Product Details
A flexure bearing is a specialized type of bearing that transmits motion and power through controlled elastic deformation. Its defining feature is a thin-walled outer ring that undergoes cyclic deformation under load. This design makes it a critical component in harmonic drive reducers: as the wave generator rotates, the outer ring of the flexure bearing deforms into an elliptical shape in tandem with the flexspline, and the contact between the rolling elements and the raceways converts high-speed rotation into low-speed, high-torque output, achieving precision reduction ratios ranging from 1:30 to 1:320.
Its technical advantages lie in its multi-dimensional adaptability: the thin-wall structure reduces weight by 30%–50% and volume by 40%, meeting the stringent lightweight requirements of aerospace applications and humanoid robotics; its elastic deformation capability can compensate for shaft misalignment of ±0.1 mm, thereby lowering installation accuracy requirements; by distributing the load, it achieves high radial and axial load-carrying capacity while reducing frictional resistance by 20%–30% compared with conventional bearings and lowering operating noise by 10–20 dB. In terms of materials, it predominantly employs a composite structure of GCr15 high-carbon chromium bearing steel and polytetrafluoroethylene, balancing high yield strength with the need for elastic deformation.
The application scenarios span the high-end manufacturing sector: supporting motion control in industrial robot joints with repeat positioning accuracy of ≤0.02 mm; providing reliable transmission for harmonic drive units in the Shenzhou spacecraft series; and enabling anthropomorphic motion output in core joints such as the shoulders and hips of humanoid robots. The design and manufacturing of these components require overcoming challenging process hurdles, including 360° ball-filling assembly and achieving a fatigue life of 10⁷ cycles under cyclic stress loading. Currently, domestic enterprises such as Hebei Precision have already broken through key technologies, establishing a comprehensive theoretical framework and mature production lines.
