Abstract:
A generating apparatus comprising:an AC generator having a stator arranged around a rotary shaft and a rotor secured to the rotary shaft and provided with an annular portion surrounding an outer peripheral portion of the stator;a manual rotary driver mechanism including an accelerator engaging with a gear mounted on the rotary shaft of the generator; anda rotary driver engaging with the accelerator and operative to drive the rotor of the AC generator to rotate through the accelerator and the gear mounted on the rotary shaft of the AC generator so as to cause the AC generator to generate electric power when the rotary driver is rotated, whereinthe diameter of the gear mounted on the rotary shaft of the AC generator is selected to be substantially larger than a diameter of the rotary shaft, thereby decreasing a force required to rotate the gear mounted on the rotary shaft,the diameter of the gear mounted on the rotary shaft of the AC generator is selected to be substantially the same as a diameter of the stator and only slightly smaller than an outer diameter of the annular portion of the rotor, thereby accelerating a peripheral speed of the annular portion of the rotor more than a peripheral speed of the gear mounted on the rotary shaft of the AC generator, and whereinthe accelerator includes a plurality of gears mounted on a plurality of rotary gear shafts, wherein the plurality of rotary gear shafts are aligned so as not to be mutually perpendicular and not to be perpendicular to the rotary shaft of the generator, so that the plurality of rotary shafts are mutually aligned in parallel and are parallel to the rotary shaft of the generator, thereby to reduce an overall size of the generating apparatus.
