Technical Field

[0001] The utility model relates to the technical field of ball bearings, in particular to an anti-pulling friction swing ball bearing with a limiting structure. Background Art

[0002] The spherical bearing mainly provides support through the spherical surface at the top. Most of them are divided into three parts: upper, middle and lower. They can produce displacement within a certain range, and then install the bridge pillars at the top to prevent the upper and lower structures from being too strong and breaking. In addition, this type of bearing can be used as support for highways, elevated roads and railways.

[0003] However, the previous spherical bearings can often move slightly horizontally. It is difficult to control the movement direction of the upper bearing plate only by the friction between the groove and the ball. If there is excessive wear, it is very easy to affect the restoration of the spherical bearing. Therefore, a limiting structure should be added to limit the movement of the ball crown plate.

[0004] Now, a new type of anti-pullout friction pendulum ball bearing with a limiting structure is proposed to solve the above problems. Utility Model Content
