Product Description
Harmonic reducer is a new type of reduction device, mainly composed of three basic components: wave generator, flexible gear (flexwheel), and rigid gear (rigid wheel). Harmonic reducer is widely used in industrial robots, CNC machine tools, aerospace, medical equipment, automated production lines and other fields. In the field of robotics, it can achieve high-precision position control to ensure that the robot's end effector can accurately reach the predetermined position and perform delicate operations, such as assembling tiny parts and welding electronic products. Although it is small in size, it can provide a large torque in a limited space to meet the power requirements of the robot in situations such as carrying heavy objects and performing complex processing tasks.

Technological Features
1. Special process of flexible wheel
We have innovatively invented the method of finishing after deformation in the flexible wheel tooth processing process, which solves the problem of uneven contact of traditional steel flexible wheels while ensuring accuracy, making the tooth surface fully engaged, more evenly stressed, less frictional, and more durable.
2. Innovative invention of S-tooth design
We have jointly conducted research on how to smoothly transmit friction and reduce the friction coefficient of tooth cutting with the Deep Sea Silent Transmission Laboratory of colleges and universities, and innovatively invented the S-shaped harmonic tooth profile design theory, and combined kinematics, friction mechanics and lubrication to design simulation software that automatically generates s-shaped curves.
3. Independent design and development of tools
We have creatively developed an integrated composite tool with front cutting and back pressing in the processing of Zhubo gears, which has solved the market gap caused by the difficulty of tool manufacturing for micro harmonic reducers, and developed a series of micro harmonic reducer products unique to the industry.
Product Display
The harmonic reducer is small in size and light in weight, and can be installed in the small space of the robot hand to provide precise power transmission and motion control for the hand joints, allowing the robot hand to achieve flexible movements. In addition, the low vibration and low noise characteristics of the harmonic reducer also help reduce vibration and noise during hand joint movements, improving the operational stability and quietness of the robot. The limbs of humanoid robots need to complete various complex and delicate movements, such as grabbing objects, walking, climbing, etc. The harmonic reducer has high transmission accuracy, which can ensure that the robot's limb joints accurately reach the predetermined position and achieve high-precision motion control.
With the rapid development of science and technology, harmonic drive technology is also constantly evolving. The research and development and application of new materials have brought more excellent mechanical properties and durability to components such as flexible wheels, enabling them to operate stably under more stringent working conditions. At the same time, the introduction of advanced manufacturing processes such as precision CNC machining and special molding technology has made a qualitative leap in the manufacturing accuracy and production efficiency of harmonic drive devices, further reducing production costs and improving the market competitiveness of products.
