Description

Technical Field

[0001] This utility model relates to a walking wheel, specifically a compact drive wheel. Background Technology

[0002] Traditional drive wheel designs face numerous challenges in existing wheeled mobile equipment, especially those operating in clean or space-constrained environments. Traditional drive wheel systems often employ open or semi-enclosed structures, which are prone to accumulating dust and debris over long-term use. This not only increases maintenance costs but can also adversely affect the normal operation of the equipment. Furthermore, grease leakage is a significant problem in traditional designs, contaminating the working environment and potentially damaging the equipment itself and surrounding devices.
