Mahimman Mahimmanci da Halayen Zaɓin Ƙwallon Ƙwallo

 

Bearings na ƙwalloana amfani da su sosai a cikin kayan aikin injina. Ana iya zaɓar nau'in da ya dace bisa ga aikace-aikacen. Don daidaitawa da aikace-aikace daban-daban,ƙwallo dunƙule bearingssuna bayar da nau'ikan samfura iri-iri. Hanyoyin zagayawa na ƙwallon sun haɗa da nau'in jagorar zagayawa, nau'in zagayawa, da nau'in murfin ƙarshe. Hanyoyin da zagayawa na farko sun haɗa da sanya kayan da zagayawa na farko (nau'in goro biyu, nau'in kayan da zagayawa na matsayi) da kuma sanya kayan da zagayawa na dindindin.

 

Muhimman abubuwan da za a yi don zaɓar ƙulle-ƙulle na ƙwallo:

 

1. Kayyade diamita bisa ga nauyin da aka ɗora. Sigogin aikin injin sun haɗa da ƙarfin fitarwa; idan an haɗa da na'urar rage zafi, ya kamata a yi la'akari da wannan.

 

2. Kayyade jagoran bearing na ball sukurori bisa ga saurin layi da kuma saurin juyawa. Da zarar an tantance motar, za a san saurin fitarwa. Yi la'akari da matsakaicin saurin layi da kake buƙata. Ka ninka saurin injin (raba ta hanyar rabon raguwa idan an haɗa da mai ragewa) ta hanyar jagorar bearing na ball sukurori don samun saurin layi. Wannan ƙimar ya kamata ta fi ƙimar da ake buƙata.

 

3. Kayyade tsawon maƙallin ƙwallo bisa ga ainihin buƙatun. Jimlar tsawon = bugun aiki + tsawon goro + gefen aminci + tsawon shigarwa + tsawon haɗi + gefe. Idan an ƙara ƙarin kariya, kamar hannun riga mai kariya, ya kamata a yi la'akari da rabon tsayin hannun riga (galibi 1:8, watau, matsakaicin tsayin hannun riga da aka raba da 8).

 

4. Kayyade daidaiton benayen ƙwallo bisa ga ainihin buƙatun. Ga injina na gabaɗaya, C7 ko ƙasa da haka ya isa; ga kayan aikin injin CNC, C5 ya fi yawa (ya yi daidai da ƙa'idodin gida gabaɗaya P5 ~ P4 da maki P4 ~ P3).

 

5. Kayyade nau'in goro mai ɗaukar sikirin ƙwallon bisa ga yanayin shigarwa da girman tsarin. Gyada suna da tsari da yawa, kuma tsarin goro daban-daban suna da girma daban-daban. Zaɓi bisa ga yanayin; ana ba da shawarar kada a zaɓi waɗanda suka fi ƙwarewa, domin gyara da maye gurbin na iya zama da wahala idan matsaloli suka taso.

 

6. Zaɓi kuma ƙayyade hanyar shigarwa (ƙarshen).

 

7. Yi la'akari da kayan jagora da ƙarfin shigarwa.

 

Ana ba da shawarar a zaɓi jagororin layi na ƙwallo don abubuwan jagora da ake amfani da su tare da bearings ɗin ƙwallo. Tabbas, haɗakar shafts ɗin layi da bearings ɗin layi zaɓi ne mai rahusa.

 

Halayen bearings na tallafin ƙwallo sun haɗa da:

 

1. Ingantaccen watsawa: Ingancin watsawa na tsarin watsa sikirin ƙwallo ya kai kashi 90% ~ 98%, wanda ya ninka tsarin sikirin zamiya sau 2 ~ 4 sau na tsarin sikirin zamiya na gargajiya. Saboda haka, yana iya samun babban turawa tare da ƙaramin ƙarfin juyi kuma yana iya canza motsi na layi zuwa motsi na juyawa (motsi mai juyawa).

 

2. Motsi mai santsi: Tsarin watsa sikirin ƙwallon yana amfani da motsi mai juyi na ma'auni, wanda ke haifar da ƙarancin juriya ga gogayya, babban ji, babu hira yayin farawa, kuma babu rarrafe a ƙananan gudu. Saboda haka, yana iya sarrafa micro-feed daidai.

 

3. Babban daidaito: Tsarin watsa sikirin ƙwallon yana fuskantar ƙarancin hauhawar zafin jiki yayin aiki kuma ana iya sanya shi a gaba don kawar da koma baya na axial kuma a miƙa shi kafin lokaci don rama faɗaɗa zafi, don haka cimma daidaiton matsayi mai kyau da maimaitawa.

 

4. Dorewa mai yawa: Wuraren da ke taɓa ƙwallon ƙarfe suna taurare (HRC58~63) kuma an yi musu daidai gwargwado. Tsarin zagayawa yana birgima ne kawai, tare da ƙarancin lalacewa, wanda ke haifar da tsawon rai na aiki da kuma riƙewa mai kyau. 5. Kyakkyawan Aiki tare: Saboda motsi mai santsi, amsawa mai laushi, rashin toshewa, da zamewa, tsarin tuƙin sukurori iri ɗaya da yawa na iya tuƙa wasu sassa ko na'urori iri ɗaya a lokaci guda, don cimma kyakkyawan aiki tare.

 

6. Babban Aminci: Idan aka kwatanta da sauran injunan watsawa da watsawa ta hydraulic, tsarin tuƙin ball sukurori yana da ƙarancin lalacewa kuma yana da sauƙin kulawa, yana buƙatar man shafawa gabaɗaya da hana ƙura. A cikin aikace-aikace na musamman, suna iya aiki ba tare da man shafawa ba.

 

7. Babu Taurin Baya da Taurin Kai: Tsarin tuƙin ƙwallo yana amfani da siffar ramin Gothic, yana tabbatar da cewa ya dace a haɗa ƙwallo da ramukan don sauƙin aiki. Yin amfani da kayan da suka dace yana kawar da koma-baya a axial, yana ƙara haɓaka taurin ƙwallo da rage nakasar roba tsakanin ƙwallo, goro, da sukurori, wanda ke haifar da daidaito mafi girma.

 

8. Watsawa Mai Juyawa Ba Tare Da Kulle Kai Ba: Faifan sukurin da ake juyawa suna da saurin juyawa kuma ba sa kulle kansu. Domin hana sukurin juyawa yayin da ake ɗauka, ya kamata a yi la'akari da na'urorin hana juyawa, kamar amfani da injin birki ko motar stepper, ko haɗa injin kulle kai (misali, injin gear tsutsa) a cikin tsarin watsawa; ya kamata a sanya maƙallan hanya ɗaya, maƙallan hanya biyu, ko birki a cikin goro, sukurin jagora, ko tsarin watsawa. Lokacin zaɓar maƙallin, dole ne a yi la'akari da amincinsa sosai. Hana cire maƙallan goro yana da mahimmanci a cikin maƙallan sukurin birgima, musamman maƙallan tsaye, saboda cire maƙallan goro na iya haifar da haɗari cikin sauƙi. Saboda haka, dole ne a haɗa na'urorin aminci don hana cire maƙallan goro a cikin ƙirar.
