Low-profile, rotating-shaft transmission device, and associated method

A method of manufacturing a low-profile, rotating-shaft transmission device, comprising:

• mounting an output gear in an offset gearbox assembly, configured to couple rotatable input and output shafts, such that the output gear is rotatable in a drive direction about an output gear axis to rotate the output shaft coupled thereto, the output shaft extending in an output axial direction and the input shaft extending in an input axial direction;
• mounting an idler gear in the offset gearbox assembly, such that the idler gear is coupled to the output gear and is rotatable about an idler gear axis in association with the output gear;
• and
• mounting an input gear assembly in the offset gearbox assembly, such that the input gear assembly is coupled to the idler gear and is rotatable about an input gear axis in association with the idler gear, with the input gear assembly being coupled to the input shaft such that rotation of the input shaft causes rotation of the output gear in the drive direction via the input gear assembly and the idler gear, and with the input gear assembly having the input shaft coupled therewith such that the input axial direction of the input shaft is nonparallel to the output axial direction of the output shaft.
