摘要
对正切机构进行了简单的数学推导,主要讨论一种常用的正切机构——"对称正切机构"中常遇到的某个参数的微小变化对转角β的影响及这结果在实际中的应用。
This paper simply deduces some maths formulas about the tangent mechanism,mainly diss- cusses the influence of swing angle β affected by slight variation of some parameters in a kind of usual tangent mechanism——'symmetry tangent mechanism'and the application of this result.
