Yintoni iPitch Circle kwiGears?

Kwi-gear engineering, i-pitch circle eyaziwa ngokuba yi-reference circle yenye yezona ngcamango zibalulekileyo zokuchaza indlela ii-gear ezimbini ezidibanisa ngayo i-mesh kunye nokuhambisa intshukumo. Isebenza njenge-imaginative circle emele indawo yokunxibelelana esebenzayo phakathi kwee-gear zokudibana, ukuqinisekisa ukuhanjiswa kwamandla okugudileyo nokuchanekileyo.

Inkcazo kunye neNtsingiselo

Isangqa sepitshi sisangqa esicingelwayo esiqengqeleka singatyibiliki kunye nesangqa sepitshi sesinye igiya kwi-mesh. Ububanzi besi sangqa baziwa njengobubanzi bepitshi, kwaye simisela ubungakanani begiya, umlinganiselo wesantya, kunye nomgama osembindini xa idibene negiya enye.

Kukule sangqa apho:

• Ubukhulu bezinyo bulingana nendawo yezinyo,

• Umlinganiselo wesantya phakathi kweegiya uhlala ungaguquki,

• Kwaye kwenzeka intshukumo yokuqengqeleka ecocekileyo (akukho kutyibilika).

Ngokwezibalo, ububanzi bepitch (Dp) bunxulumene nemodyuli (m) kunye nenani lamazinyo (z) ngolu hlobo:

Dp = m × z

Le equation yenza isangqa sepitshi sibe sisalathiso esibalulekileyo kuzo zonke izibalo zoyilo lwegiya.

Indima kunye nokubaluleka kweSangqa sePitch

Iisangqa sepitshiichazaijiyometri kunye nomsebenziyezixhobo zonke. Ukubaluleka kwayo kungashwankathelwa ngolu hlobo lulandelayo:

Imisela umlinganiselo weGear
Umlinganiselo wobubanzi bepitch phakathi kweegiya ezimbini unika umlinganiselo wesantya senkqubo. Umzekelo, ukuba iGear A inobubanzi bepitch obuphindwe kabini kuneGear B, iGear B iya kujikeleza ngokuphindwe kabini ngokukhawuleza.
Umgama Weziko Lolawulo
Isimbuku serediyasi yesangqa sepitshi seegiya ezimbini ze-meshing simisela umgama ophakathi phakathi kweeshafti zazo—into ebalulekileyo kuyilo kunye nokulungelelaniswa kweegiya.
Isiseko soYilo lweProfayili yamazinyo
Iprofayili yamazinyo e-involute iveliswa kwisangqa esisisiseko, esithathwe kwisangqa sepitch. Ke ngoko, ichaphazela ngokuthe ngqo indlela ezisebenzisana ngayo iigiya kakuhle nangokuzolileyo.
Iqinisekisa Ukudluliselwa Kwamandla Okutyibilikayo
Xa iigiya zidibanisa imigca kwizangqa zazo zokuma, zihambisa intshukumo ngesantya esifanayo se-angular, nto leyo enciphisa ukungcangcazela, ingxolo, kunye nokuguguleka.

I-Pitch Circle kwiMveliso yeZixhobo

Kwimveliso ebonakalayo, isangqa sepitshi asinakulinganiswa ngokwasemzimbeni kuba sisalathiso esicingelwayo. Nangona kunjalo, abavelisi bezixhobo ezichanekileyo ezifana neBelon Gear basebenzisa iinkqubo zokulinganisa izixhobo ze-CNC eziphambili kunye nokuhlolwa kwe-3D ukuqinisekisa ukuba zonke izilinganiso ezinxulumene nesangqa sepitshi zigcinwa ngokuchanekileyo. Oku kuqinisekisa ukusebenza ngokuchanekileyo kwe-meshing kuzo zonke izicelo ezifanaiimotoiibhokisi zegiya, iirobhothi zemizi-mveliso, kunye noomatshini abasebenza nzima.
