[0004] The utility model provides a high-stability bearing, comprising a split bearing outer ring, a double retainer, a double-row plurality of balls and a bearing inner ring, the split bearing outer ring comprising an upper bearing outer ring and a lower bearing outer ring, the double retainer comprising an upper retainer and a lower retainer, the upper bearing outer ring is embedded in the lower bearing outer ring, the upper bearing outer ring is provided with threaded holes and grooves, the lower bearing outer ring is provided with countersunk holes and grooves, the bearing inner ring is provided with grooves corresponding to the bearing outer ring, the balls are filled in the grooves between the split bearing outer ring and the bearing inner ring, the balls are connected to the bearing inner and outer rings by contact rolling, the upper and lower retainers are respectively sleeved on the outer side surfaces of the balls to limit the rolling of the balls within a certain range, thereby ensuring the stability of the bearing.

[0005] Furthermore, the outer ring and inner ring of the split bearing are both made of 316Ti forgings, the balls are made of 316 material, and the double cages are made of Teflon material.

[0006] Furthermore, the inner walls of the upper bearing outer ring and the lower bearing outer ring are both provided with grooves in the same direction so that the directions of the unidirectional axial forces are consistent.

[0007] Furthermore, the upper bearing outer ring is connected to the lower bearing outer ring by screws, and cooperates with the bearing inner ring boss to limit the inner and outer rings to prevent them from falling off.

[0008] Furthermore, the inner ring of the bearing is provided with grooves in the same direction, which are opposite to the grooves on the inner walls of the upper bearing outer ring and the lower bearing outer ring.

[0009] Compared with the prior art, the utility model has the following beneficial effects: the utility model adopts a reasonable structural design, improves the structure of the inner and outer rings of the bearing and the ball, and changes the original bearing steel material to stainless steel, so as to improve the reliability and safety problems caused by the corrosion resistance and shortened bearing life during long-term contact with the dye solution.

DETAILED DESCRIPTION

[0015] In order to more clearly understand the present invention, the specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0016] like Figure 1-4 As shown, a high-stability bearing described in the utility model includes a split bearing outer ring (upper bearing outer ring 7, lower bearing outer ring 2), the inner walls of the lower bearing outer ring 2 and the upper bearing outer ring 7 both have an open concave surface, and are provided with a first groove 14 and a second groove 10 in the same direction that match the ball 4, effectively limiting the arbitrary sliding of the ball 4. In addition, the outer wall of the upper bearing outer ring 7 is provided with an assembly boss 12 that matches the open concave surface of the lower bearing outer ring 2, and the threaded hole 11 of the upper bearing outer ring 7 is connected to the countersunk hole 8 of the lower bearing outer ring 2 by a 316 hexagon socket screw 1.

[0017] The outer wall of the bearing inner ring 5 is provided with a third groove 16 and a fourth groove 18 corresponding to the split bearing outer ring and matching the ball 4. A third limiting boss 17 and a fourth limiting boss 19 are also provided in the middle of the bearing inner ring 5, which cooperate with the 304 hexagon socket screw 1 to prevent the inner ring from sliding out toward the lower bearing outer ring 2 and the inner wall opening concave surface 15 of the upper bearing outer ring 7.

[0018] The high stability bearing also includes a double special-shaped cage (upper cage 6, lower cage 3), the upper cage 6 is sleeved on the outside of the ball 4 sequence where the upper bearing outer ring 7 is located, and the lower cage 3 is sleeved on the outside of the ball 4 sequence where the lower bearing outer ring 2 is located. To maintain the movement of the balls within a certain range. The outer ring of the split bearing and the inner ring 5 of the bearing are evenly distributed as a contact rolling connection with a number of balls 4.

[0019] The working principle of the utility model is as follows: In this embodiment, the upper bearing outer ring 7, the lower bearing outer ring 2 and the bearing inner ring 5 are all made of 316Ti forgings, and the balls are made of 316 material, which is corrosion-resistant and rust-resistant, and can be used in high-temperature environments in contact with dye liquid. At the same time, when they rotate relatively, under the opposite forces of the second groove 10, the first groove 14 of the bearing outer ring and the third groove 16, the fourth groove 18 of the bearing inner ring, the double-row balls 4 are subjected to force together, which increases the wear resistance of the bearing and extends the bearing life.

[0020] The technical solution described in the utility model is not limited to the above-mentioned specific implementation mode. Without departing from the principle and spirit of the utility model, various changes and modifications can be made to the utility model, or some of the features therein can be replaced, all of which are within the technical solution protected by this patent.
