Quadruple-Arc Gear Design, Digital Processing and Carrying Capacity Test
Both the industrial sector and the academic study is the single-arc and double-arc gear at present, that is, tooth profile curve are composed by one or two arc. This paper propose a new arc gear —, which tooth profile curve are composed by four arcs, and gain a invent patent (patent number is 200810212732.1). Finite element analysis and tests conformed that qssuadruple-arc gear carrying capacity is more than 30% higher than double-arc gear. Tests also confirmed that quadruple-arc gears are smooth and have less noise compared with double-arc gears when running.
