Description

Technical Field

[0001] This utility model relates to the field of power generation equipment technology, and in particular to a power take-off power generation system transmission device. Background Technology

[0002] Power take-off (PTO) generators typically use an engine as the driving device, transmitting power to a generator through a mechanical transmission system. Common transmission methods include belt drive, gear drive, and chain drive. These methods can efficiently convert the mechanical energy of the power source into electrical energy. Taking vehicle PTO generators as an example, a PTO is usually installed at the engine's power output end. The engine's power is extracted using gear drive and then transmitted to the generator through a belt or coupling. This allows for a stable power supply to onboard equipment and temporary power facilities while the vehicle is in motion.

[0003] Application No. 202420326461.7 discloses a power take-off (PTO) system transmission device, including a diesel engine. A drive wheel is fixedly connected to the output shaft of the diesel engine. A large pulley is detachably mounted on the surface of the drive wheel via bolts. A mounting bracket is detachably mounted on the outer wall of the diesel engine via bolts. Multiple sets of tension wheel mounting holes are formed on the surface of the mounting bracket. A connecting bracket is detachably mounted on the surface of the multiple sets of tension wheel mounting holes via bolts. The outer wall of the tension wheel contacts the outer wall of the belt. A tension wheel is rotatably connected to the surface of the connecting bracket. A PTO is detachably mounted on the mounting hole of the PTO via bolts. In this invention, the transmission ratio between the large pulley and the small pulley is between 2 and 2.5, and the transmission device can transmit 30kW to 50kW of power. The design of the large pulley nested within the diesel engine's belt drive wheel reduces the protruding size of the large pulley, minimizing modifications to the vehicle during installation.

[0004] The above solution has shortcomings in use. When the belt tension needs to be adjusted, the tensioning wheel needs to be disassembled and the installation position adjusted, which is quite troublesome. Moreover, the equipment needs to be stopped during the adjustment process, which increases the non-productive time of the equipment and seriously affects the continuity and reliability of the power take-off system. Therefore, we provide a power take-off system transmission device. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] First Embodiment

[0032] As attached Figure 1 To be continued Figure 5 As shown: A power take-off (PTO) power generation system transmission device includes a diesel engine 1, a large pulley 2 installed at the output end of the diesel engine 1, a generator 3 mounted on the diesel engine 1, a transmission belt 4 connecting the generator 3 and the large pulley 2, and a tensioning pulley 6 mounted above the transmission belt 4. When the diesel engine 1 is working, it drives the large pulley 2 to rotate, and the large pulley 2 drives the generator 3 to rotate through the transmission belt 4, thereby completing the power generation work. A fixed frame 5 is rotatably connected to the outside of the tensioning pulley 6 and is used to stabilize the tensioning pulley 6. The fixed frame 5 can stabilize the tensioning pulley 6 and keep it in a taut state above the transmission belt 4.

[0033] The adaptive component 7 includes a U-shaped frame 701 positioned above the fixed frame 5 and an adaptive structure mounted on the U-shaped frame 701. The adaptive structure includes a slide rod 702 slidably connected to the bottom surface of the U-shaped frame 701. The bottom end of the slide rod 702 is connected to the upper surface of the fixed frame 5. A holding spring 703 is sleeved on the outer surface of the slide rod 702. The holding spring 703, through its own elastic deformation and restoring force, consistently applies a stable and continuous holding force to the fixed frame 5. The tension wheel 6 connected to the fixed frame 5 moves downward accordingly, precisely... It fits above the transmission belt 4, keeping the transmission belt 4 in an ideal tension state, ensuring efficient and stable power transmission. After the transmission belt 4 rotates at high speed for a long time, due to the continuous tension, the rubber material of the transmission belt 4 will gradually fatigue and age, and the internal fiber structure will loosen, inevitably resulting in loosening. At this time, the pressure received by the top spring 703 decreases and it will immediately extend to push the fixed frame 5 down, which can smoothly and accurately drive the tensioning wheel 6 to move down, supporting the transmission belt 4 and keeping it in a tension state.

[0034] A limiting plate 704 is fixedly connected to the top of the slide rod 702. The limiting plate 704 can restrict the descent of the slide rod 702 to prevent the slide rod 702 from detaching from the bottom of the U-shaped frame 701. A set of fixing plates 705 are fixedly connected to the rear end of the U-shaped frame 701. Each fixing plate 705 is provided with a set of connecting bolts 706. By using the cooperation of the fixing plates 705 and the connecting bolts 706, the U-shaped frame 701 can be installed on the diesel engine 1, thereby ensuring the stability of the fixing frame 5 and the tensioning wheel 6.

