The planetary gearbox is used in the drivetrain of construction machinery such as excavators, cranes, and loaders. It is usually installed between the engine and the hydraulic pump, providing the necessary torque for the machinery to work.
The planetary gearbox is used in wind turbines to convert the low-speed rotation of the blades into high-speed rotation that is necessary to generate electricity. It is usually located between the blades and the generator.
The planetary gearbox is used in industrial automation equipment such as robots, CNC machines, and conveyor systems. It is usually installed in the drivetrain, providing the necessary torque and speed reduction.
When replacing an old planetary gearbox, the following parameters should be considered to find a suitable replacement:
It is important to note that each parameter affects the performance of the gearbox and must be carefully considered before making a replacement. See the image below:
