Nzira dzeKuvandudza Kururamisa kweShaft Gear Hobting

Iko kuveura kwekuveura kwakanyatsonaka pane yechigaro hobbing kunyatso, saka kumwe kukanganisa mukubata kunofanirwa kunyatso kudzorwa kugadzira mhando yepamusoro giya. Hobbing inowanzo shandiswa giya machine nzira. Pamushini wekukweva nemhando yepamusoro, hobho yakanaka inoshandiswa kumachina mazino egiya ne4-5 kunyatsoita. Pane yakakurumbira nhanho hobbing muchina, ine chaiyo chaiyo hob hob, chete masere chaiwo mazino anogona kugadzirwa. Kururamisa kweiyo giya shaft giya toothing ndeye 8-8-7, uye kana iyo nzira yekushandisa giya ikashandisa maburi maviri epakati uye kumeso kumeso sekutarisa kwekumisikidza, kutsauka kweiyo hobbing kunotsanangurwa, uye iko kurongeka kwemuchina kunovandudzwa. Nzira yakakosha kwazvo.

1 hobbing machining kunyatso kuongorora

Kururamisa kwemazino e shaft kunoenderana nekufamba kwekufamba, iko kudzikama, uye iko kurongeka kwekutaurirana. Iyo hobbing machining yepamusoro inoshandisa kureba kwakajairika mutsetse uye mhete dhayamita kusvetukira kune iko kufamba kwakaringana, uye inoshandisa kutonga kweiyo zino chimiro kutsauka uye hwaro hwechikamu chikanganiso kuti uwane kudzikama kwechiitiko, uye iko kurongeka kurongeka kuri inodzorwa nekutsauka kwezino. Pasi pechiso chekutsauka kwakati wandei mukuita hobho, zvikonzero zvekutsauka zvinotsanangurwa:

1.1 mhete giya radial runout kutsauka (kureva kurwadziwa kwejometri)

Iyo mhete yegiya radial runout ndeyekuti demo riri muchikamu chegiya rimwe kutendeuka, probe iri mugiya rezino kana pamazino egiya, uye kubatanidzwa kwemativi maviri nepakati pehurefu hwezino, iyo yakanyanya shanduko huwandu. yeprobe inoenderana neakisi yezino. Izvo zvakare kurwadziwa kwechidimbu kwegiya zino mhete maererano nepakati mutsara we shaft. 

Rudzi urwu rwekurwadziwa rwunokonzerwa nenyaya yekuti maburi maviri epakati emuchina wese haana kupindirana neiyo musimboti mudziyo wekudzoreredza kutenderera kwetafura kana kukanganisa kwakakurisa. Kana kuti nekuti maburi epamusoro nepamusoro akaumbwa zvakashata, nzvimbo yekubata haina kubatwa zvakanaka kuti iite kurwadziwa, saka mhete yedhayamita yemhete inofanira kubatwa kubva kumucheto wepamusoro.

1.2 Yakajairika kureba kutsauka (kureva kurwadziwa kunoshanda)

Hobbing ndiko kugadzirisa magiya nenzira yekuratidzira. Iyo giya yekufambisa cheni kubva pachishandiso kuenda kune zino blank yakabatana nekurongeka kwekufamba zvinoenderana neiyo isingadzivisike yekufambisa chiyero. Nekudaro, aya macheni ekutapurirana anoumbwa nenhevedzano yezve relay zvinhu. 

Kuvaka kwavo uye kuparadzanisa kutsauka kunofanirwa kuve kwakanangidzirwa munzira yekutapurirana kusvika kumagumo echeni yekutapurirana, chiitiko chehukama chezvisingagamuchirwe, chinokanganisa kurongeka kwemeno. Shanduko yehurefu hweiyo yakajairwa mutsara ndiyo yakanyanya kutsauka kweiyo reaction gear mazino. Kana aka kari kechipiri, kana muchina wekubikisa usina kugutsikana, muchina wekubikisa unozogadzirwa neinotenderera njanji njanji kupfeka, indexing worm vhiri uye tafura.

 Iyo denderedzwa inotungamira njanji inoumbwa neiyo bifurcated shaft. Mukuwedzera, kana zino rezino rekuparadzanisa mazino rakasimudzwa riine bumpu rakasimba kana vhiri rakarembera, kurumwa kwakanyanyisa kana kusungirirwa, izvo zvinogona kukanganisa kuchinja kwekazhinji mutsara.

1.3 Zino chimiro kutsauka kuongorora

Kutsauswa kwechimiro chezino ndicho chinhambwe chakajairika pakati peaviri cubbly (involute) profiles yedemo mudhipatimendi rakaita zino, kusanganisira iwo chaiwo mazino profiles. Mune chaiyo yekugadzirisa maitiro, hazvibviri kuwana yakakwana yakakwana involute mazino chimiro, uye inogara iine marudzi akasiyana-siyana ekutsauka, nekudaro kukanganisa kugadzikana kwekutapurirana. Denderedzwa rekutanga regiya ndiyo parameter chaiyo inosarudza involute zino chimiro. Kana iyo base denderedzwa yakatsauka panguva yehobbing process, iyo mazino mamiriro achave akarerekera zvakare.

 The base denderedzwa radius R=chiyero chekufamba kwebanga/tafura reversal rotation angle rate xcosao (ao ndiyo kona yemazino ekutanga ehobhu), chimiro chezino chinopindirana mukuita hobho chiri chechipiri kune hobhu uye zino harina chinhu Nokubatanidza mazino eiyo isingadzivisiki kumhanya reshiyo, zvinogona kuonekwa kuti kana zino Profile kutsauka kunotemerwa hobho zino Profile kutsauka, hobho unorodza unhu haina kunaka uye zino Profile kutsauka zviri nyore kuoneka.

 Panguva imwecheteyo, iyo radial runout uye axial turbulence (kureva, kutsauswa kwemudziyo) kunoitika muhobhu mumudziyo kunewo mhedzisiro pakutsauswa kwezino. Kutsauka kwakajairika kwemazino hakuna kukanganisa, kutsauka kwekona yezino (muromo wakakora kana kukora), uye kutenderera kunoitika.

Kubudikidza nekuongororwa kweiyo machining kunyatso kweiyo shaft giya kubhaiza, izvo zvinhu zvinokanganisa iwo machining kunyatso kweiyo hobho zvinowanikwa, kuitira kuti ivandudze mhando yeiyo hobbing kugadzira. 

Iyo inorema-basa yemotokari giya bhokisi inyanzvi yekugadzira chirimwa, iyo shaft giya ndiwo wakanyanya kukosha muchina mubhokisi regiya, uye kusaenzana kweiyo machining kurongeka kunokanganisa huwandu hwese hwegiya bhokisi. Parizvino, nzira yekugadzira yemazino egiya anoshandiswa nefekitari ndiyo nzira yekubikira uye yekuveura ndebvu.
