摘　　要：为了减小锭间摇架压力差异、提高纺纱质量,为摇架新产品研发及纺纱用户摇架选型提供参考,介绍摇架握持机构的作用及性能要求,对比分析摇架夹簧握持、塑胶块握持和自锁握持典型机构特点及性能差异,着重从摇架机构三线平行度、上罗拉胶辊两锭间压力平衡、握持可靠性、装卸便利性等对三种典型摇架机构进行探讨。指出:自锁握持型机构三线平行度好、两锭间压力稳定且差异小,对上罗拉胶辊握持可靠性高且装卸便利性好,有利于延长胶辊轴承寿命,是更为理想的上罗拉胶辊握持型式。In order to reduce the difference of cradle pressure between spindles and improve the spinning quality,and provide reference for the development of new cradle products and the selection of cradle for spinning users,the function and performance requirements of the cradle gripping mechanism are introduced.The characteristics and performance differences of typical mechanisms of cradle clip spring gripping,plastic block gripping and self-locking gripping are compared and analyzed.Three typical cradle mechanisms are mainly discussed from the three-line parallelism of cradle mechanism,the pressure balance between two spindles of top roller,the reliability of gripping and the convenience of loading and unloading.It is pointed out that the self-locking gripping mechanism has good three-line parallelism,the pressure between the two spindles is stable and the difference is small,and it has high gripping reliability for top roller and convenient loading and unloading.It is beneficial to prolong the service life of cot bearing and it is a more ideal gripping type of top roller.
