The TJX60RZ Planetary Gear Reduction Motor: A Precision Drive Solution for High-End Care Beds

The TJX60RZ is a precision planetary gear reduction motor designed for high-end multifunctional care beds. With its high torque density, ultra-low operating noise, and medical-grade reliability, it has become the core power unit for modern care beds, enabling backrest elevation, leg adjustment, and overall height control. Through multi-stage planetary gear precision reduction, this motor delivers smooth, high-torque output within a compact space, providing patients with precise, comfortable, and safe power support for posture adjustment.

Project Background
With advancements in rehabilitation medicine and the aging population, care beds have evolved from basic hospital beds into comprehensive care platforms integrating treatment assistance, rehabilitation training, comfort care, and intelligent monitoring. Core functions—such as precise posture adjustment, smooth and comfortable movement, long-term reliable operation, and a quiet care environment—place near-stringent demands on drive motors. The TJX60RZ motor is a professionally optimized solution tailored for these high-end care scenarios.

Working Principle of Care Beds and the Motor's Role
Modern multifunctional care beds typically require 4–6 drive points to achieve full functionality:
1. Backrest Elevation (0–80°): Assists patients in sitting up for eating or reading.
2. Leg Flexion/Extension (0–45°): Promotes blood circulation and prevents edema.
3. Overall Height Adjustment (450–850mm): Facilitates nursing operations and patient transfer.
4. Tilting Function (±15°): Aids in sputum drainage and prevents pressure sores.
5. Seat Mode: Assists patients in transitioning out of bed.

Each function imposes unique requirements on the motor:
- Backrest/Leg Motors: Require smooth start-stop and precise angle retention.
- Lifting Motors: Demand strong power and safety self-locking.
- Tilting Motors: Need bilateral synchronization and anti-shear protection.
The TJX60RZ, with its customizable reduction ratios and torque configurations, adapts to the specific needs of each functional position.