[0035] The buffer structure includes a set of guide plates 707 slidably connected to the bottom surface of the U-shaped frame 701. The bottom end of each guide plate 707 is connected to the upper surface of the fixed frame 5. Each guide plate 707 has a set of equidistantly arranged triangular slots 708 on its left and right sides. Each guide plate 707 has a vertical plate 709 on its left and right sides. The bottom end of each vertical plate 709 is connected to the upper surface of the bottom end of the U-shaped frame 701. A set of support rods 710 are fixedly connected to the side of each set of vertical plates 709 that are close to each other. A movable plate 711 is slidably connected to the outer surface of each set of support rods 710. A triangular block 712 is fixedly connected to the side of each set of movable plates 711 that are close to each other. A return spring 713 is sleeved on the outside of each support rod 710. The ends of each set of return springs 713 that are far apart from each other are respectively connected to the side of each set of vertical plates 709 that are close to each other. When the tensioning wheel 6 is subjected to vibration and impact, the fixed frame 5 will drive the guide plate 707 during its movement. The triangular slot 708 will then apply a squeezing force to the triangular block 712. After being subjected to force, the triangular block 712 will gradually disengage from the triangular slot 708 and push the connected moving plate 711, causing the moving plate 711 to compress the return spring 713. As the guide plate 707 continues to move, when the triangular block 712 and the triangular slot 708 are in position, the return spring 713 will extend and push the triangular block 712 to quickly insert it into the triangular slot 708. During the entire vibration response process, the continuous squeezing, disengaging and resetting actions between the triangular block 712 and the triangular slot 708 generate a significant frictional damping effect, converting the vibration energy borne by the tensioning wheel 6 into frictional heat energy, further enhancing the stability of the tensioning wheel 6 under complex vibration conditions.

[0036] Second Embodiment

[0037] As attached Figure 1 Appendix Figure 2 With appendix Figure 6As shown: Lubrication assembly 8, mounted on the fixed frame 5, is used to lubricate the exterior of the tension pulley 6, reducing the friction between it and the transmission belt 4. The lubrication assembly 8 includes an oil supply pipe 801 embedded in the front of the fixed frame 5. The outer surface of the oil supply pipe 801 is connected to a set of equidistantly arranged oil outlets 802. The oil supply pipe 801 can deliver lubricant, allowing it to drip from the oil outlets 802 onto the surface of the tension pulley 6. This reduces the friction between the tension pulley 6 and the transmission belt 4, further reducing the heat generated by friction and preventing the transmission belt 4 from overheating, aging, and deforming, thereby extending the service life of the transmission belt 4. The lower side of the oil supply pipe 801... The frame is equipped with a brush 803, the front and rear ends of which are connected to the inner side of the fixed frame 5. When the tension wheel 6 rotates, the brush 803 will apply the lubricating oil dripping onto its exterior, so that the lubricating oil is evenly distributed on the surface of the tension wheel 6. The input end of the oil supply pipe 801 is connected to an oil reservoir 804. The top of the oil reservoir 804 is detachably equipped with a sealing cap. The exterior of the oil reservoir 804 is equipped with a viewing window. The oil reservoir 804 can be used to hold lubricant, so that lubricant can be continuously injected into the oil supply pipe 801. The remaining amount of lubricant inside the oil reservoir 804 can be observed through the viewing window, so that the staff can add lubricant in time.

[0038] Working principle: When the transmission belt 4 enters the transmission working state, the top spring 703 will always apply a stable and continuous top force to the fixed frame 5 by the restoring force generated by its own elastic deformation. The tension wheel 6 connected to the fixed frame 5 moves down accordingly and fits precisely above the transmission belt 4, so that the transmission belt 4 is kept in an ideal tension state, ensuring efficient and stable power transmission. After the transmission belt 4 rotates at high speed for a long time, due to the continuous tension, the rubber material of the transmission belt 4 will gradually fatigue and age, and the internal fiber structure will loosen, inevitably resulting in loosening. At this time, the pressure received by the top spring 703 decreases and it will immediately extend to push the fixed frame 5 down, which can smoothly and accurately drive the tension wheel 6 to move down accordingly, supporting the transmission belt 4 and keeping it in a tension state.

[0039] When the tension wheel 6 is subjected to vibration and impact, it will cause the fixed frame 5 to move against the resistance of the holding spring 703. The movement of the fixed frame 5 will compress or stretch the holding spring 703, quickly converting some of the vibration energy into the elastic potential energy of the spring. At the same time, the fixed frame 5 will drive the guide plate 707 during its movement, and the triangular slot 708 will apply a squeezing force to the triangular block 712. After being subjected to force, the triangular block 712 will gradually disengage from the triangular slot 708 and push the connected moving plate 711, causing the moving plate 711 to compress the return spring 713. As the guide plate 707 continues to move, when the triangular block... When 712 is engaged with the triangular slot 708, the return spring 713 extends and pushes the triangular block 712 to quickly insert it into the triangular slot 708. During the entire vibration response process, the continuous squeezing, disengaging and resetting actions between the triangular block 712 and the triangular slot 708 generate a significant frictional damping effect, converting the vibration energy borne by the tensioning wheel 6 into frictional heat energy, further enhancing the stability of the tensioning wheel 6 under complex vibration conditions. It eliminates the need for frequent disassembly and installation of the tensioning wheel 6 to adjust the tension, and eliminates the need to stop the equipment for operation, further ensuring the continuity and reliability of the power take-off system.
