In the embodiment of the application, the outer sides of the retainer ring, which are close to the two ends of the opening section 11, are respectively provided with a widening convex part 13 widening along the radial direction of the inner base ring 12, and the outer peripheral edge of the retainer ring is also provided with two groups of weight reducing notches symmetrically distributed on the two sides of the opening section 11.

Specifically, reduce heavy breach runs through this retaining ring along the axial, it is located to subtract heavy breach corresponding widen the bellying 13 keep away from opening section 11's one side, the setting of widening bellying 13 has not only increased the intensity of the both ends department of this retaining ring, also conveniently set up auxiliary structure at both ends and make things convenient for the dismouting to this retaining ring, simple to operate.

In the embodiment of the application, the weight-reducing notch comprises a first notch 15 and a second notch 16 which are distributed at intervals, and a counterweight protruding part 14 is formed between the first notch 15 and the second notch 16. The weight reduction notch can balance the weight increased by the widening protruding portion 13, the weight balance protruding portion 14 can strengthen the rigidity of the portion of the check ring, deformation and fatigue attenuation caused by centrifugal force in the high-speed operation process are prevented, and the check ring is stable in operation and is not fallen off in the high-speed operation process, so that the check ring is safe and reliable.

In an embodiment of the application, the weight boss 14 is located in the first part 1. The product volume is small while ensuring that the mass of the first part 1 and the second part 2 is the same.

In the embodiment of the present application, preferably, the included angle between the central lines of the two counterweight protrusions 14 is 120 °, so that the mass distribution of the retainer ring is more balanced. The retainer ring functions optimally during high speed operation.

In the embodiment of the present application, the corresponding end of the widening protrusion 13 extends to the corresponding notch one 15. The stress concentration position of the retainer ring is as few as possible, the rigidity is reliable, and the retainer ring is stable in use.

Specifically, the depth of the first notch 15 is uniform, and two ends of the first notch 15 are connected with the widening boss 13 and the counterweight boss 14 through arc transition surfaces.
