Basic Cheebtsam
Lub iav thiab khib kis tau tus mob feem ntau muaj ob ntu: Ib lub iav, feem ntau yog cylindrical, nrog spur, helical, los yog ncig arc hniav; thiab khib, ib kab ncaj ntawm cov hniav tsim los mesh nrog cov iav hniav rau kev sib kis. Cov iav thiab khib nyiab yog cov khoom tseem ceeb ntawm kev sib kis, thiab lawv cov meshing tsim ua rau kev hloov pauv hloov tau.
Motion Conversion Mechanism
Nyob rau hauv ib lub iav thiab khib kis tau tus mob, muaj ib tug ntse hloov mechanism ntawm rotational thiab linear motion. Tshwj xeeb, thaum kev sib hloov ntawm lub iav tsav lub khib kom txav mus rau linearly, kev sib kis tau zoo ntawm kev sib hloov thiab kev tawm suab yog tiav. Qhov kev hloov dua siab tshiab no ua rau lub iav thiab khib sib kis tau zoo rau kev hloov pauv ntawm kev sib hloov thiab kev tawm suab.
Key Parameter Kev Sib Raug Zoo
Rau txhua lub kiv puag ncig ntawm lub iav, qhov kev ncua deb ntawm cov khib nyiab mus yog nruj me ntsis sib npaug rau qhov ncig ntawm lub iav lub suab lub voj voog. Qhov kev sib raug zoo no tuaj yeem ua lej raws li S=πmz, qhov twg S sawv cev qhov deb ntawm cov khib nyiab mus rau hauv millimeters (mm); m sawv cev rau lub module, kuj nyob rau hauv millimeters; thiab z yog tus naj npawb ntawm cov hniav ntawm lub iav. Qhov kev ncua deb ntawm cov iav thiab khib yog cuam tshuam nrog kev sib hloov ceev los ntawm cov qauv lej kom ntseeg tau tias kev sib kis tau zoo. Tsis tas li ntawd, lub khib qhov ceev v yog ze ze rau lub iav qhov kev sib hloov ceev n, module m, thiab tus naj npawb ntawm cov hniav z, tshwj xeeb v=πmzn/60, qhov twg v yog millimeters ib ob (mm/s) thiab n sawv cev rau lub iav qhov kev sib hloov ceev hauv revolutions ib feeb (rpm).
