Description

Technical Field

[0001] This utility model belongs to the field of rubber ring technology, and in particular relates to a wear-resistant rubber ring. Background Technology

[0002] Wear-resistant rubber rings are mainly used to seal and protect key components of various mechanical equipment, prevent liquid or gas leakage, and reduce friction and wear.

[0003] Currently, the structure of rubber rings on the market is relatively simple, and they are prone to surface wear after long-term use. Wear on the surface of the rubber ring will reduce its sealing effect and service life, thus requiring the replacement of the rubber ring, increasing procurement costs and wasting resources. Utility Model Content

[0004] The purpose of this invention is to provide a wear-resistant rubber ring to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A wear-resistant rubber ring includes a rubber ring body. Grooves are provided on both the upper and lower sides of the rubber ring body. An inner convex edge and an outer convex edge are formed between the groove and the rubber ring body. A plurality of mounting cavities arranged in a circumferential array are provided in the groove. A steel ball is connected to each mounting cavity by an elastic element. A circular hole for protruding the steel ball is provided on the surface of the groove above the mounting cavity. A wear-resistant protrusion is provided between every two adjacent steel balls. Steel rings are provided on both the outer and inner sidewalls of the rubber ring body.

[0006] Preferably, the steel ball and the wear-resistant protrusion are both lower than the inner and outer convex edges, the wear-resistant protrusion is lower than the steel ball, and the inner and outer convex edges are flush.

[0007] Preferably, the elastic element includes a support block, the size of which matches the size of the mounting cavity, and the support block is slidably connected to the mounting cavity vertically. The bottom of the support block is connected to the bottom inner wall of the mounting cavity by a spring. The upper surface of the support block is provided with an arc-shaped groove that matches the steel ball, and the steel ball is in rolling connection with the arc-shaped groove and the round hole.

[0008] Preferably, the inner walls on both sides of the mounting cavity are provided with closed limiting grooves at the top and bottom, and the two sides of the support block are provided with limiting blocks corresponding to the limiting grooves. The limiting blocks are slidably connected to the limiting grooves.

[0009] Preferably, an annular groove is provided in the middle part of the inner sidewall and the middle part of the outer sidewall of the rubber ring body, and the steel ring is installed in the annular groove.

[0010] Preferably, the steel ring and the annular groove are fixedly connected by adhesive.

[0011] The wear-resistant rubber ring of this utility model has the following advantages:

[0012] 1. This utility model, through the cooperation between the inner convex edge, outer convex edge, steel ball, wear-resistant protrusion and elastic element, not only achieves good sealing performance, but also, when the rubber ring body comes into contact with other objects and rubs, the steel ball can convert sliding friction into rolling friction, extending the service life of the rubber ring body. When the surface of the rubber ring body rubs, the spring adjusts the position of the steel ball through elastic deformation, so that the steel ball is always in contact with the surface of other objects, thereby greatly improving the wear resistance of the rubber ring and extending its service life.

[0013] 2. The annular groove in this invention provides a good limiting effect for the steel ring, and under the action of the steel ring, the rigidity of the rubber ring is greatly enhanced. This effectively prevents the rubber ring from deforming due to compression, and also effectively prevents the inner and outer walls of the rubber ring from being damaged due to friction.

[0024] To better understand the purpose, structure, and function of this utility model, a wear-resistant rubber ring of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] like Figure 1-3As shown, this utility model discloses a wear-resistant rubber ring, comprising a rubber ring body 1. Grooves 2 are provided on both the upper and lower sides of the rubber ring body 1. An inner convex edge 3 and an outer convex edge 4 are formed between the grooves 2 and the rubber ring body 1. Multiple mounting cavities 8 arranged in a circular array are provided within the grooves 2. A steel ball 6 is connected to each mounting cavity 8 via an elastic element. A circular hole 9 for protruding the steel ball 6 is provided on the surface of the groove 2 above the mounting cavity 8. The elastic element includes a support block 12, the size of which matches the size of the mounting cavity 8. The support block 12 is slidably connected to the mounting cavity 8, and the bottom of the support block 12 is connected to the bottom inner wall of the mounting cavity 8 via a spring 13. An arc-shaped groove matching the steel ball 6 is provided on the upper surface of the support block 12. The steel ball 6 is slidably connected to the arc-shaped groove and the circular hole 9. A wear-resistant protrusion 5 is provided between every two adjacent steel balls 6. Both the steel ball 6 and the wear-resistant protrusion 5 are lower than the inner convex edge 3 and the outer convex edge 4. The inner convex edge 3 and the outer convex edge 4 of the rubber ring are flush with each other. The inner convex edge 3 and the outer convex edge 4 will first contact the surface of the object. When the squeezing force is too large, the inner convex edge 3 and the outer convex edge 4 will shrink, so that the object will contact the surface of the steel ball 6. Since the steel ball 6 is rolled, when the rubber ring body 1 comes into contact with other objects and rubs, the steel ball 6 will change the sliding friction into rolling friction, extending the service life of the rubber ring body 1. When the surface of the rubber ring body 1 rubs, the spring 13 adjusts the position of the steel ball 6 through elastic deformation, so that the steel ball 6 is always in contact with the surface of other objects. When the surface of the steel ball 6 is squeezed to be flush with the surface of the wear-resistant protrusion 5, the object will contact the wear-resistant protrusion 5. The wear-resistant protrusion 5 is made of polytetrafluoroethylene, which has excellent chemical corrosion resistance and low coefficient of friction, thereby greatly improving the wear resistance of the rubber ring and extending its service life. The inner walls of both sides of the mounting cavity 8 are provided with closed limiting grooves 10 at the top and bottom. The two sides of the support block 12 are provided with limiting blocks 14 corresponding to the limiting grooves 10. The limiting blocks 14 and the limiting grooves 10 are slidably connected. Through the cooperation between the limiting blocks 14 and the limiting grooves 10, the support block 12 is effectively limited, making the support block 12 more stable and reliable when moving up and down.

[0026] Steel rings 7 are provided on both the outer and inner walls of the rubber ring body 1. Annular grooves 11 are provided in the middle of both the inner and outer walls of the rubber ring body 1. The steel rings 7 are installed within the annular grooves 11 and are fixedly connected to the annular grooves 11 by adhesive. The annular grooves 11 effectively limit the movement of the steel rings 7 and significantly enhance the rigidity of the rubber ring, effectively preventing deformation due to compression and damage to the inner and outer walls of the rubber ring due to friction.

[0027] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
