CD-U2 harmonic reducer adopts mature three-piece harmonic drive structure composed of wave generator, flexible spline and rigid spline, equipped with integrated heavy-duty support bearing, which can bear radial force, axial force and overturning torque synchronously, removing the need for independent external bearing during mechanical design and greatly simplifying the structural design difficulty of precision automation equipment. The reduction ratio is concentrated in 50 to 160, which can realize large reduction ratio torque amplification in a thin circular outline, perfectly meet the ultra-compact installation space requirements of small robotic joints and precision rotary positioning components. The central hollow through-hole design is the core highlight of this model, which allows cables, air pipelines, drive shafts and signal lines to pass through the middle cavity, effectively tidying the internal wiring layout of rotating parts, avoiding pipeline winding and abrasion during reciprocating rotation of the equipment.
The multi-tooth simultaneous meshing transmission structure disperses tooth surface load evenly, greatly enhancing the anti-fatigue performance under frequent forward and reverse switching, high-frequency start-stop and sudden impact load conditions. All core transmission parts are made of high-strength alloy steel, processed by precision CNC cutting and overall quenching heat treatment, with stable structural rigidity, small rotation vibration and low running noise during long-term continuous operation. The outer mounting flange is prefabricated with standard distribution bolt holes, which can realize fast locking assembly with servo motors, rotary indexing tables and precision actuators, shorten on-site equipment assembly and coaxial debugging time, and improve production efficiency. The internal cavity is filled with long-life high-temperature lubricating grease for fully sealed maintenance-free operation under conventional working conditions, reduce periodic lubrication maintenance frequency of automated production lines and lower later operation cost. Strict backlash control ensures that the equipment still maintains stable positioning accuracy after millions of cyclic rotations, no obvious accuracy attenuation caused by gear wear and clearance expansion. The optimized lightweight shell design reduces the rotating inertia of the moving end, speeds up the response speed of the servo control system, and improves the dynamic motion performance of intelligent equipment.
CD-U2 hollow shaft harmonic reducer is a key precision transmission component for lightweight intelligent automation equipment with wiring requirements at the rotating center. It is widely used for joint drive of lightweight collaborative robots, desktop educational robots, miniature industrial manipulators and robot end rotary clamping modules. It is also matched to precision electric rotary tables, optical focusing swing mechanisms, laboratory precision testing angle adjustment platforms, miniature medical auxiliary robot execution ends and electronic product precision assembly rotating units. Meanwhile, it is applicable to semiconductor micro-component handling rotary mechanisms, pan-tilt rotation modules for inspection cameras, automatic dispensing rotary axes, small textile winding tension adjusting parts and positioning turntables for miniature new energy battery production equipment. For portable intelligent detection equipment and small motion simulation platforms, this harmonic reducer delivers high-precision, low-inertia and stable high-torque transmission capacity, adapting to high-frequency reciprocating swing and long-time uninterrupted stable operation demands of small intelligent automation equipment.
