Embodiment Construction
[0028] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0029] Such as Figure 1-2 As shown, a gearbox drive compressor motor bearing cooling and lubricating structure includes a shaft extension end bearing cooling structure and a non-shaft extension end bearing cooling structure. The cover 2, the shaft extension bearing 3 and the rotating shaft 4 form a closed oil chamber, which is sealed by a sealing assembly. The left end of the convex round end cover 1 is connected to the gear box 5, and the right end of the convex round end cover 1 is connected to the machine base 6 The oil chamber is connected to the gear box 5 through the oil outlet hole 101 and is connected with the compressor cooler through the oil inlet hole 102 to realize the cooling lubrication and circulation of the cooling oil 11 .
[0030] In order to facilitate the flow of cooling oil 11, the oil inlet hole 102 is connect...
