It is often used as a reduction transmission device between the prime mover and the working machine. It matches the speed and transmits torque between the prime mover and the working machine or actuator. It is widely used in modern machinery.

However, installing a high-power motor requires the power grid to have a large load, especially at startup, the high-power motor will impact the power grid. Sometimes, if the load is not enough, it is necessary to increase funds to add transformers to improve the line, which increases the cost of use, makes the transformation difficult, and reduces the economic benefits.

DETAILED DESCRIPTION

[0016] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0017] Example 1

[0018] See also Figure 1 to Figure 2The embodiment of the utility model discloses a double-lever driven gear booster system, which is mainly composed of a lever driving device, a gearbox and connecting parts. The gearbox includes a box body 1. The box body 1 adopts a rigid shell structure and adopts a structure in which the upper and lower parts are connected, which is convenient for disassembly and maintenance, and increases the structural strength to ensure the stable operation of the internal transmission parts. An input shaft 3 is arranged at the lower part of the box body 1. The input shaft 3 is installed at the lower part to ensure stability. Both ends of the input shaft 3 protrude from the outside of the box body 1, which is convenient for connection with the lever driving device. Both ends of the input shaft 3 are subjected to force to maintain balance and improve stability.

[0019] A first gear 101 is installed at the middle position of the input shaft 3. The first gear 101 meshes with the second gear 102 and the third gear 103 on the two shafts respectively to form two independent transmission paths. The second gear 102 is installed on the intermediate shaft, and the third gear 103 is installed on the output shaft 2. It is worth noting that the second gear 102 and the third gear 103 are both provided with check bearings with opposite installation directions. The intermediate shaft and the output shaft 2 are connected to each other through the fourth gear 104 and the fifth gear 105 on each of them. When the input shaft 3 rotates forward, the first gear 101 drives the third gear 103 on the output shaft 2 to rotate to form power output. Since the check bearing of the second gear 102 is installed in the opposite direction to the check bearing of the third gear 103, the second bearing will not drive the intermediate shaft to rotate. The fifth gear 105 drives the fourth gear 104 and the fifth gear 105 to rotate. The rotation of gear 104 does not interfere with the second gear 102. When the first gear 101 rotates in the opposite direction, the intermediate shaft and the fourth gear 104 are driven to rotate through the second gear 102. The fourth gear 104 is meshed with the fifth gear 105, and then drives the output shaft 2 to form power output. Since the rotation direction of the fifth gear 105 is the same as the rotation direction when the third gear 103 is driven, the rotation direction of the output shaft 2 is the same regardless of whether the first gear 101 rotates forward or reverse, preventing unexpected rotation of the gear under the action of reverse force, and improving the stability and safety of the system. Both ends of the output shaft 2 also protrude from the box 1, which is convenient for connection with subsequent working machines or actuators, and two groups of fourth gears 104 and fifth gears 105 are provided, which can maintain a balanced force structure during use and maintain a stable use state.

[0020] The lever driving device includes a frame for supporting the gearbox housing 1, the frame is arranged on both sides of the housing 1, and a connecting rod 503 is hingedly arranged on the top of the frame. One end of the connecting rod 503 is installed with a sector tooth 504, which meshes with the input gears 301 at both ends of the gearbox input shaft 3. The other end of the connecting rod 503 is connected to the driving device to form a bridge for power transmission. The connecting rod 503 is connected to the input gear 301 through the sector tooth 504. The connecting rod 503 is hinged to the frame through a rotating shaft, and the rotating shaft is arranged at one end close to the sector tooth 504, and the connecting rod 503 The end length is much larger than the length from the rotating shaft to the input gear 301, so that the connecting rod 503 can swing within a certain range, and then the connecting rod 503 forms a lever effect during the swinging process, making it easier to drive the input shaft 3 to rotate, and the connecting rod 503 drives the input shaft 3 to rotate forward and reverse through the fan-shaped teeth 504 when swinging, and then cooperates with the second gear 102 and the third gear 103 to ensure that the rotation direction of the output shaft 2 is consistent, thereby adapting to the power transmission requirements under different working conditions. The connecting rod 503 is provided with two to ensure the stability of the input and improve the use effect.

[0021] The driving device includes a driving motor 4, and the output end is connected to the rocker arm 5 through a reducer 401. The function of the reducer 401 is to reduce the output speed of the motor and increase the output torque to achieve the use needs of high torque and low speed. Rockers 5 are installed at both ends of the reducer 401. The length of the rocker arm 5 is set according to needs. A counterweight block 501 is provided at one end of the rocker arm 5 to balance the inertial force of the rocker arm 5 during the swinging process to reduce vibration and noise. The other end of the rocker arm 5 is hinged to the connecting rod 503 through a connecting rod 502, so that the connecting rod 503 forms a swinging effect, thereby driving the gearbox to rotate and realizing effective power transmission. The two rocker arms 5 work synchronously to improve the stability and reliability of the system, and jointly drive the connecting rod 503 and the gearbox to achieve double power protection.

[0022] When the driving motor 4 is started during use, its power is transmitted to the rocker arm 5 through the reducer 401. The rocker arm 5 maintains balance under the action of the counterweight 501, and pushes the connecting rod 503 to swing through the connecting rod 502. The fan-shaped teeth 504 on the connecting rod 503 mesh with the input gear 301 of the gearbox input shaft 3, and transmit the power to the inside of the gearbox. Inside the gearbox, the gears are matched to ensure that the power is increased and transmitted when the input shaft 3 rotates forward and reverse periodically. Finally, the power is output to the working machine or the actuator through the output shaft 2, completing the entire power transmission process. Through the lever principle and gear transmission design, the effective transmission and increase of power are realized, which has the advantages of simple structure, high transmission efficiency, good stability, etc., and is particularly suitable for working conditions requiring large loads and low speeds.

[0023] Example 2

[0024] The main difference between this embodiment and embodiment 1 is that a hydraulic cylinder 6 is used to drive the connecting rod 503. The hydraulic cylinder 6 is hinged at the end of the connecting rod 503. The hydraulic cylinder 6 is driven to extend and retract by a pump station, so that the connecting rod 503 swings, prompting the sector teeth 504 to drive the input gear 301 to rotate, thereby achieving stable power input in the case of high-torque drive and improving the driving effect.
