AI Technical Summary
Existing omni-directional wheels require additional installation space and suffer from inefficiencies in force transmission due to the need for intermediate transmission units, and they often have limited contact surface area with goods to be conveyed.
The omni-directional wheel design features rollers that are directly driven by a drive worm, eliminating the need for additional installation space and utilizing a combination of worm drive and helical teeth for efficient force transmission, with rollers having a high contact surface area and optimized material properties for better grip on goods.
The design results in compact, efficient wheels with minimal loss in force transmission and enhanced contact surface area, allowing for effective conveyance of goods.
