【技术实现步骤摘要】
本技术涉及教学模拟用具
,具体地说是一种凸轮传动机构教学模拟器。
技术介绍
众所周知,凸轮机构是由凸轮,从动件和机架组成,凸轮是一个具有曲线轮廓或凹槽的构件,一般为主动件,作等速回转运动或往复直线运动。凸轮机构在应用中的基本特点在于能使从动件获得较复杂的运动规律。因为从动件的运动规律取决于凸轮轮廓曲线,所以在应用时,只要根据从动件的运动规律来设计凸轮的轮廓曲线就可以了。凸轮机构广泛应用于各种自动机械、仪器和操纵控制装置。凸轮机构之所以得到如此广泛的应用,主要是由于凸轮机构可以实现各种复杂的运动要求,而且结构简单、紧凑。具有凹槽的凸轮可使从动件传递确定的运动,为确动凸轮的一种。一般情况下凸轮是主动的,但也有从动或固定的凸轮。多数凸轮是单自由度的,但也有双自由度的劈锥凸轮。凸轮机构结构紧凑,最适用于要求从动件作间歇运动的场合。它与液压和气动的类似机构比较,运动可靠,因此在自动机床、内燃机、印刷机和纺织机中得到广泛应用。但凸轮机构易磨损,有噪声,高速凸轮的设计比较复杂,制造要求较高。所以在教学中凸轮机构的传动成了重点和难点,在教学中,从理论上讲解,他的动作抽象不好理解,凸轮传动机构模拟器很好的解决了这个问题,让学生在模拟器运动中,去理解主动件的匀速动作带动从动件运动的关系,达到快速的理解原理,完成教学任务。
