Description

Technical Field

[0001] The utility model relates to the technical field of gear box devices, in particular to a spur gear planetary integrated gear box. Background Art

[0002] The planetary gear reducers that are common in the market and widely used in the machinery industry are mostly segmented.

During assembly, the cumulative errors of each section make it difficult to guarantee the overall accuracy, noise, and temperature rise of the reducer. In addition, it has particularly high requirements on the accuracy of processing equipment, workers' processing technology, and assembly technology, resulting in large processing volume, waste of working hours, and high production costs.
