A halin yanzu, ana iya rarraba hanyoyin lissafi daban-daban na tuƙin tsutsotsi na helical zuwa rukuni huɗu:

1. An tsara shi bisa ga kayan aiki na helical

Tsarin gears da tsutsotsi na yau da kullun modulus ne na yau da kullun, wanda hanya ce mai girma kuma ana amfani da ita fiye da haka. Duk da haka, ana kera tsutsotsi bisa ga tsarin al'ada:

Da farko, ana damuwa da tsarin al'ada, amma ana yin watsi da tsarin axial na tsutsa; Ya rasa halayyar daidaitaccen tsarin axial, kuma ya zama kayan haɗin helical tare da kusurwar juyawa na 90 ° maimakon tsutsa.

Na biyu, ba zai yiwu a sarrafa zaren modular da aka saba amfani da shi kai tsaye a kan lathe ba. Domin babu kayan musanya a kan lathe ɗin da za ku zaɓa. Idan kayan canjin bai yi daidai ba, yana da sauƙi a haifar da matsaloli. A lokaci guda, yana da matuƙar wahala a sami gears guda biyu masu kusurwar haɗuwa ta 90 °. Wasu mutane na iya cewa ana iya amfani da lathe na CNC, wanda wani abu ne daban. Amma lambobi sun fi decimal kyau.

2. Gilashin helical na orthogonal tare da tsutsa mai kula da daidaitaccen tsarin axial

Ana sarrafa gears ɗin Helical ta hanyar yin hobs ɗin gear marasa daidaito bisa ga bayanan modulus na tsutsa na yau da kullun. Wannan ita ce hanya mafi sauƙi kuma mafi al'ada don lissafi. A cikin shekarun 1960, masana'antarmu ta yi amfani da wannan hanyar don samfuran soja. Duk da haka, nau'ikan tsutsotsi guda biyu da hob mara daidaito suna da tsadar masana'antu mai yawa.

3. Hanyar ƙira ta kiyaye daidaitaccen tsarin tsutsa na axial da kuma zaɓar kusurwar siffar haƙori

Laifin wannan hanyar ƙira yana cikin rashin fahimtar ka'idar haɗa gefuna. Ana yi masa kuskuren yarda da cewa kusurwar siffar haƙori na dukkan gears da tsutsotsi shine 20 °. Ko da kuwa kusurwar matsin lamba ta axial da kusurwar matsin lamba ta al'ada, da alama duk 20 ° iri ɗaya ne kuma ana iya haɗa su. Kamar ɗaukar kusurwar siffar haƙori na tsutsotsi madaidaiciyar bayanin martaba na al'ada azaman kusurwar matsin lamba ta al'ada. Wannan ra'ayi ne da aka saba da shi kuma mai rikitarwa. Lalacewar gear helical na ma'aunin watsa gear helical a cikin injin ramin keyway na Changsha Machine Tool Plant da aka ambata a sama misali ne na lahani na samfura da hanyoyin ƙira suka haifar.

4. Hanyar tsara ƙa'idar sashe na tushe na doka daidai gwargwado

Sashen tushe na yau da kullun daidai yake da sashin tushe na yau da kullun Mn na hob × π × cos α N daidai yake da haɗin tushe na yau da kullun Mn1 na tsutsa × π × cos α n1

A shekarun 1970, na rubuta labarin "tsara, sarrafawa da auna nau'in kayan aikin tsutsa na nau'in kayan aiki", kuma na gabatar da wannan tsarin, wanda aka kammala ta hanyar taƙaita darussan sarrafa kayan aikin helical tare da hobs na gear marasa daidaituwa da injunan ramin keyway a cikin kayayyakin soja.

(1) Babban dabarun lissafi na hanyar ƙira bisa ga ƙa'idar daidaitattun sassan asali

Tsarin lissafi na ma'aunin ma'aunin ma'aunin tsutsa da kayan aikin helical
(1)mn1=mx1cos γ 1 (Mn1 is worm normal modules)

(2) cos α n1=mn × cos α n／mn1（ α N1 shine kusurwar matsa lamba na al'ada)

(3) sin β 2j=tan γ 1(β 2J shine kusurwar helix don injinan gear helical)

(4) Mn=mx1 (Mn shine tsarin yau da kullun na hob ɗin helical gear, MX1 shine tsarin axial na tsutsa)

(2) Sifofin dabara

Wannan hanyar ƙira tana da tsauri a ka'ida kuma tana da sauƙi a lissafi. Babban fa'idar ita ce waɗannan alamomi guda biyar za su iya cika buƙatun da aka saba. Yanzu zan gabatar da ita ga abokan dandalin tattaunawa don raba muku.

a. Ka'ida har zuwa ma'auni An tsara ta bisa ga ƙa'idar ɓangaren tushe daidai gwargwado na hanyar watsa gear mai karkace;

b. Tsutsa tana riƙe daidaitaccen tsarin axial kuma ana iya ƙera shi akan lathe;

c. Murhun da ake amfani da shi wajen sarrafa kayan aikin helical hob ne mai tsarin aiki na yau da kullun, wanda ya cika buƙatun daidaito na kayan aikin;

d. Lokacin da ake yin injin, kusurwar helical na gear helical ta kai matsayin da aka saba (ba ta kai matsayin kusurwar tsutsa mai tasowa ba), wanda aka samu bisa ga ƙa'idar lissafi mai shiga;

e. Kusurwar siffar haƙori na kayan aikin juyawa don sarrafa tsutsa ta kai matsayin da aka saba. Kusurwar bayanin haƙori na kayan aikin juyawa shine kusurwar tashi ta sukurori mai siffar silinda γ b, γ B yayi daidai da kusurwar matsin lamba ta yau da kullun (20 °) na murhun da aka yi amfani da shi.
