Objective: to improve the operational performance of gearbox housings in locomotives and prevent lubricant losses during rolling stock operation. Methods: an analysis of locomotive gearbox housing damage was conducted to identify underlying causes. Existing gear housing designs were reviewed with emphasis on reliability, strength, and structural stiffness. Results: design solutions for the gear housing have been proposed to enhance its strength, stiffness, and durability, while reducing lubricant consumption. Practical significance: the proposed improvements will enable increased locomotive mileage without additional outfitting of wheel–motor units. The environmental imperative for adopting the enhanced gearbox housing design has been emphasized.
