The reliable and cost-effective solution for grinding of gear shafts in the wind power industry

The wind power industry, as a key player in the global transition to renewable energy, relies on high precision components to ensure the optimal performance and longevity of wind turbines. One of the critical components of wind turbines are the gear shafts, which are responsible for transmitting power from the turbine blades to the generator. These gear shafts undergo a rigorous manufacturing process to meet the specific demands of the wind industry, with gear shafts grinding being one of the most essential steps in ensuring their reliability and efficiency.

How does the JUNKER KARGO overcome key challenges in grinding gear shafts for wind turbines?

High load requirements: With a grinding length capacity of up to 5.000 mm, the KARGO series can grind wind turbine gear shafts with unbeatable precision and availability.
Durability and longevity: Wind turbines often operate in remote and harsh environments, where maintenance can be difficult and costly. The JUNKER KARGO series provides the best grinding quality due to the automatic compensation of disturbance variables.
Tight tolerances and geometric precision: The performance of gear systems relies on the precision of the part. The KARGO series is equipped with an absolute measuring system which swivels in when needed, allowing to measure the workpiece pre process, in process, and post process.
Surface finish and noise reduction: A smooth surface finish is essential to reduce friction as wind turbines must operate as quietly as possible to minimize noise pollution. The JUNKER KARGO series can be equipped with corundum, CBN, or diamond grinding wheels. KARGO can achieve maximum flexibility and high quality surface finish.

Grinding processes on the KARGO series for gear shafts

To meet the demanding requirements of the wind industry, several grinding techniques are used in the manufacturing of gear shafts:

External cylindrical grinding: KARGO achieves high precision grinding of gear shafts while ensuring that the gear shafts align perfectly with other components by using straight and angular plunge-cut grinding technologies.
Internal cylindrical grinding: Internal cylindrical grinding enables the precise grinding of internal functional surfaces such as bores, cones, or flat surfaces.
Grooves and thread grinding: For shafts that require threaded profiles, KARGO can grind grooves and threads with custom profiled grinding wheels.
