Abstract

The utility model belongs to the technical field of power generation equipment, and particularly relates to a speed increasing mechanism which comprises a box body, a speed increasing module is arranged in the box body, the speed increasing module comprises a shell, and a rotating disc and a rotating shaft are arranged in the shell. The rotating disc comprises a central column and a disc, the rotating shaft comprises a shaft rod and a gear, the shaft rod is perpendicular to the central column, the gear is coaxially fixed to the shaft rod, and the gear is meshed with insections on the disc; the rotating disc rotates to drive the shaft rod to rotate synchronously. A plurality of speed increasing modules are provided; and in every two adjacent speed increasing modules, the shaft rod of one speed increasing module is in transmission connection with the central column of the other speed increasing module. According to the utility model, energy obtained by a plurality of speed increasing modules can be concentrated on the shaft rod of one speed increasing module to be output uniformly, and meanwhile, multi-stage speed increasing can be realized.
