Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to an oil guide groove. Background Art

[0002] With the advancement of science and technology and the development of industry, the application of oil guide groove technology is becoming more and more extensive in various fields. In the field of compressors, with the continuous development of refrigeration technology, the demand for refrigeration oil flow guidance is also increasing, which has promoted the innovation and development of oil guide groove technology.

[0003] At present, in the prior art, a Chinese patent with a publication number of CN216198715U discloses a main shaft bearing waste oil guide groove, which surrounds the lower part of the bearing body through the oil guide groove body, and can completely collect the grease discharged from the main bearing, so as to prevent the grease from falling onto the yaw platform and the tower platform, causing inconvenience in related work and hidden dangers of the fan. However, in actual use, the device may cause grease overflow due to the design or inclusion range limitation of the oil guide groove. It can be considered to optimize the shape and size of the oil guide groove to make it better adapt to the shape of the bearing body, reduce the obstruction of the grease in the flow process, and improve the collection efficiency. It can also be considered to design the oil guide groove to be detachable, so that it can be easily removed from the equipment when it needs to be cleaned or replaced. In view of this, we propose an oil guide groove. Utility Model Content
