I kēia manawa, hiki ke hoʻokaʻawale ʻia nā ʻano helu helu helical worm drive i ʻehā mau ʻāpana:
1. Hoʻolālā ʻia e like me ka mea helical gear
ʻO ka modulus maʻamau o nā gears a me nā ilo he modulus maʻamau, ʻo ia ke ʻano oʻo a hoʻohana hou aku. Eia naʻe, hana ʻia ka ilo e like me ka modulus maʻamau:
ʻO ka mea mua, pili ka modulus maʻamau, akā mālama ʻole ʻia ka modulus axial o ka ilo; Ua nalowale ka hiʻohiʻona o ka axial modulus standard, a ua lilo ia i mea helical me kahi kihi stagger o 90 ° ma kahi o kahi ilo.
ʻO ka lua, ʻaʻole hiki ke hana pololei i ke kaula modular maʻamau ma ka lathe. No ka mea, ʻaʻohe mea hoʻololi ma ka lathe āu e koho ai. Inā ʻaʻole pololei ka mea hoʻololi, maʻalahi ka pilikia. I ka manawa like, paʻakikī loa ka loaʻa ʻana o ʻelua mau mea helical me kahi kihi intersection o 90 °. E ʻōlelo paha kekahi poʻe hiki ke hoʻohana ʻia kahi lathe CNC, ʻo ia kekahi mea ʻē aʻe. Akā ʻoi aku ka maikaʻi o nā helu helu ma mua o nā decimals.
2. ʻO ka hoʻouna ʻana i nā mea helical orthogonal me ka ilo e mālama ana i ka modulus maʻamau axial
Hoʻohana ʻia nā mea hana Helical e ka hana ʻana i nā hobs mīkini maʻamau e like me ka ʻikepili modulus maʻamau. ʻO kēia ke ala maʻalahi a maʻamau no ka helu ʻana. I ka makahiki 1960, ua hoʻohana kā mākou hale hana i kēia ʻano hana no nā huahana koa. Eia nō naʻe, he kiʻekiʻe ke kumu kūʻai o nā hui ilo a me kahi hob maʻamau.
3. ʻO ke ala hoʻolālā no ka mālama ʻana i ka modulus maʻamau axial o ka ilo a me ke koho ʻana i ke kihi ʻano niho.
Aia ka hewa o kēia ʻano hoʻolālā i ka lawa ʻole o ka hoʻomaopopo ʻana i ke kumumanaʻo meshing. Ua kuhi hewa ʻia e ka noʻonoʻo kumuhana ʻo ke kihi o ke ʻano niho o nā mea āpau a me nā ilo he 20 °. ʻAʻohe o ka axial pressure angle a me ka maʻamau kaomi ʻana, me he mea lā ua like nā 20 ° āpau a hiki ke hoʻopaʻa ʻia. Ua like ia me ka lawe ʻana i ke ʻano niho o ka ilo kōpili pololei maʻamau e like me ke kihi kaomi maʻamau. He manaʻo maʻamau a huikau loa kēia. ʻO ka pōʻino i ka mea helical gear o ka worm helical gear transmission pair i ka mīkini kī kī o Changsha Machine Tool Plant i ʻōlelo ʻia ma luna nei he hiʻohiʻona maʻamau o nā hemahema huahana i hana ʻia e nā ʻano hoʻolālā.
4. ʻO ke ʻano hoʻolālā o ke kumu o ka pauku kumu kānāwai kaulike
Ua like ka pauku kumu ma'amau me ka pauku kumu ma'amau Mn o ka hob × π × cos α N ua like ia me ka hui kumu ma'amau Mn1 o ka ilo × π × cos α n1
I ka makahiki 1970, ua kākau au i ka ʻatikala "hoʻolālā, hana a me ke ana ʻana o ka spiral gear type worm gear pair", a manaʻo i kēia algorithm, i hoʻopau ʻia ma ka hōʻuluʻulu ʻana i nā haʻawina o ka hoʻoponopono ʻana i nā mea helical gears me nā hobs mīkini maʻamau a me nā mīkini slotting keyway. nā huahana kaua.
(1) Nā papa helu helu nui o ke ʻano hoʻolālā e pili ana i ke kumu o nā ʻāpana kumu like
Ka helu helu o ka meshing parameter modulus o ka ilo a me ka helical gear
(1)mn1=mx1cos γ 1 (ʻo Mn1 ka modulus maʻamau ilo)
(2)cos α n1=mn × cos α n/mn1( α N1 he ilo kaomi maʻamau angle)
(3)sin β 2j=tan γ 1)
(4) Mn=mx1 (Mn ka modulus maʻamau o ka hob helical gear, MX1 ka modulus axial o ka ilo)
(2) Nā hiʻohiʻona hoʻohālike
He koʻikoʻi kēia ʻano hoʻolālā i ke kumumanaʻo a maʻalahi i ka helu ʻana. ʻO ka pōmaikaʻi nui loa, hiki i nā mea hōʻailona ʻelima ke hoʻokō i nā koi maʻamau. I kēia manawa e hoʻolauna aku au iā ia i nā hoaaloha forum e kaʻana like me ʻoe.
a. Ke kumu a hiki i ka maʻamau Ua hoʻolālā ʻia e like me ke kumumanaʻo o ka ʻāpana kumu like o ke ʻano hoʻoili uila involute spiral;
b. Mālama ʻo Worm i ka modulus axial maʻamau a hiki ke hana ʻia ma ka lathe;
c. ʻO ka hob no ka hoʻomaʻamaʻa ʻana i nā mea helical he mea hob me ka module maʻamau, e kū ana i nā koi standardization o ka mea hana;
d. I ka hana ʻana, hiki i ka huina helical o ka helical gear i ka maʻamau (ʻaʻole like me ka piʻi ʻana o ka ilo), i loaʻa e like me ka involute geometric principle;
e. ʻO ka huina niho o ka mea hoʻohuli no ka mīkini ʻana i ka ilo hiki i ka maʻamau. ʻO ka ʻaoʻao ʻaoʻao niho o ka mea hoʻohuli ʻo ia ka piʻi ʻana o ka worm based cylindrical screw γ b, γ B ua like ia me ke kihi kaomi maʻamau (20 °) o ka hob i hoʻohana ʻia.
