Product Overview

Spoked Handwheels (Spoke-type Handwheels) are precision-adjustment mechanical components in industrial equipment. Engineered from high-strength alloy/cast iron, they achieve a balance between lightweight construction and high torque transmission through their spoke structure. These components are widely used in CNC machine tools, medical devices, printing machinery, and other applications requiring manual fine-tuning, while complying with ISO 9001 international quality standards.

Core Advantages And Features

Ergonomic design

The spacing between the spokes is calculated by fluid mechanics, and the finger pressure distribution is uniform when grasping.
The edge chamfer treatment (R≥2mm) avoids scratches during operation.
Optional rubber coating (Shore A 50-60) can be selected to enhance the anti-slip performance.

Dynamic performance optimization

The 6-8 spoke layout reduces weight by 30% while maintaining torsional stiffness.
Dynamic balance accuracy ≤0.05g cm ensures vibration-free operation at high speeds.
Supports dual-mode installation (Φ12-50mm shaft diameter compatibility).

Environmental adaptability

Surface chrome plating/anodic oxidation treatment, salt spray resistance test> 500h.
Dimensional stability <0.01mm deformation under-40℃~120℃ working conditions.
Anti-static version is optional (surface resistance 10^6-10^9Ω).
