SD-U2 harmonic reducer adopts a mature three-element harmonic drive structure composed of wave generator, flexspline and circular spline, with integrated heavy-duty crossed roller bearing inside the reducer body. The bearing can bear radial force, axial force and overturning torque at the same time, which cancels the need for customers to independently configure support bearings, simplifies the structural design of miniaturized precision rotating equipment, reduces the number of spare parts and assembly working hours. With a reduction ratio of 50 to 160, the product realizes deceleration and torque multiplication in an ultra-flat disc-shaped outline, which is perfectly suitable for precision automation equipment with strict overall height limitation.
Different from the boss-type hollow reducer, this model adopts a full-flat hollow output panel design. The central through hollow hole is convenient for threading cables, air pipes and transmission shafts, effectively avoiding cable pulling and wear during forward and reverse reciprocating rotation, and improving the long-term continuous operation stability of rotating mechanisms. Multi-tooth synchronous meshing averts concentrated stress damage of single-tooth transmission of traditional reducers, with strong resistance to fatigue and impact, adapting to high-frequency start-stop, forward-reverse alternating rotation and instantaneous overload impact working conditions. All core transmission components are made of high-strength alloy steel through precision forging, quenching and tempering heat treatment and ultra-precision grinding, featuring high overall rigidity, tiny rotation vibration and low running noise during long-term stable operation.
The outer fixed flange is evenly distributed with standard mounting holes for quick bolt connection with servo motors, small rotary positioning tables and miniature rotating actuators, lowering the difficulty of coaxial alignment and shortening equipment assembly cycle. The fully sealed inner cavity is filled with long-life high-temperature lubricating grease to achieve maintenance-free operation under conventional working conditions, reduce periodic refueling maintenance and save users' later operation and maintenance costs. Ultra-precision processing controls tiny backlash, ensuring stable repeated positioning accuracy after millions of rotation cycles without accuracy drop caused by gear wear and clearance increase. The ultra-flat lightweight structure reduces output end rotational inertia, speeds up the response of servo closed-loop system, and improves dynamic positioning accuracy of high-speed precision automation equipment.
SD-U2 flat hollow harmonic reducer is a miniature high-precision transmission core component for compact automation equipment requiring ultra-thin installation space and central wiring layout. It is widely applied to joint drive of lightweight collaborative robots, teaching robots, desktop small manipulators and robot end rotary clamping modules. It is matched with small precision CNC rotary indexing tables, optical focusing swing adjustment structures, laboratory precision test turntables, miniature medical auxiliary robot actuators and rotary positioning units for electronic precision assembly.
It is also applicable to rotary handling mechanisms for semiconductor micro-components, industrial detection camera pan-tilt rotating modules, rotary shafts of automatic dispensing equipment, tension adjusting components for micro winding equipment and positioning turntables for small new energy battery assembly lines. For portable intelligent detection equipment and miniature motion simulation test platforms, SD-U2 harmonic reducer delivers high-precision, low-inertia and stable torque output, meeting the demands of high-frequency reciprocating swing and long-term stable operation of ultra-thin intelligent automation equipment.
