Description

Technical Field

[0001] This utility model belongs to the field of speed reducer technology, and in particular relates to a dual-power gear transmission flat-head speed reducer. Background Technology

[0002] A speed reducer is a power transmission mechanism with extremely wide applications in the mechanical field. From high-power transmission to low-load, precise angle transmission, it can be found everywhere. Between the prime mover and the working machine or actuator, the speed reducer plays a crucial role in matching speeds and transmitting torque. It can reduce the rotational speed of prime movers such as motors to the required rotational speed and obtain greater torque. In many industries, such as various production lines in industrial production, construction machinery, mining machinery, and automobile manufacturing, speed reducers are indispensable components.

[0003] However, most existing speed reducers use belt drives, which leads to a series of problems such as efficiency loss, increased wear, and energy waste during transmission. Belts are also prone to loosening and slippage during long-term use, which may affect the stability and operating accuracy of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a dual-power gear transmission flat-head reducer. By setting a transmission mechanism, it can effectively achieve the effect of transmission and deceleration, enabling the system to operate stably under low speed and high torque. At the same time, compared with the traditional belt transmission system, this transmission mechanism is more stable and can significantly reduce the occurrence of slippage. It solves the problem that most existing reducers use belt transmission, which leads to a series of problems such as efficiency loss, increased wear, and energy waste during transmission.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a dual-power gear transmission flat-head reducer, including a reducer housing, a fixed frame is fixedly connected to the left outer wall of the reducer housing, and a power output mechanism is provided on the fixed frame;

[0007] The power output mechanism includes a left motor and a right motor fixedly connected to the outer wall of the left side of the fixed frame. The output end of the left motor is fixedly connected to a gear one via a coaxial keyway. The inner wall of the reducer housing is rotatably connected to a gear two. The gear one meshes with the gear two. The left side of the gear two is fixedly connected to a gear three. The gear two and the gear three are coaxially connected.

[0008] Furthermore, the output end of the right-side motor is connected to a flat-head cutter bar via a coaxial keyway to drive the flat-head cutter bar to rotate, and a hollow output shaft is rotatably connected to the inner wall of the reducer housing.

[0009] Furthermore, a fourth gear is fixedly connected to the outer wall of the hollow output shaft, and the third gear meshes with the fourth gear.

[0010] Furthermore, an adjusting seat outer sleeve is fixedly connected to the left side of the right motor, and an adjusting seat cover is fixedly connected to the left side of the adjusting seat outer sleeve. The adjusting seat cover has an internal thread in its center hole, and an adjusting screw is threadedly connected to the inner wall of the adjusting seat cover. The right end of the adjusting screw is rotatably fixedly connected to the adjusting inner sleeve bearing. The outer wall of the adjusting screw has a thread, and the adjusting seat cover is threadedly connected to the outer wall of the adjusting screw.

[0011] Furthermore, an adjusting inner sleeve is slidably connected to the inner wall of the adjusting seat outer sleeve, a fastening screw is threadedly connected to the outer wall of the adjusting screw, the adjusting screw is a reciprocating screw, the inner wall of the fastening screw is threadedly connected to the outer thread of the adjusting screw, and an adjusting handwheel is fixedly connected to the outer wall of the left end of the adjusting screw.

[0012] Furthermore, the right end of the adjusting inner sleeve is rotatably connected to an adjusting connecting rod via a bearing, the right end of the adjusting screw is rotatably connected to a bearing on the inner wall of the adjusting inner sleeve via a bearing, the right end of the adjusting connecting rod is fixedly connected to a flat-headed cutter bar, and the right end of the flat-headed cutter bar is fixedly connected to a flat-headed cutter holder.

[0013] Furthermore, the outer wall of the adjusting seat sleeve is provided with a scale, and the outer wall of the adjusting inner sleeve is fixedly connected with a scale indicator needle.

