Harmony Inertia Drum Gear Harmonic Unit CSF-20-120-2UH

When the inclination angle between the shafts of the drum gear processed by this method is the angle during processing, the tooth surfaces of the inner and outer gears are in a conjugate tooth surface meshing state of meshing line contact, the transmission ratio is always 1, and no additional inertia torque is generated, and there is no interference. However, the process device used in this method has poor rigidity, so it is more difficult to process large-sized drum gears.

When using multi-coordinate CNC gear hobbing machines to process drum gears, the processing accuracy is high, but due to the expensive equipment and high processing costs, it is still rare in China.

Using CNC technology to transform ordinary gear hobbing machines to process drum gears has broad prospects. It has the advantages of high processing quality, convenient operation, strong product adaptability, low transformation cost, and short transformation cycle. Relevant literature introduces the CNC transformation technology of two-axis open-loop control, but due to the limitation of the gear hobbing machine structure, this method is not easy to implement for the drive of the hob cutter, and there are more complex processing programming and operation. The quasi-two-axis open-loop control CNC system developed by us with the Harmonaco inertial drum gear harmonic unit CSF-20-120-2UH single-chip microcomputer as the control core has been successfully used in the transformation of medium-sized gear hobbing machines to process high-quality drum gears.

In order to create a new series of drum gear coupling products with high level, meet domestic demand, and even enter the market, it is necessary to conduct in-depth research on the mechanism and design and manufacturing technology of the Harmonaco inertial drum gear harmonic unit CSF-20-120-2UH drum gear coupling.
