Gear transmission is one of the most prevalent methods in mechanical engineering, boasting high efficiency, stable transmission ratios, and strong load-carrying capacity. Among its variants, parallel shaft gear transmission is tailored for scenarios where two shafts are arranged in parallel, finding

This article mainly introduces the definitions and impacts of root undercut and steps in the manufacturing of transmission gears, discusses the step problems caused by incorrect design and manufacturing of the convex angle amount of roughing tools before and after heat treatment, and provides judgme

I. Basic Concepts of Gear Accuracy: Why Accuracy is the "Lifeline" of Transmission Systems?Gear accuracy refers to the degree of conformity between the actual geometric parameters of a gear pair (such as tooth profile, tooth pitch, helix, etc.) and the ideal design parameters. This "conformity", tho

1.1 Core Components1.2 Meshing Principlea) Formation of Involute Tooth ProfileThe meshing line is a straight line: The trajectory of the meshing point of the two gears is a fixed straight line.Constant transmission ratio: Ensures the smoothness of transmission.Divisibility of center distance: Change
