Parizvino, nzira dzakasiyana dzekuverenga dzehelical worm drive dzinogona kuiswa muzvikamu zvina:

1. Yakagadzirwa maererano nehelical gear

Iyo yakajairwa modulus yegiya nehonye ndeye yakajairwa modulus, iri nzira ine vanhu vakuru uye inoshandiswa zvakanyanya. Nekudaro, gonye rinogadzirwa zvinoenderana neyakajairwa modulus:

Kutanga, iyo yakajairika modulus ine hanya, asi iyo axial modulus yehonye inoregeredzwa; Yakarasa hunhu hweaxial modulus standard, uye yave helical giya ine stagger angle ye90 ° pachinzvimbo chehonye.

Chechipiri, hazvibviri kugadzirisa yakajairwa modular shinda zvakananga pane lathe. Nekuti hapana giya rekuchinjana pane lathe kuti iwe usarudze. Kana shanduko yegiya isina kunaka, zviri nyore kukonzera matambudziko. Panguva imwecheteyo, zvakare zvakaoma chaizvo kuwana maviri helical giya ane mharadzano kona ye90 °. Vamwe vanhu vanogona kutaura kuti CNC lathe inogona kushandiswa, inova imwe nyaya. Asi nhamba dzakakwana dziri nani pane decimals.

2. Orthogonal helical gear transmission nehonye inochengetedza axial standard modulus

Helical magiya anogadziriswa nekugadzira asiri-standard giya hobs zvinoenderana nehonye yakajairika modulus data. Iyi ndiyo nzira yakareruka uye yakajairika yekuverenga. Muma1960, fekitori yedu yakashandisa nzira iyi kune zvigadzirwa zvemauto. Nekudaro, maviri ehonye pairi uye isiri-yakajairwa hobho ine yakakwira mutengo wekugadzira.

3. Nzira yekugadzira yekuchengeta axial standard modulus yeworm uye kusarudza mazino chimiro angle.

Mhosho yeiyi nzira yekugadzira iri mukusanzwisisa kwakakwana kweiyo meshing theory. Zvinotendwa zvisizvo nekufungidzira kwekuzvibata kuti zino chimiro chekona yemagiya ese nehonye i20 °. Zvisinei neiyo axial pressure angle uye yakajairika pressure angle, zvinoita sekunge ese 20 ° akafanana uye anogona kuve meshed. Zvakangofanana nekutora zino chimiro chekona yeyakajairika profil worm seyakajairika pressure angle. Iyi ipfungwa yakajairika uye yakavhiringika zvakanyanya. Kukuvadzwa kweiyo helical giya rehonye helical giya rekutapurirana peya mune keyway slotting muchina weChangsha Machine Tool Plant yataurwa pamusoro muenzaniso wakajairwa wehurema hwechigadzirwa hunokonzerwa nenzira dzekugadzira.

4. Nzira yekugadzira yenheyo yemutemo wakaenzana chikamu chikamu

Iyo yakajairika base chikamu chakaenzana neyakajairwa base chikamu Mn yehobhu × π × cos α N yakaenzana neyakajairwa base yakabatana Mn1 yehonye × π × cos α n1

Mumakore ekuma1970, ndakanyora chinyorwa ichi "dhizaini, kugadzirisa uye kuyerwa kwespiral gear type worm gear pair", ndikaronga iyi algorithm, inopedzwa nekupfupisa zvidzidzo zvekugadzirisa magiya ehelical neasina-standard giya hobs uye keyway slotting machines. zvigadzirwa zvehondo.

(1) Main calculation formulas yenzira yekugadzira yakavakirwa pamusimboti wezvikamu zvakaenzana zvakakosha

Kuverengera fomula ye meshing parameter modulus yehonye uye helical giya
（1）mn1=mx1cos γ 1 (Mn1 is worm normal modulus)

（2）cos α n1=mn × cos α n／mn1（ α N1 isworm normal pressure angle)

（3）sin β 2j=tan γ 1（ β 2J ndiyo helix angle yehelical gear machining)

(4) Mn = mx1 (Mn ndiyo yakajairika modulus yehelical gear hob, MX1 ndiyo axial modulus yehonye)

(2) Formula maitiro

Iyi nzira yekugadzira yakasimba mudzidziso uye iri nyore mukuverenga. Kubatsira kukuru ndekwekuti zviratidzo zvishanu zvinotevera zvinogona kusangana nezvinodiwa. Zvino ini ndichazvisuma kune iyo forum shamwari kuti ndigovane newe.

a. Nheyo kusvika kune yakajairwa Yakagadzirwa zvinoenderana nemusimboti weyakaenzana base chikamu che involute spiral gear transmission nzira;

b. Worm inochengetedza yakajairika axial modulus uye inogona kugadzirwa palathe;

c. Iyo hobho yekugadzira helical giya igiya hobho ine yakajairwa module, inosangana nezvinodiwa zvekumira zvechishandiso;

d. Paunenge uchigadzira, iyo helical angle yehelical giya inosvika pachiyero (haisisiri yakaenzana nekukwira kwegonye), iyo inowanikwa maererano neinvolute geometric principle;

e. Iro zino chimiro chekona chekushandura chishandiso chekugadzira worm inosvika pachiyero. Zino profile angle yekuchinja chishandiso ikona inokwira yeworm based cylindrical screw γ b， γ B yakaenzana neyakajairwa kudzvanywa kona (20 °) yehobhu inoshandiswa.
