Okwangoku, iindlela ezahlukeneyo zokubala ze-helical worm drive zinokuhlelwa ngokufanelekileyo ngokweendidi ezine:

1. Yenzelwe ngokwezixhobo ze-helical

Imodyuli eqhelekileyo yeegiya kunye neentshulube ziimodyuli eziqhelekileyo, eyindlela eqolileyo ngokwentelekiso kwaye isetyenziswa ngakumbi.Nangona kunjalo, intshulube yenziwe ngokwemodulus eqhelekileyo:

Okokuqala, imodulus eqhelekileyo ixhalabile, kodwa imodyuli ye-axial yombungu ayihoywa;Iphulukene nophawu lomgangatho we-axial modulus, kwaye iye yaba yigiya ye-helical ene-engile egxadazayo ye-90 ° endaweni yombungu.

Okwesibini, akunakwenzeka ukucubungula intambo yemodyuli esemgangathweni ngokuthe ngqo kwi-lathe.Ngenxa yokuba akukho zixhobo zokutshintshiselana kwi-lathe onokuthi ukhethe.Ukuba igiya yokutshintsha ayichanekanga, kulula ukubangela iingxaki.Kwangaxeshanye, kunzima kakhulu ukufumana iigiya ezimbini ze-helical ezine-angle yokuhlangana ye-90 °.Abanye abantu banokuthi i-lathe ye-CNC ingasetyenziswa, ngomnye umcimbi.Kodwa ii-integers zingcono kunedecimals.

2. Ukuhanjiswa kwegiya ye-helical ye-Orthogonal kunye nentshulube egcina imodyuli esemgangathweni ye-axial

Iigiya ze-Helical zicutshungulwa ngokwenza iihobs zegiya ezingekho mgangathweni ngokweenkcukacha zemodulus eqhelekileyo.Le yeyona ndlela ilula neqhelekileyo yokubala.Ngeminyaka yee-1960, umzi-mveliso wethu wasebenzisa le ndlela kwiimveliso zomkhosi.Nangona kunjalo, izibini zeentshulube kunye nesitovu esingaqhelekanga zineendleko eziphezulu zokwenziwa.

3. Indlela yoyilo yokugcina imodyuli esemgangathweni ye-axial yeentshulube kunye nokukhetha i-engile yemilo yezinyo

Impazamo yale ndlela yoyilo ilele ekungaqondwani ngokwaneleyo kwethiyori ye-meshing.Kukholelwa ngempazamo ngentelekelelo ebambekayo ukuba i-engile yezinyo yazo zonke iigiya kunye neentshulube yi-20 °.Nokuba yeyiphi i-angle yoxinzelelo lwe-axial kunye ne-angle yoxinzelelo oluqhelekileyo, kubonakala ngathi zonke i-20 ° ziyafana kwaye zinokufakwa.Kufana nje nokuthatha i-engile yokumila kwezinyo lombungu weprofayili othe ngqo njengeengile yoxinzelelo eqhelekileyo.Lo ngumbono oqhelekileyo kwaye ubhideke kakhulu.Umonakalo kwi-helical gear ye-worm helical gear transmission pair kwi-keyway slotting machine ye-Changsha Machine Tool Plant ekhankanywe ngasentla ngumzekelo oqhelekileyo weziphene zemveliso ezibangelwa iindlela zokuyila.

4. Indlela yoyilo lomgaqo-siseko wecandelo lomthetho olinganayo

Icandelo lesiseko eliqhelekileyo lilingana necandelo lesiseko eliqhelekileyo Mn of hob × π × cos α N ilingana nesiseko esiqhelekileyo esidibeneyo uMn1 wombungu × π × cos α n1

Ngoo-1970s, ndabhala inqaku elithi “uyilo, ukusetyenzwa kunye nomlinganiselo weperi yegiya yohlobo lwegiya yegiya”, kwaye ndacebisa le algorithm, egqityezelwa ngoshwankathelo lwezifundo zokusetyenzwa kweegiya ze-helical ngezixhobo zegiya ezingezizo ezisemgangathweni kunye noomatshini bokutshiza bendlela engundoqo. iimveliso zomkhosi.

(1) Iifomula zokubala eziphambili zendlela yokuyila ngokusekelwe kumgaqo wamacandelo alinganayo

Ifomyula 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) i-sin β 2j=tan γ 1（ β 2J yi-engile ye-helix yomatshini we-helical gear)

(4) Mn=mx1 (I-Mn yimodyuli eqhelekileyo ye-helical gear hob, i-MX1 yi-axial modulus yombungu)

(2) Iimpawu zefomula

Le ndlela yoyilo ingqongqo kwithiyori kwaye ilula ekubaleni.Inzuzo enkulu kukuba ezi zikhombisi zilandelayo zihlanu zinokuhlangabezana neemfuno eziqhelekileyo.Ngoku ndiza kuyazisa kwiforum yabahlobo ukuba babelane nani.

a.Umgaqo ukuya kumgangatho Uyilwe ngokomgaqo wecandelo elilinganayo le-involute spiral gear transmission method;

b.Iintshulube zigcina imodyuli yeaxial esemgangathweni kwaye inokwenziwa ngoomatshini kwilathe;

c.I-hob yokucubungula i-helical gear yi-hob ye-gear kunye nemodyuli eqhelekileyo, ehlangabezana neemfuno zomgangatho wesixhobo;

d.Xa umatshini, i-angle ye-helical ye-helical gear ifikelela kumgangatho (ayisalingani nokunyuka kwe-worm), efunyenwe ngokomgaqo wejometri we-involute;

e.I-angle yokumila kwezinyo yesixhobo sokujika sokwenza i-worm ifikelele kumgangatho.I-engile yeprofayili yezinyo yesixhobo sokujika kukunyuka kwe-engile ye-worm esekelwe kwi-cylindrical screw γ b， γ B ilingana ne-engile yoxinzelelo oluqhelekileyo (20 °) ye-hob esetyenzisiweyo.
