Description

Technical Field

[0001] The utility model belongs to the technical field of forming gear grinding and relates to a rotating arm structure for switching an outer grinding wheel to an inner grinding wheel. Background Art

[0002] Currently, existing grinding wheels for external gear shaping are typically around 400mm in diameter, while those for internal gear grinding are typically around 100mm in diameter. This difference in diameter makes it difficult for both to share the same shaping device. Furthermore, due to the different diameters of the internal and external grinding wheels, the required grinding speeds are also different, requiring the internal grinding wheel to rotate at a much higher speed than the external grinding wheel.

[0003] Therefore, a rotating arm structure for switching an outer grinding wheel to an inner grinding wheel is needed to solve the above technical problems. Utility Model Content
