Aerospace equipment typically has the following requirements for its transmission system:
High-precision positioning, zero or extremely low backlash, lightweight, high reliability, compact structure, long lifespan. And harmonic reducers transmission accuracy can reach the level of arc seconds, with backlash close to zero. under the same reduction ratio, its volume is much smaller than that of planetary reducers. With a high reduction ratio (50:1~160:1), the output torque is stable.These characteristics make it an important component of precision actuators in aerospace applications
1. Satellite antenna deployment mechanism
The antenna is folded and stored during satellite launch, and deployed after entering orbit.
2. Satellite Solar Array Drive Assembly (SADA)
Solar panels need to continuously track the sun.
The drive system usually includes: Servo motor, harmonic reducer, encoder
The high-precision and low-backlash products of PICEA MOTION harmonic drive are suitable for tracking control system for solar wing rotation drive attitude adjustment mechanism
3. Aerospace robotic arm
The joints of a robotic arm typically require: High reduction ratio, high rigidity and high positioning accuracy. The ultra-thin and cup-type harmonic reducers from PICEA MOTION Harmonic reducer are particularly suitable for shoulder joint, elbow joint, wrist joint.
4. UAV gimbal system
Military drone EO/IR electro-optical pod laser ranging system target tracking system, civilian drone surveying and mapping gimbal, inspection gimbal, security gimbal. PICEA MOTION harmonic reducer can achieve sub-degree control, high stability and anti-vibration.
5. Aircraft-borne electro-optical equipment
For example: Infrared Search and Track (IRST) airborne radar turntable electro-optical aiming system. These devices require: continuous rotation with precise tracking for minor angle adjustments
6. Rocket ground testing equipment
Satellite test platform
Attitude simulator
Environmental test equipment
Antenna test turntable
