Global Wave - Humanoid Robots

Currently, the global humanoid robot industry is still in its early stages of development. During the process of research and development, many companies have realized that the focus of robot development is on continually improving its perception, decision-making, and execution capabilities. As a result, key components have become hot spots for market investment and testing.
Among the key components of humanoid robots, the drive system accounts for 50% of the overall value of the robot. Components such as the gearbox, sensors, and motors play a decisive role in enabling the robot to execute actions smoothly and precisely. The harmonic reducer bearing mentioned in this article is a key component for achieving high-precision motion control. It is also an extremely important part of the reducer, as it not only affects the robot's motion performance and precision but also directly relates to the robot's energy efficiency, durability, and reliability.
The Role of Harmonic Reducer Bearings:
Support: Provide support for the harmonic reducer, ensuring stable operation during use.
Torque Transmission: Transmit power through the bearings, ensuring that the movement is executed accurately and smoothly.
Friction Reduction: High-precision harmonic reducer bearings reduce internal friction during operation, improving efficiency and extending service life.

Common Types of Harmonic Reducer Bearings:
1. Crossed Roller Bearings
Characteristics: Crossed roller bearings offer high rigidity and load-bearing capacity. They can withstand radial, axial, and overturning moments, making them suitable for space-constrained scenarios.
Advantages:High precision, high rigidity, low friction, high speed, and high reliability.
Simple and compact structure, high rotational precision, and easy maintenance.
Applications: Ideal for applications requiring high-precision control in humanoid robot joints and other industrial robots.
