Technical field
The utility model relates to technical field of bearings, and in particular to a kind of linear bearing of high damping stability.
Background technique
Linear bearing is a kind of linear motion system, is used cooperatively for rectilinear path and cylindrical shaft.Due to bearing ball with
Bearing outside point contact, steel ball are rolled with the smallest frictional resistance, therefore linear bearing has friction small and more stable, no
Change with bearing speed, high sensitivity, steady linear motion with high accuracy can be obtained, linear bearing consumption also has its limitation
Property, most importantly bearing impact load-carrying ability is poor, and bearing capacity is also poor, and secondly linear bearing shakes in high-speed motion
Dynamic and noise is larger, and the fast easily excellent automation type selecting of linear bearing is included.It vibrates and makes an uproar in high-speed motion based on linear bearing
Sound is larger, and antiwhip has certain influence to the stable of axis, therefore is to need to examine to the damping of linear bearing improvement
Consider.
