A Review of the Manufacturing Process and Precision Control of Watch Bevel Gears

Shengyu Li

Abstract


Spiral bevel gears are the key transmission components for the precise timing of mechanical watches, and their processing technology determines the precision and service life of timing. This passage focuses on the manufacturing technology and precision control of watch
spiral bevel gears, expounds the characteristics and selection reasons of materials such as 20AP high-carbon steel, comprehensively explores
the support requirements of key processing equipment (such as lathes, gear hobbing machines, heat treatment facilities, etc.) as well as fixtures, tools, and measuring instruments, and highlights the process flow and quality control points of the core manufacturing steps (including
precision turning of blanks, hobbing forming, heat treatment strengthening, and surface finishing), analyzes the potential mechanisms of common defects in each step and gives improvement methods.

Keywords


Bevel gear; Precision manufacturing; Gear hobbing technology; Heat treatment distortion; Precision control
