[0028] The specific operation is as follows: during the rotation of the main shaft 1, the rolling body inside the connecting bearing 2 will roll between the inner and outer rings to reduce friction. During the rolling process, the rolling body will continuously touch the first steel ball 503, driving the first steel ball 503 to roll inside the shell 501. At the same time, the top of the first steel ball 503 contacts the bottom of the second steel ball 505 through the ball groove 502, driving the second steel ball 505 to roll inside the shell 501. With the restriction of the second steel ball 505 by the spring 504, the second steel ball 505 can roll within a certain range.

The outer wall of the plate 702 is welded, and the top of the bottom support plate 7031 is fixedly connected with a tripod 7032, and the top of the bottom support plate 7031 is threadedly connected with a fastening bolt 7033, and the top of the reinforcement member 703 is fixedly connected with a fixing member 704, the fixing member 704 includes a fixing plate 7041, a guide slider 7042 and a bolt 7043, and the outer wall of the fixing plate 7041 is fixedly connected with the guide slider 7042, and one side of the fixing plate 7041 is penetrated and connected with the bolt 7043, one end of the base assembly 7 is connected with a motor 8, and the other end of the base assembly 7 is fixedly connected with an impeller 9, an outer side of the impeller 9 is provided with an organic hub 10, and the outer wall of the machine hub 10 is provided with an outlet flange 11, and the side of the machine hub 10 away from the main shaft 1 is connected with an organic cover 12;

[0030] The specific operation is as follows: when installing the transmission group structure, first connect the two ends of the main shaft 1 to the motor 8 and the impeller 9 respectively, then pull the extension plate 702 out from the inner side of the mounting frame 701 according to the distance between the transmission group structure and the fan housing, so that the guide slider 7042 slides along the inner wall of the guide slot 7013 until the bottom support plate 7031 hits the inner wall of the fan housing, and then fix the bottom support plate 7031 with the fastening bolt 7033 to complete the connection between the reinforcement member 703 and the fan housing, and then tighten the bolt 704.

[0031] In summary, according to Figure 1-Figure 6As shown in , the working principle of the fan transmission group structure with easy disassembly and assembly is as follows: First, when the transmission group structure is installed, the two ends of the main shaft 1 are respectively connected to the motor 8 and the impeller 9, and then according to the distance of the transmission group structure relative to the fan casing, the extension plate 702 is pulled out from the inner side of the mounting frame 701, so that the guide slider 7042 slides along the inner wall of the guide slide groove 7013 until the bottom support plate 7031 reaches the inner wall of the fan casing, and then the bottom support plate 7031 is fixed by the fastening bolt 7033 to complete the connection between the reinforcement member 703 and the fan casing, and then one end of the bolt 7043 is screwed into the threaded hole 7012 to fix the fixing member 704 with the mounting frame 701, and the main shaft 1 is completely installed. When the fan is in use, the main shaft 1 is driven to rotate by the motor 8, so that the rolling element inside the connecting bearing 2 rolls between the inner and outer rings, and continuously touches the first steel ball 503, driving the first steel ball 503 to roll on the inner side of the outer shell 501, and at the same time The top of the first steel ball 503 contacts the bottom of the second steel ball 505 through the ball groove 502, driving the second steel ball 505 to roll inside the shell 501, and the spring 504 restricts the second steel ball 505, so that the second steel ball 505 can roll within a certain range, and the lubricating oil in the oil storage tank 401 flows into the shell 501 through the oil outlet 403. Under the dual rolling of the first steel ball 503 and the second steel ball 505, the lubricating oil can be evenly applied to the rolling element connected to the bearing 2, and the lubricating oil gradually flows downward as the rolling element continues to roll, and finally flows into the bottom cover 603 along the oil outlet pipe 601 and the triple pipe 604 to complete the waste oil collection. At regular intervals, the transmission group structure should be disassembled for inspection and maintenance. First, the connection between the main shaft 1 and the motor 8 and the impeller 9 is released, and then the fastening bolt 7033 and the bolt 7043 can be reversed to release the connection between the reinforcement 703 and the fan housing, and the fixing part 704 and the mounting frame 701, and the main shaft 1 can be completely disassembled.
