Description

Technical Field

[0001] The utility model relates to the technical field of compressor equipment, in particular to a compressor speed-increasing gear structure. Background Art

[0002] In the compressor field, the speed-increasing gear structure is a key component for achieving efficient power transmission. However, existing speed-increasing gear structures often face the problem of insufficient stability during high-speed operation. Due to assembly precision issues, traditional gear structures are prone to slight vibration in the structure, reducing the rigidity of the entire system, especially under high-speed operation and load fluctuations. To address this problem, we propose a compressor speed-increasing gear structure. Utility Model Content

[0013] (3) Beneficial effects

[0014] The embodiment of the present invention provides a compressor speed-increasing gear structure, which has the following beneficial effects:

[0015] 1. When the internal gear meshes with the inner ring gear, the shaft secures it to the gear carrier, ensuring stable operation of the internal gear and the inner gear. By concentrically arranging the internal gear and the inner gear, the inner wall of the inner gear closely aligns with the inner wall of the inner ring gear, increasing the rigidity of the system and reducing relative motion and vibration between the gears, thereby improving operational stability.
