Pakadali pano, njira zingapo zowerengera za helical worm drive zitha kugawidwa m'magulu anayi:

1. Zopangidwa molingana ndi zida za helical

Ma modulus wamba ndi nyongolotsi ndi ma modulus wamba, yomwe ndi njira yokhwima komanso yogwiritsidwa ntchito kwambiri.Komabe, nyongolotsiyo imapangidwa molingana ndi modulus wamba:

Choyamba, modulus yachibadwa imakhudzidwa, koma axial modulus ya nyongolotsi imanyalanyazidwa;Yataya mawonekedwe a axial modulus standard, ndipo yakhala giya ya helical yokhala ndi ngodya yazambiri ya 90 ° m'malo mwa nyongolotsi.

Chachiwiri, n'kosatheka kukonza ulusi wokhazikika wokhazikika pa lathe.Chifukwa palibe zida zosinthira pa lathe kuti musankhe.Ngati zida zosinthira sizili zolondola, ndizosavuta kuyambitsa mavuto.Panthawi imodzimodziyo, zimakhalanso zovuta kupeza magiya awiri a helical okhala ndi mphambano ya 90 °.Anthu ena anganene kuti CNC lathe itha kugwiritsidwa ntchito, yomwe ndi nkhani ina.Koma manambala ndi abwino kuposa ma decimals.

2. Orthogonal helical gear kufala ndi nyongolotsi kusunga axial muyezo modulus

Magiya a Helical amakonzedwa ndikupanga ma hobs osakhala wamba molingana ndi data ya mphutsi yanthawi zonse.Iyi ndi njira yosavuta komanso yodziwika bwino yowerengera.M'zaka za m'ma 1960, fakitale yathu idagwiritsa ntchito njira iyi pazinthu zankhondo.Komabe, awiriawiri a nyongolotsi ndi hob yosakhala wamba amakhala ndi mtengo wokwera wopangira.

3. Njira yopangira kusunga axial standard modulus ya nyongolotsi ndikusankha mawonekedwe a dzino

Cholakwika cha njira yopangira iyi chagona pakusamvetsetsa kokwanira kwa chiphunzitso cha meshing.Amakhulupilira molakwika ndi malingaliro omvera kuti mawonekedwe a dzino la magiya onse ndi mphutsi ndi 20 °.Mosasamala kanthu za ngodya ya axial komanso kuthamanga kwabwino, zikuwoneka kuti zonse 20 ° ndizofanana ndipo zimatha kukhala ndi ma meshed.Zili ngati kutenga ngodya yofanana ndi dzino la nyongolotsi yowongoka ngati njira yabwinobwino.Ili ndi lingaliro wamba komanso losokonezeka kwambiri.Kuwonongeka kwa giya ya helical ya nyongolotsi ya helical gear transmission pair mu keyway slotting machine ya Changsha Machine Tool Plant yomwe tatchula pamwambapa ndi chitsanzo cha zolakwika zomwe zimachitika chifukwa cha kapangidwe kake.

4. Njira yopangira mfundo ya gawo lolingana la malamulo

Gawo loyambira lokhazikika ndi lofanana ndi gawo loyambira lomwe Mn wa hob × π × cos α N ndi lofanana ndi gawo lokhazikika Mn1 la nyongolotsi × π × cos α n1

M'zaka za m'ma 1970, ndinalemba nkhani yakuti "mapangidwe, kukonza ndi kuyeza kwa spiral gear worm worm gear pair", ndipo ndinapereka ndondomeko iyi, yomwe imatsirizidwa ndi kufotokoza mwachidule maphunziro a magiya a helical omwe ali ndi zida zosadziwika bwino komanso makina otsekemera a keyway. zida zankhondo.

(1) Main mawerengedwe mafomula a njira yopangira potengera mfundo ya magawo ofanana

Njira yowerengera ya meshing parameter modulus ya nyongolotsi ndi zida za helical
（1）mn1=mx1cos γ 1 (Mn1 ndi nyongolotsi yachibadwa modulus)

(2) cos α n1=mn × cos α n (mn1) α N1 ndi nyongolotsi yokhazikika

(3) sin β 2j=tan γ 1 ( β 2J ndi ngodya ya helix ya makina a helical gear)

(4) Mn = mx1 (Mn ndiye modulus wamba wa helical gear hob, MX1 ndiye axial modulus of nyongolotsi)

(2) Makhalidwe a formula

Njira yopangira iyi ndi yolimba m'malingaliro komanso yosavuta powerengera.Ubwino waukulu ndikuti zizindikiro zisanu zotsatirazi zimatha kukwaniritsa zofunikira.Tsopano ndikudziwitsani pabwalo la anzanu kuti agawane nanu.

a.Mfundo mpaka muyezo Idapangidwa molingana ndi mfundo ya gawo lofanana la njira yotumizira zida zozungulira;

b.Worm imakhala ndi axial modulus ndipo imatha kupangidwa ndi lathe;

c.Chitsulo chopangira zida za helical ndi hob yamagetsi yokhala ndi gawo lokhazikika, lomwe limakwaniritsa zofunikira za chida;

d.Mukamapanga makina, mawonekedwe a helical a helical gear amafika pamlingo (wosafanananso ndi kukwera kwa nyongolotsi), yomwe imapezeka molingana ndi mfundo ya geometric involute;

e.Dzino mawonekedwe ngodya ya kutembenuza chida Machining nyongolotsi kufika muyezo.Mlingo wokhotakhota wa dzino ndi kukwera kwa nyongolotsi yochokera ku cylindrical screw γ b, γ B ndi yofanana ndi ngodya yanthawi zonse yamphamvu (20 °) ya hob yomwe imagwiritsidwa ntchito.
