2024413 (2024405) Spiral Bevel Gear is a precision transmission component developed for electric tools. Its parameter design and multiple grinding processes can fully meet the low-noise and high-stability operation requirements of electric tools.

This gear has a pressure angle of 20°, a module of 1.75, 7 teeth, and a spiral angle of 35°/L, with a shaft diameter of 12mm, an outer diameter of the tooth part of 17.1mm, a total length of 41mm, and a single weight of 0.0344kg. Made of high-quality 20CrMnTi alloy structural steel as the base material, it is manufactured through a stringent process route including normalizing, turning, rough grinding of clamping position, gear milling, heat treatment, shot blasting, four-time outer diameter grinding, and full appearance inspection. Among them, the rough grinding of clamping position lays an accurate foundation for subsequent precision machining; heat treatment and shot blasting processes enhance the gear’s wear resistance and impact resistance; the four-time outer diameter grinding further optimizes the gear’s dimensional accuracy and surface finish, effectively reducing friction loss during transmission and ensuring the long-term and efficient operation of electric tools.
