The utility model aims to solve the defects and provide a harmonic cross bearing with an outer ring provided with holes.
The object of the utility model is achieved by: the utility model provides a harmonic cross bearing of outer lane trompil, includes bearing inner circle and bearing outer lane, and the bearing outer lane sets up in the outside of bearing inner circle, and the bearing outer lane lateral surface is equipped with the ball hole, is equipped with the bolt that is used for sealing the ball hole in the ball hole, and the position that the bearing outer lane top surface is close to the ball hole is equipped with the patchhole, is equipped with the circle axle that is used for fixed the bolt in the patchhole, and the top surface of bolt is equipped with circle axle assorted through-hole.
In the above description, as a further aspect, the bearing outer ring and the bearing inner ring are connected by balls. The balls provide independent rotation of the bearing outer race and the bearing inner race.
In the above description, as a further scheme, the inner side of the bearing outer ring, the outer side of the bearing inner ring and one end of the bolt, which is close to the bearing, are all provided with ball grooves matched with the balls. The ball grooves are used for providing rolling spaces for the balls.
In the above description, as a further scheme, an oil seal skeleton is provided between the bearing outer ring and the bearing inner ring. The oil seal framework is used for preventing the leakage of lubricating oil.
In the above description, as a further scheme, the top surface of the bearing outer ring and the top surface of the bearing inner ring are both provided with oil inlets. The oil inlet is used for injecting lubricating oil.
In the above description, as a further scheme, the edge of the bearing outer ring and the edge of the bearing inner ring are both provided with bevel structures. The bevel structure can prevent from cutting the staff when the staff is assembled.
The beneficial effects of the utility model are as follows: through putting into the ball groove with the ball in the ball hole, reach the activity effect of bearing outer lane and bearing inner circle, the bearing outer lane has carried out spacingly with the bearing inner circle to the ball simultaneously, need not to use the ball baffle and can not appear the condition of section, has guaranteed pivoted smoothness.
