Project Background
The pharmaceutical industry demands high precision, cleanliness, and stability from automated equipment. A pharmaceutical equipment manufacturer faced the following challenges in a robotic arm project for an automated production line:
- High-precision positioning: Repeatability within ±1 arcmin
- High rigidity: Maintain stability under frequent starts/stops and high loads
- Compact space constraints: Limited installation space, requiring miniaturization
- High-temperature resistance: Continuous operation at 80°C
- Cleanroom compatibility: Compliant with ISO Class 5 standards
Solution
We customized a dedicated RV cycloidal gear reducer with modular design and high-precision manufacturing to perfectly match the joint drive requirements of the robotic arm.
Installation Method
Flange direct connection with servo motor ensures seamless integration, compact structure, and easy maintenance.
