Abstract: Aiming at high failure rate resulting from poor working condition, heavy load and impact of heavy mining motorwheel dump trucks, an oscillator transmission reductor for motorwheel dump trucks with required design function of GE788 was presented. The structure and basic dimensions of oscillator transmission reductor were determined, and the stress and strength of meshing component in oscillator transmission reductor were estimated and calculated. The results indicate that the proposed oscillator transmission reductor satisfies the design requirement and provides a reference for the design of wheel reductors of motorwheel dump trucks.
Key words: motorwheel dump truck; wheel hub reducer; oscillatory roller transmission
