Mumunda we mechanical operation, thehandwheelndiyo yakakosha interface pakati pevanhu nemichina. Kungave kuri kudya kwakanaka panguva yekugadziriswa kwechishandiso chemuchina kana kutapurirana kwetorque panguva yekuvhura nekuvhara vharafu, vhiri reruoko rinoshandura manpower kuita chaiyo mutsara kana kutenderera mafambiro kuburikidza nehungwaru dhizaini dhizaini. Ichi chinoratidzika kunge chakapfava chikamu chedenderedzwa chine misimboti yakawanda yemagetsi senge giya rekufambisa, lever musimboti, friction mechanics, zvichingodaro. Chinyorwa chino chichaongorora kuti handwheel inogona sei "kunyatso kudzora mashandiro emaoko" kubva pachiyero chekugadzirwa kwemaitiro, nzira yekufambisa, mashandiro emuchina, mamiriro ekushandisa, nezvimwewo, zvakasanganiswa neindasitiri yekugadzira zvinhu{4}mechanical dhizaini{4} mainjiniya nevashandisi vemidziyo.
Zviri Mukati
1. Basic chimiro chehandwheel: dhizaini yekubatana kubva parimu kuenda kune shaft
2. Nheyo yekutumira: kutendeuka kwekufamba kubva pakutenderera kuenda kumutsara wekufamba
3. Mechanical properties: masvomhu muenzaniso wekushanda nesimba uye torque
4. Misiyano yemisimboti mune yakajairika application mamiriro
5. Mazano anokosha ekugadzira nekugadzira: yakazara nzira yekutonga kubva kune zvinhu kusvika kune yakarurama
6. Indasitiri maitiro: akangwara uye humanized tekinoroji upgrades
1. Basic chimiro chehandwheel: dhizaini yekubatana kubva parimu kuenda kune shaft
1. Rim: "yekutanga kuonana nzvimbo" yekukweshana
Rim ndiyo musimboti wekushandisa wehandwheel, uye dhizaini yayo inotevera musimboti wekuwedzera kupokana:
Yepamusoro magadzirirwo: yakajairika knurling (yakatwasuka / mambure masikirwo), convex mapoinzi, grooves. Semuenzaniso, chigadziro chemuchina handwheel chinotora 0.8mm yakadzika net texture, iyo friction coefficient inowedzera kubva 0.3 kusvika 0.6, uye slip rate inoderedzwa ne40% kana uchishanda nemaoko akanyorova;
Kusarudzwa kwedhayamita: Iyo dhayamita yeakajairwa mavhiri emaoko kazhinji 100-300mm, idiki kwazvo (<80mm) will increase the operating force, too large (>400mm) zvichatora nzvimbo. Iyo dhayamita yakakura yevharuvhu yeruoko inoda kuti vashandi vakotama kuti vashande, zvichideredza kugona ne25%.
2. Spokes/spokes: kuenzanisa pakati pesimba uye kureruka
Huwandu hwema spokes hunowanzo 3-6, ichitevera musimboti werutsigiro rwemuchina:
Triangular spokes: 3 spokes inoumba chimiro chakagadzikana, chakakodzera mamiriro ekuremedza chiedza (zvakadai sechigadzirwa chekugadzirisa handwheels);
Oval spokes: 6 spokes inoparadzira kushushikana. Iyo inorema muchina chishandiso handwheel inotora 6-yakataura dhizaini, uye torque yemutoro inowedzerwa kubva pa50N ・ m kusvika 120N ・ m, uye deformation yakaderedzwa ne30%.
