Description

Technical Field

[0001] This utility model relates to the field of steel ball technology, and in particular to a corrosion-resistant and wear-resistant steel ball. Background Technology

[0002] Steel balls are spherical objects made of steel, commonly used in various mechanical equipment and tools. They have a wide range of applications, mainly in rolling bearings, grinding balls, and mechanical transmission devices. As grinding balls, they help remove defects from the surface of materials, and as rolling bearings, they ensure the smooth operation of machinery. Steel balls are an important industrial product with a wide variety of types, performance, and uses.

[0003] Chinese patent discloses a wear-resistant steel ball (authorization announcement number CN215464881U). This patented technology includes: a steel ball body with multiple annular grooves; the steel ball body comprises: a steel ball base layer, a buffer layer, and a wear-resistant reinforcing layer; the buffer layer wraps around the outer surface of the steel ball base layer; and the wear-resistant reinforcing layer is uniformly attached to the buffer layer. This wear-resistant steel ball overcomes the problems of existing wear-resistant steel balls having a simple, mostly spherical structure, resulting in low crushing and grinding efficiency, and the tendency for cracks and other damage to the steel ball surface after prolonged use, affecting subsequent grinding effects.

[0004] However, most existing steel balls achieve wear resistance by using only a single wear-resistant reinforcing layer, resulting in poor wear resistance and affecting their service life. For example, the aforementioned comparative document uses a single wear-resistant reinforcing layer. In practical applications, when the steel ball experiences excessive external friction, this single layer fails to provide adequate wear resistance, leading to damage and rendering the steel ball unusable. Therefore, those skilled in the art have provided a corrosion-resistant and wear-resistant steel ball to address the problems mentioned in the background section. Utility Model Content
