Because the inks used in flexographic printing comply with green and environmentally friendly standards, flexographic printing has become increasingly popular in recent years as environmental awareness continues to rise. Compared with traditional printing methods, flexographic printing machines offer higher productivity and improved printing accuracy. This article summarizes HONPINE’s experience gained from supplying harmonic drive strain wave reducers to flexographic printing machine manufacturers in recent years.

The harmonic drive reducer is a high-performance reducer featuring a compact structure, large transmission ratio, light weight, minimal backlash, and high transmission accuracy. It is widely used in high-precision fields such as industrial robotics, medical equipment, aerospace, and intelligent manufacturing. As a key core component of industrial robots, its performance directly affects motion control accuracy, operational stability, and energy efficiency. The top-hat type harmonic drive reducer is developed based on the conventional harmonic drive reducer, with enhanced rigidity and extended service life.

The FHG-SJ series strain wave gearbox is engineered for high-torque and heavy-load applications, featuring compact axial dimensions compared to conventional reducers. It incorporates a top-hat style flexspline and an integrated cam wave generator, where the cam shaft bore is customizable to match specific motor models. The input shaft directly interfaces with the wave generator’s inner bore via a keyway connection. This series typically employs a fixed flexspline end and an output circular spline end configuration.

The FCG-AJ series strain wave gear is engineered for high-torque and heavy-load applications. It adopts a cup-style flexspline and an integrated cam wave generator, where the cam shaft bore can be customized to match specific motor models. The input shaft directly interfaces with the wave generator's inner bore via a keyway connection. This series typically employs a fixed circular spline end and an output flexspline end configuration.
