一、前言凸轮在轻纺、印刷、丝绸机械中应用颇多,它是实现工业自动化的重要零件之一。随着工业发展,凸轮的应用越来越多,而且对凸轮的设计及制造精度的要求越来越高。不久前在广州举行国外纺织机械展览会上,展出的七台织机中,有六台采用了共轭凸轮打纬机构,转速在240转/分以上,织幅在160厘米以上,这种高速阔幅织机没有正确的设计与精确的加工 First, the foreword Cam in the textile, printing, silk machinery in a lot of applications, it is one of the important parts to achieve industrial automation. With the development of industry, more and more applications of the cam, and the cam design and manufacturing precision requirements are getting higher and higher. Not long ago in Guangzhou to hold foreign textile machinery exhibition, the display of seven looms, six of the use of conjugate cam beating mechanism, speed of 240 rev / min above, more than 160 cm in width, this High-speed wide loom is not the correct design and precision machining
