[0002] In mechanical transmission systems, power amplification and output speed adjustment are common requirements. Conventional power amplification devices often have complex structures, low efficiency, and precise speed adjustment is difficult.

[0005] To achieve the aforementioned purpose, the present utility model provides the following technical solutions: A power amplification device, characterized in that it comprises: The device body comprises a base, a left machine plate, and a right machine plate, each attached to the left and right sides of the base, respectively. Between the upper parts of the left machine plate and A fixed shaft is provided on the right machine plate, and an opening is provided through the central position of the lower parts of the left machine plate and the right machine plate.

[0006] The starting gear consists of two starting gears that rotate on the left and right sides of the base, and a starting gear in the center. The three starting gears mesh parallel to each other, and the starting gears on the left and right outer sides are coaxially equipped with reciprocating semicircular gears.

[0007] The output shaft and flywheel are located between the upper front of the left machine plate and the right machine plate. The output shaft runs through the bearing on the left machine plate and is connected to the flywheel.

[0008] The fixed shaft and the gravity pendulum system. The fixed shaft is located between the left and right engine plates, behind the flywheel assembly, and is higher than the flywheel assembly. The gravity pendulum rotates on the fixed shaft. The lower part of the gravity pendulum is located at the top of the center starter gear and engages with the forward and other semicircular gears of the two left and right outboard motors, and the upper part of the gravity pendulum is connected to the rotating shaft by a connecting rod. The described rotating shaft is rotatably mounted on the right engine plate by a bearing and is connected to the flywheel by a connecting rod.

[0009] Furthermore, the tooth shape of the reciprocating semicircular gear is designed as a semicircle to achieve periodic engagement and disengagement with the lower part of the gravity pendulum, thereby driving gravity up and down.

[0010] Furthermore, it also includes a drive mechanism comprising a motor and an output gear, with an L-shaped mounting motor on the outside of the left or right machine plate. The motor drives the output gear, which in turn drives one of the starting gears on the left or right outside, causing it to rotate.

[0011] When the drive mechanism sets the starting gear in motion, the meshing action of the reciprocating semicircular gear and the gravity pendulum, along with the transmission linkage between the gravity pendulum and the flywheel via the connecting rod, amplifies the input power and adjusts the output speed. Specifically, the lever ratio is 5:1 and the output ratio is 2:1; that is, if the input speed is 100 rpm, the output speed is 50 rpm.

A fixed shaft 13 is provided between the upper parts of the left machine plate 11 and the right machine plate 12, and an opening is provided through the central position of the lower parts of the left machine plate 11 and the right machine plate 12 for installing and securing other components.

[0014] The starting gear: It consists of two starting gears 20, which are rotated on the left and right sides of the base 10, and a starting gear in the middle 21. The three starting gears mesh parallel to each other, and the starting gears 20 on the left and right outer sides are coaxially provided with reciprocating semicircular gears 30 to achieve periodic engagement and disengagement with the lower part of the gravity pendulum 40.

[0015] The output shaft and flywheel: The output shaft 50 and the flywheel are arranged between the upper front of the left machine plate 11 and the right machine plate 12. The output shaft 50 passes through the bearing located on the left machine plate 11 and is connected to the flywheel 60.

[0016] The fixed shaft and the gravity pendulum system: The fixed shaft 70 is located between the left machine plate 11 and the right machine plate 12 and is situated behind the flywheel assembly, extending higher than the flywheel assembly.

The described rotating shaft 90 is rotatably mounted on the right machine plate 12 by means of a bearing and is connected to the flywheel 60 by a connecting rod.

[0017] The specific embodiment: Design of the reciprocating semicircular gear: The tooth shape of the reciprocating semicircular gear is semicircular to achieve periodic engagement and disengagement with the lower part of the gravity pendulum, thereby causing the pendulum to swing up and down. This design enables the gravity pendulum to perform a periodic up-and-down motion, driven by the reciprocating semicircular gear, and then transmits the force via the connecting rod and rotating shaft to the flywheel.

[0019] Power amplification and speed adjustment: When the drive mechanism sets the starting gear in motion, input power amplification and output speed adjustment are achieved through the engagement of the reciprocating semicircular gear and the gravity pendulum, as well as the transmission link between the gravity pendulum and the flywheel via the connecting rod. Specifically, the utility model features a lever ratio of 5:1 and an output ratio of 2:1, meaning that if the input speed is 100 rpm, the output speed is 50 rpm. This design allows the utility model to precisely adjust the output speed while simultaneously ensuring power amplification.
