Electric generator unit

An electric generator unit, comprising:

• a front flywheel (55), a back flywheel (27), a gear accelerating assembly, a planetary decelerating assembly, a middle shaft (16) and a tail shaft (42);
• the front flywheel (55) along with a shaft sleeve is mounted on the middle position of the tail shaft (42), the tail shaft (42) is coaxial with the middle shaft (16), a distal end of tail shaft (42) is coupled with a front end of the middle shaft (16) by the gear accelerating assembly, the gear accelerating assembly comprises a first planetary disc and a second planetary disc;
• a sun gear of the first planetary disc along with a shaft sleeve is mounted on the distal end of the tail shaft (42), and a sun gear of the second planetary disc along with a shaft sleeve is mounted on a front end of the middle shaft (16);
• each of the first and second planetary discs of the gear accelerating assembly further includes a planetary gear, and the two planetary gears corresponding to the first and second planetary discs are mutually coupled by a gear shaft;
• the back flywheel (27) and the planetary decelerating assembly along with a shaft sleeve is mounted on the middle shaft (16), the planetary decelerating assembly includes a third planetary disc and a turntable disc (9), a sun gear of the third planetary is concentric and mounted on middle shaft (16) along with a shaft sleeve, the turntable disc (9) has a single-row angular contact ball bearing corresponding to the position of planetary gear of the third planetary disc, the turntable disc (9) is mounted on a distal end of the middle shaft (16), the single-row angular contact ball bearing is coupled with the planetary gear of the third planetary disc by gear shaft (13).
