Abstract
A transmission device for a cutter disk drive shaft of a farmland ditcher comprises a drive shaft assembly used for providing power, a speed reducer used for adjusting and outputting power and a bearing seat assembly used for installation of the drive shaft assembly on a shell of the speed reducer. One end of a bearing supporting sleeve is connected with a spiral bevel gear in the speed reducer. The other end of the bearing supporting sleeve is provided with a clamp nut used for adjusting the pre-tightness of a tapered roller bearing. The output end of the drive shaft in the drive shaft assembly penetrates through the bearing supporting sleeve from the end provided with the clamp nut and is connected with the spiral bevel gear fixed to the other end of the bearing supporting sleeve. According to the transmission device, since the spiral bevel gear and the cutter disk drive shaft are connected indirectly through the bearing supporting sleeve, connection is realized appropriately, it can be guaranteed that the cutter disk drive shaft transmits all torque, and meanwhile adjustment of a back lash and a meshing print of a bevel gear pair can be conducted quite conveniently when necessary.
