Okwangoku, iindlela ezahlukeneyo zokubala ze-helical worm drive zingahlulwahlulwa zibe ziindidi ezine:

1. Yenzelwe ngokwezixhobo zehelical

Iimodulus eziqhelekileyo zeegiya kunye neempethu ziimodulus eziqhelekileyo, eziyindlela evuthiweyo nesetyenziswa ngakumbi. Nangona kunjalo, impethu yenziwa ngomatshini ngokwemodulus eqhelekileyo:

Okokuqala, imodulus eqhelekileyo ixhalabile, kodwa imodulus ye-axial ye-worm ayikhathalelwanga; Ilahlekelwe luphawu lwe-axial modulus standard, kwaye ibe yigiya ye-helical ene-angle ye-stagger ye-90 ° endaweni ye-worm.

Okwesibini, akunakwenzeka ukuba ucubungule umsonto oqhelekileyo we-modular ngqo kwi-lathe. Kuba akukho gear yokutshintshiselana kwi-lathe onokuyikhetha. Ukuba gear yokutshintsha ayichanekanga, kulula ukubangela iingxaki. Kwangaxeshanye, kunzima kakhulu ukufumana ii-helical gear ezimbini ezine-angle ye-intersection ye-90 °. Abanye abantu banokuthi i-CNC lathe ingasetyenziswa, nto leyo eyahlukileyo. Kodwa ii-integers zingcono kunee-decimals.

2. Ukuhanjiswa kwegiya ye-orthogonal helical kunye ne-worm egcina i-axial standard modulus

Iigiya zeHelical zicutshungulwa ngokwenza iihobhu zegiya ezingezizo ezisemgangathweni ngokwedatha yemodulus eqhelekileyo yeembungu. Le yindlela elula neqhelekileyo yokubala. Kwiminyaka yoo-1960, umzi-mveliso wethu wasebenzisa le ndlela kwiimveliso zomkhosi. Nangona kunjalo, isibini seembongu kunye nehobhu engezizo ezisemgangathweni zinexabiso eliphezulu lokuvelisa.

3. Indlela yoyilo yokugcina imodulus esemgangathweni ye-axial ye-worm kunye nokukhetha i-engile yesimo sezinyo

Ingxaki yale ndlela yoyilo ikukungaqondi ngokwaneleyo ithiyori ye-meshing. Ngokwengcamango ephosakeleyo, i-engile yesimo samazinyo kuzo zonke iigiya kunye neempethu yi-20 °. Nokuba i-engile yoxinzelelo lwe-axial kunye ne-engile yoxinzelelo oluqhelekileyo, kubonakala ngathi zonke ii-20 ° ziyafana kwaye zinokudityaniswa. Kufana nokuthatha i-engile yesimo samazinyo se-worm eqhelekileyo ethe tye njenge-engile yoxinzelelo oluqhelekileyo. Le yingcinga eqhelekileyo nedidayo kakhulu. Umonakalo kwigiya ye-helical ye-worm helical gear transmission pair kumatshini we-keyway slotting we-Changsha Machine Tool Plant ekhankanyiweyo apha ngasentla ngumzekelo oqhelekileyo weziphene zemveliso ezibangelwa ziindlela zoyilo.

4. Indlela yoyilo lomgaqo wecandelo elisisiseko somthetho olinganayo

Icandelo lesiseko eliqhelekileyo lilingana necandelo lesiseko eliqhelekileyo uMn wehobhi × π × cos α N ilingana nelungu lesiseko eliqhelekileyo uMn1 wempethu × π × cos α n1

Kwiminyaka yoo-1970, ndabhala inqaku elithi “uyilo, ukucubungula kunye nokulinganisa i-spiral gear type worm gear pair”, ndaza ndacebisa le algorithm, egqitywa ngokushwankathela izifundo zokucubungula ii-helical gears ngee-hobs zegiya ezingezizo ezisemgangathweni kunye noomatshini bokufaka ii-keyway kwiimveliso zomkhosi.

(1) Iifomula eziphambili zokubala zendlela yoyilo ezisekelwe kumgaqo wamacandelo alinganayo asisiseko

Ifomula yokubala ye-meshing parameter modulus ye-worm kunye ne-helical gear
(1）mn1=mx1cos γ 1 (Mn1 yimodyuli eqhelekileyo)

(2) i-cos α n1=mn × cos α n／mn1 (α N1 yi-engile yoxinzelelo lwesiqhelo)

（3）isono β 2j=tan γ 1（β 2J yi-engile ye-helix yokwenziwa kwegiya ye-helical)

(4) Mn=mx1 (Mn yimodulus eqhelekileyo yesitovu segiya esijikelezayo, iMX1 yimodulus ye-axial ye-worm)

(2) Iimpawu zefomula

Le ndlela yoyilo ingqongqo ngokwethiyori kwaye ilula ekubaleni. Eyona nzuzo inkulu kukuba ezi mpawu zintlanu zilandelayo zinokuhlangabezana neemfuno ezisemgangathweni. Ngoku ndiza kuzisa kwiforam abahlobo ukuze babelane nani.

a. Umgaqo uhambelana nomgangatho. Yenzelwe ngokwemigaqo yecandelo elilinganayo lesiseko sendlela yokudlulisela igiya elijikelezayo elingabandakanyekiyo;

b. I-Worm igcina i-axial modulus eqhelekileyo kwaye ingatshintshwa nge-lathe;

c. Isitovu sokucubungula igiya yehelical sisitovu segiya esinemodyuli eqhelekileyo, esihlangabezana neemfuno zomgangatho wesixhobo;

d. Xa kusenziwa i-machining, i-engile ye-helical yegiya ye-helical ifikelela kwinqanaba eliqhelekileyo (elingasalingani ne-engile ephakamayo ye-worm), efunyanwa ngokomgaqo we-geometric we-involute;

e. I-engile yesimo samazinyo yesixhobo sokujika somatshini wokulungisa i-worm ifikelela kwinqanaba eliqhelekileyo. I-engile yeprofayili yamazinyo yesixhobo sokujika yi-engile enyukayo yesikrufu esisilinda esisekelwe kwi-worm γ b， γ B ilingana ne-engile eqhelekileyo yoxinzelelo (20 °) yesitovu esisetyenzisiweyo.
