【摘要】 本文对我院研制的CGD-721型刚性剑杆织机引纬凸轮的磨损和寿命进行研究。对失效的帆布剑杆织机接纬凸轮的表面分析表明,凸轮的失效是由于凸轮轮廓上不均匀受力而造成的不均匀磨损,致使凸轮与转子间的间隙增大,共轭精度下降,凸轮所传递的运动规律遭到破坏,引起附加动载荷产生、织机振动和噪声增大,无法正常工作。更多还原

【Abstract】 This paper dealt with the service life and wearing of the rapier-driving conjugate cams of themodel CGD-721 rigid rapier loom designed by our college.The surface analysis of the yarn-accepting rapier showed that the failure of the cams was due to the uneven wear caused by theuneven force acting on the cams’ outline.It made the cams gap irregular and the rapier movement.changed It would also cause the additional impact load producing loom vibration and noiseincrease.The loom couldn’t operate in normal way.更多还原
