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 Gearbox, also known as a Strain Wave Gearbox, is irreplaceable in applications requiring high precision, compact size, and low load.It is widely used in collaborative robots, servo systems, precision positioning and scanning equipment, aerospace, defense, and other high-precision systems.Thanks to its zero backlash, high reduction ratio, lightweight design, high positioning accuracy, and excellent repeatability, the harmonic drive has become an essential precision transmission solution in many advanced fields.

To meet the growing demand for higher precision in harmonic reducers from customers in CNC, humanoid robots, medical equipment, and other application fields, HONPINE has established an ultra-fine grain R&D and production center. The center plans to adopt ultra-fine grain production technology to enhance the precision and rigidity of harmonic reducers.

The FHG-II series strain wave drive features a cross roller bearing coupling structure for its wave generator, allowing for automatic fine-tuning of coaxiality. The size of the cam shaft hole can be adjusted according to the customer's motor model, with the input shaft directly fitting into the inner bore of the wave generator and connected via a flat key. It incorporates a built-in high-rigidity cross roller bearing (main bearing). Generally, it is used with the rigid wheel end fixed and the flexspline end output, or with the flexspline fixed and the rigid wheel end output as the connection method.
