oval flowmeterとは 意味・読み方・使い方

To provide an ideal volumetric flowmeter having a pair of helical gears using an oval pitch curve as a reference rack tooth form, and having no containment phenomenon between each tooth form, can set a tooth height rate πm/4 of a theoretical limit of a one-point continuous contact tooth form even in the case of the small number of teeth.例文帳に追加

基準ラック歯形としてオーバルピッチ曲線を用いた一対のヘリカル歯車を持ち、少ない歯数でも一点連続接触歯形の理論限界の歯高率πｍ／４を設定可能とし、歯形間の閉じ込み現象のない理想的な容積流量計を提供する。 - 特許庁
