A halin yanzu, hanyoyin lissafi daban-daban na tuƙin tsutsotsi na helical za a iya karkasa su zuwa rukuni huɗu:

1. An tsara shi bisa ga kayan aikin helical

Matsalolin gears na al'ada da tsutsotsi sune ma'auni na yau da kullun, wanda shine ingantacciyar hanyar balagagge kuma ana amfani da ƙari.Koyaya, ana sarrafa tsutsa bisa ga al'ada modules:

Da farko dai, al'adar al'ada ta shafi al'ada, amma an yi watsi da yanayin axial na tsutsa;Ya rasa halayen ma'auni na axial modules, kuma ya zama kayan aiki mai ƙarfi tare da madaidaicin kusurwa na 90 ° maimakon tsutsa.

Na biyu, ba shi yiwuwa a aiwatar da madaidaicin zaren rikodi kai tsaye akan lathe.Domin babu kayan musanya akan lathe da zaku zaba.Idan kayan canji ba daidai ba ne, yana da sauƙi don haifar da matsala.A lokaci guda kuma, yana da matukar wahala a sami gears guda biyu masu helical tare da kusurwar kusurwa na 90 °.Wasu mutane na iya cewa za a iya amfani da lathe CNC, wanda wani al'amari ne.Amma lambobi sun fi ƙima.

2. Orthogonal helical gear watsa tare da tsutsa rike axial misali modulus

Ana sarrafa gears na helical ta hanyar yin hob ɗin kayan aiki marasa daidaituwa bisa ga bayanan modules na al'ada na tsutsotsi.Wannan ita ce hanya mafi sauƙi kuma mafi al'ada don lissafi.A cikin 1960s, masana'antarmu ta yi amfani da wannan hanyar don samfuran soja.Koyaya, nau'i-nau'i na tsutsa da hob ɗin da ba daidai ba suna da tsadar masana'anta.

3. Hanyar ƙira na kiyaye ma'aunin ma'auni na axial na tsutsa da kuma zaɓar kusurwar siffar hakori

Laifin wannan hanyar ƙira ya ta'allaka ne a cikin rashin isasshen fahimtar ka'idar meshing.An yi imani da kuskure ta hanyar tunanin mutum cewa kusurwar siffar hakori na duk gears da tsutsotsi shine 20 °.Ba tare da la'akari da kusurwar matsa lamba na axial da kusurwar matsa lamba na al'ada ba, da alama duk 20 ° iri ɗaya ne kuma ana iya lalata su.Yana kama da ɗaukar kusurwar siffar hakori na al'ada madaidaiciyar bayanin martaba kamar kusurwar matsi ta al'ada.Wannan ra'ayi ne na gama-gari kuma ya ruɗe.Lalacewa ga kayan aikin helgical Helital Helical Helical Helical Wistications na keyway dumbin kayan aiki na changsha na'ura da aka ambata a sama shine misali misali na lahani na samfurin lalacewa.

4. Hanyar ƙira na ka'idar daidaitaccen sashin tushe na doka

Sashin tushe na al'ada yana daidai da sashin tushe na al'ada Mn na hob × π × cos α N daidai yake da haɗin ginin tushe na yau da kullun Mn1 na tsutsa × π × cos α n1

A cikin 1970s, na rubuta labarin "tsara, sarrafawa da auna nau'in nau'in nau'in tsutsotsi na tsutsotsi", kuma na ba da shawarar wannan algorithm, wanda aka kammala ta hanyar taƙaita darussan sarrafa kayan aikin helical tare da hobs marasa daidaitattun kayan aiki da injunan slotting keyway a ciki. kayayyakin soja.

(1) Babban ƙididdigar ƙididdiga na hanyar ƙira bisa ka'idar daidaitattun sassan sassa

Ƙididdigar ƙididdiga na meshing siga modules na tsutsotsi da helical gear
(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 sarrafa kayan aikin helical)

(4) Mn=mx1 (Mn shine al'ada modules na helical gear hob, MX1 ne axial modulus na tsutsa)

(2) Halayen tsari

Wannan hanyar ƙira tana da ƙarfi a cikin ka'idar kuma mai sauƙi a cikin lissafi.Babban fa'ida shi ne cewa alamomi biyar masu zuwa zasu iya biyan daidaitattun buƙatun.Yanzu zan gabatar da shi ga abokai na dandalin don raba tare da ku.

a.Ƙa'ida har zuwa ma'auni An ƙirƙira shi bisa ga ka'idar daidaitaccen sashin tushe na hanyar watsa kayan aikin karkace;

b.Tsutsa yana kula da daidaitaccen tsarin axial kuma ana iya sarrafa shi akan lathe;

c.Hob don sarrafa kayan aikin helical shine hob ɗin gear tare da daidaitaccen tsari, wanda ya dace da daidaitattun buƙatun kayan aiki;

d.Lokacin yin injin, kusurwar helical na gear helical ya kai daidaitattun (ba ya zama daidai da kusurwar tashi na tsutsa), wanda aka samu bisa ga ka'idar geometric mara kyau;

e.Ƙaƙwalwar siffar haƙori na kayan aiki na juyawa don sarrafa tsutsa ya kai ga ma'auni.kusurwar bayanin martabar haƙori na kayan aikin juyawa shine tsayin kusurwar tsutsotsi na tushen tsutsa γ b， γ B daidai yake da kusurwar matsa lamba ta al'ada (20 °) na hob da ake amfani da shi.
