Claim:
1. A reduction gear system comprising: an orthogonal shaft reduction gear assembly; a parallel shaft reduction gear assembly; and a joint plate disposed between the orthogonal shaft reduction gear assembly and the parallel shaft reduction gear assembly, along an axial direction of an output shaft of the orthogonal shaft reduction gear assembly, wherein the orthogonal shaft reduction gear assembly includes an orthogonal shaft reduction gear casing, a first input shaft, a bevel pinion disposed on the first input shaft, a bevel gear configured to engage with the bevel pinion, and the output shaft on which the bevel gear is disposed, the parallel shaft reduction gear assembly includes a parallel shaft reduction gear casing, a second input shaft to which a rotation of the output shaft is transmitted, and a parallel shaft gear which is driven by the second input shaft, the orthogonal shaft reduction gear casing and the parallel shaft reduction gear casing are connected through the joint plate, the orthogonal shaft reduction gear casing has a flange portion protruding to the outside of the orthogonal shaft reduction gear casing, and the orthogonal shaft reduction gear casing and the joint plate are connected by a first bolt inserted into the flange portion from the orthogonal shaft reduction gear assembly side, and a second bolt inserted into the joint plate from the parallel shaft reduction gear assembly side.
