Patent ID: 8708858

Claim:
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 ).
