Description

Technical Field

[0001] This utility model relates to the field of wear-resistant steel ball technology, specifically a wave-shaped annular groove wear-resistant steel ball. Background Technology

[0002] Traditional wear-resistant steel balls typically have smooth surfaces or simple groove designs, resulting in poor material flow during grinding, which easily leads to low grinding efficiency. Furthermore, the surface of the steel balls is prone to wear, resulting in a short service life. In existing technologies, some steel balls use annular groove structures to improve material flow efficiency, but the groove design is limited and cannot adapt to the grinding needs of materials of different sizes. Moreover, materials are easily stuck in the groove, affecting the grinding effect.

[0003] Therefore, there is an urgent need for a new type of wear-resistant steel ball that can optimize the material flow path, improve grinding efficiency, and enhance wear resistance and fatigue resistance. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a wave-shaped annular groove wear-resistant steel ball, which solves the problem of improving the efficiency of wear-resistant steel balls when grinding materials. The first, second, and third annular grooves can improve the efficiency of material flow and optimize the material grinding efficiency.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a wave-shaped annular groove wear-resistant steel ball, comprising a sphere, wherein a first annular groove, a second annular groove and a third annular groove are sequentially formed on the outer surface of the sphere, the first annular groove is located in the middle of the sphere, the second annular groove is symmetrically distributed on the upper and lower sides of the first annular groove, and the third annular groove is symmetrically distributed on the upper and lower sides of the second annular groove, and the first annular groove, the second annular groove and the third annular groove are all wave-shaped structures.

[0006] Furthermore, the number of wave crests and troughs in the first annular groove is greater than that in the second annular groove, and the number of wave crests and troughs in the second annular groove is greater than that in the third annular groove.

[0007] Furthermore, multiple spacers are fixed on the sphere. The spacers are perpendicular to the first, second, and third annular grooves and penetrate through each annular groove, dividing the connected space of each annular groove into multiple independent regions.

[0008] Furthermore, the edges of the first annular groove, the second annular groove, and the third annular groove are all provided with wear-resistant edge surfaces, which are inclined at 45 degrees.

[0009] Furthermore, the wavy structure of the first, second, and third annular grooves is used to improve material flow efficiency and enhance the fatigue resistance of the sphere.

[0010] Furthermore, the spacing between the spacers is equal to prevent material from accumulating in the annular groove and to improve grinding efficiency.

[0011] This invention provides a corrugated annular groove wear-resistant steel ball. Compared with the prior art, it has the following advantages:

[0012] Beneficial effects:

[0013] This wear-resistant steel ball features a wavy annular groove. By incorporating a first, second, and third wavy annular groove, it significantly improves material flow efficiency and adapts to the grinding needs of materials of different sizes. The spacer prevents material retention and further enhances grinding uniformity. The inclined design of the wear-resistant edge surface strengthens the wear resistance of the steel ball and extends its service life. The stepped wavy structure optimizes the material impact space, improves fatigue resistance, and the overall structure is simple and highly practical. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This utility model provides a technical solution: a wave-shaped annular groove wear-resistant steel ball; specifically, it includes a ball 1, and a first annular groove 2, a second annular groove 3, and a third annular groove 4 are formed on the outer surface of the ball 1. The first annular groove 2 is located in the middle of the ball 1, the second annular groove 3 is located at the upper and lower ends of the first annular groove 2 and the spacing is equal, and the third annular groove 4 is located at the upper and lower ends of the second annular groove 3 and the spacing is equal. In this way, the efficiency of the ball 1 in driving the material flow during grinding can be improved by multiple annular grooves. The first annular groove 2, the second annular groove 3, and the third annular groove 4 can improve the flow guiding efficiency, and the first annular groove 2, the second annular groove 3, and the third annular groove 4 can increase the space for the material to impact the surface of the ball 1, thereby improving the fatigue resistance of the ball 1.

[0021] The first annular groove 2, the second annular groove 3, and the third annular groove 4 are all designed in a wave shape. The first annular groove 2 has multiple sets of wave crests and troughs. The second annular groove 3 has fewer wave crests and troughs than the first annular groove 2, and the third annular groove 4 has fewer wave crests and troughs than the second annular groove 3. This stepped design can accommodate the flow of materials of different sizes. In this way, materials of different sizes can follow the first annular groove 2, the second annular groove 3, and the third annular groove 4 during the flow, thereby improving the grinding and mixing efficiency of materials.

[0022] A spacer ring 5 is fixed on the sphere 1. The spacer ring 5 is perpendicular to the first annular groove 2, the second annular groove 3, and the third annular groove 4. There are multiple spacer rings 5 ​​with equal spacing. The spacer ring 5 passes through the first annular groove 2, the second annular groove 3, and the third annular groove 4, dividing the connected space of the first annular groove 2, the second annular groove 3, and the third annular groove 4 into multiple spaces. This not only guides the material flow but also prevents the material from staying in the first annular groove 2, the second annular groove 3, and the third annular groove 4 for too long, and prevents the material from getting stuck in the first annular groove 2, the second annular groove 3, and the third annular groove 4. This also prevents the grinding of the material from being affected by the first annular groove 2, the second annular groove 3, and the third annular groove 4.

[0023] Wear-resistant edge surfaces 6 are provided on the edges of the first annular groove 2, the second annular groove 3 and the third annular groove 4. The wear-resistant edge surfaces 6 are set at an inclination of 45 degrees, which can improve the overall wear resistance of the sphere 1 and increase its overall service life.
