Description

Technical Field

[0001] This invention relates to the field of generator technology, specifically to a power take-off generator set with an adaptive tensioning power take-off transmission assembly. Background Technology

[0002] In a power take-off system consisting of a prime mover and a generator, the choice of transmission connection method directly affects the system's starting performance, operating efficiency, and cost.

[0003] In existing technologies, a common connection method is a direct rigid connection between the generator and the prime mover. In this method, the prime mover needs to synchronously drive the generator rotor to rotate when starting. Since the generator rotor has a certain moment of inertia, the resulting additional load increases the starting resistance torque of the prime mover. For prime movers such as diesel engines, this not only leads to starting difficulties but may also exacerbate the load on the starting system, affecting its reliability over long-term use.

[0004] To overcome the aforementioned problems, existing technologies have introduced power take-off (PTO) solutions with active clutches. This solution uses an active-controlled clutch, such as an electromagnetic clutch or a pneumatic / hydraulic clutch, between the prime mover and the generator. The engagement and disengagement of the clutch are controlled by an electrical control system. During startup, the control system keeps the clutch disengaged, allowing the prime mover to start under no-load conditions. Once the prime mover's speed stabilizes, the clutch is engaged to transfer power to the generator, effectively reducing the impact of starting load and starting current on the starting system. However, this solution requires independent clutch control circuits, relays, sensors, and pneumatic or hydraulic systems, resulting in excessively high overall costs and failing to meet economic requirements.

[0005] It is evident that existing power take-off (PTO) generator sets present a dilemma in their transmission connection methods: while rigid connections offer simplicity and low cost, the prime mover must overcome the generator rotor's rotational inertia during startup, resulting in high starting torque and poor starting performance. Conversely, while active clutches enable no-load starting of the prime mover and improve starting performance, they require additional electromagnetic, pneumatic, or hydraulic control and actuation systems, leading to increased complexity and cost. Therefore, current technologies struggle to effectively control transmission system costs while ensuring good generator set starting performance. Finding a balance between generator set starting performance and transmission system cost has become a pressing technical challenge in this field. Summary of the Invention

[0006] The purpose of this invention is to provide a power take-off generator set with an adaptive tensioning power take-off transmission assembly, which enables the prime mover to start under light load and eliminates the need for an electrical system.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a power take-off generator set with an adaptive tensioning power take-off transmission assembly, comprising a generator and a prime mover, wherein a related idle shaft is driven on the rotating shaft of the generator, and a related short shaft is driven on the rotating shaft of the prime mover, the related idle shaft and the related short shaft being coaxially corresponding and rotating relative to each other, thereby forming a structural transmission connection between the generator and the prime mover through the adaptive tensioning power take-off transmission assembly; the adaptive tensioning power take-off transmission assembly comprises: a guide plate fixedly disposed on the related short shaft, an outer related ring fixedly disposed on the guide plate, and a [missing information - likely a component or element] disposed on the outer related ring. The inner connecting arc plate, the outer connecting ring and the connecting arc plate are in frictional contact, and a square socket is fixedly installed on the connecting arc plate. The square socket moves in a direction perpendicular to the axis of the connecting hollow shaft. A tensioning rod is provided on the outside of the connecting hollow shaft, and a counterweight is provided on the outside of the tensioning rod. When the connecting hollow shaft rotates with the generator, the counterweight applies pressure to the square socket through the tensioning rod under the action of centrifugal force, so that the contact pressure between the outer connecting ring and the connecting arc plate increases with the increase of the generator speed, thereby realizing the adaptive power take-off transmission from the prime mover to the generator.

[0008] An externally fixed frame is provided for the associated hollow shaft. A frame groove is provided on the frame. The square socket is limited through the frame groove, so that the square socket can only move perpendicular to the axial direction of the associated hollow shaft.

[0009] A through-shaft groove is provided through the associated hollow shaft, and a through-shaft pusher is fixedly provided on the square socket, the through-shaft pusher passing through the through-shaft groove; a strip groove is provided on the through-shaft pusher, and an inner pressure shaft is fixedly provided on the tensioning rod, the inner pressure shaft being inserted into the strip groove.

