2024351 Finished Product

This 2024351 finished helical gear is a precision transmission component specially designed for power tools, classified as a helical gear type. Its core technical parameters are precisely matched to the power transmission requirements of power tools: pressure angle of 20°, module of 1.25, number of teeth of 41, helix angle of 5°/R, inner diameter of 16mm, addendum circle diameter of 53.45mm, total length of 10mm, and a unit weight of 0.0962kg. It features a compact structure while balancing transmission efficiency and durability.

The gear is made of 20CrMnTi alloy structural steel, a material with excellent hardenability, wear resistance and impact resistance, which can fully adapt to the high-frequency and high-load operating conditions of power tools. The manufacturing process complies with strict precision machining standards: normalizing pretreatment → turning → hobbing → heat treatment strengthening → shot blasting → reaming → full appearance inspection. Among these processes, heat treatment improves the surface hardness and core toughness of the gear teeth; shot blasting eliminates tooth surface stress and optimizes surface finish; the reaming process ensures assembly dimensional accuracy; and the final full inspection guarantees zero defects in product appearance and dimensions, fully meeting the requirements for the stable operation of power tools.
