本文讨论了高速电影摄影机中输片齿轮设计的某些理论问题。以电影胶片与输片齿轮啮合特性为出发点,用解析法讨论输片齿轮齿形的设计。对园弧齿形与渐开线齿形作了比较。
This article discusses some theoretical issues in the design of sprocket gears in high-speed movie cameras. Starting from the meshing characteristics between motion picture film and sprocket gear, the design of sprocket tooth profile is discussed by analytic method. On the arc and tooth involute profile made a comparison.