[0010] A support shaft is fixedly provided on the surface of the associated hollow shaft, and the tensioning rod rotates around the support shaft. When the counterweight is subjected to centrifugal force, it drives the tensioning rod to rotate, so that the inner pressure shaft applies pressure to the through shaft pusher through the strip groove.

[0011] The end of the tensioning rod is provided with a first elastic element, which is located between the tensioning rod and the associated hollow shaft. The first elastic element applies pressure to the tensioning rod to ensure that the outer associated ring and the associated arc plate are in frictional contact when the associated hollow shaft is not rotating.

[0012] The guide plate has an air chamber inside, and fins are provided on the inner wall of the air chamber. When the outer connecting ring heats up, the heat is conducted to the guide plate to heat the gas in the air chamber.

[0013] The associated short shaft has an end blind hole and a gas flow channel inside; one end of the end blind hole is open and the other end is bottom, and its bottom is connected to the gas chamber through the gas flow channel; a piston body is provided in the end blind hole, and there is a sliding seal contact between the piston body and the end blind hole; a synchronous spindle is provided on one side of the piston body, and the piston body is used to drive the synchronous spindle to move axially, and the piston body and the synchronous spindle rotate relative to each other.

[0014] The synchronous mandrel is fixedly provided with double-sided clamping plates, which extend to the outside of the associated hollow shaft and are clamped on both sides of the counterweight. When the synchronous mandrel moves axially, the double-sided clamping plates synchronously drive the counterweight to move axially. The associated hollow shaft is provided with a third elastic member, which applies elastic force to the synchronous mandrel, causing the synchronous mandrel to tend to move in the direction of the end blind hole.

[0015] The inner surface of the outer connecting ring is provided with slots, which are distributed in a circular array.

[0016] The square socket has a limiting groove and an expansion cavity inside, and the expansion cavity is connected to the outside through the limiting groove. A centrifugal locking piece is inserted into the limiting groove, and a second elastic element is provided in the expansion cavity. The second elastic element is connected to the centrifugal locking piece. When the rotational speed of the associated empty shaft reaches a set threshold, the centrifugal force on the centrifugal locking piece is greater than the elastic tension of the second elastic element, and the centrifugal locking piece extends outward and is inserted into the slot.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The power take-off generator set with adaptive tensioning power take-off transmission assembly of the present invention achieves light-load start-up of the prime mover through the relative sliding of the outer connecting ring and the connecting arc plate during startup. As the generator speed increases, the contact pressure between the outer connecting ring and the connecting arc plate is gradually increased by the centrifugal force of the counterweight, thereby gradually engaging the power take-off and improving the starting stability of the prime mover.

[0019] 2. This invention, through the combination of a tensioning rod, an air chamber, and an end blind hole, enables adaptive tension adjustment. Under frequent start-stop conditions, when the outer connecting ring and connecting arc plate heat up due to friction from multiple short-term start-stop cycles, the adaptive tension adjustment allows the connecting arc plate to pressurize faster. As the generator speed increases slightly, the outer connecting ring and connecting arc plate are quickly pressed together, resulting in a rapid increase in transmitted torque and reducing the relative friction and sliding time between the two. This prevents a rapid reduction in the lifespan of the outer connecting ring and connecting arc plate under high-temperature conditions. Conversely, when the outer connecting ring and connecting arc plate are at low temperatures, the pressure increase of the connecting arc plate is slower, and the clamping force increases gradually with the generator speed. The outer connecting ring and connecting arc plate remain in a semi-clutch relative sliding state for a longer period, focusing more on the light-load start-up of the prime mover.

[0020] 3. Through the combination of centrifugal locking plates and slots, this invention can completely lock the outer connecting ring and connecting arc plate after the generator speed reaches a constant operating range, avoiding slippage heating and wear, and improving power take-off transmission efficiency.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 9 This invention provides a technical solution: a power take-off generator set with an adaptive tensioning power take-off transmission assembly. This invention proposes an automatic and gradual power take-off engagement scheme for light-load starting of the prime mover, eliminating the need for power system control, reducing cost, and broadening application scenarios. Specific embodiments are as follows:

[0038] Example 1:

