Abstract

This paper systematically reviews the research status of RV reducers as key components in robotics, covering technical directions such as fault diagnosis, vibration analysis, and load-bearing performance optimization. A comprehensive technology matrix is constructed, and strategic development pathways for the industry are proposed. Benefiting from advantages including high precision, large torque capacity, and compact size, RV reducers are widely applied in fields such as robotics, CNC machine tools, and aerospace. The global market size grew from RMB 3.43 billion in 2018 to RMB 7.51 billion in 2023, with a Compound Annual Growth Rate (CAGR) of 16.97%. While domestic market share has exceeded 60%, the localization rate in high-end segments remains below 30%, constrained by bottlenecks such as reliance on imported critical processing equipment and incomplete design theory systems.
