The SF/SG-A harmonic reducer adopts a mature three-component harmonic drive structure consisting of wave generator, flexible spline and rigid spline, fitted with an integrated heavy-duty crossed roller bearing inside the main body. This bearing assembly can bear radial load, axial load and overturning torque simultaneously, removing the need for customers to design and assemble independent supporting bearings separately, simplifying the overall mechanical layout of rotary automation equipment and cutting component procurement costs and assembly working hours. Covering a wide reduction ratio range from 30 to 160, the product achieves efficient speed reduction and high torque amplification within a compact stepped cylindrical structure, perfectly adapting to medium and heavy-load precision transmission scenarios with strict axial and radial space limitations.
The dual-flange structural design brings excellent installation flexibility: the rear flange is used for fixed connection with servo motors and power sources, while the front output flange matches actuators, swing arms and positioning fixtures. The central hollow keyway output shaft not only reserves a channel for wiring and pipeline penetration but also realizes torque transmission through key connection, featuring large contact area, outstanding torsional shear resistance and stable output under alternating positive and negative torque impact. The multi-tooth synchronous meshing transmission structure averts concentrated stress on single gear teeth of traditional reducers, delivering excellent fatigue resistance and shock resistance for frequent start-stop motion, reciprocating rotation and instantaneous peak overload working conditions. All core transmission components are forged from high-strength alloy steel, processed via quenching & tempering heat treatment and ultra-precision grinding, boasting remarkable overall structural rigidity, low vibration and low running noise during long-duration continuous heavy-load operation.
Standard positioning bolt holes are evenly distributed on both front and rear flanges for quick locking assembly, greatly shortening equipment coaxial alignment and assembly cycle. The fully sealed inner cavity is filled with long-life high-temperature resistant lubricating grease to realize maintenance-free operation under conventional working conditions, reducing regular lubrication maintenance on production lines and lowering long-term operation and maintenance expenses. Precision machining controls ultra-small backlash, ensuring stable repeated positioning accuracy after millions of cyclic rotations without obvious precision degradation caused by gear abrasion and clearance expansion. Optimized rotor dynamic balance design reduces rotational inertia of the output end, accelerating the response speed of the servo closed-loop control system and improving dynamic positioning performance for high-speed precision automation equipment.
SF/SG-A dual-flange hollow shaft harmonic reducer is a high-torque precision transmission core component for medium and heavy-load automation equipment requiring double-flange fixed installation and hollow shaft layout. It is widely deployed for joint driving of medium-sized industrial robots, swing joints of heavy-duty collaborative robots, rotary wrist modules of robotic end effectors and rotary driving units of mechanical clamping fixtures. It is perfectly matched with heavy-duty CNC rotary indexing tables, workpiece machining positioning turntables, industrial swing bending mechanisms, aerospace steering execution components and main drive joints of large medical rehabilitation robots.
Besides the above scenarios, it is applicable to automatic welding positioners, tension drive shafts of new energy winding equipment, rotary positioning fixtures for large workpieces, multi-angle simulation turntables for precision testing equipment and rotary steering mechanisms for intelligent handling equipment. For heavy-load swing execution parts and servo rotary actuators of automated production lines, the SF/SG-A harmonic reducer provides high-rigidity, high-overload and high-precision transmission guarantee, meeting the long-term stable operation requirements of medium and heavy-load intelligent equipment and realizing high-precision angle positioning and steady torque output for automated production equipment.
