Product Description

 

1. Definition and core functions

Harmonic joint module is a highly integrated mechatronic drive unit, composed of harmonic reducer, servo motor, encoder, torque sensor and control system, mainly used as the core motion joint of robots (especially humanoid robots and collaborative robotic arms). Its core function is to convert electrical energy into precise mechanical movements, enabling high-precision position control, torque output, and dynamic response.
 
2. Core components and technical principles

Harmonic reducer

Composition: It is composed of a wave generator, a flexible wheel and a rigid wheel, and realizes tooth meshing transmission through the elastic deformation of the flexible wheel.

Principle: The wave generator input rotates at high speed, the flexible wheel periodically deforms and engages with the rigid wheel, and outputs low-speed and high-torque movement, with a transmission ratio of 1:30 to 1:160.

Technological breakthroughs:

Ultra-thin flexible wheels: Thickness down to millimeters, life of more than 10,000 hours.

Zero backlash design: Eliminate transmission error and improve movement smoothness.

Drive and sensing systems

High-density motor: The power density of frameless torque motors is increased by 30%, supporting instantaneous overload (such as 3.5 times peak torque).

Embedded sensors: Integrated non-contact torque transducers (accuracy ± 0.5% FS) and dual encoders for fully closed-loop control.

3. Key performance advantages

High Precision:

The transmission accuracy is ±10 arc seconds (±1 arc minute for traditional RV reducers), and the repeatability accuracy is ±0.1mm.

Lightweight and compactness:

The housing is made of magnesium alloy to reduce the weight by 30% and the axial length is shortened by 13mm, making it suitable for space-constrained joints (e.g. wrists, fingers).

High reliability:

Aerospace-grade products can operate stably in extreme environments of -180°C~120°C, with a lifespan of more than 15 years (satellite applications).

Low power consumption and low noise:

The operating noise < 45 decibels (required by medical scenarios), and the power consumption is 40% lower than that of traditional solutions.
