SD-U1 harmonic reducer adopts the classic three-body harmonic drive structure composed of wave generator, flexible spline and rigid spline, with integrated high-precision crossed roller bearing embedded inside the reducer main body. The bearing structure can bear radial load, axial load and overturning moment synchronously, which saves customers from separately designing and assembling auxiliary support bearings, simplifies the overall mechanical structural layout of miniature precision rotating equipment, and reduces component procurement costs and assembly man-hours. With a reduction ratio of 50 to 160, the product realizes efficient deceleration and torque boosting in an ultra-thin disc-shaped overall structure, which is highly suitable for miniature automated equipment with strict overall thickness and installation space restrictions.
The prominent structural feature of this model is the front raised hollow output hub. The central through-type hollow cavity can penetrate control cables, air pressure pipelines, signal wires and transmission mandrels, effectively avoiding winding, extrusion and wear of external pipelines during forward and reverse reciprocating rotation of the rotating part, and significantly improving the long-cycle continuous operation stability of rotating equipment. The multi-tooth synchronous meshing transmission mode evenly disperses the tooth surface load, fundamentally avoids local fatigue wear and tooth breakage failure caused by single-tooth concentrated stress of traditional gear reducers, and has excellent anti-fatigue and anti-impact performance for high-frequency start-stop, positive and negative alternating rotation and instantaneous peak overload working conditions. All core transmission parts are processed from high-strength alloy steel through precision forging, quenching and tempering heat treatment and mirror ultra-precision grinding, with strong overall structural rigidity, small rotation vibration amplitude and low running noise during long-term continuous stable operation.
Standard positioning bolt holes are evenly distributed on the outer fixed flange to realize quick bolt locking connection with servo motors, small rotary indexing tables and miniature rotating actuators, reduce the difficulty of on-site coaxial calibration, and shorten the overall equipment assembly cycle. The internal closed cavity is filled with long-life high-temperature resistant composite lubricating grease to realize fully sealed maintenance-free operation under conventional working conditions, reduce the regular grease filling maintenance work of the production line, and save the later operation and maintenance cost for users. Ultra-precision machining strictly controls the backlash value, ensuring that the reducer can maintain stable repeated positioning accuracy after millions of reciprocating rotation cycles, and there will be no obvious motion accuracy attenuation caused by gear wear and assembly clearance expansion. The optimized lightweight integrated structure reduces the rotational inertia of the output end, accelerates the response speed of the servo closed-loop control system, and enhances the dynamic response flexibility and positioning precision of high-speed miniature precision automation equipment.
SD-U1 raised hollow hub harmonic reducer is a miniature high-precision core transmission component developed for lightweight automation equipment that needs central wiring layout and ultra-thin installation space. It is widely used for joint driving of lightweight collaborative robots, educational teaching robots, desktop small industrial manipulators and rotary clamping modules at the end of robotic hands. It is supporting assembled on small precision CNC rotary indexing tables, optical focusing swing adjustment mechanisms, laboratory precision testing angle turntables, miniature medical rehabilitation auxiliary robot execution ends and rotary positioning units for electronic component precision assembly.
In addition, it is applicable to rotary handling mechanisms for semiconductor micro-components, pan-tilt rotating modules for industrial inspection cameras, rotary execution axes for automatic dispensing equipment, tension adjusting parts for miniature textile winding equipment and positioning turntables for small new energy battery assembly lines. For portable intelligent detection equipment and miniature motion simulation test benches, SD-U1 harmonic reducer provides high-precision, low-inertia and stable torque transmission guarantee, fully meets the application requirements of high-frequency reciprocating swing and long-term uninterrupted stable operation of compact intelligent automation equipment.
