I tēnei wā, ka taea te whakarōpū i ngā tikanga tatau o te puku kutukutu porowhita ki ngā wāhanga e whā:

1. I hangaia kia rite ki te taputapu porowhita

Ko te modulus noa o ngā taputapu me ngā noke he modulus paerewa, he tikanga kua pakeke ake, ā, he nui ake te whakamahinga. Heoi, ka mīhinihia te noke kia rite ki te modulus noa:

Tuatahi, ko te modulus noa e pā ana, engari ko te modulus axial o te kutukutu kāore i arohia; kua ngaro te āhuatanga o te paerewa modulus axial, ā, kua huri hei taputapu helical me te koki hurihuri o te 90 ° hei utu mō te kutukutu.

Tuarua, kāore e taea te tukatuka tika i te miro modular paerewa ki runga i te mīhini hurihuri. Nā te mea kāore he taputapu whakawhiti i runga i te mīhini hurihuri hei whiriwhiri māu. Ki te kore e tika te taputapu whakawhiti, he ngāwari te raru. I taua wā anō, he tino uaua hoki te kimi i ngā taputapu porowhita e rua me te koki whakawhiti o te 90°. Tērā pea ka kī ētahi ka taea te whakamahi i te mīhini hurihuri CNC, he take kē atu tēnā. Engari he pai ake ngā tauoti i ngā tau ira.

2. Te tuku taputapu helical orthogonal me te kutukutu e pupuri ana i te modulus paerewa axial

Ka tukatukahia ngā taputapu porowhita mā te hanga i ngā oumu taputapu kore-paerewa e ai ki ngā raraunga modulus noa o te kutukutu. Koinei te tikanga māmā rawa atu, ā, ko te tikanga tino noa mō te tatau. I ngā tau 1960, i whakamahia e tā mātou wheketere tēnei tikanga mō ngā hua hōia. Heoi, he nui te utu hanga o te takirua takirua kutukutu me te oumu kore-paerewa.

3. Te tikanga hoahoa mō te pupuri i te modulus paerewa axial o te kutukutu me te whiriwhiri i te koki āhua niho

Ko te hapa o tēnei tikanga hoahoa kei te koretake o te mārama ki te ariā whatunga. E whakaponohia ana e te whakaaro whaiaro he 20° te koki āhua niho o ngā taputapu me ngā kutukutu katoa. Ahakoa te koki pēhanga tuaka me te koki pēhanga noa, te āhua nei he rite tonu ngā 20° katoa, ā, ka taea te honohono. He rite tonu ki te tango i te koki āhua niho o te kutukutu kōtaha tika noa hei koki pēhanga noa. He whakaaro noa tēnei, ā, he tino pōhēhē. Ko te kino o te taputapu porowhita o te takirua tuku taputapu porowhita kutukutu i roto i te mīhini mokowā kī o te Changsha Machine Tool Plant kua whakahuatia ake nei he tauira noa o ngā hapa hua i puta mai i ngā tikanga hoahoa.

4. Te tikanga hoahoa o te kaupapa o te wāhanga turanga ture ōrite

He ōrite te wāhanga turanga noa ki te wāhanga turanga noa Mn o te oumu × π × cos α He ōrite te N ki te hononga turanga noa Mn1 o te noke × π × cos α n1

I ngā tau 1970, i tuhia e au te tuhinga "te hoahoa, te tukatuka me te ine i te takirua taputapu kutukutu momo taputapu porowhita", ā, i whakaarohia e au tēnei raupaparorohiko, e whakaotihia ana mā te whakarāpopototanga o ngā akoranga o te tukatuka i ngā taputapu porowhita me ngā oumu taputapu kore-paerewa me ngā mīhini mokamoka kī i roto i ngā hua hōia.

(1) Ngā tātaitanga matua o te tikanga hoahoa e ahu mai ana i te kaupapa o ngā wāhanga taketake ōrite

Tātai tātaitanga o te modulus tawhā whatunga o te taputapu kutukutu me te taputapu porowhita
（1）mn1=mx1cos γ 1 (Ko te Mn1 ko te kutukutu noa)

（2）cos α n1=mn × cos α n／mn1（ α N1 he noke te koki pehanga noa)

(3) sin β 2j=tan γ 1 (ko te β 2J te koki porowhita mō te miihini taputapu porowhita)

(4) Mn=mx1 (Ko Mn te modulus noa o te oumu taputapu porowhita, ko MX1 te modulus tuaka o te kutukutu)

(2) Ngā āhuatanga tātai

He tino pakari te ariā o tēnei tikanga hoahoa, ā, he māmā hoki te tatau. Ko te painga nui ko te taea e ngā tohu e rima e whai ake nei te whakatutuki i ngā whakaritenga paerewa. Nā, ka whakaaturia atu e au ki ngā hoa o te wānanga hei whakapuaki atu ki a koutou.

a. Mātāpono tae atu ki te paerewa. He mea hanga kia rite ki te mātāpono o te wāhanga turanga ōrite o te tikanga tuku taputapu porowhita involute;

b. Ka mau tonu te paerewa o te modulus axial o te kutukutu, ā, ka taea te mīhini i runga i te mīhini hurihuri;

c. Ko te oumu mō te tukatuka i ngā taputapu porowhita he oumu taputapu me te waeine paerewa, e tutuki ana i ngā whakaritenga paerewa o te taputapu;

d. I te wā e miihinihia ana, ka eke te koki porowhita o te taputapu porowhita ki te paerewa (kāore e rite ki te koki piki o te kutukutu), ka whiwhihia i runga i te mātāpono āhuahanga involute;

e. Ka eke te koki āhua niho o te taputapu hurihuri mō te miihini i te noke ki te paerewa. Ko te koki āhua niho o te taputapu hurihuri ko te koki piki o te tīwiri porotaka e hangai ana ki te noke γb, ko γB he ōrite ki te koki pēhanga noa (20°) o te oumu e whakamahia ana.
