila e-China baye bafumana izibonelelo ezilungileyo kakhulu zoqoqosho;Amashishini amaninzi aphambili emveliso ye-spiral cone asebenzise iinkqubo zokusila:
6. Ngokuphuculwa kokusebenza kakuhle kokugaya, ukunyuka kwebhetshi yokuvelisa, iindleko zokuvelisa ziya kuncitshiswa kakhulu
Shwankathela
Ayinakuphikiswa into yokuba ukucola kuyacotha kunokuqhwaba kwaye kubiza kakhulu kunokuqhokra.
Umzekelo, iperi cone gears kufuna oomatshini ezimbini zokusila, gear ngalinye kufuna imizuzu emibini;i-lapping nayo iyafuneka imizuzu emibini, kodwa kufuneka umatshini omnye kuphela.Ukongeza, ixabiso lokusila lomatshini wokusila liphindwe kathathu kwiindleko zomatshini wokugaya.
Nangona kunjalo, amazinga enkunkuma kunye nezikhalazo zabathengi ezifakwe kwiindawo ezithile zi-1% kuphela okanye ngaphantsi, ngelixa iimveliso ezigqithisiweyo zifikelela kwi-3-7%.Izixhobo zenkunkuma ziqulethe iindleko zazo zonke iinkqubo, kodwa zongeza iifizi zezinto eziphathekayo, ngoko ke ngokuqwalasela amaxabiso enkunkuma, ukugaya kunoqoqosho olungcono.
Kwiminyaka emihlanu edlulileyo, iindlela ezimbini zokulungisa zahluke kakhulu kwiindleko, zilungele amazinyo, kodwa namhlanje, uphando lubonisa ukuba kunye nophuhliso lobuchwepheshe besixhobo somatshini, ukuveliswa kwee-abrasives zevili lokusila, isicwangciso sokugqiba i-semi-finishing Application kunye nabaninzi. ezinye impumelelo ziye zafezwa, kwaye molars zinekamva eliqaqambileyo, nto leyo eyenza kube indlela enomtsalane kakhulu processing.
