· Core Materials:
· Polymer wheels: High-strength nylon (PA66) or polyurethane (PU) with Shore hardness 85A–95A for low-noise operation and vibration damping
· Steel variants: Carbon steel (ASTM 1045) or stainless steel with galvanized coatings (≥80 μm) for heavy-load applications (e.g., AGVs in industrial logistics)
· Surface Treatments:
· PTFE coatings reduce friction coefficients to 0.04–0.06, enhancing omnidirectional maneuverability
· Rubber tires bonded to wheel rims for noise reduction and shock absorption in sensitive environments (e.g., medical facilities)
· Roller Configuration:
· Free-spinning rollers mounted at ±45° angles on a central hub to enable omnidirectional motion
· Bendable anisotropic friction nodes for adaptive grip on uneven surfaces in robotic platforms
· Bearing Systems:
· Double-sealed ball bearings (e.g., 608ZZ series) with ISO-certified grease for smooth multidirectional rotation
· Thrust bearings integrated into vertical stems to minimize rotational resistance during alignment shifts
· Modularity: Split-frame designs with adjustable roller spacing (50–200 mm) for rapid maintenance and load customization
00001. Injection Molding: Precision molds for PU/nylon wheels with tolerance ±0.1 mm and Ra ≤0.8 μm surface finish
00002. Assembly:
· Laser-aligned press-fit bearings to ensure concentricity (≤0.05 mm deviation)
· Automated adhesive bonding of rubber tires for uniform thickness (±0.2 mm)
00003. Testing: Load cycling (50–500 kg) and thermal shock (-30°C to +120°C) validation for industrial compliance
