  Abstract: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.
Key Words:cradle;top roller bearing;cot;gripping;self-locking;clip spring;plastic block
