Mechanical Dimension
Wide Speed Ratio with a Long Service Lifespan
For the same amount of load capacity, a planetary gearbox has a higher service lifespan than the traditional gearboxes. Therefore, these gearboxes are easy to handle and install. These are key aspects that can improve efficiency and reliability in any mechanical system.
Again, the arrangement of gears is such that the entire system remains stable and reliable.
