The extremely thin axial dimensions allow the module to be completely embedded inside the robot's linkage, rather than being an external protrusion. This not only protects the precision transmission components from external impacts but also provides ample internal space for wiring harnesses and air lines, achieving a unity of aesthetics and function in industrial design.
The input power is automatically distributed to multiple meshing points, and the stress on each tooth surface is greatly reduced, so that the rated torque that the whole machine can withstand under the same volume increases exponentially, and the peak overload capacity can reach more than 3 times the rated value.
Reduced backlash decreases the impact and collision during gear meshing, resulting in more uniform tooth surface wear. Even during long-term high-frequency reciprocating motion, the module maintains its initial low backlash level, extending its precision lifespan and significantly reducing maintenance costs.
The dual absolute encoder has a built-in multi-turn memory function, which permanently retains the position information after power failure. The absolute angle of the joint can be known instantly when the power is turned on, and the device can be restarted seamlessly.