[0014] This utility model has the following beneficial effects:

[0015] 1. By incorporating a left-side motor, when the left-side motor drives gear one to rotate, it drives gear two to rotate, causing gear two and gear three to rotate synchronously. Gear three then drives gear four to rotate synchronously with the hollow output shaft. Since gear one is smaller than gear two, and gear three is smaller than gear four, the hollow output shaft rotates slower relative to gear one, thus achieving a transmission speed reduction effect. This design effectively achieves transmission speed reduction, enabling the system to operate stably under low-speed, high-torque conditions. Furthermore, compared to traditional belt drive systems, this transmission mechanism is more stable, significantly reducing slippage and providing more reliable power transmission. In terms of transmission efficiency, the gear reducer exhibits excellent performance, with a single-stage transmission efficiency exceeding 96.5%. Even in two-stage and three-stage transmission systems, the efficiency remains relatively high. Therefore, while improving system efficiency, it also reduces energy consumption. Moreover, this transmission mechanism design not only improves the accuracy of power response but also maintains good adaptability under various working conditions, greatly enhancing the practicality and versatility of the overall device.

[0016] 2. By loosening the fastening screws and rotating the adjusting handwheel, the adjusting inner sleeve can be moved left or right. The adjusting inner sleeve moves the adjusting connecting rod left or right, which in turn moves the flat-head cutter bar left or right. The flat-head cutter bar then moves the flat-head cutter holder left or right. The extension length of the flat-head cutter holder can be adjusted by observing the contact point between the scale indicator and the scale. After adjustment, the fastening screws can be turned to ensure they are tightly fitted to the left side of the adjusting seat cover, locking the adjustment screw and preventing loosening after adjusting the extension length of the flat-head cutter holder, thus ensuring the stability of the adjustment.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 As shown, this utility model is a dual-power gear transmission flat-head reducer, including a reducer housing 1, a fixed frame 9 fixedly connected to the left outer wall of the reducer housing 1, and a power output mechanism provided on the fixed frame 9.

[0029] The power output mechanism includes a left motor 2 and a right motor 3 fixedly connected to the outer left wall of the fixed frame 9. The output end of the left motor 2 is fixedly connected to a gear 4 via a coaxial keyway. A gear 5 is rotatably connected to the inner wall of the reducer housing 1, with gear 4 meshing with gear 5. A gear 6 is fixedly connected to the left side of gear 5, and gear 5 and gear 6 are coaxially connected. The output end of the right motor 3 is connected to a flat-head cutter bar 16 via a coaxial keyway. A hollow output shaft 8 is rotatably connected to the inner wall of the reducer housing 1, and a gear is fixedly connected to the outer wall of the hollow output shaft 8. Gear 4.7 meshes with gear 3. An adjusting seat outer sleeve 10 is fixedly connected to the left side of the right motor 3. An adjusting seat cover 20 is fixedly connected to the left side of the adjusting seat outer sleeve 10. The adjusting seat cover 20 has an internal thread in its center hole. An adjusting screw 11 is threadedly connected to the inner wall of the adjusting seat cover 20. The right end of the adjusting screw 11 is rotatably fixedly connected to the adjusting inner sleeve 12 bearing. The outer wall of the adjusting screw 11 has a thread, and the adjusting seat cover 20 is threadedly connected to the outer wall of the adjusting screw 11. A left motor 2 is installed, driving the left motor 2... When gear 4 rotates, it drives gear 5 to rotate, causing gear 5 and gear 6 to rotate synchronously. Gear 6 then drives gear 7 to rotate, causing gear 7 and the hollow output shaft 8 to rotate synchronously. Since gear 4 is smaller than gear 5, and gear 6 is smaller than gear 7, the hollow output shaft 8 rotates at a slower speed relative to gear 4, thus achieving a transmission speed reduction effect. This design effectively reduces transmission speed, allowing the system to operate stably under low speed and high torque conditions. Furthermore, compared to traditional belt drive systems, this transmission mechanism is more stable, significantly reducing slippage and providing more reliable power transmission. In terms of transmission efficiency, the gear reducer exhibits excellent performance, with a single-stage transmission efficiency exceeding 96.5%. Even in two-stage and three-stage transmission systems, the efficiency remains relatively high. Therefore, while improving system efficiency, it also reduces energy consumption. Moreover, this transmission mechanism design not only improves the accuracy of power response but also maintains good adaptability under various working conditions, greatly enhancing the practicality and versatility of the overall device.

