Composite qhia tuav (ntxiv categorized rau hauv):
a: Laminated qhia tuav; cov no yog tsim los ntawm welding los yog bonding peb steel daim hlau ua ke. Qee tus muaj lub qhov ntswg sprocket, thaum lwm tus tsis muaj.
b: Hloov tau - qhov ntswg qhia tuav; lub cev tseem ceeb yog tshuab los ntawm ib daim hlau, thaum lub qhov ntswg ntu - txuas los ntawm riveting lossis vuam - yog hloov tau.
Raws li kev tsim kho, hom muaj xws li peb -daim sprocket- lub qhov ntswg tuav, cov khoom siv nrog lub qhov ntswg sib xyaw, cov khoom tuav nrog cov khoom tsim- hauv kev poob siab, thiab cov khoom tuav nrog cov lus qhia alloy.
Khoom qhia tuav
Cov tuav no yog machined los ntawm ib daim hlau, nrog rau hnav- cov khoom siv alloy welded rau ntawm lub qhov ntswg; yog li ntawd, lawv qee zaum raug xa mus rau hauv kev lag luam li "alloy bars."
Ntxiv nrog rau kev tsim kho, cov ntawv qhia tuaj yeem raug cais los ntawm cov ntsiab lus tseem ceeb, feem ntau txiav ntev (piv txwv li, 16 ntiv tes, 20 ntiv tes), saw saw pitch (xws li, 0.325 ntiv tes, 3/8 ntiv tes), thiab qhov dav dav (xws li 0.050 ntiv tes, 0.063 ntiv tes).