[0039] The generator set of this invention includes a generator 1 and a prime mover, the prime mover being a diesel engine (details omitted in the accompanying drawings). The generator 1 is equipped with a drive shaft 2, and the prime mover is equipped with a drive shaft 3, as shown below. Figure 4 As shown, the ends of the associated hollow shaft 2 and the associated short shaft 3 are integrally machined with bushings 209, which are combined with... Figure 6 As shown, a keyway 210 is provided on the inner wall of the bushing 209. The associated hollow shaft 2 is connected to the rotating shaft of the generator 1 through the bushing 209, and the associated short shaft 3 is connected to the rotating shaft of the prime mover through the bushing 209. The associated hollow shaft 2 in this invention is a tubular shaft with a cylindrical cavity inside.

[0040] like Figure 4 As shown, the associated empty shaft 2 and the associated short shaft 3 are coaxially corresponding and rotate relative to each other. A guide plate 4 is welded and fixed on the associated short shaft 3. The guide plate 4 is made of a metal with good thermal conductivity, such as copper. An outer associated ring 5 is fixed on the guide plate 4. The outer associated ring 5 is circular and is coaxially arranged with the associated short shaft 3. An associated arc plate 6 is provided on the inner side of the outer associated ring 5. The outer associated ring 5 and the associated arc plate 6 are in frictional contact. The outer associated ring 5 and the associated arc plate 6 are made of the same material, both of which are composed of ceramic particles and metal adhesive, resulting in a high coefficient of friction.

[0041] A square socket 7 is fixedly installed on the associated arc plate 6. The square socket 7 moves perpendicular to the axial direction of the associated hollow shaft 2, such as... Figure 8 As shown, an arc-shaped support 705 is welded and fixed on the square socket 7. The arc-shaped support 705 is in the shape of an arc plate, and the curvature is consistent with that of the associated arc plate 6. The arc-shaped support 705 is fixedly installed on the outside of the associated arc plate 6 to support and fix the associated arc plate 6.

[0042] like Figure 9 As shown, a tensioning rod 8 is provided outside the associated hollow shaft 2, and a counterweight 9 is provided outside the tensioning rod 8. When the associated hollow shaft 2 rotates, the counterweight 9 applies pressure to the square socket 7 through the tensioning rod 8 under the action of centrifugal force, thereby increasing the contact pressure between the outer associated ring 5 and the associated arc plate 6.

[0043] like Figure 7 As shown, an external frame 201 is fixedly provided on the outside of the associated hollow shaft 2. A frame groove 202 is provided on the frame 201. The square socket 7 is limited through the frame groove 202, and the frame groove 202 limits the square socket 7 so that the square socket 7 can only move perpendicular to the axial direction of the associated hollow shaft 2.

[0044] like Figure 9 As shown, a through-shaft groove 203 is provided through the associated hollow shaft 2, and a through-shaft pusher 204 is fixedly provided on the square socket 7. The through-shaft pusher 204 passes through the through-shaft groove 203, as shown. Figure 8 As shown, a strip groove 205 is provided on the through-shaft pusher 204, and an inner pressure shaft 206 is fixedly provided on the tensioning rod 8. The inner pressure shaft 206 is inserted into the strip groove 205. Through the elongated arrangement of the strip groove 205, the inner pressure shaft 206 has a horizontal movement clearance when the tensioning rod 8 rotates.

[0045] A support shaft 207 is fixedly installed on the surface of the associated hollow shaft 2, and the tensioning rod 8 rotates with the support shaft 207 as the fulcrum. When the counterweight 9 is subjected to centrifugal force, it drives the tensioning rod 8 to rotate, so that the inner pressure shaft 206 applies pressure to the through shaft pusher 204 through the strip groove 205.

[0046] The end of the tension rod 8 is provided with a first elastic element 208, which is a spring. The first elastic element 208 is located between the tension rod 8 and the associated hollow shaft 2. The tension rod 8 is subjected to pressure by the first elastic element 208 to ensure that the outer associated ring 5 and the associated arc plate 6 are in frictional contact when the associated hollow shaft 2 is not rotated.

[0047] Example 2:

[0048] The difference from Embodiment 1 is that an air chamber 401 is further provided inside the guide plate 4, and fins 402 are provided on the inner wall of the air chamber 401. The fins 402 increase the heat exchange area between the guide plate 4 and the gas inside the air chamber 401. When the outer connecting ring 5 heats up, the heat is conducted to the guide plate 4 to heat the gas in the air chamber 401.

