Steel, as one of the most widely used metallic materials in industry, its performance directly determines the quality and service life of products.

This article will conduct an in-depth comparison of the strength performance of these three materials in gear applications and provide references for gear selection under different working conditions.

In the realm of industrial design, a mechanical drawing is not merely an engineer’s “blueprint of thought” but also the “universal language” connecting design, manufacturing, and assembly. Among mechanical components, rolling bearings serve as the “joints” of machinery, and their representation on drawings directly impacts accuracy and production efficiency.In 1998, the China National Institute of Standardization released GB-T …
