Cup-Type Harmonic Drive Effectively Addresses Short Lifespan Issues of Harmonic Drivers
In industrial robots, harmonic drives are widely used in joint transmission systems due to their high precision, high torque transmission, and smooth operation. These characteristics make harmonic drives an ideal choice for applications requiring precise control and high performance, such as industrial robots, aerospace equipment, and precision instruments. To solve the problem of fatigue failure and short lifespan of the flexspline—a critical component in harmonic drives—HONPINE has designed a cup-type harmonic drive.
The Importance of the Flexspline in Harmonic Drive Construction
Harmonic transmission relies on the elastic deformation of the flexspline, making it the most stressed and fatigue-prone component. In other words, the lifespan of the flexspline determines the operational life of the harmonic drive. HONPINE optimizes structural parameters to effectively control the maximum stress on the flexspline under both no-load and loaded conditions while achieving the shortest possible barrel length. This ensures optimal performance, reduces fatigue failure risks, and extends service life.
What is a Cup-Type Harmonic Drive?
The flexspline in harmonic drives mainly comes in two shapes: cup-type and hat-type (hollow). The cup-type flexspline, resembling a cup with a recessed center, is commonly used in harmonic drives, robotics, precision machinery, and aerospace mechanisms for motion control and power transmission.
The cup-type flexspline is typically connected to other mechanical components via bolts or pins. The exact connection method depends on the harmonic drive's design and manufacturing standards, but it usually features pre-drilled holes or interfaces at the rim for secure fastening.
Advantages of Cup-Type Harmonic Drives
Also known as a double-circular-arc harmonic drive, it provides superior meshing performance and higher contact ratio between the circular spline and flexspline.
Compact and lightweight, making it ideal for industrial robots with space constraints.
HONPINE R&D analysis confirms that the double-circular-arc tooth profile outperforms traditional involute gears in stress distribution and deformation resistance.
Optimized through orthogonal testing based on feedback from global customers, enhancing performance and stability.
Rigorous quality validation ensures compliance with market demands and reliability.

HONPINE Anti-Backlash Planetary Gearbox: Redefining CNC Machine Tool Boundaries with Ultra-High Bending StiffnessAmong gearbox performance metrics, bending stiffness (often overlooked compared to precision and torsional stiffness) directly determines the limits of CNC machine tool machining. HONPINE’s anti-backlash planetary gearbox is redefining these limits with its ultra-high parameters.- Breaking Precision Barriers: How HONPINE's Anti-Backlash Planetary Reducer Outperforms Harmonic & RV ReducerThe ultra-high precision anti-backlash planetary reducer has an angle transmission accuracy of up to 7 arc seconds and a positioning accuracy of up to 5 arc seconds, which is much higher than the accuracy level of current harmonic reducers and RV reducers. Its torsional rigidity and main bearing overturning rigidity are much stronger than those of RV reducers, and the service life is longer than that of traditional harmonic reducers. Ultra-high precision anti-backlash planetary reducers give robots and machine tools better performance. They push the accuracy limit of ultra-high rigidity reducers to 15 arc seconds, filling the market gap and making ultra-high precision reducers available for high-end industrial machines.
- Robot Joint Module Parameter Power-Off Saving Operation GuideIn the daily use of robot joint modules, the stable preservation of parameters is the key factor to ensure the continuous and efficient operation of the equipment. For robot joint modules, mastering the correct parameter power-off saving method can effectively avoid data loss caused by accidental power failure.
RV Reducer Gearbox: The Core Technology Behind Industrial Robot PrecisionThe RV reducer gearbox is developed on the basis of traditional cycloid planetary transmission. Its reduction structure consists of the first-stage planetary reducer and the second-stage cycloid pinwheel reducer. It uses at least two eccentric shafts to connect the secondary reduction mechanism. The housing and cycloid pinwheel are matched and driven by solid castings and steel components, which form a closed differential gear train. The RV reducer gearbox not only overcomes the shortcomings of general cycloid pinwheel transmission but also has a series of advantages such as high precision (backlash less than 1 arc minute), high rigidity, high durability, high output density (high torque and compact), wide reduction ratio range, and low vibration.
24V 48V Robot Joint Module:Choose the Write Voltage for Robots and AutomationWhen selecting a robot joint module, voltage matching is a key factor that directly affects the performance, safety, compatibility, and operational stability of the equipment. Electrical components such as robots, servo motors, and controllers are designed to operate within a specific voltage range. In sufficient voltage can lead to insufficient power, slow response, or even failure to start; excessive voltage may burn out the circuit or shorten its life. HONPINE's standard joint modules include two voltages: 24V and 48V. They each play a unique role to ensure the efficient operation of robots and automation equipment.- Brushless Motor is an Important Component of Robot Joint ModuleAs manufacturing technology rapidly advances toward digitalization and intelligence, the robotics industry continues to evolve, introducing innovations that enhance automation in various fields.
