Two-stage speed reduction power double-branch bevel gear transmission mechanism

The invention discloses a two-stage speed reduction power double-branch bevel gear transmission mechanism, and relates to a transmission mechanism. The invention aims to solve the problems that a gear box is large in size, high in weight and complex in structure due to an existing single-branch transmission mode, the arrangement of the gear box is limited, and the application has certain limitation. The transmission comprises a first-stage small bevel gear I, an input small bevel gear II, a first-stage large bevel gear I, an elastic shaft I, a second-stage cylindrical small gear I, a second-stage cylindrical large gear, a second-stage cylindrical small gear II, an elastic shaft II, a first-stage large bevel gear II, an input shaft system and an output shaft, and the first-stage large bevel gear I and the second-stage cylindrical small gear I are fixedly connected to the elastic shaft I; the elastic shaft I is fixedly connected with an input small bevel gear I, the elastic shaft II is fixedly connected with a