[0049] The internal structure of the short shaft 3 is provided with an end blind hole 301 and a gas flow channel 302. One end of the end blind hole 301 is open and the other end is the bottom. The bottom of the end blind hole 301 is connected to the gas chamber 401 through the gas flow channel 302. A piston body 303 is provided in the end blind hole 301. The piston body 303 and the end blind hole 301 are in sliding sealing contact. A synchronous spindle 304 is provided on one side of the piston body 303. The piston body 303 is used to drive the synchronous spindle 304 to move axially. The piston body 303 and the synchronous spindle 304 rotate relative to each other.

[0050] A double-sided clamping plate 305 is fixedly mounted on the synchronous spindle 304. The double-sided clamping plate 305 extends outside the associated hollow shaft 2 and is clamped on both sides of the counterweight 9. When the synchronous spindle 304 moves axially, the double-sided clamping plate 305 synchronously drives the counterweight 9 to move axially. A third elastic member 306 is provided inside the associated hollow shaft 2. The third elastic member 306 is a spring. The third elastic member 306 applies elastic force to the synchronous spindle 304, causing the synchronous spindle 304 to tend to move in the direction of the end blind hole 301. The third elastic member 306 assists the piston body 303 in resetting and moving.

[0051] Example 3:

[0052] The difference from Embodiment 1 is that a slot 501 is further formed on the inner surface of the outer connecting ring 5, such as... Figure 5 As shown, the card slots 501 are arranged in a circular array.

[0053] The square socket 7 has a limiting groove 701 and an expansion cavity 702 inside. The expansion cavity 702 is connected to the outside through the limiting groove 701. A centrifugal locking piece 703 is inserted into the limiting groove 701 for limiting. A second elastic element 704, which is a tension spring, is provided in the expansion cavity 702 and is connected to the centrifugal locking piece 703. When the rotational speed of the associated empty shaft 2 reaches a set threshold, the centrifugal force on the centrifugal locking piece 703 is greater than the elastic tension of the second elastic element 704. The centrifugal locking piece 703 extends outward and inserts into the slot 501. By setting the tension of the second elastic element 704 and the weight of the centrifugal locking piece 703, the extension action of the centrifugal locking piece 703 at the corresponding rotational speed can be controlled.

[0054] Taking Embodiment 1 as an example, the generator set of the present invention is as follows: Figure 8 and Figure 9 As shown, initially, an initial elastic force is applied to one end of the tensioning rod 8 by the first elastic member 208, so that the tensioning rod 8 applies initial pressure to the associated arc plate 6 through the through-shaft push member 204 and the square socket 7, ensuring that the outer associated ring 5 and the associated arc plate 6 are in frictional contact when the associated empty shaft 2 is not rotated.

[0055] When the prime mover starts and drives the associated short shaft 3 to rotate, the associated short shaft 3 drives the guide plate 4 and the outer associated ring 5 to rotate synchronously. The outer associated ring 5 applies rotational torque to the associated arc plate 6 through friction. At this time, the outer associated ring 5 and the associated arc plate 6 are in a semi-linkage state. The associated arc plate 6 and the associated empty shaft 2 and other structures gradually increase their speed in the semi-linkage state.

[0056] The prime mover starts under light load through the semi-linkage contact between the outer connecting ring 5 and the connecting arc plate 6. As the rotational speed of the connecting empty shaft 2 gradually increases, the centrifugal force on the counterweight 9 gradually increases. Under the action of centrifugal force, the counterweight 9 applies an outward driving force to the tension rod 8, causing the tension rod 8 to apply pressure to the through-shaft pusher 204 and the square socket 7 with the support shaft 207 as the fulcrum, thereby gradually increasing the contact pressure between the outer connecting ring 5 and the connecting arc plate 6. It is worth noting that when the connecting empty shaft 2 rotates, the connecting arc plate 6 itself is also subjected to centrifugal force, which increases the contact pressure between the outer connecting ring 5 and the connecting arc plate 6. Through the setting of the tension rod 8 and the lever principle, the pressure generated by the centrifugal force can be increased.

