How did gearbox works?
Could you elaborate on the intricate workings of a gearbox? How does it manage to translate engine power into rotational motion at varying speeds and torque levels? What are the specific components and their interactions that enable this transformation, and what are the potential challenges that need to be addressed for optimal performance? I'm particularly curious about the gear ratios, the role of lubrication, and the overall design considerations that contribute to the efficiency and durability of a gearbox.
