Description

Technical Field

[0002] Gears are fundamental mechanical transmission components used in a wide variety of applications, and the gear industry is the largest among all types of mechanical parts. The gear industry has two extremes: large and small. The irreplaceable nature of small-module gears makes them key components in precision machinery, electromechanical equipment, instrumentation, aerospace equipment, timing mechanisms, and other devices. The small-module gear industry has two types of high-end products: precision small-module gears and precision transmission devices using precision small-module gears as key components, such as harmonic reducers, which are mainly used in robotics, CNC machine tools, and other fields.

[0003] To better achieve the functions of power transmission and torque delivery, the teeth of multiple gears on the same shaft must be in phase. Typically, the positioning device used for gear assembly on a press machine can only position one gear. When assembling other gears, the positioning of the previous gear needs to be disrupted, resulting in a repeated adjustment process for each gear assembly. This leads to low assembly efficiency and poor assembly consistency.

[0004] Therefore, we propose a novel positioning device for assembling small module gears. Utility Model Content
