[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] See also Figure 1-4 The utility model is a corrosion-resistant thrust bearing, comprising a bearing body 1, wherein the bearing body 1 comprises a bearing plate 11 and a bearing plate 12, a groove 18 movably arranged inside the bearing plate 11 and the bearing plate 12, a ball 19 movably arranged inside the groove 18, an oil injection hole 14 equidistantly penetrated and opened in the middle position of the annular surface of the bearing plate 11 and the bearing plate 12, a limiting ring 16 arranged between the bearing plate 11 and the bearing plate 12, limiting holes 17 equidistantly opened on the annular surface of the limiting ring 16, and an outer sealing ring 13 and an inner sealing ring 15 integrally arranged at the edge of the limiting ring 16.

[0025] Specifically, in the corrosion-resistant thrust bearing proposed in the present application, a limiting ring 16 is provided to limit the position of a plurality of the balls 19, and an outer sealing ring 13 and an inner sealing ring 15 integrally provided on the upper side edge are used to block the contact between the balls 19 and the outside, so as to achieve corrosion protection for the balls 19. At the same time, the lubricating oil injected into the interior of the bearing body 1 through the oil filling hole 14 is blocked by the outer sealing ring 13 and the inner sealing ring 15, and most of it is retained between the bearing plate 11 and the bearing plate 2 12, so as to provide continuous lubrication and protection for the balls 19, thereby improving the corrosion resistance of the bearing body 1 in disguised form.

[0026] Furthermore, the inner edges of the bearing plate 11 and the bearing plate 2 12 are provided with sealing grooves, and the sealing grooves cooperate to connect the outer sealing ring 13 and the inner sealing ring 15, and the sealing groove gap cooperates with the outer sealing ring 13 and the inner sealing ring 15, and the outer sealing ring 13 and the inner sealing ring 15 are metal sheet structures.

[0027] Specifically, the outer sealing ring 13 and the inner sealing ring 15 are matched with the clearance of the sealing groove so that the outer sealing ring 13 and the inner sealing ring 15 do not contact the inner wall of the sealing groove during continuous rotation, thereby avoiding friction damping between the inner wall of the sealing groove and the outer sealing ring 13 and the side of the inner sealing ring 15, reducing the loss of kinetic energy of the shaft, and also preventing the bearing body 1 from overheating due to high friction during use.

[0028] Furthermore, the limiting holes 17 formed on the annular surface of the limiting ring 16 correspond one-to-one to the balls 19 , and the oil filling holes 14 formed on the middle positions of the annular surfaces of the bearing plate 1 11 and the bearing plate 2 12 are connected to the grooves 18 .

[0029] Specifically, the limit ring 16 is used to limit the position of the ball 19. Under the limiting effect of the limit ring 16, the plurality of balls 19 maintain stable rotation. When the lubricating oil is injected through the oil filling hole 14 opened in the middle position of the annular surface of the bearing plate 11 and the bearing plate 2 12, the lubricating oil flows into the groove 18 through the oil filling hole 14. As the ball 19 continues to roll in the groove 18, the ball 19 is fully contacted and lubricated with the lubricating oil.

[0030] Furthermore, the bearing plate 1 11 , the bearing plate 2 12 and the limiting ring 16 are coaxially arranged, and the inner ring radii of the bearing plate 1 11 , the bearing plate 2 12 and the limiting ring 16 are the same.

[0031] Specifically, in order to avoid misalignment of the bearing plate 1 11 , the bearing plate 2 12 and the limit ring 16 when the bearing body 1 rotates, the bearing plate 1 11 , the bearing plate 2 12 and the limit ring 16 are coaxially arranged during installation, and the inner rings have the same size, so that the contact with the external shaft is uniform, thereby improving the overall operating stability of the bearing body 1.
