SF/SG-U2 harmonic reducer adopts the classic three-part harmonic drive structure composed of wave generator, flexible spline and rigid spline, matched with built-in heavy-duty crossed roller bearing. The bearing structure can bear radial load, axial load and overturning moment at the same time, which saves customers from purchasing and assembling independent support bearings separately, optimizes the overall mechanical structure layout of automation equipment, reduces the number of parts and assembly man-hours. With a wide reduction ratio coverage of 30 to 160, it can realize large deceleration and high torque output in a thin and compact circular shape, which is very suitable for medium and large-sized robotic joints, heavy-duty precision rotary tables and compact servo positioning actuators with strict space limitations.
The central large-diameter hollow through-hole is a distinctive structural feature of this product. Control cables, air pipelines, hydraulic pipelines and transmission mandrels can penetrate the hollow cavity, which effectively solves the problem of pipeline winding, pulling and abrasion during positive and negative reciprocating rotation of rotating parts, greatly improving the operational stability of long-term cyclic movement equipment. The multi-tooth simultaneous meshing transmission mode makes the tooth surface stress evenly distributed, with outstanding fatigue resistance and impact resistance, can adapt to frequent forward and reverse switching, high-frequency start-stop operation and instantaneous peak overload conditions, effectively avoiding concentrated wear and tooth breakage of single-tooth meshing of traditional gear reducers. All core transmission parts are made of high-strength alloy steel, through precision forging, quenching and tempering heat treatment and mirror grinding processing, with high overall structural rigidity, small rotation vibration and low running noise during continuous heavy-load operation.
The outer mounting flange is evenly arranged with standard positioning bolt holes, which can be quickly locked and connected with servo motors, rotary indexing tables, rotary fixtures and precision executing mechanisms, simplifying on-site coaxial calibration work and shortening the equipment assembly cycle. The internal closed cavity is filled with long-life high-temperature-resistant synthetic lubricating grease to realize fully sealed maintenance-free operation under conventional working conditions, reduce regular grease injection maintenance links on the production line and reduce the later operation and maintenance cost of users. The product adopts ultra-precision backlash control technology. After millions of reciprocating rotation cycles, the repeated positioning accuracy can remain stable, and there will be no obvious accuracy attenuation caused by gear wear and clearance increase. The optimized structural balance design reduces the rotational inertia of the output end, accelerates the response speed of the servo closed-loop system, and improves the dynamic motion performance of high-speed precision automation equipment.
SF/SG-U2 hollow shaft harmonic reducer is a high-load precision transmission core component for medium and large intelligent automation equipment requiring central wiring layout. It is widely used in medium-sized articulated industrial robot joints, heavy-duty collaborative robot rotating joints, robot multi-degree-of-freedom rotary wrists and end effector rotary modules. It is also matched with heavy-duty CNC rotary indexing tables, large optical detection deflection platforms, aerospace precision steering actuators, medical rehabilitation robot main drive joints and new energy equipment precision rotating positioning frames.
In addition, it is applicable to automated welding positioning turntables, lithium battery pole piece winding tension control mechanisms, large electronic product assembly rotary fixtures, semiconductor handling large-angle rotating platforms and intelligent logistics heavy-duty rotary sorting mechanisms. For industrial testing multi-angle simulation turntables and precision hydraulic servo rotating execution components, SF/SG-U2 harmonic reducer provides high-rigidity, high-torque and high-precision transmission support, meets the long-term stable operation requirements of medium-load intelligent equipment, and realizes high-precision motion control and flexible action switching of intelligent production equipment.
