Description

Technical Field

[0001] This utility model relates to the field of multi-diameter adapter technology, specifically to a multi-diameter adapter for a gearbox breather. Background Technology

[0002] As a consumable spare part on the gearbox, the gearbox breather needs to be replaced regularly. The gearboxes at the Danjinghe Wind Farm are manufactured by two companies: Nanjing High Speed ​​Gearbox Co., Ltd. (Nanjing Gearbox) and Chongqing Gearbox Co., Ltd. (Chongqing Gearbox). However, even within the same manufacturer, the diameter of the breather mounting holes on the gearbox housings differs. This necessitates purchasing multiple models and from multiple manufacturers in advance for regular breather replacements, causing inconvenience in the procurement process. Furthermore, it is crucial to confirm the specific model of the breather for the unit beforehand; bringing the wrong spare part requires a second return to the factory, extending the unit's downtime and impacting power generation. Utility Model Content

[0003] Technical problems to be solved

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a multi-diameter adapter for a gearbox breather, which can effectively solve the problems in the existing technology.

[0005] Technical solution

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a multi-diameter adapter for a gearbox breather, including a breather. The bottom end of the breather is fixedly connected to a breathing tube, one end of the breathing tube is fixedly connected to the top end of an adapter frame, and the bottom end of the adapter frame is connected to two sets of sleeve tubes. One end of one sleeve tube is connected to the top end of the gearbox, and the other sleeve tube is fixedly connected to a connecting cap. A nut is fixed to the outside of the connecting cap.

[0008] Furthermore, the adapter frame is a three-way pipe structure, and the top of the adapter frame is provided with three sets of sleeve pipes, and the inner diameters of the three sets of sleeve pipes are all different.

[0009] Furthermore, the top sleeve is engaged and fixed with the breathing tube, one side of the bottom sleeve is engaged with the top of the gearbox, and the other side of the bottom sleeve is engaged and fixed with the connecting cap.

[0010] Furthermore, nuts are fixed to the outside of both the connecting cap and the top sleeve tube.

[0011] Furthermore, the outer wall of the breathing tube, the inner wall of the sleeve tube, the inner wall of the connecting cap, and the inner wall of the gearbox are provided with threaded structures.

[0012] Furthermore, the adapter frame is a trapezoidal hollow structure.

[0013] Beneficial effects

[0014] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0015] This utility model, through its adapter frame structure, allows users to install a sleeve structure with a specific diameter as needed. The upper part connects to the breathing tube in the breather, and the lower part connects to the gearbox. Excess sleeve at the bottom is sealed with a connecting cap. Therefore, it features three sets of adapter pipe structures of different sizes, which can be combined with connectors of different diameters. The top of the adapter pipe connects to the breathing tube, and the two bottom sleeves connect to two gearbox diameters. This allows for the purchase of only one reliable breather while ensuring compatibility with other gearbox models, thus standardizing wind farm management. Using the same breather spare part for multiple wind turbines accelerates maintenance efficiency, reduces wasted effort in procurement and spare parts selection, improves work efficiency, and ensures unit power generation.

[0016] By designing an adapter that can be directly installed on the pre-drilled hole of the respirator, the outlet diameter of the respirator can be standardized, and the spare parts model of the respirator can be standardized, saving time and effort. The application of this design will unify the planning of the model of gearbox respirators, increase power generation and greatly improve work efficiency. Attached Figure Description