[0057] When generator 1 reaches its operating speed, the frictional force generated by the pressure between the outer connecting ring 5 and the connecting arc plate 6 must be greater than the transmission torque to ensure that the two can be locked together.

[0058] Taking Example 2 as an example, under the condition of frequent start-stop of the generator set, the outer connecting ring 5 and the connecting arc plate 6 may have multiple semi-clutch frictions in a short period of time. The heat generation rate is greater than the heat dissipation rate. The heat accumulation causes the outer connecting ring 5 and the connecting arc plate 6 to heat up. When the temperature of the outer connecting ring 5 and the connecting arc plate 6 is high, the friction will reduce the lifespan more quickly.

[0059] This invention features adaptive tension adjustment. Under frequent start-stop conditions, the generator set shifts its focus from light-load starting to extending the lifespan of the external associated ring 5 and associated arc plate 6. This maximizes the benefits because during frequent starts, the prime mover, such as a diesel engine, is not fully cooled and remains in a hot state. The engine oil has not yet settled, making starting easier. In this case, the emphasis on light-load starting can be reduced, while the focus on protecting the lifespan of the external associated ring 5 and associated arc plate 6 can be increased.

[0060] Specifically, when frequent start-stop conditions cause the outer connecting ring 5 to reach high temperatures, the heat from the outer connecting ring 5 is conducted to the guide plate 4, causing the gas in the gas chamber 401 to heat up. The upper limit of the operating temperature of the outer connecting ring 5 and the connecting arc plate 6 is approximately 200 degrees Celsius. Exceeding this temperature limit will accelerate wear. Therefore, when the outer connecting ring 5 rises from room temperature to approximately 200 degrees Celsius, the pressure generated by the expansion of the gas in the gas chamber 401 due to the temperature rise is input into the end blind hole 301 through the gas flow channel 302, which can push the piston body 303 to move to the left. Figure 4As shown in the diagram, the gas volume in the gas chamber 401 is determined according to the diameter of the piston body 303, ensuring that the gas pressure acting on the piston body 303 can complete a sufficient stroke drive under the corresponding temperature rise.

[0061] like Figure 4 As shown, the piston body 303 drives the synchronous spindle 304 and the double-sided clamping plates 305 to move to the left, compressing the third elastic element 306, and combining... Figure 6 and Figure 7 As shown, when the two side clamps 305 move to the left, they can push the counterweight 9 to move to the left.

[0062] When the counterweight 9 moves to the left, increasing the distance between it and the support shaft 207, at the same rotational speed of the associated empty shaft 2, the tensioning rod 8 will increase the pressure applied to the associated arc plate 6. This results in faster pressure build-up on the associated arc plate 6, allowing the generator 1 to quickly press the outer associated ring 5 and the associated arc plate 6 together as soon as its speed increases slightly. This leads to a rapid increase in transmitted torque, reduces the relative friction and sliding time between the two, and prevents a rapid reduction in the lifespan of the outer associated ring 5 and the associated arc plate 6 under high-temperature conditions.

[0063] Similarly, when the outer connecting ring 5 and the air chamber 401 return to low temperature, the negative pressure generated by the third elastic element 306 and the gas contraction will reduce the distance between the counterweight 9 and the support shaft 207. At this time, the pressure of the connecting arc plate 6 increases more slowly, and the clamping force increases gradually with the speed of the generator 1. The outer connecting ring 5 and the connecting arc plate 6 are in a semi-linked relative sliding state for a longer time, which focuses more on the light-load start of the prime mover.

[0064] Taking Example 3 as an example, such as Figure 5 As shown, during the rotation of generator 1, centrifugal locking plate 703 rotates synchronously and is subjected to centrifugal force. The working speed of generator 1 in this invention is 1500 r / min. When generator 1 reaches 1400 r / min, the centrifugal force on centrifugal locking plate 703 is greater than the elastic tension of the second elastic member 704. At this time, centrifugal locking plate 703 will extend from the limiting groove 701 and insert into the slot 501, so that the outer connecting ring 5 and the connecting arc plate 6 are completely rigidly locked, avoiding slippage heating and wear, and improving the power take-off transmission efficiency.

[0065] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