[0030] The inner wall of the adjusting seat outer sleeve 10 is slidably connected to an adjusting inner sleeve 12. The outer wall of the adjusting screw 11 is threadedly connected to a fastening screw 14. The adjusting screw 11 is a reciprocating screw. The inner wall of the fastening screw 14 is threaded to the outer thread of the adjusting screw 11. The left end of the adjusting screw 11 is fixedly connected to an adjusting handwheel 13. The right end of the adjusting inner sleeve 12 is rotatably connected to an adjusting connecting rod 15 via a bearing. The right end of the adjusting screw 11 is rotatably connected to the bearing on the inner wall of the adjusting inner sleeve 12 via a bearing. The right end of the adjusting connecting rod 15 is fixedly connected to a flat-head cutter bar 16. The right end of the flat-head cutter bar 16 is fixedly connected to a flat-head cutter holder 17. The outer wall of the adjusting seat outer sleeve 10 is provided with a scale 18. The outer wall of the adjusting inner sleeve 12 is fixedly connected to a scale indicator needle 19. By loosening the fastening screw 14 and rotating the adjusting handwheel 13, the adjusting inner sleeve 12 can be moved to the left or right. The adjusting inner sleeve 12 moves the adjusting connecting rod 15 to the left or right, which in turn moves the flat-head cutter bar 16 to the left or right. The flat-head cutter bar 16 moves the flat-head cutter holder 17 to the left or right. The extension length of the flat-head cutter holder 17 can be adjusted by observing the contact point between the scale indicator needle 19 and the scale ruler 18. After adjustment, the fastening screw 14 can be turned so that it fits tightly against the left side of the adjusting seat cover 20, locking the rotation of the adjusting screw 11 to prevent loosening after adjusting the extension length of the flat-head cutter holder 17 and ensuring the firmness of the adjustment.

[0031] A specific application of this embodiment is as follows: By setting up a left-side motor 2, when the left-side motor 2 drives gear 4 to rotate, it will also drive gear 5 to rotate, so that gear 5 and gear 3 rotate synchronously. Gear 3 and 6 drive gear 4 to rotate, so that gear 7 and the hollow output shaft 8 rotate synchronously. The size of gear 4 is smaller than that of gear 2 and 5, and the size of gear 3 and 6 is smaller than that of gear 4 and 7. The hollow output shaft 8 rotates at a slower speed relative to gear 4, thereby achieving the effect of transmission speed reduction. Through this design, the transmission speed reduction effect can be effectively achieved, enabling the system to operate at low speeds and high torque. The transmission mechanism operates stably and, compared to traditional belt drive systems, is more stable, significantly reducing slippage and providing more reliable power transmission. In terms of transmission efficiency, the gear reducer exhibits excellent performance, with a single-stage transmission efficiency exceeding 96.5%. Even in two-stage and three-stage transmission systems, the efficiency is relatively high. Therefore, while improving system efficiency, it can also reduce energy consumption. Furthermore, the design of this transmission mechanism not only improves the accuracy of power response but also maintains good adaptability under various working conditions, greatly enhancing the practicality and versatility of the overall device.

[0032] By loosening the fastening screw 14 and rotating the adjusting handwheel 13, the adjusting inner sleeve 12 can be moved to the left or right. The adjusting inner sleeve 12 moves the adjusting connecting rod 15 to the left or right, which in turn moves the flat-head cutter bar 16 to the left or right. The flat-head cutter bar 16 moves the flat-head cutter holder 17 to the left or right. The extension length of the flat-head cutter holder 17 can be adjusted by observing the contact point between the scale indicator needle 19 and the scale ruler 18. After adjustment, the fastening screw 14 can be turned so that it fits tightly against the left side of the adjusting seat cover 20, locking the rotation of the adjusting screw 11 to prevent loosening after adjusting the extension length of the flat-head cutter holder 17 and ensuring the firmness of the adjustment.
