Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The following is in conjunction with the appendix Figures 1-3 The present invention will be further described below.

[0020] In order to solve the problems existing in the background art, this application proposes the following technical solution: a dual-output gearbox.

[0021] The specific technical solution includes a housing 1, a first output mechanism 2, a second output mechanism 3, and a drive assembly 4 for providing power. The drive assembly 4 is located in the middle of the housing 1. The first output mechanism 2 and the second output mechanism 3 are located inside the housing 1 and are mirror images of each other on both sides of the drive assembly 4. The first output mechanism 2 includes a first output shaft 201 and a first linkage gear 202. One end of the first output shaft 201 is rotatably mounted on the inner wall of the housing 1, and the other end of the first output shaft 201 is located outside the housing 1. The first linkage gear 202 is mounted on the outer side of the first output shaft 201. The second output mechanism 3 includes a second output shaft 301 and a second linkage gear 302. One end of the second output shaft 301 is rotatably mounted on the inner wall of the housing 1, and the other end of the second output shaft 301 is located outside the housing 1. The second linkage gear 302 is mounted on the outer side of the second output shaft 301. The drive assembly 4 can simultaneously drive the first output mechanism 2 and the second output mechanism 3 to rotate, thus enabling dual output operation through the first output shaft 201 and the second output shaft 301.

[0022] In its specific implementation, the drive assembly 4 includes a motor 401, a rotating shaft 402, a driving gear 403, a driven rod 404, a driven gear 405, a driving bevel gear 406, a driven bevel gear 407, a transmission rod 408, and a central gear 409. The motor 401 is mounted on the outside of the housing 1. The rotating shaft 402 is located inside the housing 1 and mounted on the output end of the motor 401. One end of the driven rod 404 is rotatably mounted on the inner wall of the housing 1. The driven gear 405 is mounted on the driven rod 404 and meshes with the driving gear 403. The driving bevel gear 406 is mounted on the other end of the driven rod 404. The other end of the transmission rod 408 is rotatably mounted on the inner wall of the housing 1 and is perpendicular to the driven rod 404. The driven bevel gear 407 is mounted on the other end of the driven rod 404 and meshes with the driving bevel gear 406. The central gear 409 is installed on the outside of the transmission rod 408. The two sides of the central gear 409 mesh with the first linkage gear 202 and the second linkage gear 302 respectively. The motor 401 can drive the rotating shaft 402 to rotate. Therefore, the rotating shaft 402 can drive the driving gear 403 to rotate. The driving gear 403 can drive the driven gear 405 and the driven rod 404 to rotate. Then, the driven rod 404 can drive the driving bevel gear 406 to rotate. The driving bevel gear 406 can drive the driven bevel gear 407 and the transmission rod 408 to rotate. The transmission rod 408 can drive the central gear 409 to rotate. Since the central gear 409 rotates with the first linkage gear 202 and the second linkage gear 302, it can simultaneously drive the first output shaft 201 and the second output shaft 301 to rotate, thereby achieving the same output state of the two shafts and ensuring the coordinated and stable operation of the equipment.

[0023] In a specific implementation, a booster assembly 5 for improving the deceleration effect is provided inside the housing 1. The booster assembly 5 includes a hydraulic cylinder 501, a mounting plate 502, and two contact blocks 503. The hydraulic cylinder 501 is installed on the outside of the housing 1, and the mounting plate 502 is located inside the housing 1 and installed at the output end of the hydraulic cylinder 501. The contact blocks 503 are located on the mounting plate 502, and the two contact blocks 503 are located on the sides of the first output shaft 201 and the second output shaft 301, respectively. The booster assembly 5 can further enhance the deceleration degree as needed. During adjustment, the mounting plate 502 is pushed inward by the hydraulic cylinder 501, so that the contact blocks 503 can contact the first output shaft 201 and the second output shaft 301. Under the action of friction, the first output shaft 201 and the second output shaft 301 can be boosted.

[0024] Furthermore, the top of the contact block 503 is provided with a contact arc surface 6, which fits against the first output shaft 201 and the second output shaft 301, thus ensuring that the contact block 503 can be in tight contact with the first output shaft 201 and the second output shaft 301.

[0025] Furthermore, two grooves 7 are provided on the mounting plate 502. The bottom of the contact block 503 is engaged in the groove 7, and a limiting spring 8 is installed between the contact block 503 and the inner wall of the groove 7. The limiting spring 8 can limit the contact block 503. Therefore, when the contact block 503 contacts the first output shaft 201 and the second output shaft 301, the limiting spring 8 can increase the contact friction through its elastic force, thereby controlling the compression degree of the limiting spring 8 and controlling the magnitude of the contact friction, thereby adjusting the output torque of the first output shaft 201 and the second output shaft 301.
